Process for preparing self-crosslinkable aminosiloxane emulsion

摘要

A process for preparing a self-crosslinkable aminosiloxane emulsion, comprising: dispersing by emulsification in water in the presence of a cationic surface active agent and a nonionic surface active agent: (A) a specific organosilicon compound that may have a hydroxyl group and/or an alkoxy group; (B) a specific organosilicon compound having a nitrogen-containing monovalent hydrocarbon group; and (C) a specific organosilane having a hydroxyl group and/or an alkoxy group, and or a partial hydrolysis-condensation product thereof; subsequently carrying out emulsion polymerization in the presence of an alkaline catalyst; and thereafter neutralizing the reaction product. The resulting emulsion is useful as softening agents, smoothing agents or feeling improver for all sorts of textiles, and binders between fibers.
