[Figure 2] This is an illustrative example to explain the knitting structure of patterned lace 1. [Figure 3] This is a diagram illustrating the structure of the elastic composite yarn 25. [Figure 4] This figure illustrates the elastic thread 20 and elastic composite thread 25 inserted into the basic tissue 12. [Figure 5]This is a magnified photograph comparing the reverse side of this embodiment with that of a conventional patterned knitted lace 1. [Figure 6] This is a diagram illustrating the manufacturing method (S10) of the braided lace 1. [Modes for carrying out the invention]

[0013] First, let me explain the background to the present invention. Patent Document 1 (Japanese Patent Publication No. 2014-95169) proposes achieving a soft texture by alternating between knitted and bypassed sections of elastic coated yarn. However, the aforementioned invention has physical problems: the bypassed sections of the coated elastic yarn create fine irregularities on the surface of the lace fabric, making it difficult to clearly express the motif; and the elastic threads of the coated elastic yarn tend to come loose due to external forces such as wearing and washing when the product is made. Furthermore, Patent Document 2 (Japanese Patent Publication No. 2015-86502) proposes knitting together an elastic coated elastic yarn and a heat-fusible yarn to achieve a soft feel and prevent the inserted yarn from coming loose. In the above invention, the amount of coated elastic yarn fed in greatly affects the stretch and fit of the lace fabric itself, the so-called kickback, and in order to obtain the desired stretch and kickback, it may be necessary to knit the lace fabric with a high tension on the coated elastic yarn (a low amount of coated elastic yarn fed in), which has the problem of reducing the annular napping effect of the coated yarn. Furthermore, Patent Document 3 (Japanese Patent Publication No. 7-54247) proposes achieving a soft texture by knitting in pile-forming yarn in addition to elastic yarn and then performing a napping treatment. However, the above invention has the problem of concerns about yarn breakage in the base knitting yarn due to the napping treatment, and the production cost being increased because a separate napping treatment is required. Therefore, focusing on the above circumstances, we have created an embodiment of the present invention. According to the embodiment of the present invention, it is possible to provide knitted lace that has low production loss, a pleasant feel on the back of the lace, and does not lose its transparency. Below, a patterned knitted lace 1 according to such an embodiment of the present invention will be described with reference to the drawings.

[0014] 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, the configuration of the patterned knitted lace 1 will be described with reference to Figures 1 to 3. Figure 1 is a photograph illustrating the front side of the patterned knitted lace 1 in the present embodiment. As illustrated in Figure 1, the patterned knitted lace 1 (hereinafter referred to as the knitted lace 1) is, for example, a raschel lace of a warp knitted fabric knitted by a warp knitting machine such as a raschel machine, in which a plurality of through holes are formed, and a lace pattern is formed by a combination of the shape and arrangement of each through hole. The knitted lace 1 has a ground stitch structure 2 and a pattern portion 6 knitted into the ground stitch structure 2.

[0015] The ground stitch structure 2 is a ground stitch structure formed by connecting two adjacent basic structures (a basic structure 12 to be described later) to each other. The ground stitch structure 2 is, for example, a ground stitch structure formed by connecting basic structures formed by chain stitch, tulle, power net or the like to each other. In this example, the basic structures 12 formed by chain stitch are connected to each other to form a chain stitch structure. The chain stitch structure may or may not have a run-stopping (fray-preventing) structure. Further, the ground stitch structure 2 includes an openwork portion 4 and a ground pattern 5. The openwork portion 4 is a region where the amount of yarn arranged per unit area is sparse, and through holes that are various plural mesh openings are arranged therein. The ground pattern 5 is a region where the amount of yarn arranged per unit area is dense, and is formed into a predetermined pattern. The ground pattern 5 in this example forms a 4-course net. The pattern portion 6 is a region on the front side of the ground stitch structure 2, where pattern yarns are knitted into the ground pattern 5 to decorate the ground pattern 5. The pattern portion 6 makes the outline, shading, or unevenness of the floral pattern appear according to the sparsity and density of the knitted pattern yarns.

[0016] Figure 2 is an illustrative diagram for explaining the knitting structure of the patterned knitted lace 1. As illustrated in Figure 2, the knitted lace 1 has chain stitch yarns 10, elastic yarns 20, elastic composite yarns 25, and jacquard yarns 30 that form the ground stitch structure 2, and pattern yarns (not shown) that form the pattern portion 6.

