PRODUCTION OF SOFT YARNS

摘要

This invention relates to a process for the preparation of synthetic fibres for yarns, in which a polymer mass is melted under pressure and then forced through a spinning block to form fibres, and in which the fibre bundle thus obtained is cooled, wherein a slip agent and a softening polymer are added to the molten polymer stream, so that the hand of the synthetic fibres are improved. The invention also relates to the synthetic fibres for yarns, made in this way. The invention further relates to the use of a slip agent in combination with a softening polymer in the production of synthetic yarns for carpets as a means for improving the softness of the produced synthetic fibres.
