Staple fiber yarn, textile fabric comprising the staple fiber yarn and articles comprising the textile fabric

Abstract

A staple fiber yarn is presented, which comprises a staple fiber blend that contains staple fibers A and staple fibers B, whereby the staple fibers A as well as the staple fibers B consist of polymers that are selected from the groups of aramids, polyolefins, polybenzoxazoles and polybenzthiazoles, the staple fibers A having a linear density T(A) and the staple fibers B having a linear density T(B) and the linear density ratio T(B):T(A) lying in the range from 1.5:1 to 8.8:1. In addition, a textile fabric comprising the staple fiber yarn and articles comprising the textile fabric are presented.
