Title:
COMPOSITE NONWOVEN CLOTH HAVING EXCELLENT PEELING STRENGTH AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH10195747
Kind Code:
A
Abstract:

To provide composite nonwoven cloth having excellent peeling strength.

This nonwoven cloth is composed of a lamination of stretchable continuous fiber nonwoven cloth comprising continuous fiber groups and short fiber nonwoven cloth comprising short fiber groups. The stretchable continuous fiber nonwoven cloth has many heat-fusible regions. The continuous fibers are heat-fused with each other and the continuous fiber groups are fixed in a dense state in the heat-fusible regions and each heat-fused region is arranged at a prescribed interval, then a shape of the nonwoven cloth is maintained. In a region other than the heat-fused region, a property hardly stretchable in the length direction and easily stretchable in the breadth direction is imparted to the stretchable continuous nonwoven cloth by arranging the continuous fiber groups in substantially length direction. A shape of the short fiber nonwoven cloth is maintained by confounding between the short fibers with each other. The stretchable continuous fiber nonwoven cloth are stiffly bonded with the short fiber nonwoven cloth by confounding the short fiber groups with the continuous fiber groups in the laminating face of the stretchable continuous fiber nonwoven cloth and the short fiber nonwoven cloth.
