[Figure 6] 1A to 1C are diagrams illustrating a manufacturing method (S10) of the knitted lace 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] First, the background of the present invention will be described. Patent Document 1 (JP Patent Publication 2014-95169A) proposes alternating between weaving and bypassing stretchy covered elastic yarns to achieve a soft feel. The invention has physical problems, such as the bypassing of the covered elastic yarns causing fine irregularities on the surface of the lace fabric, making it difficult to clearly express the motif, and the covered elastic yarns easily coming loose due to external forces such as wearing and washing after the finished product. Also, Patent Document 2 (JP Patent Publication 2015-86502 A) proposes weaving together stretchable covered elastic yarn and heat-sealed yarn to achieve a soft feel and prevent the inserted yarn from slipping out. In the above invention, the return feeling related to the elongation and fit of the lace fabric itself, or the so-called kickback, is closely related to the amount of covered elastic yarn fed in, and in order to obtain the desired elongation and kickback, it may be necessary to knit the covered elastic yarn into the lace fabric with a high tension (reducing the amount of covered elastic yarn fed in), which poses a problem of reducing the annular raising effect of the covered yarn. In addition, Patent Document 3 (JP Patent Publication 7-54247A) proposes to realize a soft feel by knitting pile-forming yarn in addition to the stretch yarn and then performing a raising process. The above invention has problems such as the concern that the ground knitting yarn may break due to the raising process, and the need to perform a separate raising process, which increases production costs. Therefore, the present invention has been created by focusing on the above-mentioned circumstances. According to the present invention, it is possible to provide a knitted lace with less production loss, a pleasant texture on the back side of the lace, and no loss of transparency. Hereinafter, such a knitted lace with a pattern 1 according to the present invention will be described with reference to the drawings.

[0014] Hereinafter, an embodiment of 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 knit lace 1 will be described with reference to Figs. 1 to 3. FIG. 1 is a photograph illustrating the front side of a patterned knitted lace 1 in this example. As shown in Fig. 1, the patterned knitted lace 1 (hereinafter referred to as knitted lace 1) is, for example, a warp-knitted raschel lace knitted by a warp knitting machine such as a raschel machine, and has a plurality of through holes formed therein, with the lace pattern being formed by the combination of the shape and arrangement of each through hole. The knitted lace 1 has a ground knit structure 2 and a pattern portion 6 knitted into the ground knit structure 2.

[0015] The ground knit structure 2 is a ground knit structure formed by connecting two adjacent basic structures (basic structure 12 described later) to each other. The ground knit structure 2 is a ground knit structure formed by connecting basic structures formed, for example, of chain stitch, tulle, power net, etc., to each other, and in this example, 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 stop (anti-fraying) structure. The ground knit structure 2 also includes an openwork portion 4 and a ground pattern 5. The openwork portion 4 is an area where the amount of threads arranged per unit area is sparse, and through holes, which are a variety of 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 ground pattern 5 in this example forms a four-course net. The pattern portion 6 is an area on the front side of the ground knit structure 2 where pattern yarns are woven into the ground pattern 5 to decorate the ground pattern 5. The pattern portion 6 creates the outline, light and shade, or unevenness of a floral pattern depending on the density of the woven pattern yarns.

[0016] FIG. 2 is an illustrative example for explaining the knitting structure of the patterned knitted lace 1. As shown in FIG. 2, the knitted lace 1 has chain stitch yarn 10, stretch yarn 20, stretchable composite yarn 25, and jacquard yarn 30 which form the ground knit structure 2, and pattern yarn (not shown) which forms the pattern portion 6.

