Patent ID: 7851390

Claim:
A planar textile material in the form of a textile fabric with a plurality of yarn systems forming the planar textile material, the planar textile material in the form of the textile fabric comprising a plurality of weft threads and a plurality of warp threads, wherein the planar textile material comprises: 1 to 60 wt % , relative to the planar textile material, of at least one heat-shrinkable plastic yarn, the heat shrinkable plastic yarn having a titer of 100 to 3,000 dtex, a tenacity of 10 to 120 cN/tex, at a temperature of 10 to 100 degrees C., a heat-shrinkage of 5 to 50%, relative to the length of the plastic yarn in the non-shrunk state and at a temperature of 140 to 240 degrees C., a shrinkage force of 100 to 1,000 cN, at a temperature of 140 to 240 degrees C., a shrinkage tension of 0.5 to 10 cN/tex, at a temperature of 140 to 240 degrees C.; and wherein the planar textile material further comprises at least 5 wt%, relative to the planar textile material, of an elastomeric or rubber portion in the form of elastomeric or rubber threads, yarns, or filaments.
