[0002] For example, Patent Document 1 discloses a method for manufacturing a Raschel lace fabric after performing a weaving process and a heat treatment process. The weaving process is to install a plurality of chain yarns forming each chain tissue extending along the weaving direction, a transverse crossover woven transversely between the plurality of chain tissues formed by the chain yarns, and a thermoplastic yarn with fusibility that is partially or completely melted after heat treatment on a Raschel warp knitting machine to weave a Raschel fabric. The heat treatment process is to heat treat the Raschel fabric obtained in the weaving process. In the weaving process, a fusible yarn portion composed of a fusible material that is partially or completely melted after heat treatment is used as the first chain portion, and a refractory yarn portion composed of a refractory material having a melting temperature higher than that of the fusible material is used as the second chain portion, and a plurality of chain tissues having both the first chain portion and the second chain portion in the same chain tissue are woven, and at the same time, an insertion yarn composed of the same material as the fusible material is inserted into the chain tissue to weave a Raschel fabric. In the heat treatment process, the Raschel fabric obtained in the weaving process is heat treated in a tense state to obtain a Raschel lace fabric. The heating temperature is not higher than the melting temperature of the difficult-to-melt material and the transverse crossover, and not lower than the melting temperature of the fusible material, and the execution time is the treatment time of the difficult-to-melt yarn portion and the transverse crossover remaining as yarn.

[0003] In addition, Patent Document 2 discloses a method for weaving using a multi-bar warp knitting machine, comprising step 1 of preparing a raw yarn, step 2 of feeding the raw yarn into a looping bar, and step 3 of causing the looping bar to start a weaving operation. The multi-bar warp knitting machine is characterized in that the raw yarn is composed of N (N≥1) yarns, and at least one of the N yarns is an anti-spinning yarn.

[0047] The following will describe embodiments of the present invention with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.

[0048] First, refer to Figure 1 to Figure 4 , explaining the composition of the pattern knitted lace 1.

[0049] Figure 1 This is an exemplary diagram of the patterned knitted lace 1 according to the present embodiment.

[0050] like Figure 1 As shown, the patterned knitted lace 1 (hereinafter referred to as knitted lace 1) is knitted lace that is at least partially used in knitted lace products. Knitted lace products are knitted lace products that at least partially contain knitted lace 1, such as underwear, outerwear or sportswear and other clothes, medical supplies such as bandages, corsets, braces such as correction belts or orthodontic belt rings, eye masks, sheet masks or facial masks and other skin care products, and indoor products such as curtains. In addition, the knitted lace products in this example are clothes. They are used to make clothes, such as all or part of women's underwear. In addition, women's underwear includes basic underwear, decorative underwear and close-fitting underwear.

[0051] The knitted lace 1 is a warp knitted raschel lace woven 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 combining the shapes and configurations of the through holes. The knitted lace 1 has a base fabric 2 and a pattern portion 6 woven into the base fabric 2.

[0052] The base fabric structure 2 is a fabric structure formed by connecting two adjacent basic structures (basic structures 12 described later). For example, the base fabric structure 2 includes a chain weave structure, a twill structure, an Atlas patterned silk structure, an elastic mesh structure, etc. In addition, the base fabric structure 2 in this example is a chain weave structure, which has the function of preventing yarn from slipping (preventing thread fraying) between adjacent basic structures 12 (in the longitudinal direction of the coils).

[0053] In addition, the base fabric structure 2 includes a through portion 4 and a base fabric pattern 5 .

[0054] The through portion 4 is a region where the number of yarns arranged per unit area is relatively sparse and is provided with various multi-mesh through holes.

[0055] The base fabric pattern 5 is a region where the amount of yarn arranged per unit area is relatively dense, and forms a predetermined pattern.

[0056] The pattern portion 6 is a region where the pattern yarn is woven into the base fabric structure 2 to decorate the base fabric structure 2. The pattern portion 6 expresses the outline, shade, or unevenness of a pattern (hereinafter also referred to as a pattern) by the thickness and density of the woven pattern yarn.

[0057] Figure 2 It is a diagrammatic example for explaining the knitting structure of the patterned knitted lace 1. In addition, for convenience of explanation, intervals are provided between the yarns, but in fact, the yarns are closely attached to each other.

[0058] like Figure 2 As shown, the knitted lace 1 has a chain yarn 10, a basic structure 12 formed by the chain yarn 10, a first coil 14, a second coil 15, an inserted yarn 20, an inserted yarn 40 (not shown), a jacquard yarn 50 (not shown) and a pattern yarn 60 (not shown).

[0059] The chain yarn 10 is a knitting yarn that forms a plurality of continuous chain loops of a basic structure 12 (described later). The chain loops formed by the chain yarn 10 include a loop stem 10A and a sinker loop 10B. The chain yarn 10 forms a basic structure 12 as a base of the base fabric structure 2 by continuously forming chain loops.

