Abstract
A composition is disclosed which comprises an amino radical-containing organopolysiloxane and an organopolysiloxane containing at least 3 epoxy radical-containing organic groups in each molecule. The composition of the present invention imparts to polyester fibers excellent smoothness, elastic resilience, and compressive recovery, as well as a high resistance to permanent setting
