Description

  The present invention relates to a knitted lace having high stretchability in at least one of the wale direction and the course direction, and a knitted lace using the lace knitted fabric.

  A first conventional knitted lace fabric is disclosed in Patent Document 1, for example. In this knitted lace fabric, a heat-soluble heat-bonding yarn is knitted into the scalloped portion. By heating the knitted lace fabric after knitting, the thermal bonding yarn is melted. The thermal bonding yarn bonds the overlapping portion between the base portion of the picot yarn and the other yarn, and dissolves and removes the exposed portion of the thermal bonding yarn other than the overlapping portion. As a result, this prior art is configured to prevent fraying at the scalloped portion of the knitted lace.

  A second conventional knitted lace fabric is disclosed in Patent Document 2, for example. In this lace fabric, the covering yarn is knitted into the scalloped portion. The covering yarn is composed of a core yarn having heat melting property and a covering yarn which is a thermoplastic synthetic fiber yarn. By heating the knitted lace fabric after knitting, a part of the core yarn of the covering yarn is melted, and the melted material oozes out from between the coated yarns. Then, the melt is solidified by adhering other adjacent yarns. As a result, this prior art is configured to prevent fraying at the scalloped portion of the knitted lace.

Japanese Examined Patent Publication No. 63-52142 Japanese Patent Laid-Open No. 11-81073

  In the first and second prior arts, since the insertion yarn is laid across the course, the shape stability is low. In particular, when spandex is used alone as the insertion yarn, the width between the courses is narrow. There is a problem that it becomes difficult to dye.

  Accordingly, an object of the present invention is to provide a knitted lace and a knitted lace that have high stretchability and shape stability in both the wale direction and the course direction and can be three-dimensionally formed by molding or the like. And

The present invention is a lace knitted fabric having a chain stitch structure in which a plurality of loop-shaped portions are formed by a chain stitch yarn,
The chain stitch structure has a portion into which an insertion yarn having a lower melting temperature than the chain stitch yarn is knitted,
The chain knitting structure includes a plurality of first loop-shaped portions and second loop-shaped portions alternately arranged in a predetermined course direction, and the second loop-shaped portion of interest is the course direction of the second loop-shaped portion. A first loop-like portion extending through the first loop-like portion in the front stage and extending toward the rear stage in the course direction, and a first loop-like portion in the same stage in the course direction as the second loop-like portion is passed through. By being connected to the part, it is formed in a chain and extends in the course direction,
The insertion yarn is a knitted lace fabric having stretchability.

  Further, the present invention is characterized in that the insertion yarn extends along a wale formed by connecting a plurality of loop-shaped portions, and is knitted into a chain stitch structure.

  In the invention, it is preferable that the insertion yarn is a covering yarn, and the core yarn has heat melting property.

Further, the present invention has a portion in which the thermal bonding yarn and the insertion yarn are knitted in the chain stitch structure, and in the portion where the thermal bonding yarn and the insertion yarn are both knitted, The insertion yarn is inserted between the loop-shaped portions, and the thermal bonding yarn is inserted between the insertion yarn and the first loop-shaped portion.
Moreover, this invention is the knitted lace manufactured by the said lace fabric.

  According to the present invention, by heating the lace knitted fabric to a temperature lower than the melting temperature of the chain knitting yarn and higher than the melting temperature of the insertion yarn, a part of the insertion yarn is partially dissolved. A part of the dissolved portion adheres to the chain stitch yarn. By solidifying in this state, it is possible to prevent the chain knitting yarn in contact with the insertion yarn from being released from the insertion yarn in the knitted lace manufactured using the lace knitted fabric. Further, the chain knitting yarns in contact with the insertion yarn can be bonded to each other by the insertion yarn. As a result, the connected state of the chain stitch yarn is maintained, and fraying of the yarn can be prevented.

  As described above, in the present invention, the binding of the chain stitch structure is strengthened at the attachment portion where the insertion yarn adheres to another yarn. Even if a part of the chain stitch yarn constituting the chain stitch structure is cut off by this, the unraveling of the chain stitch structure is prevented at the adhered portion, and the chain stitch structure is prevented from being unraveled beyond the adhered portion. it can.

  In addition, since a part of the insertion yarn adheres to a portion where the insertion yarn and the chain stitch yarn intersect, it is possible to prevent the insertion yarn from shifting or separating from the chain stitch structure. Further, when the insertion yarn extends over the two adjacent chain knitting yarns, the two adjacent chain knitting yarns are prevented from separating from each other by adhering the insertion yarn to each chain knitting yarn.

  As described above, according to the present invention, fraying of the chain knitting yarn can be prevented in the knitted lace manufactured by heating the knitted lace fabric. For example, it is possible to prevent fraying of yarn caused by a manufacturing state such as sewing or cutting of a knitted lace, and fraying of yarn caused by a use state such as wearing or washing, and quality can be improved. Further, since the chain stitch structure is achieved with yarns other than the insertion yarn, the form of the entire knitted lace can be stabilized by using a yarn having heat resistance as the chain stitch yarn.

  Further, the amount of melt of the insertion yarn can be reduced, the influence of the melted portion on the entire knitted lace can be reduced, and the pattern pattern can be prevented from being damaged. Further, since the chain knitting yarn can be made thin, the knitted lace can be made soft, in other words, easily deformed. Thereby, for example, knitted lace can be suitably used as a fabric such as underwear.

  Further, according to the present invention, since the insertion yarn extends along the wale and is knitted into the chain stitch structure, the binding in the knitting direction can be increased for the chain stitch structure. As a result, it is possible to reduce or eliminate the laterally oscillating portion of the chain knitting yarn, that is, the run stop portion, which is formed to prevent the chain knitting structure from fraying. As described above, according to the present invention, since the run stop portion formed on the knitted lace with the knitted lace fabric heated can be reduced, the yarn can be prevented from undesirably extending between adjacent wales. , Aesthetics can be further improved.

  Further, according to the present invention, since the core yarn has a heat melting property, when the lace knitted fabric is heated, the portion of the insertion yarn that contacts the chain knitting yarn is melted to form the chain knitting yarn. Adhere to.

  As described above, according to the present invention, the exposed portion of the insertion yarn that comes into contact with the other yarn becomes a portion that adheres to the other yarn, thereby increasing the amount of attachment of the insertion yarn to the other yarn. And the adhesive strength can be improved. Therefore, fraying of each yarn can be more reliably prevented.

  According to the present invention, in the portion where the thermal bonding yarn and the insertion yarn are knitted together, the insertion yarn is inserted between the first loop portion and the second loop portion, and the insertion yarn and the first loop portion. Therefore, the insertion yarn and the thermal bonding yarn are knitted into the chain stitch structure by inserting between the first loop-shaped portion and the second loop-shaped portion. In the lace knitted fabric, the surface on the side on which the first loop-shaped portion is arranged is the back surface with respect to the stretchable insertion yarn knitted into the chain stitch structure, and the opposite surface is the front surface. Become. In the present invention, the insertion yarn is disposed on the front side of the thermal bonding yarn in a portion where the thermal bonding yarn and the insertion yarn are knitted in common. Therefore, when the knitted lace fabric is viewed from the front surface, the thermal bonding yarn and the first loop-shaped portion are hidden by the insertion yarn.

  Thus, the thermal bonding yarn can be hidden by the insertion yarn, and the thermal bonding yarn can be made difficult to see from the front surface. This makes it possible to clarify the pattern formed on the knitted lace formed by heating the knitted lace fabric. Even if the heat-bonding yarn is melted, the influence on the pattern viewed from the front surface can be reduced. The thermal bonding yarn passes between the first loop-shaped portion and the insertion yarn, whereby the first loop-shaped portion and the insertion yarn can be bonded, and the insertion yarn is detached from the chain stitch structure. Can be prevented.

  Further, according to the present invention, the knitted lace can be stretched by the stretchable insertion yarn being knitted into the chain stitch structure in a stretched state. Further, by heating such a knitted lace after knitting, a part of the insertion yarn adheres to the chain knitting yarn at a portion where the insertion yarn and the chain knitting yarn are in contact with each other. This can prevent the chain stitch yarn from coming out of the chain stitch structure. Thus, for example, it is possible to prevent the chain knitting yarn from coming out of the sewing portion.

  Thus, according to the present invention, fraying of the yarn can be prevented even in the knitted lace having stretchability by knitting the insertion yarn into the chain stitch structure. Further, even if the knitted lace repeatedly expands and contracts after knitting, the yarns are prevented from shifting due to the insertion yarns. As a result, the pattern of the knitted lace at the time of expansion / contraction can be prevented from greatly differing from the pattern of the knitted lace before the expansion / contraction, and the aesthetic sense of the knitting lace can be maintained for a long time.

