Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples. First, with reference to FIGS. 1 to 4, the configuration of the patterned knitted lace 1 will be described. FIG. 1 is a diagram exemplifying the patterned knitted lace 1 in the present embodiment. As illustrated in FIG. 1, the patterned knitted lace 1 (hereinafter, lace 1) is, for example, a knitted lace used for at least a part of a knitted lace product. The knitted lace product is a knitted lace product including the lace 1 at least in part, and examples thereof include clothing such as innerwear, outerwear, or sportswear, medical instruments such as bandages, supporters such as corsets, corrective belts, or corrective bands, skin care products such as under-eye masks, sheet masks, or face masks, or interior products such as curtains. The knitted lace product in this example is clothing. The clothing is used, for example, for all or part of women's innerwear (underwear). Women's innerwear includes foundation (basic underwear), lingerie (decorative underwear), and underwear (next to the skin). This lace 1 is, for example, a Raschel lace of a warp knitted fabric knitted by a warp knitting machine such as a Raschel machine, and a plurality of through holes are formed, and a lace pattern is formed by the combination of the shapes and arrangements of the respective through holes. The lace 1 has a ground structure 2 and a pattern part 6 knitted into the ground structure 2.

[0016] The ground fabric 2 is a knitted fabric formed by connecting two adjacent basic fabrics (basic fabric 12 described later) to each other. The ground fabric 2 is, for example, a chain stitch fabric, a tulle fabric, an atlas fabric, or a power net fabric, etc. Note that the ground fabric 2 in this example is a chain stitch fabric and has a run prevention (fraying prevention) function of going back and forth between adjacent basic fabrics 12 (wales). Also, the ground fabric 2 includes a watermark portion 4 and a ground pattern 5. The watermark portion 4 is an area where the amount of yarn arranged per unit area is sparse, and through holes which are various plural meshes are arranged. The ground pattern 5 is an area where the amount of yarn arranged per unit area is dense and is formed into a predetermined pattern. The pattern portion 6 is an area where pattern yarns are knitted into the ground fabric 2 to decorate the ground fabric 2. The pattern portion 6 exhibits the outline, shading, or unevenness of a floral pattern (hereinafter, may also be referred to as a pattern motif) depending on the thickness and density of the knitted pattern yarns.

[0017] FIG. 2 is an example diagram for explaining the knitting structure of the lace 1 with pattern. For the convenience of explanation, intervals are provided between the respective yarns, but actually the respective yarns are in close contact with each other. As illustrated in FIG. 2, the lace 1 has a chain stitch yarn 10, a basic fabric 12 formed by the chain stitch yarn 10, a first stitch 14, a second stitch 15, an inserted yarn 20, an inserted yarn 40 (not shown), a jacquard yarn 50 (not shown), and a pattern yarn 60 (not shown).

[0018] The chain stitch yarn 10 is a knitting yarn that forms a basic fabric 12 (described later) in which a plurality of chain stitches are continuous. The chain stitches formed by the chain stitch yarn 10 include a needle loop 10A and a sinker loop 10B. The chain stitch yarn 10 forms the basic fabric 12 that serves as the basis of the ground fabric 2 by continuously forming chain stitches. In addition, the chain knitting yarn 10 is a yarn formed of synthetic fibers among chemical fibers, and is a single material yarn or a composite yarn. For example, when the chain knitting yarn 10 is a single material yarn (for example, a filament yarn), it is formed of polyamide nylon (nylon), acrylic, polyester, or the like. Further, when the chain knitting yarn 10 is a composite yarn, for example, it is a composite yarn in which a heat-fusible elastic yarn, which is an elastic yarn that adheres to other yarns by melting the material by heat, is used as a core yarn and a nylon yarn is coated. Further, the chain knitting yarn 10 may be a yarn containing functional fibers such as contact heat sensation, contact cold sensation, or antibacterial and deodorant properties. As the heat-sensitive functional fiber yarn, for example, acrylic fiber yarn, as the cold-sensitive functional fiber yarn, for example, cupra fiber yarn, and other materials and composite material combinations can be appropriately selected according to the purpose and effect to be added, such as antibacterial and deodorant. Further, as the composite method of the composite yarn, for example, in addition to covering processing, air entanglement processing, or twisting processing, known composite processing methods can be appropriately selected. Note that the chain knitting yarn 10 in this example is a multifilament yarn formed of nylon.

