Description

  The present invention relates to a weft knitted fabric, a method for knitting a weft knitted fabric, and apparel, and more particularly to a weft knitted fabric in which a front yarn and a back yarn having a higher elasticity than the front yarn are knitted by knitting.

  Various garments are manufactured using a horizontal knitted fabric knitted using a circular knitting machine or a horizontal knitting machine. For example, Patent Document 1 proposes a knitted fabric in which a solid part is formed by roughening the degree of the body cloth of the three-dimensional part and closing the degree of the cloth around the three-dimensional part.

  Patent Document 2 describes a garment in which a three-dimensional part is continuously knitted on a part of a body cloth part composed of a knitted fabric, the size of the stitch is larger than that of the body cloth part, and a yarn is added. A garment having a three-dimensional part that bulges from the body cloth part by being inserted is proposed.

  Such a garment is a molded garment manufactured mainly using a cylindrical knitted fabric knitted by a circular knitting machine, and a decorative yarn as a front yarn and an elastic yarn as a back yarn are knitted by knitting. It consists of knitted fabric. And various patterns come to be realized by knitting by changing the color of the decorative yarn as the front yarn.

  In Patent Document 3, regarding the knitted fabric in which the ground knitted portion by the front yarn and the back yarn and the patterned knitted portion by the pattern yarn and the back yarn are repeatedly knitted as appropriate, the stitches of the yarn switching portion are increased. In order to solve the appearance problem that the end of the yarn appears on the surface, a knitted fabric is proposed in which a bulky processed yarn for stitch adjustment is knitted as a supplementary yarn to one to several wales immediately before and / or after the patterned knitting structure. ing.

  FIG. 5 shows an example of a knitted fabric employing the configuration described in Patent Document 3. The knitted fabric includes a region A knitted by splicing knitting using a nylon-based mixed yarn of a predetermined color (for example, black) as a front yarn and a single covered yarn (SCY) as a back yarn, and a front yarn The front yarn is switched between the region B knitted by splicing using a nylon-based mixed yarn of different colors (for example, pink) and a single covered yarn (SCY) as the back yarn, and the yarn A bulky processed yarn is knitted as a supplementary yarn in the region C of the switching portion.

  The bulky processed yarn knitted as a splicing yarn makes it possible to prevent the stitches from becoming dense in the region C, that is, the boundary of yarn switching, and the yarn end of the front yarn to protrude to the front side of the knitted fabric.

  However, although the stitches are dense, the two colors of the front yarn are exposed and mixed in the boundary region C, and there is a problem that the aesthetic appearance is impaired.

  In view of the above-described problems, the object of the present invention is that the aesthetic appearance is not impaired even if the yarn end of the front yarn protrudes to the front side of the knitted fabric without causing deterioration of the aesthetic appearance due to color mixing at the yarn switching portion. It is in the point which provides the knitting method of a knitted fabric, a horizontal knitted fabric, and clothing.

  In order to achieve the above-mentioned object, the first characteristic configuration of the weft knitted fabric according to the present invention is as described in claim 1 of the claims, and the front yarn and the back yarn having a higher elasticity than the front yarn. Is a weft knitted fabric knitted by splicing knitting, comprising a yarn switching unit that switches the surface yarn knitted in the course direction to another surface yarn, and at least one course in units of a predetermined number of courses, At least two continuous stitches of the second and fifth stitches before and after the yarn switching portion are knitted, and the front and back are knitted.

  When welt knitting (floating knitting) at least two stitches across the yarn switching part, the tension of the back yarn, which is more stretchable than the front yarn, acts at that part, and the knitted fabric toward the yarn switching part Will be attracted. Since such a course is repeated in units of a predetermined number of courses, the stitches of the course knitted between the welt-knitted stitches protrude to the front side, and as a result, the wale direction across the yarn switching portion Two linear protrusions are formed. In such a state, even if the yarn end of the surface yarn that has been switched to the yarn may protrude to the surface side of the knitted fabric, it is covered with two linear protrusions, so that it can be visually observed in appearance. It does not stand out to the extent, and color mixing at the yarn switching section as described in the prior art does not occur. The knit knitting refers to an operation of forming one stitch by a single threading operation on the knitting needle, and the welt knitting refers to an operation of floating the yarn on the back of the knitted fabric without applying the yarn to the knitting needle. .

  In the second characteristic configuration, as described in claim 2, in addition to the first characteristic configuration described above, the yarn switching portion is continuously formed in a linear or curved shape in the wale direction. It is in.

  When the yarn is switched in a plurality of courses and the yarn switching portion is continuous in the wale direction, the yarn switching portion is not limited to a linear shape in the wale direction, and is a mode in which the yarn switching portion is continuously formed in a curved shape. 2 linear protrusions are formed in a straight line or a curved line across the thread switching part continuously formed in a straight line or a curved line, and each thread switching part Even if the yarn end protrudes to the front side, the yarn end is covered with two linear protrusions.

