Description
Technical field
The present invention relates to regrown material technical field, specially a kind of regenerated silk processing and treating method.
Background technology
Regenerated silk is also known as regenerated fiber, and regenerated fiber is using short containing the high molecular substance of native cellulose such as cotton
Fiber made of suede, timber, reed etc., it is possible to use the raw material containing protein manufactures regenerated fiber.Regenerated celulose fibre,
Include mainly viscose rayon, copper ammonia fiber and acetate fiber.Azlon includes mainly caseinate, fibroin fiber
And soybean protein fibre, yield is considerably less, and regenerated silk mainly adds there are three flow recycled polyester carrying out regeneration processing
Work production procedure, it is super have that photo reversal slice flow, EG kettles are residual and purification EG recycles processing flow, regenerated silk is produced at present
For a kind of trend, and the production method of traditional raw silk is complicated, it is difficult to operate, thus it is proposed that a kind of regenerated silk working process
Method.
Invention content
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of regenerated silk processing and treating method
Problem.
To achieve the above object, the present invention provides the following technical solutions：A kind of regenerated silk processing and treating method, it is specific to walk
Suddenly it is：
(1) useless cloth is collected and is classified in treatment box, carry out degumming pretreatment, added into treatment box after processing
Enter after being dissolved in the organic solvent of low concentration of salt, then by treated, material is filtered by filter device, is filtered out and is not required to
The impurity wanted；
(2) filtered material is poured into blender, low speed crushing, stirring, stirring is carried out to material by blender
Material is poured into drying unit afterwards, material, which is carried out high-temperature heating, by drying unit makes its thawing；
(3) material after thawing is poured by conduit in reaction kettle and carries out alcoholysis reaction, by catalyst, EG is added
To ester exchange reaction is carried out in reaction kettle, prepolymer BHET is obtained, prepolymer BHET is poured into collecting box, BHET is sent into
Polymeric kettle carries out polymerisation generation PET and obtains final products；
(4) the prepolymer BHET in collecting box is poured into accurate filter, is filtered, and the mistake on accurate filter
Filter opening is 30 to 50 microns, and PET solutions are obtained after prepolymer BHET is filtered, are then placed into PET melt cold
But in device, cooling, pelletizing is carried out, be packaged to be surpassing has photo reversal slice；
(5) when carrying out useless cloth and being processed since chemical reaction can produce exhaust gas, treatment box, blender,
It is both provided with asepwirator pump at the top of the position of reaction kettle and accurate filter, and asepwirator pump is each equipped with large-scale gas collecting jar with ground-on cover plate.
Preferably, the low concentration of salt in step (1) is calcium thiocyanate and calcium thiocyanate and useless cloth ratio is 1:1.5.
Preferably, suitable water need to be added when step (2) crushing, stirring gives up cloth, and the ratio of water and useless cloth is 1:100.
Preferably, the drying unit in step (3) is made of two groups of high-temperature dryers, and two groups of high-temperature dryers
Maximum temperature is 550 degree.
Preferably, the proportioning of the catalyst in step (3) and EG are 130-135kg：7-8 tons.
Compared with prior art, the beneficial effects of the invention are as follows：
The regenerated silk processing and treating method, it is easy to operate, it is easy to use, useless cloth is fabricated to graininess, is solved over
The problem of useless cloth can not convey has been truly realized the environmental protection concept that waste and old clothes can be used as raw material, this be Physical again
The thing that raw technique is not accomplished eliminates personal safety hidden danger since material production line carries out in closed production line,
Because of oneself production material, the production stocked up from useless cloth to material has foreign matter sorting, ensure that the quality of material, avoids gold
Belong to being mixed into for impurity, the production process of material meets environmental requirement, exhaust gas centralized processing orderly discharge.
Specific implementation mode