[0019] The basic weave 12 is formed by the chain knitting yarn 10 and is a knitting structure in which a plurality of chain stitches are continuous. The basic weave 12 includes basic weaves 12A to 12D as illustrated in FIG. 2. For convenience of explanation, the basic weaves 12A to 12D are referred to as the basic weave 12 when there is no particular need to distinguish them. The basic weave 12 is arranged in parallel in a direction (hereinafter referred to as the course direction) in which a plurality of chain stitches are continuous and a direction (hereinafter referred to as the wale direction) orthogonal to the course direction. Further, in two adjacent basic weaves 12, the respective chain stitches are arranged at adjacent positions. Further, the basic structure 12 has a run stop portion 100 that connects two adjacent basic structures 12. The run stop portion 100 is formed by the chain knitting yarns 10 that form the basic structure 12, and it crosses from the chain stitches of one basic structure 12 to the chain stitches of the other basic structure 12 among two adjacent basic structures 12, connecting the two adjacent basic structures 12. The run stop portions 100 are arranged regularly. The period for arranging the run stop portions 100 is, in the course direction of the basic structure 12, for example, a period of 3 courses or more, preferably a period of 3 courses or more and 20 courses or less, more preferably a period of 3 courses or more and 9 courses or less, and even more preferably a period of 3 courses or more and 7 courses or less. In this example, the run stop portion 100 connects two adjacent basic structures 12 at a period of 3 courses. Note that the run stop portion 100 is an example of the connecting portion according to the present invention.

[0020] The first stitch 14 is a stitch that includes the needle loop 10A formed by the chain knitting yarn 10 and the needle loop 20A formed by the insertion yarn 20, which will be described later, among the plurality of chain stitches of the basic structure 12. In the first stitch 14 of this example, the needle loop 20A of the insertion yarn 20 has melted and adhered to the needle loop 10A of the chain knitting yarn 10. Further, the first stitch 14 is a chain stitch at the position where the run stop portion 100 is provided.

[0021] The second stitch 15 is a stitch of the needle loop 10A formed by the chain knitting yarn 10 among the plurality of chain stitches of the basic structure 12. That is, the second stitch 15 is a chain stitch that only includes the needle loop 10A and does not include the needle loop 20A. In the second stitch 15 of this example, the insertion yarn 20 is positioned inside or outside the sinker loop formed by the chain knitting yarn 10. In the second stitch 15 of this example, the insertion yarn 20 is inserted through the sinker loop formed by the chain knitting yarn 10 and adhered at the contact point between the inserted insertion yarn 20 and the sinker loop. Further, the second stitch 15 is a chain stitch at the position where the run stop portion 100 is not provided.

[0022] The inserted yarn 20 is an example of the inserted yarn according to the present invention, and is a yarn inserted into a plurality of stitches of the basic fabric 12 in the direction in which a plurality of chain stitches are continuous. The inserted yarn 20 is inserted into each basic fabric 12 (in FIG. 2, 12A to 12D) in the course direction. Further, the inserted yarn 20 includes a needle loop 20A. The needle loop 20A is a needle loop formed by the inserted yarn 20. The needle loop 20A is provided in some of the plurality of stitches included in the basic fabric 12. Specifically, the needle loop 20A is regularly provided in some of the plurality of stitches included in the basic fabric 12. For example, the period of arranging the needle loops 20A may be provided every one stitch, or may be provided every plurality of stitches, or every plurality of stitch positions. Specifically, the period of arranging the needle loops 20A may be, for example, every 2 or more and 10 or less stitches, or provided every 2 or more and 10 or less stitch positions. In addition, the period of arranging the needle loops 20A in this example is provided every three stitches including one first stitch 14 and two second stitches 15. Specifically, one first stitch 14 is provided every two second stitches 15. Further, the needle loop 20A is provided in a chain stitch including a transverse run-stopping portion 100. Here, the formed needle loop 20A may be an open loop or a closed loop, and is a closed loop in this example. Further, the needle loop 20A is provided in contact with the needle loop 10A. Specifically, the needle loop 20A may be in contact with the needle loop 10A in a state where at least a part thereof is in close contact, or may be in contact in a state where at least a part thereof intersects or overlaps.

