TREATING AGENT FOR ELASTIC FIBERS AND ELASTIC FIBERS OBTAINED BY USING THE SAME

摘要

It is intended to provide a treating agent for elastic fibers which can give an elastic fiber excellent in antistatic properties, fibrillation properties, cheese winding form and smoothness, lessens cotton dust adsorption in the step of cross-knitting the elastic fiber with cotton yarns and thus enables high-speed knitting of fine elastic fiber with cotton yarns; and elastic fibers having been processed with the treating agent. Namely, a treating agent for elastic fibers which comprises 60 to 99.99 parts by weight of at least one member selected from among silicone oil, mineral oils and ester oils as the base component together with from 0.01 to 20 parts by weight of an amino- denatured silicone and from 0.0001 to 20 parts by weight of a phosphoric acid ester having at least one hydrocarbyl group or oxyalkylene group per molecule. Elastic fibers characterized by having from 0.1 to 15% by weight of the above-mentioned treating agent imparted thereto.
