Abstract

Organic fibers are treated with aqueous preparations comprising amino-functional organosilicon compounds of the general formulaH2N—R1—SiR2O(SiR2O)iSiR2—R1—NH2wherei is an integer from 1 to 1000,R is an identical or different monovalent hydrocarbon radical having 1 to 18 carbon atoms per radical, andR1 is a divalent hydrocarbon radical having 2 to 10 carbon atoms. The treated organic fibers, particularly in the form of textiles, exhibit a soft hand and good rewettability.
