AI Technical Summary

Technical Problem

Existing thermal insulation fibers do not provide good insulation in the absence of light or in low-temperature environments, making it difficult to meet the demand for high-intensity insulation.

Method used

A twelve-hole far-infrared heating fiber was prepared by plasma ball milling of nano-tourmaline and titanium powder, followed by copolymerization with terephthalic acid and ethylene glycol to form a modified polyester masterbatch. The masterbatch was then irradiated with a high-energy electron beam and coated with a multi-benzene ring film to enhance far-infrared radiation and thermal stability.

Benefits of technology

It improves the far-infrared radiation intensity and thermal stability of the fiber, enhances its heat retention performance in various environments, and extends its service life.
