Abstract
A fiber treating agent which is a silicone modified polyester in which a polyester has a polyoganosiloxane grafted thereto. The grafted polyester is the reaction product of an allyl ether containing polyester and a polyorganosiloxane wherein at least one of the silicon atoms of the polyorganosiloxane has a hydrogen atom attached thereto. Preferably, the hydrogen atom is attached to one terminal end of the polyorganosiloxane. The reaction product is modified by reacting the reaction product with a polycarboxylic anhydride, and the amine salt of the modified reaction product may be formed by reacting the modified reaction product with an aminoalkylalkoxysilane. Methods of treating fibrous materials are also described.
Claims9
A method of treating fibrous material comprising depositing on the fibrous material 0.01 to 5.0 percent by weight based on the weight of the fibrous material of a fiber treating agent comprising a silicone modified polyester in which a polyester has a polyorganosiloxane grafted thereto, the grafted polyester being the reaction product of an allyl ether containing polyester and a polyorganosiloxane wherein at least one of the silicon atoms of the polyorganosiloxane has a hydrogen atom attached thereto;
- the allyl ether containing polyester being formed by combining a polycarboxylic acid and a polyhydric alcohol;
- the polycarboxylic acid being selected from the group consisting of adipic acid, phthalic anhydride, isophthalic acid, and terephthalic acid;
- the polyhydric alcohol being selected from the group consisting of ethylene glycol, neopentyl glycol, trimethylolpropane, trimethylolethane, trimethylolpropane monoallyl ether, trimethylolethane monoallyl ether, glycerol, glycerol monoallyl ether, pentaerythritol, pentaerythritol monoallyl ether, and pentaerythritol diallyl ether.
