Abstract
Abstract A textile finishing composition comprising (1) a diluent and (2) a durable press resin composition containing (a) an aminoplast resin and (b) an aldehyde. The textile finishing composition is combined with an acid catalyst and applied to textile materials to impart softness, improved wetting properties and durable press properties. The textile finishing composition is applied at lower than normal dry add-on levels to textile materials to provide textile materials having lower levels of formaldehyde.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
76 words
A textile finishing composition comprising (1) a diluent and (2) a durable press resin composition containing (a) an aminoplast resin and (b) an aldehyde in excess of that present in the aminoplast resin in which the durable press resin composition is present in an amount of at least 0.18 percent by weight based on the weight of the diluent and aminoplast resin and the weight ratio of aldehyde to aminoplast resin is from 0.05 to 0.6.
Claim 2
Dependent Claim
76 words
A textile finishing composition comprising (1) a diluent and (2) a durable press resin composition containing (a) an aminoplast resin and (b) an aldehyde in excess of that present in the aminoplast resin in which the durable press resin composition is present in an amount of at least 0.18 percent by weight based on the weight of the diluent and aminoplast resin and the weight ratio of aldehyde to aminoplast resin is from 0.05 to 0.6.
Claim 3
Dependent Claim
13 words
The composition of claim 1, wherein the composition contains (3) a softening agent.
Claim 4
Dependent Claim
39 words
The textile finishing composition of claim 1, wherein the durable press resin composition is present in an amount of from 0.18 to 72 percent by weight, based on the weight of the diluent and the durable press resin composition.
Claim 5
Dependent Claim
17 words
The composition of claim 3, wherein a softening agent is present in the durable press resin composition.
Claim 6
Dependent Claim
13 words
The composition of claim 2, wherein the softening agent is a crosslinkable organopolysiloxane.
Claim 7
Dependent Claim
103 words
The composition of claim 5, wherein the crosslinkable orgnopolysiloxane contains an organopolysiloxane of the formula ##STR22## and a crosslinking agent selected from the group consisting of silanes of the formula ##STR23## and siloxanes having Si--O--Si linkages wherein the unsatisfied valences of the silicon atoms are satisfied by R 9 and Y, where R 9 is a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, Y is a hydrolyzable group, b is from 1 to 1000, m is 0 or 1 and when the crosslinking agent is a siloxane then an average of at least 3 hydrolyzable groups are present per molecule.
Claim 8
Dependent Claim
38 words
