In other words, the second stitch 15 is a chain stitch that does not include the needle loop 20A and includes only the needle loop 10A. In the second stitch 15 of this example, the insertion yarn 20 is positioned inside the sinker loop formed by the chain knitting yarn 10 or outside the sinker loop. In the second stitch 15 of this example, the insertion yarn 20 is inserted into a sinker loop formed by the chain knitting yarn 10, and the inserted insertion yarn 20 and the sinker loop are bonded at a contact point. Further, the second stitch 15 is a chain stitch at a position where the run stopper portion 100 is not provided.

Further, the insertion thread 20 is, for example, a primarily adhesive thread, a primarily non-adhesive thread, or an adhesive and stretchable thread. The insertion thread 20 is, for example, a heat-fusible thread or a heat-bonding thread when it is primarily an adhesive thread. Adhesive threads are threads made of materials that adhere to other threads, such as heat-fusible threads that melt and deform when heated and bond to other threads, and threads that adhere to other threads when heated. Contains thermal bonding thread that deforms and adheres to fit into the unevenness of the surface.
Furthermore, when the insertion yarn 20 is mainly a non-adhesive yarn, for example, it is a chemical fiber yarn, a natural fiber yarn, or a composite yarn containing at least one of these. Chemical fiber threads include, for example, polyurethane elastic threads (so-called spandex), nylon, or polyester threads. (sometimes also called). Furthermore, the natural fiber threads include threads made of cotton, silk, wool, or the like. Further, the composite yarn containing at least one of these is a yarn containing at least one of a polyurethane elastic yarn, a chemical fiber yarn such as nylon or polyester, and a natural fiber yarn such as cotton, silk, or wool.

Further, the insertion thread 20 is preferably a thread having relatively frictional force, such as a polyurethane elastic thread or a composite thread containing a polyurethane elastic thread. Polyurethane elastic thread is a thread that has both anti-slip properties and stretchability, and it prevents the thread from coming off and contributes to the stretchability of the fabric.
In addition, when the insertion thread 20 is an adhesive and stretchable thread, it is a thread made of a heat-fusible and stretchable material, such as a heat-fusible polyurethane elastic thread ( , polyurethane elastic threads with heat-fusible properties are sometimes called polyurethane adhesive threads). Further, the insertion yarn 20 may be a composite yarn containing an elastic yarn that expands and contracts in the length direction of the yarn, for example, it may be a composite yarn in which an elastic core yarn is coated with a covering yarn.
The insertion yarn 20 in this example is a heat-fusible polyurethane elastic yarn that is heat-fusible and stretchable, and is more stretchable than the chain knitting yarn 10. The heat-sealed insertion thread 20 includes at least a portion where the thread is continuous. The insertion thread 20 may include only a continuous portion of this thread, or may include a continuous portion of this thread and a portion where this thread breaks. The insertion thread 20 of this example includes a portion where the thread is generally continuous.

The functional insertion yarn 40 is an insertion yarn with excellent functionality inserted into the chain stitch of the basic structure 12 formed by the chain stitch yarn 10. The functional insertion yarn 40 of this example is inserted into a plurality of chain stitches in each basic tissue 12 (12A to 12D in FIG. 2) in the course direction. The functional insertion thread 40 includes at least one of an elastic thread 41, an adhesive thread 42, and a functional thread 43. The functional insertion yarn 40 may include all of the elastic yarn 41 , the adhesive yarn 42 , and the functional yarn 43 inserted into the chain stitch of the basic tissue 12 , or any of the elastic yarn 41 , the adhesive yarn 42 , and the functional yarn 43 may be inserted into the chain stitch of the basic tissue 12 . Two may be selected and inserted, or one of the elastic thread 41, the adhesive thread 42, and the functional thread 43 may be selected and inserted. In the functional insertion yarn 40 of this example, two of the elastic yarn 41 and the adhesive yarn 42 are selected and inserted into the chain stitch of the basic tissue 12.

The elastic thread 41 is an example of the second insertion thread according to the present invention, and is an elastic thread that expands and contracts in the length direction of the thread. The elastic thread 41 is, for example, a polyurethane elastic thread (so-called spandex), which is a polyurethane elastic thread that does not have heat fusibility (note that the polyurethane elastic thread that does not have heat fusibility is a polyurethane elastic thread). (sometimes also called). The elastic thread 41 of this example stretches and contracts the basic tissue 12 in the course direction. As a result, the elastic yarn 40 imparts elasticity to the ground fabric 2, making it possible to make the knitted lace 1 a stretch lace.

