Abstract

[Problem] To provide knitted lace that is beautiful and has a good texture. [Solution] Bonding of first contacts 50 between chain stitch yarns 21 and first inserted yarns 23 and of second contacts between chain stitch yarns 21 and second inserted yarns 22 prevents distortion of the openwork. As a result, a beautiful knitted lace is obtained and the beauty thereof can be maintained over long periods. Moreover, since adhesion due to thermofusion of the chain stitch yarns 21, the first inserted yarns 23 and the second inserted yarns 22 that are knitted into the knitted lace 20 as a whole is used, visual and tactile uniformity is obtained and beauty and texture are not adversely affected. Furthermore, elasticity and flexibility are not adversely affected as when all of the first and second contacts 50, 55 are bonded. Thus, an elastic knitted lace 20 that is beautiful and has excellent texture is obtained.

[Problems to be Solved by the Invention] In the above prior art, the chain knitting yarn and the insertion yarn are formed in the contact portion to prevent the yarn from being scattered, etc., but there is a problem that it is perpendicular to the direction of the weft. In terms of the tensile force in the direction of the circle, the strength is lower, and a sufficient anti-scattering effect cannot be obtained. Accordingly, it is an object of the present invention to provide a lace woven fabric which is aesthetically pleasing and has a good texture. [Technical means for solving the problem] The present invention is a lace knitted fabric comprising: a chain knitting yarn, which constitutes a chain knitting structure in which a plurality of annular portions are connected in the weft direction and a plurality of rows are formed in the warp direction. The first insert yarn, which has elastic stretchability, is inserted into each of the loop portions of the chain knitting yarn in the weft direction, and is knitted into the chain knitting structure to impart a weft direction to the chain knitting structure. And a second insertion yarn which is elastically stretchable and stretchable, and which is wound around each annular portion of the chain knitting yarn constituting one chain knitting structure, and knitted with the one chain Each of the annular portions of the chain knitting yarn which is arranged in the chain knitted fabric adjacent to the direction of the ring imparts flexibility to the warp direction of each of the chain knitted fabrics; the first insert yarn is attached to each loop of the chain knitting yarn The position where the portion is in contact with the chain knitting yarn is followed by the second insertion yarn being in contact with each of the loop portions of the chain knitting yarn, followed by the chain knitting yarn. Further, the chain knitting yarn and the second insertion yarn according to the present invention are characterized in that they comprise a composite yarn of a core yarn and a coated yarn, and the core yarn comprises a single fiber yarn of a thermofusible synthetic resin, and the coated yarn comprises A long-fiber yarn made of a heat-meltable synthetic resin having a melting temperature higher than that of a core yarn. Further, the first insertion yarn of the present invention is characterized in that it comprises an elastic yarn of a heat-fusible synthetic resin fiber yarn having a melting temperature higher than that of a core yarn of a chain knitting yarn and having a fineness of 40 denier or more and 420 denier or less. Further, the chain knitting yarn and the second insertion yarn of the present invention are characterized in that they have an elastic yarn having a fineness of 10 denier or more and 280 denier or less. Advantageous Effects of Invention According to the present invention, the first insertion yarn and the chain knitting yarn are followed by the plurality of first contact portions, and the second insertion yarn and the chain knitting yarn are joined to the plurality of second contact portions. A higher tensile strength can be obtained for either the weft direction and the warp direction, and the generation of the skein can be prevented regardless of the cutting direction of the lace woven fabric. Thereby, the positional deviation of the chain knitting yarn and the first insertion yarn and the positional deviation of the chain knitting yarn and the second insertion yarn can be prevented, and deformation of the lattice due to the positional displacement can be prevented. Therefore, even if an external force caused by a manufacturing process such as sewing or cutting of the lace knitted fabric is exerted by an external force caused by wearing or washing, the deformation of the lattice can be prevented, and excellent aesthetics can be maintained for a long period of time. Further, the knitting yarn woven into the entire lace knit fabric and the first insertion yarn are followed by the chain knitting yarn and the second insertion yarn, thereby achieving uniformity in visual and tactile sense without damaging the appearance. A lace fabric that maintains stretchability and has a good texture is obtained by texture. Here, "texture" means a touch, and a good texture means a soft touch. In this way, a lace woven fabric having a high aesthetic appearance and a high texture and high stretchability can be obtained. Moreover, according to the present invention, it is possible to prevent the subsequent portion of the heat-meltable synthetic resin which is hardened by the contact from directly contacting the skin, and the burden on the skin is lightened, thereby reducing skin damage and the like. Moreover, according to the present invention, by selecting the thickness of the first insertion yarn, it is possible to obtain a wearing pressure (a feeling of clothing or a feeling of elasticity) according to the intended use. Moreover, according to the present invention, the combination of the core yarn and the coated yarn or the combination of the thickness of the chain knitting yarn and the second insertion yarn can improve the adhesion ratio of each yarn or change the clothing feeling of the lace.

