Textile fabric material with shrinkage properties and its use

A textile sheet structure in the form of a textile fabric with heat-shrinkage properties and elastic properties,

• wherein the textile sheet structure comprises or consists of a yarn system comprising a plurality of weft yarns and a plurality of warp yarns;
• wherein the yarn system comprises or consists of at least one heat-shrinkable elastic plastic yarn which retains its elastic properties at least partially even after heat-shrinkage treatment, wherein the heat-shrinkable elastic plastic yarn after heat-shrinkage treatment has a residual elasticity in the range of from 50% to 99%, relative to the elasticity of the heat-shrinkable elastic plastic yarn in the unshrunk state,
• wherein the heat-shrinkable elastic plastic yarn is based on one heat-shrinkable elastomeric and thermoplastic polyester,
• wherein the heat-shrinkable elastic plastic yarn has a residual elongation before the heat-shrinkage treatment of less than 30%, determined according to DIN 53 835-3, and wherein the heat-shrinkable elastic plastic yarn has a residual elongation after the heat-shrink treatment of less than 35%, determined according to DIN 53 835-3,
• wherein the heat-shrinkable elastic plastic yarn has an elongation at break of more than 55%, determined according to DIN EN ISO 2062:2010-04;
• wherein the yarn system is free from non-heat-shrinkable elastic plastic yarns and
• wherein the sheet structure is elastic in the weft direction and in the warp direction, wherein the elasticity of the sheet structure in the weft direction and in the warp direction, independently of one another, is in the range from 2% to 25%, determined according to DIN 53 360.
