Abstract

The invention discloses an ice-resistant fabric containing polytetrafluoroethylene. The ice-resistant fabric comprises first yarns and second yarns combined with the first yarns, the first yarns comprise flame-retardant high-temperature-resistant carbonization fibers, the second yarns comprise polytetrafluoroethylene fibers, the weight ratio of the first yarns to the second yarns in the ice-resistant fabric is 1:1-20:1, and the first yarns and the second yarns are woven into a base fabric finished into the ice-resistant fabric containing the polytetrafluoroethylene. The ice-resistant fabric is simple in structure and high in practicability, has ice-resistant, waterproof, windproof, flame-retardant, anti-static, antibacterial, moisture permeable and spying prevention disguising functions, and can be widely applied to special protective clothing for military, fire fighting, gas defense and the like.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a functional fabric, in particular to an ice-resistant fabric containing polytetrafluoroethylene. Background technique [0002] Polytetrafluoroethylene fiber (polytetrafluoroethylenefibre), abbreviated as PTFE, is called fluorine fiber in China. A synthetic fiber made of polytetrafluoroethylene (see fluororesin) as raw material, cut or fibrillated after spinning or filming %~50%. In its molecular structure, the volume of fluorine atoms is larger than that of hydrogen atoms, and the binding force of fluorine-carbon bonds is also strong, which plays a role in protecting the entire carbon-carbon main chain, making PTFE fibers have excellent chemical stability and excellent corrosion resistance. Compared with other synthetic fiber varieties; the surface of the fiber has a waxy feel and a small friction coefficient; the actual use temperature is 120-180 ° C; it also has good w...
