Description
Technical field
It is more particularly to a kind of to utilize waste and old polyester fiber production fiber the present invention relates to a kind of production method of polyester fiber
The method of long filament.
Background technology
In the prior art, there are a kind of preparation method of Regenerated Polyester Fibres, its application number：201410608104.0；Application
Day：2014-11-03, publication number：104357938A；Publication date:2015-02-18；This method is used for the chemistry of waste and old polyester again
Raw field, using the binary titanium alkoxide alkali metal coordination compound for being dissolvable in water ethylene glycol as catalyst, it is catalyzed waste and old polyester system
The ethylene glycol depolymerization of product and the polymerization process again of depolymerization product, this catalyst for the ethylene glycol depolymerization of polyester and depolymerization product again
Polymerization process has higher catalytic activity, therefore in the preparation method of this Regenerated Polyester Fibres, prepares Regenerated Polyester Fibres
Process can be used for polycondensation again without catalyst is removed from depolymerization product, can save the same of depolymerization product separating-purifying cost
When ensure that recycled polyester quality, the color and luster and intensity of Regenerated Polyester Fibres can be obviously improved, be waste and old polyester product it is continuous
Change closed loop recovery and provide possibility.
It is disadvantageous in that：Regenerated Polyester Fibres are produced, it is necessary to carry out depolymerization after being heated into melt, so by this method
Carry out polycondensation again afterwards, this hair process adds energy consumption.Itself main reason is that, waste and old polyester material, in its production process
Some polyester decomposes, and in use, ingress of air rear oxidation, will also result in the fracture of part key so that polyester
It is molecular weight polymerized uneven, reduce spinning properties.
The content of the invention
, can be in low energy it is an object of the invention to provide a kind of method that dyeing tubular filament is produced using recycled polyester
Regenerated Polyester Fibres are produced in the case of consumption.
The object of the present invention is achieved like this：A kind of method that dyeing tubular filament is produced using recycled polyester, including
Following steps：
1）The preparation of regenerative raw materials：Waste and old polyester is shredded, trifle in the world is removed after being washed, then by centrifugal dehydration, Ran Hou
50-75 DEG C of heated-air drying 20-40 minute；
2）Dried regenerative raw materials are crushed to regeneration master batch by screw extruder；
3）Will regeneration master batch under vacuum conditions, be sent into solid-phase tack producing device, in 160-180 DEG C, vacuum 100-800Pa,
The thickening time is 5-8 hours；
4）Material after thickening is mixed with Masterbatch and is sent into screw extruder progress batch mixing extruding；
5）The coloring blend melt extruded from screw extruder is subjected to spinning through hollow spinneret plate, obtains tubular filament；
6）Cool down blowing under nitrogen protection to spinning；
7）Using oil nozzle to spin finishing；
8）Multiply spinning is subjected to network processes by network nozzle；
9）Wind into storehouse.
It is as a further improvement on the present invention, the circle of the hollow spinneret plate exits channel angle as 55-65 °.
It is as a further improvement on the present invention, the step 6）In, nitrogen is carried out secondary cold by aerial cooler
But after handling, then cooling blowing is carried out to spinning.
It is as a further improvement on the present invention, the step 5）The degree of hollowness of the tubular filament of middle acquisition is 15-
28%。
In the present invention by the way of solid-phase tack producing so that polymer under solid state shape, small molecule energy continuous polymerization into
Macromolecular, the small molecule produced in polymerisation can be excluded by vavuum pump so that and it polymerize to direction and develops, by
It is also reversible reaction in itself in polymerisation, polymerization-decomposition can ensure that polymerisation is relatively equal in lasting progress, solid-phase tack producing
It is even, so that the mean molecule quantity of polyester is evenly distributed, and then make it that spinning properties are more preferable, the polyester fiber intensity of acquisition
Height, it is not easy to break.Spinning is cooled down under nitrogen protection, it is ensured that spinning when temperature is of a relatively high, will not with air
Oxygen occur oxidation reaction, further ensure spinning properties.This method can be used for getting a foothold various waste and old beverage bottles, weaving
Material carries out regeneration treatment, not only environmentally friendly, and energy consumption is relatively low.
