Abstract
The disclosure is of an improved high temperature resistant open mesh fabric and its use in a method for drying textiles.
Claims5
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).

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.