  The third characteristic configuration is that, as described in the third aspect, in addition to the first or second characteristic configuration described above, it is knitted in a cylindrical shape by a single circular knitting machine.

  A horizontal knitted fabric knitted in a cylindrical shape by a single circular knitting machine is very preferable in that a seamless garment that is comfortable to wear can be realized without using side stitches by utilizing the cylindrical shape.

  The knitting method of the horizontal knitted fabric according to the present invention is characterized in that, as described in claim 4, the knitted method of the horizontal knitted fabric in which the front yarn and the back yarn having higher elasticity than the front yarn are knitted by knitting. A yarn switching step of switching a front yarn knitted in the course direction to another front yarn at a predetermined yarn switching portion, before and after the yarn switching portion before and after the yarn switching step. The yarn end covering step further includes a yarn end covering step in which welt knitting is performed on at least two continuous stitches among the second to fifth stitches, and knit knitting is performed on the front and back.

  The tension of the back yarn, which is more stretchable than the front yarn, acts on the portion that is knitted in the yarn end coating step, and the knitted fabric is drawn toward the yarn switching portion. When such a course is repeated in units of a predetermined number of courses, the stitches of the course knitted between the welt-knitted stitches protrude to the front side, and two linear lines in the wale direction sandwiching the yarn switching part A convex part is formed. Even if the yarn end of the surface yarn that has been switched over may protrude to the surface side of the knitted fabric later, it is covered with two linear projections and is conspicuous enough to be visually visible There is no.

  The characteristic configuration of the garment according to the present invention is that it is formed of a horizontal knitted fabric having any one of the first to third characteristic configurations described above.

  According to the above-described configuration, even if the yarn end protrudes to the front side at the yarn switching portion of the knitted fabric, it is not noticeable, and clothing that does not impair the beauty can be provided.

  As described above, according to the present invention, a knitted fabric that does not impair the appearance even if the yarn end of the front yarn protrudes to the front side of the knitted fabric without causing a decrease in the aesthetic appearance due to color mixing at the yarn switching unit. The knitting method and the clothing of the horizontal knitted fabric can be provided.

Hereinafter, the knitted fabric, the knitting method of the knitted fabric, and the clothing according to the present invention will be described.
1 (a) and 1 (b) show a boxer pant 1 which is an example of a garment made of a weft knitted fabric according to the present invention.

  The boxer pants 1 are configured using a tubular knitted fabric of a tengu structure knitted using a single knitting machine. The circumferential length of the tubular knitted fabric is set to a size corresponding to the circumferential length of the wearer's body. That is, with respect to the cylindrical piece knitted fabric obtained by cutting the cylindrical knitted fabric, the waist portion 2 is formed at the upper portion thereof, and the left and right leg tubular portions 3 are formed at the lower portion thereof. The crotch part 4 separately cut between the two is sewn.

  The boxer pant 1 is a molded garment that is integrally knitted with a horizontal knitted fabric in which a front yarn as a decorative yarn and a back yarn having a higher elasticity than the front yarn are knitted by knitting. The cylindrical knitted fabric is provided with a convex portion having a three-dimensional shape so as to fit with a uniform contact pressure corresponding to the portion and the periphery thereof. That is, as shown in FIGS. 1A and 1B, the convex portion 6 is formed at the position corresponding to the lower abdomen of the front body 5, and the convex portion 9 is formed at the left and right hip corresponding positions of the rear body 8. ing.

  The convex portions 6 and 9 are continuously knitted on the flat portion 11 of the body fabric constituting the front body 5 and the back body 8, and the convex portions 7 and 10 are tucked so that the fabric reaches the convex portion 9 sufficiently. The excess fabric is turned to the convex part 6.9, the pressure applied to the convex parts 6 and 9 is reduced, and the flat part 11 is made denser than the convex parts 6 and 9, so that the flat part 11 is configured to increase the contact pressure.

  FIGS. 1A and 1B show photographs of a boxer brief 1 that is a sample of such a molded garment. The boxer brief 1 is made of polyester yarn of 33 to 168 dtex used as a decorative yarn serving as a front yarn, and a single covered cover obtained by wrapping nylon yarn or the like around 10 to 78 dtex core yarn polyurethane around an elastic yarn used as a back yarn. Yarn (SCY) is used. That is, the back yarn may be a yarn having a higher elasticity than the front yarn.

