Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A process for providing a durable press on a cellulosic textile garment or other article which comprises applying to cellulosic textile fabric a finish comprising an aqueous mixture of, on a weight basis, 3-25 percent of a thermosetting durable press textile reactant, 3-20 percent of at least one low temperature crosslinking acrylic polymer, and 0.1-7 percent of a crosslinking catalyst, drying, cutting said fabric into pieces and sewing the same together into said garment or article and pressing the resulting article in the desired shape and simultaneously curing the finish so as to obtain said durable press, the pressing and curing being carried out at a temperature not in excess of about 345*F.
Claim 2
Dependent Claim
113 words
A process for providing a durable press on a cellulosic textile garment or other article which comprises applying to cellulosic textile fabric a finish comprising an aqueous mixture of, on a weight basis, 3-25 percent of a thermosetting durable press textile reactant, 3-20 percent of at least one low temperature crosslinking acrylic polymer, and 0.1-7 percent of a crosslinking catalyst, drying, cutting said fabric into pieces and sewing the same together into said garment or article and pressing the resulting article in the desired shape and simultaneously curing the finish so as to obtain said durable press, the pressing and curing being carried out at a temperature not in excess of about 345*F.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein the cross-linking acrylic polymer comprises the copolymer of a lower alkyl acrylate and methylolated-4-pentenoguanamine.
Claim 4
Dependent Claim
16 words
The process of claim 1 wherein the pressed and cured textile article is subsequently further cured.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
15 words
The process of claim 2 wherein the mixture also includes a film-forming heat curable elastomer.
Claim 9
Dependent Claim
12 words
The process of claim 7 wherein the elastomer is a polyester elastomer.
