摘要： A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units and ethylenically unsaturated monomer units. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with base to make it water soluble. The binders provide a higher wet strength in concentrated salt solutions than in deionized water, and are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

摘要： A salt-sensitive polymeric binder composition which includes a water soluble salt-sensitive polymer component, and a latex processing aid. The binder compositions of the invention exhibit good strength in salt solutions, yet are dispersible in the presence of water. The latex processing aid is effective to reduce the shear viscosity of the binder composition, enabling an aqueous solution of the binder to be sprayed onto an airlaid nonwoven web.

摘要： Heat resistant binders for flexible nonwoven mats may be prepared using an emulsion polymer comprising 100 parts by weight of acrylate or styrene/acrylate monomers, 3 to 6 parts of a blocked, N-methylol containing comonomer, 0 to 3 parts of a water soluble non-blocked N-methylol containing comonomer and 0 to 5 parts of a multifunctional comonomer. The use of the blocked N-methylol containing comonomer permits the incorporation into the latex binders of higher levels of N-methylol functionality with consequent increase in heat resistance. As such, the binders are useful in the formation of heat resistant flexible mats for use in roofing, flooring and filtering materials.

In a preferred embodiment, aqueous emulsions of the imidazolidinone-containing polymers (e.g. 45-60% vinyl acetate, 34-52% butyl acrylate, and 3-6% imidazolidinone) and an acid-curing catalyst (e.g. ZnCl.sub.2) are used as formaldehyde-free binders for nonwoven textiles.
