Title:
SILICONE-COATING APPARATUS AND COATING METHOD FOR ELASTIC YARN
Document Type and Number:
WIPO Patent Application WO/2020/111691
Kind Code:
A1
Abstract:
The present invention relates to a silicone-coating apparatus and and coating method for elastic yarn. More specifically, in order to improve workability and quality by applying an anti-slipping silicone in a state in which elastic yarn obtained by twisting a polyurethane stretch yarn and a polyester or nylon chemical yarn is stretched, a tension part in a tense state, which is generated by increasing the tension of elastic yarn, is injected into a coater during the injection of the elastic yarn obtained by twisting a polyurethane stretch yarn and a polyester or nylon chemical yarn, so that a silicone-coating solution is impregnated into the tension part in the tense state, the silicone-coating solution is dried to be silicone in the tense state, the elastic yarn is controlled so as to be reduced to a relaxed part in the relaxed state, the coating amount of silicone impregnated onto the surface of the elastic yarn is controlled in an adjuster so that the thickness and weight thereof are the same and, simultaneously, surface treatment is performed thereon so that the surface of the coating solution becomes smooth, and the relaxed part of the elastic yarn in the relaxed state is wound around a winding roller, and thus the present invention has advantages that the silicone-coating attached to the surface of the elastic yarn is not damaged even in the tense state and the reduced state, and since, during silicone-coating, silicone can be applied while a yarn passes through the surface of a coating roller immersed in the coating solution, an extruder is not used, and thus coating can be performed regardless of the thickness of the elastic yarn.
