Temperature-resistant high-strength wrapping yarn, preparation method thereof and shoe upper fabric

Abstract

The application provides a high-temperature-resistant and high-strength wrapping yarn, a preparation method thereof and a vamp fabric, and the high-temperature-resistant and high-strength wrapping yarn comprises a wrapping layer and a core layer, the core layer is an ultrahigh molecular weight polyethylene multifilament, and the wrapping layer comprises one or more of long carbon chain polyamide block elastic fiber, thermoplastic polyester elastomer fiber, thermoplastic polyurethane fiber, polyester, polyarylate, spandex, chinlon, aramid fiber and polyolefin fiber; and the wrapping layer is double-layered. The high-temperature-resistant and high-strength wrapping yarn is prepared by wrapping the ultrahigh molecular weight polyethylene yarn with double-layered reverse wrapping. The vamp fabric is knitted by using the open-hole heald weaving method, and the weft yarn is the high-temperature-resistant and high-strength wrapping yarn. The application has the advantages that the use range of the ultrahigh molecular weight polyethylene in the fabric can be effectively widened, and the damage to the fiber strength can be effectively reduced at the heat setting temperature of 130 DEG C to 150 DEG C. The vamp fabric has high burst strength, tear strength, tear strength and bending resistance, and is an excellent light-weight and high-strength vamp fabric.