Form a pattern. Such a patterned lace fabric 20 is used, for example, to manufacture a lace-knitted article such as a female close-fitting garment. As shown in Fig. 1, the lace knit 20 comprises: a chain knitting yarn 21 which forms a raschel warp knitting chain knit structure 19 having a plurality of annular portions 24, 25; a first insertion yarn 23 having The elastic expansion and contraction is used for knitting in the weft direction C to the chain knit structure 19 to impart flexibility to the chain knit structure 19 in the weft direction C; and the second insertion yarn 22 is elastically stretchable, and Each of the second annular portions 25 of the chain knitting yarn 21 forming the one chain knitting structure 19 and the chain knitting yarn 21 formed in the chain knitting structure 19 adjacent to the warp direction W are attached to each The chain knit structure 19 imparts stretchability in the warp direction W. The chain knitting yarn 21 is sometimes also referred to as a warp yarn or a base knitting yarn. Further, the first insertion yarn 23 is also referred to as a stretch yarn, and the second insertion yarn 22 is also referred to as a weft yarn. Further, in the lace knitted fabric 20, the chain knitting yarn 21 and the plurality of first contact portions 50 of the first insertion yarn 23 are followed by thermal fusion properties. The chain knitting yarn 21 and the first insertion yarn 23 are followed by substantially all of the first contact portions 50. Further, in the lace knitted fabric 20, the plurality of second contact portions 55 of the chain knitting yarn 21 and the second insertion yarn 22 are followed by thermal fusion properties. The chain knitting yarn 21 is followed by substantially all of the second contact portions 55 of the second insertion yarn 22. As shown in FIG. 2, the chain knitting yarn 21 is formed by chain knitting to form the first annular portion 24 and the second annular portion 25. The first annular portion 24 and the second annular portion 25 are alternately connected and arranged in the weft direction C to form a plurality of segments. Here, the first annular portion 24 may be referred to as a knitting yarn loop, and the second annular portion 25 may be referred to as a sinker loop. The first annular portion 24 and the second annular portion 25 are alternately connected and extend in the weft direction C to form a warp. A plurality of warp circles are arranged in the warp direction W to form a chain knitted structure, in other words, a twisted tissue, by joining them to each other. Further, the chain knitting yarn 21 is appropriately laterally looped and joined by chain knitting adjacent to the warp direction W to form a chain knit structure having a function of preventing the yarn from being scattered. The portion of the chain knitting yarn 21 which is laterally looped is referred to as an anti-drop portion 42. Each of the first annular portions 24 is formed substantially in a U shape, and is arranged substantially in a predetermined weft direction C and a warp direction W orthogonal to the weft direction C. Further, each of the first annular portions 24 is opened in the weft direction front portion C1 which is one side of the weft direction C. The first annular portion 24 is formed in a row in the warp direction W to form a weft ring, and the first annular portion 24 is lined up in the weft direction C to form a warp. The second annular portion 25 connects the first annular portions 24 arranged in the weft direction C. For example, it looks at one second annular portion 25. One end portion of the second annular portion 25 to be seen is connected to the end portion of the first annular portion 24 which is the same as the second annular portion 25. The second annular portion 25 is inserted from the one side toward the other side in the weft direction of the first annular portion 24 of the second annular portion 25 in the weft direction from the one end portion toward the other end portion. The rear end portion C2 extends in the ring direction, and the first annular portion 24 that is in the same section as the second annular portion 25 is inserted from the other side toward the one side and extends toward the rear portion C2 in the weft direction, and the second annular portion The end portions of the first annular portion 24 of the rear portion C2 of the weft direction of 25 are connected. In this way, the annular portions 24, 25 are connected in a chain shape to form a warp extending in the weft direction C. Each of the insertion yarns, such as the second insertion yarn 22 and the first insertion yarn 23, is knitted and woven into the warp by being interposed between the first annular portion 24 and the second annular portion 25. In the present embodiment, the weft direction C is the longitudinal direction of the knitted fabric, which means the direction in which the lace is knitted. Further, the lateral direction of the W-woven fabric in the warp direction means a direction intersecting with respect to the lace weaving direction. The first annular portion 24 is arranged in a plurality