Abstract
Abstract This disclosure relates to a method for imparting durable press characteristics to textile fabrics containing cellulosic fibers. The fabric is impregnated with a homogeneous composition comprising a volatile liquid carrier and certain methoxylated, phenyl-substituted fluid organosilicon polymers, and is subsequently heated to effect crosslinking of the fluid organosilicon polymers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A method for imparting durable press characteristics to a cellulosic fiber containing textile fabric, said method being characterized by sequentially: (a) impregnating the textile fabric with a homogeneous composition comprising a volatile liquid carrier and a fluid organosilicon polymer selected from the group consisting of (i) polymers consisting of units and units wherein x has a value of 2, 1 or 0, y has a value of 1 or 0, the sum of x + v has a value greater than 0, and the molar ratio of units to units has a value of from 1:4 to 1:40 and (ii) polymers consisting of units, units, and units wherein x has a value of 2, 1 or 0, z has a value of 2, 1 or 0, the sum of x + z has a value greater than 0, the molar ratio of units to units has a value from 1:0.5 to 1:4, and the molar ratio of units to units has a value of from 1:0.85 to 1:3.5; and (b) heating the impregnated textile fabric of (a) to crosslink the fluid organosilicon polymer.
Claim 2
Independent Claim
183 words