[0017] The chain knit yarn 10 is an example of the knitting yarn according to the present invention, and is a knitting yarn that forms the basic knit 12 that is the basis of the ground knit 2. Here, the basic knit 12 is a knitting yarn in which a plurality of stitches into which an inserting yarn is inserted are continuous, such as a chain knit, tulle, or power net knit. The basic knits 12A to 12D of this example are chain knit structures in which a plurality of chain stitches are continuous. That is, the chain knit yarn 10 is a knitting yarn that forms a plurality of stitches into which an inserting yarn is inserted. The chain knit yarn 10 is a yarn formed of synthetic fibers among chemical fibers, and is a filament yarn or a composite yarn. For example, when the chain knit yarn 10 is a filament yarn, it is formed of polyamide nylon (nylon), acrylic, or polyester. When the chain knit yarn 10 is a composite yarn, it is, for example, a heat-fusible yarn, and is a composite yarn in which a covering yarn that is a nylon yarn is wound around a core yarn of polyurethane that is a heat-fusible elastic yarn. The chain knit yarn 10 in this example is a multifilament yarn made of nylon. The thickness of the chain knit yarn 10 is, for example, in the range of 20 denier to 140 denier, and preferably 30 denier to 40 denier. The thickness of the chain knit yarn 10 in this example is 40 denier. The compounding method of the chain knit yarn 10 can be appropriately selected from known compounding methods such as covering, air entanglement, and ply-twisting, and the chain knit yarn 10 is a compound yarn manufactured by the compounding method suitable for the conditions.

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

[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. The elastic composite yarn 25 of this example is arranged in each basic structure 12, and is arranged in the direction (course direction) in which multiple stitches into which the insertion yarn is inserted are continuous. The elastic composite yarn 25 is a composite yarn containing elastic yarn and is elastic. The detailed configuration 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 relative to the jacquard yarn 30 described later, that is, on the side that comes into contact with the skin.

[0020] The jacquard yarn 30 is an example of a third insertion yarn according to the present invention, and is an insertion 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 relative to the stretch yarn 20, the stretchable composite yarn 25, and a pattern yarn, which will be described later. The jacquard yarn 30 connects two adjacent basic structures 12 to form 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. 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. The synthetic fibers are, for example, acrylic, polyester, nylon, polyurethane, etc. The natural fibers are, for example, cotton, linen, silk, wool, etc., and the regenerated fibers are, for example, rayon, cupra, polynosic, etc. The jacquard yarn 30 may be a heat-fusible yarn, for example, a composite yarn in which polyurethane, which is a heat-fusible elastic yarn, is used as a core yarn and a covering yarn, which is a nylon yarn, is wound around the core yarn. The jacquard yarn 30 in this example is a composite yarn of cupra fiber and nylon fiber. The functionality of the cupra fiber includes water absorption and moisture absorption / release, which makes clothing comfortable. The method of compounding the jacquard yarn 30 can be appropriately selected from known compounding methods such as covering processing, air intertwining processing, and twisting processing, 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 positioned on the front side of the knitted lace 1 by the stretch yarn 20, the stretchable composite yarn 25, and the jacquard yarn 30, and is a yarn that forms a predetermined pattern. The pattern yarn is woven into the ground pattern 5 shown in Fig. 1 to form the pattern portion 6. The woven pattern yarn creates the outline, light and shade, or unevenness of a floral pattern in the ground pattern 5 depending on the density per unit area. The patterned yarn is a yarn made of synthetic fibers, such as polyamide nylon (nylon), acrylic, or polyester (cationically dyeable polyester). The patterned yarn is also a yarn made of regenerated fibers, such as rayon. The patterned yarn in this example is a nylon yarn.

[0022] Fig. 3 is a diagram illustrating the configuration of the elastic composite yarn 25. Fig. 3(A) is a diagram illustrating the elastic composite yarn 25 in a non-stretched state, and Fig. 3(B) is a diagram illustrating the elastic composite yarn 25 in a stretched state. 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, specifically a single covering yarn. The core yarn 250 is a stretchable elastic yarn, for example, a polyurethane elastic yarn or a heat-fusible polyurethane elastic yarn. Note that the core yarn 250 in this example is a heat-fusible elastic yarn. The covering yarn 252 is a yarn covering the core yarn 250, and covers the core yarn 250 by winding or entangling it around the core yarn 250. The covering yarn 252 in this example covers the core yarn 250 by being loosely wound around the core yarn 250. The covering yarn 252 is wound around the core yarn 250 so as to be movable relative to the outer wall surface of the core yarn 250 when the core yarn 250 expands and contracts in the axial direction. Even if the core yarn 250 expands and contracts in the axial direction, the covering yarn 252 follows the expanding and contracting core yarn 250 by changing the distance between the outer wall surface of the core yarn 250 and the outer wall 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, hemp, silk, or wool, or a regenerated fiber such as rayon, cupra, or polynosic. Among the above synthetic fibers, natural fibers, and regenerated fibers, there are fibers that can be called functional fibers. For example, yarns that correspond to water absorbing and quick drying / moisture absorbing and releasing functional fibers, cool to the touch functional fibers, heat shielding and UV blocking functional fibers, heat retaining functional fibers, moisture absorbing and heat generating functional fibers, deodorizing functional fibers, etc. can be referred to as functional fibers.

