PROCESS FOR THE PREPARATION OF SYNTHETIC FIBRES FOR YARNS WITH INCREASED DYEABILITY

摘要

This invention relates to a process for the preparation of polyolefin based 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 prior to extrusion a mixture of PET (polyethylene terephthalate) or co - polyester and SEBS (styrene ethylene butylenes copolymer) is added to the molten polymer stream, so that the dyeability of the synthet ic fibres is improved. The invention also relates to the synthetic fibres for yarns, made in this way. This invention further relates to a rug or carpet comprising such a synthetic fibres.