[0060] In addition, the chain yarn 10 is a yarn formed by synthetic fibers in chemical fibers, and is a single material yarn or a composite yarn. For example, when the chain yarn 10 is a single material yarn (such as filament yarn), it is formed by polyamide nylon (nylon), acrylic or polyester fiber, etc. In addition, when the chain yarn 10 is a composite yarn, for example, it is an elastic yarn that is bonded to other yarns by melting the material when heated, that is, a composite yarn with a thermoplastic elastic yarn as the core and a nylon yarn as the covering. In addition, the chain yarn 10 can also be a yarn containing functional fibers such as contact warmth, contact coldness, or antibacterial and deodorizing. For example, the warm-feeling functional fiber yarn can be an acrylic fiber yarn, and the cold-feeling functional fiber yarn can be a cuprammonia fiber yarn. It is also possible to appropriately select a combination of materials or composite materials according to other additional purposes or effects such as antibacterial and deodorizing. In addition, regarding the composite method of the composite yarn, known composite processing methods such as core-spun processing, air interlacing processing, and twisting processing can be appropriately selected. In addition, the plaiting yarn 10 in this example is a multifilament yarn formed of nylon.

[0061] The basic structure 12 is a continuous knitting structure of multiple chain loops formed by the chain yarn 10. The basic structure 12 is as shown in FIG. Figure 2 As shown, the basic structures 12A to 12D are included. In addition, for the convenience of explanation, the basic structures 12A to 12D are collectively referred to as the basic structures 12 when no special distinction is required. The basic structures 12 are arranged in parallel in a direction (hereinafter referred to as the coil column direction) orthogonal to the direction in which the multiple chain stitches are continuous (hereinafter referred to as the coil row direction). In addition, in the basic structures 12, the respective coils of two adjacent basic structures 12 are arranged at adjacent positions.

[0062] In addition, the basic tissue 12 has a yarn slip prevention section 100 that connects two adjacent basic tissues. The yarn slip prevention section 100 uses the chaining yarn 10 that forms the basic tissue 12 to move horizontally from the chaining loop of one of the two adjacent basic tissues 12 to the chaining loop of the other basic tissue 12, thereby connecting the two adjacent basic tissues 12. The yarn slip prevention section 100 is regularly arranged. Regarding the arrangement period of the yarn slip prevention section 100, in the horizontal row direction of the coils of the basic tissue 12, for example, it is a period of more than 3 horizontal rows, the first scheme is a period of more than 3 horizontal rows and less than 20 horizontal rows, the second scheme is a period of more than 3 horizontal rows and less than 9 horizontal rows, and the third scheme is a period of more than 3 horizontal rows and less than 7 horizontal rows. In addition, the yarn slip prevention section 100 in this example is a period of 3 horizontal rows, connecting two adjacent basic tissues 12. In addition, the yarn slip prevention section 100 is an example of a connecting section according to the present invention.

[0063] The first loop 14 is a loop including a loop stem 10A formed by the chain yarn 10 and a loop stem 20A formed by the insertion yarn 20 described later, among the plurality of chain loops of the basic structure 12. In this example, the first loop 14 is a loop stem 10A to which the chain yarn 10 is bonded after the loop stem 20A of the insertion yarn 20 is melted. In addition, the first loop 14 is a chain loop at a position where the yarn slip prevention portion 100 is arranged.

[0064] The second coil 15 is a coil of the loop stem 10A formed by the chaining yarn 10 among the multiple chaining coils of the basic structure 12. In other words, the second coil 15 is a coil that does not include the loop stem 20A and only includes the loop stem 10A. The second coil 15 in this example is to allow the inserted yarn 20 to be located inside the sinker loop formed by the chaining yarn 10 or outside the sinker loop. The second coil 15 in this example inserts the inserted yarn 20 through the sinker loop formed by the chaining yarn 10, and bonds the inserted inserted yarn 20 at the contact point with the sinker loop. In addition, the second coil 15 is a chaining coil at a position where the yarn running prevention portion 100 is not configured.

[0065] The inserted yarn 20 is an example of the inserted yarn of the present invention, and is a yarn inserted into a plurality of loops of the basic structure 12 in the direction in which the multiple chain loops are continuous. The inserted yarn 20 is inserted into each basic structure 12 in the direction of the loop rows ( Figure 2 12A to 12D in FIG. 12A to 12D in FIG. 12B). In addition, the inserted yarn 20 includes a loop 20A.

