Fluorosilicone compositions as wash durable soil and stain repellent finishes

A method for imparting wash durable soil and stain repellency to a fibrous substrate, which method comprises contacting a fibrous substrate with durable press resin, a catalyst, and a perfluoroalkyl hydroxyalkyl siloxane selected from the group consisting of

• (i) linear siloxanes having the general formula:
• ##STR6## wherein a=0 to 100;
• b=1 to 100;
• c=1 to 100;
• and
• (ii) cyclic siloxanes having the general formula:
• ##STR7## wherein d=0 to 10;
• e=1 to 10;
• f=1 to 10
• with the proviso that d+e+f is greater than or equal to 3;
• and wherein in the formulae
• each R.sup.1 and R.sup.2 is selected from the group consisting of hydrogen, hydroxy, and an alkyl group having 1 to 6 carbon atoms;
• R.sup.3 is selected from the group consisting of (CH.sub.2).sub.y CHOHCHR.sup.2 and (CH.sub.2).sub.g Q.sub.j, wherein Q is selected from the group consisting of --NH--, --S--, and --O--;
• i is 0 or 1;
• y is 2 to 4;
• and g is 1 to 6;
• R.sup.4 is selected from the group consisting of CH.sub.3, (CH.sub.2).sub.m CHR.sup.1 (CH.sub.2).sub.n O.sub.h (CH.sub.2).sub.i CHR.sup.2 (CH.sub.2).sub.r OH, and R.sup.3 ZR.sup.F ;
• Z is selected from the group consisting of --NHCO--, --NHSO.sub.2 --, --O.sub.2 C--, --O.sub.3 S--, --OCH.sub.2 CH.sub.2 --, --NHCH.sub.2 CH.sub.2 --, and --CH.sub.2 CHOHCH.sub.2 --;
• m is 1 to 6;
• n is 0 to 6;
• R.sup.F is a perfluoro alkyl group, C.sub.p F.sub.2p+1, wherein p is 1 to 20;
• h is 0 or 1;
• i is 0 to 6;
• r is 0 to 4;
• and
• each R.sup.5 is independently selected from the group consisting of methyl group, ethyl group, and a phenyl group.
