Description

  The present invention relates to a knitted lace having a thick portion for preventing unwinding of a yarn from a cut surface and sewing or thermocompression after cutting.

  A conventional knitted lace is described in Patent Document 1, for example. This prior art knitted lace has a portion into which an insertion yarn having a melting temperature lower than that of a chain knitting yarn is knitted, and in the chain knitting structure, a first loop portion and a second loop portion are alternately arranged. The second loop-shaped part of interest extends through the first loop-shaped part before the wale direction of the second loop-shaped part and extends toward the rear stage of the wale direction, and The second loop-shaped part is formed in a chain by passing through the first loop-shaped part at the same stage in the wale direction and connected to the first loop-shaped part at the latter stage in the wale direction, and extends in the wale direction.

  The insertion yarn has stretchability, and the insertion yarn is a covering yarn in which a covering yarn is spirally wound around a core yarn having stretchability and heat melting property. Each of the covering yarns is formed by connecting a plurality of loop-shaped portions and knitted in a stretched state between wales adjacent to each other in the course direction perpendicular to the wale direction to form a spiral gap between the coated yarns. The core yarn is exposed from this gap.

  By heating such a knitted lace 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, the chain knitting yarn in contact with the insertion yarn is prevented from being released from the insertion yarn, and the chain knitting yarn is adhered to each other by the insertion yarn, thereby maintaining the connected state of the chain knitting yarn. Is prevented.

  In the prior art described in Patent Document 1, when a knitted lace is used as a fabric, a plurality of cut parts are joined together by sewing or thermocompression bonding using an adhesive resin or other methods, and clothing such as women's underwear is used. When manufactured, the stitches of each part are sewn into the chain stitch structure through the needle thread of the sewing machine, but stitches are likely to occur in the stitches due to the effects of lace holes, etc. In order to prevent product defects and a decrease in the strength of the seam, it is necessary to carry out sewing by turning back the seam, and to prevent the unsealing of the end of the seam or the finished surface of the seam.

  In addition, in the case of thermocompression bonding with an adhesive resin, the adhesive softened by heating is cured in a state of exuding from the fabric, and the cured adhesive may come into contact with the skin of the wearer and cause skin damage. There is a problem that the feeling is bad.

  An object of the present invention is to provide a knitted lace that can prevent the thread from being unwound from the cut surface, and can prevent the strength of the seam from being lowered during sewing and bleeding of the adhesive during thermocompression bonding.

The present invention is a knitted lace used for a fabric to be cut,
An adhesive chain stitch yarn constituting a chain stitch structure in which a wale in which needle loops and sinker loops are alternately arranged forms a plurality of rows;
A first insertion yarn that is knitted alternately into the sinker loop of one of the two wales adjacent to each other and the sinker loop of the other of the two wales to form a thick portion;
The first course of the predetermined first is alternately knitted into a sinker loop of a central wale of three adjacent wales and a sinker loop of a wale adjacent to one side of the central wale, and A thin second portion is formed by alternately braiding the central whale sinker loop of the second predetermined course other than the first course and the whale sinker loop adjacent to the other side of the central wale. A second insertion thread,
The adhesive chain knitting yarn and the first insertion yarn are bonded to each other,
The adhesive chain knitting yarn and the second insertion yarn are knitted laces bonded to each other.

  The present invention is characterized in that a hole is formed between the first course and the second course so that the second insertion thread does not swing.

  In the present invention, the adhesive chain knitting yarn is composed of a heat-adhesive composite yarn having elasticity.

  In the present invention, the first insertion yarn is composed of a composite yarn having elasticity.

  In the present invention, the second insertion yarn is composed of a composite yarn having elasticity.

  According to the present invention, the first insertion yarns are alternately knitted into the sinker loop of one of the two wales adjacent to each other in the chain stitch structure and the sinker loop of the other of the two wales. The thick part is formed. In addition, the first course of the chain stitch structure is alternately knitted into the central whale sinker loop of the three adjacent wales and the whale sinker loop adjacent to one side of the central wale. Rare and pre-determined second course other than the first course is alternately knitted into a central whale sinker loop and a whale sinker loop adjacent to the other side of the central wale, Composed.

