Description

FIBER TREATMENT AGENT COMPOSITION

The present invention relates to a fiber treatment composition that imparts excellent texture to the fiber, and to a fiber that provides a superior texture and texture when a consumer wears a final product made of the fiber. More specifically, it relates to an amphipatic lipid-containing fiber treating agent composition which is a solid particle having a specific average particle diameter advantageous for fiber treatment, a fiber having the above-mentioned bipolar lipid on the surface, and a method of treating the fiber.

Japanese Patent Application Laid-Open No. 8-60547 discloses a skin care textile product to which a serine-containing protein is fixed. In addition, Japanese Patent Application Laid-Open No. 2001-146680 discloses a finishing composition for textiles containing a nonionic bipolar material. More specifically, the nonionic bipolar material is ceramide, and preferably the ceramide is present in the composition in the form of emulsified particles having a particle diameter of 1,000 nm or less together with other compounding components. The compositions disclosed herein have been reported to exhibit good emulsification stability over time to prevent the precipitation of ceramides and good binding and cohesion of the ceramides to the treated fibers due to these properties. Treated textile products also improve the skin's moisture retention when worn by consumers. Thus, the ceramides disclosed in this document do not exist as solids.

However, these techniques are not sufficient, i.e., the amount of ceramide that is sufficient to provide a sufficient effect is difficult to remain on the fiber, the wash durability is low, and the texture to the fiber cannot be improved without sacrificing other properties.

It is an object of the present invention to stably retain bipolar lipids having a skin care effect on fibers, to impart excellent texture to the fibers, and to show a moisturizing effect on the skin when the consumer wears the final product made of the fibers, It is to provide a fiber treatment composition for imparting a good touch to the skin in contact with.

 The present invention contains a bipolar lipid having a hydroxyl group (s) and an amide group (s) in the molecule, the lipid is to provide a fiber treatment composition is a solid particle having an average particle diameter of 1 ~ 100 ㎛.

In addition, the present invention provides a fiber treating agent composition further comprising at least one member selected from the group consisting of a surfactant and an aqueous medium, in addition to the fiber treating agent composition.

The bipolar lipids of the present invention, due to their particular shape (solid particles having an average particle diameter of 1 to 100 μm), do not tend to exist inside the treated fibers, and thus adhere effectively to the fiber surface as compared to the dissolved or emulsified bipolar lipids. It is believed that Further, when the fiber treatment process includes a washing step or a rinsing step, the dissolved or emulsified bipolar lipids are easily removed through washing. However, according to the present invention, since the bipolar lipids are solid particles having a suitable size, they cannot be easily washed and thus have improved lipid retention in the fibers. For this reason, it is judged that the fiber treated with the fiber treatment composition of the present invention gives a good texture to the resultant fabric and gives a good texture to the skin.
