Description

  The present invention relates to a method for producing a warp knitted fabric and a warp knitted fabric.

  In general, warp knitted fabrics are widely used as reinforcement and design accents, etc., used for a part of clothes and accessories. Since there are various irregularities and curves in the body, there is an increasing demand for warp knitted fabrics having a predetermined curve.

  Patent Document 1 relates to a collar core, in which a polyester fiber is used for at least one of the warp and weft yarns, and the other core is used to form a collar core, and a convex portion is formed in one direction with respect to the former fiber. There is a description that forming a curved surface and heat-treating at 140 ° C. or more stabilizes the shape in which the collar core is curved outward in the lateral direction (paragraph 0032).

  Patent Literature 2 relates to a fastener tape, and describes that a curve (S-shaped curve) is formed by attaching elastic members to left and right tapes at positions shifted from each other. As the background art, it is described that a tape continuously woven or knitted linearly is cut into a predetermined length and then deformed into a curved form. In general, weaving a tape so as to bend with a predetermined curvature is that a plurality of warp yarns running in a straight line parallel to the weaving direction has poor stretchability, and adjusts the yarn tension applied in the weaving direction. Alone, the tape cannot be bent horizontally with respect to the tape surface. Even if stretchable warps are used, not only the tension control is complicated, but also the maintenance becomes complicated and efficient. There is a description that it is difficult to produce well (paragraph 0003).

  Patent Document 3 relates to a piping tape, which is made of a woven fabric and is woven using a stretchable yarn as a warp, and has a stretchability in a longitudinal direction. In a natural state in which no tension is applied to the warp. There is a description that it is a piping tape to which a bend of a predetermined curvature resulting from a substantial decrease or increase in the warp yarn length direction in the tape width direction is provided (claim 1), and the manufacturing method thereof is a tape During weaving or knitting, weaving or knitting in a state where the tension applied to the warp is continuously or stepwise reduced or increased from one to the other in the width direction of the tape, the elongation strength as one warp (one warp) The tension required to stretch the tape by a unit elongation rate) is measured using a plurality of warp yarns that decrease or increase continuously or stepwise, generally stepwise, from one to the other in the tape width direction. A method of weaving or knitting the tape, a method of weaving the tape by decreasing or increasing the warp density (the number of warp yarns in the tape unit width) from one to the other in the width direction of the tape continuously or stepwise, tape A method of adopting a structure in which the number of warp yarn entanglement points (units of weft with wefts in a fabric) gradually decreases or increases from one side to the other side in the width direction of the tape, and There is a description that it can be produced by a combination of these methods (paragraph 0012).

  However, the method described in Patent Document 1 performs heat treatment on the fabric, and it is necessary to sufficiently consider the damage to the fabric due to heat, and the material of the yarn constituting the fabric is limited. Even if heat treatment is performed, it is difficult to form a curve with a large curvature. In addition, the fastener tape described in Patent Document 2 is configured to form a curve by combining a stretchable member with a tape fabric, so that a convex portion is formed, and the appearance is not good. There is a problem that the feeling of wearing is bad and the characteristics of the thin fabric are not utilized. The piping tape described in Patent Document 3 is composed of a woven fabric, and has a configuration in which a curve is formed by substantially decreasing (or increasing) the warp yarn length in the tape width direction. In the first place, the piping tape is a cored tape. Therefore, it is considered that the core material is presupposed, and it is considered that a thin fabric is not assumed. And these patent documents 1-3 do not describe forming a predetermined curve depending on how to knit the warp knitted fabric, and a method of forming a curve in consideration of the characteristics of the warp knitted fabric that expands and contracts in the longitudinal direction. Is different. That is, conventionally, it has not been possible to form a curve with a large curvature in a warp knitted fabric.

  Accordingly, an object of the present invention is to provide a method for producing a warp knitted fabric capable of forming a curve with a large curvature while taking advantage of the characteristics of the warp knitted fabric, and a warp knitted fabric having a good appearance. It is in.

  The method for producing a warp knitted fabric of the present invention comprises forming a belt-like warp knitting structure by knitting a stretchable insertion yarn in the warp direction and making a weft yarn in the course direction while making a stitch with a warp. A predetermined curve is formed by gradually increasing the tension applied to the insertion yarns from the insertion yarns on the outer line of the warp knitting structure to the insertion yarns on the inner line.