The adhesive thread 42 is an example of the second insertion thread according to the present invention, and is a thread formed from an adhesive material, specifically, a heat-fusible material. The adhesive thread 42 exhibits an adhesive function with other threads when the material is melted by heat. In addition, the adhesive thread 42 may be an elastic adhesive thread that stretches in the length direction of the thread in addition to being heat-fusible, and the adhesive thread 42 in this example is a heat-fusible polyurethane elastic thread. be. Further, the adhesive thread 42 may be a composite thread containing an elastic thread that expands and contracts in the length direction of the thread, for example, a composite thread in which an elastic core thread is coated with a covering thread. The heat-sealed adhesive thread 42 includes at least a portion where the thread is continuous. The adhesive thread 42 may include only a continuous portion of this thread, or may include a continuous portion of this thread and a portion where this thread breaks. The adhesive thread 42 of this example includes a portion where the thread is generally continuous.

The functional yarn 43 is an example of the second inserted yarn according to the present invention, and is a yarn mainly made of functional fibers that provide a warm touch sensation, a cool touch sensation, or antibacterial and deodorizing properties. The functional yarn 43 is a single-material yarn or a composite yarn, such as acrylic fiber yarn as a warm-sensing functional fiber yarn, cupra fiber yarn as a cold-sensing functional fiber yarn, or other purposes such as antibacterial and deodorizing purposes. It may also be a composite yarn made by appropriately combining materials depending on the effect.

The jacquard yarn 50 is an example of the third inserted yarn according to the present invention, and is inserted into the chain stitch of the basic structure 12 formed by the chain stitch yarn 10, and connects two adjacent basic structures 12 to form a lace pattern. This is an inserted thread forming a ground structure 2 with a . Jacquard yarn 50 is located between insertion yarn 20 and insertion yarn 40.
The jacquard yarn 50 is a single material yarn or a composite yarn, and 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 recycled fiber. Moreover, when the jacquard yarn 50 is a composite yarn, it is, for example, a composite yarn of natural fibers or regenerated fibers and synthetic fibers, or a composite yarn of synthetic fibers. Here, the natural fibers are, for example, cotton, hemp, silk, or wool, and the recycled fibers are, for example, rayon, cupro, polynosic, or the like. Further, the synthetic fibers include, for example, acrylic, polyester, nylon, or polyurethane.
Further, the jacquard yarn 50 may be a heat-sealable adhesive yarn, such as a polyurethane adhesive yarn or a composite yarn in which a polyurethane elastic yarn is used as a core yarn and a nylon yarn is coated. Thereby, fraying and tearing of the ground structure 2 can be prevented. As the composite method for the jacquard yarn, any known composite method such as covering, air entangling, or twisting can be selected as appropriate, and the composite yarn is manufactured by the above composite method suitable for the conditions.
Further, the jacquard yarn 50 may be a yarn mainly made of functional fibers such as a warm touch sensation, a cool touch sensation, or an antibacterial and deodorizing functional fiber yarn. The fiber yarn may be, for example, a cupra fiber yarn, or a composite yarn made by appropriately combining materials depending on the purpose and effect to be added, such as antibacterial and deodorizing properties.

The pattern yarn 60 is inserted into the chain stitch of the basic structure 12 formed by the chain knitting yarn 10, and connects two adjacent basic structures 12 to form a lace pattern or pattern. The pattern yarn 60 is located on the front side of the knitted lace 1 and forms the pattern portion 6 by forming a predetermined pattern. The pattern yarn 60 is woven into the ground structure 2 illustrated in FIG. 1 to form the pattern portion 6. The knitted pattern threads cause the outline, shading, or unevenness of the pattern motif to appear on the ground texture 2, depending on the thickness and density of the pattern per unit area.

