Abstract
An aqueous emulsion composition containing an aminopolysiloxane, a water-soluble oxidant such as hydrogen peroxide and its salts, water and optionally a hydroxy-terminated polysiloxane, which emulsion imparts slickness and durability to a fibrous substrate without releasing volatile organic compounds and method of use is provided.
Claims7
An aqueous emulsion composition comprising:
- (a) an aminopolysiloxane having an amine content ranging from about 0.05% to 3.0% by weight, present at 0.1 to 60 parts per hundred of the total emulsion and having the formula R.sub.3 SiO(R.sub.2 SiO).sub.a (RQSiO).sub.b SiR.sub.3 wherein:
- each R is the same or different and is a hydroxyl or a monovalent hydrocarbon group having 1 to 10 carbon atoms;
- a is from 1 to 5000;
- b is a number from 1 to 100;
- Q has the formula:
- --(X).sub.d (X').sub.e (Y).sub.f-- N(R.sup.1)(R.sup.2), wherein X is a linear or branched alkylene group having 1 to 8 carbon atoms;
- X' is a divalent organic radical;
- Y is selected from the group consisting of a hydroxyl-substituted acyclic alkylene group 2 to 8 carbon atoms and a hydroxyl-substituted cyclic alkylene group having up to 8 carbon atoms;
- d, e and f are zero or one provided the sum of d+e is one and the of sum e+f is zero or two;
- and R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen, an alkyl group having 1 to 8 carbon atoms, a hydroxyalkyl group having 2 to 4 atoms, and an alkyleneamino group having the formula:
- --C.sub.g H.sub.2g N(R.sup.3)(R.sup.4), wherein R.sup.3 and R.sup.4 are independently either hydrogen or an alkyl group having 1 to 8 carbon atoms and g is an integer from 2 to 8;
- (b) a water soluble oxidant present at 0.05 to 5 parts per hundred of the total emulsion;
- and
- (c) water.
