Abstract

The invention relates to a synthetic fiber capable of removing formaldehyde and a preparing method thereof, and belongs to the technical field of functionality synthetic fibers. The synthetic fiber is prepared from, by weight, 70 parts to 80 parts of polyacrylonitrile, 60 parts to 70 parts of polybutylene terephthalate, 60 parts to 70 parts of rod-type zinc oxide, 1 part to 5 parts of active carbon nanoparticles, 1 part to 5 parts of non-ionic surfactants and 80 parts to 86 parts of ethyl alcohol. The preparing method includes the steps that after being subjected to ball milling for 30 min to 36 min, the solid raw materials are preheated for 20 min to 28 min under the condition of 80 DEG C to 85 DEG C, and mixing and prilling are carried out in a mixing machine; master batch obtained by mixing and prilling is subjected to fusing spinning, the temperature is 400 DEG C to 450 DEG C, the pressure is 1*10<5> Pa to 3*10<5> Pa, and a finished product is obtained. The synthetic fiber has the good formaldehyde decomposing function, can be applied to curtains, clothes and textiles, low in production cost, simple and controllable in technology and suitable for industrial production.

Description

technical field [0001] The invention relates to a synthetic fiber capable of removing formaldehyde and a preparation method thereof, belonging to the technical field of functional synthetic fiber. Background technique [0002] The petrochemical industry is an important part of the chemical industry, plays an important role in the development of the national economy, and is one of the pillar industries of our country.