[0023] As illustrated in Fig. 3(A), when the elastic composite yarn 25 is in an unstretched natural state (unstretched state), the core yarn 250 and the covering yarn 252 include portions that are separated from each other. In the portions that are separated from each other, the winding circumference of the covering yarn 252 becomes larger in the radial direction of the core yarn 250, and as a result, the bulkiness of the elastic composite yarn 25 increases. In addition, the distance between the outer wall surface of the core yarn 250 and the outer wall surface of the covering yarn 252 when the elastic composite yarn 25 is in an unstretched state is longer 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 elastic composite yarn 25 is in a stretched state (stretched state). In other words, the covering yarn 252 and the core yarn 250 are relatively separated from each other, and therefore a gap H1 is partially formed between the core yarn 250 and the covering yarn 252. 3(B), when the elastic composite yarn 25 is in an elongated state, the winding circumference of the covering yarn 252 becomes smaller in the radial direction of the core yarn 250 compared to when the elastic composite yarn 25 is in a non-elongated state, and as a result, the bulkiness of the composite yarn 25 decreases. In other words, when the elastic composite yarn 25 is in an elongated state, the distance between the outer wall surface of the core yarn 250 and the outer wall surface of the covering yarn 252 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 in a non-elongated state. That is, since the covering yarn 252 and the core yarn 250 are relatively close to each other, a gap H2 that is shorter than the gap H1 is formed between the core yarn 250 and the covering yarn 252. Note that when the elastic composite yarn 25 is in an elongated state, the core yarn 250 and the covering yarn 252 are almost in contact with each other, and therefore the gap H2 is almost eliminated. Therefore, the elastic composite yarn 25 is inserted into the basic structure 12 in a stretched state, and when the knitted lace becomes unstretched due to the contractile force of the stretched elastic yarn 20 attempting to return to its natural length after the ground knit structure 2 is knitted, the covering yarn 252 protrudes in a pile shape. In this way, the elastic composite yarn 25 can form pile on the back side of the knitted lace 1 by causing only the covering yarn 252 to protrude from the back side of the knitted lace 1. The elastic composite yarn 25 maintains the formed pile even when the knitted lace is in a stretched or unstretched state, and as a result, a soft feel can be maintained. In addition, the elastic composite yarn 25 in this example is a covering yarn, but the compounding method can be selected appropriately from known compounding processing methods such as covering processing, air entanglement processing, or twisting processing, and the composite yarn is manufactured using the above-mentioned compounding method suitable for the conditions.

[0024] Fig. 4 is a diagram illustrating an example of a stretch yarn 20 and a stretchable composite yarn 25 inserted into a basic weave 12. Fig. 4(A) is a diagram illustrating a state in which the stretch yarn 20 and the stretchable composite yarn 25 are inserted through the same insertion path, and Fig. 4(B) is a diagram illustrating a state in which at least a portion of the stretch yarn 20 and the stretchable composite yarn 25 are inserted through the same insertion path. 4, the elastic yarn 20 and the elastic composite yarn 25 are each inserted in the course direction of the basic weave 12. At least a portion of the inserted elastic yarn 20 and elastic composite yarn 25 are arranged in the same insertion path. For example, there are cases where all of the elastic yarn 20 and the elastic composite yarn 25 are arranged in the same insertion path, and cases where only a portion of the elastic yarn 20 and the elastic composite yarn 25 are arranged in the same insertion path. As shown in FIG. 4(A), the stretch yarn 20 and the stretchable composite yarn 25 are all arranged on the same insertion path and run parallel to each other overall. The chain stitches at the source and the chain stitches at the destination of the stretch yarn 20 and the stretchable composite yarn 25 are the same chain stitches, and the thread path from the source chain stitch to the destination chain stitch is the same. Also, as shown in FIG. 4(B), the stretch yarn 20 and the stretchable composite yarn 25 are partially arranged on the same insertion path and include a portion running parallel to each other and a portion running separately from each other. In the portion running parallel to each other, the chain stitches at the source and the chain stitches at the destination of the stretch yarn 20 and the stretchable composite yarn 25 are the same chain stitches, and the thread path from the source chain stitch to the destination chain stitch is the same. In addition, in the portions where the elastic yarn 20 and the elastic composite yarn 25 run separately from each other, the chain stitches into which they are inserted or the chain stitches into which they are inserted are different from each other, and the paths of the yarn from the chain stitches into which they are inserted are different from each other. In this way, the stretch yarn 20 and the elastic composite yarn 25 are arranged in the same course direction, with at least a portion of them following the same insertion path. The stretch yarn 20 and the elastic composite yarn 25 may also be in a structure in which the insertion paths cross. In this example, the stretch yarn 20 and the elastic composite yarn 25 all follow the same insertion path so as to run parallel to each other overall.