  Further, by heating the above-described knitted lace fabric, a part of the insertion yarn included in the knitted lace fabric is melted, and the binding of the respective yarns is strengthened. Therefore, fraying about the knitted lace formed using the knitted lace fabric can be prevented. Further, in the present invention, by forming a chain stitch structure using a chain stitch yarn different from the insertion yarn, it is not necessary to make the insertion yarn thick in order to leave the chain stitch structure, and the insertion yarn and the chain stitch yarn are made thin. Therefore, the amount per unit volume of the yarn constituting the base portion can be reduced to increase the density difference between the base portion and the handle portion.

  As described above, according to the present invention, by manufacturing a knitted lace using the above-described lace knitted fabric, fraying of the yarn can be prevented, and the density difference of the yarn between the base portion and the handle portion can be increased. It is possible to improve the sheer feeling of the knitted lace, to clarify the pattern, and to suppress the decrease in aesthetic appearance.

FIG. 2 is a knitting structure diagram schematically showing the lace knitted fabric 20 by omitting yarns other than the chain knitting yarn 21 and the thermal bonding yarn 23. The organization chart shown in FIG. 1 and FIG. 2 is schematically shown for easy understanding. In the actual knitted fabric, the curvatures of the first loop-shaped portion 24 and the second loop-shaped portion 25 are small, and the yarns 21, 22, and 23 are in close proximity or in contact with each other. In the present invention, the knitted fabric knitted by each yarn is referred to as a lace knitted fabric 20, and the knitted lace fabric is referred to as a knitted lace.

  The knitted lace fabric 20 has a plurality of through holes, and a lace pattern is formed by the shape and arrangement of the through holes. The knitted lace fabric 20 is formed with a pattern portion having a dense amount of yarn arranged per unit area and a base portion having a sparse amount of yarn arranged per unit area. A pattern is formed by the shape and arrangement of the parts. Such a knitted lace fabric with a pattern is used for women's underwear, for example.

  As shown in FIG. 1, the knitted lace fabric 20 includes a chain knitting yarn 21, a thermal bonding yarn 23, and a covering yarn 22 that is an insertion yarn. The chain knitting yarn 21 may be referred to as a warp yarn or a ground knitting yarn. The thermal bonding yarn 23 is a yarn also called a spandex, and has a lower melting temperature than other yarns used as the lace fabric 20 and has thermoplasticity. The thermal bonding yarn 23 is made of, for example, polyester-based polyurethane having a melting temperature lower than that of the chain stitch yarn 21.

  FIG. 3 is a front view showing a part of the covering yarn 22 before knitting. FIG. 4 is a front view showing a part of the covering yarn 22 knitting the knitted lace fabric 20. The covering yarn 22 has a shape as shown in FIGS. 1 and 2 when the knitted lace fabric 20 is knitted, but FIG. 4 shows a state where the covering yarn 22 is linearly extended for easy understanding. It shows with.

  The covering yarn 22 is a yarn in which a covering yarn 31 is spirally wound around a core yarn 30 having elasticity. The core yarn 30 is a single fiber yarn (filament yarn) made of a thermoplastic synthetic resin, and is made of, for example, polyester polyurethane. The covering yarn 31 is a long fiber yarn (filament yarn) composed of a plurality of long fibers made of synthetic resin, and is made of, for example, polyamide (trade name: nylon).

  In the state before knitting, the covering yarn 22 is covered with a covering yarn 31 so that the core yarn 30 is not exposed as shown in FIG. The covering yarn 22 is knitted in the stretched state as shown in FIG. 4 using the stretchability of the core yarn 30. When the covering yarn 22 is stretched, a spiral gap is formed between the covering yarns 31 and the core yarn 30 is exposed from the gap.

  The covering yarn 22 is a long fiber yarn (filament yarn) composed of a plurality of long fibers made of synthetic resin, and is made of, for example, polyamide (trade name: nylon, rayon, polyester).

  As shown in FIG. 2, the chain knitting yarn 21 is chain knitted to form a first loop-shaped portion 24 and a second loop-shaped portion 25. The first loop-shaped portion 24 and the second loop-shaped portion 25 are formed alternately in a plurality of stages in the course direction C. Here, the first loop portion 24 may be referred to as a needle loop, and the second loop portion 25 may be referred to as a sinker loop. As the first loop-shaped portion 24 and the second loop-shaped portion 25 are alternately connected and extend in the course direction C, the wale 26 is formed. A plurality of the wales 26 are formed side by side in the waling direction W and are connected to each other to form a chain stitch structure, in other words, a chain stitch structure. Further, the chain stitch yarn 21 is appropriately swung to connect the wales 26 adjacent in the wale direction W, thereby forming a chain stitch structure having a fraying prevention function. A portion where the chain yarn 21 swings is referred to as a run stop portion 42.

  Each first loop-shaped portion 24 is generally formed in a U shape, and is arranged substantially side by side in a predetermined course direction C and a wale direction W orthogonal to the course direction C. Further, each first loop-shaped portion 24 opens to the front stage C1 in the course direction which is one side in the course direction. The first loop-shaped portions 24 are aligned in the wale direction W to form a course, and the first loop-shaped portions 24 are aligned in the course direction C to form a wale.

  The second loop-shaped portion 25 connects the first loop-shaped portions 24 arranged in the course direction C. For example, attention is paid to one second loop portion 25a. One end of the second loop-shaped portion 25a to be noticed is connected to the end of the first loop-like portion 24a at the same stage as the second loop-shaped portion 25a to be noticed. The second loop-shaped portion 25a of interest passes through the first loop-shaped portion 24b of the preceding stage C1 in the course direction of the second loop-shaped portion 25a of interest from one side to the other side as it goes from one end to the other end. Extending to the course direction rear stage C2, passing through the first loop part 24a at the same stage as the second loop part 25a of interest from one side to the other side, extending to the rear direction C2 of the course direction, the second loop shape of interest It continues to the end of the first loop-shaped portion 24c of the rear stage C2 of the portion 25a in the course direction. In this way, the loop-shaped portions 24 and 25 are connected in a chain, and a wale 26 extending in the course direction C is formed. Each insertion yarn such as the covering yarn 22 and the thermal bonding yarn 23 is knitted into the wale 26 by being sandwiched between the first loop portion 24 and the second loop portion 25.

  In the present invention, the course direction C is the warp direction of the knitted fabric, and means the lace knitting direction. The wale direction W is a lateral direction of the knitted fabric and means a direction intersecting the lace knitting direction. A plurality of first loop-shaped portions 24 are arranged in the course direction C and the wale direction W. The plurality of first loop portions 24 arranged in the course direction C and the wale direction W are arranged substantially in contact with a predetermined virtual plane. In this case, each knitting yarn knitted into the chain stitch structure such as the covering yarn 22 and the thermal bonding yarn 23 is arranged on one side with respect to the virtual plane.

  In the present invention, a direction in which the insertion threads 22 and 23 are arranged with respect to a virtual plane extending along the first loop-shaped portion 24 is referred to as a front direction Z1, and the virtual plane is set with respect to the insertion threads 22 and 23. The direction in which is arranged is referred to as the back direction Z2. In FIGS. 1 and 2, a direction away from the paper surface in the thickness direction Z perpendicular to the paper surface is a front direction Z1, and a direction away from the paper surface in a direction perpendicular to the paper surface is a back direction Z2.

  On the surface in the front direction Z1 of the knitted lace fabric 20, the first loop-shaped portion 24 is hidden by the knitting yarn such as the covering yarn 22 and the thermal bonding yarn 23. Therefore, the pattern in the front direction Z1 of the knitted knitted fabric 20 and the lace pattern formed on the knitted lace fabric 20 are clearer than the surface in the back direction Z1.

  For example, the notable second loop-shaped portion 25a is inserted in the surface direction Z1 through the first loop-shaped portion 24b of the first stage C1 in the course direction of the second loop-shaped portion 25a, and the second loop-shaped portion 25a is the same in the course direction. The first loop portion 24a of the step is inserted in the back direction Z2, and is continuous with the first loop portion 24c of the rear stage C2 in the course direction.

  The covering yarn 22 is a yarn for forming a lace pattern in the chain stitch structure. The covering yarn 22 is knitted to the wales 26 adjacent in the waling direction W, thereby connecting the two wales 26 adjacent in the waling direction W. As shown in FIG. 1, the covering yarn 22 has a lateral swing portion extending from one wale 26 adjacent to the wale direction W to the other wale 26 and a covering yarn knitting portion knitted into the wale 26. .

  In a space surrounded by the two laterally swinging portions arranged in the course direction C and the wale 26 to which the laterally swinging portions are connected, a through hole that is inserted in the thickness direction of the knitted fabric is formed. The shape and arrangement of the through holes are adjusted by selectively arranging the horizontal swing portion of the covering yarn 22. As a result, a lace pattern represented by the arrangement and shape of the through holes can be formed on the lace fabric 20. Here, the through-hole surrounded by the horizontal swing portion and the wale 26 may be filled with a pattern yarn described later to form a pattern.

