Salt-sensitive binder composition with latex processing aid

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.
