METHOD OF PRODUCING NONWOVEN TEXTILE MATERIALS HAVING SORPTION AND HYDROPHOBIC PROPERTIES USING OLIGO(3-AMINOPROPYL)(OCTYL)ETHOXYSILOXANES Russian patent published in 2011 - IPC D06M15/643 D06M13/507 D04H3/10 D04H1/46 B01J20/32

Abstract RU 2431707 C1

FIELD: chemistry.

SUBSTANCE: method involves saturating fibre with an alcohol solution or aqueous emulsion containing 0.5-10.5% oligo(3-aminopropyl)(octyl)ethoxysiloxane, drying in air and forming a nonwoven web followed by needling. Thermal treatment at 100-140°C for 5-10 minutes is carried out in order to hold the oligo(3-aminopropyl)(octyl)ethoxysiloxane on the surface of the fibre.

EFFECT: nonwoven material has high strength, sorption capacity, water absorption and soaking capacity.
