    摘要: Nonwoven fabrics that have excellent wet strength and dry strength are formed by adding to an aqueous suspension of natural and/or synthetic fibers a binder comprising (a) an anionic polymer latex and (b) a mixture of alkali metal salts of disproportionated rosin and fortified rosin, precipitating the binder on the fibers, and forming the treated fibers into a nonwoven fabric.