  The covering yarn 22 extends in the region in the front direction Z <b> 1 rather than the first loop-shaped portion 24. The covering yarn 22 extends between the first loop portion 24 and the second loop portion 25 set in advance and extends in the wale direction W. In the present embodiment, a plurality of covering yarns 22 are knitted into the chain stitch structure, and each covering yarn 22 is knitted side by side in the wale direction W. The position where each covering yarn 22 is knitted is appropriately selected depending on the lace pattern formed on the knitted lace fabric 20.

  The thermal bonding yarn 23 is realized by a yarn having a melting point temperature lower than that of the chain stitch yarn 21 and the covering yarn 22. In the present embodiment, a yarn that partially melts in a heating state in a heating process performed after knitting of the knitted lace fabric is used. The thermal bonding yarn 23 is used for preventing fraying of the chain knitting yarn 21 and the covering yarn 22 constituting the lace knitted fabric 20. In the present embodiment, the thermal bonding yarn 23 is realized by a non-coated yarn, that is, a bare yarn not covered with a coated yarn, a so-called bear yarn, and is realized by a polyurethane elastic yarn having a melting temperature of about 140 ° C. or more and 190 ° C. or less. The The thermal bonding yarn 23 is knitted into a chain stitch structure in a state of being stretched with respect to a natural state.

  The thermal bonding yarn extends along the wale 26 and is knitted into all the loop-shaped portions constituting the wale 26. Accordingly, in the chain knitting structure, the thermal bonding yarn 23 is knitted on both the base portion where the amount of yarn per unit area is sparse and the pattern portion where the amount of yarn per unit area is denser than the base portion. Is included. In the present embodiment, the knitted lace fabric 20 has a plurality of thermal bonding yarns 23, and each thermal bonding yarn 23 is knitted for each wale 26. Thus, the thermal bonding yarn 23 is knitted over the entire region of the chain stitch structure.

  The thermal bonding yarn 23 extends in the region in the front direction Z1 from the first loop-shaped portion 24 and extends in the region in the back direction Z2 from the second loop-shaped portion 25. The thermal bonding yarn 23 proceeds in a zigzag manner as it proceeds in the course direction C along the corresponding wale 26. For example, when the thermal bonding yarn 23 passes between the first loop-shaped portion 24a and the second loop-shaped portion 25a of interest from the wale direction one W1 to the other wale W2, the course direction of the first loop-shaped portion 24c of interest. It passes between the first loop-like portion 24c and the second loop-like portion 25c of the rear stage C2 from the other wale direction W2 to the wale direction one W1.

  Immediately after knitting, the thermal bonding yarn 23 extends in the region in the front direction Z1 from the first loop-shaped portion 24 and extends in the region in the back direction Z2 of the lace knitted fabric 20 from the covering yarn 22. Therefore, in the region where the thermal bonding yarn 23 and the cover ring yarn 22 are inserted between the same first loop portion 24 and the second loop portion 25, the thermal bonding yarn 23 is covered with the first loop portion 24 and the covering ring 22. Insert between thread 22. The covering yarn 22 is inserted between the thermal bonding yarn 23 and the second loop portion 25. In this case, when the chain knitting yarn 21 is stretched in the course direction C, the curvature radii of the first loop-shaped portion 24 and the second loop-shaped portion 25 are reduced, and the thermal bonding yarn 23 is connected to the covering yarn 22 and the first loop-shaped yarn 21. It arrange | positions between the 1 loop-shaped parts 24, and contacts the covering thread | yarn 22 and the 1st loop-shaped part 24. FIG.

  In the present embodiment, in the region where the thermal bonding yarn 23 and the covering yarn 22 pass between the same first loop portion 24 and the second loop portion 25, the thermal bonding yarn 23 and the covering yarn 22 Cross each other and pass through the first loop-shaped part 24 and the second loop-shaped part 25. Specifically, the thermal bonding yarn 23 has the same first step in the course direction as the first loop portion 24a to be noticed from the side where the first loop portion 24a to be noticed is continuous with the second loop shape portion 25b in the first stage C1 in the course direction. It passes through the second loop portion 25a.

  On the other hand, the covering yarn 22 has a first loop-shaped portion 24a of interest in the course direction and the first loop-shaped portion 24a of interest in the course direction from the side opposite to the side where the first loop-shaped portion 24a is continuous with the second loop-shaped portion 25b of the front stage C1. It passes through the second loop portion 25a of the same stage. In this case, when the knitted lace fabric 20 is stretched in the course direction C, the thermal bonding yarn 23 and the covering yarn 22 approach each other at a portion 31 that passes through the second loop-shaped portion 25 together.

  Further, immediately after the knitting, the covering yarn 22 and the thermal bonding yarn 23 knitted into the chain stitch structure are not completely restrained by the chain stitch structure, so that the covering yarn 22 and the thermal bonding yarn 23 are in contact with each other. Some of the portions may have a portion in which the thermal bonding yarn 23 is not arranged in the front direction Z <b> 1 than the covering yarn 22. Even in this case, most of the plurality of portions where the covering yarn 22 and the thermal bonding yarn 23 come into contact with each other are such that the thermal bonding yarn 23 is arranged in the back direction Z2 with respect to the covering yarn 22.

  Further, multifilaments having a fineness of the chain knitting yarn 21 and the covering yarn 22 of 50 denier or less, particularly 40 denier or less are used. The fineness of the chain knitting yarn 21 is such that it is as thin as possible when it is used as a knitted lace product. For example, it can be realized by various fibers such as nylon (polyamide-based synthetic fiber), rayon, polyester, and polypropylene. Moreover, the various yarns used in this embodiment are merely examples, and other types of yarns may be used.

  Further, a polyurethane elastic yarn having a fineness of the thermal bonding yarn 23 of 10 denier or more and 300 denier or less is used. In addition to the polyurethane elastic yarn, any material having a relatively low melting temperature and thermoplasticity may be used, and may be realized by a polyamide synthetic fiber or the like. Alternatively, a non-stretchable thread may be used as the thermal bonding thread 23.

  The knitted lace fabric 20 of the present embodiment is heated at a temperature equal to or higher than the melting temperature of the thermal bonding yarn 23 after knitting and lower than the melting temperature of the remaining yarns 21 and 22. As a result, a part of the thermal bonding yarn 23 is partially dissolved. A part of the dissolved portion adheres to the adjacent chain knitting yarn 21 and the covering yarn 22. By solidifying in this state, the chain knitting yarn 21 and the covering yarn 22 in contact with the thermal bonding yarn 23 can be prevented from being released from the thermal bonding yarn 23. Further, the yarns 21 and 22 that are in contact with the thermal bonding yarn 23 can be bonded to each other by the thermal bonding yarn 23. As a result, the connected state of each yarn is maintained, and fraying of the yarn can be prevented.

  In this way, the binding of the chain stitch structure is strengthened at the portion where the thermal bonding yarn 23 adheres to another yarn. Specifically, the first loop-shaped portion 24 and the second loop-shaped portion 25 are bonded via the thermal bonding yarn 23. As a result, even if a part of the chain stitch yarn 21 is divided, it is possible to prevent the second loop portion 25 from being released from the first loop portion 24. As a result, the unraveling of the chain knitting yarn 21 is blocked by the bonding portion between the first loop-shaped portion 24 and the second loop-shaped portion 25, and the unraveling of the chain knitting yarn 21 beyond the bonding portion can be prevented.

  As another embodiment, the core yarn 30 of the covering yarn 22 is melted by using a yarn having a melting temperature lower than that of the chain stitch yarn for the core yarn 30 of the covering yarn 22 without using the thermal bonding yarn 23. Thus, the connected state of each yarn may be maintained to prevent fraying of the yarn.

  FIG. 5 is a knitting diagram for explaining prevention of unraveling of the knitted lace 20A of the present embodiment, and FIG. 6 is a knitting diagram showing a knitted lace 10A of a comparative example. A knitted lace 20A according to the present embodiment shown in FIG. 5 is obtained by heating the knitted lace fabric 20 in which the above-described thermal bonding yarn 23 is knitted. Further, the knitted lace 10A of the comparative example shown in FIG. 6 is obtained by heating the knitted lace fabric 20A in which the thermal bonding yarn 23 is not knitted.

  As shown in FIG. 6, in the lace fabric 10 of the comparative example, when the two second loop-shaped portions 25 arranged in the course direction C are cut off at the divided portions 40 and 41, the divided portion 40 of the rear stage C2 in the course direction is the front direction. By being pulled by Z1, the portion where the chain knitting yarn 21 is locked is cut off, and the chain knitting structure is unwound along the course direction rear stage C2 rather than the divided portion 40. In the knitted lace 10A of the comparative example, the unraveling of the chain stitch structure proceeds along the rear stage C2 in the course direction, reaches the run stop portion 42, and the run stop portion 42 suppresses the unwinding. Therefore, in order to shorten the progress of unwinding, it is necessary to increase the run stop portion 42. When the run stop portions 42 are increased, the number of yarns extending in the wale direction W increases, and the sense of sheerness of the knitted lace 10A is impaired. In this case, the wale 26 is divided in the course direction C.