of rows in the weft direction C and the warp direction W. Further, a plurality of first annular portions 24 arranged in the weft direction C and the warp direction W are arranged substantially in line with a predetermined virtual plane. In this case, each of the knit woven yarns knitted into the chain knit structure, such as the second insertion yarns 22 and the first insertion yarns 23, are disposed on one side with respect to the virtual plane. The direction in which the respective insertion yarns 22 and 23 are arranged with respect to the virtual plane extending along the first annular portion 24 is referred to as a positive direction Z1, and the direction in which the above-described virtual planes are disposed with respect to the respective insertion yarns 22 and 23 is referred to as a reverse 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 referred to as a forward direction Z1, and a direction away from the paper surface in the direction perpendicular to the paper surface toward the back side is referred to as a reverse direction Z2. In the surface of the lace braid 20 in the positive direction Z1, the first annular portion 24 is hidden by the knitting of the second insertion yarn 22 and the first insertion yarn 23. Therefore, the pattern of the lace fabric 20 and the lace pattern are more clear than the surface of the lace braid 20 in the positive direction Z1 and the surface of the reverse direction Z2. For example, the second annular portion 25 is inserted into the first annular portion 24 of the front end portion C1 of the second annular portion 25 in the weft direction in the positive direction Z1, and is inserted into the second annular portion 25 in the reverse direction Z2. The first annular portion 24 of the same section of the weft direction is connected to the first annular portion 24 of the rear section C2 in the weft direction. The second insertion yarn 22 is used to form a lace pattern yarn in a chain knitting group. The second insertion yarns 22 are knitted by knitting into the warp rings adjacent to each other in the warp direction W, and are joined by two warps that are adjacent in the warp direction W. As shown in FIG. 1, the second insertion yarn 22 includes a transverse loop portion extending from one of the warp direction W and a loop span, and a second insert yarn knitted and woven into the warp. section. A through hole that is inserted in the thickness direction of the braid is formed in a space surrounded by the warp ring in which the two lateral loop portions arranged in the weft direction C and the transverse loop portion are joined. The shape and arrangement of the through holes can be adjusted by selectively arranging the lateral loop portions of the second insertion yarns 22. Thereby, a lace pattern which is expressed in accordance with the arrangement and shape of the through holes can be formed in the lace knitted fabric 20. Here, the through hole surrounded by the lateral loop portion and the warp may be filled with the pattern yarn described below to form a pattern. The second insertion yarn 22 extends in a region closer to the positive direction Z1 than the first annular portion 24. The second insertion yarn 22 is inserted between the first annular portion 24 and the second annular portion 25 which are set in advance, and extends in the warp direction W. Further, in the present embodiment, a plurality of second insertion yarns 22 are knitted and knitted in the chain knit structure, and each of the second insertion yarns 22 is knitted in the warp direction W and knitted. The position at which each of the second insertion yarns 22 is knitted and woven is appropriately selected in accordance with the lace pattern formed on the lace knitted fabric 20. The first insertion yarn 23 is realized by a yarn having a melting temperature equivalent to that of the chain knitting yarn 21 and the second insertion yarn 22. In the present embodiment, the yarn partially melted in a heated state in the heating step performed after the lace knitted fabric is knitted is used. In addition to imparting ductility to the lace-knitted fabric 20, the first insertion yarn 23 is also used to prevent the skein of the knit knitting yarn 21 and the second insertion yarn 22 which are formed. In the present embodiment, the first insertion yarn 23 is realized by a non-coated yarn, that is, a bare yarn that is not covered with a coated yarn, a so-called bare yarn, and has a melting temperature of about 200 ° C or higher and 250. It is achieved by a polyurethane elastic yarn below °C. The first insertion yarn 23 is knitted into the chain knit structure in a state of being stretched with respect to the natural state. The polyurethane yarn used in the chain knitting yarn 21 and the second insertion yarn 22 has a lower melting point than the polyurethane yarn used in the first insertion yarn 23, so that it is melted and the like. 1 The inserted yarn 23 is fused, whereby the loose yarn can be prevented. The first insertion yarn 23 extends along the warp and is knitted into all the annular portions constituting the