Fabric having a foamed layer and a method for producing thereof

Abstract

It is prepared to be an elastic net which is elastic in the cross machine direction and non-elastic in the machine direction. A combined sheet is obtained by joining the net and a filamentous web. The filamentous web comprises of drawn thermoplastic continuous filaments which are oriented in a machine direction. A laminated web is obtained by laying a fibrous web of staple fibers on the combined sheet. A high-pressure liquid flow is applied to the laminated web. The staple fibers are entangled among, and with the net. A method for producing a pressure-sensitive adhesive tape or sheet.