  The decorative yarn used as the front yarn is not limited to polyester yarn, and synthetic yarn such as nylon, natural fiber such as cotton, regenerated fiber yarn such as rayon and cupra, and mixed yarn thereof can also be used. The elastic yarn used as the back yarn is a high elongation such as a covering elastic yarn in which a core yarn made of polyurethane-based elastic yarn is covered with a filament yarn or processed yarn of synthetic fiber, or a bare yarn made only of polyurethane-based elastic yarn. Can be used. The covering elastic yarn is not limited to a single covered yarn (SCY), and a bare polyurethane yarn or a filament twisted yarn (FTY) including a double covered yarn (DCY) is preferably used.

  As shown in FIGS. 1 (a), 1 (b), and 3 (a), the front body 5 is changed to two colors by switching the front thread at the left and right boundary portions of the front body 5 and the back body 8. The back body 8 is knitted in one color. In this example, the light blue polyester yarn and the dark blue polyester yarn are switched at the left and right boundary portions of the front body 5 and the back body 8. That is, there is provided a yarn switching section 12 for switching the front yarn knitted in the course direction to another front yarn.

  As shown in FIGS. 3 (c) and 3 (d), the yarn end is exposed in a tuft shape in the yarn switching portion 12 on the back side of the boxer pants 1 by the yarn switching, but FIGS. 3 (e) and 3 (f). As shown, the yarn ends are cut to a length of about 1 to 2 mm. In this state, the thread end may protrude from the surface of the cloth as it is repeatedly worn and selected multiple times.

  Therefore, as shown in FIG. 4, the weft knitted fabric has at least one course in units of a predetermined number of courses, and at least two continuous stitches of the second and fifth stitches before and after the yarn switching unit 12 are sandwiched. The eyes (the stitches that are not hatched in the figure) are knitted, and the front and back (the hatched stitches in the figure) are knitted.

  When at least two stitches on the front and rear sides of the yarn switching unit 12 are knitted (float knitted), the tension of the elastic yarn, which is the back yarn, acts on the portion, and the knitted fabric is drawn toward the yarn switching unit 12 Be able to. Since such a course is repeated in units of a predetermined number of courses, the stitches of the course knitted between the welt-knitted stitches protrude to the front side, and as a result, the wale direction across the yarn switching portion Two linear protrusions 13 and 14 are formed.

  In such a state, even if the yarn end 15 of the front yarn that has been switched to the yarn may protrude to the surface side of the knitted fabric, it is covered with the two linear convex portions 13 and 14, There will be no noticeable appearance.

  In the photograph of FIG. 3B in which FIG. 3A is enlarged, the two convex portions 13 and 14 that are linear in the vertical direction are confirmed across the thread switching portion 12 that is linearly positioned in the vertical direction. it can.

  As shown in FIG. 4, it is preferable that a course having a portion to be knitted and a course made only of knit knitting are alternately arranged in units of one course, but 1 to 2 to 5 course units made only of knit knitting. A mode in which a coarse welt is knitted may be used.

  In addition, it is preferable that only the second stitch among the second and fifth stitches before and after the yarn switching unit 12 is sandwiched, but all may be welded. In this case, the protruding degree of the convex parts 13 and 14 appearing across the thread switching part 12 is increased. In the case of a welt knitting with only one stitch, sufficient convex portions 13 and 14 are not formed, and the covering effect of the yarn end protruding to the front side is weakened.

  FIG. 3A illustrates an example in which the thread switching unit 12 is linearly formed in the wale direction at the boundary between the front body and the back body, but the thread switching unit is formed at the boundary between the front body and the back body. However, the present invention is not limited to the embodiment, and may be an embodiment formed continuously in a curved shape. Even when the pattern is switched by thread switching, two linear convex parts are formed in a straight line or curved line across a thread switching part that is continuously formed in a straight line or curved line. Even if the yarn end protrudes to the front side in each yarn switching portion, the yarn end is covered with two linear convex portions.

  As is clear from the above description, the method for knitting a horizontal knitted fabric according to the present invention is a method for knitting a horizontal knitted fabric in which a front yarn and a back yarn having a larger elasticity than the front yarn are knitted by knitting, A yarn switching step of switching a front yarn knitted in the course direction to another front yarn at a predetermined yarn switching portion, before and after the yarn switching step, the second and fifth stitches before and after the yarn switching portion A yarn end covering step of welt knitting at least two continuous stitches and knitting the front and back thereof.

  In the embodiment described above, the weft knitted fabric is knitted in a cylindrical shape with a single circular knitting machine, but the weft knitted fabric according to the present invention is also used for a weft knitted fabric knitted using a weft knitting machine. Needless to say, it is applicable.

  The clothing according to the present invention is not limited to the boxer pants, and may be formed of the above-described weft knitted fabric, and can be widely applied to trousers, swimwear, body suits, shorts, pantyhose, girdle, brassiere, camisole, and the like.