[0023] Further, the inserted yarn 20 is, for example, mainly an adhesive yarn, mainly a non-adhesive yarn, or a yarn having adhesiveness and elasticity. When the inserted yarn 20 is, for example, mainly an adhesive yarn, it is a heat-fusing yarn or a heat-sealing yarn. An adhesive yarn is a yarn formed of a material that adheres to other yarns. For example, it includes a heat-fusing yarn that melts and deforms by heat and adheres to other yarns, and a heat-sealing yarn that deforms and adheres by entering the irregularities of other yarns by heat. Further, when the inserted yarn 20 is, for example, mainly a non-adhesive yarn, it is, for example, a chemical fiber yarn, a natural fiber yarn, or a composite yarn containing at least one of these. The chemical fiber yarn is, for example, a yarn formed of polyurethane elastic yarn (so-called spandex), nylon, polyester, etc. (In the case of polyurethane elastic yarn, a polyurethane elastic yarn without heat fusibility may sometimes be referred to as a polyurethane stretch yarn). Also, the natural fiber yarn is a yarn formed of cotton, silk, wool, etc. Further, the composite yarn containing at least one of these is a yarn containing at least one of a chemical fiber yarn such as polyurethane elastic yarn, nylon, or polyester and a natural fiber yarn such as cotton, silk, or wool. Also, the inserted yarn 20 is preferably a yarn with relatively high frictional force, for example, a polyurethane elastic yarn or a composite yarn containing a polyurethane elastic yarn. The polyurethane elastic yarn is a yarn having both anti-slip property and stretchability, preventing the yarn from slipping out and contributing to the stretchability of the fabric. Also, when the inserted yarn 20 is a yarn having adhesiveness and stretchability, it is a yarn formed by forming a material having heat fusibility and stretchability into a yarn shape, for example, a heat-fusible polyurethane elastic yarn (Note that a polyurethane elastic yarn having heat fusibility may sometimes be referred to as a polyurethane adhesive yarn). Also, the inserted yarn 20 may be a composite yarn containing an elastic yarn that stretches in the length direction of the yarn. For example, it may be a composite yarn in which a covering yarn covers an elastic core yarn. Note that the inserted yarn 20 in this example is a heat-fusible polyurethane elastic yarn that is a yarn having heat fusibility and stretchability, and stretches more than the chain stitch yarn 10. The inserted yarn 20 in the heat-fused state includes at least a part where this yarn is continuous. The inserted yarn 20 may be only the part where this yarn is continuous, or may include the part where this yarn is continuous and the part where this yarn breaks. The inserted yarn 20 in this example generally includes a part where the yarn is continuous.

[0024] The functional insert yarn 40 is an insert yarn with excellent functionality inserted into the chain stitches of the basic fabric 12 formed by the chain knitting yarn 10. The functional insert yarn 40 of this example is inserted into a plurality of chain stitches in each basic fabric 12 (in FIG. 2, 12A to 12D) in the course direction. The functional insert yarn 40 includes at least one of an elastic yarn 41, an adhesive yarn 42, and a functional yarn 43. The functional insert yarn 40 may insert all of the elastic yarn 41, the adhesive yarn 42, and the functional yarn 43 into the chain stitches of the basic fabric 12, or may select and insert two of the elastic yarn 41, the adhesive yarn 42, and the functional yarn 43, or may select and insert one of the elastic yarn 41, the adhesive yarn 42, and the functional yarn 43. The functional insert yarn 40 of this example selects two of the elastic yarn 41 and the adhesive yarn 42 and inserts them into the chain stitches of the basic fabric 12.

[0025] The elastic yarn 41 is an example of the second insert yarn according to the present invention and is an elastic yarn that stretches in the length direction of the yarn. The elastic yarn 41 is, for example, a polyurethane elastic yarn (so-called spandex), and is a polyurethane elastic yarn having no heat-sealing property (note that a polyurethane elastic yarn having no heat-sealing property may also be referred to as a polyurethane stretch yarn). The elastic yarn 41 of this example stretches the basic fabric 12 in the course direction. As a result, the elastic yarn 40 imparts stretchability to the ground fabric 2, and the knitting lace 1 can be made into a stretch lace.