[0017] The chain stitch yarn 10 is an example of a structure-forming yarn according to the present invention, and is a knitting yarn that forms the basic structure 12 which forms the basis of the ground knit structure 2. Here, the basic structure 12 is a structure in which multiple stitches into which an insertion yarn is inserted are continuous, for example, a chain stitch structure, a tulle structure, or a power net knit structure, and the basic structures 12A to 12D in this example are chain stitch structures in which multiple chain stitches are continuous. In other words, the chain stitch yarn 10 is a knitting yarn that forms multiple stitches into which an insertion yarn is inserted. Furthermore, the chain stitch yarn 10 is a yarn made of synthetic fibers among chemical fibers, and is either a filament yarn or a composite yarn. For example, if the chain stitch yarn 10 is a filament yarn, it is made of polyamide nylon (nylon), acrylic, or polyester. Furthermore, if the chain stitch yarn 10 is a composite yarn, for example, it is a heat-fusible yarn, and is a composite yarn in which polyurethane, which is a heat-fusible elastic yarn, is used as the core yarn and a covering yarn, which is a nylon yarn, is wound around it. In this example, the chain stitch yarn 10 is a multifilament yarn made of nylon. The thickness of the chain stitch yarn 10 is, for example, in the range of 20 denier to 140 denier, preferably 30 denier to 40 denier. In this example, the thickness of the chain stitch yarn 10 is 40 denier. The compounding method for the chain stitch yarn 10 can be, for example, covering, air entanglement, or twisting, or any other known compounding method can be appropriately selected, and the chain stitch yarn 10 is a compound yarn manufactured by the above compounding method suitable for the conditions.

[0018] The elastic yarn 20 is an example of the first insertion yarn according to the present invention, and is an insertion yarn that imparts elasticity to the knitted lace 1. The elastic yarn 20 is inserted into the chain stitches of the basic structure 12 while tension is applied by adjusting the amount of yarn fed out. In this example, the elastic yarn 20 is placed in each basic structure 12 and is positioned in a direction (course direction) in which multiple chain stitches into which the insertion yarn is inserted are consecutive. Furthermore, the elastic yarn 20 is an elastic yarn that stretches and contracts. The elastic yarn 20 is, for example, a polyurethane elastic yarn (so-called spandex) or a heat-fusible polyurethane elastic yarn. As a result, the elastic yarn 20 can stretch the basic structure 12 in the course direction, so that the knitted lace 1 can be made into a stretch lace. The thickness of the elastic yarn 20 is, for example, in the range of 40 denier to 560 denier, preferably 70 denier to 280 denier, and the thickness can be appropriately changed depending on the elongation and elastic force. In this example, the thickness of the elastic yarn 20 is 70 denier. The elastic yarn 20 is located on the back side of the knitted lace 1, that is, the side that comes into contact with the skin, as described later with the jacquard yarn 30.

[0019] The elastic composite yarn 25 is an example of a second insertion yarn according to the present invention, and is an insertion yarn that imparts pile to the knitted lace 1. The elastic composite yarn 25 is an insertion yarn that is inserted into the chain stitches of the basic structure 12. In this example, the elastic composite yarn 25 is placed in each basic structure 12 and is arranged in a direction in which multiple stitches into which the insertion yarn is inserted are continuous (course direction). Furthermore, the elastic composite yarn 25 is a composite yarn containing elastic yarn and is therefore stretchable. The detailed composition of the elastic composite yarn 25 will be described later. The elastic composite yarn 25 is located on the back side of the knitted lace 1, that is, the side that comes into contact with the skin, which will be described later, using the jacquard yarn 30.

