Abstract
The present invention relates to water-free preparations and their use as a sewing yarn finish which comprise (1) 70-98% by weight of a polydialkylsiloxane, (2) 1-29% by weight of a paraffin wax, (3) 0-6% by weight of a fatty acid having 8-22 carbon atoms, (4) 0-6% by weight of a fatty acid ester having 8-22 carbon atoms in the fatty acid radical and 3-22 carbon atoms in the fatty alcohol radical and also (5) 1-5% by weight of a mediator.
Claims4
A water-free preparation comprising, based on total composition:
- 3 (1) 70-98% by weight of a polydialkylsiloxane having trimethylsilyl and/or hydroxyl end groups and a viscosity of 50-10 000 mPa · s;
- (2) 1-29% by weight of a paraffin wax;
- (3) 0-6% by weight of a fatty acid having 8-22 carbon atoms;
- (4) 0-6% by weight of a fatty acid ester having 8-22 carbon atoms in a fatty acid radical and 3-22 carbon atoms in a fatty alcohol radical;
- and (5) 1-5% by weight of a mediator having a formula:
- 4
- or a formula (II)
- 5
- where n and m are integers, n in the formula (I) and a sum total of n and m in the formula (II) are between 2 and 50, a ratio of n:m in the formula (II) is between 1:1 and 49:1 and a radical R1 is one of
- 6
