Abstract

PROBLEM TO BE SOLVED: To provide a Japanese clothes concurrently having both functions of water-repellency and antistaticity by coating the surface of fiber with a specific polymer film mainly composed of polyalkylene oxide segments. SOLUTION: A treating solution is prepared by mixing a polymer obtained using a monomer having at least two or more acrylic and/or methacrylic groups such as ethylene glycol di(meth)acrylate as the both terminals or one terminal of a main chain consisting mainly of polyalkylene oxide segments or a side chain of the main chain with at least one selected from an acrylic copolymer containing polyfluoroalkyl groups, an aminoplast resin such as trimethylol melamine and a urethane resin containing a polyfunctional block isocyanate such as tolylene diisocyanate. A crepe woven fabric of a polyester fiber is incorporated with the treating solution and subsequently the fabric is treated under heating to form a film on the surface of the fiber. Thus, a cloth for a Japanese clothes having a water repellency of >=70 points and a frictional electrification voltage of <=2,000volt after 20 times of washing is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Japanese garment which has both water repellency and antistatic properties which are durable to washing. More specifically, a highly functional kimono with two functions: a water-repellent effect that prevents rain and splashes on rainy days, and an anti-static effect that prevents the generation of static electricity due to the friction between the cloth when worn. It is about.

[0002]

[Prior Art] Kimono is a garment from ancient Japan,
The mainstream is made of 100% natural fibers such as silk and hemp.
There was a tendency not to like incorporating new functions.
However, because of the complexity of wearing methods and the difficulty of care after wearing, it has been suggested to leave Japanese clothes, and in order to stop this, mixed fibers with synthetic fibers, and Japanese clothes consisting of interwoven and 100% synthetic fibers have been proposed. . With such a trend, functionality has come to be required even in Japanese clothes, tea during meals,
Prevents stains from food when coffee spills,
Japanese clothes with a temporary water repellent to prevent splashing of rain and mud when going out in the rain have become common. However, such a water-repellent treatment has poor durability, and it is necessary to apply a water-repellent agent each time cleaning is performed, which requires labor and a processing cost, and an improvement has been required.

In addition, Japanese clothes have the problems that they have large sleeves and that there are many parts such as the bottoms where the cloths rub against each other, and static electricity is easily generated. In particular, in the case of a tail, it is very difficult to walk when the tailing is bad due to the generation of static electricity.

From the above, it can be said that antistatic property is an essential function of a kimono.

However, conventionally, it is difficult to obtain both the water repellency and the antistatic property at the same time, the water repellency is the property obtained by making the fiber hydrophobic, and the antistatic property makes the fiber hydrophilic. By doing so, the electrical resistance of the fiber surface can be reduced and the obtained performance can be obtained. It was extremely difficult to achieve both of these performances that are completely contradictory.

[0006] Generally, a method of using a polyelectrolyte antistatic agent such as a cationic surfactant or a polycation derivative at the time of water repellent treatment is performed, but the antistatic property is temporary and is washed. It was poor in durability. In addition, since the water repellent agent is also dropped off at the same time as the antistatic agent is dropped off, the water repellency and the antistatic property are greatly deteriorated after washing.

[0007]

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to provide a Japanese garment having both washing durability and water repellency and antistatic properties.