[0020] The jacquard yarn 30 is an example of a third insert yarn according to the present invention, and is an insert yarn inserted into the chain stitches of the basic structure 12. The jacquard yarn 30 is located on the front side of the knitted lace 1 twisted together with the elastic yarn 20, the elastic composite yarn 25, and the pattern yarn described later. The jacquard yarn 30 connects two adjacent basic structures 12, forming a ground knit structure 2 with a lace pattern. The jacquard yarn 30 is a single-material yarn or a composite yarn, and in this example, it is a composite yarn. Furthermore, the jacquard yarn 30 is, for example, a composite yarn of natural or regenerated fibers and synthetic fibers, or a composite yarn of synthetic fibers. Synthetic fibers include, for example, acrylic, polyester, nylon, or polyurethane. Natural fibers include, for example, cotton, linen, silk, or wool, and regenerated fibers include, for example, rayon, cupro, or polynosic. The jacquard yarn 30 may also be a heat-fusible yarn, for example, a composite yarn in which a heat-fusible elastic yarn such as polyurethane is used as the core yarn and a covering yarn which is a nylon yarn is wound around it. In this example, the jacquard yarn 30 is a composite yarn of cupro fibers and nylon fibers. Cupro fibers have the aforementioned functionalities such as water absorption and moisture absorption and release, which contribute to the comfort of clothing. The compounding method for the jacquard yarn 30 can be appropriately selected from known compounding methods such as covering, air entanglement, or twisting, and the jacquard yarn 30 is a composite yarn manufactured by the above compounding method suitable for the conditions.

[0021] The pattern yarn is an insertion yarn that is inserted into the chain stitches of the basic structure 12. The pattern yarn is located on the front side of the knitted lace 1, which is made from elastic yarn 20, elastic composite yarn 25, and jacquard yarn 30, and forms a predetermined pattern. The pattern yarn is knitted into the background pattern 5 as exemplified in Figure 1 to form the patterned section 6. Depending on the density of the knitted pattern yarn per unit area, the outline, shading, or unevenness of the floral pattern appears in the background pattern 5. Furthermore, the handle thread is a yarn made of synthetic fibers, such as polyamide nylon (nylon), acrylic, or polyester (cationically dyeable polyester). The handle thread can also be made of regenerated fibers such as rayon. In this example, the handle thread is nylon.

[0022] Figure 3 illustrates the structure of the elastic composite yarn 25. Figure 3(A) shows an example of the elastic composite yarn 25 in an unstretched state, and Figure 3(B) shows an example of the elastic composite yarn 25 in an stretched state. As illustrated in Figure 3, the elastic composite yarn 25 includes a core yarn 250 and a covering yarn 252, and is a composite yarn in which the elastic core yarn 250 is covered with the covering yarn 252. The elastic composite yarn 25 in this example is a covering yarn, and specifically a single covering yarn. The core thread 250 is an elastic yarn with elasticity, such as a polyurethane elastic yarn or a heat-fusible polyurethane elastic yarn. In this example, the core thread 250 is a heat-fusible elastic yarn. The covering yarn 252 is a yarn that covers the core yarn 250, and covers the core yarn 250 by wrapping around or entangling it. In this example, the covering yarn 252 covers the core yarn 250 by loosely wrapping around it. The covering yarn 252 is wrapped so as to be movable relative to the outer surface of the core yarn 250 when the core yarn 250 expands or contracts in the axial direction. Even when the core yarn 250 expands or contracts in the axial direction, the covering yarn 252 follows the expanding and contracting core yarn 250 by changing the distance between the outer surface of the core yarn 250 and the outer surface of the covering yarn 252. The covering yarn 252 is, for example, a synthetic fiber such as acrylic, polyester, or nylon; a natural fiber such as cotton, linen, silk, or wool; or a regenerated fiber such as rayon, cupro, or polynosic. In addition, among the above synthetic fibers, natural fibers, and regenerated fibers, there are fibers that can be rephrased as functional fibers. For example, yarns that fall under the categories of moisture-absorbing and quick-drying / moisture-absorbing and releasing functional fibers, contact-cooling functional fibers, heat-shielding and UV-cut functional fibers, heat-retaining functional fibers, moisture-absorbing and heat-generating functional fibers, or deodorizing functional fibers can be referred to as functional fibers.