  On the other hand, as shown in FIG. 5, in the knitted lace 20A of the present embodiment, the thermal bonding yarn 23 extends in the course direction C. The two-loop portion 25 is bonded.

  In the knitted lace fabric 20 of the present embodiment, when the two second loop-shaped portions 25 arranged in the course direction C are cut off at the divided portions 40 and 41, the divided portion 40 of the rear stage C2 in the course direction is pulled in the front direction Z1. Even if there is an adhesive portion 44 in which the first loop-shaped portion 24 and the second loop-shaped portion 25 are bonded to each other in the latter half of the course direction C2 than to the divided portion 40 of the latter half of the course direction C2, the bonded portion 44 The unraveling of the chain structure is prevented and further unraveling is prevented. Therefore, it is possible to prevent the chain stitch structure from being unraveled as compared with the knitted lace 10A of the comparative example. Further, since the unraveling is suppressed by the adhesion portions 43 and 44, the run stop portion 42 can be reduced or eliminated, and the sense of sheerness of the knitted lace 20A can be improved as compared with the comparative example. In the present embodiment, the first loop portion 24 and the second loop portion 25 that are the same in the course direction are bonded to each course direction C, so that a part of the second loop portion 25 is divided. Even so, the wale 26 can be prevented from being divided in the course direction C. As described above, in the present embodiment, the thermal bonding yarns 23 are knitted by extending along the wale 26, so that the binding in the course direction C can be increased for the chain stitch structure, and the durability can be improved. it can.

  FIG. 7 is a knitting diagram for explaining fraying of the knitted lace 20A of the present embodiment, and FIG. 8 is a knitting diagram showing a knitted lace 10A of a comparative example. The knitted lace 20A of the present embodiment shown in FIG. 7 is obtained by heating the knitted lace fabric 20 in which the above-described thermal bonding yarn 23 is knitted. Further, the knitted lace 10A of the comparative example shown in FIG. 8 is obtained by heating the knitted lace fabric 20A in which the thermal bonding yarn 23 is not knitted. 7 and 8, the covering yarn 22 is knitted across the plurality of wales 26.

  As shown in FIG. 8, in the knitted lace 10A of the comparative example, when the covering yarn 22 was cut off at the divided portion 45, the covering yarn 22 exceeded one or more wales 26 than the divided portion 45 in the covering yarn 22. When the portion 46 of the one side W1 in the wale direction is pulled to the one side W1 in the wale direction, the divided portion 45 passes through the wale 26 and the covering yarn 22 comes out of the knitted lace 10A. For example, the covering yarn 22 is prevented from moving by the frictional force with the chain knitting yarn 21, and therefore, when the large force is applied, the covering yarn 22 is displaced from the knitted portion or falls off. May end up.

  On the other hand, as shown in FIG. 7, in the knitted lace 20 </ b> A of the present embodiment, the thermal bonding yarn 23 is knitted into each wale 26, so that the covering yarn 22 is provided for each wale by the first loop-shaped portion 24. And adhered to the second loop-shaped portion 25.

  In the knitted lace 20A of the present embodiment, when the covering yarn 22 is cut off at the divided portion 45, one of the covering yarns 22 in the wale direction W1 exceeding the one or more wales 26 than the divided portion 45. Even if the portion 46 is pulled in one direction W1 in the wale direction, the adhesive portions 47 and 48 of the covering yarn 22 and the wale 26 are bonded to prevent the divided portion 45 from coming out of the wale 26. This prevents the covering yarn 22 from being displaced. As described above, in the present embodiment, the covering yarn 22 is fixed to the chain stitch structure by the adhesive force of the thermal bonding yarn 23, so that the covering yarn 22 can be prevented from shifting and falling off.

  Further, the wales 26 adjacent to the waling direction W are bonded to each other via the covering yarn 22, so that the waling direction W interval between the adjacent wales 26 is prevented from expanding or narrowing, It is possible to prevent the lace pattern of the knitted lace 20A from being disturbed.

  As described above, according to the present embodiment, fraying of each yarn constituting the knitted lace 20A can be prevented. For example, fraying of the yarn caused by the manufacturing state such as sewing or cutting of the knitted lace 20A, and fraying of the yarn caused by the use state such as wearing or washing can be prevented, and the quality can be improved.

  Further, when the chain stitch structure is formed using the thermal bonding yarn 23, the thermal bonding yarn 23 must be thickened to leave the chain stitch structure even after the lace knitted fabric is heated, and the unit volume constituting the base portion. The amount of yarn per hit increases, and the density difference between the base portion and the handle portion becomes small. Further, the knitted lace fabric 20 itself becomes hard and is difficult to deform.

  On the other hand, in the present embodiment, a chain knitting structure is formed using a chain knitting yarn 21 different from the thermal bonding yarn 23, and a yarn having heat resistance is used as the chain knitting yarn 21. The overall form of 20 can be stabilized. Further, the chain stitch yarn 21 and the thermal bonding yarn 23 can be made thin. As a result, the number of yarns constituting the ground portion can be reduced, and the density difference between the ground portion and the handle portion can be increased. As a result, the sense of sheerness can be improved and the pattern can be made clear with respect to the knitted lace fabric 20 and the knitted lace fabric 20A that is obtained by heating the lace knitted fabric 20. In addition, the melting amount of the thermal bonding yarn 23 can be reduced, and the influence of the melted portion on the entire lace fabric 20 can be reduced to prevent the pattern from being damaged. Further, since the chain knitting yarn 21 can be made thinner, the knitted lace 20A can be made soft, in other words, easily deformed. Thus, for example, the knitted lace 20A can be suitably used as a fabric such as underwear.

  Further, according to the present embodiment, the thermal bonding yarn 23 is a bare yarn whose surface portion has heat melting property. Therefore, when the knitted lace fabric 20 is heated, the portion of the thermal bonding yarn 23 that contacts the chain knitting yarn 21 melts and adheres to the chain knitting yarn 21. Further, the portion of the thermal bonding yarn 23 that contacts the covering yarn 22 melts and adheres to the covering yarn 22. As described above, according to the present embodiment, the exposed portion of the thermal bonding yarn 23 that directly contacts the other yarn becomes a portion that adheres to the other yarn, so that the thermal bonding yarn 23 is attached to the other yarn. The adhesion amount to adhere can be increased and the adhesive force can be improved. Therefore, fraying of each yarn can be more reliably prevented.

  Further, by realizing the thermal bonding yarn 23 with a non-coated yarn, that is, a bare yarn that is not covered with a coated yarn, the amount of yarn in the base portion can be further reduced, and the yarn density difference between the base portion and the handle portion is reduced. Can be increased, the sense of sheerness of the knitted lace fabric 20 can be improved, and the pattern can be made clear.

  Further, according to the present embodiment, since the thermal bonding yarn 23 is knitted over the entire region of the chain stitch structure, fraying of the yarn in the entire knitted lace 20A can be prevented. For example, even if the knitted lace 20A is sewn or cut at an arbitrary position, it is possible to prevent the yarn from fraying from the sewing portion and the cutting portion.

  In addition, since fraying of the yarn over the entire knitted lace 20 can be prevented, the motif cut for cutting the knitted lace 20A at an arbitrary position can also prevent fraying of the cut portion and can be applied to a wide lace. It becomes possible. Moreover, since fraying over the entire knitted lace fabric 20 can be prevented, the knitted lace fabric can also be used for a part of the outerwear that requires durability. As described above, according to the present embodiment, fraying of the yarn can be prevented over the entire knitted lace, so that the usage application can be expanded.

  Further, according to the present embodiment, the thermal bonding yarn 23 and the covering yarn 22 are knitted into the chain stitch structure by inserting between the first loop-shaped portion 24 and the second loop-shaped portion 25. In the knitted lace fabric 20, the surface on the side where the first loop-shaped portion 24 is arranged is the back surface with respect to the covering yarn 22 knitted into the chain stitch structure, and the opposite surface is the front surface. Become. In the present embodiment, the covering yarn 22 is arranged in the front direction Z1 with respect to the portion where the thermal bonding yarn 23 and the covering yarn 22 are knitted in common. Therefore, when the knitted lace 20 </ b> A is viewed from the front surface, the covering yarn 22 hides the thermal bonding yarn 23 and the first loop-shaped portion 24.

  In this manner, the thermal bonding yarn 23 can be hidden by the covering yarn 22, and the thermal bonding yarn 23 can be made difficult to see from the front surface. As a result, the pattern formed on the knitted lace 20A can be clarified. Even if the thermal bonding yarn 23 is melted, the influence on the pattern viewed from the front surface can be reduced. Further, the thermal bonding yarn 23 passes between the first loop-shaped portion 24 and the covering yarn 22, whereby the first loop-shaped portion 24 and the covering yarn 22 can be bonded to each other. Can be prevented from leaving the chain structure.