FIG. 3 is a diagram illustrating details of the knitting structure of the patterned knitted lace 1.
FIG. 4 is a cross-sectional view illustrating details of the knitting structure of the patterned knitted lace 1.
Note that, for convenience of explanation, spaces are provided between the threads, but in reality the threads are in close contact with each other.
As illustrated in FIG. 3, the insertion yarn 20 is inserted into the basic structure 12 in the course direction of the chain stitch structure 12, and regularly provides needle loops 20A in some of the stitches. Here, among the stitches of the basic structure 12, the stitch including the needle loop 20A formed by the insertion 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 tissue 12 in the course direction of the chain stitch structure 12. Moreover, the jacquard yarn 50 or the pattern yarn 60 connects two adjacent basic structures 12 in the wale direction of the chain stitch structure 12.
The chain stitch structure 12 is formed by arranging a plurality of sets of three stitches, ie, the first stitch 14 of the first stitch and the second stitch 15 of the second stitch, in the course direction. The first stitches 14 and the second stitches 15 are arranged at intervals of every second stitch. Therefore, the needle loops 20A are arranged at intervals of every second stitch. That is, the needle loop 20A is provided in a part of the chain stitches of the chain stitch structure 12 in which the first stitches 14 and the second stitches 15 are regularly arranged. Further, in the first stitch 14, the chain knitting yarn 10 and the insertion yarn 20 are formed such that the needle loop 10A of the chain knitting yarn 10 and the needle loop 20A of the insertion yarn 20 overlap. Therefore, even if the insertion yarn 20 is a non-adhesive yarn, fraying is reduced due to the tightening due to the difference in tension between the chain knitting yarn 10 and the insertion yarn 20 and the resulting frictional resistance. In addition, when the insertion thread 20 is an adhesive thread, other threads are bonded to each other via the insertion thread 20, which further reduces fraying.
In addition, the chain stitch structure 12 of this example will be described with reference to a case where the first stitches 14 of the first stitch are arranged periodically, but the present invention is not limited to this. They may be arranged periodically. Furthermore, the insertion yarn 20 may be arranged in a combination of a first stitch 14 and a plurality of consecutive first stitches 14.

FIG. 4 is a cross-sectional view illustrating details of the knitting structure of the patterned knitted lace 1.
As illustrated in FIG. 4, the stitches of the chain stitch structure 12 are formed by needle loops 10A located on the front side of the knitted lace 1 and sinker loops 10B located on the back side of the knitted lace 1 in the thickness direction of the knitted lace 1. It is formed. Then, the insertion yarn 20, the insertion yarn 40, the jacquard yarn 50, and the pattern yarn 60 are inserted into the stitches of the chain knitting yarn 10.
The insertion thread 20 is located on the front side of the knitted lace 1 from the jacquard thread 50 and the pattern thread 60, and the functional insertion thread 40 is located on the back side of the knit lace 1 from the jacquard thread 50 and the pattern thread 60. The jacquard yarn 50 and the pattern yarn 60 are located between the insertion yarn 20 and the insertion yarn 40.
In this way, in the knitted lace 1, by regularly providing the needle loops 20A in some of the stitches, the openwork feeling can be improved and fraying can be prevented. Furthermore, the knitted lace 1 suppresses the frequency of exposure of the needle loop 20A of the insertion yarn 20 in the first stitch 14 on the front side of the knitted lace 1. This makes it possible to suppress the extremely sticky feeling of the rubber in the part of the knitted lace 1 that comes into contact with the skin.

Next, a method for manufacturing the knitted lace 1 will be described with reference to FIG.
FIG. 5 is a flowchart illustrating the method for manufacturing the patterned knitted lace 1 (S10).
The knitted lace 1 of this 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 knitted lace 1 is obtained by knitting a lace fabric using the front jacquard machine, dyeing the knitted lace fabric, and heat-treating the dyed lace fabric. In this example, knitting is performed using a front jacquard machine, but the knitting is not limited to this, and a back jacquard machine or the like can also be used.

As illustrated in FIG. 5, in step 100 (S100), the operator guides the chain stitch yarn 10 to the knitting needles using a ground reed to form a chain stitch for warp knitting, and consecutively creates a plurality of formed chain stitches in the course direction. In this way, a plurality of basic tissues 12 are formed. A plurality of basic structures 12 to be formed are arranged in parallel at equal intervals in the wale direction. Further, the chain knitting yarn 10 is passed across at a cycle of three courses, and a run stopper part 100 is inserted to connect two adjacent basic structures 12.

