    Abstract: 1,143,067. Coated glass fibrous materials. BADISCHE ANILIN-& SODA-FABRIK A.G. 22 March, 1967 [23 March, 1966; 12 Jan., 1967], No. 13420/67. Heading B2E. [Also in Division D1] Glass fibres and articles formed therefrom e.g. woven and nonwoven fabrics are finished by impregnating with an aqueous liquor which contains at least one film forming high molecular weight substance and, if desired, one or more finely divided pigment and/or conventional additives, and drying the impregnated material, wherein the material is impregnated with aqueous hydrofluoric acid before, during or after the treatment and then dried at a temperature of at least 50‹C. The fibrous material may be first impregnated with an aqueous liquor which contains hydrofluoric acid and at least one film forming high molecular weight substance, and the material then dried at a temperature of at least 50‹C; the impregnated material may be subsequently treated with film forming high molecular weight substances and, if desired, pigment and/or conventional additives. The hydrofluoric acid may be applied at the rate of 0.01-3%, and the film forming high molecular weight substance may be applied in a total amount of 0.05-10%, calculated as anhydrous pure substance and based on the weight of the fibrous material. After drying the fibrous material may be mechanically pressed or bent, or may be callendered at a lineal pressure of 10-60 kg/cm. The high molecular weight substance may be synthetic or naturally occurring and has a molecular weight of at least 10,000; examples are given.
