A trimethyl siloxi silicate derivative having free hydroxyl groups is added to a dimethylpolysiloxane solution of trimethyl siloxi silicate expressed in the following formula (1) by 10 to 60 parts by weight with respect to 100 parts by weight of trimethyl siloxi silicate, and amino modified dimethylpolysiloxane, a surface active agent and/or fine powder is dissolved in an organic solvent or dispersed in water at need, to obtain an agent for treating a water repellency supply cloth according to the present invention. Cloth is impregnated with the agent for treating a water repellency supply cloth to contain a nonvolatile component corresponding to 1.0 to 50.Type: GrantFiled: July 30, 1999Date of Patent: October 30, 2001Assignee: Soft 99 CorporationInventors: Jun-ichi Nonaka, Ryutaro Hidaka

Patent number: 6194329Abstract: A reversible fabric particularly for use in the production of military rainflies is described. The fabric has first and second faces, each of which has a visually distinct color in order that rainflies and other articles made from the fabric can be used to provide inconspicuous shelter in two visually distinct environments. Each of the sides of the fabric provides requisite degrees of visual opacity and infrared reflectance, as well as other functional properties—such as water-resistance, etc. The fabric includes a dyed textile substrate and three coats of pigmented polyurethane having varying compositions; the composite fabric can be produced by a coating and/or laminating process.Type: GrantFiled: January 20, 1999Date of Patent: February 27, 2001Assignee: Brookwood Companies, IncorporatedInventors: Steve Nelson, Benito Boiardi

Patent number: 6143394Abstract: There is disclosed the manufacture and use of nonwoven absorbent mats laminated with barrier film for manhole aprons. The absorbent aprons are used about manholes during routine maintenance of underground transformers, utility cables, etc. The nonwoven aprons are coated to prevent the absorbed liquid from leaching through. The mat is specially designed to absorb contaminated liquid very quickly. The nonwoven mat is made out of cotton shoddy fibers and/or a mixture of synthetic fibers and/or synthetic fibers only with film on one side. The mat has a 36-inch manhole opening in the center thereof. The mat is thin and lays flat to conform to the road. The thickness of the mat ranges from 0.075" to 0.25" in order to avoid any tripping hazard.Type: GrantFiled: January 25, 1999Date of Patent: November 7, 2000Assignee: KG Fibers, Inc.Inventors: Kirit H. Patel, Gulshan Chhabra