[0026] Next, the adhesive thread 42 is an example of the second inserted thread according to the present invention, and is a thread formed by shaping an adhesive material, specifically a heat-sealable material, into a thread. The adhesive thread 42 exhibits an adhesive function with other threads by melting the material with heat. Further, the adhesive thread 42 may be an elastic adhesive thread that stretches in the longitudinal direction of the thread in addition to heat-sealability. The adhesive thread 42 in this example is a heat-sealable polyurethane elastic thread. Also, the adhesive thread 42 may be a composite thread including an elastic thread that stretches in the longitudinal direction of the thread. For example, it may be a composite thread in which a covering thread covers an elastic core thread. The adhesive thread 42 in the heat-sealed state includes at least a portion where this thread is continuous. The adhesive thread 42 may be only the portion where this thread is continuous, or may include the portion where this thread is continuous and the portion where this thread breaks. The adhesive thread 42 in this example generally includes a portion where the thread is continuous.

[0027] The functional thread 43 is an example of the second inserted thread according to the present invention, and is a thread mainly composed of functional fibers such as contact heat sensation, contact cold sensation, or antibacterial and deodorant properties. The functional thread 43 is a single material thread or a composite thread, and may be, for example, an acrylic fiber thread as a heat-sensing functional fiber thread, a cupra fiber thread as a cold-sensing functional fiber thread, or a composite thread in which materials according to additional purposes and effects such as other antibacterial and deodorant properties are appropriately combined.

[0028] The jacquard thread 50 is an example of the third inserted thread according to the present invention, and is an inserted thread that is inserted into the chain stitch of the basic structure 12 formed by the chain stitch thread 10 and connects two adjacent basic structures 12 to form a ground structure 2 with a lace pattern. The jacquard thread 50 is located between the inserted thread 20 and the inserted thread 40. The jacquard yarn 50 is a single-material yarn or a composite yarn. In this example, it is a single-material yarn. When the jacquard yarn 50 is a single-material yarn, it is, for example, a synthetic fiber or a regenerated fiber. Also, when the jacquard yarn 50 is a composite yarn, it is, for example, a composite yarn of natural fiber or regenerated fiber and synthetic fiber, or a composite yarn of synthetic fibers. Here, the natural fiber is, for example, cotton, hemp, silk, or wool, etc., and the regenerated fiber is, for example, rayon, cupra, or polynosic, etc. Also, the synthetic fiber is, for example, acrylic, polyester, nylon, or polyurethane, etc. Also, the jacquard yarn 50 may be an adhesive yarn that thermally fuses, for example, a polyurethane adhesive yarn, or a composite yarn with a polyurethane elastic yarn as the core yarn and a nylon yarn covering it. Thereby, fraying and tearing of the ground weave 2 can be prevented. The composite method of the jacquard yarn can appropriately select a known composite method such as covering processing, air entanglement processing, or twisting processing, etc., and it is a composite yarn manufactured by the above composite method suitable for the conditions. Also, the jacquard yarn 50 may be a yarn mainly composed of functional fibers such as contact heat sensation, contact cold sensation, or antibacterial and deodorant, etc. As the heat-sensitive functional fiber yarn, for example, acrylic fiber yarn, as the cold-sensitive functional fiber yarn, for example, cupra fiber yarn, or a composite yarn appropriately combining materials according to the additional purposes and effects such as antibacterial and deodorant, etc. may also be used.

[0029] The pattern yarn 60 is an inserted yarn that is inserted into the chain stitches of the basic weave 12 formed by the chain stitch yarn 10, connects two adjacent basic weaves 12, and forms a lace pattern or a pattern. The pattern yarn 60 is located on the front side of the knitted lace 1 and forms the pattern part 6 by forming a predetermined pattern. The pattern yarn 60 is knitted into the ground weave 2 illustrated in FIG. 1 to form the pattern part 6. The knitted pattern yarn shows the outline, shading, or unevenness of the pattern motif on the ground weave 2 according to the thickness and the density per unit area.

