Abstract
The present invention relates to a process for producing thermoplastic fibres having reduced surface tension and also to products obtainable by the melt-spinning process from these thermoplastic fibres having reduced surface tension, wherein the thermoplastic to be used is admixed with a copolymer of at least one α-olefin and at least one acrylic or methacrylic ester of an aliphatic alcohol.
Claims14
Process for reducing the surface tension of thermoplastic-based fibres or filaments, the process comprising:
- introducing into the thermoplastic at least one E/X copolymer of an α-olefin and an acrylic or methacrylic ester of an unsubstituted aliphatic alcohol having 6 to 30 carbon atoms to produce a thermoplastic-copolymer mixture, wherein the thermoplastic is polyamide or polyester;
- and
- melt-spinning the thermoplastic-copolymer mixture into fibres or filaments.
Reducing the surface tension of thermoplastic fibres or thermoplastic filaments by mixing into the thermoplastic at least one E/X copolymer of an α-olefin and an acrylic or methacrylic ester.
