In general, warp knitted fabrics used for clothing and the like are required to have various designs. However, all of the above-mentioned free-cut warp knitted fabrics of the prior art are so-called plain fabrics, that is, plain fabrics, and are not mesh-like stretchable warp knitted fabrics. Therefore, there has been a demand for a free-cut warp knitted fabric that can reduce seams such as sewing, has excellent elasticity and breathability, and can express a design such as a mesh pattern. ..
Further, conventionally, there has been no elastic warp knitted fabric having a non-slip feature.

The present invention has been made in view of the above circumstances, and an object of the present invention is that it is not necessary to clean up the edges in the state of being cut, and the present invention has excellent elasticity, breathability and design. It is an object of the present invention to provide a stretchable warp knitted fabric having excellent properties and clothing using the same.

Another object of the present invention is to provide an elastic warp knitted fabric which does not require edge cleaning after cutting and has a non-slip effect, and a garment using the same.

Stretchable warp knitted fabric of the present invention is a stretchable warp knitted fabric is knitted by a non-stretchable knitting yarns and elastic yarns, the elastic yarns, the mesh tissue by insertion of a plurality of types are organized, the line contact portion in which at least two said elastic yarn to accompany to pass between the same needle from between the same needle as it is knitted one course is formed between all of course, the line contact The elastic threads of the portion are joined to each other by heat fusion .

Further, the garment of the present invention is a garment using the above-mentioned elastic warp knitted fabric according to the present invention, and is characterized by having an edge portion that has not been trimmed in the state of being cut.

According to elastic warp knitted fabric of the present invention, is organized by the inextensible yarn and elastic yarn, the elastic yarn is knitted into a mesh structure by the insertion of a plurality of types. As a result, the stretchable warp knitted fabric exhibits excellent stretchability in the vertical, horizontal, and diagonal directions, and also has excellent breathability.

In addition, a line contact portion accompanied by at least two types of the elastic threads is formed between all courses . As a result, the inserted elastic threads overlap at the line contact portion, making it difficult to pull out. Therefore, it is possible to suppress fraying of the edge portion formed when the elastic warp knitted fabric is cut.

In this way, since the fraying of the edge portion formed by cutting is suppressed, it is not necessary to perform finishing such as sewing processing to prevent the fraying of the edge portion, and the processing to clothing or the like can be easily performed. be able to. That is, the elastic warp knitted fabric can be used as a free-cut warp knitted fabric.

The stretchable warp knitted fabric of the present invention has a plurality of types of stretchable threads , and the stretchable threads are inserted in an overlapping manner. As a result, the elastic warp knitted fabric is knitted in a mesh shape. Therefore, the breathability and design of the stretchable warp knitted fabric are improved, and a stretchable warp knitted fabric having excellent elasticity, breathability and designability can be obtained by free cutting.

Further, according to the present invention, the elastic threads at the line contact portion may be joined to each other by heat fusion. As a result, the effect of suppressing fraying of the cut edge can be enhanced.
Further, since the elastic yarn between the line contact portion is fixed by welding, the yarn of the stretchable yarns omission can be suppressed. As a result, the tension of the knitting yarn and the elastic yarn when knitting the elastic warp knitted fabric can be suppressed to a low level. As a result, the range of knitting condition settings is widened, and the elasticity and power of the elastic warp knitted fabric can be freely adjusted.

Further, since the yarn pulling out of the elastic yarn is suppressed by the fusion of the line contact portion, for example, a yarn made of polyester fiber or the like which is easily pulled out as a knitting yarn, a yarn thinner than the warp knitted fabric of the prior art, etc. , Threads of various thicknesses and materials can be used depending on the application. This enables a variety of design expressions of elastic warp knitted fabrics suitable for each application.

Further, according to the present invention, a point contact portion where at least two types of the elastic threads intersect may be formed. As a result, the elastic threads are fused to each other at the point contact portion, so that the effect of suppressing fraying of the edge portion can be obtained.

Further, by forming the point contact portion, the stretchable thread protrudes to one main surface of the stretchable warp knitted fabric. Therefore, the one main surface on which the elastic thread of the elastic warp knitted fabric protrudes becomes hard to slip. That is, a free-cut elastic warp knitted fabric having a non-slip function can be obtained.
Further, the stretchable warp knitted fabric is knitted into a dot pattern or the like by projecting the stretchable yarn onto one main surface of the stretchable warp knitted fabric. As a result, a design effect can be obtained.