  According to the present invention, a stretched insertion yarn is knitted in the warp direction while making a stitch with a warp yarn, and a weft yarn is knitted in the course direction to form a belt-like warp knitted structure. By setting the tension applied to these insertion yarns in a stepwise manner from the insertion yarn of the outer line (outer peripheral line) to the inner line (inner peripheral line) of the warp knitting structure, a predetermined curve can be obtained. It can be formed with high reproducibility and can cope with a curve with a large curvature by setting the tension applied to these insertion yarns.

  In the present invention, the tension applied to the insertion thread of the inner peripheral line can be set to be twice or more the tension applied to the insertion thread of the outer peripheral line, and it becomes easy to form a curve with a large curvature.

  In the present invention, the tension applied to the insertion thread is gradually increased from the outer line toward the inner line to form the curve, and then to form a reverse curve opposite to the curve. The tension applied to the insertion thread is gradually increased from the inner line toward the outer line.

  According to the present invention, a reverse curve opposite to the curve can be continuously formed without sewing.

  The present invention is characterized in that the inner line is set in the middle of the belt-shaped warp knitting structure to form a slit.

  According to the present invention, the slit can be integrally formed in the middle of the warp knitting structure while knitting the warp knitted fabric.

The warp knitted fabric of the present invention has a warp knitting structure formed of a warp knitted in the warp direction, a stretch insertion thread knitted in the warp direction, and a weft knitted in the course direction. The tension applied to these insertion yarns is gradually increased as the insertion yarns on the outer line of the tissue are changed to the insertion yarns on the inner line, whereby one of the warp knitting structures is set as the outer line and the other of the warp knitting structures is set as the inner line. The characteristic curve is continuous for more than half a circle.
The warp knitted fabric of the present invention has a warp knitting structure formed of a warp knitted in the warp direction, a stretch insertion thread knitted in the warp direction, and a weft knitted in the course direction. A curve having one side of the structure as the outer line and the other side of the warp knitting structure as the inner line is continuous for more than half a circle, and the inner line is set in the middle of the warp knitting structure in the band shape, and a slit is formed. It is characterized by that.
The warp knitted fabric of the present invention has a warp knitting structure formed of a warp knitted in the warp direction, a stretch insertion thread knitted in the warp direction, and a weft knitted in the course direction. The tension applied to these insertion yarns is gradually increased as the insertion yarns on the outer line of the tissue are changed to the insertion yarns on the inner line, whereby one of the warp knitting structures is set as the outer line and the other of the warp knitting structures is set as the inner line. The curve is continuous for more than half a circle, and then the reverse curve opposite to the curve is formed by gradually increasing the tension applied to the insertion thread from the inner line toward the outer line. It is characterized by.

  According to the present invention, the band-shaped warp knitting structure is formed by the warp formed with the stitches, the stretchable insertion yarn knitted in the warp direction, and the weft knitted in the course direction. Since it becomes a uniform warp knitted fabric and the seamless curve is continuously formed for more than half a circle, it has a good appearance and a feeling of wearing.

According to the present invention, the position in which the insertion yarn is knitted into the stitch and the position in which the weft is knitted into the stitch are in a one- to -one correspondence, so that the expansion and contraction in the longitudinal direction of the tape is uniform. Become. And if it is set as the structure which knits the said insertion yarn and the weft for every said stitch, it will become a warp knitted fabric with a high stretch property which is hard to fray.

  As the stretchable insertion thread, a stretchable thread made of polyurethane, latex, elastomer, natural rubber or the like, a composite thread of these, a twisted thread, or the like is applied. A non-stretchable yarn is applied to the warp and the weft, but the stretchable yarn may be applied. Non-stretchable yarns include non-stretchable yarns made of rayon, polyester, nylon, acrylic, natural fibers, etc., composite yarns of these, and twisted yarns.

  In general, the material of the warp is different from the material of the insertion thread, but the material of the warp may be the same as that of the insertion thread. By making the material of the warp yarn the same material as the insertion yarn, the difference in stretch between the warp yarn and the insertion yarn is small, and uniform stretchability is exhibited in the length direction of the warp knitted fabric. In addition, if the weft yarn is made of the same material as the insertion yarn, the stretchability of the warp knitted fabric can be further increased, and a warp knitted fabric with high stretchability can be obtained.

  In the present invention, the thickness of the warp is set stepwise from the inner peripheral line toward the outer peripheral line, and the thickness of the warp in the outer peripheral line is the thickness of the warp in the inner peripheral line. In this configuration, the same thing as a combination of a plurality of warp knitted fabrics having different thicknesses can be obtained without sewing.

  The present invention is characterized in that the curve is formed from the outer line toward the inner line, and a reverse curve opposite to the curve is continuously formed.