  In such a thick portion, the adhesive chain knitting yarn and the first insertion yarn are bonded to each other, and in the thin portion, the adhesive chain knitting yarn and the second insertion yarn are bonded to each other. The thick part can be used for sewing or thermocompression bonding. In addition, since the first insertion yarn and the adhesive chain knitting yarn are bonded, and the second insertion yarn and the adhesive chain knitting yarn are bonded, high tensile strength is obtained in both the course direction and the wale direction. Strength can be obtained, and the occurrence of unraveling can be prevented without being limited to the cutting direction of the knitted lace. This prevents misalignment between the adhesive chain knitting yarn and the first insertion yarn and misalignment between the adhesive chain knitting yarn and the second insertion yarn, and prevents distortion of the lattice caused by these misalignment. It is.

  Further, according to the present invention, since a hole is provided between the predetermined first course and the predetermined second course, high air permeability and design freedom such as a design can be obtained.

  In addition, according to the present invention, it is not necessary to fold the cloth to make it thicker in order to reinforce the sewing part or thermocompression bonding part by sewing or thermocompression bonding or to prevent the resin from leaking out. It is possible to finish the crimping part thinly, and it becomes stress-free for the wearer of the product, and it is possible to make it difficult to bring out a sewing or thermocompression line to the outer.

  According to the present invention, since the first insertion yarn is composed of a composite yarn having stretchability, it is possible to easily realize a thick portion having stretchability not only in the longitudinal direction but also in the lateral direction.

  Further, according to the present invention, since the second insertion yarn is composed of a composite yarn having stretchability, it is possible to easily realize a thin portion having stretchability not only in the longitudinal direction but also in the lateral direction.

  FIG. 1 is a knitting organization chart of a knitting lace 1 according to an embodiment of the present invention, FIG. 2 is an knitting organization chart in which a thick portion 2 of the knitting lace 1 is enlarged, and FIG. 3 shows a thin portion 3 of the knitting lace 1. It is the expanded organization chart. 1 to 3, in order to facilitate illustration, the curvatures of the needle loop 24 and the sinker loop 25 are increased, and the chain knitting yarn 21, the first insertion yarn 22, and the second insertion, which are adhesive chain knitting yarns. The yarn 23 is shown schematically separated.

  The knitted lace 1 of the present embodiment includes a thick part 2 and a thin part 3 connected to the thick part 2. Although the thick portion 2 and the thin portion 3 are not shown in the drawing, one or both of the first insertion yarn 22 and the second insertion yarn 23 are knitted in a horizontal direction and connected to each other. The knitted lace 1 is manufactured as a knitted lace before cutting by being heated in a heat setting process. As shown in FIG. 2, the thick portion 2 includes a sinker loop 25 of any one of the two wales 26 adjacent to each other, and a sinker loop 25 of any one of the two adjacent wales 26. Are inserted alternately, and the first insertion yarn 22 knitted into the chain stitch structure constituted by the chain stitch yarn 21 is provided.

  As shown in FIG. 3, the thin portion 3 is adjacent to the sinker loop 25 of the central wale 26 b of the three adjacent wales of the first course C <b> 1 determined in advance and one side of the central wale 26. The sinker loop 25 of the wale 26 is alternately inserted and adjacent to the other side of the sinker loop 25 of the center wale 26b and the center wale 26 of a predetermined second course C2 other than the first course C1. The second insertion yarns 23 are alternately inserted through the sinker loops 25 of the wale 26c and knitted into the chain stitch structure.

  The chain knitting structure has chain knitting yarns 21 in which needle loops 24 and sinker loops 25 are alternately connected to form a chain stitch structure wale 26. The chain knitting yarn 21 is also called a ground knitting yarn. The wales 26 may be swayed as appropriate, and the wales 26 may be connected in the course direction.

  The knitted lace 1 is formed with a plurality of holes, and depending on the shape and arrangement of the holes, the amount of yarn arranged per unit area is dense and the amount of yarn arranged per unit area A base pattern having a sparse pattern is formed, and a pattern is formed by the shape and arrangement of the pattern section and the base section. Such a knitted lace 1 with a patterned pattern is used for women's underwear, for example.

