Abstract
Abstract A treating agent for filling synthetic fibers, said treating agent comprising (a) 1 part by weight of a specific substituted aminosilane of the formula ##STR1## and (b) 1 to 20 parts by weight of a specific epoxysiloxane containing at least one structural unit of the formula ##STR2## and at least two structural units of the formula ##STR3## A method for treating synthetic fibers with the above treating agent. Synthetic fibers treated with the above treating agent suitable for use as fillings for quilts.
