Abstract

A multifunctional fiber with full-spectrum infrared radiation, flame retardant and antibacterial functions, including a composite masterbatch having a water content of 30-50 ppm and accounting for 10-12% by weight, polyethylene terephthalate having a water content of 25-30 ppm or polycaprolactam high polymer having a water content of 50-70 ppm and accounting for 88-90% by weight; the fiber and its fabric possess multiple functions such as spectral heating, flame retardancy, anti-bacteria and anti-virus; after being illuminated for 5-10 minutes, the temperature difference of the fiber fabric of the present invention is higher than 15-20° C., the far-infrared emissivity is greater than 98%, the radiation temperature rise is greater than 3.0° C., the CLO value is greater than 0.5, the heat transfer coefficient is greater than 18.0w/(m²k), and the thermal resistance is less than 0.05 (m²k)/w. The antibacterial rate against Escherichia coli, Staphylococcus aureus, Candida albicans and pneumobacillus is greater than 99.0%.
