Abstract:
The invention relates to a thermally bound non-woven material containing a low-shrinkage dual-component core-sheath fiber consisting of a crystalline polyester core and a crystalline polyester sheath which has a melting point at least 10° C. lower than the core, the heat-shrinkage characteristic of said fiber being less than 10% at 170° C.
