Amount percent is respectively：Natural ramie fiber accounts for 20%-100%；Chemical fibre accounts for 0%-80%, by fiber opening → combing →
Fleece laying → acupuncture → rear finishing process is obtained novel green airfelt.
Described natural ramie fiber includes one or more of Boehmeria, noil, Corchorus olitorius L., kenaf etc.；Described chemistry is fine
Dimension includes one or more of polyester staple fibers, nylon staple, aramid fiber short fibre etc..
The parameter of described airfelt is：Thickness is 1.5-7mm, and grammes per square metre is 100-350g/m2, air penetrability is 350-3000L/
m2S, ultimate strength is 3-350N, and elongation at break is 20-110%.
The method preparing composite molding green airfelt is as follows：
Described fiber opening is to carry out independent shredding to natural ramie fiber and chemical fibre respectively first, then press again
Mix shredding according to ratio；
Described carding process is that the natural ramie fiber of mixing shredding and chemical fibre are sent to combing in carding machine, warp
Cross angle stripper in carding machine, composite fibre is carded to single layer fibre net by cylinder, the effect of doffer, the feeding frequency of carding machine is
1-30Hz, cylinder rotational frequency is 10-30Hz, and doffer's rotational frequency is 5-25Hz；
Described fleece lay-up process is to hand over the single layer fibre net of carding machine combing through lapping machine according to use requirement
Fork is folded into thick net, and fourth curtain frequency is 2-5Hz；
Described needling process is to be sequentially sent to pre-needling machine, main needing machine by intersecting the fiber thickness net being paved into, make through acupuncture
With being consolidated into fiber felt, pricker bestock is 1000-5000 piece/m；Punch frequency is 400-500 time/min；Depth of needling is
2-10mm；Acupuncture pass is 1-3 time.
Compared with prior art, being mainly characterized by of the present invention：The present invention adopt natural ramie fiber or natural ramie fiber with
Chemical fibre mixes, and natural ramie fiber accounts for 20%-100% with the mass percent of chemical fibre for natural ramie fiber；Chemistry is fine
Dimension accounts for 0%-80%, feeds the technological parameters such as frequency, punch frequency, depth of needling, acupuncture pass by adjusting carding machine, makes fibre
Consolidate between dimension, be in three-dimensional space structure in airfelt it is ensured that the good mechanical property of airfelt and permeability, with mesh
The chemical fibre of front use is compared and especially is remained to keep good permeability at high temperature under high pressure.Finally give a kind of molding work
Skill is good, the flaxen fiber airfelt close with conventional chemical fibre airfelt such as breathability, mechanical property, to substitute chemistry fibre
Dimension airfelt.
The present invention adopts flaxen fiber to substitute conventional chemical fibre, by adjusting the compound of the techniques such as combing, acupuncture preparation
Compared with existing chemistry polyester fiber airfelt, ultimate strength improves about 40% to material molding green airfelt, and air penetrability carries
High by about 20%, High Temperature High Pressure permeability is significantly better than chemical fibre airfelt, and moulding process is good.The method preparation is produced
Product raw material environmental protection, product easily recycles after discarding, and the prices of raw materials are cheap simultaneously, can effectively reduce composite
The holistic cost of product processing, is conducive to composite popularization and application.
