Abstract
A staple fiber yarn having at least one twisted thread. The twisted thread includes a mixture of first staple fibers and second staple fibers. The first staple fibers are produced from high-strength filaments and the second staple fibers have a shrinkage in the range from 5% to 50%. The weight ratio of the first to second staple fibers lies in the range of 5:95 to 45:55. A method for producing a textile article wherein shrinkage is implemented either on the staple fiber yarn, after which the article is produced from the shrunken staple fiber yarn, or on the article containing the non-shrunken staple fiber yarn. The textile article has a wear resistance that is similarly high or indeed even higher than that of a correspondingly produced textile article, the staple fiber yarn of which consists exclusively of first staple fibers that are produced from high-strength filaments.