  According to the present invention, the same thing as a combination of a plurality of fabrics having the curve can be obtained without sewing.

  The present invention is characterized in that the inner line is formed in the middle of the warp knitted structure having the belt shape to form a slit.

  According to the present invention, the slit is integrally formed in the middle of the warp knitting structure, and since the slit is non-sewn, it is difficult to fray and can be uniformly stretched, looks good, and feels comfortable to wear. This is preferable.

  According to the method for producing a warp knitted fabric of the present invention, a stretch-like insertion yarn is knitted in the warp direction while making a stitch with a warp, and a weft yarn is knitted in the course direction to form a belt-like warp knitted structure. The tension applied to these insertion yarns is increased stepwise as the insertion yarns from the outer line (outer peripheral line) to the inner line (inner peripheral line) of the warp knitting structure that becomes a belt-like pattern are changed. Thus, a predetermined curve can be formed with high reproducibility, and a curve with a large curvature can be dealt with by setting the tension applied to these insertion yarns. And it becomes easy to form a curve with a large curvature by setting the tension applied to the insertion thread of the inner peripheral line to be not less than twice the tension applied to the insertion thread of the outer peripheral line. Further, the S-shaped curve can be continuously produced without sewing. Then, the slit can be integrally formed in the middle of the warp knitting structure while knitting the warp knitted fabric.

According to the warp knitted fabric of the present invention, a belt-like warp knitted structure is formed by the warp formed with stitches, the stretchable insertion yarn knitted in the warp direction, and the weft knitted in the course direction. Therefore, a thin and uniform warp knitted fabric is formed, and a seamless curve is continuously formed for more than half a circle, so that the appearance is good and the wearing feeling is preferable. According to the present invention, the position where the insertion yarn is knitted into the stitch and the position where the weft is knitted into the stitch is in a one- to -one correspondence, so that the expansion and contraction of the tape in the longitudinal direction is uniform. It becomes a warp knitted fabric that is hard to fray and has high stretchability. And, the fabric in which the reverse curve opposite to the curve is continuously formed, and the fabric in which the inner line is formed in the middle of the warp knitting structure having the belt shape and is a slit, are not sewn. Since it is integrally formed, it is difficult to fray, and uniform expansion and contraction can be obtained.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a front view showing a warp knitted fabric to which the present invention is applied. The warp knitted fabric 1 of the present embodiment is a strip-shaped tape fabric, and exhibits high stretchability in the longitudinal direction and non-stretchability in the width direction. A curve having one of the warp knitting structures as an inner peripheral line (reference numeral 1a) and the other of the warp knitting structures as an outer peripheral line (reference numeral 1b) is continuously formed over a half circumference. Here, reference numeral 1c is a knitting start point, and reference numeral 1d is a knitting end point.

  FIG. 3 is a structural diagram showing a knitting structure of the warp knitted fabric 1 of the present embodiment. Reference numeral 2 (21, 22, 23) is a warp formed with stitches, reference numeral 3 (31, 32, 33) is a stretchable insertion thread knitted in the warp direction, and reference numeral 4 is knitted in the course direction. These wefts form a band-shaped warp knitted structure. Here, the warp 2 and the weft 4 are non-stretchable yarns, and are made of, for example, rayon, polyester, nylon, acrylic, natural fiber, or the like. The insertion thread 3 is a stretchable thread, and more specifically is made of polyurethane, latex, elastomer, natural rubber, or the like.

  The warp yarn 2 is chain-knitted, and the insertion yarn 3 is knitted in the warp direction in the shape of S in the stitch, and the weft yarn 4 is knitted in the course direction (FIG. 3). Here, there is a one-to-one correspondence between the position where the insertion yarn 3 is knitted into the stitch and the position where the weft yarn 4 is knitted, and the insertion yarn 3 and the weft yarn 4 are knitted for each stitch. Thereby, the expansion and contraction in the longitudinal direction of the tape fabric 1 is uniform, and the warp knitted fabric 1 having a high stretch property that is not easily frayed.

