Abstract
Official abstract text for this publication.
A process for modifying a silicone elastomeric-based surface of a textile article where the coefficient of friction (COF) of the silicone elastomeric-based surface is generally reduced by at least 5% is disclosed. The process comprises subjecting the silicone elastomeric-based surface of the textile article to vacuum ultraviolet (UV) radiation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for modifying a silicone elastomeric-based surface of a textile article, said process comprising: subjecting the silicone elastomeric-based surface of the textile article to vacuum ultraviolet radiation; wherein the vacuum ultraviolet radiation is performed using a low-pressure mercury lamp; and wherein the coefficient of friction of the silicone elastomeric-based surface is reduced by at least 5%. 2. The process according to claim 1 , wherein the silicone elastomeric-based surface of the textile article consists of silicone elastomer. 3. The process according to claim 2 , wherein the silicone elastomer is the reaction product of a hydrosilylation or peroxide cure of an alkenyl-functional organopolysiloxane and a Si—H functional organopolysiloxane. 4. The process according to claim 1 , wherein the textile article is an airbag. 5. The process according to claim 1 , wherein the textile article is a silicone elastomer coated airbag. 6. The process according to claim 1 , wherein the textile article is coated, and is subsequently subjected to vacuum ultraviolet radiation. 7. The process according to claim 1 , wherein the vacuum ultraviolet radiation is performed on a conveyor belt. 8. A textile article having a silicone elastomeric-based surface, which surface is modified by the process according to claim 1 . 9. The textile article according to claim 8 , wherein the silicone elastomeric-based surface has a modified surface layer of less than 1 mm in thickness. 10. An airbag formed by the process according to claim 1 . 11. A parachute formed by the process according to claim 1 . 12. An outdoor textile formed by the process according to claim 1 .
