Description
Technical field
The present invention relates to belong to cycling and reutilization fibre technology field, particularly relate to a kind of with Pillar recovery as raw material production
Dual-component parallel composite fiber.
Background technology
At present, on China's chemical fibre market, more than 80% product belongs to differentiated product, but owing to homogeneity is serious, enterprise is also
Do not benefit from it because of the differentiation of product, but cause its existence more difficult, especially because of the competition of the differential raw material brought
Use the filling fiber that Three-dimensional crimped hollow polyester staple fiber is representative that unsymmetrical excavation Technology produces.Use at a high speed
It is fiber fiber in cooling procedure that the unsymmetrical excavation of low temperature produces the moulding mechanism of Three-dimensional crimped hollow polyester staple fiber
Windward side makes it produce certain stress difference with lee face because rate of cooling is different, and in fiber last handling process, fiber passes through
The stress of stretching fiber is released, thus forms curling.
Due to unsymmetrical excavation moulding mechanism determine its to raw material and the requirement of spinneret hole shape, want to keep three-dimensional volume
The lasting compression rebound that bent hollow pet staple fiber is good must control the degree of hollowness (22%～35%) of fiber well, for thick denier
Wanting to keep good curling must have higher melt viscosity (>=0.665dl/g) with fine-denier, too high viscosity requirement is then
It is requirement higher to raw material.And if only from the angle of curling, curling can be realized by improving the degree of hollowness of fiber
The production of good fiber, but when hollowness of fibre more than 40% and above time, owing to the wall of fiber core is thinning, fiber self is held
The anti-surrender ability being subject to gradually weakens, and fiber is easy to be flattened under external force, thus causes the elasticity of fiber with persistently
The elasticity of compression is lost.From the point of view of situation about understanding in industry, in industry, the fiber of more than 90% there is problems in that.
And composite spinning is by two kinds of fiber-forming polymers side by side, utilizes the difference of its kind, viscosity or proportioning, pass through respectively
Respective melt pipe, is having the composite component how soon distribution plate combines to be allocated, from same spray after arrival spinneret
Silk sprays fibroblast in the air.Unsymmetrical excavation Technology produce Three-dimensional crimped hollow polyster fibre compared with composite spinning arranged side by side its
Principle is essentially identical, unique unlike single melt (homopolymer) fiber by the molecule whereabouts company part different with crystalline texture
Being composited, parallel composite fiber is then chemical constitution or different two components of molecular weight are composited.This point is little just
Little difference causes the production technology of two kinds of fibers and technology to there is huge difference, also exists because this point difference creates product
There is certain difference in performance and production cost.
Summary of the invention
The process conditions producing the existence of three-dimensional hollow polyester staple fiber product for asymmetric techniques are harsh, to ingredient requirement
High, the problem of the elastic restoration ratio elasticity of compression low, lasting difference.The invention aims to provide a kind of with Pillar recovery raw material system
Standby dual-component parallel composite fiber realizes the low-cost production of highly elastic fiber.
In order to achieve the above object, present invention employs following technical scheme:
A kind of dual-component parallel composite fiber prepared with Pillar recovery raw material, the preparation method of this composite fibre include with
Under step:
1) Pillar recovery raw material is dried；
2) dried polyester respectively enters two groups of screw extruders, and after screw rod is melted, first via melt is through cascade filtration
Entering spinning manifold after device, the second road melt enters after single filter that the quenched tune of liquid phase is adhesive-assembly to be put, the melt after viscosifying afterwards
Spinning manifold is entered, after the dosing pump metering of the two-way melt respective component through being arranged in spinning manifold through secondary filter
Enter composite spining module and carry out spinning；
3) then through ring quenching, oil, the bucket that falls, drawing-off, shape and cut off after obtain side by side compound washing chopped fiber.
Further, Pillar recovery raw material includes that polyester bottle slice, the friction material of Waste Polyester textile processing, polyester waste silks are processed

Further, adhesive-assembly the putting of the quenched tune of liquid phase includes that interconnective vertical vacuum separating still and horizontal quenched tune glue still,
From top to bottom being provided with multi-layer porous plate in vertical vacuum knockout tower, the bottom that horizontal quenched tune glues still is provided with augering screw,
It is 280～300 DEG C that vertical vacuum knockout tower and horizontal quenched tune glue the temperature of still, and the vacuum of vertical vacuum knockout tower is
300pa～100Pa, it is 150Pa～50Pa that horizontal quenched tune glues the vacuum of still, quenched tune is adhesive-assembly put in the time of staying be
30min～120min；As preferably, the vacuum of vertical vacuum knockout tower is 250pa～185Pa, and horizontal quenched tune glues still
Vacuum is 100Pa～60Pa, quenched tune is adhesive-assembly put in the time of staying be 60min～90min.
Further, the mass ratio of the second road melt and first via melt is classified as 2:3～3:2.
Further, the wind speed of ring blowing is 1.0m/s～2.5m/s, and pathogenic wind-warm is 20～30 DEG C.
Further, upper profit rate is 18%～28%.
Further, spinning speed 400m/min～1250m/min.
Further, as-spun fibre draws god's multiple 3.2～4.5.
Further, drawing of fiber temperature: 72 DEG C～78 DEG C.
Further, the oil preparation used that oils is silicone finish, without silicon finishing agent or other functional type finishing agents.
Further, the setting temperature of fiber is at 125 DEG C～160 DEG C.
Further, the shaping time of fiber is at 25min～40min.
Compared with prior art, the present invention, under conditions of raw material is identical, glues technology by the employing quenched tune of liquid phase real
The viscosity differences of existing two-way target melt, achieves the life of parallel composite fiber under the precondition ensureing fiber spinnability
Produce.Described raw material can selected from for polyester bottle slice, Waste Polyester textile processing friction material, polyester waste silks processing friction material,
The mixture of the two or more in the friction material of mylar processing etc., greatly reduces the quality requirements to raw material, from
