  • Method of application, and product thereof
    Patent number: 4369231
    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 hydrofluorocarbon. 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.
