Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
An improved fabric adapted to be manufactured into a cover cloth for use upon flatwork ironer rolls, comprising: a plurality of staple fiber spun synthetic yarns each of which is uncoated, selected from the group consisting of polyester and polyamide fibers a plurality of glass yarns, each of said plurality of glass yarns being individually pre-coated with a resin, said plurality of pre-coated glass yarns being interwoven with said uncoated synthetic yarns so that the major portion of the back surface of the fabric is formed of said pre-coated glass yarns and the major portion of the work engaging surface of the fabric is formed of said uncoated synthetic yarns to thereby impart a controlled smoothness to the work engaging surface thereof which does not impress its weave upon an article being ironed: and a resin coating applied substantially uniformly on substantially the entire back surface of the woven fabric so as to improve the wear and distortion resistance of the fabric by locking said synthetic yarns and said glass yarns in place.
Claim 2
Dependent Claim
173 words

Claim 3
Dependent Claim
43 words
A fabric as recited in claim 1, wherein the work engaging surface thereof comprises said synthetic yarns having a surface area which is preferably in the range of from about 1.5 times to about 4.5 times the surface area of said glass yarns.
Claim 4
Dependent Claim
34 words
A fabric as recited in claim 2, wherein the work engaging surface thereof comprises said synthetic yarns having a surface area which is preferably about 3 times the surface area of said glass yarns.
Claim 5
Dependent Claim
28 words
A fabric as recited in claim 2, wherein said synthetic yarns have a twist multiplier which is preferably in the range of from about 1.5 to about 2.5.
Claim 6
Dependent Claim
20 words
A fabric as recited in claim 4, wherein said synthetic yarns have a twist multiplier which is preferably about 2.
Claim 7
Dependent Claim
20 words
A fabric as recited in claim 1, wherein said individually pre-coated glass yarns comprise a plurality of continuous filament fibers.
Claim 8
Dependent Claim
20 words
A fabric as recited in claim 1, wherein each one of said synthetic yarns are made from two ply yarn.
Claim 9
Dependent Claim
23 words
A fabric as recited in claim 1, wherein said synthetic yarns are interwoven with said individually pre-coated glass yarns in a floating weave.
Claim 10
Dependent Claim
37 words
A fabric as recited in claim 1 wherein the staple fiber spun synthetic yarns constitute the warps of said fabric and the individually pre-coated glass yarns are continuous filament yarns and constitute the picks of said fabric.
Claim 11
Dependent Claim
19 words
A fabric as recited in claim 1 wherein the resin pre-coating said individual glass yarns is resorcinol formaldehyde latex.