  The warp knitted fabric 1 of this embodiment is manufactured by a known Russell knitting machine, tricot knitting machine, or the like. In the present embodiment, the tension applied to the insertion yarns 33, 32, and 31 from the insertion yarn 33 of the outer line (outer peripheral line) 1b of the warp knitted structure having a belt shape to the insertion yarn 31 of the inner line (inner peripheral line) 1a Is set in a stepwise manner so that a predetermined curve is formed with high reproducibility, and even for a curve with a large curvature, it is a manufacturing method corresponding to the setting of the tension applied to these insertion yarns 33, 32, 31. (See FIG. 3). In FIG. 3, for the convenience of explanation, three warp yarns 2 (and three insertion yarns 3) are shown. However, two or more warp yarns 2 (and insertion yarns 3) may be used. The tape width of the warp knitted fabric 1 is increased (widened) as the number of warp yarns 2 (and insertion yarns 3) is increased.

  Here, for example, according to the method of setting the tension applied to the insertion thread 21 of the inner peripheral line 1a to be twice or more the tension applied to the insertion thread 23 of the outer peripheral line 1b, it is easier to form a curve with a large curvature. It becomes.

  FIG. 4 is another example of a structural diagram showing the knitting structure of the warp knitted fabric 1 of the present embodiment. Reference numeral 2 (21, 22, 23, 24, 25, 26) is a warp formed with stitches, and reference numeral 3 (31, 32, 33, 34, 35, 36) is an elastic insertion knitted in the warp direction. Reference numeral 4 (41, 42, 43, 44, 45) is a weft knitted in the course direction, and a band-shaped warp knitted structure is formed by these yarns. Here, the warp 2 and the weft 4 are non-stretchable yarns, and are made of, for example, rayon, polyester, nylon, acrylic, natural fiber, or the like. The insertion thread 3 is a stretchable thread, and more specifically is made of polyurethane, latex, elastomer, natural rubber, or the like. And the thickness (diameter) of the warps 21, 22, 23 is set to a value smaller than the thickness (diameter) of the warps 24, 25, 26, and the thickness (diameter) of the insertion yarns 31, 32, 33 is set. The thickness (diameter) of the insertion yarns 34, 35, 36 is set to a value smaller than the thickness (diameter) of the weft yarns 41, 42, and the thickness (diameter) of the weft yarns 43, 44, 45 is smaller than the thickness (diameter). (FIG. 4). According to this structure, the same thing as what combined several warp knitted fabrics from which thickness differs can be obtained without sewing.

  In the example shown in FIG. 4, the tension applied to the insertion yarns 36, 35, 34, 33, 32, 31 as the insertion yarn 36 of the outer peripheral line 1 b of the warp knitting structure having a band shape changes to the insertion yarn 31 of the inner peripheral line 1 a. By setting a strong step by step, a predetermined curve can be formed with high reproducibility, and a curve with a large curvature can be handled by setting the tension applied to these insertion threads 36, 35, 34, 33, 32, 31. In addition, a curve with a large curvature can be formed by setting the tension applied to the insertion thread 31 of the inner peripheral line 1a to more than twice the tension applied to the insertion thread 36 of the outer peripheral line 1b. Is even easier.

  FIG. 2 is another example of a front view showing a warp knitted fabric to which the present invention is applied. The warp knitted fabric 1 of the present embodiment exhibits high stretchability in the tape longitudinal direction and non-stretchability in the tape width direction. Then, the tension applied to the insertion yarn 3 is gradually increased from the first line 11b toward the second line 11a to form a curve, and then the second line 11a is changed to the first line 11b. A reverse curve opposite to the curve is formed by setting the tension applied to the insertion thread 3 stronger stepwise. According to this method, the S-shaped curve can be continuously produced without sewing.

  FIG. 6 is a perspective view showing a wearing state of a cap 100 of a white coat to which a known warp knitted fabric 101 is applied. With known techniques, a warp knitted fabric could not be used to form a curve with a large curvature. Therefore, the tape fabric 101 continuously knitted linearly was cut into a predetermined length and then deformed into a curved shape. The respective end portions are sewn on the sewing line 102. For this reason, the sewing line 102 is conspicuous, which is not preferable in appearance. In addition, the fabrics swell in the vicinity of the seam of the sewing line 102 and become swollen, and the overall unevenness makes the contact of the tape fabric 101 with the face unstable and uncomfortable (there is a feeling of chilliness) ), It was not comfortable.

  FIG. 5 is a perspective view showing a wearing state of a cap 10 of a lab coat to which the warp knitted fabric 1 according to the first embodiment of the present invention is applied. Since the warp knitted fabric 1 of the present embodiment is formed of a thin and uniform warp knitted fabric and a seamless curve is continuously formed over a half circumference, there is no such thing as the sewing line 102 depending on the manufacturing method. Good looking. Further, since there is no sewing line 102, a smooth curved surface is formed without swelled due to the seam or overall unevenness, and the contact of the tape fabric 1 with the face is stabilized. And fits well. In addition, sewing costs are reduced.

