Description

Water-dispersible composition for fiber processing

Technical Field

The invention relates to a water-dispersible composition for fiber processing.

Background

Conventionally, in order to impart various functions such as water repellency and antifouling property to fibers, fibers have been processed using various fiber processing agents in many cases.

For example, as a method for imparting water repellency to fibers, a water repellent agent is generally used for treatment. As the water repellent agent, particularly, a fluorine-based water repellent agent having a fluorine atom is widely known, and a fiber product which imparts water repellency to the surface thereof by treating the fiber product or the like with the fluorine-based water repellent agent is known.

The fluorine-based water repellent is usually produced by polymerizing or copolymerizing a monomer having a fluoroalkyl group. Although fiber products treated with a fluorine-based water repellent exhibit excellent water repellency, there are environmental problems in that a monomer having a fluoroalkyl group is hardly decomposable.

Therefore, in recent years, research into non-fluorine-based water repellents that do not contain fluorine atoms has been conducted. For example, patent document 1 proposes a water repellent agent comprising a specific non-fluorine-containing polymer containing, as a monomer unit, a (meth) acrylate having 12 or more carbon atoms in an ester moiety. In addition, patent document 2 proposes a soft water repellent agent containing an amino-modified silicone and a polyfunctional isocyanate compound. However, since the fibers processed using these water repellent agents have very small frictional resistance between fibers, there is a problem that slipping property (performance of preventing the phenomenon of stitch dislocation in wearing in clothing and the like) is lowered. Further, the processed fiber tends to be hard, and thus the hand cannot be said to be sufficient. In addition, when the processed fiber is bent or rubbed, there is a problem that a water repellent film on the fiber is cracked or peeled off, and this portion is whitened by diffuse reflection of light, so-called chalk marks are generated, and the appearance is greatly impaired.

Further, as other functional imparting to the fiber, antifouling processing is exemplified. Conventionally, various antifouling processes have been proposed to prevent stains from adhering to fibers or to facilitate removal of the adhering stains.

As the above-mentioned antifouling processing, for example, non-fluorine-based antifouling (SG, soil Guard; performance of making it difficult for stain components to adhere to the fiber surface) processing is known in which the fiber surface is coated with a stain resistance imparting agent such as a silicone-based processing agent. When the SG processing is performed on the fiber, it becomes difficult for the liquid stains to adhere to the fiber surface. However, in such SG processing, since frictional resistance between fibers is reduced, there is a problem that slip properties of fibers are lowered and hand feeling is also deteriorated in the same manner as in the above water repellent processing.

Patent document 3 proposes an antifouling agent which is excellent in SG properties by attaching polysaccharides and modified organosilicate fine particles to a fiber material. But the slipping property of the fiber or its hand is not considered.