[0023] As illustrated in Figure 3(A), when the elastic composite yarn 25 is not stretched and is in its natural state (non-stretched state), the core yarn 250 and the covering yarn 252 include portions that are separated from each other. In these separated portions, the winding circumference of the covering yarn 252 increases in the radial direction of the core yarn 250, resulting in increased bulkiness of the elastic composite yarn 25. Furthermore, the distance between the outer surface of the core yarn 250 and the outer surface of the covering yarn 252 when the elastic composite yarn 25 is in its non-stretched state is longer than the distance between the outer surface of the core yarn 250 and the outer surface of the covering yarn 252 when the elastic composite yarn 25 is stretched (stretched state). In other words, because the covering yarn 252 and the core yarn 250 are relatively separated, a gap H1 is partially formed between the core yarn 250 and the covering yarn 252. Furthermore, as illustrated in Figure 3(B), when the stretchable composite yarn 25 is in an extended state, the winding circumference of the covering yarn 252 becomes smaller in the radial direction of the core yarn 250 compared to when the stretchable composite yarn 25 is not extended, resulting in a reduction in the bulkiness of the composite yarn 25. In other words, the distance between the outer wall surface of the core yarn 250 and the outer wall surface of the covering yarn 252 when the stretchable composite yarn 25 is in an extended state is shorter than the distance between the outer wall surface of the core yarn 250 and the outer wall surface of the covering yarn 252 when the stretchable composite yarn 25 is not extended. That is, the covering yarn 252 and the core yarn 250 are relatively close to each other, so a gap H2 shorter than the gap H1 is formed between the core yarn 250 and the covering yarn 252. Note that when the stretchable composite yarn 25 is in an extended state, the core yarn 250 and the covering yarn 252 are in near contact, so the gap H2 is almost eliminated. Therefore, the elastic composite yarn 25 is inserted into the basic structure 12 in an elongated state, and after the knitting of the ground knit structure 2, when the knitted lace becomes un-elongated due to the contraction force of the elongated elastic yarn 20 trying to return to its natural length, the covering yarn 252 protrudes in a pile-like manner. In this way, the elastic composite yarn 25 can form a pile on the back side of the knitted lace 1 by causing only the covering yarn 252 to protrude on the back side of the knitted lace 1. The elastic composite yarn 25 maintains the formed pile whether the knitted lace is in an elongated or un-elongated state, and as a result, a soft feel can be maintained. In this example, the elastic composite yarn 25 is a covering yarn, but in the compounding method, any known compounding method can be appropriately selected in addition to covering processing, air entanglement processing, or twisting processing, and the composite yarn is manufactured using the above compounding method suitable for the conditions.

[0024] Figure 4 illustrates the elastic thread 20 and elastic composite thread 25 inserted into the basic tissue 12. Figure 4(A) illustrates the state in which the elastic thread 20 and elastic composite thread 25 are inserted through the same insertion route, and Figure 4(B) illustrates the state in which at least a portion of the elastic thread 20 and elastic composite thread 25 are inserted through the same insertion route. As illustrated in Figure 4, the elastic thread 20 and the elastic composite thread 25 are each inserted in the course direction of the basic tissue 12. At least a portion of the inserted elastic thread 20 and elastic composite thread 25 are placed along the same insertion path; for example, they may all be placed along the same insertion path, or only a portion may be placed along the same insertion path. As illustrated in Figure 4(A), the elastic yarn 20 and the elastic composite yarn 25 are all placed along the same insertion path and run parallel to each other overall. The source chain stitch and the destination chain stitch of the elastic yarn 20 and the elastic composite yarn 25 are the same chain stitch, and the yarn path from the source chain stitch to the destination chain stitch is the same. Also, as illustrated in Figure 4(B), the elastic yarn 20 and the elastic composite yarn 25 are partially placed along the same insertion path, including parts where they run parallel to each other and parts where they run separately. In the parts where they run parallel to each other, the source chain stitch and the destination chain stitch of the elastic yarn 20 and the elastic composite yarn 25 are the same chain stitch, and the yarn path from the source chain stitch to the destination chain stitch is the same. Furthermore, in the parts where they run separately, the elastic yarn 20 and the elastic composite yarn 25 are inserted into different chain stitches, either at the source or destination of insertion, and the yarn paths from the source chain stitch to the destination chain stitch are different. Thus, the elastic thread 20 and the elastic composite thread 25 are arranged so that they follow the same course direction and at least a portion of them share the same insertion path. Furthermore, the tissues in which the insertion paths of the elastic thread 20 and the elastic composite thread 25 intersect may also be such. In this example, the elastic thread 20 and the elastic composite thread 25 all follow the same insertion path, running parallel to each other overall.