  The first insertion yarn 22 and the second insertion yarn 23 are composite yarns of a core yarn having elasticity and a covering yarn. The core yarn is made of polyurethane, for example. The coated yarn 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).

  The first insertion yarn 22 and the second insertion yarn 23 are covered with a covering yarn so that the core yarn is not exposed before knitting. The first insertion yarn 22 and the second insertion yarn 23 are knitted in an expanded state using the stretchability of the core yarn. When the first insertion yarn 22 and the second insertion yarn 23 are stretched, a gap is formed between the covered yarns, and the core yarn is exposed from the gap.

  The chain knitting yarn 21 is chain knitted to form a needle loop 24 and a sinker loop 25. The needle loop 24 and the sinker loop 25 are formed in a plurality of stages in an alternating manner. The needle loop 24 and the sinker loop 25 are alternately connected to form a wale 26. The wales 26 are formed in a plurality of rows 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, when the chain stitch yarn 21 is suitably swung to connect the wales 26 adjacent to each other in the wale direction W, a chain knitting structure having a function of preventing unraveling is formed. A portion where the chain stitch yarn 21 swings is referred to as a run stop portion 42.

  Each needle loop 24 is generally formed in a U shape, and is arranged side by side in the wale direction W and the course direction C orthogonal to the wale direction W. Each needle loop 24 opens to the front in the course direction, which is one side in the course direction.

  Each sinker loop 25 connects the needle loops 24 arranged in the course direction C. For example, pay attention to one sinker loop 25. The sinker loop 25 of interest has one end connected to the end of the needle loop 24 at the same stage as the sinker loop 25 of interest. The focused sinker loop 25 extends from the one side to the other side of the focused sinker loop 25a as it goes from one end to the other end, extends from one side to the other side, and extends to the rear in the course direction. The needle loop 24 at the same stage as the sinker loop 25 is inserted from one side to the other side and extends to the rear stage in the course direction, and is connected to the end of the needle loop 24 at the rear stage in the course direction of the sinker loop 25 of interest.

  In this way, the loops 24 and 25 are connected in a chain, and a wale 26 extending in the course direction C is formed. Each insertion thread such as the first insertion thread 22 and the second insertion thread 23 is knitted into the wale 26 by being sandwiched between the needle loop 24 and the sinker loop 25.

  In the present embodiment, 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 needle loops 24 are arranged in the course direction C and the wale direction W. The plurality of needle loops 24 arranged in the course direction C and the wale direction W are arranged along a predetermined virtual plane. In this case, each knitting yarn knitted into the chain stitch structure such as the first insertion yarn 22 and the second insertion yarn 23 is arranged on one side with respect to the virtual plane.

  In the present embodiment, a direction in which the insertion threads 22 and 23 are arranged with respect to a virtual plane extending along the needle loop 24 is referred to as a front direction, and a direction in which the virtual plane is arranged with respect to the insertion threads 22 and 23. Is referred to as the reverse direction. In FIG. 1 and FIG. 2, among the thickness directions perpendicular to the paper surface, the direction away from the paper surface is the front direction, and among the directions perpendicular to the paper surface, the direction away from the paper surface is the back direction.

  The needle loop 24 is hidden on the surface in the front direction of the knitted lace 1 by knitting yarns such as the first insertion yarn 22 and the second insertion yarn 23. Therefore, the surface pattern of the knitted lace 1 and the lace pattern formed on the knitted lace 1 are clearer than the surface in the reverse direction.

  For example, the focused sinker loop 25 is inserted through the needle loop 24 at the front stage in the course direction of the sinker loop 25 in the front direction, and is inserted through the needle loop 24 at the same stage in the course direction of the sinker loop 25 in the course direction. It continues to the needle loop 24 at the rear stage.

