Problems solved by technology

The hot-melt yarn used for fly-knit shoe uppers is mainly polyester hot-melt yarn. Compared with polyester hot-melt yarn, nylon hot-melt yarn used in knitted shoe uppers can make the shoe upper more elastic and stretchable. Strong, its future application potential is immeasurable; the melting point of nylon thermal fuse used to prepare fly-woven shoe uppers in the market is mostly between 130-160 °C, and the melting point is still relatively high, which has led to the preparation of fly-woven shoe uppers. The cost is relatively high and the process is more complicated

Abstract

The invention discloses a low-melting-point nylon hot-melt yarn for preparing fly-woven shoe uppers, which is formed by polymerizing polyamines and polyacids as reactants, and adding catalysts, modifiers and other auxiliary agents for further reaction; A mixture of decanediamine, pentaethylenehexamine and (1R,2R)‑(‑)‑N‑(p-toluenesulfonyl)‑1,2‑diphenylethylenediamine was chosen for the polyamine; A mixture of sebacic acid, terephthalic acid, and dodecenylsuccinic acid was selected; bis(pentamethylcyclopentadiene) zirconium dichloride, N,N-dimethylanilinium were selected as catalysts A mixture of tetrakis(pentafluorophenyl)borate; the modifiers are 3,5-diamino-1,2,4-triazole, bicyclo(2.2.2)oct-5-ene-2 , a mixture of 3‑dicarboxylic anhydride and 2,2‑bis[4‑(4‑aminophenoxy)phenyl]‑1,1,1,3,3,3‑hexafluoropropane. Nylon thermal fuse not only has a lower melting point, but also has greater fiber strength and elongation, and also has stronger anti-ultraviolet properties and better color fastness, and can be used to prepare fly-knit uppers.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a low-melting-point nylon hot-melt yarn used for preparing fly-woven shoe uppers. Background technique [0002] Thermal fuses are divided into two categories: polyester thermal fuse and nylon thermal fuse, and can be divided into two types: full melt and semi melt. At present, the melting point of thermal fuses on the market is generally between 85-180°C; in application, other fibers are mixed with thermal fuses, and then pressure is applied to the fabric under dry heat / humid heat. When the temperature is higher than the melting point of the thermal fuse, the thermal fuse gradually melts. While the other fibers remain unchanged, they are bonded together by thermal fuses. Therefore, the use of thermal fuse can replace other chemical solvent-based adhesives, avoiding the pollution of organic volatiles, and has the advantages of environmental protection and greenness. At the same tim...