[0025] Figure 5 is a magnified photograph comparing the reverse side of this embodiment and a comparative patterned knitted lace 1. Figure 5(A) is a magnified photograph illustrating the reverse side of patterned knitted lace 1 of this embodiment, and Figure 5(B) is a magnified photograph illustrating the reverse side of a comparative patterned knitted lace (hereinafter referred to as the comparative lace). The comparative lace has only the elastic yarn 20 inserted, and the elastic composite yarn 25 is not inserted. As illustrated in Figure 5(A), in the unstretched state, the knitted lace 1 has only the covering yarn 252 protruding from the elastic composite yarn 25, so it can be confirmed that there is pile on the reverse side. On the other hand, as illustrated in Figure 5(B), the comparison lace does not have the elastic composite yarn 25, so it can be confirmed that there is no pile on the reverse side. Thus, in this embodiment, the knitted lace 1 is arranged so that the covering yarn 252 is partially separated from the core yarn 250 when not stretched, and the covering yarn 252 protrudes from the back surface of the knitted lace 1, resulting in a lace with a pleasant feel against the skin. Furthermore, because the covering yarn 252 protrudes from the back surface of the knitted lace 1, the functionality of the functional fiber used in the covering yarn 252 can be more fully exhibited. In this way, by inserting the elastic composite yarn 25 in addition to the elastic yarn 20, frictional resistance is generated between them, and the number of adhesion points between the elastic yarn 20 and the core yarn 250 of the elastic composite yarn 25 is increased, thereby preventing the elastic yarn 20 from coming loose. Furthermore, by adjusting the finished density after knitting, the density setting during knitting, the thickness and amount of elastic yarn 20, the desired elongation and kickback can be achieved. Similarly, by adjusting the amount of elastic composite yarn 25, the protrusion of the covering yarn 252 of the elastic composite yarn 25 can be desired on the back of the knitted lace without compromising transparency, resulting in a lace with a pleasant feel against the skin.

[0026] Next, with reference to Figure 6, the manufacturing method of the knitted lace 1 will be explained. Figure 6 is a diagram illustrating the manufacturing method (S10) of the knitted lace 1. The knitted lace 1 in this embodiment is knitted using a front jacquard raschel knitting machine (hereinafter referred to as a front jacquard machine). In the manufacturing method described below, the knitted lace 1 is knitted using the front jacquard machine, the knitted lace 1 is dyed, and the dyed knitted lace 1 is obtained. As illustrated in Figure 6, in step 100 (S100), the operator causes the front jacquard machine to form the basic structure 12 illustrated in Figure 2. Specifically, the front jacquard machine guides the chain stitch yarn 10 to the knitting needles with the ground reed to form chain stitches for warp knitting, and then forms multiple basic structures 12 by arranging multiple chain stitches in a continuous manner in the course direction. Multiple basic structures 12 are formed and are provided at equal intervals in the wale direction.

[0027] In step 102 (S102), the operator causes the front jacquard machine to insert the elastic yarn 20 into the chain stitches of the formed basic structure 12. In this example, the front jacquard machine inserts the elastic yarn 20 into all the chain stitches in the direction of the course where multiple chain stitches are continuous. At this time, the kickback (the force that returns to its original state from a stretched state) can be appropriately adjusted by adjusting at least one of the period, thickness, and amount of yarn fed for inserting the elastic yarn 20 into the chain stitches, according to the target elongation of the lace.

[0028] In step 103 (S103), the operator causes the front jacquard machine to insert the elastic composite yarn 25 into the chain stitches of the formed basic structure 12. In this example, the front jacquard machine inserts the elastic composite yarn 25 into all the chain stitches in the direction of the course where multiple chain stitches are continuous. Specifically, as illustrated in Figure 2, the front jacquard machine inserts the elastic yarn 20 and the elastic composite yarn 25 so that they run parallel to each other and all follow the same insertion path. At this time, by adjusting at least one of the period for inserting the elastic composite yarn 25 into the chain stitches and the amount of yarn fed for each, in accordance with the target elongation of the lace, the gap H1 between the core yarn 250 and the covering yarn 252, as illustrated in Figure 3(A), that is, the amount of pile protrusion formed by the covering yarn 252, can be appropriately adjusted.

[0029] In step 104 (S104), the operator causes the front jacquard machine to form the pattern section 6 as illustrated in Figure 1. Specifically, the front jacquard machine inserts pattern yarn into the chain stitches of the formed basic structure 12, forming a floral pattern on the back side of the knitted lace 1 using the jacquard yarn 30.

