JPH07173746A - Cuff for knit shirt proofed for extension - Google Patents

Abstract

PURPOSE:To obtain a less-expensive cuff for a knit shirt, having extension proof structure and free from the shrinkage of elastic yarns caused by a force generated when a linking yarn is removed. CONSTITUTION:This cuff for knit shirt is composed of a bag-shaped part 2 knitted of spun yarns and a rib part 3 continuing from it. 5-20% of the rib part 3 is knitted of elastic yarns S together with spun yarns C and the other rib part is knitted of spun yarns C to constitute extension proof structure.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cuff for stretch-preventing knit shirts, and more particularly to a polo shirt cuff.

[0002]

2. Description of the Related Art Conventionally, a cuff for a polo shirt knitted with cotton spun yarn is easily stretched by devising the thread usage suitable for the polo shirt body material, the gauge and knitting conditions, for example, the stitch length of the rib part of the bag part. The knitting was done so that it would be in a state. However, the cuffs made in this way gradually deteriorate in stretch back property (recoverability) as the number of washings increases, and eventually the cuffs become fully extended, degrading the quality and commercial value. It was

[0003]

In recent years, in order to improve the stretch-back property, a means for knitting an elastic yarn by aligning it with a cotton spun yarn has been proposed. However, the elastic yarn and the cotton spun yarn are combined. Not only is it difficult to control the tension and the knitting means is difficult, but even if knitting is performed, elastic yarns will be exposed in places on the knitted fabric surface, and the cotton side In the case of single-sided dyeing, the undyed elastic yarn was irritated and the quality was degraded. Further, even when both the elastic yarn and the cotton spun yarn are dyed, color matching is extremely difficult, and it is not possible to sufficiently solve the unevenness of the knitted fabric surface.

In general, when the cuffs are continuously knitted, a knitting yarn is knitted between one cuff and another cuff, and after the knitting, the tethering yarn is removed to produce a large number of cuffs. However, since the cuffs that use elastic threads use expensive elastic threads, the cost is high, and there are drawbacks such as the elastic threads shrinking under the force of the removal when removing the connecting thread, Not only the quality of the product is deteriorated, but also the work of pulling out the connecting yarn becomes difficult.

[0005]

SUMMARY OF THE INVENTION In view of the above situation, the present invention has five rib parts which are continuous with a bag part knitted from spun yarn.
A 20% portion is knitted with elastic yarn and spun yarn together, and the other ribs are knitted with spun yarn, which is a cuff for a stretch-prevented knit shirt.

[0006]

In the present invention, since the elastic yarn is knitted together with the spun yarn in part, the elastic yarn not only has a sufficient stretch-back property, but the elastic yarn has a rib portion 5 which is substantially in the center of the cuff. Since it is used only in a portion of ~ 20%, when pulling out the connecting yarn, the pulling force does not reach the elastic yarn, and it is possible to obtain a good product that is not adversely affected by the pulling force. Work becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a cuff for a knit shirt which is stretch-extended and prevented, and the cuff 1 for a knit shirt comprises a bag portion 2 and a rib portion 3. The bag portion 2 is knitted only from the cotton spun yarn, and the rib portion 3 is knitted from the cotton spun yarn C and the elastic yarn S in a portion of 5 to 20% (3 to 5 courses) directly connected to the bag portion 2. The other rib portion 3 is a cotton spun yarn C
It is organized by only. In the portion knitted by using the elastic yarn S and the cotton spun yarn C together, the elastic yarn S is not exposed on the surface and only the cotton spun yarn C is exposed.

The reason why the elastic yarn S is limited to be knitted in the rib portion 3 of 5 to 20% is that the washing resistance is poor when it is less than 5% and the stretch back property is increased as the number of times of washing is increased. (Recoverability) is reduced, and the effect of using elastic yarn is not obtained. On the other hand, if it is more than 20%, the washing resistance and the stretch back property (recoverability) are good, but not only economically unfavorable due to high cost, but also the work of removing the connecting yarn becomes difficult. It is a thing.

In the knitting of the cuffs of the present invention, the cotton spun yarn C is fed to the flat knitting machine from one yarn feeder of the double yarn feeder, the bag portion 2 is knitted first, and after the bag portion 2 is finished knitting. Knit the rib portion 3.
At this time, the elastic yarn S is fed from the other yarn feeder of the double yarn feeder, and the elastic yarn S and the cotton spun yarn C are fed together by different tensions, so that 3 to 5 courses together. Knit.
At this time, the tension is adjusted so that the elastic yarn S is not exposed on the surface and only the cotton spun yarn C is exposed. After this formation,
Only the supply of the elastic yarn S is stopped, and thereafter, the rib portion 3 is knitted only with the cotton spun yarn C. After knitting the rib portion 3, after knitting the connecting portion 4 with a connecting thread, knitting of one cuff is completed, and by continuing the above operation, a large number of cuffs are continuously knitted. You can

Concrete Example In a flat knitting machine, a cotton spun yarn 10 from one of the yarn feeders of a double yarn feeder
0% 40 // 7 (40 / 1- 7 yarns are aligned), first knit the bag part for 2 courses, then feed the polyurethane yarn 20d from the other yarn feeder of the double yarn feeder. The rib portion 3 was knitted together with the cotton spun yarn only for 4 courses. Next, only the polyurethane yarn is stopped, the remaining 34 courses (eyes) of the rib portion 3 are knitted with cotton spun yarn, and the joint portion 4 is continuously knitted with the polyester filament 150d to make one polo shirt cuff width. 27
The knitting of cm and length 3 cm (38 courses) was completed. continue,
After knitting a number of cuffs by repeating the above knitting, the connecting yarn was removed and divided into individual cuffs.

In the cuffs thus obtained, the bag portion 2 is knitted with cotton spun yarn, and 4 courses (11%) of the rib portion 3 continuing to this are knitted with polyurethane yarn and cotton spun yarn, etc. The 34 courses (89%) of the rib portion 3 are knitted with cotton spun yarn, the polyurethane yarn is not exposed on the surface, and the polyurethane yarn is far from the tether yarn, so the tether yarn is It was of good quality with no shrinkage of the polyurethane yarn due to the removal of the yarn. further,
This cuff was repeatedly washed 50 times with the JIS L-0217 103 method home washing method, and the stretch back property (recoverability) was examined. As a result, it was found that the cuff was not in a fully extended state and could maintain good quality. done.

[0012]

As is apparent from the above description, the cuff for a knit shirt according to the present invention has a durable stretch-back property (recovery power), and the quality is also improved by the yarn removing process performed after the cuff knitting. Even when dyed by the one-bath dyeing method which is the same dyeing method as the conventional one, the polyurethane yarn is not exposed on the surface without causing any damage, so that good dyeing can be performed. Further, since the elastic yarn is used only for 5 to 20% of the rib portion, it is possible to exhibit excellent effects in practical use such as economical cost.