  The first insertion yarn 22 is a yarn for forming a lace pattern in the chain stitch structure. The first insertion yarns 22 are knitted into the wales 26 adjacent in the wale direction W, thereby connecting the two wales 26 adjacent in the wale direction W. As shown in FIG. 2, the first insertion yarn 22 has a lateral swing portion extending from one wale 26 adjacent to the wale direction W to the other wale 26, and an insertion 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 hole 30 that is inserted in the thickness direction of the knitted fabric is formed. The shape and arrangement of the holes 30 are adjusted by selectively arranging the laterally swinging portions of the first insertion thread 22 and the second insertion thread 23. As a result, a lace pattern represented by the arrangement and shape of the holes 30 can be formed on the knitted lace 1. Here, the hole 30 surrounded by the laterally swinging portion and the wale 26 may be filled with a later-described handle yarn to form a handle pattern.

  In a state before knitting, the chain knitting yarn 21 is covered with the covering yarn so that the covering yarns are in contact with each other and the core yarn is not exposed. The chain knitting yarn 21 is knitted in an expanded state using the stretchability of the core yarn. When the chain knitting yarn 21 is stretched, a spiral gap is formed between the covered yarns, and the core yarn is exposed from the gap. The core yarn of the chain knitting yarn 21 and the covering yarn of the first and second insertion yarns 22 and 23 are both made of polyurethane, but are made of different types of polyurethane, and the first and second insertion yarns 22 and 23 are made of polyurethane. The melting temperature of the core yarn of the chain knitting yarn 21 is lower than the melting temperature of. The melting temperature of the core yarn is lower than the melting temperatures of the coated yarn and the first and second insertion yarns 22 and 23 and has thermoplasticity. Thus, the chain stitch yarn 21 is a yarn including a core yarn made of a material having a low melting temperature.

  As the core yarn of the chain knitting yarn, a thermoplastic polyurethane elastic yarn having a denier of 10 to 300 denier, preferably 10 to 50 denier is used. Further, heat treatment is performed at a heating temperature of 170 ° C. or higher and 195 ° C. or lower for a heating time of 30 seconds or longer and 90 seconds or shorter. This melts the core yarn and prevents the remaining yarn from changing its characteristics. For example, when the heating time is constant, if the heating temperature is less than 170 ° C., the adhesive force due to the melted core yarn is reduced. On the other hand, when the heating temperature exceeds 195 ° C., it becomes difficult to maintain the form as the core yarn, and the characteristics of the yarn other than the core yarn may change. On the other hand, in this embodiment, it can prevent that the problem mentioned above arises by making heating temperature into 170 degreeC or more and 195 degrees C or less as mentioned above.

  The thinner the core yarn is, the smaller the adhesion portion becomes closer to the point contact, and the texture becomes better. The thicker the core yarn, the larger the adhesion portion and the texture is impaired. In order to make the core yarn thicker and maintain a good texture, it is conceivable to make the covering yarn thicker, but the chain knitting yarn 21 becomes thicker and the sense of sheerness of the lace knitted fabric is impaired. Further, the thinner the core yarn, the lower the strength, and the thicker the yarn, the higher the strength. Therefore, when the core yarn is a thin yarn of less than 10 denier, there is a problem that the strength is too small, and when the core yarn is a thick yarn of more than 300 denier, the texture is impaired. By making the core yarn 10 denier or more and 300 denier or less, there is no shortage in strength and a good texture can be obtained. From the same viewpoint, the core yarn is preferably 10 denier or more and 50 denier or less.

  Since the core yarn of the first and second insertion yarns 22 and 23 has heat melting properties, when the lace knitted fabric is heated, the portion of the insertion yarn that contacts the core yarn of the chain knitting yarn 21 melts. Adhering to the chain stitch yarn 21. As described above, according to the present embodiment, the exposed portion of the first and second insertion yarns 22 and 23 that comes into contact with the core yarn of the chain knitting yarn 21 becomes a portion that adheres to the chain knitting yarn 21, and further the chain. Since the core yarn of the knitting yarn 21 has adhesiveness, the amount of adhesion between the first and second insertion yarns 22, 23 and the core yarn of the chain knitting yarn 21 can be increased, and the adhesive force can be improved. Therefore, the unraveling of each yarn can be prevented more reliably.

