A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer incorporating the residue of vinyl acetate, a carboxylic acid, and a vinyl ester of a saturated aliphatic monocarboxylic acid having between (6) and (18) carbon atoms in the carboxylic acid moiety. The copolymer is neutralized at least to the extent that 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 polymérique sensible aux sels, destiné à être utilisé dans des bandes de tissus fibreux, ledit liant contenant un copolymère incorporant le résidu d'un acétate de vinyle, un acide carboxylique, et un ester de vinyle d'un acide monocarboxylique aliphatique saturé ayant de (6) à (18) atomes de carbone dans le groupe acide carboxylique. Le copolymère est neutralisé au moins dans une proportion telle qu'il soit hydrosoluble. Les liants sont particulièrement adaptés au renforcement de bandes de tissus fibreux non tissés dans des articles jetables, tels que des lingettes humides, des produits d'hygiène personnelle, des couches, et similaire.
