Spunlaced nonwoven filter material and weaving process thereof

Abstract

The invention discloses a spunlaced nonwoven filter material and a weaving process thereof. The spunlaced nonwoven filter material is formed by weaving bamboo charcoal fibers, linen fibers, viscose, polyester fibers and hot-melt fibers, wherein the mass of the bamboo charcoal fibers is 25%-35%of the total mass of the spunlaced nonwoven filter material, the mass of the linen fibers is 15%-25% of the total mass of the spunlaced nonwoven filter material, the mass of the viscose is 5%-10% of the total mass of the spunlaced nonwoven filter material, the mass of the polyester fibers is 10%-30% of the total mass of the spunlaced nonwoven filter material, and the mass of the hot-melt fibers 5%-10% of the total mass of the spunlaced nonwoven filter material. The filter material is prepared from the hot-melt fibers, thereby having the higher stiffness and the better effect; meanwhile, the filter efficiency of the filter material is quite high, and the spunlaced nonwoven filter efficiency is improved to 99.995% from the original 20%-40%.

Description

technical field [0001] The invention relates to a filter material, in particular to a spunlace nonwoven fabric filter material and a weaving process thereof. Background technique [0002] At present, non-woven filter materials have been widely used in the field of gas and liquid filtration, among which, non-woven needle felt filter materials are the most widely used. [0003] The purification and dust removal filter materials currently used are generally needle-punched fiber felt and polyester spunbond materials. Needle-punched fiber felt has the following disadvantages: (1) The filtration accuracy is not high. The filtration accuracy of needle-punched materials is determined by the gap between fibers after the fibers are messy. At present, the fibers that can be processed by acupuncture are relatively thick. The resulting hole is relatively large. (2) The stiffness of the material is not good, so it cannot be used for folding processing, and can only be used for bag or be...

AI Technical Summary

Problems solved by technology

Needle-punched fiber felt has the following disadvantages: (1) The filtration accuracy is not high. The filtration accuracy of needle-punched materials is determined by the gap between fibers after the fibers are messy. At present, the fibers that can be processed by acupuncture are relatively thick. The resulting hole is larger

(2) The stiffness of the material is not good, so it cannot be used for folding processing, and can only be used for bag or belt filtration, which takes up a large space

(3) The quantification of the product is relatively high, generally 120g / m 2 The following products are difficult to produce

(4) The initial resistance of the material is large. Due to the limitation of the material processing technology, low-quantity products cannot be produced, and the fibers are closely arranged under the action of the mechanical force of the needle, forming a large initial resistance.

(5) The material cannot be blown back and cleaned, and the service life is not long

[0004] The disadvantages of polyester spunbond materials are: (1) The initial resistance of the material is relatively large

Because the material is reinforced with hot rollers, one-third of the holes in the material have been rolled into airtight points during the hot rolling process. (2) The filtration efficiency of the material is not high

The pores of this material are also formed through the gaps between the fibers after the fibers are messy. Since the fibers are relatively thick, the solid filtration efficiency is not high.