  In the present embodiment, in the region where the thermal bonding yarn 23 and the covering yarn 22 are inserted between the same first loop portion 24 and the second loop portion 25, the thermal bonding yarn 23 and the covering yarn 22. Pass through the loop-shaped portion 25 in different directions. In this case, by pulling the knitted lace fabric 20 in the wale direction W, regions surrounded by the thermal bonding yarn 23 and the covering yarn 22 are close to each other in the wale direction W, so that the thermal bonding yarn 23 and the covering yarn 22 Thus, an approaching portion 34 is produced in which the first loop-like portion 24 and the second loop-like portion 25 approach each other. By heating the knitted lace fabric 20 while being pulled in the wale direction W in this way, a part of the thermal bonding yarn 23 can be melted at the approaching portion 34, and the thermal bonding yarn 23, the covering yarn 22, the first The adhesive force for bonding the loop-shaped portion 24 and the second loop-shaped portion 25 can be increased.

  In the present embodiment, the fineness of the thermal bonding yarn 23 is set to 10 denier or more and 300 denier or less, and the chain knitting yarn is set to 20 denier or more and 70 denier or less. If the thermal bonding yarn is less than 10 denier, all of the thermal bonding yarn of the knitted lace may be melted, and even if a part of the thermal bonding yarn is melted, the amount of adhesion between the other yarn and the thermal bonding yarn May be insufficient. In this case, fraying of the yarn may occur. Also, if the thermal bonding yarn exceeds 300 denier, the thermal bonding yarn reduces the density difference between the base portion and the handle portion, which reduces the feeling of knitting lace and the aesthetics. . Also, the knitted lace becomes stiff. On the other hand, in the present invention, by setting the thermal bonding yarn to 10 denier or more and 300 denier or less, fraying of the yarn can be eliminated and a decrease in aesthetics can be suppressed. In addition, the thermal bonding yarn can further suppress a decrease in aesthetics by being 70 denier or less.

  FIG. 9 is a side view showing a knitting portion of a back jacquard raschel knitting machine 60 for knitting the knitted lace fabric 20 of the first embodiment. The knitted lace fabric 20 can be knitted by, for example, a back jacquard raschel knitting machine. A back jacquard raschel knitting machine 60 (hereinafter simply referred to as a knitting machine 60) introduces a chain knitting yarn 21, a covering yarn 22, and a thermal bonding yarn 23 toward a knitting position 73 provided in the vicinity of a knitting needle 72. Have means. In the present embodiment, the yarn introduction means for introducing the thermal bonding yarn 23 toward the knitting position 73 is arranged behind the knitting machine rather than the yarn introduction means for introducing the covering yarn 22 toward the knitting position 73. The Here, the back of the knitting machine is a direction from the back surface of the knitting needle 72 toward the hook portion.

  Specifically, the yarn introduction means included in the knitting machine is realized by a thermal bonding yarn ridge 61, jacquard bars 62 and 63, a plurality of handle ridges 64, and a ground rod 65. The chain knitting yarn 21 is threaded through the ground yarn 65, the covering yarn 22 is threaded through the jacquard bars 62 and 63, and the thermal bonding yarn 23 is threaded through the thermal bonding yarn rod 61. Further, when pattern yarns, which are yarns for forming a pattern, are knitted into the wale 26, the pattern yarns are passed through a plurality of pattern ridges 64. Hereinafter, a case where a pattern yarn is knitted in addition to the thermal bonding yarn 23 and the covering yarn 22 will be described.

  Each of the yarn introduction means 61 to 65 is arranged radially toward the knitting position 73 where the knitting needle 72 captures the chain knitting yarn 21, and on the rear side of the knitting machine in the direction in which the knitting needle 72 captures the chain knitting yarn 21. As it goes, it is arranged in the order of the ground rod 65, the plurality of handle rods 64, the jacquard bars 62 and 63, and the thermal bonding yarn rod 61. Accordingly, the yarns are arranged on the rear side of the knitting machine from a predetermined knitting position in the order of the chain knitting yarn 21, the plurality of pattern yarns, the covering yarn 22 and the thermal bonding yarn 23.

  A plurality of knitting needles 72 are formed side by side in a direction perpendicular to the longitudinal direction of the knitting machine, and are fixed to a needle bar 69 serving as a holding means for holding each knitting needle 72. The needle bar 69 moves the knitting needles 72 up and down. Further, the needle bar 69 is operated, and each yarn introduced to each yarn introduction means 61 to 65 is introduced to a predetermined knitting position.

  The respective yarn introduction means 61 to 65 move the respective yarns corresponding to the knitting needles 72 in the space behind the knitting machine in the direction in which the knitting needles 72 are arranged in synchronization with the up and down movement of the knitting needles 72. An overlap (knitting knitting motion) to be performed and an underwrapping (insertion motion) to move each yarn corresponding to the knitting needle 72 in the space in front of the knitting machine in the direction in which the knitting needles 72 are arranged are performed. In addition to these wrapping motions, a so-called swing (swinging motion) that moves in a direction perpendicular to the direction in which the knitting needles 72 are arranged is performed. Specifically, there are two swing operations.

  In the swing-in (back swing) operation that is the first swing operation, each yarn corresponding to the space in front of the knitting machine is moved from the space behind the knitting machine to the knitting needle 72 through the side of the knitting needle 72. . In the swing-out (front swing) operation that is the second swing operation, each yarn corresponding to the space behind the knitting machine moves from the space in front of the knitting machine to the knitting needle 72 through the side of the knitting needle 72. . When the guides attached to the yarn introduction means 61 to 65 are operated, the corresponding yarns pass around the knitting needle 72 according to a predetermined path, and a knitted fabric including the corresponding yarns is formed.

  The knitting unit 73 includes a stitch comb bar 71, a trick plate bar 68 and a tong bar 70. The tong bar 70 has a plurality of tongs corresponding to each knitting needle at the tip. The knitting machine 60 knits the lace fabric 20 described above by the operations of the yarn introduction means 61 to 65 and the needle bar 69. Then, the knitted lace fabric 20 knitted by the knitting assisting action of the stitch comb bar 71 is auxiliary knitted, passed through the trick plate bar 68, and the knitted lace fabric 20 is wound up by the winding portion provided in the vicinity of the knitting portion. .

  FIG. 10 is a cross-sectional view schematically illustrating the movement of the knitting needle 72 and the ground rope 66 of the chain knitting portion 26, and the chain knitting yarn 21 of FIG. 10 (1) to FIG. 10 (5) in this order. The knitting work of the chain knitted portion 26 proceeds. In the knitting needle 72, a hook portion 50 for locking the chain knitting yarn 21 is formed at a distal end portion, and a knitting needle stem 51 is formed at a proximal end portion. A tong 52 for opening and closing an opening formed by the hook portion 50 is formed at the tip of the tongue bar 70. The knitting needle 72 and the tongue 52 are formed so as to be individually movable up and down with respect to the ground 65. Only the knitting of the wale 26 will be described first with reference to FIG. 10, and the covering yarn 22 and the thermal bonding yarn 23 knitted into the wale 26 will be described later.

  As shown in FIG. 10 (1), the hook portion 50 hooks a new first loop-shaped portion 24j formed by the chain knitting yarn 21 in a state where the ground rope 65 is disposed in front of the knitting needle 72, and 52 closes the opening of the hook portion 50. Next, as shown in FIG. 10 (2), the knitting needle 72 rises toward the ground 65 with respect to the tongue 52. As a result, the opening of the hook portion 50 is opened, and the first loop-shaped portion 24j of the chain knitting yarn 21 hooked by the hook portion 50 comes out of the hook portion 50 and moves to the knitting needle stem 51.

  Next, as shown in FIG. 10 (3), the ground cloth 65 backswings with respect to the knitting needle 72. Next, the ground 65 overlaps and further performs a front swing. As a result, the chain knitting yarn 21 guided to the ground cloth 65 moves so as to wind the knitting needle 72, thereby forming a new first loop-shaped portion 24k. The new first loop portion 24k is hooked by the hook portion 50. Next, as shown in FIG. 10 (4), the tongue 52 rises toward the hook portion 50 and closes the opening of the hook portion 50. At this time, the knitting needle 72 is formed with an old first loop-shaped portion 24j formed on the knitting needle stem 51 and a new first loop-shaped portion 24k to which the hook portion 50 is locked.

