Abstract

The invention discloses a basalt fiber chenille knitted fabric, which is a basalt fiber chenille knitted fabric formed by crocheting basalt fiber chenille yarn through knitting equipment, and the basalt fiber chenille yarn includes a core The material of the feather yarn is basalt fiber or basalt fiber and quartz glass fiber, high silica glass fiber, aluminum silicate fiber, polyamideimide fiber, polyether ether ketone fiber, polyphenylene sulfide Fiber, polysulfone-based amide fiber, poly-p-phenylene benzobisoxazole fiber, polybenzimidazole fiber, polytetrafluoroethylene fiber, polyimide fiber or aramid fiber or a mixed yarn of one or more; The core wires are two strands, and the feather yarn is sandwiched between the two core wires after the core wires are twisted. The basalt fiber chenille knitted fabric processed by the knitting machine has a large space gap between the yarns and a small air resistance, which can improve the air filtration efficiency.

Description

technical field [0001] The patent of the invention relates to a knitted fabric for air purification, in particular to a basalt fiber chenille knitted fabric. Background technique [0002] The core thread of the chenille yarn in the prior art is twisted with acrylic yarn as a raw material, and the feather yarn is cut into short feathers with viscose yarn as a raw material, which are widely used in the fields of home textiles and knitted garments. The fabric that adopts common chenille yarn to weave generally gets its decorative effect more, and its comfortableness aspect is relatively poor. Rarely used for air filtration purposes. [0003] After China experienced the "soot-type pollution" brought about by the industrial revolution in the 18th century and the "photochemical smog pollution" brought about by the petroleum and automobile industries in the 19th century, modern people are experiencing "severe PM2.5-type smog" with Chinese characteristics. The third pollution peri...
