FIELD: textiles, paper.
SUBSTANCE: invention relates to an aqueous binder for manufacture of non-woven product. The water binder for manufacture of non-woven product is an adduct of carbohydrate polymer and multifunctional cross-linking agent selected from the group consisting of a polybasic acid, its salt, its anhydride and their mixtures. The water binder is obtained by combining carbohydrate polymer and multifunctional cross-linking agent. The water binder is used to bond the glass fiber or mineral wool fibers. To do this, the glass fiber or mineral wool fibers are contacted with the water binder, and the mixture is heated for a time sufficient to cure. The bonded by water binder product of glass fiber is used in the material for thermal insulation of buildings. In the manufacture of water binder the renewable materials are used.
EFFECT: water binder is free of formaldehyde and has a low cost.
