Title:
METHOD FOR THERMOFORMING TEXTILE PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/181737
Kind Code:
A1
Abstract:
[Problem] To provide a thermoforming method for obtaining a thermoformed article that exhibits an excellent wear resistance at melt-bonded portions, and an excellent adhesive strength between fabrics and to other kinds of articles. [Solution] A polyethylene terephthalate and a polyethylene having a melt flow rate, measured under conditions of a temperature of 280°C and a load of 2.16 kg, of 10 to 15 g/10 min are prepared. By a conjugate melt spinning method using the polyethylene terephthalate as a core component and the polyethylene as a sheath component, a multifilament yarn in which core-sheath conjugate long fibers having a core component : sheath component mass ratio of 1 to 4 : 1 are collected is obtained. A textile product is obtained by weaving, knitting, braiding, or winding using the multifilament yarn. Thermoforming of this textile product is carried out by heating the textile product to melt the polyethylene and simultaneously to melt-bond the core-sheath conjugate long fibers each other, with the polyethylene terephthalate retaining its initial fiber form.
