METHOD FOR PRODUCING OF FILLED NON-WOVEN MATERIAL Russian patent published in 2008 - IPC D04H1/64 C08J3/28 

FIELD: textile industry, in particular, processes for manufacture of non-woven materials.

SUBSTANCE: method involves producing filled non-woven material obtained by combined process on the basis of physicochemical technology including impregnation with liquid phase composition exposed to wave action, with liquid phase composition containing low-emulsifier and emulsifier-free polyacrylic latexes; providing exposure to wave action in resonance mode after mechanical mixing of components; subjecting material to squeezing, drying and thermal processing.

EFFECT: reduced washing away of components used in production of non-woven materials during utilization of said materials, improved uniformity in distribution of filler and provision for keeping sorption capacity of materials with regard to admixtures in liquid media.