  A warp knitted fabric 1 according to an embodiment of the present invention includes various garments such as an inner portion of a hat, a supporter, and pants in addition to the above-described cap 10 of a white coat (cap for handling food or a work cap in a clean room). It is used as a part of jewelry and can be widely applied as reinforcement, stretchability, and design accents.

(Second Embodiment)
FIG. 7 is a structural diagram showing the knitting structure of the warp knitted fabric according to the second embodiment of the present invention. Here, the same code | symbol has shown the same function, and the description is partially abbreviate | omitted. The warp knitted fabric 1 of the present embodiment exhibits high stretchability in the longitudinal direction of the strip-shaped fabric, and exhibits non-stretchability in the width direction of the strip-shaped fabric. In FIG. 7, the knitting is performed from the bottom to the top, and the curved knitting structure is changed to a straight warp knitting structure. Here, the curve is formed such that one of the warp knitting structures is an inner line (reference numeral 1a) and the other of the warp knitting structures is an outer line (reference numeral 1b). Reference numeral 4 denotes a weft knitted in the course direction, and may have a configuration in which one weft is passed or a configuration in which a plurality of wefts are passed. In the example shown in FIG. 7, the inner line 1a has a narrower width at the turning point of the weft 4 knitted in the course direction, and the outer line 1b has a turning point of the weft 4 knitted in the course direction. The width at is wide and a natural curve is formed. In addition, the width | variety in the folding point of the weft 4 knitted in the said course direction by the inner side line 1a is made wide, and the width | variety in the folding point of the weft 4 knitted in the said course direction in the outer side line 1b is made narrow. Thus, a curve opposite to the curve is obtained.

  FIG. 8 is a structural diagram in which the knitting structures of the warp knitted fabric of the second embodiment are combined on the left and right. The warp yarn 2 is a chain knitting, and the insertion yarn 3 is knitted in the warp direction in an S shape on the stitch, and the two weft yarns 4 (41, 42) are knitted on the same course, In the example shown in FIG. 8, each course is branched into a left half course and a right half course, and the weft 41 is knitted into the left half course, and the weft 42 is knitted into the right half course. After being knitted in length, the weft 41 and the weft 42 are joined, and the two wefts 4 (41, 42) are knitted again on the same course. In the present embodiment, the inner lines 12a and 13a are formed in the middle of the warp knitting structure having a belt shape, and the two are connected to form an integral slit 6. In the example shown in FIG. 8, the knitting structure from the left outer line 12b to the inner line 12a and the knitting structure from the right outer line 13b to the inner line 13a are symmetrical. The branched left side knitting structure and right side knitting structure may have an asymmetric knitting structure, and the opening shape of the slit 6 may be set to an arbitrary shape.

  The warp knitted fabric 1 of this embodiment is manufactured by a known Russell knitting machine, tricot knitting machine, or the like. In the example shown in FIG. 8, the tension applied to the insertion yarns 31, 32, 33, 34 is increased stepwise as the insertion yarn 31 of the outer line 12 b of the warp knitted structure having a band shape changes to the insertion yarn 34 of the inner line 12 a. By setting, a predetermined curve is formed with high reproducibility, and even a curve with a large curvature is a manufacturing method corresponding to the setting of the tension applied to these insertion yarns 34, 33, 32, 31 (see FIG. 8). Similarly, the tension applied to the insertion yarns 38, 37, 36, and 35 is increased stepwise from the insertion yarn 38 of the outer line 13b to the insertion yarn 35 of the inner line 13a. Thus, a predetermined curve is formed with high reproducibility, and even for a curve with a large curvature, the manufacturing method corresponds to the setting of the tension applied to these insertion yarns 38, 37, 36, and 35. The number of lines in which the warp yarn 2 and the insertion yarn 3 are combined is symmetrical on the left and right sides of the slit 6 in the example shown in FIG. 8, but is not limited to this. Asymmetry with different widths may be used. Further, depending on the application, the stretch degree of the left knitting structure and the stretch degree of the right knitting structure can be made different.

  According to the present embodiment, the fabric in which the inner lines 12a and 13a are formed in the middle of the warp knitting structure 1 having the band shape and become the slit 6 is integrally formed without sewing. It is difficult to fray and a uniform expansion and contraction is obtained.

