Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dye composition, a dyeing method using the dye composition, and a protein fiber and a polyamide fiber dyed with the dye composition, and more specifically, it relates to an existing safety-assured A dye composition capable of being dyed by combining a specific dye with an artificial hair fiber material to match the hair color, a dyeing method using the same, and a human body dyed with the dye composition The present invention relates to a highly safe fiber material for artificial hair.

2. Description of the Related Art It is well known that the application of fiber materials to fields other than clothing is widely performed, for example, in the fields of automobile interior materials and interior materials. .. .

[0003] This application range is expanding more and more due to the progress of application development of dye materials suitable for the fiber material and its use, the differentiation of products, and the consumer's sense of luxury, and the application of fiber material for artificial hair. It is also widely practiced.

For example, it is well known to use a fiber material as an artificial hair of a wig, and for dyeing this fiber material, a dye suitable for a desired hair color, a dye having excellent fastness to sunlight, etc. Is being developed.

Recently, as an application example of the fiber material for artificial hair, a material cut into 1 mm or less is sprinkled on the thinned portion of the hair to hide the background and cut fibers. Products that have the effect of making your hair look thicker by sticking to your hair due to static electricity are bustling the market.

The chopped short fibers are dyed in a color suitable for the hair color, for example, black or brown, and because they can be easily used, they are attracting attention as artificial hair fibers that replace wigs.

As the short fibers, various fibers such as cellulose fibers, protein fibers and synthetic fibers are used, and they are dyed with a dye suitable for the fibers used.

For example, a product obtained by cutting rayon, which is a cellulose fiber, to a size of 0.3 to 0.5 mm and dyed it into an arbitrary color by using a direct dye, a reactive dye, a vat dye, or the like is on the market. ..

[0009]

However, the above-mentioned conventional fibers for artificial hair have the following problems.

That is, since the conventional dyes used for dyeing fibers for artificial hair are not guaranteed to be safe for the human body, it is not safe to use them for fibers that come into contact with the human body, especially the scalp. There is a problem that chemical substances, which have many unknown parts, come into contact with the scalp, and in the case of short fibers, they may get into the eyes and mouth, which is a question of safety.

Therefore, the appearance of fibers for artificial hair dyed with a dye whose safety to the human body is guaranteed has been long awaited.

[0012] However, there has been no successful case of producing a color suitable for the hair color by using a dye whose safety is guaranteed.

The present invention has been made in view of the above circumstances, and succeeded in combining existing specific dyes with guaranteed safety, and as a result, while maintaining the safety, the fiber material for artificial hair was maintained. A dye composition capable of being dyed in accordance with the hair color, a dyeing method using the same, and a fiber material for artificial hair, which is dyed by the dye composition and is highly safe for the human body It is a thing.