Further, according to the present invention, at least two types of the elastic threads may be inserted in the same knitting structure while being shifted in the course direction. As a result, at least two types of elastic threads are overlapped to form a point contact portion. Therefore, the dot pattern or the like can be knitted by the formed point contact portion, and the effect of suppressing fraying can be further enhanced.

Further, by knitting at least two types of elastic threads with the same knitting structure, the lengths of the two types of threads used when knitting the elastic warp knitted fabric are substantially the same. Therefore, the same yarn supplied from the same beam can be used as the two types of elastic yarns knitted with the same knitting structure. That is, two types of elastic threads can be inserted by the threads supplied from one beam. As a result, it is possible to knit more types of knitting yarns and elastic yarns than the number of beams that can be mounted on the knitting machine, which is efficient.

Further, according to the present invention, the stretchable thread may be inserted by being swung in the same wale direction for each course. As a result, it is possible to form many line contact portions and point contact portions where the elastic threads come into contact with each other and overlap each other. Therefore, since the portion where the stretchable threads are joined by heat fusion increases, the range where fraying occurs when cut can be reduced, and the stretchable warp can be reduced regardless of the cutting direction and shape. Fraying from the edge of the knitted fabric can be suppressed.

Further, according to the present invention, the stretchable yarn may contain polyurethane fibers. As a result, heat can be applied to the stretchable warp knitted fabric to easily fuse the stretchable threads together. Further, since the polyurethane fiber has excellent elasticity, the elasticity of the elastic warp knitted fabric can be further increased.

Further, according to the present invention, there may be a hem formed by removing the thread removal after inserting and knitting the thread removal. As a result, the hem of the stretchable warp knitted fabric does not need to be cut with scissors or the like when it is processed into clothing or the like. Therefore, it can be easily processed into clothing or the like. In addition, by knitting the hem, the kinks of the edges of the elastic warp knitted fabric are reduced, and the edges are neatly arranged. Therefore, sewing finishing processing and the like can be reduced. In addition, since it is possible to reduce folds and seams at the edges of clothing, it is possible to improve the feel when worn and improve the design.

Further, according to the garment of the present invention, the garment using the above-mentioned elastic warp knitted fabric may have an edge portion that has not been trimmed in the state of being cut. As a result, the labor of sewing can be saved, and the productivity of clothing can be increased. Further, since the cut edge portion is not sewn or the like, the number of seams in the vicinity of the edge portion can be reduced, the design can be improved, and the feel when worn can be improved.

Hereinafter, the stretchable warp knitted fabric according to the embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded view of the knitted structure of the stretchable warp knitted fabric 1 according to the embodiment of the present invention. It should be noted that FIGS. 1 to 5 show how the knitting yarn and the elastic yarn are knitted when they are knitted from the lower side to the upper side. Further, in FIGS. 1 to 5, the point H indicates a place where the needle passes when knitting the warp knitted fabric.

In the following description, the course direction is the direction in which the elastic warp knitted fabric 1 is woven, and is the vertical direction in FIGS. 1 to 5. Further, the wale direction is the swing direction of the reed, which is the left-right direction in FIGS. 1 to 5.

The elastic warp knitted fabric 1 is a mesh-shaped warp knitted fabric, and is used for, for example, underwear such as soft girdles, sports products such as gloves, and medical products such as supporters. As shown in FIG. 1, the elastic warp knitted fabric 1 is knitted by one kind of knitting yarn and three kinds of elastic yarn . Specifically, stretchable warp knitted fabric 1 includes a knitting yarn 11, the yarn 12 as yarn first stretch, a yarn 13 as yarn of the second elastic, the third stretchable It has a thread 14 as a thread .

The knitting yarn 11 is a non-stretchable yarn, and as the knitting yarn 11, for example, a yarn made of synthetic fibers such as polyester and nylon, natural fibers such as cotton and silk, and the like is used. The thickness of the knitting yarn 11 is preferably, for example, 22 dtex (decitex) to 78 dtex.

The knitting yarn 11 is knitted by a power knitting structure 21 in which the needle train Y1 to the needle train Y6 are repeated units. Specifically, the knitting structure 21 is the same knitting structure as one of the pair of knitting threads knitted in the power knitting of 6 courses. That is, the knitting structure 21 knitted by the knitting yarn 11 forms a loop that becomes an opening or a closing every time one course is knitted.

