Abstract
Abstract This invention relates to a fiber product formed by flexible coating, the fiber product being made of a cloth knitted or woven by fiber yarns. Each space between the fiber yarns facing to each other is formed 1.5 to 4 times as large as the thickness of each fiber yarn, and a repelling layer of a preferred resin is coated on the outer overall surface of the fiber yarns, subsequently a thin, expansible and flexible layer of polyvinyl chloride resin being, under no pressure, coated on one outer portion of the fiber yarns by the polyvinyl chloride resin paste. As a result, the repelling layer can prevent the polyvinyl chloride resin paste from penetrating into the space between the facing fiber yarns.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
A fiber product formed by flexible coating, comprising a cloth knitted or woven of fiber yarns, the space between adjacent fiber yarns being 1.5 to 4 times as large as the thickness of each fiber yarn, a repelling layer of resin coated on the outer overall surface of the fiber yarns, and a thin, expansible and flexible layer of polyvinyl chloride resin being coated on at least one outer portion of the fiber yarns with the repelling layer preventing the polyvinyl chloride resin from substantially penetrating into the space between the facing fiber yarns during the coating thereof.
Claim 2
Dependent Claim
98 words
A fiber product formed by flexible coating, comprising a cloth knitted or woven of fiber yarns, the space between adjacent fiber yarns being 1.5 to 4 times as large as the thickness of each fiber yarn, a repelling layer of resin coated on the outer overall surface of the fiber yarns, and a thin, expansible and flexible layer of polyvinyl chloride resin being coated on at least one outer portion of the fiber yarns with the repelling layer preventing the polyvinyl chloride resin from substantially penetrating into the space between the facing fiber yarns during the coating thereof.
Claim 3
Dependent Claim
21 words
A fiber product claimed in claim 1, wherein the repelling layer is made of fluorine resins, silicon resin or the like.
Claim 4
Dependent Claim
20 words
A fiber product claimed in claim 1, in the form of a work glove, a diaper cover, or a sheet.
Claim 5
Dependent Claim
45 words
A fiber product claimed in claim 1, produced by a process wherein the consumption of the fiber yarns and of the polyvinyl chloride resin involved is modified by widening the space between the facing fiber yarns and thinning the layer of the polyvinyl chloride resin.
Claim 6
Independent Claim
93 words
A method of forming a flexible coated fiber product comprising: (a) knitting or weaving a cloth of fiber yarn having spaces between adjacent fibers of from about 1.5 to about 4 times the thickness of said fiber yarn; (b) coating a repelling layer on the outer overall surface of the fiber yarn in said cloth; and (c) coating at least one surface of said fiber yarn under no pressure with a thin expansible polyvinyl chloride resin paste whereby the repelling layer prevents the polyvinyl chloride resin paste from penetrating substantially into said spaces.
Claim 7
Independent Claim
93 words
A method of forming a flexible coated fiber product comprising: (a) knitting or weaving a cloth of fiber yarn having spaces between adjacent fibers of from about 1.5 to about 4 times the thickness of said fiber yarn; (b) coating a repelling layer on the outer overall surface of the fiber yarn in said cloth; and (c) coating at least one surface of said fiber yarn under no pressure with a thin expansible polyvinyl chloride resin paste whereby the repelling layer prevents the polyvinyl chloride resin paste from penetrating substantially into said spaces.
