Abstract

The invention discloses a chenille warp-knitted spacer fabric used for air filtration. The chenille warp-knitted spacer fabric is a three-dimensional chenille warp-knitted spacer fabric made of chenille yarns. The three-dimensional chenille warp-knitted spacer fabric comprises a surface layer and an interlayer. The fabric is advantaged in that 1, the chenille warp-knitted spacer fabric has three-dimensional spatial structure, strength is large, heat dissipation and gas permeability are good, and the fabric has unique characteristics of inhibiting growth of bacteria and effectively keeping out ultraviolet penetration; 2, compared with a needle punched filter cloth and a filter bag in the same density, the fabric is light in weight, high in filtering efficiency, and low in resistance, and the fabric has incomparable performance that a conventional air filtering material made of glass fibers and chemical fibers cannot match; 3, the chenille warp-knitted spacer fabric is characterized by breathable and environmentally friendly, and light weight, strong support force, and good resilience, and the fabric can be applied in fields of air filtration and purification, and can be used to replace a conventional filtration material for filtering and purifying air.

Description

technical field [0001] The invention relates to a warp-knitted spacer fabric, in particular to a chenille warp-knitted spacer fabric for air filtration. 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 period ma...
