Abstract

PROBLEM TO BE SOLVED: To obtain a finished fabric which has a wind-breaking property, a water pressure-resistant property, a moisture-permeating property, and the like and is lightweight when worn, by forming a urethane resin layer containing metal titanium particles on at least one surface of a base fabric. SOLUTION: This processed fabric is obtained by imparting a metal titanium particle-dispersed urethane resin coating to at least one surface of a base fabric to form the urethane resin layer. The base fabric includes the woven or knitted fabric of polyester fibers, wool or silk, preferably a polyester taffeta which is dyed into a prescribed color tone and further calendered. The metal titanium particle-dispersed urethane resin coating is preferably obtained by dispersing 5 to 300 pts.wt. of metal titanium particles having an average particle diameter of 5 to 300 μm in 100 pts.wt. of a urethane resin, such as a polyether-based polyurethane, when the coating method is a dry coating method, or a polyester- based polyurethane, when the coating method is a wet coating method. It is preferable that a water-repelling processing treatment using a fluororesin is applied to at least one surface of either of the above processed fabric and the base fabric before the urethane resin layer is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work cloth for clothing that has windproofness, water pressure resistance, moisture permeability, is lightweight when worn, and gives a warm feeling that adapts to body temperature quickly, and a method of manufacturing the same.

[0002]

[Prior art and problems to be solved]
Fabrics and knits of fibers with ceramics added; Fabrics and knits of acrylic fibers using the heat of hydration; furthermore, fabrics and knits with ceramic print, but also windproof, water-resistant and moisture-permeable In addition, there was no known work cloth having improved performance.

[0003]

The inventors of the present invention disperse and hold metallic titanium particles in a polyurethane resin paint (coating material) used for coating a base fabric, and the finished work cloth is made of the above-mentioned prior art. Has found that it brings improvements that could not be reached.

That is, in producing a work cloth having a polyurethane resin layer provided on at least one surface of a base cloth by a wet method or a dry method, it is essential for the invention to disperse metal titanium particles in the resin layer. Is what you do. To explain in more detail, polyester, nylon, cotton,
Hemp, rayon, wool, silk and other woven or knitted fabrics can be used. When high wind resistance is required, a high-density taffeta with a large number of strikes between inches is preferred.

[0005] As the polyurethane resin, polyester-based urethane resins, polyether-based urethane resins, polycarbonate-based urethane resins, and mixtures thereof are used. When a wet method is used as the film forming method, a polyester-based urethane resin is preferable, and high moisture permeability can be obtained. On the other hand, in the dry method, a polyether-based urethane resin is preferable, and high moisture permeability can be obtained. In the case of the dry method, it is effective to provide an adhesive layer on the base cloth in advance, and for this purpose, a two-pack reaction type urethane resin is suitable.

[0006] As the metal titanium particles, those manufactured and marketed for powder metallurgy can be used.
３００300 μm can be used. Among them, those having an average particle size of about 50 μm are easy to handle, and are suitable in terms of processability and performance. When the average particle size is 5 μm or less, there is a disadvantage that a dust explosion easily occurs. When the average particle size is 300 μm or more, exfoliation of the metal titanium particles easily occurs. Exfoliation of the titanium metal particles leads to a decrease in water pressure resistance. The mixing amount of the metal titanium particles can be experimentally determined depending on the purpose in the range of about 5 to 300 parts with respect to 100 parts by weight of the urethane resin.

The water-repellent treatment may be applied to the base cloth before the urethane resin is applied, or may be applied to the finished work cloth. As the water repellent, an ordinary fluorine-based water repellent can be applied.

[0008]

The work cloth of the present invention has the properties of heat storage, wind resistance, water pressure resistance, moisture permeability and light weight (the specific gravity of titanium metal is as low as 4.5), and is suitable for outdoor rainwear. , Dustproof clothing, windbreakers, inner materials, gloves, shoes, etc. are promising applications. Hereinafter, the present invention will be described with reference to examples.
