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 ##EQU1## and (b) 1 to 20 parts by weight of a specific epoxysiloxane containing at least one structural unit of the formula ##EQU2## and at least two structural units of the formula ##EQU3## 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A treating agent for filling synthetic fibers, said treating agent comprising (a) 1 part by weight of an aminosilane of the formula (I) ##EQU5## wherein R 1 is a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms, or a phenyl group, R 2 is an alkylene group containing 1 to 4 carbon atoms, and R 3 , R 4 , and R 5 , independently from each other, represent an alkyl group containing 1 to 4 carbon atoms, and (b) 1 to 20 parts by weight of an epoxysiloxane containing at least one structural unit of the formula (II) ##EQU6## wherein R 6 and R 7 , independently from each other, represent an alkyl group containing 1 to 3 carbon atoms, and at least two structural units of the formula (III) ##EQU7## wherein R 8 is an alkyl group containing 1 to 3 carbon atoms or the group ##EQU8## R 9 being an alkylene group containing 2 to 5 carbon atoms or a substituted or unsubstituted arylene group containing 6 to 10 carbon atoms.
Claim 2
Dependent Claim
177 words
A treating agent for filling synthetic fibers, said treating agent comprising (a) 1 part by weight of an aminosilane of the formula (I) ##EQU5## wherein R 1 is a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms, or a phenyl group, R 2 is an alkylene group containing 1 to 4 carbon atoms, and R 3 , R 4 , and R 5 , independently from each other, represent an alkyl group containing 1 to 4 carbon atoms, and (b) 1 to 20 parts by weight of an epoxysiloxane containing at least one structural unit of the formula (II) ##EQU6## wherein R 6 and R 7 , independently from each other, represent an alkyl group containing 1 to 3 carbon atoms, and at least two structural units of the formula (III) ##EQU7## wherein R 8 is an alkyl group containing 1 to 3 carbon atoms or the group ##EQU8## R 9 being an alkylene group containing 2 to 5 carbon atoms or a substituted or unsubstituted arylene group containing 6 to 10 carbon atoms.
