摘要： An improvement in the process of treating textile materials with aqueous compositions of polyisocyanate materials containing freeisocyanate groups is obtained by incorporating silica sol in the composition. The presence of the silica sol allows the compositions to be applied by the exhaustion method. Optionally, emulsion stabilizer, e.g., polymers of vinyl monomers can be added, as well as electrolytes which speed up drawing onto the textile fibers.

摘要： TEXTILE MATERIALS ARE FINISHED BY TREATMENT WITH AN AQUEOUS BATH WHICH CONTAINS A POLYURETHANE PREPOLYMER HAVING FREE ISOCYANATE GROUPS WHICH IN TURN HAS BEEN OBTAINED FROM AN ORGANIC COMPOUND HAVING ACTIVE HYDROGEN CONTAINING GROUPS AND AN ORGANIC POLYISOCYANATE, AND AN ORGANO POLYSIOLOXANE HAVING A MOLECULAR WEIGHT OF TO ABOUT 25,000 AND CONTAINING AT LEAST TWO ACTIVE HYDROGEN CONTAINING GROUPS. THE ORGANO POLYSILOXANE IS REACTIVE WITH THE ISOCYANATO PREPOLYMER O THE TEXTILE SUBSTRATE IN ORGER TO GIVE THE TEXTILE MATERIAL A FULL PLEASANTLY SOFT, SUPPLY HAND AND REDUCE SUSCEPTIBILITY TO SOILING. ONE MAY USE POLYMERS OR COPOLYMERS PREPARED FROM VINYL OR DIVINYL MONOMERS IN THE AQUEOUS BATH ALONG WITH THE OTHER COMPONENTS.

摘要： A process for felt-proofing and dimensionally stabilizing textiles containing keratinous fibers with a single aqueous bath which contains both reducing agents and polyurethane polymers containing free isocyanate groups as well as polymers or copolymers based on vinyl or divinyl compounds. The aqueous bath has a pH of about 5.5 to about 6.5. The reducing agents used are salts or sulphurous acid or pyrosulphites. The free isocyanate groups of the polyurethane are bound to aliphatic carbon atoms.