[0030] FIG. 3 is a diagram for explaining the details of the knitting structure of the knitted lace 1 with a pattern. FIG. 4 is a cross-sectional view for explaining the details of the knitting structure of the knitted lace 1 with a pattern. For convenience of explanation, intervals are provided between the respective yarns, but in reality, the respective yarns are in contact or close contact with each other. As illustrated in FIG. 3, the inserted yarn 20 is inserted into the basic structure 12 in the course direction of the lock stitch structure 12, and needle loops 20A are regularly provided in some stitches. Here, among the stitches of the basic structure 12, the stitch including the needle loop 20A formed by the inserted yarn 20 is referred to as the first stitch 14, and the stitch not including the needle loop 20A is referred to as the second stitch 15. Further, the elastic yarn 41 and the adhesive yarn 42 are inserted into the basic structure 12 in the course direction of the lock stitch structure 12. Further, the jacquard yarn 50 or the pattern yarn 60 connects two adjacent basic structures 12 in the wale direction of the lock stitch structure 12. The lock stitch structure 12 is formed by arranging a set of three stitches, i.e., one first stitch 14 and two second stitches 15, in the course direction. The first stitch 14 is arranged at a period of every other second stitch 15. Therefore, the needle loops 20A are arranged at a period of being provided in every other stitch. That is, the needle loops 20A are provided in some stitches where the first stitch 14 and the second stitch 15 are regularly arranged in the lock stitches of the lock stitch structure 12. Further, in the first stitch 14, the lock stitch yarn 10 and the inserted yarn 20 are formed such that the needle loop 10A of the lock stitch yarn 10 and the needle loop 20A of the inserted yarn 20 overlap each other. Therefore, even if the inserted yarn 20 is a non-adhesive yarn, fraying is reduced due to the tightening caused by the difference in tension between the lock stitch yarn 10 and the inserted yarn 20 and the accompanying frictional resistance. In addition, when the inserted yarn 20 is an adhesive yarn, other yarns are adhered to each other through the inserted yarn 20, so that fraying is further reduced. Note that the lock stitch structure 12 of this example describes the case where the first stitch 14 of one stitch is periodically arranged, but is not limited thereto, and two or more (plural) consecutive first stitches 14 may be periodically arranged. Further, the inserted yarn 20 can also be arranged in a combination of one first stitch 14 and a plurality of consecutive first stitches 14.

[0031] FIG. 4 is a cross-sectional view for explaining the detailed knitting structure of the knitted lace 1 with a pattern. As illustrated in Fig. 4, the stitches of the chain stitch fabric 12 are formed by the needle loops 10A located on the front side of the knitting course 1 and the sinker loops 10B located on the back side of the knitting course 1 in the thickness direction of the knitting course 1. Then, the inserting yarn 20, the inserting yarn 40, the jacquard yarn 50, and the pattern yarn 60 are inserted into the stitches of the chain stitch yarn 10. The inserting yarn 20 is located on the front side of the knitting course 1 with respect to the jacquard yarn 50 and the pattern yarn 60, and the functional inserting yarn 40 is located on the back side of the knitting course 1 with respect to the jacquard yarn 50 and the pattern yarn 60. And the jacquard yarn 50 and the pattern yarn 60 are located between the inserting yarn 20 and the inserting yarn 40. In this way, by regularly providing the needle loops 20A in some of the stitches of the knitting course 1, the knitting course 1 can improve the transparency and prevent fraying. Also, the knitting course 1 suppresses the exposure frequency of the needle loops 20A of the inserting yarn 20 in the first stitch 14 on the front side of the knitting course 1. Thereby, in the portion of the knitting course 1 that contacts the skin, an excessive sticky feeling of rubber can be suppressed.

[0032] Next, with reference to Fig. 5, a manufacturing method of the knitting course 1 will be described. Fig. 5 is a flowchart for explaining the manufacturing method (S10) of the patterned knitting course 1. The knitting course 1 of the present embodiment is knitted by a front jacquard raschel knitting machine (hereinafter referred to as a front jacquard machine). Hereinafter, in the manufacturing method of this example, the knitting course fabric is knitted using the above front jacquard machine, the knitted course fabric is dyed, and the dyed course fabric is heat-treated to obtain the knitting course 1. Note that, in this example, it is knitted by a front jacquard machine, but it is not limited thereto, and it can also be realized by a back jacquard machine or the like.

[0033] As illustrated in FIG. 5, in step 100 (S100), the operator guides the chain knitting yarn 10 to the knitting needles by the ground reed to form chain stitches for warp knitting, and forms a plurality of basic structures 12 by continuously arranging a plurality of the formed chain stitches in the course direction. The formed basic structures 12 are provided in parallel at equal intervals in the wale direction. Further, the chain knitting yarn 10 is made to cross over in a cycle of three courses, a locking portion 100 is inserted, and two adjacent basic structures 12 are connected.

[0034] In step 102 (S102), the operator causes the front jacquard machine to insert the inserting yarn 20 into the chain stitches of the basic structure 12 formed by the chain knitting yarn 10 in the course direction to form a needle loop 20A, which serves as the first stitch 14.

