Combinations of filaments having substantially different melting or decomposition points, and use thereof.

摘要

The invention relates to combinations which comprise filaments having different melting or decomposition points and which are constructed preferably in the form of yarns, woven fabrics, knitted fabrics and/or nonwovens, the high-melting filaments generally being present in greater amounts that the low-melting filaments. By heating these combinations to a temperature above the melting or decomposition points of the low-melting filaments and a temperature below the melting or decomposition points of the high-melting filaments, with or without molding, it is possible to produce in a simple manner composite materials in which the high-melting filaments acting as reinforcing elements are present in accurately predeterminable configurations.
