The present invention provides methods for chemically embossing and debossing fabric. A composition comprising polyvinyl alcohol is applied to fabric in the shape of a design, and the fabric is dried. Upon the fabric drying, the surface of the fabric is embossed and/or debossed in the shape of the design. In particular embodiments, the composition comprises polyvinyl alcohol that is at least about 90% hydrolyzed. A kit for embossing and/or debossing fabric includes a composition comprising polyvinyl alcohol inside of a container, and one or more applicators.

A polyvinyl alcohol (PVA)-based airbag base fabric aqueous coating material is described. A blocked polyisocyanate component (B-NCO) and liquid polyol are added to polyvinyl alcohol as a cross-linkage improver and a plasticizer, respectively. The B-NCO is composed of or based on a medium-molecular-weight form as a polyether-modified prepolymer, and used concurrently with a low-molecular-weight form in a small amount. The base fabric coating material is applied on one or both of the sides of a cloth of the base fabric and heated. The acquired coating film is a water-insoluble coat and the coating has excellent heat and moisture resistance (hot water resistance) and flexibility.

Disclosed is an inorganic fiber sizing agent that contains an epoxy compound, an aliphatic sulfonic acid salt, and a nonionic surfactant.

The invention concerns a novel binder system and its use for consolidating textile fabrics, as well as to products containing such consolidated textile fabrics. The materials according to the invention are suitable for the manufacture of reinforcing inserts, optionally in combination with at least one further textile fabric, for coated sarking membranes, roofing and waterproofing sheets, as textile backings or textile reinforcement in flooring, in particular in fitted carpets and PVC flooring, or in facers in wall coatings both in the interior and exterior of buildings, as well as in furniture.
