Abstract
A tissue product having improved hand feel and good wettability is produced by printing onto one or both sides of the tissue an aqueous emusilion containing a hydrophilically-modified amino-functional polydimethylsiloxane. The hydrophilically-modified amino-functional polydimethylsiloxane structure has one or more pendant groups containing a terminal amine functionality and at least one pendant group containing an ethylene oxide moiety.
Claims23
A tissue having a Wet Out Time of about 10 seconds or less and containing at least about 2 dry weight percent of a hydrophilically-modified amino-functional polydiorganosiloxane having the following structure:
- wherein:
- X is hydrogen, hydroxy, amino, C1-C8 straight chain, branched, cyclic, unsubstituted or hydrophilically substituted alkyl or alkoxyl radical;
- m=20-100,000;
- p=1-5000;
- q=0-5000;
- R1=a C1-C8, straight chain, branched or cyclic alkyl radical;
- R2=a C1-C10 straight chain or branched, substituted or unsubstituted alkylene diradical;
- wherein
- R5 is an unsubstituted or a hydrophilically substituted C1-C10 alkylene diradical;
- r=1-10,000;
- s=0-10,000;
- and
- Z=hydrogen, C1-C24 alkyl group, or a G-group, where G is selected from the following:
- —R5COOR7;
- —CONR8R9;
- —SO3R8;
- and POR8R9, where R6 is a substituted or unsubstituted C1-C8 alkylene diradical;
- R7, R8, and R9 are independently a hydrogen radical or a substituted or unsubstituted C1-C8 alkyl radical;
- and
- wherein
- R10, R11, and R12 are independently an unsubstituted or a hydrophilically substituted C1-C8 alkylene diradical;
- t=0-10,000, such that if “t”=0, then “q” is at least 1;
- u=0-10,000;
- w=0-10,000;
- and
- R13, R14 and R15 are independently a hydrogen radical, an unsubstituted or a hydroxyl, carboxyl or other functionally substituted C1-C10 straight chain, branched, or cyclic alkyl radical.
