A process useful for imparting abrasion resistance, resistance to frosting, wrinkle resistance, crease retention, wash-and-wear characteristics, durable press characteristics, and permanent press characteristics to cellulosic textile materials and to improve the wet strength, water absorption, and other properties of cellulosic paper. The process comprises; (a) impregnating the textile material or the paper with an aqueous aminoplast system comprising at least one aminoplast and at least one mem...

A coated paper utilizing a clay coating containing asbestos in the amount of 0.1 to 10 percent based on the weight of clay.

The present invention renders an electrophoretic membrane having a molecular weight range from 10,000 to 150,000 transparent by first impregnating the membrane with a lower alkyl alcohol and thereafter treating the membrane with an ether until the membrane becomes transparent. The temperature of the solvent liquids generally ranges from 10.degree. to 35.degree. C.

Stable, homogeneous thermosetting, liquid resin compositions useful for treating the surface of felted mineral fiber-board panels which are bonded with a hydrophilic binder to reduce sag and method of making the same. Compositions of this invention comprise a copolymer blend of (1) from about 25% to about 55% by weight, of a melamine-formaldehyde copolymer and (2) from about 75% to about 45% by weight of a urea-formaldehyde copolymer. These compositions may be stabilized through the addition of ...

A soluble paper having a coating of polyvinyl alcohol. The soluble paper comprises carboxy methyl cellulose, and the sodium or potassium salts of carboxy methyl cellulose. The coated paper is soluble in either high or low temperature water.

A small amount of a bismuth compound is incorporated with kaolin clay during the processing of the clay. The clay product is employed in an aqueous coating composition adapted for coating book or magazine paper in order to increase the opacity of the resulting clay film.

This invention relates to a tubular casing of cellulose hydrate having a coating on its inner side composed of a mixture of substances cross-linked by chemical reaction, which mixture is obtained when an aqueous liquid containing A. 1 to 10 per cent by weight, calculated on the total weight of the liquid, of a water-soluble aminoplast precondensate, B. 1 to 4 per cent by weight, calculated on the total weight of the liquid of a fluorine-containing two-component system from .beta..sub.1. polymers...

The inner surfaces of a pair of substrates of a liquid crystal display are treated with a solution of a surfactant to provide a uniform stable alignment of the liquid crystal material confined between the inner surfaces. The inner surfaces are first wetted by the soluton of the surfactant, a silane derivative, and the solution is then heated, while the inner surfaces are in contact with the solution, to a temperature between about 75.degree.C and a temperature just below the boiling point of the...

Textile size compositions which are dispersible in water and comprise an alkali metal and/or ammonium salt of a styrene-maleic anhydride copolymer containing as a copolymerized component a diester of an olefinically unsaturated dicarboxylic acid or anhydride and a monohydric alcohol and/or a polyester of such an acid or anhydride and a polyhydric alcohol. Also, textile size compositions which are dispersible in water and comprise a mixed salt of a styrene-maleic anhydride copolymer, wherein 20 t...

Glass fiber filament bundles such as cords for rubber reinforcement are impregnated and coated with an elastomer composition such that the coated cord maintains adhesion and tensile strength even in a moist environment due to the inclusion in the coating of a chemically treated diatomaceous earth. These chemically treated diatomaceous earths contain a major portion of an alkali earth metal silicate.
