Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A fabric which comprises an open mesh of: (a) at least three warpwise elements in each of an array of parallel warp knitted chains extending in the machine-direction, said chains being evenly spaced from each other in intervals of from 2 to 12 per inch of fabric, said elements comprising: (i) a first chain stitch yarn; (ii) a second chain stitch yarn with periodic underlaps connecting adjacent chains; (iii) a first reinforcing lay-in yarn having a linear density of from about 400 to about 1000 denier; and optionally (iv) a second reinforcing lay-in yarn having said linear density; provided that when the yarn (iv) is not present then the linear density of yarn (iii) is doubled; and (b) a plurality of cross machine-direction yarn components, evenly spaced from each other in intervals of from 2 to 12 per inch of fabric and positioned between the warpwise elements (i), (ii) and (iii).
Claim 2
Dependent Claim
151 words
A fabric which comprises an open mesh of: (a) at least three warpwise elements in each of an array of parallel warp knitted chains extending in the machine-direction, said chains being evenly spaced from each other in intervals of from 2 to 12 per inch of fabric, said elements comprising: (i) a first chain stitch yarn; (ii) a second chain stitch yarn with periodic underlaps connecting adjacent chains; (iii) a first reinforcing lay-in yarn having a linear density of from about 400 to about 1000 denier; and optionally (iv) a second reinforcing lay-in yarn having said linear density; provided that when the yarn (iv) is not present then the linear density of yarn (iii) is doubled; and (b) a plurality of cross machine-direction yarn components, evenly spaced from each other in intervals of from 2 to 12 per inch of fabric and positioned between the warpwise elements (i), (ii) and (iii).
Claim 3
Dependent Claim
12 words
The fabric of claim 1 wherein the yarns are high-temperature resistant yarns.
Claim 4
Dependent Claim
14 words
The fabric of claim 2 which is coated with a heat-resistant, synthetic polymeric resin.
Claim 5
Dependent Claim
9 words
An endless belt of the fabric of claim 1.
Claim 6
Dependent Claim
180 words
In a method of drying a textile fabric by supporting the fabric on a conveyor belting and conveying the supported fabric through a drying oven, the improvement which comprises: employing as the conveyor belt an endless fabric, which comprises: an open mesh of: (a) at least three warpwwise elements in each of an array of parallel warp knitted chains extending in the machine-direction, said chains being evenly spaced from each other in intervals of from 2 to 12 per inch of fabric, said elements comprising: (i) a first chain-stitch yarn; (ii) a second chain-stitch yarn with periodic underlaps connecting adjacent chains; (iii) a first reinforcing lay-in yarn having a linear density of from about 400 to about 1000 denier; and optionally (iv) a second reinforcing lay-in yarn having said linear density; provided that when the yarn (iv) is not present then the linear density of yarn (iii) is doubled; and (b) a plurality of cross-machine direction yarn components evenly spaced from each other in intervals of from 2 to 12 per inch of fabric and positioned between the warpwise elements.
Claim 7