  FIG. 4 is a side view showing the knitting portion of the back jacquard raschel knitting machine 60 for knitting the knitted lace 1. The knitted lace 1 can be knitted by the back jacquard raschel knitting machine 60, for example. A back jacquard raschel knitting machine (hereinafter sometimes simply referred to as “knitting machine”) 60 is provided on a knitting portion 73 provided with a chain knitting yarn 21, a first insertion yarn 22, and a second insertion yarn 23 in the vicinity of a knitting needle 72. There is a yarn introduction means for introducing the yarn toward the yarn. 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 an insertion 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 thread 65, the first insertion thread 22 and the second insertion thread 23 are threaded through the jacquard bars 62 and 63, and the elastic polyurethane thread is threaded through the insertion thread collar 61. The 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, the case where the pattern yarn is knitted in addition to the second insertion yarn 23 and the first insertion yarn 22 will be described.

  Such yarn introduction means are arranged in a radial manner toward the knitting portion 73 where the knitting needle 72 captures the chain knitting yarn 21, and as the knitting needle 72 moves toward the rear of the knitting machine in the direction of capturing the chain knitting yarn 21. A ground rod 65, a plurality of handle rods 64, jacquard bars 62 and 63, and an insertion yarn rod 61 are arranged in this order. 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, a plurality of pattern yarns, the first insertion yarn 22 and the second insertion yarn 23, and the elastic polyurethane yarn.

  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 to guide each yarn introduced to each yarn introduction means to a predetermined knitting position.

  Each yarn introduction means overlaps each corresponding yarn in the space behind the knitting machine in the direction in which the knitting needles 72 are arranged in synchronism with the vertical movement of the knitting needle 72. (Knitting knitting motion) and underwrapping (insertion motion) in which each yarn corresponding to the knitting needle 72 in the space in front of the knitting machine is moved in the direction in which the knitting needles 72 are arranged. 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. . By operating the guides attached to the respective yarn introduction means, 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 perforations 30 do not have insertion yarns that oscillate each other with respect to the two rows of chain stitches, and are inserted into the respective chain stitches or from the two rows of chain stitches to the chain stitches of the other wales 26. Thus, the hole 30 having an arbitrary shape can be formed by eliminating the transition of the insertion yarn between the two rows of chain stitches where the hole 30 is to be formed.

  The knitting unit 73 includes a stitch comb bar 71, a trick plate bar 68 and a tong bar 70. The tongue bar 70 is formed with a plurality of tongues 52 corresponding to the knitting needles 72 at the tip. The knitting machine 60 knits the knitted lace 1 described above by the operation of the yarn introduction means and the needle bar 69. Then, the knitted lace 1 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 1 is wound up by a winding portion provided in the vicinity of the knitting portion.

  FIG. 5 is a cross-sectional view schematically illustrating the movement of the knitting needle 72 and the ground cloth 65 in the chain knitting portion, and the chain of the chain knitting yarn 21 in the order of FIGS. 5 (1) to 5 (5). The knitting work of the knitting part 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. First, only the knitting of the wale 26 will be described with reference to FIG. 5, and the first insertion yarn 22 and the second insertion yarn 23 knitted into the wale 26 will be described later.

  As shown in FIG. 5 (1), the hook portion 50 hooks a new needle loop 24j formed by the chain knitting yarn 21 and the tongue 52 is hooked in a state where the ground rope 65 is disposed in front of the knitting needle 72. The opening of the part 50 is closed. Next, as shown in FIG. 5B, 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 needle loop 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. 5 (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 needle loop 24k. The new needle loop 24k is hooked by the hook portion 50. Next, as shown in FIG. 5 (4), the tongue 52 rises toward the hook portion 50 and closes the opening of the hook portion 50. At this time, on the knitting needle 72, an old needle loop 24j formed on the knitting needle stem 51 and a new needle loop 24k to which the hook portion 50 is locked are formed.

