Fiber structure

Abstract

[Problem to be Solved] To stably supply a fiber structure having excellent ashing durability, water / oil repellency and antifouling properties.[Solution] A fiber structure characterized in that each of the single fibers used in it is covered, on the surface thereof, with a resin film containing an organic fluorochemicals via a resin film containing a triazine ring-containing compound or containing an organic fluorochemicals and a triazine ring-containing compound, and that said fiber structure has a water repellency level of grade 4 or higher and an oil repellency level of grade 4 or higher after 20 times of washing.

Description

TECHNICAL FIELD[0001]The present invention relates, to a fiber structure having durable water repellency, oil repellency and antifouling properties.BACKGROUND ART[0002]As conventional methods for letting fabrics, etc. formed of synthetic, fibers, natural fibers and mixed fibers thereof have water repellency and oil repellency, many methods are used for treating the fabrics with fluorine-based compounds, silicone-based compounds, etc.[0003]In recent years, consumers' demands for water repellency and oil repellency performance are growing sharply. Especially demands for clothes with excellent washing durability are strong in the field of sporting wear such as windbreakers, golf wear and ski wear, and demands for clothes with antifouling properties, especially food contamination resistance and washing removability of deposited contamination in addition to durable water repellency and oil repellency are growing in the field of ladies' wear such as coats, blouses, slacks and skirts and i...

Benefits of technology

[0024]According to this invention, since each fiber is covered, on the surface thereof, with a fluorine-based water / oil repellent compound layer via a very thin polymerization film, or with a very thin polymerization film containing a fluorine-based water / oil repellent compound, a fiber structure having durable water / oil repellency for washing and durable antifouling properties for washing can be stably supplied.

[0025]The multifunctional fiber structure of this invention can be effectively used especially for sporting wear application uniform wear application, casual wear application, general wear application, bedclothes application, interior application, etc.THE BEST MODES FOR CARRYING OUT THE INVENTION

[0026]The inventors made are intensive study on the aforementioned problems, namely, to provide all the functions of excellent durable water repellency, oil repellency and antifouling properties, and as a result found that said problems c lid be solved all at once by covering each single fiber, on the surface thereof; with a resin film containing an organic fluorochemicals is a resin film containing triazine ring-containing compound in layers, or by covering each single fiber, our the surface thereof, with a resin film containing an organic fluorochemicals and a triazine ring-containing compound.

[0027]The fiber materials used for the fiber structure of this invention include synthetic fibers such as polyethylene terephthalate, polypropylene phthalate, polybutylene terephthalate, etc., aromatic polyester-based fibers obtained by copolymerizing the foregoing with an other ingredient, aliphatic polyester-based fibers typified by those with L-lactic acid as a main component, polyamide-based fibers such as nylon 6 and nylon 66, acrylic fibers with polyacrylonitrile as a main component, polyolefin-based hers such as polyethylene and polypropylene and polyvinyl chloride-based fibers, semi-synthetic fibers such as acetate and rayon, natural fibers such as cotton, silk and wool, etc. In this invention, any of these types t fibers can be used alone, or two or wore of them can also be used as a mixture. However, fibers with polyester-based fibers or polyamide-based fibers as a main component can be preferably used.

[0028]Further usable are polyurethane-based elastic yarns, polytrimethylene terephthalate yarns, conjugate yarns typified by a bimetal structure using two or more polytrimethylene terephthalates different in viscosity, polymerization degree, shrinkage performance, etc., conjugate yarns consisting of polymethylene terephthalate and polyethylene terephthalate, etc.

[0029]The fibers used in this invention can be any of various types of fibers including, ordinary flat yarns, and also false twist textured yarns, hard twist yarns. Taslan textured yarns, filament yarns such as thick and thin yarns, combined filament yarns, staple fibers, tow yarns, spun yarns, etc.

Problems solved by technology

However, these methods are insufficient in washing durability and no method additionally assuring antifouling properties has been proposed.

However, on a sandy beach, etc., in the case where a non-water repellent swimsuit or a slightly water repellent swimsuit or the like is worn, if the swimsuit and / or the sand is wet, there arises a problem of appearance, since the sand adheres to the swimsuit.

Further, some sand not only temporarily adheres, but also penetrates into the clearances of the texture of the woven or knitted fabric, to raise such a problem that even if the fabric is washed, the sand cannot be removed.

However, no proposal has been made with attention paid to this problem.
