Nonwoven products bonded with binder emulsions of vinyl acetate/ethylene copolymers having improved solvent resistance |
摘要 |
A copolymer emulsion for bonding nonwoven products comprising an aqueous medium having colloidally dispersed therein a copolymer consisting essentially of vinyl acetate, 5-35 wt % ethylene and 2 to 10 wt % of an amide functional crosslinking comonomer which is N-methylolacrylamide or a compound of the formula R-NH-(CH2)n-CH(OR')2 where R is (meth)acryloyl, R' is a C1-C4 alkyl group and n is 3 or 4, the copolymer emulsion prepared in the presence of 0.1 to 1 wt % polyvinyl pyrrolidone, based on vinyl acetate in the copolymer. Such emulsion binder copolymers demonstrate improved solvent resistance.