[0025] FIG. 5 is an enlarged photograph comparing the reverse sides of the patterned knitted lace 1 of this embodiment and that of a comparative example. Fig. 5(A) is an enlarged photograph illustrating the back surface of the patterned knitted lace 1 of this example, and Fig. 5(B) is an enlarged photograph illustrating the back surface of a comparative patterned knitted lace (hereinafter, comparative lace). The comparative lace is a lace in which only the elastic yarn 20 is inserted, and no elastic composite yarn 25 is inserted. As shown in Fig. 5(A), in the unstretched state, the knitted lace 1 has only the covering yarn 252 of the elastic composite yarn 25 protruding, and therefore the presence of pile can be confirmed on the back surface. On the other hand, as shown in Fig. 5(B), the comparative lace does not have the elastic composite yarn 25, and therefore the absence of pile can be confirmed on the back surface. Thus, in the unstretched state, the knitted lace 1 of this embodiment can be made to have a pleasant feel, with the covering yarn 252 being arranged so as to be partially separated from the core yarn 250 and protruding from the back surface of the knitted lace 1. Furthermore, since 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 increases, making it possible to prevent the elastic yarn 20 from coming loose. In addition, the desired elongation and kickback can be achieved by adjusting the finished density after knitting and the density setting during knitting, and by the thickness and amount of elastic yarn 20 fed. Similarly, by adjusting the amount of elastic composite yarn 25 fed, the protrusion of covering yarn 252 of elastic composite yarn 25 can be made to appear as desired on the back surface of the knitted lace without impairing the transparency, thereby achieving a lace that is pleasant to the touch.

[0026] Next, a method for manufacturing the knitted lace 1 will be described with reference to FIG. FIG. 6 is a diagram illustrating a manufacturing method (S10) of the knitted lace 1. The knitted lace 1 of this embodiment is knitted by a front jacquard raschel knitting machine (hereinafter, referred to as a front jacquard machine). In the manufacturing method of this embodiment, the knitted lace 1 is knitted using the front jacquard machine, and the knitted knitted lace 1 is dyed to obtain a dyed knitted lace 1. As shown in Fig. 6, in step 100 (S100), an operator causes the front jacquard machine to form the basic structure 12 shown in Fig. 2. Specifically, the front jacquard machine guides the chain stitch yarn 10 to the knitting needles by a ground reed to form chain stitches for warp knitting, and then forms a plurality of basic structures 12 by continuously repeating the formed chain stitches in the course direction. A plurality of basic structures 12 are formed at equal intervals in the wale direction.

[0027] In step 102 (S102), the operator causes the front jacquard machine to insert the stretch yarn 20 into the chain stitches of the formed basic structure 12. In this example, the front jacquard machine inserts the stretch yarn 20 into all the chain stitches in the course direction in which a plurality of chain stitches are continuous. At this time, by adjusting at least one of the cycle at which the stretch yarn 20 is inserted into the chain stitches, the thickness, and each yarn feed amount according to the target elongation of the lace, it is possible to appropriately adjust the kickback (the force that returns to the original state from a stretched state).

[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 course direction in which a plurality of chain stitches are continuous. Specifically, as illustrated in FIG. 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 so that they all follow the same insertion path. At this time, by adjusting at least one of the cycle at which the elastic composite yarn 25 is inserted into the chain stitches and the amount of each yarn sent, according to the target elongation of the lace, the gap H1 between the core yarn 250 and the covering yarn 252 illustrated in FIG. 3(A), i.e., the protruding amount of the pile formed by the covering yarn 252, can be appropriately adjusted.