In step 102 (S102), the operator causes the front jacquard machine to insert the insertion yarn 20 into the chain stitches of the basic structure 12 formed of the chain stitch yarn 10 in the course direction, form the needle loop 20A, and The first stitch is 14.

In step 104 (S104), the operator causes the front jacquard machine to form second needle loops 20A in chain stitches at regular positions from the first stitch 14 that formed the needle loops 20A. As illustrated in FIG. 3, the operator selects the first stitch 14 in which the needle loop 20B is formed in the chain stitch located every two second stitches 15 from the first stitch 14 in which the needle loop 20A is arranged. will be established.

In step 104 (S104), the operator causes the front jacquard machine to insert the insertion yarn 40 into the chain stitch of the basic structure 12 in the course direction. As illustrated in FIGS. 2 and 3, the elastic thread 41 and the adhesive thread 42 are at least partially arranged along the same insertion path in the course direction of the same basic tissue 12. The elastic thread 41 and adhesive thread 42 of this example are arranged so that they all have the same insertion path. Specifically, the elastic yarn 41 and the adhesive yarn 42 have the same chain stitch as the insertion source chain stitch and the insertion destination chain stitch, and the length of the yarn from the insertion source chain stitch to the insertion destination chain stitch is the same. They have the same route and are generally arranged to run parallel to each other. Note that the elastic thread 41 and the adhesive thread 42 may have insertion paths that intersect with each other.

In step 106 (S106), the operator causes the front jacquard machine to insert the jacquard yarn 50 and pattern yarn 60 into the chain stitches of the basic structure 12 in the course direction. As a result, the operator forms the watermark portion 4, background pattern 5, and pattern portion 6 illustrated in FIG. Among the plurality of jacquard threads 50 inserted into the basic tissue 12, two adjacent jacquard threads 50 are, for example, symmetrical at least in part, and at least in part overlap or intersect with each other. May be placed.
In this manner, 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 a lace fabric before dyeing is manufactured.

In step 108 (S108), the operator dyes the knitted lace fabric. In this example, piece-dyed yarn will be explained, but the yarn is not limited to this, yarn-dyed yarn may be used, and this step can be omitted if the yarn is spun-dyed.

In step 110 (S110), the operator performs a heat treatment to heat the insertion thread 20 and adhesive thread 42 of the lace fabric at a temperature that melts them (heat setting step). The heat setting conditions during the heat setting step are, for example, at a temperature of 160° C. or higher and 200° C. or lower for 90 seconds or less, preferably at 180° C. or higher and 190° C. or lower for 40 seconds or more and 80 seconds or less. The insertion thread 20 and adhesive thread 42 are melted by the heat setting process. The molten insertion yarn 20 and the adhesive yarn 42 are partially broken at a continuous portion, and the molten portion is attached to the chain knitting yarn 10, the jacquard yarn 50, and the pattern yarn 60. As a result, in the first stitch 14, the needle loop 20A of the insertion yarn 20 is bonded to the needle loop 10A of the chain knitting yarn 10. Further, in the second stitch 15, the insertion yarn 20 is bonded to the chain knitting yarn 10 at a position where it is inserted through the sinker loop of the chain knitting yarn 10 and at a position where it contacts the sinker loop. Thereby, the worker can obtain the knitted lace 1 illustrated in FIG. 1.

As explained above, according to the knitted 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 stitch yarn 10 and the insertion yarns 20A are arranged regularly. By adhering the thread 20 to the needle loop 20A, bursting strength can be improved. Further, for example, even when the knitted lace 1 is cut, fraying from the cut edges of the cloth can be suppressed.
Further, according to the knitted lace 1, by regularly forming and arranging the needle loops 20A on the front side of the knitted lace 1, the frequency of exposure of the needle loops 20A of the insertion yarn 20 can be suppressed. This makes it possible to suppress the extremely sticky feeling of the rubber in the part of the knitted lace 1 that comes into contact with the skin, thereby making it possible to realize a knitted lace that has both flexibility and lace strength.

Furthermore, in the knitted lace 1, the elastic yarn 41 and the adhesive yarn 42 are inserted into the basic tissue 12 in the same course direction and along the same insertion path, so that the transparency is not impaired.
Although the embodiments according to the present invention have been described above, the embodiments are not limited to these, and various changes and additions can be made within the scope of the spirit of the invention.

