Abstract
Abstract There is disclosed a process which comprises the steps of: (a) bonding a web of fusible staple fibers by thermal bonding in an intermittent pattern; (b) stretching the bonded web at elevated temperature; and (c) cooling the stretched web, to thereby produce a fabric having elastic properties perpendicular to the direction of stretch.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
45 words
1 . Process which comprises stretching, at elevated temperature, a thermally bonded web wherein the thermal bonds are in an intermittent pattern, and then cooling the stretched web, to thereby produce a fabric having elastic properties in the direction perpendicular to the direction of stretch.
Claim 2
Dependent Claim
45 words
1 . Process which comprises stretching, at elevated temperature, a thermally bonded web wherein the thermal bonds are in an intermittent pattern, and then cooling the stretched web, to thereby produce a fabric having elastic properties in the direction perpendicular to the direction of stretch.
Claim 3
Dependent Claim
52 words
Process which comprises the steps of: (a) bonding a web of fusible staple fibres by thermal bonding in an intermittent pattern; (b) stretching the bonded web at elevated temperature; and (c) cooling the stretched web, to thereby produce a fabric having elastic properties in the direction perpendicular to the direction of stretch.
Claim 4
Dependent Claim
52 words
Process which comprises the steps of: (a) bonding a web of fusible staple fibres by thermal bonding in an intermittent pattern; (b) stretching the bonded web at elevated temperature; and (c) cooling the stretched web, to thereby produce a fabric having elastic properties in the direction perpendicular to the direction of stretch.
