Described herein are nonfluorinated polyurethanes having (a) a plurality of silicon polyol units and (b) a plurality of organic polyol units, wherein at least one of the organic polyol units has an ionizable group. The polyurethanes can be applied to a variety of different articles. The polyurethanes can impart a number of beneficial properties to an article including, but not limited to, liquid repellency, stain resistance, and bleach resistance. The nonfluorinated polyurethanes described herein are as effective or perform substantially better than fluorinated compounds currently used in the market. Methods for making the nonfluorinated polyurethanes are also described herein.

Nonfluorinated polyurethanes and methods of making and using thereof

Described herein are nonfluorinated polyurethanes having (a) a plurality of silicon polyol units and (b) a plurality of organic polyol units, wherein at least one of the organic polyol units has an ionizable group, and wherein the nonfluorinated polyurethanes are terminated by amino groups. The polyurethanes can be applied to a variety of different articles. The polyurethanes can impart a number of beneficial properties to an article including, but not limited to, liquid repellency, stain resistance, and bleach resistance. The nonfluorinated polyurethanes described herein are as effective or perform substantially better than fluorinated compounds currently used in the market. Methods for making the nonfluorinated polyurethanes are also described herein.

The invention relates to a process for increasing the dyeability of textile fibers and fabrics without the need to use a salt in the dyebath. The dyeing is performed on fibers or fabrics which have been treated with sodium hydroxide and an epoxy ammonium salt of the formula: ##STR1## wherein R,R',R', and R'' are alkyl radicals having 1 to 8 carbon atoms, and X.sup.- is an anionic group selected from the group consisting of sulfate, sulfonate and halide.

Method for salt-free dyeing

The invention relates to a process for increasing the dyeability of textile fibers and fabrics without the need to use a salt in the dyebath. The dyeing is performed on fibers or fabrics which have been treated with potassium hydroxide and an epoxy ammonium salt of the formula: ##STR1## wherein R, R', R', and R'' are alkyl radicals having 1 to 8 carbon atoms, and X.sup.- is an anionic group selected from the group consisting of sulfate, sulfonate and halide.
