Abstract
Abstract An improved method is provided for treating and processing textile materials which comprises contacting said textile materials with an aqueous composition containing a low-foaming, nonionic surfactive agent having a block-random structure represented by the formula: R-O-Ax-B-H where R is a primary alkyl group having from 7 to 11 carbon atoms; A is oxypropylene groups; x is an integer of from 3 to about 15 and B is a random mixture of oxyethylene and oxypropylene groups having a molar ratio of oxyethylene to oxypropylene of from about 2:1 to about 5:1.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A method of treating and processing textile fibers and fabrics which comprise contacting said textile materials with an aqueous composition comprising at least about 0.01 percent by weight of a low-foaming, nonionic surface active agent having a block-random structure represented by the formula: R--O--A.sub.x --B--H wherein R is a primary alkyl group having from 7 to 11 carbon atoms, A is oxypropylene groups, x is an integer of from 3 to about 15 with the proviso that the sum of number of carbon atoms in the alkyl group and of 1/3 of value of x is in the range from 10 to about 12, and B is a random mixture of oxyethylene and oxypropylene groups in the molar ratio of oxyethylene to oxypropylene of from about 2:1 to about 5:1 with the total amount of said random mixture of oxyalkylene groups being such that the surface active agent is a liquid having a cloud point in the range from about 20° C. to about 60° C.
Claim 2
Independent Claim
166 words
A method of treating and processing textile fibers and fabrics which comprise contacting said textile materials with an aqueous composition comprising at least about 0.01 percent by weight of a low-foaming, nonionic surface active agent having a block-random structure represented by the formula: R--O--A.sub.x --B--H wherein R is a primary alkyl group having from 7 to 11 carbon atoms, A is oxypropylene groups, x is an integer of from 3 to about 15 with the proviso that the sum of number of carbon atoms in the alkyl group and of 1/3 of value of x is in the range from 10 to about 12, and B is a random mixture of oxyethylene and oxypropylene groups in the molar ratio of oxyethylene to oxypropylene of from about 2:1 to about 5:1 with the total amount of said random mixture of oxyalkylene groups being such that the surface active agent is a liquid having a cloud point in the range from about 20° C. to about 60° C.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein R is a primary alkyl group having from 8 to 10 carbon atoms.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein said aqueous composition comprises up to about 12 percent by weight of said surface active agent.
Claim 5
Dependent Claim
22 words
The method of claim 1 wherein the textile treating composition contains from 0.01 to 2 weight percent of said surface active agent.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein R--O represents the residue of 2-ethylhexanol.
Claim 7
Dependent Claim
16 words
The method of claim 1 which is a process for washing or scouring a textile material.
Claim 8
Dependent Claim
14 words
The material of claim 1 which is a process for "wetting-out" a textile material.
