Description

The present invention relates to an aqueous dispersion composition for fiber processing.

Conventionally, in order to impart various functions such as water repellency and antifouling property to a fiber, the fiber is often processed with various fiber processing agents.

For example, as water repellency imparting to fibers, treatment with a water repellent agent is common. As a water repellent, a fluorine-based water repellent having a fluorine atom is particularly well known, and a textile product whose surface is imparted with water repellency by treating the fluorine-based water repellent into a textile product or the like. It has been known.

The fluorine-based water repellent is generally produced by polymerizing or copolymerizing a monomer having a fluoroalkyl group. Textile products treated with a fluorine-based water repellent exhibit excellent water repellency, but monomers having a fluoroalkyl group are persistently degradable, which poses an environmental problem.

Therefore, in recent years, research has been conducted on non-fluorine-based water repellents that do not contain fluorine atoms. For example, Patent Document 1 proposes a water repellent agent composed of a specific non-fluoropolymer containing a (meth) acrylic acid ester having 12 or more carbon atoms in the ester portion as a monomer unit. Further, Patent Document 2 proposes a soft water repellent agent containing an amino-modified silicone and a polyfunctional isocyanate compound. However, the fibers processed with these water repellents have a problem that the frictional resistance between the fibers becomes very small, so that the slipperiness (the ability to prevent the seams from shifting during wearing in clothing etc.) is lowered. was there. Moreover, since the processed fibers tend to be hard, it cannot be said that the texture is sufficient. Further, when the processed fiber is bent or rubbed, the water repellent film on the fiber is cracked or peeled off, and the portion is whitened by diffused reflection of light, so-called chalk mark is generated and the appearance is greatly impaired. There was also a problem.

In addition, antifouling treatment can be mentioned as an example of imparting functionality to other fibers. Conventionally, various antifouling processing means have been proposed in order to prevent stains from adhering to fibers and to make it easier to remove the adhered stains.

As the antifouling treatment, for example, a non-fluorine-based SG (Soil Guard; performance that makes it difficult for stain components to adhere to the fiber surface) treatment in which the fiber surface is coated with a stain resistance imparting agent such as a silicone-based processing agent is used. Are known. If this SG processing is applied to the fiber, liquid stains are less likely to adhere to the fiber surface. However, in such SG processing, since the frictional resistance between the fibers becomes small, there is a problem that the slipperiness of the fibers is lowered and the texture thereof is also deteriorated as in the above-mentioned water-repellent treatment.

Patent Document 3 proposes an antifouling processing agent having excellent SG properties by adhering polysaccharides and modified organosilicate fine particles to a fiber material. However, the slipperiness of the fiber and its texture are not considered.