Specifically, the knitting yarn 11 passes through the inter-needle A3 and forms an opening with respect to the needle between the inter-needle A2 and the inter-needle A3 (needle row Y1), and then the knitting yarn 11 passes through the needle. It passes through the space A2 and forms a closure with respect to the needle between the needles A2 and the needles A3 (needle row Y2). Next, the knitting yarn 11 passes through the inter-needle A2 and forms a closed stitch with respect to the needle between the inter-needle A1 and the inter-needle A2 (needle row Y3).

Next, the knitting yarn 11 passes through the inter-needle A2 and forms an opening with respect to the needle between the inter-needle A2 and the inter-needle A3 (needle row Y4). Next, the knitting yarn 11 passes through the inter-needle A3 and forms a closed stitch with respect to the needle between the inter-needle A2 and the inter-needle A3 (needle row Y5). Next, the knitting yarn 11 passes through the inter-needle A3 and forms a closed stitch with respect to the needle between the inter-needle A3 and the inter-needle A4 (needle row Y6).
The knitting yarn 11 used for the elastic warp knitted fabric 1 may be knitted by another knitting structure.

The thread 12 is an elastic thread. As the thread 12, a thread containing polyurethane fibers is preferable, and for example, spandex, which is a polyurethane fiber, is used. The thickness of the thread 12 is appropriately selected according to the intended use, and is preferably 33 dtex to 620 dtex, for example.

The thread 12 is inserted by a 12-course knitting structure 22 having the needle train Y1 to the needle train Y12 as a repeating unit. The knitting structure 22 is a knitting structure in which no loop is formed, and is a substantially meandering knitting structure in which one to two stitches are alternately shaken in the wale direction for each course.

Specifically, the thread 12 passes between the needles B3 (needle row Y1) and passes through the needles B4 (needle row Y2). Next, the thread 12 passes between the needles B2 (needle row Y3) and passes through the needles B3 (needle row Y4). Next, the thread 12 passes between the needles B1 (needle row Y5) and passes through the needles B2 (needle row Y6). Next, the thread 12 passes between the needles B1 (needle row Y7) and passes through the needles B3 (needle row Y8). Next, the thread 12 passes between the needles B2 (needle row Y9) and passes through the needles B4 (needle row Y10). Next, the thread 12 passes between the needles B3 (needle row Y11) and passes through the needles B5 (needle row Y12).

As the thread 13, the same elastic thread as the thread 12 is used. That is, the thread 13 is, for example, a thread made of spandex or the like which is a polyurethane fiber, and the thickness of the thread 13 is preferably 33 dtex to 620 dtex.

Yarn 13 is knitted by the yarn 12 and the same knit structure 22 is inserted is offset 6 Course content in the course direction relative to the thread 12. That is, the thread 12 and the thread 13 have a common knitting structure 22, and differ only in the position in the course direction in which they are inserted.

Specifically, the thread 13 passes between the needles C1 (needle row Y1) and passes through the needles C3 (needle row Y2). Next, the thread 13 passes through the inter-needle C2 (needle row Y3) and passes through the inter-needle C4 (needle row Y4). Next, the thread 13 passes through the inter-needle C3 (needle row Y5) and passes through the inter-needle C5 (needle row Y6). Next, the thread 13 passes between the needles C3 (needle row Y7) and passes through the needles C4 (needle row Y8). Next, the thread 13 passes between the needles C2 (needle row Y9) and passes through the needles C3 (needle row Y10). Next, the thread 13 passes between the needles C1 (needle row Y11) and passes through the needles C2 (needle row Y12). In this way, the yarn 13 is knitted by a 12-course knitting structure 22 inserted from the needle train Y1 with the needle train Y12 as a repeating unit.

As described above, since the thread 12 and the thread 13 are inserted by the same knitting structure 22, the lengths of the thread 12 and the thread 13 used in the elastic warp knitted fabric 1 are substantially the same. Specifically, in one repeating unit, that is, the needle train Y1 to the needle train Y12, the lengths of the thread 12 and the thread 13 used are substantially the same.

As a result, when the elastic warp knitted fabric 1 is knitted, the same yarn supplied from the same beam can be used as the yarn 12 and the yarn 13. In other words, two types of elastic threads, namely thread 12 and thread 13, can be inserted by the same thread supplied from one beam.

With such a configuration, when knitting the elastic warp knitted fabric 1, it is possible to knit more kinds of knitting yarns and elastic yarns than the number of beams that can be attached to the knitting machine. As a result, increasing the overlap of such yarn 12 and yarn 13 of stretchable warp knitted fabric 1, it is possible to increase the free cutting property.