warp. Therefore, in the chain knit structure, the first insertion yarn 23 is knitted into the base portion where the amount of the yarn per unit area is sparse, and the amount of the yarn per unit area is larger than the pattern portion where the base portion is dense. Further, in the present embodiment, the lace knitted fabric 20 includes a plurality of first insertion yarns 23, and each of the first insertion yarns 23 is knitted and woven into each warp. In this manner, the first insertion yarn 23 is knitted and woven throughout the entire area of the chain knit structure. The first insertion yarn 23 extends in a region in the positive direction Z1 from the first annular portion 24 and extends in a region in the opposite direction Z2 from the second annular portion 25. The first insertion yarn 23 travels in a zigzag shape as it travels along the corresponding warp direction in the weft direction C. For example, when the first insertion yarn 23 passes between the first annular portion 24 and the second annular portion 25 which are viewed from the side in the warp direction W1 toward the other side W2 in the warp direction, the first insertion yarn 23 is different from the warp direction. The one side W2 passes between the first annular portion 24 and the second annular portion 25 of the rear portion C2 in the weft direction of the first annular portion 24 that is viewed in the direction of the circumferential direction W1. Each of the first insertion yarns 23 can be realized by a structure different from the above-described structure when it is knitted in the weft. Immediately after the knitting, the first insertion yarn 23 extends in a region in the positive direction Z1 from the first annular portion 24, and extends in a region opposite to the opposite direction Z2 of the lace knitted fabric 20 from the second insertion yarn 22. Therefore, when the first insertion yarn 23 and the second insertion yarn 22 are inserted into the same region between the first annular portion 24 and the second annular portion 25, the first insertion yarn 23 is inserted into the first annular portion 24 and The second insertion yarn 22 is interposed. Further, the second insertion yarn 22 is inserted between the first insertion yarn 23 and the second annular portion 25. In this case, by stretching the chain knitting yarn 21 in the weft direction C, the radius of curvature of the first annular portion 24 and the second annular portion 25 is reduced, and the first insertion yarn 23 is placed in the second insertion. The yarn 22 and the first annular portion 24 are in contact with the second insertion yarn 22 and the first annular portion 24. In the present embodiment, the first insertion yarn 23 and the second insertion yarn 22 are inserted into the region between the first annular portion 24 and the second annular portion 25, and the first insertion yarn 23 and the second insertion yarn are inserted. 22 intersects each other and passes through the first annular portion 24 and the second annular portion 25. Specifically, the first insertion yarn 23 passes through the first annular portion 24 and the latitudinal direction in which the first annular portion 24 that is in contact with the second annular portion 25 in the latitudinal direction of the front portion C1 is connected. The second annular portion 25 of the segment. 3 is a front view showing a portion of the chain knitting yarn 21 before weaving, and FIG. 4 is a front view showing a portion of the chain knitting yarn 21 knitted into the lace knitted fabric 20. The chain knitting yarn 21 has a shape as shown in Figs. 1 and 2 in a state of being knitted into the lace knitted fabric 20. However, in Fig. 4, it is shown in a state of being linearly extended for easy understanding. The chain knitting yarn 21 is a yarn obtained by spirally winding the covered yarn 31 to the stretchable core yarn 30. The core yarn 30 is a single fiber yarn (filament yarn) containing a thermoplastic synthetic resin, and contains, for example, a polyester-based polyurethane. The covered yarn 31 is a long-fiber yarn (filament yarn) composed of a plurality of long fibers including a synthetic resin, and contains, for example, polyamine (trade name: nylon). As shown in FIG. 3, the chain knitting yarn 21 is covered with the covering yarn 31 so that the covering yarns 31 are in contact with each other and the core yarn 30 is not exposed, as shown in FIG. The chain knitting yarn 21 is knitted in a state of being stretched as shown in Fig. 4 by the stretchability of the core yarn 30. The chain knitting yarn 21 is in a state of being stretched, that is, a spiral gap is formed between the covered yarns 31, and the core yarn 30 is exposed from the gap. The second insertion yarn 22 includes a core yarn of a single fiber yarn made of a thermofusible synthetic resin, a long fiber yarn (filament yarn) composed of a plurality of long fibers including a synthetic resin, and for example, a polyamide (trademark) Name: Nylon), enamel, polyester, etc. The first insertion yarn 23 is also called a spandex elastic fiber yarn, and is a long-fiber yarn (filament yarn) containing a stretchable material, and contains, for example, a polyester-based polyurethane. The core yarn 30 and the first insertion yarn 23 of the chain knitting yarn 21 each contain a polyester-based polyurethane, but contain a polyester-based polyurethane having a different type and a melting of the core yarn 30. The temperature is lower than the melting temperature (about 200 to 250 ° C) of the first insertion yarn 23 . The core yarn 30 has a melting temperature of about 140 to 190 ° C, and has a lower melting temperature than the covering yarn 31, the second insertion yarn 22, and the first insertion yarn 23, and has thermoplasticity. Thus, the chain knitting yarn 21 is a yarn comprising a core yarn 30 containing a material having a lower melting temperature. Further, the core yarn of the second insertion yarn 22 may have a melting temperature equal to that of the core yarn 30 of the chain knitting yarn 21. Fig. 5 is a flow chart showing an example of a manufacturing procedure of the lace knitted fabric 20 of the present embodiment. First, in step a0, the selection of each yarn for knitting the lace knitted fabric 20, the determination of the pattern to be formed on the lace knitted fabric 20, the design of the knitted fabric for forming the desired knitted structure, and the like are completed. When the preparation of the knit knitting is completed, the process proceeds to step a1 to start the manufacture of the lace knitted fabric 20. In the step a1 as the braid weaving step, the body knitted fabric is knitted as a front body of the lace fabric 20 by using a knitting machine as a raschel warp knitting machine. The knitting machine knits the yarns 21, 22, and 23 of the first insertion yarn 23 and the second insertion yarn 22 into the chain knitting yarn 21 in accordance with the knitting sequence designed in the step a0, and weaves the knitting yarn shown in Fig. 1. The fabric 20 is identical to the woven tissue precursor knit. In the precursor knitted fabric, the chain knitting yarn 21 and the first insertion yarn 23 have stretchability. The knitting machine performs the weaving operation in a state in which the stretchable yarn is stretched. The precursor knitted fabric is shrunk after knitting by the restoring force of the woven yarn which is knitted in an extended state, and if the stretchability is maintained to the lace knitted fabric 20, the lace knitted fabric 20 becomes a stretchable elastic lace knitted fabric. When the knitting of the precursor knitted fabric is completed in this manner, the process proceeds to step a2. In the step a2 as the dyeing step, the precursor knitted fabric knitted in the step a1 is dyed, and when the dyeing is completed, the process proceeds to the step a3. In the step a3, the body knitted fabric before dyeing is heated to a temperature higher than the melting temperature of the core yarn 30 of the chain knitting yarn 21 and less than the melting temperature of the yarns 22, 23, 31 other than the core yarn 30. When the precursor knitted fabric is heated in the step a3, the precursor knitted fabric is stretched, and the chain knitting yarn 21 is heated in a state of being elongated as shown in Fig. 4. Thereby, the core yarn 30 of the chain knitting yarn 21 is partially heated and melted. Further, the core yarn of the second insertion yarn 22 may have a melting temperature equal to that of the core yarn 30 of the chain knitting yarn 21. Therefore, the first contact portion 50 in which the first insertion yarn 23 of the chain knitting yarn 21 and the first insertion portion 50 of the first insertion yarn 23 is in contact with the exposed portion of the core yarn 30, the chain knitting yarn 21 and the first Insert the yarn 23 followed. Further, the chain knitting yarns 21 are next to each other in the second contact portions 55 in which the portions of the second contact portions 55 of the chain knitting yarns 21 that are exposed by the core yarns 30 are in contact with each other. The contact portions 50 and 55 are in a form in which the molten core yarn passes through the characteristic shape of the covered yarn and the most central side of the curved portion, and the portion having the highest probability of follow-up, but there are cases in which the contact portions 50 and 55 are present. The molten core yarn is exposed at a position other than that, and if it is shaped in contact with other fibers, the succeeding portion is formed. Although the core yarn 30 of the chain knitting yarn 21 and the first insertion yarn 23 are different in type, they all contain a polyester-based polyurethane, and therefore, the core yarn 30 is melted, and it is easy to heat-melt and merge. Further, the coated yarn 31 of the chain knitting yarn 21 contains polyamine, and it is difficult to follow the core yarn 30, and the setting temperature and the setting time are adjusted by the majority of the first contact portion 50 as described above. In the case of the molten core yarn and the stretched polyurethane yarn, the core yarn 30 of the chain knitting yarn 21 and the first insert yarn 23 