Title:
RESIN-COATED YARN, AND SYSTEM AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/075034
Kind Code:
A1
Abstract:
The present invention relates to a resin-coated yarn, and a system and method for manufacturing same, wherein a hot-melt resin is coated on a yarn with inorganic powders and thus the yarn has increased initial elastic modulus (Young's Modulus) and improved sphericity and centrality. The resin-coated yarn manufacturing system according to the present invention comprises: a core yarn supply unit to which a core yarn reel having a core yarn to be coated wounded therearound is mounted; a resin coating unit which includes a coating nozzle through which the core yarn released and transported from the core yarn supply unit passes and is configured to coat and extrude a resin mixture on the surface of the core yarn by supplying the resin mixture to the coating nozzle, the resin mixture being obtained by mixing inorganic particles with a molten hot-melt resin; a primary cooling unit for performing primary cooling by spraying cooling water mist and cooling air to the core yarn (hereinafter referred to as a "coated yarn") coated with the resin mixture transported through the resin coating unit; a secondary cooling unit for performing secondary cooling by passing the coated yarn having passed through the primary cooling unit through cooling water stored in a water storage tank; and a coated yarn recovery unit having an unloader shaft to which a recovery reel is rotatably mounted such that the coated yarn having passed through the secondary cooling unit is wound around same.
