Abstract
A method of asphalt water-proof coiled material needle-punched geotextiles are prepared by raw material of polyester bottle slice, it is mainly: polyester bottle slice enters extruder after pre-crystallized and is dry and squeezes out, the reworked material melt after being filtered mix in the duct after together into reactor.Melt passes through the processes such as hydrolysis, alcoholysis, homogenizing, decontamination reaggregation, final viscosity is homogenized and stable polyester fondant, then it filters through booster pump pressurization, filter again and is sprayed into filament through measuring from spinneret into spinning machine, by side-blown air cooling, through sub-wire, pendulum wire after tubular type air drawing, uniform web is formed on lapper, and fibre web output is sent to needing machine carries out needle thorn consolidation, cutting is wound, asphalt water-proof coiled material needle-punched geotextiles are made.The present invention, as raw material, can not only be recycled waste polyester bottle chip using waste polyester bottle chip, but also be conducive to energy saving, the production cost of reduction asphalt water-proof coiled material needle-punched geotextiles.
Description
Technical field
The present invention relates to a kind of preparation method of chemical fibre nonwoven products, especially production asphalt water-proof coiled materials to pierce soil with needle
The preparation method of work cloth.
Background technique
For China's asphalt water-proof coiled material tire base fabric used at present mainly based on short polyester tire, short polyester tire is with poly-
Non-woven cloth is made by shredding mixing, combing (or gas comb) networking, cross lapping, drawing-off and needle thorn consolidation in ester staple fiber, then
Through sizing, impregnation, drying and be made.But since it haves the defects that in many performances, developed countries do not use substantially
Or it is few using as modified asphalt waterproof coiled material tire base.With advances in technology, use has also been developed in recent years, China
Polyester filament tire base fabric is the asphalt water-proof coiled material of base tire, and raw material is polyester slice.But it is not only wasted to be disposable
Resource pollutes environment, and cost is also higher.
Using polyester bottle slice as raw material, produce long filament POY, the technique of FDY is mature, the country also use polyester bottle slice for
Raw material produces the introduction of polyester geotex-tile or spun-bonded hot rolling non-woven fabric, but since waterproof coiled material tyre base is non-with terylene spun-bonded needle thorn
Some particular/special requirements of woven cloths use current production method and technique that can't produce pitch using polyester bottle slice as raw material anti-
Water coiled material needle-punched geotextiles.
Summary of the invention
The purpose of the present invention is to provide one kind to prepare asphalt water-proof coiled material needle-punched geotextiles by raw material of polyester bottle slice
Method.
The present invention is mainly that raw material prepares asphalt water-proof coiled material needle as raw material substitution with polyester (PET) using polyester bottle slice
The method for piercing geotextiles, therefore concrete operations of the invention are substantially same as the prior art, only because raw material changes some operations
It is also changed correspondingly with parameter.
Method main contents of the invention are as follows:
1, the present invention is, first by its pre-crystallized and drying, to make dry bottle piece moisture content control using the polyester bottle slice of recycling as raw material
System is in≤50PPM.
2, polyester bottles bottle piece is put into after extruder melting extrusion and enters filter, filtering accuracy is 50 μ.
3, the reworked material melt after being filtered enters reactor after mixing in the duct together.Melt passes through water
The processes such as solution, alcoholysis, homogenizing, decontamination reaggregation, final viscosity obtain viscosity-adjusting agent to 0.70~0.80 ± 0.01dl/g it
Between be homogenized and stable polyester fondant, then again through booster pump pressurization and filter filter into spinning machine, filtering accuracy 25
μ。
4, pump-metered is measured, is sprayed into filament from spinneret, the revolving speed by controlling metering pump controls the list of polyester filament
Silk size is 2~4dpf.
5, polyester filament is by side-blown air cooling, through sub-wire, pendulum wire after tubular type air drawing, is formed on lapper uniform
Fibre web output is sent to needing machine carries out needle thorn consolidation, cutting is wound, asphalt water-proof coiled material needle thorn geotechnique is made by web
Cloth.
The invention has the following advantages over the prior art:
1, using waste polyester bottle chip as raw material, waste polyester bottle chip can not only be recycled, but also be conducive to
It is energy saving, reduce the production cost of asphalt water-proof coiled material needle-punched geotextiles.
2, using asphalt water-proof coiled material needle-punched geotextiles produced by the invention, product performance index with use polyester for
In the identical situation of geotextiles performance indicator of raw material, production cost can reduce by 500~600 yuan/ton or so.