  Next, as shown in FIG. 5 (5), when the knitting needle 72 and the tongue 52 are both lowered, the old needle loop 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 needle loop 24k formed by the chain knitting yarn 21, and the state is almost the same as in FIG. Then, by repeating the operation cycle shown in FIGS. 5 (1) to 5 (5), the needle loops 24 are sequentially formed, and the wale 26 connected by the needle loops 24j and 24k and the sinker loop 25j. Are sequentially formed. In the present embodiment, the plurality of whales 26 are connected in the wale direction W when the ground 65 is appropriately under-wrapped. The knitting race 1 of the present embodiment can be knitted by knitting insertion yarns such as the first insertion yarn 22 and the second insertion yarn 23 into the wale 26 while performing the knitting operation of the wale 26. .

  FIG. 6 is a cross-sectional view schematically illustrating the movement of the jacquard bar 62 and the insertion thread rod 61, and the operation proceeds in the order of FIGS. 6 (1) to 6 (3). 6 (1) corresponds to FIG. 5 (3), FIG. 6 (2) corresponds to FIG. 5 (4), and FIG. 6 (3) corresponds to FIG. 5 (5), respectively. 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, the insertion yarn hook 61 serving as the elastic yarn hook is disposed behind the knitting machine rather than the jacquard bars 62 and 63.

  6 (1) and 6 (3), in a state where the ground bar 65 is disposed behind the knitting machine with respect to the knitting needle 72, the jacquard bar 62 and the insertion thread barb 61 are also attached to the knitting needle 72. On the other hand, it is arranged behind the knitting machine. Further, as shown in FIG. 6 (2), in a state where the ground bar 65 is arranged in front of the knitting machine with respect to the knitting needle 72, the jacquard bar 62 and the insertion yarn hook 61 are also arranged in front of the knitting needle 72. .

  Further, as shown in FIG. 6 (2), the jacquard bar 62 and the insertion yarn hook 61 are underwrapped in a state in which the ground hook 65 is backswinged, whereby the second insertion yarn 23 and the second insertion yarn 23 are introduced. One insertion yarn 22 straddles the chain stitch yarn 21. In this state, when a new loop is formed with the chain stitch yarn 21, the second insertion yarn 23 and the first insertion yarn 22 are knitted into the loop. In this way, the insertion yarn hook 61 and the jacquard bar 62 operate in synchronization with the swing movement of the ground hook 65.

  The jacquard bar 62 is disposed in front of the knitting machine with respect to the insertion yarn ridge 61. As a result, when the second insertion yarn 23 and the first insertion yarn 22 are knitted in the chain knitting portion formed by the ground cloth 65, the second insertion yarn 23 guided to the knitting position is guided to the knitting position. The first insertion yarn 22 to be threaded is disposed behind the knitting machine, and the first insertion yarn 22 is positioned closer to the surface side of the knitting lace 1 than the second insertion yarn 23.

  As described above, the thick insertion portion 2 is formed by knitting the first insertion yarn 22 in the chain stitch structure, and the needle loop 24 of the wale 26 on one side of the chain stitch structure and the needle loop 24 of the central wale 26 are formed. The second course C2 other than the predetermined first course C1 is inserted alternately into the predetermined first course C1 and is inserted into the needle loop 24 of the second wale 26 and the needle loop 24 of the central wale 26. Since the second insertion thread 23 is alternately inserted into the thin portion 3, the thin portion 3 can be sewn or thermo-compressed using the thick portion of the cut fabric, and the strength of the seam during sewing is reduced and thermo-compression is performed. It is possible to prevent bleeding of the adhesive at the time.

  Moreover, since the hole 30 is provided between the predetermined first course C1 and the predetermined second course C2, it is possible to obtain a high degree of design freedom such as high air permeability and design.

  In addition, since the first insertion thread 22 is made of a stretchable thread, it is possible to easily realize a thick part having stretchability not only in the longitudinal direction but also in the lateral direction.

  In addition, since the second insertion thread 23 is made of stretchable yarn, a thin portion having stretchability not only in the longitudinal direction but also in the lateral direction can be easily realized.

  The knitted lace 1 of the present embodiment can realize the prevention of see-through of the delicate part of the underwear, the reinforcement of the collar circumference, cuffs, the waist part, the under part, and the like by the same method as the thick part 2 described above. Further, the thick portion 2 may be formed using a yarn made of a material other than the second insertion yarn 23 described above, for example, a pattern yarn constituting a motif.

