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

A kind of hydro-entangled non woven fabric filter material and its weaving process
Technical field
The present invention relates to a kind of filtering material is and in particular to a kind of hydro-entangled non woven fabric filter material and its weaving process.
Background technology
At present, non-woven filter material has been widely used in the filtration art such as gas and liquid, wherein, non-woven pin Thorn felt filtering material application is at most.
The purifying and dedusting filtering material currently using is usually needling fiber felt and terylene spun-bonded bi-material.Needling fiber Felt has a disadvantage that：（1）The precision filtering is not high, the filtering accuracy of needling material by fiber mixed and disorderly after between fiber between Gap determines, the fiber that current acupuncture can be processed all compares slightly, and the hole producing therefrom is also just than larger.（2）Material very Degree is bad to be only used for pocket type or belt type filter it is impossible to process for folding, and takies larger space.（3）The quantitation of product is relatively Height, typically quantitative 120g/m2Following product is difficult to produce.（4）The initial resistance of material is big, and the processing technique because of material is limited System, the product of light basis weight can not produce, and fiber very close-packed arrays in the presence of pricker mechanical force, forms larger initial resistance Power.（5）This material can not carry out reverse gas cleaning, and service life is not long.Because the diameter base of dust particle during filtering This is all much smaller than the aperture on needling material surface, and when filtering, the inside of this material that a lot of dusts enter, works as resistance When carrying out blowback with reciprocal wind when reaching to a certain degree, particle is stuck in the inside and can not produce by boasting.
The shortcoming of terylene spun-bonded material has：（1）The filtration initial resistance of this material is larger.Because this material is to prick roller using heat Reinforced, during heat is pricked, the hole of 1/3rd material is pricked roller by heat and is bundled into air-locked point（2）Material mistake Filter is inefficient.The hole of this material be also by fiber after mixed and disorderly for the fiber between the hole that formed of gap, due to fiber all It is that comparison is thick, Gu filter efficiency is not high.
Content of the invention
Present invention aims to the deficiencies in the prior art, now provide that a kind of pore size filter is little, filter effect is good Hydro-entangled non woven fabric filter material and its weaving process.
For solving above-mentioned technical problem, the technical solution used in the present invention is：A kind of hydro-entangled non woven fabric filter material, its Innovative point is：Formed by the weaving of bamboo carbon fiber, flax fiber, viscose rayon, polyster fibre and hot-melt fiber, described bamboo charcoal is fine The quality of dimension accounts for the 25-35% of hydro-entangled non woven fabric filter material gross mass, and the quality of described flax fiber accounts for hydro-entangled non-woven fabric The 15-55% of filtering material gross mass, the quality of described viscose rayon accounts for the 5-10% of hydro-entangled non woven fabric filter material gross mass, The quality of described polyster fibre accounts for the 10-30% of hydro-entangled non woven fabric filter material gross mass, and the quality of described hot-melt fiber accounts for water The 5-10% of spunlaced nonwoven filtering material gross mass.
Another object of the present invention is to disclose a kind of hydro-entangled non woven fabric filter material weaving process, and its innovative point exists In：By bamboo carbon fiber, flax fiber, viscose rayon, polyster fibre and hot-melt fiber through pre- shredding, smart shredding, mixing, feed in advance Carry out spun lacing after material, combing, lapping and draft process, prepare hydro-entangled non-woven fabric, whole after hydro-entangled non-woven fabric is carried out Science and engineering skill, completes hydro-entangled non woven fabric filter material weaving process；Described postfinishing process comprises the following steps that：
（1）Dipping：Hydro-entangled non-woven fabric is immersed in impregnation liquid, described dip time is 4-12 hour；
（2）Pressure rolling：Pressure rolling is carried out on applicator roll, the pressure of described applicator roll is 2-12kg；
（3）Dry：Then carry out drying process in drying case, described drying temperature is 90-180 DEG C, described criteria thus the drying time is 2-4min.
Further, described step（1）In impregnation liquid be acrylic compounds sizing material, phenolic resin, benzene one acrylic emulsion, chlorine one One of vinegar milk liquid and politef.
Beneficial effects of the present invention are as follows：
（1）The present invention uses high ventilative spun lacing material, and through postfinishing process, so that the present invention is prepared into The filtration initial resistance of the filtering material arriving is smaller, can reverse gas cleaning, the Kong Ji of the filtering material that the present invention prepares This is all little than dust, so when filtering, dust is blocked on the surface of filtering material, below reciprocal wind action power Can will be produced by boasting and be collected by the deashing filtering on film surface, long service life.
（2）The raw material of the present invention employs hot-melt fiber and is prepared from, thus possessing higher deflection, effect is relatively Good, the filter efficiency of the present invention is very high simultaneously, and the filter efficiency of original hydro-entangled non-woven fabric 20-40% is brought up to 99.995%.
