Abstract
A crosslinkable composition comprising (A) an organopolysiloxane which has at least one monovalent SiC-bonded radical containing primary and/or secondary amino groups, and (B) a crosslinking component selected from an alkoxysilane and/or siloxane which contains at least one carboxylic acid anhydride group. The crosslinkable composition and/or the resultant organopolysiloxane compound obtained from the reaction of organopolysiloxane (A) and crosslinking component (B) can be used to treat organic fibers and textile structures produced therefrom.
Claims11
A crosslinkable composition comprising (A) an organopolysiloxane which has at least one siloxane unit of the general formula ##EQU5## and all other siloxane units have the general formula ##EQU6## in which R.sup.1 represents a monovalent C.sub.1 to C.sub.18 hydrocarbon radical or a monovalent C.sub.1 to C.sub.18 hydrocarbon radical which is substituted with a fluorine, chlorine or bromine atom, a hydrogen atom, a C.sub.1 to C.sub.12 alkoxy radical or hydroxyl radical or an alkyl glycol radical, Q represents a group of the general formula
- --R.sup.5 --[NR.sup.2 (CH.sub.2).sub.m ].sub.d NHR.sup.2 (III)
- in which R.sup.5 represents a divalent C.sub.1 to C.sub.18 hydrocarbon radical, R.sup.2 represents a hydrogen atom or a C.sub.1 to C.sub.18 hydrocarbon radical or a C.sub.1 to C.sub.18 hydrocarbon radical substituted with a fluorine, chlorine or bromine atom, a has a value of 0, 1 or 2, b has a value of 1, 2 or 3, c has a value 0, 1, 2 or 3 d has a value of 0, 1, 2, 3 or 4, m has a value of 2, 3, 4, 5 or 6 and the sum of a +b is no more than 4 and (B) an alkoxysilane having at least one carboxylic acid anhydride group as a crosslinking component.
A process for treating organic fibers and textile materials produced therefrom which comprises applying an emulsion prepared by reacting
- (A) an organopolysiloxane having at least one monovalent SiC-bonded radical containing primary and/or secondary amino groups, with
- (B) an alkoxysilane crosslinking component having at least one carboxylic acid anhydride group and
- (C) an acylating agent before, during or after formation of the emulsion;
- to the organic fibers.