  FIG. 10 is a view showing a waist belt 200 to which known warp knitted fabrics 211 and 212 are applied. FIG. 10A is a front view, FIG. 10B is a plan view, and FIG. 10C is a rear view. With the known technology, it was not possible to form a curve around the warp knitted fabric, so the warp knitted fabrics 211 and 212 knitted continuously in a straight line were cut into a predetermined length and then curved Each of the inner sides is sewed with a sewing line 213, and the longitudinal ends of the formed slits 216 are sewn with a zigzag sewing line 214 so that the sewing lines 213 and 214 are conspicuous. It has become. Further, since the knitting structures of the seams of the sewing lines 213 and 214 are different, the degree of expansion and contraction is not uniform, and the attachment feeling is not good. Further, the stress was concentrated on the sewing lines 213 and 214, and it was easy to hurt. Here, reference numeral 108 denotes one side member of the hook and loop fastener, and reference numeral 109 denotes the other side member of the hook and loop fastener. Reference numeral 107 denotes a reinforcing tape that reinforces the outer periphery of the waist belt.

  FIG. 9 is a view showing a waist belt 20 to which the warp knitted fabric 11 according to the second embodiment of the present invention is applied. 9A is a front view, FIG. 9B is a plan view, and FIG. 9C is a rear view. By applying the warp knitted fabric 11 of the present embodiment, the fabric in which the inner lines 12a, 13a are formed in the middle of the warp knitted structure in the form of the belt and become slits 6 is integrally formed without sewing. Is formed. FIG. 11 is a perspective view showing a wearing state of the waist belt 20 to which the warp knitted fabric 11 of the second embodiment is applied. Fig.11 (a) is the figure seen from the front side, FIG.11 (b) is the figure seen from the diagonal back side. The waist belt 20 is formed of a band-shaped body having a wide central portion in the longitudinal direction, and the slit 6 is integrally formed in the longitudinal direction of the stretchable warp knitted fabric 11 that expands and contracts in the longitudinal direction. The surface fasteners 108 and 109 are sewn, and the outer periphery of the warp knitted fabric 11 is reinforced by the reinforcing tape 107. The waist belt 20 is attached to the back side of the body at the center in the longitudinal direction and fastened to the left and right of the front side of the body (FIG. 11 (a)). The band-like part lifts the buttocks of the body, and the upper band-like part tightens the waist of the body (FIG. 11 (b)). According to the present article, by adjusting the opening state of the slit 6, it is possible to adjust how the force is applied to the collar portion, that is, the lifted state and the location to be covered.

  According to the present embodiment, since the slit 6 is integrally formed without sewing, it is difficult to fray and a uniform expansion and contraction is obtained, and it has a good appearance and a good feeling of wearing. , Sewing cost is reduced. Moreover, according to a use, the expansion degree of the knitting structure by the side of a buttock shown in FIG.11 (b) and the expansion / contraction degree of the knitting structure by the back side can be varied. For example, it is possible to increase the elasticity of the knitted tissue on the buttock side to enhance the hip-up effect, and to reduce the elasticity of the knitted tissue on the back side to reduce the tightening feeling.

  The warp knitted fabric 11 according to the embodiment of the present invention is used for a part of various clothes and accessories such as supporters and pants in addition to the above-described waist belt 11 (medical waist belt and shape waist belt). It can be widely applied as reinforcement, stretching, and design accents.

From the insertion yarns on the outer line of the warp knitting structure By setting the tension applied to these insertion yarns stepwise as they become the insertion yarns on the inner line, a curve with one side of the warp knitting structure as the outer line and the other side of the warp knitting structure as the inner line continues for more than half a circle. Warp knitted fabric characterized by   A band-shaped warp knitting structure is formed by a warp formed with a stitch, a stretchable insertion thread knitted in the warp direction, and a weft knitted in the course direction, with one of the warp knitting structures as an outer line. A warp knitted fabric characterized in that a curve having the other side of the warp knitting structure as an inner line is continuous for more than half a circle, and the inner line is set in the middle of the warp knitting structure in the form of a band and a slit is formed . A band-shaped warp knitting structure is formed by the warp yarns that form the stitches, the stretchable insertion yarns knitted in the warp direction, and the weft yarns knitted in the course direction. From the insertion yarns on the outer line of the warp knitting structure By setting the tension applied to these insertion yarns stepwise as they become the insertion yarns on the inner line, a curve with one side of the warp knitting structure as the outer line and the other side of the warp knitting structure as the inner line continues for more than half a circle. Next, a reverse curve opposite to the curve is formed by gradually increasing the tension applied to the insertion thread from the inner line toward the outer line. Knitted fabric.
