PURPOSE:To provide the subject composition comprising an organopolysiloxane composition containing specific components and capable of being coated on the surfaces of the base fabrics of nylon fibers and/or polyester fibers to impart good characteristics such as good water repellency, sealability and bending resistance to the base fabrics. CONSTITUTION:A base fabric-treating agent composition comprises (A) 50-90 pts.wt. of a both terminal hydroxyl groups-protected diorganopolysiloxane of the formula (R is 1-20C substituted or non-substituted monovalent hydrocarbon; m is 20-10000), (B) 1-30 pts.wt. of a crosslinking agent (e.g. an odorless oxime type crosslinking agent) for the component A and (C) 1-50 pts.wt. of an inorganic filler (e.g. silica or diatomaceous earth), the total amount of the composition being 100 pts.wt., dispersed in an organic solvent (e.g. dichloroethane or methylene chloride). The agent can be coated on a nylon and/or polyester fiber base fabric and dried at ordinary temperature to readily provide the base fabric capable of maintaining good water repellency, water resistance, sealability, etc., for a long period of time. The coated base fabric is especially suitable as an excellent raw material for paraglider canopies. |
