Abstract

The invention discloses a production method for compound blocking cloth, which relates to the technical field of non-woven fabrics. The production method comprises feeding each raw material, rough opening, fine opening, carding, pre-needling, finish needling and thermal setting, and is characterized in that: raw materials include glass fibers, high-performance stainless steel fibers, ceramic fibers and basalt fibers, and are subjected to PTFE (Polytetrafluoroethylene) treatment after thermal setting. In the invention, a high-performance and high-function fiber combination prepared by compounding the high-performance stainless fibers, ceramic fibers and basalt fibers is added, so that a compound high-temperature-resistant filtering material product with a better using effect is obtained, the suitable temperature can be up to 320 DEG C in maximum, and the warp-direction and weft-direction strength is improved. The product is subjected to the PTFE treatment at a later stage, so that the softness and wear resistance of the fibers are improved, the static electricity resistance of the fibers is enhanced, the bonding firmness between a carpet and base cloth is enhanced, the carpet and the base cloth are protected from being worn or corroded, and the dust stripping property of a carpet surface is improved.

Description

technical field

[0001] The invention relates to the technical field of production of non-woven fabrics, in particular to the production process of needle-punched glass fibers. Background technique

[0002] Glass fiber is drawn from molten glass and is an inorganic non-metallic material. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It is made of glass balls or waste glass as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. In general, glass fiber has good heat resistance and corrosion resistance, high mechanical strength, and can be used at high temperatures of 280-300 °C. At the same time, it has the characteristics of good dust stripping. It is because of these characteristics that glass fiber is widely used in dust collection in cement kilns and carbon black recovery.

[0003] However, due to the single composition of glass fiber and the fact that the fiber compo...
