COMBINATIONS OF POLYMER FILAMENTS OR YARNS HAVING A LOW COEFFICIENT OF FRICTION AND FILAMENTS OR YARNS HAVING A HIGH COEFFICIENT OF FRICTION, AND USE THEREOF

摘要

The invention relates to combinations of polymer filaments or yarns of high tensile strength, high modulus and low coefficients of friction and filaments or yarns of high coefficients of friction. Combinations of this type, which have been produced in particular by core spinning the filaments or yarns of low coefficient of friction with filaments or yarns of high coefficients of friction or by twisting the two filament or yarn components, are suitable in particular for producing bulletproof wovens, knits and nonwovens.