[0035] In step 104 (S104), the operator causes the front jacquard machine to form a second needle loop 20A in the chain stitches at regular positions from the first stitch 14 in which the needle loop 20A is formed. As illustrated in FIG. 3, the operator provides the first stitch 14 in which the needle loop 20B is formed in the chain stitches at the position two stitches away from the first stitch 14 in which the needle loop 20A is arranged.

[0036] In step 104 (S104), the operator causes the front jacquard machine to insert the inserting yarn 40 into the chain stitches of the basic structure 12 in the course direction. As illustrated in FIGS. 2 and 3, at least a part of the elastic yarn 41 and the adhesive yarn 42 are arranged in the same insertion path in the course direction of the same basic structure 12. The elastic yarn 41 and the adhesive yarn 42 in this example are arranged so as to have the same insertion path. Specifically, the elastic yarn 41 and the adhesive yarn 42 are arranged such that the chain stitch at the insertion source and the chain stitch at the insertion destination are the same chain stitch, and the yarn path from the chain stitch at the insertion source to the chain stitch at the insertion destination is the same, and they are arranged to run parallel to each other as a whole. Note that the elastic yarn 41 and the adhesive yarn 42 may have insertion paths that cross each other.

[0037] In step 106 (S106), the operator causes the front jacquard machine to insert the jacquard yarn 50 and the pattern yarn 60 into the chain stitches of the basic weave 12 in the course direction. Thereby, the operator forms the watermark portion 4, the ground pattern 5, and the pattern portion 6 illustrated in FIG. 1. Among the plurality of jacquard yarns 50 inserted into the basic weave 12, two adjacent jacquard yarns 50 may be arranged such that, for example, they are symmetric at least in part and at least in part overlap or intersect each other. As described above, in steps S100 to S106, knitting and the like are performed on the same course in the knitting operation of the front jacquard knitting machine, and the lace fabric before dyeing is manufactured.

[0038] In step 108 (S108), the operator dyes the knitted lace fabric. In this example, the case of after-dyeing is described, but the present invention is not limited thereto, and pre-dyeing may be performed, or this step can be omitted if it is the original yarn.

[0039] In step 110 (S110), the operator performs a heat treatment (heat setting step) of heating at a temperature at which the inserted yarn 20 and the adhesive yarn 42 of the lace fabric melt. The heat setting conditions during the heat setting step are, for example, a temperature of 160°C or higher and 200°C or lower for 90 seconds or less, preferably 180°C or higher and 190°C or lower for 40 seconds or more and 80 seconds or less. By the heat setting step, the inserted yarn 20 and the adhesive yarn 42 melt. The melted inserted yarn 20 and adhesive yarn 42 adhere to the chain knitting yarn 10, the jacquard yarn 50, and the pattern yarn 60 at the continuous part of the yarn and at the partially broken part. Thereby, in the first stitch 14, the needle loop 20A of the inserted yarn 20 adheres to the needle loop 10A of the chain knitting yarn 10. Also, in the second stitch 15, the inserted yarn 20 adheres to the chain knitting yarn 10 at the position where it passes through the sinker loop of the chain knitting yarn 10 and at the position where it contacts the sinker loop. Thereby, the operator can obtain the knitted lace 1 illustrated in FIG. 1.

[0040] As described above, according to the braid lace 1 of the present embodiment, the needle loops 20A are regularly arranged with the insertion yarn 20 inserted into the chain stitches of the basic structure 12, and the needle loops 10A of the chain knitting yarn 10 and the needle loops 20A of the insertion yarn 20 are adhered to improve the bursting strength. Further, for example, even when the braid lace 1 is cut, fraying from the cut cloth edge can be suppressed. Further, according to the braid lace 1, by regularly forming and arranging the needle loops 20A on the front side of the braid lace 1, the exposure frequency of the needle loops 20A of the insertion yarn 20 can be suppressed. Thereby, in the portion of the braid lace 1 that touches the skin, an extremely sticky feeling of rubber can be suppressed, so that a knitting lace having both flexibility and lace strength can be realized.

[0041] Further, since the elastic yarn 41 and the adhesive yarn 42 are inserted into the basic structure 12 so as to have the same insertion path in the same course direction in the braid lace 1, the transparency is not impaired. The embodiments according to the present invention have been described above, but the present invention is not limited to these, and various changes, additions, etc. are possible without departing from the gist of the invention.

