摘要
The invention relates to a method for producing a spunbonded fabric from thermobonded crimped bicomponent fibers. The bicomponent fibers each consist of two plastic materials with different properties. The inventive method comprises three steps: in the first step, the uncrimped fibers spun from the two plastic materials are detached and drawn. In the second step, the fibers are placed on a perforated belt and thermobonded. In the third step, the bicomponent fibers of the spunbonded fabric obtained are crimped by longitudinal and/or transversal stretching and heat treatment.