Further, by using many kinds of elastic threads such as the thread 12 and the thread 13, various design expressions can be performed and the design can be enhanced. Further, even with a knitting machine having a small number of available beams, it is possible to knit the stretchable warp knitted fabric 1 having excellent free-cutting property and designability.

In the above example, as the thread 12 and the thread 13, the same being supplied from the same beam but yarn was used, as the yarn 12 and the yarn 13, for example, different types of supplied from different beam Threads may be used.

The thread 14 is an elastic thread. As the thread 14, a thread containing polyurethane fibers is preferable, and for example, spandex, which is a polyurethane fiber, is used. The thickness of the thread 14 is appropriately selected according to the intended use, and is preferably 78 dtex to 620 dtex, and may be different from the thread 12 and the thread 13.

The yarn 14 is inserted by a 6-course satin knitting structure 24 having the needle train Y1 to the needle train Y6 as a repeating unit. Specifically, the thread 14 passes between the needles D2 (needle row Y1) and passes through the needles D3 (needle row Y2). Next, the thread 14 passes through the inter-needle D1 (needle row Y3) and passes through the inter-needle D3 (needle row Y4). Next, the thread 14 passes through the inter-needle D2 (needle row Y5) and passes through the inter-needle D4 (needle row Y6).

Further, the elastic warp knitted fabric 1 has a hem 41 and a thread 15 for knitting the hem 42 shown in FIG. As the thread 15, for example, a synthetic fiber such as polyester is used. The yarn 15 is knitted by a chain knitting structure 25 having the needle train Y1 to the needle train Y2 as a repeating unit.

Specifically, the thread 15 passes through the inter-needle E1 and forms an opening with respect to the needle between the inter-needle E1 and the inter-needle E2 (needle row Y1). Next, the thread 15 passes through the inter-needle E2 and forms an opening with respect to the needle between the inter-needle E1 and the inter-needle E2 (needle row Y2).

FIG. 2 is an organizational chart showing a part of the elastic warp knitted fabric 1. As shown in FIG. 2, the stretchable warp knitted fabric 1 is knitted by knitting yarn 11, thread 12, thread 13 and thread 14.
The knitting yarn 11 is inserted as a full set. That is, the knitting yarn 11 that knits the knitting structure 21 is inserted into all the guides of the reed that knits the knitting yarn 11. In this way, the knitting yarn 11 is inserted between all the needles, and as described above, a loop that becomes an opening or a closing is formed for each needle.

The thread 12 is inserted in a so-called 2in2out. Specifically, the thread 12 is continuously inserted between two needles in the wale direction, and is continuously inserted between the next two needles with a space between two needles next to the thread 12. .. That is, the thread 12 is inserted into the guide the yarn 12 are arranged in two successive reed being inserted, without being inserted into two guides of the lateral, is set by repeating this.

Further, the thread 13 is inserted 2in2out like the thread 12. Specifically, the thread 13 is continuously inserted between two needles like the thread 12, and is continuously inserted between the next two needles with a space between two needles next to the thread 13. Will be done. That is, the yarn 13 is inserted into the guide the yarn 13 are arranged in two successive reed being inserted, without being inserted into two guides of the lateral, is set by repeating this.

Further, the thread 12 and the thread 13 are inserted in a substantially meandering shape by being shaken alternately in the wale direction, that is, alternately left and right, each time one course is advanced. Here, in the needle train Y1 to the needle train Y6, the thread 12 is inserted by swinging one stitch when it is swung to the left in the wale direction and by swinging two stitches when it is swung to the right.

In this way, since the thread 12 is inserted from the needle row Y1 to the needle row Y6 by being swung more to the right than to the left, it is inserted diagonally from the left side to the right side in the wale direction. .. That is, the thread 12 is inserted from the needle row Y1 to the needle row Y6 in the diagonally right direction with respect to the course direction, that is, in the diagonally upward right direction in FIG.

Further, in the needle row Y6 to the needle row Y12, the thread 12 is shaken by two stitches when it is swung to the left in the wale direction, and by one stitch when it is swung to the right. In this way, since the thread 12 is inserted from the needle row Y6 to the needle row Y12 by being swung more to the left than to the right, it is inserted diagonally from the right side to the left side in the wale direction. .. That is, the thread 12 is inserted from the needle row Y6 to the needle row Y12 in the diagonally leftward direction with respect to the course direction, that is, in the diagonally upward leftward direction in FIG.