[0066] The loop stem 20A is a loop stem formed by inserting the yarn 20. The loop stem 20A is arranged on some of the multiple coils included in the basic structure 12. Specifically, the loop stem 20A is regularly arranged on some of the multiple coils included in the basic structure 12. For example, the period of arranging the loop stem 20A may be one coil or multiple coils. Specifically, the period of arranging the loop stem 20A may be every 2 or more but less than 10 coils or every 2 or more but less than 10 coils. In addition, the arrangement period of the loop stem 20A in this example is every 3 coils (including 1 first coil 14 and 2 second coils 15), specifically, 1 first coil 14 is arranged every 2 second coils 15. In addition, the loop stem 20A is arranged on the chaining coil containing the lateral anti-yarn portion 100. The loop stem 20A formed here may be an open coil or a closed coil, and in this example, it is a closed coil. In addition, the loop stem 20A is in contact with the loop stem 10A. Specifically, the ring stem 20A may be in contact with the ring stem 10A in a state where at least a portion of them are in close contact, or in a state where at least a portion of them are crossed or overlapped.

[0067] In addition, there are many types of inserted yarns 20, such as yarns that are mainly adhesive, yarns that are mainly non-adhesive, or yarns that are both adhesive and stretchable. For example, when the inserted yarn 20 is mainly an adhesive yarn, it is a thermoplastic yarn or a thermal bonding yarn. An adhesive yarn is a yarn formed of a material that can bond with other yarns, such as a thermoplastic yarn that melts and deforms when heated and bonds with other yarns, and a thermal bonding yarn that is embedded in the concave and convex of other yarns when heated and deforms and bonds.

[0068] In addition, when the inserted yarn 20 is mainly a yarn without adhesiveness, it can be a chemical fiber yarn, a natural fiber yarn, or a composite yarn containing at least one of these yarns. For example, the chemical fiber yarn includes a yarn formed by polyurethane elastic yarn (so-called spandex elastic fiber), nylon or polyester fiber, etc. (In addition, among polyurethane elastic yarns, polyurethane elastic yarns without thermoplasticity are sometimes also called polyurethane stretch yarns). Natural fiber yarns are yarns formed by cotton, silk, wool, etc. A composite yarn containing at least one of these yarns refers to a yarn containing at least one of polyurethane elastic yarns, chemical fiber yarns such as nylon or polyester fiber, and natural fiber yarns such as cotton, silk or wool. In addition, the inserted yarn 20 is preferably a yarn with relatively strong friction, such as a polyurethane elastic yarn or a composite yarn containing a polyurethane elastic yarn. Polyurethane elastic yarn is a yarn that has both anti-slip properties and stretchability, which can prevent the yarn from falling off and help improve the stretchability of the fabric.

[0069] In addition, when the inserted yarn 20 is a yarn having adhesiveness and stretchability, it is a yarn made of a material having both thermoplasticity and stretchability in a linear form, such as a thermoplastic polyurethane elastic yarn (a thermoplastic polyurethane elastic yarn is sometimes also referred to as a polyurethane adhesive yarn). In addition, the inserted yarn 20 may also be a composite yarn containing an elastic yarn that stretches along the length direction of the yarn, for example, a composite yarn in which an elastic core yarn is wrapped with a covering yarn.

[0070] In addition, the inserted yarn 20 in this example is a thermoplastic and elastic yarn, that is, a thermoplastic polyurethane elastic yarn, which is more elastic than the chain yarn 10. At least a part of the inserted yarn 20 in the hot melt state includes the continuous part of the yarn. The inserted yarn 20 may include only the continuous part of the yarn, or may include both the continuous part of the yarn and the broken part of the yarn. Most of the inserted yarn 20 in this example is the continuous part of the yarn.

[0071] The functional insertion yarn 40 is an insertion yarn with excellent functionality inserted into the twill loops of the basic structure 12 formed by the twill yarn 10. The functional insertion yarn 40 in this example is inserted into each basic structure 12 ( Figure 212A to 12D in the basic structure 12). The functional insertion yarn 40 includes at least one of the elastic yarn 41, the adhesive yarn 42 and the functional yarn 43. The functional insertion yarn 40 can insert all of the elastic yarn 41, the adhesive yarn 42 and the functional yarn 43 into the chain loops of the basic structure 12, or select two of the elastic yarn 41, the adhesive yarn 42 and the functional yarn 43 to insert, or select one of the elastic yarn 41, the adhesive yarn 42 and the functional yarn 43 to insert. The functional insertion yarn 40 in this example selects the elastic yarn 41 and the adhesive yarn 42 to insert into the chain loops of the basic structure 12.

[0072] The elastic yarn 41 is an example of the second inserted yarn of the present invention, and is an elastic yarn that stretches in the length direction of the yarn. For example, the elastic yarn 41 may be a polyurethane elastic yarn (so-called spandex elastic fiber), which is a polyurethane elastic yarn without thermoplasticity (in addition, polyurethane elastic yarn without thermoplasticity is sometimes also called polyurethane stretch yarn). The elastic yarn 41 in this example allows the basic structure 12 to stretch in the row direction of the stitches. As a result, the elastic yarn 40 can make the base fabric structure 2 stretchable, and the knitted lace 1 is made into a stretch lace.