  Next, as shown in FIG. 10 (5), when the knitting needle 72 and the tongue 52 are lowered, the old first loop-shaped portion 24j pulls out the knitting needle 72 and moves to the trick plate 53 side. Then, in a state where the ground cloth 65 is disposed in front of the knitting needle 72, the hook portion 50 hooks a new first loop-shaped portion 24k formed by the chain knitting yarn 21, and the state is almost the same as that in FIG. . Then, by repeating the operation cycle shown in FIG. 10 (1) to FIG. 10 (5), the first loop-shaped portion 24 is sequentially formed and the first loop-shaped portions 24j, 24k are connected to each other. A wale 26 is formed in which two loop portions 25j are sequentially formed. In the present embodiment, the plurality of whales 26 are connected in the wale direction W by appropriately underwrapping the ground 65. The knitted lace fabric 20 of the present embodiment can be knitted by knitting insertion yarns such as the covering yarn 22 and the thermal bonding yarn 23 into the wales 26 while performing the knitting operation of the wales 26.

  FIG. 11 is a cross-sectional view schematically illustrating the movement of the jacquard bar 62 and the thermal bonding yarn ridge 61, and the operation proceeds in the order of FIGS. 11 (1) to 11 (3). 11 (1) corresponds to FIG. 10 (3), FIG. 11 (2) corresponds to FIG. 10 (4), and FIG. 11 (3) corresponds to FIG. 10 (5), respectively. It is a figure which adds and shows the thread collar 61. FIG. As described above, in the knitting machine 60, the jacquard bars 62 and 63 are arranged on the rear side of the knitting machine rather than the ground cloth 65 for introducing the chain knitting yarn. Further, a thermal bonding yarn ridge 61 serving as a thermal bonding yarn ridge is arranged behind the knitting machine rather than the jacquard bars 62 and 63.

  11 (1) and 11 (3), in the state where the ground bar 66 is disposed behind the knitting machine with respect to the knitting needle 72, the jacquard bar 62 and the thermal bonding yarn barb 61 are also knitted needles 72. Is arranged behind the knitting machine. Further, as shown in FIG. 11 (2), in a state where the ground bar 66 is disposed in front of the knitting machine with respect to the knitting needle 72, the jacquard bar 62 and the thermal bonding yarn barb 61 are also disposed in front of the knitting needle 72. The

  Further, as shown in FIG. 11 (2), the jacquard bar 62 and the thermal bonding yarn ridge 61 are provided with the thermal bonding yarn 23 and the cover that are guided by underlapping in the state where the ground ridge 66 is backswinged. The ring yarn 22 straddles the chain stitch yarn 21. In this state, when a new loop is formed by the chain knitting yarn 21, the thermal bonding yarn 23 and the covering yarn 22 are knitted into the loop. As described above, the thermal bonding yarn hook 61 and the jacquard bar 62 operate in synchronization with the swing movement of the ground hook 66.

  The jacquard bar 62 is arranged in front of the knitting machine with respect to the heat-bonding yarn ridge 61. As a result, when the thermal bonding yarn 23 and the covering yarn 22 are knitted into the chain knitting portion 26 formed by the ground 66, the thermal bonding yarn 23 guided to the knitting position is guided to the knitting position. The covering yarn 22 is located behind the knitting machine rather than the covering yarn 22, and the covering yarn 22 is positioned on the surface side of the lace fabric 20 with respect to the thermal bonding yarn 23.

  FIG. 12 is a structure diagram schematically showing the S region in FIG. 2, FIG. 12 (1) shows a structure diagram of the chain knitting yarn 21, and FIG. 12 (2) shows a structure diagram of the thermal bonding yarn 23. .

  For example, the knitting needle 72 at an arbitrary position is the first knitting needle 72a, the knitting needle 72 adjacent to the first knitting needle 72a in the wale direction one W1 is the second knitting needle 72b, and the second knitting needle 72b is in the wale direction one W1. The adjacent knitting needle 72 is defined as a third knitting needle 72c. The distance between the first knitting needle 72a and the knitting needle 72 arranged in the other W2 in the wale direction with respect to the first knitting needle 72a is defined as the first knitting needle interval L1, and the distance between the first knitting needle 72a and the second knitting needle 72b. The distance between the second knitting needles L2 is set, and the interval between the second knitting needles 72b and the third knitting needles 72c is set as the third knitting needle distance L3. An interval between the second knitting needles L4 is defined as an interval between the second knitting needles 72 and 72.

  The ground cloth 65 for introducing each chain knitting yarn 21 performs the same knitting operation on each chain knitting yarn 21. In the first course C1, the description will be focused on the chain knitting yarn guide for hooking the chain knitting yarn 21 onto the second knitting needle 72b, and the description of the remaining chain knitting yarn guide will be omitted.

  As shown in FIG. 12 (1), in the first course C1, the chain knitting yarn guide of interest backswings between the third knitting needles L3, overlaps and front swings through the second knitting needles L2. In the second course C2, the chain knitting yarn guide of interest backswings between the second knitting needles L2, overlaps, and front swings through the second knitting needles L2.

  In the third course C3, the chain knitting yarn guide of interest underlaps the fourth knitting needle interval L4, backswings the fourth knitting needle interval L4, overlaps, and front swings through the third knitting needle interval L3. In the fourth course C4, the chain knitting yarn guide of interest performs a back swing through the third inter-knitting needle L3, overlaps, and performs a front swing through the fourth inter-knitting needle L4. In the fifth course C5, the chain knitting yarn guide of interest backswings the fourth inter-knitting needle L4, overlaps, and front swings through the third inter-knitting needle L3.

  The sixth course C6 performs the same operation as the fourth course C4, and the seventh course C7 performs the same operation as the fifth course C5. In the eighth course C8, the chain knitting yarn guide of interest underlaps the fourth inter-knitting needle L4, backswings the fourth inter-knitting needle L4, overlaps, and front swings through the third inter-knitting needle L3. In the ninth course C9, the chain knitting yarn guide of interest underlaps the second knitting needle interval L2, backswings the second knitting needle interval L2, overlaps, and front swings through the third knitting needle interval L3.

  In this way, the ground cloth 65 repeatedly performs the operation of hooking the predetermined chain knitting yarn 21 on each knitting needle 72 in each course using the guide provided for each chain knitting yarn 21. Thereby, the chain knitting portion 26 extending in a chain shape can be formed. In the present embodiment, the knitting machine 60 appropriately underwraps the chain knitting yarn 21 on the knitting needle 72 in each course. As a result, the second loop-shaped portion 25 can be swung in one direction W1 in the wale direction and the other direction W2 in the wale direction, and the wale 26 adjacent in the wale direction W is connected to form a chain stitch structure having a fraying prevention function. be able to.

  The thermal bonding yarn 23 performs a swing operation in synchronization with the ground 65 by the thermal bonding yarn hook 61. The thermal bonding yarn ridge 61 that guides each thermal bonding yarn 23 performs the same knitting operation on each thermal bonding yarn 23. In the first course C1, the thermal bonding yarn guide for positioning the thermal bonding yarn 23 between the second knitting needles L3 will be described with attention, and the description of the remaining thermal bonding yarn guide will be omitted.

  As shown in FIG. 12 (2), in the first course C1, the noted thermal bonding yarn guide underlaps the second knitting needle interval L2 and reaches the third knitting needle interval L3. In the second course C2, the third knitting needle interval L3 is under-wrapped and reaches the second knitting needle interval L2. The thermal bonding yarn guide of interest repeats the operations of the first course C1 and the second course in order from the second course C2. As described above, the thermal bonding yarn 23 reciprocates between the two adjacent knitting needles by the thermal bonding yarn 61 in synchronism with the swinging movement of the ground 65.

  For the insertion yarn other than the thermal bonding yarn, for example, the covering yarn 22, the jacquard bar 62 repeats the underlap for a predetermined distance and direction at a predetermined position in synchronization with the swing operation of the ground 65. Similarly, with respect to the handle yarn, the handle rod 64 repeats the underlap for a predetermined distance and direction at a predetermined position in synchronization with the swing operation of the ground rod 65.

  Thus, the knitted lace fabric portion formed in the S region is formed by the knitting operation of the heat-bonding yarn ridge 61, the jacquard bars 62 and 63, the plurality of handle ridges 64, the ground rod 65, and the knitting needle 72. Can do. The knitting machine 60 is arranged in the order of the ground hook 65, the covering yarn hooks 62, 63, and the thermal bonding yarn hook 61 in the order toward the rear of the knitting machine, so that the covering yarn 22 is more than the thermal bonding yarn 23. The knitted lace fabric 20 of the present embodiment shown in FIGS. 1 and 2 can be formed.

  FIG. 13 is a flowchart showing the manufacturing procedure of the knitted lace product. First, when the pattern of the knitted lace to be knitted is determined in step s0, the process proceeds to step s1. In step s1, the chain knitting yarn 21, the covering yarn 22, the thermal bonding yarn 23, and the pattern yarn are prepared, and an operation program of each yarn introduction means of the knitting machine 60 is input so that the pattern determined in step s0 is obtained. . Next, the knitting machine 60 is operated. Accordingly, the knitted lace fabric 20 having a desired pattern can be knitted. When the knitting work of the knitted lace fabric 20 is completed, the process proceeds to step s2.

