AQUEOUS COMPOSITION AND METHOD FOR TREATMENT OF TEXTILE

摘要

PURPOSE: To obtain an aqueous dispersion capable of imparting softness to a woven fabric and exhibiting good rewettability by dispersing a mixture comprising a cationic compound and a mixture of a polydiorganosiloxane having a specific viscosity with specific liquid methylsiloxanes in water. CONSTITUTION: This aqueous emulsion is obtained by adding (A) a cationic compound [e.g. ditallowdimethylammonium chloride] and (B) a mixture of (B1 ) 5-30 wt.% of a polydiorganosiloxane having at least 300 Pa.s viscosity at 25 deg.C in which 80% of all the organic substituent groups are methyl groups and the remaining substituent groups are 2-6C monovalent hydrocarbons with (B2 ) 95-70 wt.% of a liquid methylsiloxane containing 2-8 silicon atoms in the molecule into water. The resultant emulsion can be used to treat a woven fabric in a rinsing step to thereby afford a drape ranging from a soft touch to a hard and dense touch.
