Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to marbling socks having a marbling color pattern formed on a knitted fabric and a method for producing the same.

[0002]

[Prior Art] Tights worn from autumn to spring
It is thick enough to hide the background color of the feet, and unlike the Pan-Taste Talking, where skin colors that take advantage of the color of the bare skin are the mainstream, various colors can be enjoyed. In addition to monochromatic dyes, recently, those with flashy patterns such as stripes and checkers, and conversely, frosted and shiny patterns are also available.

[0003] As the above-mentioned marbling-like tights, there is one in which marbled yarns of different colors are knitted
This product has a high product price because the marbled yarn is expensive. Also, the marbled pattern is rough and not precise. On the other hand, as a method of obtaining a dense marbled pattern at a low cost, recently, polyurethane elastic yarn is used as a core yarn, and a polyester yarn and a nylon yarn are double-covered with the yarn to knit it. A method of dyeing is proposed. For example, as shown in FIG. 2, a polyurethane elastic yarn 1 is first covered with a polyester yarn 2 and then a double covering yarn covered with a nylon yarn 3 is dyed with an acid dye to obtain only a nylon yarn 3. Is dyed deeply with an acid dye as shown by the diagonal lines, and the polyester yarn 2 is not dyed, so that a shade difference occurs as shown in the figure, and a fine marbling tone is obtained as a whole. Incidentally, contrary to the case of FIG. 2, the same effect can be obtained by using the dyed nylon thread 3 on the inside and the polyester thread 2 on the outside.

[0004]

However, in the above method, depending on the covering condition and the number of times, one of the yarns is too exposed or hidden on the surface, and a fine marbling tone cannot be obtained. A stable supply of marbled tights has been difficult as a practical problem.

The present invention has been made in view of the above circumstances, and an object thereof is to provide dense marbled socks with stability and at low cost.

[0006]

In order to achieve the above object, the present invention is knitted with a covering yarn obtained by covering a polyurethane elastic yarn with a plied yarn obtained by ply twisting a polyester yarn and a nylon yarn, The first gist is marbling socks in which one of the polyester yarn and the nylon yarn has a ground color or a light color and the other has a dark color, and a color pattern is formed in a marbling tone as a whole. A step of preparing a covering thread obtained by covering a polyurethane elastic thread with a plied yarn obtained by plying a nylon thread, a step of knitting using the covering thread, a step of knitting the knitted product with a polyester thread and a nylon thread The second gist is a method for producing marbled socks, which comprises a step of dyeing with a dye having a selective dyeing property for one of A step of preparing a covering yarn obtained by covering a polyurethane elastic yarn with a twisted twisted yarn in which a polyester yarn and a nylon yarn are twisted, and the covering yarn is selectively dyed with respect to one of the polyester yarn and the nylon yarn. A third aspect of the present invention is a method for producing marbled socks, which comprises a step of dyeing with a dye having a dressing property and a step of knitting using the dyed covering yarn.

[0007]

That is, the present inventors have conducted a series of researches on a method for providing dense marbled socks with stability and at low cost. As a result, instead of using a covering yarn in which polyester yarns and nylon yarns are wound alternately, using a special covering yarn in which a twisted yarn in which a polyester yarn and a nylon yarn are twisted in advance is wound, Since polyester parts and nylon parts always appear alternately on the thread surface, use this thread to knit tights, etc., and use a dye that selectively dyes either polyester thread or nylon thread in a dark color. It was found that when dyed with it, a dense and beautiful marbling color pattern was obtained. Further, they have found that a similar marbling color pattern can be obtained even when the covering yarn is dyed with the above dye at the yarn stage and then knitted.

Next, the present invention will be described in detail.

