Abstract

The invention provides a UV-resistant super-fine-denier nylon and water-soluble polyester composite fiber. The composite fiber is prepared from components in parts by weight as follows: 50-60 parts of super-fine-denier nylon and 40-50 parts of water-soluble polyester, wherein the super-fine-denier nylon is prepared from components in parts by weight as follows: 85-90 parts of nylon 6 chips, 5-7 parts of activated carbon, 6-10 parts of nano-silica and 3-5 parts of a modifier; the water-soluble polyester is prepared from components in parts by weight as follows: 40-50 parts of poly terephthalic acid, 26-34 parts of ethylene glycol, 3-7 parts of a catalyst, 2-6 parts of adipic acid, 2-6 parts of zirconium nitrate, 3-5 parts of polyethylene glycol, 4-6 parts of sodium ethylene glycol isophthalate-5-sulfonate and 5-8 parts of a water-soluble adhesive. The UPF (ultraviolet protection factor) of the obtained composite fiber is higher than 50 and the UVA (ultraviolet A) is lower than 2%, and meanwhile, the water-soluble adhesive in the fiber is released after hydrolysis to guarantee more tight adhesion of the super-fine-denier nylon and the water-soluble polyester.

Description

technical field [0001] The invention relates to a composite fiber, in particular to a UV-resistant superfine denier nylon water-soluble polyester composite fiber and a preparation method. Background technique [0002] With the improvement of people's living standards, the requirements for textiles are getting higher and higher. At present, the nylon fibers on the market are short, and there are problems such as rough hand, poor flexibility, poor air permeability, poor water absorption, and easy pilling. Subsequently, ultra-fine denier nylon fibers began to appear on the market, which are soft to the touch and comfortable to wear, but the quality of ultra-fine denier nylon fibers on the market is not high, the fibers are easy to break, not easy to dye, low grade, high defective rate, and poor economic benefits . On the other hand, polyester is a relatively simple synthetic fiber, which has the characteristics of strong durability, good elasticity, not easy to deform, easy to...
