Abstract
The present invention relates to a unique chemical formulation used in the manufacture of substantially wind-resistant, water-repellent fabrics. The formulation comprises a silicone polymer catalyzed with a tin compound and optionally includes acetic acid and an aromatic solvent. A method for treating fabrics includes depositing the unique formulation on a taut fabric, uniformly distributing it across the width of the fabric and curing that product. Either before or after that treatment, the fabric is padded with or dipped in a bath of silicone or hyrofluorocarbon. Excess solution is removed. Last, the multicoated fibers of the fabric are compressively shrunk. A substantially wind and water-resistant fabric is produced that is not only porous and soft but also durable.
Claims9
A process for coating a woven fabric comprising the steps of:
- (a) depositing on a taut fabric a coating composition having a viscosity up to about 100,000 cps and consisting essentially of:
- (1) a polydimethyl siloxane component present in an amount from about 93 to about 99 percent by weight of the composition, and
- (2) A tin catalyst present in an amount from about 0.5 to about 1.5 percent by weight of the composition,
- (b) uniformly distributing the deposited coating composition on the surface of the fabric,
- (c) curing the fabric from b,
- (d) padding the fabric with a solution selected from a silicone or a fluorocarbon solution, and
- (e) compressing the fabric, whereby it is substantially wind-resistant, water-repellant, and has a good handle.
