Abstract
Abstract Textile materials containing cellulosic fibers are provided with durable press properties by reacting and crosslinking a silicone compound with the cellulosic fibers. The fabric is impregnated with a finishing bath containing the silicone compound and a suitable catalyst and the fabric is heated to dry and cure and crosslink the finishing composition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
63 words
A process of treating textile materials containing cellulosic fibers to provide durable press properties, said process comprising impregnating the material with a durable press finishing agent consisting essentially of a siloxane compound, drying the impregnated material, and irradiating the material with actinic radiation to react and crosslink the siloxane compound with the cellulosic fibers to impart said durable press properties to the fabric.
Claim 2
Dependent Claim
63 words
A process of treating textile materials containing cellulosic fibers to provide durable press properties, said process comprising impregnating the material with a durable press finishing agent consisting essentially of a siloxane compound, drying the impregnated material, and irradiating the material with actinic radiation to react and crosslink the siloxane compound with the cellulosic fibers to impart said durable press properties to the fabric.
Claim 3
Dependent Claim
29 words
A process as set forth in claim 1 including the further step of heating the irradiated fabric to further cure and crosslink the siloxane compound with the cellulosic fibers.
Claim 4
Dependent Claim
18 words
A process as set forth in claim 1 wherein said durable press finishing agent also includes a catalyst.
Claim 5
Dependent Claim
12 words
A durable press textile material produced by the process of claim 1.
Claim 6
Dependent Claim
12 words
A durable press textile material produced by the process of claim 2.
Claim 7
Dependent Claim
12 words
A durable press textile material produced by the process of claim 3.