[0030] In step 106 (S106), the operator causes the front jacquard machine to form the base knitting structure 2 as illustrated in Figure 1. Specifically, as illustrated in Figure 2, the front jacquard machine inserts the jacquard yarn 30 guided from the jacquard reed into the chain stitches of the base knitting structure 12, and connects two adjacent base knitting structures 12 from among the multiple base knitting structures 12 arranged in the wale direction at the front side of the knitted lace made from elastic yarn 20 and elastic composite yarn 25 to form the base knitting structure 2. The front jacquard machine connects the wales of the two adjacent base knitting structures 12 with the jacquard yarn 30 and also forms the openwork section 4 and the base pattern 5 as illustrated in Figure 1. In this way, in steps S100, S102, S103, S104, and S106 above, knitting and other processes are carried out on the same course using the knitting operation of the front jacquard knitting machine, and knitted lace before dyeing is produced. In this example, knitting was done using a front jacquard machine, but this is not limited to that. It is sufficient that the elastic yarn 20 and the elastic composite yarn 25 are located on the back side of the knitted lace 1 compared to the jacquard yarn 30 and the pattern yarn, and it can also be achieved using a so-called back jacquard machine, where the insertion positions of S104 and S106 are reversed.

[0031] In step 108 (S108), the worker dyes at least one of the patterned section 6 and the base knitted structure 2 of the knitted lace (post-dyeing). The selection of dyes depends on the material used; for example, acid dyes are selected when dyeing nylon yarn, reactive dyes or direct dyes are selected when dyeing cotton, rayon, and cupro, and cationic dyes are selected when dyeing cationic dyeable polyester to achieve the desired color scheme. In some cases, no color is added during scouring or other processes. Thus, this manufacturing method makes it possible to produce knitted lace in which elastic yarn 20 and elastic composite yarn 25 are arranged on the back side of the knitted lace 1 in the thickness direction of the knitted lace. In this manufacturing method, although the post-dyeing case has been described, pre-dyeing is also possible, or knitting with dope-dyed yarn is also possible. Furthermore, the worker performs a heat treatment (heat setting process) in which the core thread 252 of the elastic composite yarn 25 of the dyed knitted lace 1 is melted with heat and the elastic composite yarn 25 is bonded to the elastic yarn 20. During the heat setting process, the elastic composite yarn 25 and the elastic yarn 20 are bonded together, and the desired pitch and width are adjusted to obtain the knitted lace 1 exemplified in Figure 1. The heat setting conditions at that time are a temperature of 160°C to 200°C for 90 seconds or less, preferably a heat treatment of 180°C to 190°C for 40 seconds to 80 seconds.

[0032] As described above, according to the knitted lace 1 of this embodiment, by inserting elastic yarn 20, which provides elasticity to the chain stitches of the basic structure 10, and elastic composite yarn 25, which provides pile, according to their respective roles, the elongation of the lace and the amount of pile protrusion can be appropriately adjusted, resulting in a lace with a better feel against the skin. Furthermore, by inserting the elastic yarn 20 and elastic composite yarn 25 so that they run parallel to each other and all follow the same insertion path, the transparency of the knitted lace 1 is not compromised. Furthermore, since the elastic composite yarn 25 is placed on the back side of the knitted lace 1, the functional effects of the functional fibers used in the covering yarn 252 are more fully realized during use. Although embodiments of the present invention have been described above, the invention is not limited thereto, and various modifications and additions are possible without departing from the spirit of the invention.

[0033] Next, a modified example of the above embodiment will be described. In the modified examples, elements having substantially the same function and configuration as those in the above embodiments are denoted by the same reference numerals, thus omitting redundant explanations. [Example 1] In the above embodiment, the case in which the chain stitch yarn 10 forming the basic structure 12 is made of a single nylon material yarn and the elastic yarn 20 is made of polyurethane elastic yarn was described. However, the invention is not limited to this, and the chain stitch yarn 10 may be made of a composite yarn of heat-fusible polyurethane and nylon, and the elastic yarn 20 may be made of heat-fusible polyurethane elastic yarn. By making the chain stitch yarn 10 and the elastic yarn 20 heat-fusible yarn in this way, it is possible to prevent spindle slippage and fraying. [Explanation of Symbols]