First, the marbled socks of the present invention are obtained, for example, as follows. That is, first, a twisted yarn obtained by twisting a polyester yarn and a nylon yarn is wound around a polyurethane elastic yarn serving as a core yarn to perform covering. Thus, the surface is covered with the plied yarn in which the polyester yarn and the nylon yarn are alternately twisted, and the covering yarn in which the polyester portion and the nylon portion are finely dispersed is obtained. Next, the covering yarn is knitted according to a usual method to make it into a desired shape of socks, and then dyed in a dyeing bath using an acid dye. The acid dye has no dyeing property with respect to polyester, but has dyeing property only with nylon. Therefore, in the dyed knitted fabric, as shown in FIG. 1, only the nylon yarn 6 portion of the covering yarn 5 constituting the stitch is dyed dark and the polyester yarn 7 portion remains the ground color. Is. In addition, 1 is a polyurethane elastic yarn which is a core yarn. Therefore, it is possible to obtain very fine and beautiful marbled socks.

In the above manufacturing method, it is preferable to use a polyester filament of 10 to 30 d (denier) as the polyester yarn 7 constituting the plied yarn. As the nylon thread 6, it is preferable to use a nylon filament of 10 to 40d. And, as the polyurethane elastic thread used as the core thread, 1
It is preferable to use the one of 5 to 40d.

Further, the ply-twisting conditions for ply-twisting the polyester yarn 7 and the nylon yarn 6 are appropriately set, and either single-twisting or loose-twisting may be used. However, depending on the thickness of the thread used, the number of twists is 100 to 1200 tp.
It is preferable to set to m. The covering conditions for winding the thus obtained plied yarn around the polyurethane elastic yarn 1 are appropriately set, and either single covering or double covering may be performed.

Further, in the above-mentioned manufacturing method, dyeing is carried out only with nylon by using an acid dye showing dyeability, but not limited to acid dyes, the dyeability with polyester is poor, and only nylon has excellent dyeability. Any dye may be used as long as it shows. On the contrary, even a dye having poor dyeability to nylon and having excellent dyeability only to polyester can be used because similar effects can be obtained.

In the above manufacturing method, dyeing is performed after knitting, but the covering yarn 5 itself is dyed with the same dye as above, and only the nylon portion is dyed in a dark color.
Knitting may be performed using this thread.

The socks to which the present invention is applicable include various socks such as tights, stockings and socks. However, since a covering yarn having a strong compressive force is used, it is suitable to apply to support type tights.

Next, examples will be described.

[0016]

Example 1 First, 20d polyester yarn and 30d
Nylon yarn of No.2 is twisted under the condition of 600 tpm
Gotten a twisted yarn.

Next, the above-mentioned twisted and twisted yarn was wound around a 20d polyurethane elastic yarn under predetermined conditions to obtain a single covering yarn. Using this covering yarn, support tights were knitted according to a usual method and dyed with a drum dyeing machine.

The support tights thus obtained had a beautiful marbling color pattern in which the shades of color were densely and uniformly dispersed, and were of great interest.

[0019]

Example 2 The same single covering yarn as in Example 1 was obtained and dyed with a cheese dyeing machine.

Next, using the above-mentioned dyeing covering yarn, support tights were knitted according to a usual method.
The support tights thus obtained had a beautiful marbling color pattern in which the shades of color were densely and uniformly dispersed and were of great interest.

[0021]

As described above, according to the present invention, the socks are knitted up using the special covering yarn in which the twisted yarn obtained by previously twisting the polyester yarn and the nylon yarn is wound, and then the polyester yarn and the nylon yarn are knitted. Either one of the yarns is dyed with a dye that selectively dyes, or the special covering yarn is dyed with the dye and then knitted into socks. Therefore, in the marbled socks of the present invention, the polyester part and the nylon part are always alternately shown on the yarn surface constituting the stitch, one of which is dyed dark and the other is light or ground. As it is dyed in color, it has a very fine and beautiful marbled color pattern as a whole. Moreover, the above-mentioned marbled socks can be easily obtained by dyeing the yarn or the knitted product in one bath at the yarn stage or the knitted item stage, so that the manufacturing cost is low and the inexpensive product is stable. Can be supplied to.
