WIPO Patent Application WO/2020/009271
Kind Code:
A1
Abstract:
Disclosed are: a thermoplastic polyurethane yarn in which, in a thermoplastic polyurethane composition composed of isocyanate, glycol, and polyol, succinate is used as polyol, and when the isocyanate, glycol, and succinate are polymerized, a nano-silica having a particle size of 100 nm or less is mixed, and thus a crystallization rate during melt extrusion is increased such that the yarn can be continuously spun without being cut during cooling and drawing processes and has stretch and recovery characteristics; and a fabric manufactured from the yarn.
