A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units, acrylate monomer units, and N-alkyl acrylamide units. The copolymer is neutralized at least to the point where it is water soluble. The binders are particularly suitable for strengthening non-woven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

L'invention concerne un liant polymère sensible au sel à utiliser dans des bandes fibreuses. Ce liant contient un copolymère d'unités monomères d'acide carboxylique, d'unités monomères d'acrylate, et d'unités de N-alkyle acrylamide. Le copolymère de l'invention est neutralisé au moins au point où il est soluble dans l'eau. Les liants de l'invention sont particulièrement appropriés à un renforcement de bandes fibreuses de non tissé d'articles jetables, notamment, des lingettes humides, des produits de soins personnels, des couches et analogues.