[0073] The bonding yarn 42 is an example of the second inserted yarn involved in the present invention, and is a yarn made of a material having bonding properties, specifically, a material having thermoplasticity, in a linear shape. The bonding yarn 42 utilizes the melting of the material when heated to perform the function of bonding with other yarns. In addition, the bonding yarn 42 may also be a bonding yarn having both thermoplasticity and elasticity (expanding and contracting along the length direction of the yarn). The bonding yarn 42 in this example is a thermoplastic polyurethane elastic yarn. In addition, the bonding yarn 42 may also be a composite yarn including an elastic yarn that expands and contracts along the length direction of the yarn, such as a composite yarn in which an elastic core wire is wrapped with a covering yarn. At least a portion of the bonding yarn 42 in a hot melt state includes a continuous portion of the yarn. The bonding yarn 42 may include only a continuous portion of the yarn, or may include both a continuous portion of the yarn and a broken portion of the yarn. Most of the bonding yarn 42 in this example is a continuous portion of the yarn.

[0074] Functional yarn 43 is an example of the second inserted yarn of the present invention, and is a yarn mainly composed of functional fibers such as contact warm feeling, contact cold feeling, or antibacterial and deodorizing. Functional yarn 43 is a single material yarn or a composite yarn. For example, the warm-feeling functional fiber yarn can be an acrylic fiber yarn, and the cold-feeling functional fiber yarn can be a cuprammonium fiber yarn. Alternatively, a composite yarn composed of different materials can be appropriately selected according to other additional purposes or effects such as antibacterial and deodorizing.

[0075] The jacquard yarn 50 is an example of the third insertion yarn of the present invention, and is an insertion yarn that is inserted into the chain loop of the basic structure 12 formed by the chain yarn 10, connects two adjacent basic structures 12, and forms the base fabric structure 2 having a lace pattern. The jacquard yarn 50 is located between the insertion yarn 20 and the insertion yarn 40.

[0076] The jacquard yarn 50 is a single material yarn or a composite yarn, and this example is a single material yarn. For example, when the jacquard yarn 50 is a single material yarn, it is a synthetic fiber or a regenerated fiber. When the jacquard yarn 50 is a composite yarn, it is a composite yarn of natural fiber or regenerated fiber and synthetic fiber, or a composite yarn composed of synthetic fiber. The natural fiber mentioned here refers to cotton, linen, silk or wool, etc., and the regenerated fiber refers to rayon, cuprammonium fiber or rich fiber, etc. In addition, the synthetic fiber refers to acrylic, polyester fiber, nylon or polyurethane, etc.

[0077] In addition, the jacquard yarn 50 may also be a thermoplastic bonding yarn, for example, a composite yarn with a polyurethane bonding yarn or a polyurethane stretch yarn as the core and wrapped with a nylon yarn. Therefore, the base fabric structure 2 can be prevented from fraying or breaking. The composite method of the jacquard yarn can be appropriately selected, for example, a known composite method such as a core-spun process, an air interlacing process or a twisting process. The jacquard yarn 50 is a composite yarn manufactured by the above composite method that meets the conditions.

[0078] In addition, the jacquard yarn 50 may also be a yarn mainly composed of functional fibers such as contact warmth, contact coolness, or antibacterial and deodorizing properties. For example, the warmth-sensitive functional fiber yarn may be an acrylic fiber yarn, and the cool-sensitive functional fiber yarn may be a cuprammonia fiber yarn. Alternatively, a composite yarn composed of different materials may be appropriately selected according to other additional purposes or effects such as antibacterial and deodorizing properties.

[0079] The pattern yarn 60 is inserted into the chain loop of the basic structure 12 formed by the chain yarn 10, connects two adjacent basic structures 12, and forms a lace pattern or pattern. The pattern yarn 60 is located on the surface of the knitted lace 1 and forms a pattern portion 6 by forming a predetermined pattern. The pattern yarn 60 is woven into Figure 1 The pattern portion 6 is formed in the base fabric structure 2 shown. The outline, shade or concave-convex of the pattern pattern is presented in the base fabric structure 2 by the thickness of the pattern yarn woven in and the density per unit area.

[0080] Figure 3 The figure explains the knitting structure of the pattern knitted lace 1 in detail.

[0081] Figure 4 This is a cross-sectional view illustrating the knitting structure of the patterned knitted lace 1 in detail.

[0082] In addition, for the convenience of explanation, intervals are provided between the yarns, but in reality, the yarns are closely attached to each other.

[0083] like Figure 3 As shown, the inserted yarn 20 is inserted into the basic structure 12 in the row direction of the chain structure 12, and the loop stem 20A is regularly arranged on a part of the loops. Here, the loop of the basic structure 12 including the loop stem 20A formed by the inserted yarn 20 is called the first loop 14, and the loop not including the loop stem 20A is called the second loop 15.

