Abstract
The invention provides a preparation method of non-woven fabric filter material by combining spunlaid with water jet flow consolidation. The steps of the method include drying polyester chip crystal, spinning by screw extruding, cooling by later blow, air current drawing, separation cross laying, winding solidifying by high-pressure cut squirt jetting, drying, rolling and unrolling, traditional or functionalization post-processing, edge cutting, winding and finishing. The invention has the advantages of stable structure, high intensity, even surface, soft hand-feeling, uniform pore diameter distribution and good filtering performance.
Description
Technical field
The present invention relates to a kind of preparation method of non-woven filter material, the preparation method of the non-woven filter material that particularly a kind of filature fleece formation combines with water fluid jet reinforce.
Background technology
At present, non-woven material adopts filature fleece formation and acupuncture fixed, has that intensity is low, strainability is poor.
Summary of the invention
Technical problem of the present invention is the preparation method that the non-woven filter material that a kind of strainability is good, intensity is high filature fleece formation combines with water fluid jet reinforce will be provided.
In order to solve above technical problem, the invention provides the preparation method of the non-woven filter material that a kind of filature fleece formation combines with water fluid jet reinforce, this preparation method comprises the steps:
1) polyester slice crystallizing and drying;
2) extrusion spinning by screw press;
3) cross air blasting cooling;
4) air drawing;
5) divide the silk lapping;
6) high pressure liquid drugs injection jet tangles and reinforces;
7) oven dry;
8) reel;
9) debatching;
10) conventional post processing or functionalization post processing;
11) cut edge, reel;
12) finished product.
Conventional post processing comprises the steps:
1) thermal finalization;
2) singe;
3) calendering.
The functionalization post processing comprises the steps:
1) semi-finished product impregnated in the chemical treatment reagent;
2) preliminary drying;
3) bake;
4) thermal finalization;
5) cut edge;
6) reel;
7) finished product.
Superior effect of the present invention is:
1) non-woven filter material that makes the long filament in the fibre web tangle mutually and form after the multiple tracks puncture oven dry of spun-bonded continuous yarn by high-pressure water jet, have soft, surface smoothness good, than having more higher intensity with the fixed non-woven filter material of acupuncture;
2) the present invention uses the division long filament to make spun-bonded continuous yarn, water jet process plays the effect of division long filament, opening fine rate reaches more than 70%, obtain the long filament fibre web of diameter less than 0.01dtex, ultra-fine or the fine long filament that accounts for the fiber total amount overwhelming majority has formed the three-dimensional structure finer and close, more mixed and disorderly than common synthetic fibers in spunlace non-woven material, have more fine voids, increased the strainability of non-woven filter material greatly;
3) grammes per square metre of this non-woven filter material is at 100～600g/m
2Between, can satisfy different clients' demand.
The specific embodiment
The invention provides the preparation method of the non-woven filter material that a kind of filature fleece formation combines with water fluid jet reinforce, this preparation method comprises the steps:
1) polyester slice crystallizing and drying;
2) extrusion spinning by screw press;
3) cross air blasting cooling;
4) air drawing;
5) divide the silk lapping;
6) high pressure liquid drugs injection jet tangles and reinforces;
7) oven dry;
8) reel;
9) debatching;
10) conventional post processing or functionalization post processing;
11) cut edge, reel;
12) finished product.
Wherein, the filature fleece formation step is that the raw material polyester slice is sent into screw extruder behind crystallizing and drying, after fusion, extruding, filtration, metering, spray by spinneret orifice, the long filament tow evenly is laid in and coagulates on the lace curtaining after air-flow cooling drawing-off, forms the long filament fibre web.
Water thorn step is at first to be admitted to water thorn district by the spun long filament fibre web of polyester slice to carry out the pre-humidifying processing, prewet and make fibre web tightr, get rid of the air in the fibre web, make fibre web can more effectively absorb the liquid drugs injection energy, strengthen the entanglement effect of fiber in the water thorn process.Fibre web after prewetting is sent to rotary drum water thorn district by defeated lace curtaining and carries out high-pressure water jet entanglement reinforcing, and after No. six liquid drugs injection acupuncture, fibre web has obtained further reinforcing, and Stability Analysis of Structures is effectively tangled between the fiber.The water jet process parameter is shown in Table 1:
Table 1
| Water jet quantity | Pump quantity | Water jet place pressure (crust) | Water needle plate | Electric weight KW |
| 6 | 6 | 90～340 | 0.10～40 | 250/ pump |
Conventional post processing comprises the steps:
1) thermal finalization;
2) singe;
3) calendering.
Wherein the technological parameter of thermal finalization is shown in Table 2:
Table 2
| Speed m/min | Temperature ℃ | Time min | |
| Thermal finalization | 6～8 | 210～250 | 6～10 |
The technological parameter of hot rolling is shown in Table 3:

| Last central roll spacing mm | Middle lower roll spacing mm | Last roll temperature ℃ | In roll temperature ℃ | Following roll temperature ℃ | Speed m/min |
| 2～3 | 2～3 | 200 | 180 | 180 | 18～25 |
The functionalization post processing is that this non-woven filter material carries out the processing of various functionalization according to client's different needs, as refuses the anti-oil processing of water, PTFE impregnation process, graphite treatment, flame treatment etc., comprises the steps:
1) semi-finished product impregnated in the chemical treatment reagent;
2) preliminary drying;
3) bake;
4) thermal finalization;
5) cut edge;
6) reel;
7) finished product.
The chemical assistant prescription of functionalization post processing is shown in Table 4.
Table 4
| The title of functionalization post processing | Reagent name | Matched proportion density % |
| Refuse the anti-oil processing of water | Refuse water oil-proofing agent AC-7500 | 6 |
| The PTFE impregnation process | The PTFE emulsion | 10～20 |
| Flame treatment | Fire retardant | 30 |
| Graphite treatment | The graphite emulsion | 5～6 |
This non-woven filter material is after post processing, and Stability Analysis of Structures, intensity height, surfacing, soft, even aperture distribution can be widely used in the production of waterproof roll.