[Performance evaluation of Examples and Comparative Examples]
The performance of each knitted lace of Examples and Comparative Examples was evaluated by performing a bursting strength test and a washing resistance test.
First, the configurations of an example and a comparative example will be explained.
The knitted lace of this example (hereinafter referred to as an example) and the knitted lace of a comparative example (hereinafter referred to as a comparative example) are knitted laces that are knitted by the same front jacquard machine and have the same pattern. The details of each race will be explained below.
In the example, a 44 dtx heat-fusible polyurethane elastic yarn A, a 44 dtx jacquard yarn and It is formed by inserting a pattern yarn of 78 dtx or more and 156 dtx or less, a polyurethane elastic yarn of 78 dtx, and a heat-fusible polyurethane elastic yarn B of 44 dtx. The heat-fusible polyurethane elastic yarn A located on the front side of the knitted lace forms needle loops in every second stitch among the plurality of chain stitches included in the basic structure. The polyurethane elastic yarn and the heat-fusible polyurethane elastic yarn B located on the back side of the knitted lace are inserted so that they all follow the same insertion path in the course direction of the same basic structure. Then, heat treatment is performed, and the heat-fusible polyurethane elastic yarn is fused to other yarns. In this way, the knitted lace of the example was obtained.
In the comparative example, a 44 dtx jacquard yarn, a pattern yarn of 78 dtx or more and 156 dtx or less, and a 156 dtx heat were applied to a basic structure in which a plurality of chain stitches are continuous using a chain stitch yarn that is a 44 dtx nylon yarn. It is formed by inserting fusible polyurethane elastic threads. Then, heat treatment is performed, and the heat-fusible polyurethane elastic yarn is fused to other yarns. In this way, a knitted lace of a comparative example was obtained. The comparative example does not have a yarn corresponding to the heat-fusible polyurethane elastic yarn A located on the front side of the knitted lace of the example, and accordingly, the needle loop formed of the heat-fusible polyurethane elastic yarn A is It is not equipped either.

Next, the test methods and test results for the bursting strength test and the washing resistance test will be explained.
[Bursting strength test]
FIG. 6 is a table illustrating the test results of measuring the burst resistance of patterned knitted lace.
(Test purpose)
The bursting strength of each knitted lace of Examples and Comparative Examples will be compared and evaluated.
(Test method)
The test method was to use a Mullen type bursting strength tester (analog type) manufactured by Daiei Kagaku Seiki Seisakusho Co., Ltd., and test the predetermined pattern motifs at corresponding positions on each lace of the example and comparative example. The burst strength is measured at seven mutually corresponding positions in the selected pattern motif. Note that the measured value is the value obtained by subtracting the rubber membrane pressure from the pressure count value after measurement.
(Test results)
As illustrated in FIG. 6, in the example, measured values ranged from 223 kPa to 290 kPa, and the average value of these values was 250 kPa. Further, in the comparative example, measured values were in the range of 207 kPa or more and 257 kPa or less, and the average value of these was 234 kPa. From these results, it was confirmed that the example had an improved bursting strength of 16 kPa on average compared to the comparative example. In addition, in the part where the bursting strength is the weakest, the measured value at the 6th point in the example is 223 kPa, whereas the measured value at the 6th point in the comparative example is 207 kPa, so the bursting strength will continue to improve. You can confirm that you are doing so.

[Washing resistance test]
(Test purpose)
Compare and evaluate the degree of fraying at the cut edges of each knitted lace in Examples and Comparative Examples.
(Test method)
The test method was to wash the knitted lace for 15 minutes x 20 times (300 minutes continuously) using a household double-layer washing machine (model number VH30S) manufactured by Toshiba Corporation, and then to wash the knitted lace after washing. A drying process of hanging the laces to dry was carried out, and the degree of fraying at the cut ends of each knitted lace of Examples and Comparative Examples was visually confirmed. Note that the washing resistance test was conducted at an official testing agency.
(Test results)
In the example, no fraying from the cut edge was visually observed, whereas in the comparative example, fraying from the cut edge was visually observed. As a result, the needle loops formed by the heat-fusible polyurethane elastic yarns located on the front side of the knitted lace suppress fraying.