[0084] The elastic yarn 41 and the binder yarn 42 are inserted into the basic tissue 12 in the course direction of the chain tissue 12. In addition, the jacquard yarn 50 or the pattern yarn 60 connects two adjacent basic tissues 12 in the column direction of the chain tissue 12.

[0085] The chain structure 12 is formed by arranging a plurality of groups of coils in the horizontal row direction, with three coils, namely, one first coil 14 and two second coils 15 as one group. The arrangement period of the first coil 14 is every two second coils 15. Therefore, the arrangement period of the loop stem 20A is every two coils. That is, the loop stem 20A is arranged in the chain coil of the chain structure 12 in the part of the coil where the first coil 14 and the second coil 15 are regularly arranged. In addition, in the first coil 14, the chain yarn 10 and the insertion yarn 20 are formed by overlapping the loop stem 10A of the chain yarn 10 and the loop stem 20A of the insertion yarn 20. Therefore, even if the insertion yarn 20 is a non-adhesive yarn, the tension difference between the chain yarn 10 and the insertion yarn 20 can play a tightening role, and the friction resistance generated thereby can be used to reduce the frayed yarn. In addition, when the insertion yarn 20 is an adhesive yarn, it will be bonded to other yarns by the insertion yarn 20, thereby further reducing the frayed yarn.

[0086] In addition, regarding the chain structure 12 in this example, the case where it is arranged with one first coil 14 as a period is described, but it is not limited to this, and it can also be arranged with two or more (multiple) continuous first coils 14 as a period. In addition, the inserted yarn 20 can also be a combination of one first coil 14 and a plurality of continuous first coils 14.

[0087] Figure 4 This is a cross-sectional view illustrating the knitting structure of the patterned knitted lace 1 in detail.

[0088] like Figure 4 As shown, the loops of the chain structure 12 are formed by the loop stem 10A located on the surface of the knitted lace 1 in the thickness direction of the knitted lace 1 and the sinker loop 10B located on the back of the knitted lace 1. The inserted yarn 20, the inserted yarn 40, the jacquard yarn 50 and the pattern yarn 60 are inserted into the loops of the chain yarn 10.

[0089] The insertion yarn 20 is closer to the surface of the knitted lace 1 than the jacquard yarn 50 and the pattern yarn 60, and the functional insertion yarn 40 is closer to the back of the knitted lace 1 than the jacquard yarn 50 and the pattern yarn 60. In addition, the jacquard yarn 50 and the pattern yarn 60 are located between the insertion yarn 20 and the insertion yarn 40.

[0090] In summary, the knitted lace 1 improves the sense of transparency and prevents the thread from fraying by regularly arranging the loop stems 20A on some of the loops. In addition, the exposure frequency of the loop stems 20A of the inserted yarn 20 located on the first loop 14 is suppressed on the surface of the knitted lace 1. Therefore, the extreme stickiness of rubber can be suppressed at the part of the knitted lace 1 that contacts the skin.

[0091] Next, refer to Figure 5 A method for producing the knitted lace 1 will be described.

[0092] Figure 5 It is a flowchart explaining the manufacturing method (S10) of the patterned knitted lace 1.

[0093] The knitted lace 1 of this embodiment is woven using a front jacquard raschel warp knitting machine (hereinafter referred to as the front jacquard machine). The manufacturing method of this example will be used below, using the above-mentioned front jacquard machine to weave lace fabric, dyeing the woven lace fabric, and heat-treating the dyed lace fabric to obtain the knitted lace 1. In addition, this example uses the front jacquard machine for weaving, but it is not limited to this, and a back jacquard machine or the like can also be used.

[0094] like Figure 5 As shown, in step 100 (S100), the operator uses a comb bar to introduce the chaining yarn 10 into the knitting needle to form a chaining coil for warp knitting, and then arranges the formed multiple chaining coils in a row direction to form multiple basic tissues 12. The formed multiple basic tissues 12 are arranged at equal intervals in the longitudinal direction of the coils. In addition, the chaining yarn 10 is moved transversely with a period of 3 coil rows, and a yarn-slipping prevention part 100 is added to connect two adjacent basic tissues 12.

[0095] In step 102 ( S102 ), the operator inserts the insertion yarn 20 into the tuck stitch of the basic structure 12 formed by the tuck yarn 10 along the course direction of the stitches on the front jacquard machine to form a loop stem 20A as the first stitch 14 .

[0096] In step 104 (S104), the operator forms a second loop 20A on the chain loop located at a regular position starting from the first loop 14 forming the loop 20A on the front jacquard machine. Figure 3As shown, the operator starts by arranging the first stitch 14 of the loop stem 20A, and arranges the first stitch 14 forming the loop stem 20B in the plaiting stitch at a position two second stitches 15 apart.