can be wound by about 60 to 90% in the first contact portion 50. The rate goes on. Further, in the second contact portion 55 of the chain knitting yarn 21 and the second insertion yarn 22, the portions where the core yarn 30 is exposed are in contact with each other, and are followed by a bonding ratio of about 50 to 80%. The precursor knitted fabric is heated in such a manner that the chain knitting yarn 21 is partially connected to one of the first contact portions 50 of the first insertion yarn 23, and one of the second contact portions 55 of the chain knitting yarns 21 is partially joined to form a portion. Lace the braid 20 and proceed to step a4. In the step a4, the formed lace knitted fabric 20 is cut (when the width is maintained as it is), and the manufacturing operation of the lace knitted fabric 20 is completed in the step a5. Since the core knitted fabric 30 of the chain knitting yarn 21 is melted by heating the precursor knitted fabric in the step a2, the stretchability is impaired, but the first inserted yarn 23 is heated only to a temperature that does not reach the melting temperature, so that it can be maintained. Scalability. Therefore, the lace braid 20 has stretchability. According to the lace knitted fabric 20 of the present embodiment as described above, the stretchable first insertion yarn 23 is knitted into the chain knit structure 19 to impart stretchability to the chain knit structure, thereby realizing stretchable lace. Braid. Further, the chain knitting yarn 21 and a portion of the first contact portion 50 of the first insertion yarn 23 are partially followed, and the chain knitting yarns 21 or a portion of the second knitting portion 21 of the chain knitting yarn 21 and the second insertion yarn 22 are adjacent to each other. Follow each other. Thereby, the positional deviation of the chain knitting yarn 21 and the first insertion yarn 23, and the positional deviation of the chain knitting yarns 21 or the chain knitting yarn 21 and the second insertion yarn 22 can be prevented, thereby preventing the lattice. Deformation. For example, even if an external force is caused by a manufacturing process such as sewing or cutting of the lace knitted fabric, and an external force is caused by a wearing state such as wearing or washing, the lattice shape can be prevented from being deformed and the shape of the lattice can be maintained, thereby obtaining a good appearance. The lace braid is also capable of maintaining the excellent appearance for a long period of time. The chain knitting yarn 21 and the first insertion yarn 23 are knitted by the knit knitting yarn 21 knitted by the entire knitted fabric 20, the first insertion yarn 23, and the second insertion yarn 22, and the chain is followed by the chain. Since the knitting yarn 21 and the second insertion yarn 22 are attached to each other, the composition of the different yarns is not partially used, so that uniformity is obtained visually and tactilely, and the appearance and texture are not impaired. Further, the chain knitting yarn 21 which is covered with the core yarn 30 by the covering yarn 31 is stretched, and the portion where the core yarn 30 is exposed is followed. Therefore, the surface of the covering yarn 31 is not covered by the melt of the core yarn 30. In the case where the lace knitted fabric 20 and the lace-knitted product produced using the same, the molten product of the core yarn 30 does not come into contact with the skin, and the covered yarn 31 comes into contact with the skin. Since the covered yarn 31 is a collection of a plurality of individual fibers, a soft and soft feeling can be obtained, and a good texture can be maintained. The texture here refers to the hand feeling, and the good texture refers to the softness and softness of the hand. Further, the chain knitting yarn 21 and the first contact portion 50 of the first insertion yarn 23, and the chain knitting yarn 21 and the second contact portion 5 of the second insertion yarn 22 are substantially all connected, so that the appearance is good and the texture is obtained. The excellent stretchable lace woven fabric is configured to prevent the position of the chain knitting yarn 21 and the first insertion yarn 23 which are easy to affect the deformation of the lattice as much as possible in either of the weft direction C and the warp direction W. The offset and the position of the chain knitting yarn 21 and the second insertion yarn 22 are shifted, and the stretchability and flexibility are not impaired, and the yarn is less likely to be generated at a high tensile strength. The heating condition in the step a3 of the heat setting step is set to a heating condition in which the core yarn 30 of the chain knitting yarn 21 is melted and the characteristic including the brittleness of the yarn other than the core yarn 30 is prevented. Further, the heating condition in the heating step is preferably set to a heating condition in which the core yarn 30 is heated to a temperature attainable as a form of the yarn. Thereby, the melt of the core yarn 30 can be prevented from appearing