Specific implementation mode
With reference to the preferred embodiments of the present invention will be described in detail, so that advantages and features of the invention can be more easy to
In being readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
In one embodiment, a kind of production technology of terylene water soluble fiber, the production technology of the terylene water soluble fiber
Step includes：By raw material, consolute, melt enter distribution duct, pipe insulation a to constant temperature under screw rod head pressure at high temperature
Degree is uniformly fed into each spinning station by principle of equidistance, and each spinning station carries high-accuracy melt metering pump, and melt is through metering pump
After accurate measurement, it is uniformly sent to each filament spinning component, silk is emitted into from spinneret after metal sand and strainer filtering, from spray
For the molten state strand that filament plate comes out by with the side-blown air cooling of laminar flow in the cross air blowing device of optimization, strand after cooling is vertical
It enters back between winding, through the commutation of sub-wire roller, sub-wire, then in the draw roll of heating after drawing-off network, is rolled up into high speed
Doffing is rolled up automatically around head.
It further illustrating, the raw material includes polyacrylonitrile fibre, and the high temperature is 320 DEG C, and the pressure is 0.2MPa,
The temperature of the cooling is 45 DEG C, and the temperature of the draw roll of the heating is 80-100 DEG C.
In further explanation, the spinning, stretching of polyester filament and deformation processing carry out in each spindle position.Later process
When being processed to the silk ingot in preceding road, although can improve or make up some disadvantages by adjusting the technique of later process,
Some disadvantages not can overcome the disadvantages that not only, it is also possible to be amplified, such as the difference between spindle position.Therefore, it is to protect to reduce the difference between spindle position
Demonstrate,prove the key of quality of polyester filament.With the development of spining technology, polyester filament production has following productive prospecting.1, speed of production
It is high：With the development of long filament production technology, spinning speed is more and more high, and the present overwhelming majority has reached 3500m/min or so.It spins
The raising of silk speed, to technique, equipment, operation etc., more stringent requirements are proposed.2, package capacity is big：The net weight of undrawn yarn bobbin
It is increased to 15kg from 3~4kg, textured filament bobbin is increased to 5kg by 1~2kg.After package capacity increases, to winding mechanism, bobbin
The uniformity of yarn quality, vanning transport of bobbin etc. propose new requirement.3, feed quality requirements are high：The matter of polyester raw material
Amount is very close with the spinnability of long filament and the relationship of product quality.Except the quality index for requiring slice --- it is intrinsic viscosity, soft
It is qualified outer to change point, diethylene glycol content, carboxyl-content, ash content and aggregated particle, meanwhile, the face shaping of slice has Non-carbon black grain
Son, the influence of the distribution of relative molecular mass, moisture content to spinnability are also very big, especially influence of the moisture content to high speed spinning
Bigger, it is desirable that the ancient water rate of slice is no more than 30~50ppm.It is required that the quality of raw material reaches quality index, uniformity, and
It is required that stable quality between batches, consistent.4, technology controlling and process is stringent：Long filament production requirement technological parameter is very stringent.Example
Such as, melt temperature fluctuates up and down is no more than ± 1 DEG C, and cross air blasting wind speed difference is not more than 0.1m/s, and spinneret requires shovel board everyday
Face.Also there is higher requirement to public work (such as water, gas, vapour, electricity).5, it requires to carry out total quality control：Long filament produces
A kind of pipelining of more spindle positions, multiple computer desk, frequent operation, labour intensive, the relationship of management work quality and quality of polyester filament
Very closely.In order to ensure product quality, it is necessary to carry out total quality control, establish quality certification system.6, it requires to carry out inspection
It tests, pack, storage and transportation work：In order to ensure quality of polyester filament, every batch of raw material is both needed to examine its physical index, it will be by winding bobbin
A its visible defect of inspection, will be sampled finished silk dyeability or one-hundred-percent inspection, and different size cannot in packaging process
Mixed bag.Invite storage and transport in addition, to note, storage can not weather exposure, heap case cannot be excessively high, handling require put down gently, transport
It is defeated to avoid jolting as possible.Polymerization technique is divided into using water as the suspension polymerisation of medium and using solvent as two class of polymerisation in solution of medium.
Condensate is precipitated with flocculent deposit obtained by suspension polymerisation, need to be re-dissolved in solvent and spinning solution is made.It is molten used in polymerisation in solution
Agent can dissolve monomer, and can dissolve condensate, and gained polymer fluid is directly used in spinning.Polymerisation in solution solvent for use has dimethyl
Formamide, dimethyl sulfoxide (DMSO), sodium sulfocyanate and zinc chloride etc..Use the polymerization time of first two organic solvent generally 10h with
On, but dissolving power is strong, and the concentration of spinning solution is higher, can properly increase spinning speed, and solvent recovery is also easier, gained fiber
Better performances, and the material of equipment is required relatively low；And with latter two inorganic solvent, polymerization time only needs 2h, gained fiber white
Degree is preferable.Spinning solution is generally polyacrylonitrile condensate, and number-average molecular weight is 53000~106000, and fibre whiteness is preferable, heat
200~250 DEG C of decomposition temperature, molten point is up to 320 DEG C.Therefore, the wet spinning and dry method of polyacrylonitrile fibre high polymeric solution
Spinning is made.The concentration of dope of dry spinning is 25%~30%, and spinning speed is fast, but because the thread that spinning head sprays cures
Slowly, it is easily bonded before solidification, the spinning head that hole count cannot be used more, spin solvent only dimethylformamide is a kind of, gained fiber
Structure even compact, suitable for weaving silk-like fabric.Wet spinning is suitable for making staple fiber, and fiber fluffy is soft, preferably weaves imitative
Wool fabric, spin solvent used is in addition to the solvent of polymerisation in solution, also dimethylacetylamide, ethylene carbonate, nitric acid etc.,
The boiling point of most of solvent is higher, is not easy to steam in spinning process.It has studied with melt spinning legal system polyacrylonitrile the eighties
Fiber without preparing condensate stoste, saves recycling and the circulatory system of solvent with water for polymeric plasticizer, fiber
Physical property and fiber made from dry or wet spinning are essentially identical, have entered the intermediate experiment stage.It is external that there are many nitriles
Synthetic fibre production process route, is divided by solvent, mainly there is sodium sulfocyanate (NaSCN), dimethylformamide (DMF), dimethyl
Acetamide (DMAC), dimethyl sulfoxide (DMSO) (DMSO), acetone, ethylene carbonate (EC), nitric acid (HNO3) and zinc chloride (ZnCl2)
Deng.The present invention provides a kind of production technology of terylene water soluble fiber, has the advantages that cost-effective, environmental protection, energy saving.
The specific implementation mode of the present invention, but scope of protection of the present invention is not limited thereto, any to be familiar with this field
Within the technical scope disclosed by the invention, changes or substitutions that can be made without creative work should all be contained technical staff
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be to protect model defined by claims
Subject to enclosing.