Further, the threads 13 inserted by the same knitting structure 22 are also inserted alternately in the oblique direction like the threads 12. Specifically, the thread 13 is inserted diagonally to the left with respect to the course direction from the needle row Y1 to the needle row Y6, and is inserted diagonally to the right with respect to the course direction from the needle row Y6 to the needle row Y12. To. As described above, since the yarn 12 and the yarn 13 by changing the swing width is inserted obliquely direction alternately, stretchable warp knitted fabric 1, the course direction, is excellent stretchability in the wale direction and the oblique direction It will be demonstrated.

Further, as described above, the thread 12 and the thread 13 each have the same knitting structure 22 that is largely swung in the wale direction, and are inserted with a deviation of 6 courses in the course direction, so that the thread 12 and the thread 13 overlap each other. A part is formed.

The thread 14 is inserted as a full set. That is, the thread 14 is inserted between all the needles in the wale direction. In other words, the thread 14 is inserted into all the guide reeds yarn 14 is inserted.

By inserting the three types of elastic threads, that is, the threads 12, the threads 13 and the threads 14 as described above, the threads 12, the threads 13 and the threads 14 are overlapped with each other to form a mesh structure, and the elastic warp knitting is performed. The ground 1 is knitted in a mesh shape. As a result, a large number of stitches are formed on the stretchable warp knitted fabric 1, so that the stretchable warp knitted fabric 1 is excellent in breathability. In addition, the stretchable warp knitted fabric 1 can exhibit various designs. In addition, another kind of knitting yarn or yarn may be added to the elastic warp knitted fabric 1. That is, the elastic warp knitted fabric 1 may be knitted by two or more types of knitting yarns, or may be knitted by inserting three or more types of elastic yarns.

Figure 3 is a tissue diagram extracting only the thread 12, the thread 13 and the thread 14 of the elastic warp knitted fabric 1 shown in FIG. In addition, in FIG. 3 and FIG. 4, the F portion indicated by the ellipse of the alternate long and short dash line indicates the vicinity of the portion where the line contact portion 31 described later is formed.

As shown in FIG. 3, the thread 12, the thread 13, and the thread 14 are inserted so as to form a portion where they overlap each other. Specifically, the stretchable warp knitted fabric 1 is formed with a line contact portion 31 accompanied by two types of stretchable threads , which are the thread 12, the thread 13, and the thread 14. Here, the accompaniment means that when one course is woven, the same needles pass through the same needles and are inserted so as to overlap each other.

Specifically, in the needle train Y3 to the needle train Y9, the thread 13 and the thread 14 accompany each other in the F portion to form the line contact portion 31. Further, in the needle row Y9 to the needle row Y15, the thread 12 and the thread 14 accompany each other in the F portion to form the line contact portion 31. The knitting structure from the needle row Y13 to the needle row Y15 is the same as the knitting structure from the needle row Y1 to the needle row Y3. In this way, in the stretchable warp knitted fabric 1, one or more line contact portions 31 are always formed when any two of the thread 12, the thread 13 and the thread 14 accompany and knit for one course. To.

By forming the line contact portion 31, the thread 12, the thread 13 and the thread 14 are in an overlapping state at the line contact portion 31. Therefore, fraying when the stretchable warp knitted fabric 1 is cut can be suppressed. As a result, the stretchable warp knitted fabric 1 does not need to be sewn at the edge formed when it is cut, and the stretchable warp knitted fabric 1 can be easily processed into clothing or the like. Can be done.

The line contact portion 31 is formed by accompanying any two of the thread 12, the thread 13, and the thread 14, but the line contact portion 31 is not limited to this, and for example, another elastic thread is added to make 3 A line contact portion 31 may be formed by accompanying a stretchable thread of this or more. As a result, a plurality of elastic threads can be brought into contact with each other and overlapped with each other, and the effect of suppressing fraying at the time of cutting can be enhanced.

FIG. 4 is an enlarged organizational chart of the thread 12, the thread 13, and the thread 14 shown in FIG. Note that the G portion indicated by the broken line circle in FIG. 4 indicates the vicinity of the portion where the point contact portion 32 is formed. As shown in FIG. 4, the stretchable warp knitted fabric 1 is formed with a point contact portion 32 in which at least two types of stretchable threads of the thread 12, the thread 13, and the thread 14 overlap and intersect.