on the surface of the knitted fabric and is not easily contacted with the skin. Regarding the heating conditions, for example, the heating temperature and the heating time are set. The minimum melting temperature at which the core yarn 30 is melted is B1, and the time from heating at the lowest melting temperature to softening is taken as D1. Further, the minimum characteristic change temperature at which the characteristics of the yarn other than the core yarn 30 are changed is B2, and the time until the characteristic changes due to heating at the lowest characteristic change temperature is D2. In this case, in the present embodiment, when the heating temperature in the heating step is B3 and the heating time is D3, B1 < B3 < B2 and D1 < D3 < D2 are set. Further, B3 is set as close as possible to the value of B1, and D3 is set as close as possible to the value of D1, whereby the form of the core yarn 30 as the yarn can be easily maintained. In the present embodiment, as the core yarn 30 of the chain knitting yarn 21, a polyester-based thermoplastic polyurethane of 10 denier or more and 280 denier or less, preferably 10 denier or more and 70 denier or less is used. Ester elastic yarn. Further, the heat treatment is performed at a heating temperature of 170 ° C or more and 195 ° C or less, and a heating time of 30 sec or more and 90 sec or less. Thereby, the core yarn 30 can be melted, and the characteristic change of the remaining yarn can be prevented. Further, the fineness of the first insertion yarn 22 is selected to be, for example, 40 denier or more and 420 denier or less. The core yarn of the second insertion yarn 21 may be the same as the core yarn 30 of the chain knitting yarn 21. For example, when the heating time is fixed, if the heating temperature is set to less than 170 ° C, the adhesion force of the core yarn 30 after melting becomes small. Further, when the heating temperature exceeds 195 ° C, it is difficult to maintain the form of the core yarn 30 as a yarn, and the characteristics of the yarn other than the core yarn 30 change. On the other hand, in the present embodiment, the above problem can be prevented by setting the heating temperature to 170° C. or higher and 195° C. or lower as described above. The finer the core yarn 30 is, the closer the contact portion is to the point contact, the smaller the texture, the better the texture, and the thicker the core yarn 30, the larger the adhesion portion and the texture is damaged. In order to thicken the core yarn 30 and maintain a good texture, it is considered that the covered yarn 31 is thickened, but the chain knitting yarn 21 becomes thick, thereby impairing the transparency of the lace knitted fabric. Further, the finer the core yarn 30 is, the smaller the strength is, and the thicker the core yarn 30 is, the stronger the strength is. Further, by the combination of the core yarn 30 and the covered yarn, it is possible to form a clothing feeling corresponding to the use. Further, by setting the respective yarns themselves to be thick or combined, it is also possible to improve the burst strength. Therefore, when the core yarn 30 is a fine yarn of less than 10 denier, there is a problem that the strength becomes too small, and when the core yarn 30 is a thick yarn of more than 140 Danny, it is damaged. The problem of texture. By setting the core yarn 30 to 10 denier or more and 140 denier or less, it is possible to obtain a lack of strength and a good texture. From the same viewpoint, it is preferable to set the core yarn 30 to 10 denier or more and 50 denier or less. Further, since the lace knitted fabric 20 is followed by the first and second contact portions 50 and 55 as described above, there is an effect of preventing the development of the yarn of the yarn. Therefore, for example, the lace knitted fabric 20 can be cut in an arbitrary shape in a manner called a pattern cut, a free cut, or the like. Therefore, it has high stretchability and form stability in either of the warp direction W and the weft direction C, and can be formed by molding or the like. The lace woven fabric 20 manufactured in this manner is formed in the cutting step a4 in order to form a desired three-dimensional shape for a woman's underwear or the like, for example, at 180 ° C, and cut into individual processed products, and ends in step a5. Manufacturing operations. The lace woven fabric 20 of the present invention can prevent the yarn from being sewed by the first and second contact portions 50 and 55 as described above. Therefore, the detachment preventing portion 42 or the detachment preventing portion 42 can be formed. Less composition. If the configuration is such that the anti-dropper portion 42 or the anti-dropper portion 42 is small, the traverse of the chain knitting yarn 21 can be eliminated or reduced, and the appearance can be improved and the quality can be improved. The above embodiment is merely an exemplification of the present invention, and the configuration can be changed. For example, the material of each of the yarns 21 to 23 can be appropriately changed.