[0042] [Performance Evaluation between Examples and Comparative Examples] The performance of each braid lace of the example and the comparative example was evaluated by conducting a bursting strength test and a washing resistance test. First, the configurations of the example and the comparative example will be described. The braid lace of the present example (hereinafter referred to as the example) and the braid lace of the comparative example (hereinafter referred to as the comparative example) are braided by the same front jacquard machine and are braid laces having the same pattern. The details of each braid lace will be described below. The example is formed by inserting, in order from the front side of the lace knitting, a heat-sealable polyurethane elastic yarn A of 44 dtx, a jacquard yarn of 44 dtx and a pattern yarn of 78 dtx or more and 156 dtx or less, and a polyurethane elastic yarn of 78 dtx and a heat-sealable polyurethane elastic yarn B of 44 dtx into a basic structure in which a plurality of chain stitches are continuous with a chain knitting yarn that is a nylon yarn of 44 dtx. The heat-sealable polyurethane elastic yarn A located on the front side of the lace knitting forms needle loops in every other stitch among the plurality of chain stitches included in the basic structure. The polyurethane elastic yarn and the heat-sealable polyurethane elastic yarn B located on the back side of the lace knitting are inserted so as to have the same insertion path in the course direction of the same basic structure. Then, heat treatment is performed, and the heat-sealable polyurethane elastic yarn is fused to other yarns. In this way, the lace knitting of the example is obtained. The comparative example is formed by inserting, in order from the front side of the lace knitting, a jacquard yarn of 44 dtx and a pattern yarn of 78 dtx or more and 156 dtx or less, and a heat-sealable polyurethane elastic yarn of 156 dtx into a basic structure in which a plurality of chain stitches are continuous with a chain knitting yarn that is a nylon yarn of 44 dtx. Then, heat treatment is performed, and the heat-sealable polyurethane elastic yarn is fused to other yarns. In this way, the lace knitting of the comparative example is obtained. The comparative example does not include a yarn corresponding to the heat-sealable polyurethane elastic yarn A located on the front side of the lace knitting of the example, and accordingly, does not include needle loops formed by the heat-sealable polyurethane elastic yarn A either.

[0043] Next, the test methods and test results in the bursting strength test and the washability test will be described. [Bursting Strength Test] FIG. 6 is a table illustrating the test right results of measuring the strength against bursting of the lace knitting with a pattern. (Test Purpose) Compare and evaluate the bursting strength of each lace knitting of the example and the comparative example. (Test Method) The test method uses a Mullen bursting strength tester of the analog type manufactured by Daiei Kagaku Seiki Co., Ltd. In each fabric of the examples and comparative examples, a predetermined pattern motif at corresponding positions is selected, and the bursting strength is measured at seven corresponding positions in the selected pattern motif. The measured value is the value obtained by subtracting the rubber film pressure from the pressure gauge value after measurement. (Test Results) As illustrated in Fig. 6, in the examples, the measured values were in the range of 223 kPa or more and 290 kPa or less, and the average value thereof was 250 kPa. In the comparative examples, the measured values were in the range of 207 kPa or more and 257 kPa or less, and the average value thereof was 234 kPa. From these results, it was confirmed that the examples had an improved bursting strength of 16 kPa on average compared to the comparative examples. Also, at the weakest part of the bursting strength, the sixth measured value in the examples was 223 kPa, while the sixth measured value in the comparative examples was 207 kPa, so it was confirmed that the bursting strength was still improved.

[0044] [Washing Fastness Test] (Test Purpose) Compare and evaluate the fraying condition of the cut ends of each fabric of the examples and comparative examples. (Test Method) The test method uses a household two-layer washing machine (model number VH30S) manufactured by Toshiba Corporation, and performs a washing process of the fabric for 15 minutes × 20 times (continuous 300 minutes) and a drying process of hanging the washed fabric to dry, and visually checks the fraying condition of the cut ends of each fabric of the examples and comparative examples. The washing fastness test was carried out by a public inspection agency. (Test Results) In the examples, no fraying from the cut ends was visually observed, while in the comparative examples, fraying from the cut ends was visually observed. From these results, it was confirmed that the needle loops formed by the heat-sealable polyurethane elastic yarn located on the front side of the fabric suppressed fraying.