For example, in the G1 portion shown in FIG. 4, the thread 13 and the thread 14 are inserted between the same needles. When the thread 14 is inserted from the needle row Y1 toward the G1 portion, the thread 14 is inserted from between the needles on the left side in the wale direction with respect to the thread 13. Further, when the thread 14 is inserted from the G1 portion toward the needle row Y3 beyond the thread 14, the thread 14 is inserted between the needles on the right side in the wale direction with respect to the thread 13. As a result, in the G1 portion, the yarn 13 and the yarn 14 intersect to form the point contact portion 32.

Further, for example, in the G2 portion, the thread 12 and the thread 14 are inserted between the same needles. When the thread 14 is inserted from the needle row Y3 toward the G2 portion, the thread 14 is inserted from between the needles on the right side in the wale direction with respect to the thread 12. Further, when the thread 14 is inserted from the G2 portion toward the needle row Y5 beyond the thread 14, the thread 14 is inserted between the needles on the left side in the wale direction with respect to the thread 12. As a result, the thread 12 and the thread 14 intersect to form the point contact portion 32.

As described above, when the thread 12, the thread 13 and the thread 14 intersect with each other at the point contact portion 32, the intersected thread 12, the thread 13 and the thread 14 project to one main surface of the elastic warp knitted fabric 1. To do. By projecting the elastic threads 12, the thread 13 and the thread 14 to one main surface, the friction coefficient of one main surface of the elastic warp knitted fabric 1 becomes large, and the elastic warp knitted fabric 1 becomes One main surface becomes hard to slip. That is, the free-cut elastic warp knitted fabric 1 having a non-slip function can be obtained by the configuration in which the point contact portion 32 is formed.

As a result, the stretchable warp knitted fabric 1 can be used as a cloth used for clothing or the like that requires not only elasticity but also a non-slip function, such as sports products such as gloves and medical products such as supporters. Suitable. The stretchable warp knitted fabric 1 is not limited to the above-mentioned cloth products such as gloves and supporters, and can be used as a non-slip member for various products.

In addition, the point contact portion 32, which is formed in a regular arrangement and projects on one main surface of the stretchable warp knitted fabric 1, provides a visual effect. That is, the point contact portion 32 causes a pattern such as a dot pattern to appear on the stretchable warp knitted fabric 1, and the design of the stretchable warp knitted fabric 1 is enhanced.

Further, the thread 12, the thread 13 and the thread 14 do not protrude from the other main surface, which is the opposite side of one main surface. As a result, the other main surface is formed smoothly, so that it feels good to the touch when worn as clothing or the like.

Further, the stretchable warp knitted fabric 1 knitted as described above is subjected to a heat setting process, which is a step for maintaining the stability of its form and dimensions, after the knitting step. In the heat setting process, the stretchable warp knitted fabric 1 after being knitted is set in a shape under appropriate tension, and heat is applied to improve the stability of the stitches of the stretchable warp knitted fabric 1. be able to.

In particular, in the elastic warp knitted fabric 1 according to the present embodiment, the yarn 12, the yarn 13 and the yarn 14 are heat-sealed by the heat setting treatment. Specifically, in the line contact portion 31 and the point contact portion 32 shown in FIGS. 3 and 4, the thread 12, the thread 13 and the thread 14 are joined by fusion. The yarn 12, the yarn 13, and the yarn 14 include fibers having a melting point lower than that of the knitting yarn 11. As described above, since the thread 12, the thread 13 and the thread 14 are formed of threads containing polyurethane fibers, heat fusion between the threads 12, the threads 13 and the threads 14 can be easily performed.

Here, the heat setting treatment of the stretchable warp knitted fabric 1 is performed at a temperature higher than the temperature of the heat setting treatment applied to the knitted fabric as a pre-process such as general dyeing. Specifically, the heating temperature in the heat setting treatment is preferably 185 ° C to 210 ° C. When the heating temperature is lower than 185 ° C., the heat fusion of the thread 12, the thread 13 and the thread 14 in the line contact portion 31 and the point contact portion 32 becomes insufficient, and the effect of suppressing the fraying of the cut edge portion is small. .. On the other hand, if the heating temperature exceeds 210 ° C., the thread 12, the thread 13 and the thread 14 may melt and the shape may not be maintained.

