Treating agent for elastic fibers and elastic fibers obtained by using the same

摘要

The present invention provides finishes for elastic fiber, which attain elastic fiber yarn having superior antistaticity, unwinding and package buildup performance and lubricity, and minimize fly sticking on elastic fiber yarn in knitting operation of elastic fiber yarn and cotton spun yarn to enable high-speed knitting operation of fine elastic fiber yarn and cotton spun yarn; and also provides elastic fiber applied therewith. The finishes of the present invention contain 60 to 99.99 parts by weight of at least one of base components selected from the group consisting of silicone oils, mineral oils and ester oils, 0.01 to 20 parts by weight of amino-modified silicones and 0.0001 to 20 parts by weight of phosphate esters containing at least one hydrocarbon group or oxyalkylene group per a molecule. The elastic fiber of the present invention is characterized by the application of the said finish with 0.1 to 15 weight percent of fiber.
