Description
Technical field
The present invention relates to terylene preparation field, more particularly to a kind of preparation technology of high-efficiency polyester raw material.
Background technology
At present, PET material consumption when making beverage, the packing container such as food and film is very big, especially beverage bottle and
The consumption of mineral water bottle is annual, and all in cumulative year after year, used beverage bottle and mineral water bottle can cause substantial amounts of waste or used plastics,
And the natural degradation of plastics is very slow, more suitable for recycling, using waste or used plastics white vase piece production terylene be it is a kind of well
The method for solving waste or used plastics pollution, at present, the production technology for producing terylene using waste or used plastics white vase piece have been preliminarily formed,
For example, patent application publication number is high using discarded bottle chips production weaving for CN201210556714 patent application-one kind
The production technology of shelves core, the chopped fiber terylene resilience of existing production technology production is poor, during as clothes textile raw material,
Body surface feels not soft, uncomfortable when wearing, and is unfavorable for the market public praise of chopped fiber clothing, eventually influences waste or used plastics white vase
Piece produces the development of terylene, and prior art production polyester raw material inefficiency, and quality cannot be guaranteed.
The content of the invention
Special a kind of preparation technology of high-efficiency polyester raw material of offer of the invention, solves the polyester raw material that prior art is produced
Resilience is poor, produces polyester raw material inefficiency, the problem of quality cannot be guaranteed.
Technical scheme is as follows：
A kind of preparation technology of high-efficiency polyester raw material, comprises the following steps：
It is prepared by a, bottle piece：Using PET waste or used plastics, the different white vase piece of color is prepared；
B, the pretreatment of bottle piece：First bottle tablet raw material is cleaned, dried after cleaning with drier, then, according to need
Colour match is carried out to white vase piece and is mixed；
C, the melting of bottle piece：First the white vase piece matched is dried, then entered white vase piece feeding double screw extruder
Row melting；
D, filtering, homopolymerization, supercharging；Fused mass after to being extruded through extruder is filtered, and subsequently enters homopolymerization kettle
Viscosify and vacuumize removing small molecule, then by booster pump, with ensure spinning continuous production and melt pressure it is constant；
E, spinning, from booster pump come out after fused mass enter filament spinning component, by filament spinning component from spinneret spray,
F, wind into bucket：Tow after oil spout, is then wound and finally enters bucket by the oil injection agent on the tow of extrusion；
G, drawing-off：Tow in bucket is subjected to drawing-off；
H, nervous thermal finalization：The heating roller that the tow of drawing-off is sent into tension-setting machine, tension-setting machine is
Upper nine times eight and cross arrangement, tow are wound through all heating rollers, and heating roller is heated using steam, all heating rollers
Temperature according to tandem progressively be incremented by, maximum temperature be 200 degrees Celsius；
I, curling：The tow of winding is stretched, then loosened, tow is crimped naturally；
J, relaxation heat setting：Tow is subjected to hot-air seasoning；
K, cut-out packing：Product according to involved by tow is cut off and carried out to tow to the different demands of size
Enter bag packing.
In such scheme, the step a points are following steps：
A1, raw material are unpacked：First, bottle brick binding is cut, bottle brick then is put into unpacking pond carries out mechanical unpacking；
A2, impurity sorting：Stock bottle after unpacking is delivered in sorting belt by the conveyer belt with magnetic force, iron impurity quilt
Conveyer belt absorption is taken away, and workman sorts in sorting belt to the metal impurities without removal；
A3, a wash bottle：Stock bottle after sorting, which is transported in rinsing maching, to be cleaned, and rinsing maching is in cleaning stock bottle
While by stock bottle be moved to rinsing maching outlet；
A4, de- mark：De- mark is carried out to the stock bottle after cleaning with label removing machine to handle, separated bottle mark is sent by wind to be blown to back
Receive the stock bottle after case, de- mark and be transported to subsequent processing；
A5, secondary wash bottle：First, stock bottle is delivered into purge tank to be cleaned, is hot water and logical steaming in purge tank
Vapour, then stock bottle is taken out and is delivered to highly basic tank cleaned, and is the mixing liquid of sodium hydroxide and water in highly basic tank, most
Cleaned by purge tank again afterwards and be delivered to next step process；
A6, material and colour sorting：First, the artificial preliminary sorting for carrying out material, the stock bottle of non-PET materials is sorted
Remove, afterwards, material secondary sorting and colour sorting are carried out successively by the automatic sorting system of material and color, most institute at last
Need that the PET material stock bottles of color are sorted out and wind is delivered in feed bin；
A7, raw material are crushed and bottle cap separation：Stock bottle in feed bin is delivered into pulverizer to carry out at pulverization process, crushing
Reason forms bottle piece, and then bottle piece is delivered in tank, and the fragment of covering part is in floating shape, and the bottle piece of bottle portion sinks to water
In groove, finally the fragment of floating is got rid of, the bottle piece of submerged is delivered to next step process；
A8, the cleaning of bottle piece and dehydration：First bottle piece is cleaned with high-temperature water, then with added with sodium hydroxide and cleaning agent
Rinse water is cleaned to bottle piece, and cleaning carries out drying dehydration with drier after finishing, after dehydration is finished, with normal-temperature water to bottle piece
Cleaned, cleaning carries out drying dehydration with drier to bottle piece again after finishing, and production textile raw material can be carried out by eventually forming
White vase piece.
In such scheme, the temperature of hot water is 85~95 degrees Celsius in the purge tank in described a5 steps, in highly basic tank
Sodium hydroxide shared by weight percentage be 3.6~4.1%.
In such scheme, in described step b, white vase piece color proportioning is used in production cloth or home textile and its filler
Chopped fiber when using blueness and white white vase piece mixing match, blue white vase piece accounts for 14%~
19%, when producing the chopped fiber used in toy filler using the white vase piece mixing match of other colors.
5th, the preparation technology of a kind of high-efficiency polyester raw material according to claim 1, it is characterised in that：Described step
In c, the operating temperature of double screw extruder is 270~290 degrees Celsius.
In such scheme, pressure is less than or equal to pressure constant in 16Mpa, filter process before the filter during step d filterings
Power is 8.5Mpa, and double-filtration is used when filtering, and the screen pack of filter device therefor is 15 microns, two grades when the first order is filtered
The screen pack for filtering filter device therefor is 25 microns.
In summary, the beneficial effects of the invention are as follows：
1st, the chopped fiber using the production of PET waste or used plastics is corrosion-resistant, nonhygroscopic, and service life is longer, the bottle of preparation technology
Piece pretreatment stage, bottle piece is divided into three major types according to white, blueness and other colors, is carried out according to the purposes of produced terylene
Color is matched, and so the waste or used plastics of a variety of colors can be made fully to be applied, so as to avoid the pollution of certain plastic bottle
And waste, it is of the invention that nervous thermal finalization is set between drawing-off and curling, and multiple heating rollers are provided with to tow heating,
So that the heating-up temperature of tow is in gradual rise, it is to avoid because heating roller is few, the too quickly silk caused of heating-up temperature rise
The situation that beam toughness is not enough, resilience is poor.