  In step s2, the knitted lace fabric 20 knitted in step s1 is dyed. When the dyeing is completed, the process proceeds to step s3. In step s3, in order to prepare the lace fabric 20, the lace fabric 20 is heated to a predetermined temperature. At this time, the lace fabric 20 is heated while being pulled in the wale direction W. As a result, the knitted lace fabric 20 is prepared, and a part of the thermal bonding yarn 23 described above melts and adheres to other adjacent yarns. The knitted lace 20A is formed by heating the knitted lace fabric 20 at a predetermined temperature for a predetermined time, and the process proceeds to step s4. In the present embodiment, the knitted lace fabric 20 is prepared by maintaining the temperature at 150 to 160 ° C. for 60 seconds. In the knitted lace 20A, since the lace fabric 20A is heated, a part of the thermal bonding yarn 23 is fixed to another yarn.

  The knitted lace thus manufactured is molded by a mold at a heating temperature of 180 ° C., for example, in order to obtain a required three-dimensional shape such as a female underwear.

  In step s4, the knitted lace 20A after molding is cut and divided into individual processed products, and the processed product of the cut knitted lace 20A is sewn to manufacture a knitted lace product, thereby manufacturing the knitted lace product. Then, it progresses to step s5 and complete | finishes an operation | work.

  At the time of the cutting and sewing process in step s5, since a part of the thermal bonding yarn 23 is fixed to another yarn, the binding of the chain stitch structure is strengthened. Accordingly, the yarns are prevented from fraying at the time of cutting or sewing, and the yield of the manufactured knitted lace product can be improved and the quality can be improved. In addition, since the knitted lace product produced has a stronger chain stitch structure, fraying due to use such as wearing or washing can be suppressed, and the durability of the knitted lace product can be improved. In the heating step shown in step s3, the covering yarn 22 and the thermal bonding yarn 23 come close to the loop-like portions 24 and 25 by heating the knitted lace fabric in the wale direction W. As a result, the loop-like portions 24 and 25 and the covering yarn 22 can be firmly bonded by the thermal bonding yarn 23.

  FIG. 14 is a knitting organization chart schematically showing a part of a knitted lace fabric 20B according to the second embodiment of the present invention. The knitted lace fabric 20B of the second embodiment differs from the lace knitted fabric 20 of the first embodiment in the direction in which the thermal bonding yarn 23 passes through the second loop-shaped portion 25, and the other configurations are the same. Therefore, about the structure similar to the lace fabric 20 of 1st Embodiment, the same referential mark is attached | subjected and description is abbreviate | omitted.

  In the present embodiment, the thermal bonding yarn 23 passes through the second loop-shaped portion 25 in the same direction as the covering yarn 22 and is inserted between the first loop-shaped portion 24 and the covering yarn 22. Specifically, the thermal bonding yarn 23 and the covering yarn 22 are the first loop shape of interest from the side opposite to the side where the first loop-like portion 24a of interest is continuous with the second loop-like portion 25b of the front stage C1 in the course direction. It passes through the second loop-shaped portion 25a that is the same as the course direction of the portion 24a.

  In this way, the thermal bonding yarn 23 passes through the second loop-shaped portion 25 in the same direction as the covering yarn 22, so that the contact portion between the covering yarn 22 and the thermal bonding yarn 23 can be increased, and the thermal bonding yarn It is possible to improve the adhesive force at which the cover 23 bonds the covering yarn 22. As a result, fraying of the covering yarn 22 can be prevented more reliably.

  As another embodiment, the thermal bonding yarn 23 and the covering yarn 22 are the first loop-shaped portion of interest from the side where the first loop-like portion 24a of interest is continuous with the second loop-like portion 25b of the course front stage C1. The case where it passes through the second loop-like portion 25a in the same course direction as 24a is also included in the present invention.

  The thermal bonding yarn 23 has a second loop shape that is the same step as the first loop-shaped portion 24a in the course direction from the side where the first loop-shaped portion 24a of interest is continuous with the second loop-shaped portion 25b of the preceding stage C1 in the course direction. The covering yarn 22 passes through the portion 25a, and the covering yarn 22 is connected to the first loop-shaped portion 24a of interest and the course from the side opposite to the side where the first loop-shaped portion 24a of interest is continuous with the second loop-shaped portion 25b of the front stage C1 in the course direction. A case of passing through the second loop-shaped portion 25a having the same direction is also included in the present invention.

  FIG. 15 is a knitting organization chart schematically showing a part of a knitted lace fabric 20C according to the third embodiment of the present invention. FIG. 14 is a knitting structure diagram schematically showing the lace knitted fabric 20C by omitting yarns other than the chain knitting yarn 21, the thermal bonding yarn 23, and the stretch yarn 27. The knitted lace fabric 20C of the third embodiment is further knitted with a stretchable elastic yarn 27 separately from the thermal bonding yarn 23 as compared to the lace knitted fabric 20 of the first embodiment. It is the same. Therefore, about the structure similar to the lace fabric 20 of 1st Embodiment, the same referential mark is attached | subjected and description is abbreviate | omitted.

  In the lace knitted fabric 20C of the third embodiment, the stretch knitted fabric 27C is knitted in the stretched state separately from the thermal bonding yarn 23, so that the knitted lace knitted fabric 20C contracts. Thereby, elasticity can be given to the knitted lace fabric 20C. For example, polyurethane elastic yarn, so-called spandex, is used as the stretch yarn.

  The elastic yarn 27 extends on the first loop-shaped portion 24 side from the covering yarn 22. The stretchable yarn 27 and the thermal bonding yarn 23 pass through the second loop-shaped portion 25 in the same direction and are knitted into the chain stitch structure. In other words, the thermal bonding yarn 23 extends and is knitted in the same manner as the stretchable yarn 27. The stretchable yarn 27 is knitted into each wale 26 and passes in a zigzag as it advances in the course direction C along the wale 26.

  In the present embodiment, the stretchable yarn 27 and the thermal bonding yarn 23 have the first loop-shaped portion 24a of interest from the side where the first loop-shaped portion 24a of interest is continuous with the second loop-shaped portion 25b of the preceding stage C1 in the course direction. It passes through the second loop-shaped portion 25a of the same step in the course direction. Further, the covering yarn has a first loop-shaped portion 24a to be noticed from the side opposite to the side where the first loop-shaped portion 24a is connected to the second loop-shaped portion 25b of the preceding stage C1 in the course direction. It passes through the loop portion 25a. Therefore, the stretchable yarn 27 and the thermal bonding yarn 23 intersect the covering yarn 22 at a portion where the stretchable yarn 27, the thermal bonding yarn 23 and the covering yarn 22 all pass through the same loop.

  Even when the thermal bonding yarn 23 is knitted into the knitted lace fabric 20C as in the third embodiment, the same effect as in the first embodiment can be obtained. That is, the thermal bonding yarn 23 can prevent fraying of each yarn by bonding other yarns. Further, by bonding the covering yarn 22 and the chain stitch yarn 21 with the thermal bonding yarn 23, it is possible to prevent the so-called span loss that the thermal bonding yarn 23 comes out of the chain stitch structure.

  Further, in the third embodiment, by pulling the knitted lace fabric 20 in the wale direction W, the regions surrounded by the stretchable yarn 27 and the covering yarn 22 are close to each other in the wale direction W, and the thermal bonding yarn 23 and the cover The ring yarn 22, the elastic yarn 27, the first loop portion 24, and the approach portion 34 where the second loop portion 25 approaches each other are generated. By heating the knitted lace fabric 20 while being pulled in the wale direction W in this manner, a part of the thermal bonding yarn 23 can be melted at the approaching portion 34, and the thermal bonding yarn 23, the stretch yarn 27, the covering yarn 22, The adhesive force which adhere | attaches the 1st loop-shaped part 24 and the 2nd loop-shaped part 25 can be heightened. Further, in the third embodiment, the stretchable yarn 27 and the thermal bonding yarn 23 extend in the same direction, so that the contact portion where the thermal bonding yarn 23 contacts the stretchable yarn 27 can be increased, and the stretchable yarn 27 is pulled out. This can be prevented more reliably.

  In addition, the knitted lace fabric 20 </ b> C shown in FIG. When the stretchable yarn 27 and the thermal bonding yarn 23 advance in the same direction and are knitted into the loop-shaped portion, the stretchable yarn 27 and the thermal bonding yarn 23 run in parallel, so that the thermal bonding yarn 23 expands and contracts. There are cases where the second loop portion 25 is disposed on the side of the yarn 27 compared to the yarn 27. The thermal bonding yarn 23 may be arranged side by side with the stretchable yarn 27 in the thickness direction Z. As described above, the positional relationship between the stretchable yarn 27 and the thermal bonding yarn 23 becomes random, so that the thermal bonding yarn 23 may be disposed between the covering yarn 22 and the stretchable yarn 27. As a result, the covering yarn 22 and the stretchable yarn 27 can be bonded together, and the chain stitch yarn 21 and the stretchable yarn 27 can be bonded together.