[0097] In step 104 (S104), the operator inserts the insertion yarn 40 into the chain stitch of the basic structure 12 along the row direction of the stitches on the front jacquard machine. Figure 2 and Figure 3 As shown, at least a part of the elastic yarn 41 and the adhesive yarn 42 are arranged in the same insertion path in the horizontal row direction of the same basic structure 12. The elastic yarn 41 and the adhesive yarn 42 in this example are arranged in exactly the same insertion path. Specifically, the arrangement of the elastic yarn 41 and the adhesive yarn 42 is that the chaining coil of the inserting party and the chaining coil of the insertion target are the same chaining coils, and the yarn paths from the chaining coil of the inserting party to the chaining coil of the insertion target are the same, and they are parallel to each other as a whole. In addition, the elastic yarn 41 and the adhesive yarn 42 can also be insertion paths that intersect each other.

[0098] In step 106 (S106), the operator inserts the jacquard yarn 50 and the pattern yarn 60 into the chain loop of the basic structure 12 along the horizontal direction of the coil on the front jacquard machine, thereby forming Figure 1 The transparent part 4, the base fabric pattern 5, and the pattern part 6 are shown. Among the multiple jacquard yarns 50 inserted into the basic structure 12, two adjacent jacquard yarns 50 can also be configured to have at least a portion symmetry, and at least a portion overlap or cross each other.

[0099] In summary, in the above steps S100 to S106, the lace fabric before dyeing is manufactured by weaving on the same row of stitches through the weaving operation of the front jacquard machine.

[0100] In step 108 (S108), the operator dyes the woven lace fabric. In addition, this example illustrates dyeing after weaving, but it is not limited to this, and dyeing before weaving can also be performed. If it is raw yarn, this process can be omitted.

[0101] In step 110 (S110), the operator heats the inserted yarn 20 and the adhesive yarn 42 of the lace fabric to a temperature at which they melt, and performs heat treatment (heat setting process). Regarding the heat setting conditions during the heat setting process, for example, heating is performed at a temperature of 160°C to 200°C for less than 90 seconds, and preferably heating is performed at a temperature of 180°C to 190°C for more than 40 seconds to less than 80 seconds. After the heat setting process, the inserted yarn 20 and the adhesive yarn 42 are melted. The melted inserted yarn 20 and the adhesive yarn 42 have both continuous yarn parts and broken yarn parts, and the melted parts are attached to the chain yarn 10, the jacquard yarn 50 and the pattern yarn 60. Therefore, in the first coil 14, the loop stem 20A of the inserted yarn 20 is bonded to the loop stem 10A of the chain yarn 10. In addition, in the second loop 15, the inserted yarn 20 is bonded to the chuck yarn 10 at the position where it is inserted through the sinker loop of the chuck yarn 10 and at the position where it contacts the sinker loop. Figure 1 Knitted lace 1 shown.

[0102] As described above, the knitted lace 1 of this embodiment can improve the breaking strength by regularly arranging the loop stems 20A by using the inserted yarn 20 inserted into the chain loop of the basic structure 12, and bonding the loop stems 10A of the chain yarn 10 and the loop stems 20A of the inserted yarn 20. In addition, even when the knitted lace 1 is cut, it is possible to suppress the fabric from fraying from the cut edge.

[0103] In addition, the knitted lace 1 regularly forms and arranges the loop stems 20A on the surface of the knitted lace 1, thereby suppressing the exposure frequency of the loop stems 20A of the inserted yarn 20. Therefore, in the portion where the knitted lace 1 contacts the skin, the extreme stickiness of rubber can be suppressed, and a knitted lace having both softness and lace strength can be woven.

[0104] In addition, the knitted lace 1 is formed by inserting the elastic yarn 41 and the adhesive yarn 42 into the basic structure 12 in the same row direction through the same insertion path, so the sense of transparency is not affected.

[0105] Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and additions may be made without departing from the spirit of the present invention.

[0106] [Performance Evaluation of Examples and Comparative Examples]

[0107] The breaking strength test and the washing resistance test were carried out to evaluate the performance of each knitted lace of the embodiment and the comparative example.

[0108] First, the configurations of Examples and Comparative Examples will be described.

[0109] The knitted lace of this embodiment (hereinafter referred to as the embodiment) and the knitted lace of the comparative example (hereinafter referred to as the comparative example) are knitted laces woven using the same front jacquard machine and having the same pattern. The details of each knitted lace are described below.

[0110] The embodiment is formed by using a chain yarn as a 44dtx nylon yarn, starting from the surface of the knitted lace, sequentially inserting a 44dtx thermoplastic polyurethane elastic yarn A, a 44dtx jacquard yarn, a pattern yarn of 78dtx or more and 156dtx or less, a 78dtx polyurethane elastic yarn, and a 44dtx thermoplastic polyurethane elastic yarn B on a basic structure with a plurality of chain loops. The thermoplastic polyurethane elastic yarn A located on the surface of the knitted lace forms a loop stem every two loops in the plurality of chain loops included in the basic structure. The polyurethane elastic yarn and the thermoplastic polyurethane elastic yarn B located on the back of the knitted lace are all inserted through the same insertion path in the horizontal row direction of the loops of the same basic structure. Then, heat treatment is performed to fuse the thermoplastic polyurethane elastic yarn to other yarns. In this way, the knitted lace of the embodiment is obtained.

