Binding Composition.

摘要

Binding composition for non-woven fibrous materials, comprising a copolymer emulsion in which at least 30 % by weight of the monomer content is vinyl C1 to C4 alkanoate, 0.5% to 3% by weight of N-(n-butoxymethyl) acrylamide as a post polymerisation cross-linking agent and 0.5 % to 5% by weight of acrylamide. The combination of N-(n-butoxymethyl) acrylamide with acrylamide leads to low formaldehyde content together with good physical characteristics.
