Abstract

The invention relates to an antibiosis multifunctional fiber material and a relative preparation, wherein the material is composed of polypropylene and antibiosis multifunctional mother particles which mass ratio is 80-85:15-20, the mother particle comprises 4-5% negative ion micro powder, 5-8% optical catalysis micro powder, 2-3% far infrared micro powder, 4-5% inorganic antibiosis powder, and 60-78% PP (polypropylene) as mass percentage. The material is extruded into the mother particles to be mixed with the polypropylene, spinned, drawn, twisted and oiled. The antibiosis rate of the invention can reach 99%, which can remove 80% formaldehyde in 2h, while the negative ion release rate is 1000r/cm3.

Description

technical field [0001] The invention relates to a fiber material belonging to the field of materials, in particular to an antibacterial multifunctional fiber material capable of removing formaldehyde and releasing negative ions. Background technique [0002] There are various harmful microorganisms in the environment where people live, and they will have a negative impact on human life, especially in some humid places (such as kitchens, bathrooms, etc.) in the home environment, which are more likely to breed microorganisms, resulting in The bacteria concentration in the indoor air and the bacteria concentration on the surface of the article increase. [0003] With the continuous improvement of people's material and cultural living standards, people look forward to health and the desire to pursue a comfortable life is also increasing. Therefore, fibers with health care functions are one of the directions that relevant researchers are currently working on. Fibers with antibac...