[0111] The comparative example is formed by inserting 44dtx jacquard yarn, pattern yarn of 78dtx or more and 156dtx or less, and 156dtx thermoplastic polyurethane elastic yarn into the basic structure of a plurality of continuous chain loops in sequence using the chain yarn of 44dtx nylon yarn from the surface of the knitted lace. Then, heat treatment is performed to fuse the thermoplastic polyurethane elastic yarn to other yarns. In this way, the knitted lace of the comparative example is obtained. There is no yarn equivalent to the thermoplastic polyurethane elastic yarn A located on the surface of the knitted lace in the embodiment in the comparative example, so there is no loop stem formed by the thermoplastic polyurethane elastic yarn A.

[0112] Next, the test methods and test results of the breaking strength test and the washing resistance test are described.

[0113] [Breaking strength test]

[0114] Figure 6 This is an example table of test results for measuring the breaking strength of patterned knitted lace.

[0115] (Purpose of the test)

[0116] The breaking strength of each knitted lace of the embodiment and the comparative example was compared and evaluated.

[0117] (Test method)

[0118] The test method is to use a Mullen-type breaking strength tester (simulation type) produced by Daiei Kagaku Seiki Manufacturing Co., Ltd., select a prescribed pattern at a mutually corresponding position in each knitted lace of the embodiment and the comparative example, and measure the breaking strength at 7 mutually corresponding positions for the selected pattern. In addition, the measured value is the value after the pressure counter value after measurement minus the value after the rubber film pressure is pressed.

[0119] (Test results)

[0120] like Figure 6 As shown, in the embodiment, the measured values ​​within the range of 223 kPa to 290 kPa are displayed, and the average value is 250 kPa. In the comparative example, the measured values ​​within the range of 207 kPa to 257 kPa are displayed, and the average value is 234 kPa. It can be confirmed that the average value of the breaking strength of the embodiment is increased by 16 kPa compared with the comparative example. In addition, in the part with the weakest breaking strength, the measured values ​​of 6 positions of the embodiment are 223 kPa, while the measured values ​​of 6 positions of the comparative example are 207 kPa, which can also confirm that the breaking strength is improved.

[0121] [Washing resistance test]

[0122] (Purpose of the test)

[0123] The frayed state of the cut edge portions of the knitted laces of the examples and comparative examples was compared and evaluated.

[0124] (Test method)

[0125] The test method is to use a household double-layer washing machine (model VH30S) produced by Toshiba Co., Ltd., perform a knitted lace washing program for 15 minutes × 20 times (continuous 300 minutes) and a drying program in which the washed knitted lace is hung to dry, and visually confirm the frayed state of the cut edge of each knitted lace of the embodiment and the comparative example. In addition, the washability test is implemented by a public testing agency.

[0126] (Test results)

[0127] Visual inspection confirmed that in the examples, the cut edges did not fray, while in the comparative examples, the cut edges frayed. It can be seen that the loops formed by the thermoplastic polyurethane elastic yarn on the surface of the knitted lace can suppress fraying.

[0128] Next, a modification example of the above-described embodiment will be described.

[0129] In the modified example, elements having substantially the same function and configuration as those of the above-described embodiment are denoted by the same reference numerals, and repeated description is omitted.

[0130] [Deformation Example 1]

[0131] In the above-mentioned embodiment of the patterned knitted lace 1, the chaining yarn 10 forms the anti-yarn-slipping portion 100, but the present invention is not limited thereto. In the patterned knitted lace 1 of this example, the chaining yarn 10 and the inserted yarn 20 form the anti-yarn-slipping portion. The inserted yarn 20 forms the loop stem 20A and the anti-yarn-slipping portion 200.

[0132] Figure 7 This is an illustrative diagram of a first modification of the patterned knitted lace 1 of the present embodiment. Figure 7 (A) and Figure 7 (B) is an example diagram of the contact arrangement of the yarn-missing prevention unit 100 and the yarn-missing prevention unit 200. Figure 7 (C) is an example diagram of the yarn-slip prevention unit 100 and the yarn-slip prevention unit 200 being separately arranged. Figure 7 (D) is an exemplary diagram showing that the yarn-interference prevention unit 100 and the yarn-interference prevention unit 200 are in contact with each other and the three basic tissues 12 are transversely shifted.

[0133] like Figure 7 As shown, the inserted yarn 20 in the knitted lace 1 of this example can also be inserted into all the basic tissues 12 along the longitudinal direction of the coils, or can be inserted into the basic tissues 12 at regular intervals such as 1 row interval. In this example, the intervals between the basic tissues 12 into which the inserted yarn 20 is inserted are enlarged, resulting in an increased possibility of stripes or holes in the knitted lace. From this perspective, the inserted yarn 20 is inserted into all the basic tissues 12.

