DISPERSING NON-WOVEN MATERIAL Russian patent published in 2017 - IPC D04H1/587 

FIELD: textile, paper.

SUBSTANCE: invention describes a method to make a dispersing non-woven substrate in an aqueous medium, including: a) making an aqueous non-woven binder comprising a selected emulsion polymer, where the polymer has been modified with a compound containing a trisubstituted atom N, _{the compound} value is in pKb from 4 to 7; b) interreacting of a non-woven substrate with an aqueous non-woven binder; c) heating the interreacting non-woven material at the temperature from 120 to 220°C; and d) immersing the interreacting heated non-woven material into an aqueous medium with a finite value of pH<5. The invention also describes a dispersing non-woven substrate in an aqueous medium, made with the said method, and a method for getting a dispersing non-woven material in an aqueous medium.

EFFECT: improved material properties.
