Silicone-based softening agent for synthetic fibers

摘要

The inventive composition is a silicone-based softening agent for synthetic fibers such as waddings of polyester fibers without the disadvantage of yellowing caused by heat or in the lapse of time. The essential ingredients of the inventive composition are a combination of two different amino-substituted organopolysiloxanes, an opoxy-containing alkoxysilane compound such as 3-glycidyloxypropyl methyl dimethoxy silane and a monoepoxy compound such as glycidyl alcohol each in a specified amount. Characteristically, one of the amino-substituted organopolysiloxane components is a reaction product of an amino- substituted organopolysiloxane and an organic opoxy compound.