[0134] The inserted yarn 20 has at least a yarn slip prevention portion 200 that connects two adjacent basic tissues 12. The yarn slip prevention portion 200 connects a plurality of continuous basic tissues 12 in the longitudinal direction of the stitches by using the inserted yarn 20 inserted into the basic tissue 12. The yarn slip prevention portion 200 is an example of the second connecting portion according to the present invention, and is arranged on the basic tissue 12 at regular periodic intervals or arbitrary intervals. Specifically, regarding the arrangement period of the yarn slip prevention portion 200, in the longitudinal direction of the stitches of the basic tissue 12, for example, a period of more than 3 courses, a first scheme is a period of more than 3 courses and less than 20 courses, a second scheme is a period of more than 3 courses and less than 9 courses, a third scheme is a period of more than 3 courses and less than 7 courses, and a fourth scheme is a period of more than 3 courses and less than 5 courses. In addition, the yarn slip prevention portion 200 in this example has the same period as the yarn slip prevention portion 100, and is arranged at a period of 3 courses to connect two adjacent basic tissues 12.

[0135] [Deformation Example 2]

[0136] In the patterned knitted lace 1 of the above-mentioned embodiment, the fabric is mainly stretched in the longitudinal direction (the horizontal row direction of the coils), but it is not limited to this. It can also be a fabric that stretches in the longitudinal direction (the horizontal row direction of the coils) and the transverse direction (the vertical row direction of the coils) like the patterned knitted lace 1 of this example.

[0137] Figure 8 This is an exemplary diagram of a second modification example of the patterned knitted lace 1 according to the present embodiment. Figure 8 (A) is an example diagram showing the insertion path of a single jacquard yarn 50. Figure 8 (B) is a diagram showing an example of the insertion path of the plurality of jacquard yarns 50.

[0138] In the patterned knitted lace 1 of this example, in addition to the structure described in the embodiment, the jacquard yarn 50 forming the base fabric structure 2 is also allowed to move horizontally along the longitudinal direction of the coils. Figure 8 As shown, the jacquard yarn 50 includes a plurality of connecting portions 500 .

[0139] like Figure 8 As shown in (A), the connecting portion 500 is an example of the third connecting portion of the present invention, and the jacquard yarn 50 is continuously inserted into three or more consecutive loops in the longitudinal direction of the loops in which a plurality of basic structures 12 are arranged, and the basic structures 12 including the inserted loops are connected. The connecting portion 500 in this example includes a connecting portion 500A and a connecting portion 500B.

[0140] The connecting portion 500A continuously inserts the jacquard yarn 50 into four consecutive stitches in the stitch row direction, and connects the basic structure 12 including the four stitches into which the jacquard yarn 50 is inserted. The connecting portion 500A inserts the jacquard yarn 50 into four stitches in each stitch course.

[0141] The connecting portion 500B continuously inserts the jacquard yarn 50 into three consecutive stitches in the stitch row direction, and connects the basic structure 12 including the three stitches into which the jacquard yarn 50 is inserted. The connecting portion 500B inserts the jacquard yarn 50 into three stitches in each stitch course.

[0142] In addition, the connecting portion 500 is not limited to the connecting portion 500A and the connecting portion 500B, and the jacquard yarn 50 may be inserted into five or more stitches that are continuous in the stitch row direction in each stitch course.

[0143] In addition, if Figure 8 As shown in (B), in the knitted lace 1, one jacquard yarn 50 is inserted into one basic structure 12. The jacquard yarn 50 inserted into each basic structure 12 adopts the same insertion path. Among them, a plurality of connecting parts 500 are inserted into the collective part 502 of the same loop of the basic structure 12.

[0144] The collection section 502 is an example of the collection section according to the present invention, and includes a collection section 502A and a collection section 502B.

[0145] The collective portion 502A is a portion where a plurality of connecting portions 500A are inserted into the same stitch of the basic structure 12. The collective portion 502A in this example has three jacquard yarns 50 on each stitch.

[0146] The collective portion 502B is a portion where a plurality of connecting portions 500B are inserted into the same stitch of the basic structure 12. The collective portion 502B in this example has two jacquard yarns 50 on each stitch.

[0147] The collection parts 502 are regularly arranged in the course direction of the continuous basic structure 12 stitches. In this example, the collection parts 502A and the collection parts 502B are arranged alternately in the course direction with three courses as a cycle.

[0148] In summary, the knitted lace 1 of this example connects more than three basic structures 12 with jacquard yarns 50, and at the same time, the collection part 502 where multiple connection parts 500 are located is regularly arranged in the horizontal row direction of the coils, so the breaking strength can be improved.