  FIG. 17 is a knitting organization diagram schematically showing a part of a knitted lace fabric 20D according to the fourth embodiment of the present invention. FIG. 18 is a knitting structure diagram schematically showing the lace knitted fabric 20D by omitting yarns other than the chain knitting yarn 21, the thermal bonding yarn 23, and the stretch yarn 27. The knitted lace fabric 20D of the fourth embodiment is further knitted with a stretchable yarn 27 having elasticity, in addition to the thermal bonding yarn 23, as compared with the lace knitted fabric 20B of the second embodiment. It is the same. Therefore, about the structure similar to the lace fabric of 1st Embodiment, the same referential mark is attached | subjected and description is abbreviate | omitted.

  In the knitted lace fabric 20D of the fourth embodiment, the stretch knitted fabric 27 is knitted in the stretched state separately from the thermal bonding yarn 23, so that the knitted lace fabric 20D contracts. Thereby, elasticity can be given to the knitted lace fabric 20D. For example, polyurethane elastic yarn, so-called spandex, is used as the stretch yarn.

  The elastic yarn 27 extends on the first loop-shaped portion 24 side from the covering yarn 22. The stretchable yarn 27 and the thermal bonding yarn 23 pass through the second loop-shaped portion 25 in the intersecting direction and are knitted into the chain stitch structure. In other words, the thermal bonding yarn 23 extends and is knitted in a direction different from the stretchable yarn 27. The stretchable yarn 27 is knitted into each wale 26 and passes in a zigzag as it advances in the course direction C along the wale 26.

  In the present embodiment, the stretchable yarn 27 has the same loop direction as the first loop-shaped portion 24a of interest from the side where the first loop-shaped portion 24a of interest is continuous with the second loop-shaped portion 25b of the first stage 1 in the course direction. It passes through the second loop portion 25a. Further, the covering yarn 22 and the thermal bonding yarn 23 are arranged such that the first loop-shaped portion 24a to be noticed and the first loop-shaped portion 24a to be noticed from the side opposite to the side where the second loop-shaped portion 25b of the preceding stage C1 in the course direction is connected. It passes through the second loop portion 25a of the same direction. Therefore, the stretchable yarn 27 intersects the thermal bond yarn 23 and the covering yarn 22 in a portion where the stretchable yarn 27, the thermal bonding yarn 23, and the covering yarn 22 all pass through the same loop.

  Even when the thermal bonding yarn 23 is knitted into the knitted lace fabric 20D as in the fourth embodiment, the same effect as in the first embodiment can be obtained. That is, the thermal bonding yarn 23 can prevent fraying of each yarn by bonding other yarns. Further, by bonding the covering yarn 22 and the chain stitch yarn 21 with the thermal bonding yarn 23, it is possible to prevent the so-called span loss that the thermal bonding yarn 23 comes out of the chain stitch structure.

  In the fourth embodiment, by pulling the knitted lace fabric 20 in the wale direction W, the region surrounded by the stretchable yarn 27 and the covering yarn 22 is close to the wale direction W so that the thermal bonding yarn 23 and the cover The ring yarn 22, the elastic yarn 27, the first loop portion 24, and the approach portion 34 where the second loop portion 25 approaches each other are generated. By heating the knitted lace fabric 20 while being pulled in the wale direction W in this manner, a part of the thermal bonding yarn 23 can be melted at the approaching portion 34, and the thermal bonding yarn 23, the stretch yarn 27, the covering yarn 22, The adhesive force which adhere | attaches the 1st loop-shaped part 24 and the 2nd loop-shaped part 25 can be heightened.

  In the present embodiment, since the covering yarn 22 and the thermal bonding yarn 23 extend in the same direction, the contact portion where the thermal bonding yarn 23 contacts the covering yarn 22 can be increased, and the covering yarn 22 comes off. This can be prevented more reliably. Further, since the thermal bonding yarn 23 and the stretchable yarn 27 cross each other, the thermal bonding yarn 23 is bonded to the stretchable yarn 27, and the restraining portion that restrains the stretchable yarn 27 can be reduced. Accordingly, it is possible to prevent the span from being lost while suppressing a decrease in the stretchability of the knitted lace fabric.

  FIG. 19 is a knitting organization chart schematically showing a part of a knitted lace fabric 20E according to the fifth embodiment of the present invention. The knitted lace fabric 20D of the fifth embodiment differs from the lace knitted fabric 20B of the fourth embodiment in the direction in which the stretchable yarn 27 extends, and the other configurations are the same. In the present embodiment, the stretchable yarn 27 has a first loop-shaped portion 24a of interest and the course direction of the first loop-shaped portion 24a of interest from the side opposite to the side where the first loop-shaped portion 24a of interest is continuous with the second loop-shaped portion 25b of the preceding stage C1 in the course direction. It passes through the second loop portion 25a of the same stage. Therefore, when all of the stretchable yarn 27, the covering yarn 22 and the thermal bonding yarn 23 pass through the same second loop-shaped portion 25, they pass in the same direction. In the portion where the stretchable yarn 27, the covering yarn 22 and the contact bonding yarn 23 all pass through the same second loop-shaped portion, the respective yarns 22, 23 and 27 are located in close proximity. Therefore, when the thermal bonding yarn 23 is melted, the adhesive force between the covering yarn 22 and the stretchable yarn 27 can be increased.

  FIG. 20 is a side view showing a knitting portion of a back jacquard raschel knitting machine 60C for knitting the knitted lace fabrics 20C to 20E of the third to fifth embodiments. In the knitting machine 60, an elastic yarn hook 66 serving as a yarn introduction means for introducing the elastic yarn 27 toward the knitting position 73 is disposed between the jacquard bar 62 and the thermal bonding yarn bar 61. The other configuration is the same as that of the knitting machine shown in FIG.

  By arranging the elastic yarn hook 66 and the thermal bonding yarn rod 61 in this way, the elastic yarn hook 66 and the thermal bonding yarn rod 61 are arranged behind the covering yarn 22. Accordingly, when the lace knitted fabric 20C is viewed from the front side, the stretch yarn 27 and the thermal bonding yarn 23 are hidden by the covering yarn 22. As a result, the pattern of the lace fabric can be clarified. Further, the knitted lace fabrics 20C to 20D shown in the third to fifth embodiments can be knitted by making the operations of the jacquard bars 62 and 63, the elastic yarn hook 66 and the thermal bonding yarn hook 61 different. In addition, the front and rear sides of the elastic yarn folds and the thermal bonding yarn folds may be reversed. In this case, in the knitted lace fabrics of the third to fifth embodiments, the stretchable yarn and the thermal bonding yarn are upside down. Even when the upper and lower sides of the stretchable yarn and the thermal bonding yarn are interchanged, they are included in the present invention. In addition to the above-mentioned back jacquard knitting machine, lace knitted fabric knitted by a front jacquard knitting machine in which jacquard bars 62 and 63 are arranged in front of the knitting machine with respect to the pattern yarn is also knitted with thermal adhesive yarn. Are included in the present invention.

  As mentioned above, even if it is the lace fabric of 2nd-5th embodiment, the effect similar to 1st Embodiment can be acquired. The above-described embodiment of the present invention is merely an example of the invention, and the configuration can be changed within the scope of the invention. For example, in the present embodiment, the thermal bonding yarn 23 and the covering yarn 22 are knitted into the chain stitch structure having a fray prevention function, but the base knitted fabric only needs to be formed in the chain stitch. It is not limited to the chain stitch structure described above. For example, the same effect can be obtained even if the second loop-shaped portion of the chain knitting yarn 21 is a chain knitting structure in which the second loop-shaped part does not swing, that is, a chain knitting structure having no fraying prevention effect. In addition to the basic chain stitch structure, the base knitted fabric may be a tulle knitted fabric or a power net structure. By forming the power net structure, it is possible to form a clear pattern with elasticity in multiple directions. Further, the knitted fabric as a basis may be a wide lace (all over lace) and a narrow lace.

  In this embodiment, the insertion thread is a covering thread, but the present invention is not limited to this. Further, the insertion yarn may be a pattern yarn or a floating yarn. Further, the thermal bonding yarn 23 does not have to be knitted in all the chain knitted portions, and may be knitted in the chain knitted portions at intervals in the wale direction W. As described above, the lace knitted fabric structure shown in the above-described embodiment is merely an example, and the knitted fabric structure as a foundation, the knitting method of each insertion yarn, the chain knitting yarn, and the types of each insertion yarn are appropriately selected. It is possible to change. The thermal bonding yarn 23 is an uncoated yarn, but may be realized by a covering yarn composed of a core yarn and a coated yarn.