As a more preferable condition, the heating temperature in the heat setting treatment is 190 ° C. to 200 ° C., more preferably 194 ° C. to 198 ° C.
By performing the heat setting treatment under such conditions, the bonding between the thread 12, the thread 13 and the thread 14 in the line contact portion 31 and the point contact portion 32 becomes good, and the thread 12 and the thread 13 are bonded to each other. And the thread 14 becomes difficult to separate. Therefore, the effect of suppressing fraying of the edge portion when cut is enhanced.

Thus, the thread 12 in line contact portion 31 and the point contact portion 32, by the thread 13 and the thread 14 are fixed to each other is fused, the yarn 12, the yarn of the yarn 13 and yarn 14 omission can be suppressed. As a result, the tension of the knitting yarn 11, the yarn 12, the yarn 13 and the yarn 14 when knitting the elastic warp knitted fabric 1 can be suppressed to a low level. As a result, the range of knitting condition settings is widened, and the elasticity, power, and the like of the elastic warp knitted fabric 1 can be freely adjusted.

Further, in the conventional general mesh-like warp knitted fabric, the stitches are knitted by non-stretchable threads. In a warp knitted fabric knitted with such non-stretchable threads, it has not been easy to make a warp knitted fabric that is free-cut while maintaining a mesh-like structure. In the present embodiment, as described above, the mesh-like stitches are knitted by the elastic threads 12, the threads 13, and the threads 14. As a result, the stretchable warp knitted fabric 1 has become a completely new warp knitted fabric that is mesh-like and free-cut.

Further, the fusion of the line contact portion 31 and the point contact portion 32 suppresses the thread coming off of the thread 12, the thread 13 and the thread 14. Therefore, for example, yarns of various thicknesses and materials can be used as the knitting yarns 11, such as yarns made of polyester fibers that are easily pulled out, yarns thinner than the warp knitted fabric of the prior art, and the like. As a result, the stretchable warp knitted fabric 1 having elasticity and power suitable for various uses is knitted, and various design expressions are possible.

Further, when the stretchable yarn is inserted into the mesh-shaped warp knitted fabric knitted by the general non-stretchable yarn and knitted, the elasticity and power of the warp knitted fabric cannot be easily adjusted. As described above, the stretchable warp knitted fabric 1 is free-cut and has more elasticity and power adjustment than the conventional mesh-shaped warp knitted fabric knitted with general non-stretchable threads. It's easy.

Further, as shown in FIG. 3, since the thread 12, the thread 13, and the thread 14 are inserted by being swung in the same wale direction for each course, the thread 12, the thread 13, and the thread 14 come into contact with each other and overlap each other. Many line contact portions 31 and point contact portions 32 (see FIG. 4) are formed. As a result, it is possible to reduce the range in which fraying occurs when the material is cut. Therefore, fraying from the edge of the elastic warp knitted fabric 1 can be suppressed regardless of the cutting direction and shape.

As described above, the stretchable warp knitted fabric 1 does not require sewing finishing to prevent fraying of the edges formed by cutting, so that the edges are in the as-cut state, that is, the edges are free-cut. No need to clean up. Therefore, for example, when the stretchable warp knitted fabric 1 is used as a part of clothing, it is possible to reduce the number of steps of sewing the cut edge portion. As a result, the productivity of clothing can be increased.

Further, since the stretchable warp knitted fabric 1 does not require sewing of the cut edge portion, for example, the number of seams formed by folding back or the like can be reduced. As a result, the design of clothing and the like is improved. In addition, since there are no seams on the edges, it is possible to improve the feel when wearing clothing or the like. Therefore, the elastic warp knitted fabric 1 is particularly suitable for clothing such as soft girdles and underwear in which the knitted fabric comes into direct contact with the skin.

The stretchable warp knitted fabric 1 may be knitted so that the line contact portion 31 and the point contact portion 32 are formed at positions different from the above example. That is, the thread 12, the thread 13, and the thread 14 may be inserted at positions shifted in the course direction or the wale direction with respect to the above example.

For example, stretchable warp knitted fabric 1, when the yarn 12 is inserted is offset in the wale direction, the line contact portion 31 and the point contact portion 32 is formed by the yarn 12 is similarly displaced position in the wale direction. Further, when the thread 14 is inserted by being shifted by an even number of courses in the course direction, the line contact portion 31 and the point contact portion 32 formed by the thread 14 are also formed at positions shifted by an even number of courses in the course direction. .. As a result, different mesh patterns are formed, and various design expressions are realized.