  The thick portion of the above-described embodiment has a knitted structure in which the insertion yarn reciprocates between adjacent chain knitting, but is only an example, and as shown in FIGS. The knitting structure of each other can be changed depending on the intended use and the desired fabric thickness.

  FIG. 7 is a knitting organization chart in which a part of the thick portion 2A of the knitted lace according to another embodiment of the present invention is enlarged. As another embodiment of the present invention, the thick portion 2 described above may be realized by a thick portion 2A formed by a thin knitted fabric in which only one first insertion yarn 22 is swung horizontally between two adjacent rows of wales.

  FIG. 8 is a knitting organization chart in which a part of the thick portion 2B of the knitted lace according to another embodiment of the present invention is enlarged. As still another embodiment of the present invention, the above-described thick portion 2 is realized by a thick portion 2B formed by thick ground knitting in which the first and second insertion yarns 22 and 23 overlap each other between two adjacent rows of wales and are swung. May be.

  FIG. 9 is a knitting structure chart in which a part of the thick portion 2C of the knitted lace according to another embodiment of the present invention is enlarged. As still another embodiment of the present invention, the above-described thick portion 2 has the first insertion yarn 22 swinging between two adjacent rows of wales, and the second insertion yarn 23 between three adjacent rows of wales. It may be realized by the thick portion 2 </ b> C formed by the superposed thick thick knitting.

  FIG. 10 is a knitting organization chart in which a part of the thick portion 2D of the knitted lace according to another embodiment of the present invention is enlarged. As still another embodiment of the present invention, the thick section 2 includes the first insertion yarns 22 that oscillate between the adjacent two rows of whales and between the adjacent three rows of wales, and adjacent two rows. It may be realized by the thick portion 2D by the superposed thick ground knitting in which the second insertion yarns 23 are swung across the wales and between the adjacent three wales.

  By using the above thick portions 2A to 2D, the thick portion 2 can be configured with different patterns, and with various lace patterns, the strength of the stitches is reduced during sewing and the adhesive oozes out during thermocompression bonding. No fabric can be realized.

  The above-described embodiment is merely an example of the present invention, and the configuration can be changed. For example, the material of each thread | yarn 21-23 can be changed suitably. For example, in the case of using free cut, the use of a composite yarn using an adhesive core yarn for the insertion yarn 22 or 23 to further increase the adhesive strength of each yarn, or the use of a single material yarn to reduce the cost. May be. Further, it may be a stretch lace in which polyurethane yarn for expansion / contraction is separately added at the time of lace knitting.

  FIG. 11 is a diagram illustrating an example of a cutting pattern of shorts using the knitted lace 1. A cutting pattern is appropriately arranged on the lace fabric at the design stage, and it is knitted into a panel shape by the above-described method. The portion A shown is the thick portion 2 shown in FIG. 1, and the portion B shown is the thin portion 3 shown in FIG. After scouring, dyeing, and setting process, cutting is performed along the outline shown in FIG. 10, and A1 and A2 are sewn or thermocompression bonded to A3 and A4, respectively, and a shorts shape is completed. As described above, the A part is composed of the thick part 2 in which the first insertion yarn 22 is knitted into the chain stitch structure, and the B part is composed of the needle loop 24 of the wale 26 on one side of the chain stitch structure and the central wale 26. The needle loop 24 is alternately inserted in a predetermined first course C1, and the needle loop 24 of the other side wale 26 and the needle loop 24 of the central wale 26 are other than the predetermined first course C1. Since the second course C2 consists of thin portions 3 through which the second insertion threads 23 are alternately inserted, the A portions of the thick portion 2 of the cut fabric are sewn without causing the yarn to be unwound from the cut surface. Alternatively, even when thermocompression bonding is performed, it is possible to prevent the strength of the seam from being reduced during sewing and the adhesive to ooze out during thermocompression bonding.

  Each of the above-described embodiments is merely an example of the present invention as a cutting pattern, and may be changed to a pattern intended to complete a final product such as a brassiere, a camisole, or an outer.
