ける性能の向上が強く望まれている。BACKGROUND OF THE INVENTION It is well known to treat fabrics with a fluorine water repellent to impart water repellency. The conventional water-repellent treated cloth is often discussed in terms of durability depending on the number of washings, and in fact, has a drawback that the water repellency after 50 washings is extremely reduced. In addition, the water repellency of a conventional water-repellent cloth often deteriorates due to stains, sebum, abrasion, etc. during repeated wearing, and water permeates between the yarn bundles of the cloth and the surface of the cloth often becomes wet. Therefore, it is strongly desired to improve the performance of the water-repellent processed cloth at the practical use level.

A thermoplastic resin of 10 kg / cm 2 or less is mixed with 30 to 100% by weight of a silicone water repellent and / or a fluorine water repellent and 5 to 30% by weight of a polyisocyanate cross-linking agent based on the resin solid content. This is achieved industrially by using an impermeable durable water-repellent processed cloth coated with an organic solvent solution.

However, if the fiber surface of the yarn bundle of the fabric is simply wrapped by coating and the gap between the fibers of the yarn bundle is filled to form a film, ordinary resin coating may be performed, but in the present invention, In order to have the same texture as ordinary water repellent finish, it can be soft enough as a coating material even at low temperature, the glass transition temperature of the polymer is 0 ° C or lower, and the 100% modulus is 10 kg / cm 2 The following thermoplastic resins that do not form a very strong film are used. In the present invention, acrylic resin and urethane resin are preferably used as the thermoplastic resin. As the acrylic resin and urethane resin, those obtained by copolymerizing a silicone compound or a fluorine compound are particularly preferable. In order to impart sufficient water repellency to the thermoplastic resin, it is 30 to 1 relative to the resin solid content.
It is necessary to mix 00% by weight of silicone water repellent and / or fluorine water repellent. As these silicone water repellents and / or fluorine water repellents, not only solvent-soluble types but also those which can be uniformly dispersed in a thermoplastic resin can be used. In the present invention, it goes without saying that the organic solvent solution containing the thermoplastic resin may be a dispersion liquid.

It is necessary to use 30% by weight. Examples of the polyisocyanate-based crosslinking agent include TDI-based or HMDI-based polyisocyanate-based crosslinking agents.

To apply a resin coating to a water-repellent finish, the resin must be an organic solvent solution, and in order to make it feel like a normal water-repellent finish, it needs to be processed with an oil-repellent fluorine water repellent. is there. No silicone water repellent can be used for this water repellent treatment. The fluorine water repellent treatment is carried out with the fluorine water repellent agent in a solution or emulsion state.

It is important to eliminate the film feeling as much as possible for the impermeable durable water repellent treatment having the property. For that purpose, the concentration of the thermoplastic resin in the organic solvent solution containing the thermoplastic resin is 5 to 5.
It is preferably 15% and the viscosity is 1000-5.
