DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Tights worn from autumn to spring are:
It is thick enough to hide the ground color of the feet and, unlike pantyhose and the like, in which the skin color utilizing the bare skin color is the mainstream, various colors can be enjoyed. In recent years, in addition to monochromatic dyes, those with flashy patterns, such as stripes and checks, and conversely, marbled chic ones have become available.

[0003] The above marbled tights include knitted marbled yarns of partially different colors.
This product has a high product price because marbled yarn is expensive. Also, the marbling pattern is rough and not dense. On the other hand, as a method of obtaining a dense marbling pattern at a low cost, recently, a polyurethane elastic yarn is used as a core yarn, and a polyester yarn and a nylon yarn are knitted using a double-covered yarn, and this is dyed with an acid dye. A method of dyeing with a dye has been proposed. For example, as shown in FIG. 2, a knitted fabric consisting of a double covering yarn obtained by first covering a polyester yarn 2 on a polyurethane elastic yarn 1 and covering the same with a nylon yarn 3 is dyed with an acid dye. Is strongly dyed by the acid dye as shown by the diagonal lines, and the polyester yarn 2 is not dyed. Therefore, a difference in shading occurs as shown in the figure, and a fine marbling tone is obtained as a whole. 2, the same effect can be obtained by using the nylon yarn 3 to be dyed inside and using the polyester yarn 2 outside.

[0004]

However, in the above-mentioned method, one of the yarns may appear or hide too much on the surface depending on the conditions and the number of times of covering, so that a fine marbling tone cannot be obtained, and a fine marbling tone cannot be obtained. Stable supply of marbling tights has been difficult in practice.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to provide dense and marbled socks stably and at low cost.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a method of forming a polyester yarn of 10 to 30 denier and a nylon yarn of 10 to 40 denier with a twist of 100 to 100.
A knitted yarn twisted at 1200 tpm is knitted by a covering yarn obtained by covering a polyurethane elastic yarn of 15 to 40 denier, and in a knitted fabric state, it is selectively dyed to either a polyester yarn or a nylon yarn. Dyed with a dye having a wearing characteristic, one of the polyester yarn and the nylon yarn exhibits a ground color or a light color and the other exhibits a dark color, and a marbled sock in which a color pattern is formed in a marbling tone as a whole. The first point is 1
A step of preparing a covering yarn obtained by covering a ply twisted yarn obtained by twisting a polyester yarn of 0 to 30 denier and a nylon yarn of 10 to 40 denier with a twist number of 100 to 1200 tpm to a polyurethane elastic yarn of 15 to 40 denier. And a step of knitting using the covering yarn, and a step of dyeing the knitted product with a dye having selective dyeing properties for one of polyester yarn and nylon yarn. A second aspect of the present invention is a method for producing socks.

[0007]

The present inventors have conducted a series of studies on a method for stably and inexpensively providing dense marbled socks. As a result, instead of using a covering yarn in which a polyester yarn and a nylon yarn are alternately wound, a polyester yarn and a nylon yarn of a specific thickness are used.
If you use a special covering yarn that is wrapped with a ply twisted yarn with a specific number of twists, the polyester portion and the nylon portion will always appear alternately and densely on the yarn surface, so this yarn must be used. When knitting tights and the like, and dyeing using a dye that can selectively dye one of the polyester yarn and the nylon yarn to a dark color,
The present inventors have found that a dense and beautiful marbling color pattern can be obtained, and have reached the present invention.

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. As a result, a covering yarn in which the surface is covered with a ply-twisted yarn in which polyester yarns and nylon yarns are alternately twisted and polyester portions and nylon portions are mixed in a finely dispersed state is obtained. Next, the covering yarn is knitted according to a usual method to form a target sock, and then dyed in a dye bath using an acid dye. The acid dye has no dyeing property with respect to polyester, but shows dyeing property only with nylon. Therefore, in the dyed knitted product, as shown in FIG. 1, only the nylon yarn 6 of the covering yarn 5 constituting the stitch is dyed dark, and the polyester yarn 7 remains the ground color. It is. In addition, 1 is a polyurethane elastic yarn which is a core yarn. Therefore, very dense and beautiful marbling socks can be obtained.

In the above-mentioned manufacturing method, in order to realize a dense and beautiful marbling tone, a polyester filament of 10 to 30 d (denier) is used as the polyester yarn 7 constituting the twisted yarn, and a 10 to 30 d (denier) polyester filament is used as the nylon yarn 6.
A 40d nylon filament must be used. The polyurethane elastic yarn used as the core yarn must be 15 to 40d.

The laying conditions for twisting the polyester yarn 7 and the nylon yarn 6 are appropriately set, and there is no problem with single twisting or double twisting. However, although the number of twists depends on the thickness of the yarn used, it is 100 to 1200 tp.
It is necessary to set m. The covering conditions for winding the ply-twisted yarn thus obtained around the polyurethane elastic yarn 1 are also set appropriately, and single covering or double covering may be used.

Further, in the above-mentioned production method, dyeing is carried out using an acid dye which shows dyeability only to nylon. However, the dyeability is not limited to acid dyes, and the dyeability to polyester is poor. Any dye may be used as long as it shows the following. Conversely, a dye having poor dyeing properties to nylon and exhibiting excellent dyeing properties only to polyester can be used because the same effect is obtained.

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

Next, an embodiment will be described.

[0015]

Example 1 First, a polyester yarn of 20d and a polyester yarn of 30d
With a nylon thread of 600 tpm,
A plied yarn was obtained.

Next, the ply-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 an ordinary method, and then dyed by 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 very interesting.

[0019]

As described above, the present invention provides a hosiery using a special covering yarn in which a polyester yarn and a nylon yarn having a specific thickness are plied with a specific number of twists and a special covering yarn is used. After knitting, the polyester yarn and the nylon yarn are dyed using a dye that selectively dyes either one of the polyester yarn and the nylon yarn. Therefore, in the marbled socks of the present invention, the polyester part and the nylon part always appear alternately at a uniform and dense interval on the yarn surface constituting the stitch, one of which is dyed dark and the other is light-colored. Alternatively, since it is dyed in the ground color, it has a very dense and beautiful marbling color pattern as a whole. Moreover, the above marbled socks can be easily obtained by dyeing a knitted product in a single bath, so that the production cost is low and an inexpensive product can be stably supplied. Then, at the time of the above-mentioned dyeing, only by changing the dye to be used, it is possible to easily obtain a marbled sock with a different color tone, so that it is possible to efficiently perform low-cost, high-mix low-volume production according to needs.
