Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
In combination, an ironer roll and a cover cloth fabric wound thereabout, said cover cloth fabric comprising: a plurality of staple fiber spun synthetic yarns; and 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 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 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.
Claim 2
Dependent Claim
116 words
In combination, an ironer roll and a cover cloth fabric wound thereabout, said cover cloth fabric comprising: a plurality of staple fiber spun synthetic yarns; and 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 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 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.
Claim 3
Dependent Claim
48 words
The combination as recited in claim 1, further comprising 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 4
Dependent Claim
23 words
The combination as recited in claim 2, wherein said synthetic yarns include fibers selected from the group consisting of polyester and polyamide fibers.
Claim 5
Dependent Claim
45 words
The combination as recited in claim 3, wherein the work engaging surface of said fabric 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 6
Dependent Claim
36 words
The combination as recited in claim 4, wherein the work engaging surface of said fabric comprises said synthetic yarns having a surface area which is preferably about 3 times the surface area of said glass yarns.
Claim 7
Dependent Claim
28 words
The combination as recited in claim 4, wherein said synthetic yarns have a twist multiplier which is preferably in the range of from about 1.5 to about 2.5.
Claim 8
Dependent Claim
20 words
The combination as recited in claim 6, wherein said synthetic yarns have a twist multiplier which is preferably about 2.
Claim 9
Dependent Claim
20 words
The combination as recited in claim 3, wherein said individually pre-coated glass yarns comprise a plurality of continuous filament fibers.
Claim 10
Dependent Claim
20 words
The combination as recited in claim 3, wherein each one of said synthetic yarns are made from two ply yarn.
Claim 11
Dependent Claim
23 words
The combination as recited in claim 3, wherein said synthetic yarns are interwoven with said individually pre-coated glass yarns in a floating weave.
Claim 12
Dependent Claim
37 words
The combination 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 13
Dependent Claim
19 words
The combination as recited in claim 1 wherein the resin pre-coating said individual glass yarns is resorcinol formaldehyde latex.
