ORGANOPOLYSILOXANE-CONTAINING FIBRE

摘要

The invention relates to a fibre which can be produced from a composition containing an organopolysiloxane/polyurea/polyurethane block copolymer (A) of general formula (1), where R is a monovalent hydrocarbon radical having 1 to 20 carbon atoms which is optionally substituted by fluorine or chlorine, X is an alkylene radical having 1 to 20 carbon atoms, in which methylene units not adjacent to one another may have been replaced by -O- groups, A is an oxygen atom or an amino group -NR`-, Z is an oxygen atom or an amino group -NR`-, R` is hydrogen or an alkyl radical having 1 to 10 carbon atoms, Y is a divalent hydrocarbon radical having 1 to 20 carbon atoms which is optionally substituted by fluorine or chlorine, D is an alkylene radical having 1 to 700 carbon atoms which is optionally substituted by fluorine, chlorine, C₁-C₆ alkyl or C₁-C₆ alkyl ester and in which methylene units not adjacent to one another may have been replaced by -O-, -COO-, -OCO-, or -OCOO- groups, n is a number from 1 to 4000, a is a number which is at least 1, b is a number from 0 to 40, c is a number from 0 to 30 and d is a number greater than 0, and at least one thermoplastic material (B).
