摘要
A process is disclosed for the manufacture of a spunbonded fabric consisting of thermobonded curled bicomponent fibers where the bicomponent fibers consist of two plastic materials with different properties. The process according to the invention consists of three steps: the fibers spun from the two plastic materials are drawn off uncurled and stretched in a first step. In a second step the fibers are placed on a sieve belt and thermobonded. In a third step the bicomponent fibers of the obtained nonwoven fabric are finally curled by lengthwise and/or transverse stretching and heat treatment.