[0029] In step 104 (S104), the worker causes the front jacquard machine to form the pattern portion 6 illustrated in Fig. 1. Specifically, the front jacquard machine inserts pattern yarns into the chain stitches of the formed basic structure 12, and forms a floral pattern with the jacquard yarns 30 at a position that will become the back side of the knitted lace 1.

[0030] In step 106 (S106), the operator causes the front jacquard machine to form the ground knit structure 2 illustrated in Fig. 1. Specifically, as illustrated in Fig. 2, the front jacquard machine inserts the jacquard yarn 30 led from the jacquard reed into the chain stitches of the basic structure 12, and connects two adjacent basic structures 12, among the multiple basic structures 12 arranged in the wale direction, to each other at a position that will become the front side of the knitted lace using the stretch yarn 20 and the stretchable composite yarn 25 to form the ground knit structure 2. The front jacquard machine connects the wales of the two adjacent basic structures 12 using the jacquard yarn 30, and forms the openwork portion 4 and ground pattern 5 illustrated in Fig. 1. In this manner, in the above steps S100, S102, S103, S104, and S106, knitting and the like are performed on the same course by the knitting operation of the front jacquard knitting machine, and a knitted lace before dyeing processing is manufactured. Note that in this example, knitting is performed by a front jacquard machine, but this is not limited to this, and it is sufficient that the stretch yarn 20 and the stretchable composite yarn 25 are positioned on the back side of the knitted lace 1 relative to the jacquard yarn 30 and the pattern yarn, and it can also be realized by a so-called back jacquard machine in which the insertion positions of S104 and S106 are interchanged.

[0031] In step 108 (S108), the worker dyes at least one of the pattern portion 6 and the ground knit structure 2 of the knitted lace (piece dyeing). The dye is selected, for example, by selecting an acid dye when dyeing nylon yarn, selecting a reactive dye or a direct dye when dyeing cotton, rayon, and cupra, and selecting a cationic dye when dyeing cationic dyeable polyester, and then performing the desired color scheme. There are also cases where the color of scouring, etc. is not added. In this way, by this manufacturing method, it is possible to manufacture a knitted lace in which the stretch yarn 20 and the stretchable composite yarn 25 are arranged on the back side of the knitted lace 1 in the thickness direction of the knitted lace. Note that, although the case of piece dyeing has been described in this manufacturing method, it is also possible to use yarn dyeing or knitting with dope-dyed yarn. The worker also performs a heat treatment (heat setting step) in which the core yarn 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 stretch yarn 20. In the heat setting step, the elastic composite yarn 25 and the stretch yarn 20 are bonded together while adjusting the desired pitch and width, thereby obtaining the knitted lace 1 shown in Fig. 1. The heat setting conditions at this time are a temperature of 160°C to 200°C for 90 seconds or less, and preferably a temperature of 180°C to 190°C for 40 seconds to 80 seconds.

[0032] As explained above, according to the knitted lace 1 of this embodiment, the stretch yarn 20 that imparts stretchability to the chain stitches of the basic structure 10, and the elastic composite yarn 25 that imparts pile are inserted according to their roles, so that the lace elongation and the amount of pile protrusion can be appropriately adjusted, resulting in a lace that feels better against the skin. Also, by inserting the stretch yarn 20 and the elastic composite yarn 25 along the same insertion path so that they run parallel to each other, the transparency of the knitted lace 1 is not impaired. In addition, since the elastic composite yarn 25 is disposed on the back surface of the knitted lace 1, the functional effect of the functional fiber used in the covering yarn 252 is more pronounced during use. Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications and additions can be made without departing from the spirit and scope of the invention.

[0033] Next, a modification of the above embodiment will be described. In the modified example, elements having substantially the same functions and configurations as those in the above embodiment are designated by the same reference numerals and redundant description will be omitted. [Variation 1] In the above embodiment, the chain stitch yarn 10 forming the basic weave 12 is a single material yarn of nylon, and the stretch yarn 20 is a polyurethane elastic yarn, but this is not limiting, and the chain stitch yarn 10 may be a composite yarn of heat-fusible polyurethane and nylon, and the stretch yarn 20 may be a heat-fusible polyurethane elastic yarn. In this way, by using heat-fusible yarns for the chain stitch yarn 10 and the stretch yarn 20, it is possible to prevent span loss and fraying. [Explanation of symbols]