FIG. 5 is an organizational chart of the elastic warp knitted fabric 1 in the vicinity of the hem 41 and the hem 42. As shown in FIG. 5, the stretchable warp knitted fabric 1 has a hem 41 and a hem 42. A thread 15 is knitted on the heme 41 and the heme 42, whereby the vicinity of the heme 41 and the heme 42 is reinforced and the strength is increased.

Further, a thread removal 16 is knitted between the hem 41 and the hem 42, that is, on the right side of the hem 41 and on the left side of the hem 42. The yarn removal 16 is, for example, various yarns made of synthetic fibers such as polyester, natural fibers, etc., and is knitted by the same knitting structure 25 as the yarn 15. The thread removal 16 is knitted so as to overlap only the thread 14.

As described above, since the thread removal 16 is knitted with few overlapping threads, the thread removal 16 can be easily pulled out from the elastic warp knitted fabric 1. When the thread-pulling 16 is pulled out, the elastic warp knitted fabric 1 is divided into an elastic warp knitted fabric 1a having a hem 41 and an elastic warp knitted fabric 1b having a hem 42. That is, the hem 41 and the hem 42 are the edges of the elastic warp knitted fabric 1.

By providing the hem 41 and the hem 42 as described above, the elastic warp knitted fabric 1 does not require cutting with scissors or the like in the hem 41 and the hem 42 when processing into clothing or the like. Therefore, as the stretchable warp knitted fabric 1, it is possible to use an edge portion formed by cutting and which does not require edge cleaning, and an edge portion formed by hem 41 and hem 42 which do not require cutting. As a result, processing into clothing or the like can be easily performed. The thread 14 intersecting the thread removal 16 may be inserted by two elastic threads. As a result, the strength of the edge portion formed when the thread-pulling 16 is pulled out can be further increased.

Further, by knitting the hem 41 and the hem 42, the twist of the edge portion of the elastic warp knitted fabric 1 is reduced, and the edge portion is neatly arranged. Therefore, sewing finishing processing and the like can be reduced. In addition, since it is possible to reduce folds and seams at the edges of clothing, it is possible to improve the feel when worn and improve the design.

[Example 1]
Hereinafter, the present invention will be described in more detail with reference to examples. The present invention is not limited to the examples listed below.

First, an evaluation test on the elasticity of the elastic warp knitted fabric 1 and the result thereof will be described.
The elastic warp knitted fabric 1 was knitted by the knitting structure shown in FIG. Here, as the knitting yarn 11, a yarn formed of polyester fibers and having a thickness of 56 dtex was used. Further, as the thread 12 and the thread 13, a thread formed of polyurethane fiber and having a thickness of 78 dtex was used, and as the thread 14, a thread formed of polyurethane fiber and having a thickness of 156 dtex was used.
Then, the stretchable warp knitted fabric 1 after being knitted was subjected to a heat setting treatment under heating conditions of 196 ° C.

A test piece having a width of 25 mm and a grip interval of 100 mm was formed from the elastic warp knitted fabric 1 knitted as described above. Then, the elongation rate (elongation rate) was measured by a tensile tester based on the A method (strip method) of JIS L1096. In addition, the test piece was changed and measurement was performed 5 times in each of the vertical direction and the horizontal direction, and the average value of the measured values of 5 times was calculated as the elongation rate.

As a result of the above test, it was confirmed that the stretchable warp knitted fabric 1 had an elongation rate of 247% in the vertical direction and 189% in the horizontal direction under a load of 22.05N. This is a sufficient elongation rate as an elastic warp knitted fabric used for underwear, sports equipment, and the like.

Next, using the stretchable warp knitted fabric 1 knitted as described above, an evaluation test was conducted for fraying and curling of the fabric. The evaluation test and its result will be described.
Five test pieces obtained by cutting the elastic warp knitted fabric 1 into a 30 cm square and five test pieces cut into a circle having a diameter of 30 cm were prepared. For the test piece, a washing step of 10 minutes for washing, 10 minutes for the first rinse, 5 minutes for the second rinse and 20 minutes for dehydration was carried out 30 times, and a step of 80 minutes for tumble drying was carried out every 6 times of the washing step. It was carried out once in a total of 5 times.

After the washing step and the drying step were carried out, the test piece of the stretchable warp knitted fabric 1 was visually confirmed, and the presence or absence of fraying or curling of the edge was determined.
As a result, no fraying or curling was confirmed on the edge of the test piece. As a result, it was determined that the stretchable warp knitted fabric 1 is suitable as a free-cut fabric.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
