Description
Technical field
The present invention relates to chemical fibre preparing technical fields, and in particular to a kind of filter regeneration system of waste and old non-woven cloth
System.
Background technology
It is well known that China is textile industry big country, while being also that textile consumes big country, annual China's waste textile
Up to tens million of tons.Wherein, terylene, also known as polyester fiber (polyester, abbreviation PET), polyester (PET) are to benzene two
Formic acid and ethylene glycol carry out the polymer of the stabilization of polymerization generation, and molecular structure high degree of symmetry has certain crystalline orientation
Ability, thus with higher film forming and become second nature, and have non-biodegradable, it is widely used in packaging, weaves, outside electronic apparatus
Shell etc. field, therefore, dacron occupy sizable proportion in waste textile, but existing terylene waste material is several
It is all taken as rubbish to be buried and burned, destruction is caused to environment, reuse ratio is extremely low.Wherein, PP plastics (poly- third
Alkene) be the another fine resin kind developed after the nylon, it be a kind of high density, unprotected side chain, it is highly crystalline must linear gather
Object is closed, there is excellent comprehensive performance, the at present production of polypropylene fibre to be roughly divided into two kinds, one of which is to make raw material through poly- by propylene
It closes, and to its material modification, melt spinning, spinning melt filtering, quenching, winding, obtained fiber, but third produced
Synthetic fibre silk low strength；Another kind is to use acrylic resin for raw material, spinning moulding, is then carried out in spindle type traction twisting mill
Two-stage is drawn and twisting, and high-strength polypropylene filament is made.Part manufacturer produces polypropylene fibre by recycling waste PP plastics at present, raw
Production. art includes the production process of waste PP production polypropylene fibre：Regeneration particle-dispensing-stirring-drying-feed intake-screw rod melt
Melt-filter-spinning-cooling-oils-drawing-off-winding-classification-packaging.Therefore it is given birth at present using waste PP plastics
When producing polypropylene staple fibre spun yarn, need first to be added at the regeneration particle that can be used for producing polypropylene staple fibre spun yarn, then by regeneration particle by waste PP plastic processing
For work at polypropylene staple fibre spun yarn, production process is more various.
Since terephthalic acid (TPA), propylene are both needed to refine processing from oil, and oil belongs to non-renewable precious resources,
Therefore above-mentioned finished product is higher using new PET material, PP material manufacturing costs, and is unfavorable for energy conservation.Therefore, how by reasonable
Effective method enables waste and old terylene fabric, polypropylene fabric renewable resources at pendulum problem anxious to be resolved in face of us,
Now it is badly in need of a kind of equipment or technical matters that will all can be reprocessed after the recycling of waste textiles cloth.
Currently, domestic have non-biodegradable using PET kind polyester substances, the Ke Xunhuanliyong existing skills of PET are developed
Art, for example, using PET spun-bonded hot rolling non-woven fabric techniques, but present PET substances processing and recovery and utilization technology need
In development and improve.Wherein：
Notification number provides one kind for the patent of invention of 102605455 B of CN and is washed by recycled PET bottles sheet stock large-scale production
The PET bottle of recycling is crushed slabbing, is dried after cleaning by the method for synthetic fibre FDY filament, is then fed into and crystallizing bed is tied in vivo
Crystalline substance, then be dried, the bottle chips after drying enter screw extruder and carry out melt extruded, and the melt by filtering enters homogenizing
Kettle carries out polycondensation reaction in 1.4-1.5 hours, and melt is made to be homogenized in homogenizing kettle, and the melt after homogenizing enters manifold, uses
High-speed spinning process carries out spinning, and polyester FDY long filament is made.This production method increases homogenization step, solves polyester bottles
Sheet stock melt viscosity fluctuates big, stability difference problem, realizes using recycled PET bottles sheet stock as raw material, continuous, large-scale production terylene
FDY filament product.
Notification number for the patent of invention of 105177743 A of CN provide it is a kind of using regenerative piece of polyester bottle produce fine-denier and
The method of the flat recycled polyester long filament of micro Denier, steps are as follows：1) the discarded regenerative polyester bottle of recycling is pre-processed to obtain
Polyester bottle slice；2) pretreated polyester bottle slice is handled by low-temperature vacuum drying；3) successively by dried polyester bottle slice
Homopolymerization kettle, secondary filtration, metering pump, spinning manifold, filament spinning component, ring are glued by screw rod melt extruded, primary filter, liquid phase tune
Quenching, boundling oil, drafting forming and winding doffing, obtains finished product.
Notification number provides one kind for the patent of invention of 105525375 A of CN and prepares polyester staple fibers by waste and old polyester fiber
The method of dimension is that first the useless cloth of the polyester by recycling, the useless fiber of polyester or polyester useless slurry block are introduced into crusher, is introduced after broken
Compaction apparatus water removal compacting obtains the dry polyester waste material that moisture content is less than 200PPm, then dry polyester waste material is fed Screw Extrusion
Machine melting extrusion, while the lower-molecular substance brought into removal raw material is vacuumized, by the melt of screw extruder extrusion through filtering,
Manifold is introduced by metering pump afterwards and carries out melt spinning, the strand sprayed by spinneret cures through ring wind quenching, on strand
Strand is assembled tow and falls bucket, obtains as-spun fibre by oil；As-spun fibre is assembled into tow through creel, then through seal wire
Machine imports drafting system drawing-off, goes out drafting system and obtains drafting silk, most afterwards through curling, drying, laxation shaping, cut-out and packing,
Obtain finished product.
Notification number is a kind of direct spinning process for regenerated polypropylenes that the patent of invention of 102154718 B of CN provides, including following step
Suddenly：A, pre-treatment：Waste PP plastics are chosen, tears up and carries out flotation, cleaning, the waste PP plastics cleaned up are taken off
Water；B, the production of polypropylene fibre：Dewatered waste PP plastics are measured in proportion, and compacting plasticizing melts, and true by vacuum pumping
Then sky is filtered by filter device, filtered waste PP plastics are carried out spinning and cooling；C, it post-processes：After cooling
Silk oil and drawing-off.The direct spinning process for regenerated polypropylenes process is simple, while waste PP plastics rationally are utilized, and reduction is produced into
This, also avoids waste PP plastic pollution environment.
However, aforementioned cleaned using waste and old polyester or waste and old polypropylene, recrystallize regeneration or utilization in the prior art
It is homogenized kettle and reworked material is formed to waste and old polyester tune viscosity, and prepare polyester fiber or polypropylene fiber, but waste and old polyester or waste and old
Polypropylene contains or is stained with a large amount of pollutants for being difficult to clean removal, and such as spot even impurity, and these pollutants are on the one hand
Polymer molecular weight and its distribution are influenced, to influence the viscosity of melt and the stability of melt, on the other hand, spinning can be caused
The elongation at break of fiber product, fracture strength etc. afterwards, and waste and old polyester, waste and old polypropylene material can not be solved in the prior art
The problem of effective filtering of middle impurity or pollutant, it is even more impossible to solve how in virgin material high additive waste and old polyester or waste and old poly- third
The technical issues of alkene reworked material.
