Description

A kind of tow extraction equipment

Technical field

A kind of device for spinning is the utility model is related to, more particularly to a kind of tow extraction equipment.

Background technology

Current spining technology generally comprises dry spinning technology and wet spinning technology, and wherein wet spinning technology is One of main spinning process of chemical fibre, abbreviation wet spinning, the process that wet spinning includes are：First, spinning solution is prepared, then will Stoste extrudes to form thread from spinneret orifice, then stoste thread is frozen into as-spun fibre, and finally as-spun fibre is wrapped or directly enters Row post processing.

Fiber-forming polymer is dissolved in appropriate solvent, obtains definite composition, certain viscosity and there is good spinnability Solution, claim spinning solution.Also spinning solution can be directly obtained by homogeneous solution polymerization.High polymer first occurs molten before dissolving Swollen, i.e., solvent first penetrates into high polymer inside, the distance between macromolecular is constantly increased, and then dissolving forms uniform molten Liquid.Very long the time required to whole process, the speed of swelling process has a major impact to dissolution velocity.High polymeric solution spinning it Before, must through mix, filter and deaeration etc. spin before preparatory process so that the uniform properties of spinning solution are consistent, remove wherein folded The gel piece and impurity of band simultaneously remove the bubble in liquid.In viscose rayon production, prepare also to include maturation process before spinning, make to glue Glue has necessary spinnability.

Spinning solution delivers to spinning-drawing machine by circulating line, by measuring pump-metered, then enters through candle filter, connecting tube Enter spinning head.Spinning head is typically made of the alloy or tantalum alloy material of gold and platinum.Regularly it is distributed on spinning head Some eyelets, aperture are 0.05~0.08 millimeter.The stoste thread extruded from spinneret eyelet enters coagulating bath, in stoste thread Solvent to coagulating bath spread, coagulator to thread permeate so that stoste thread reaches critical concentration, separated out in coagulating bath And form fiber.Diffusion and solidification in wet spinning are physical and chemical processes, but some chemical fibres in wet-spinning procedure also simultaneously Generation chemical change.Such as viscose rayon, sodium cellulose xanthate are decomposed into tModified Cellulose Fibers.

Wet spinning speed (referring to the first draw-off godet speed for batching as-spun fibre) is due to by solvent and coagulator double diffusion Speed and the fluid resistance of coagulating bath etc. limit, therefore are low more than melt-spun speed.The linear velocity of first draw-off godet is former with spinning The ratio between extruded velocity of liquid is referred to as spinneret draft ratio.Wet spinning draw ratio be usually very little on the occasion of, it is therefore an objective to raising shaped The stability of journey.

Spinning solution is the elastico-viscous body for having viscosity and elasticity concurrently.Stoste from spinneret orifice extrude when, have dieswell effect（Bar Strangle this effect）, the diameter of extrusion thread is more than spinneret orifice diameter.In wet-spinning procedure, swell than being generally 1~2.Led first Under the tensile force effect of wire tray, extrusion thread is tapered after maximum gauge is crossed, and thinning process is continued until that stoste is thin Untill stream is fully cured.The change of thread diameter is not only the result of tensile deformation, but also and mass transfer process in wet spinning It is relevant.It is fibre forming area that one section from spinning head to solidification point, which is spun journey, is the key area that fibre structure is formed.Wet spinning is come into being Fiber containing big quantity of fluid due to being in solvent swelling state.Macromolecular has very big activity, and the degree of orientation is very low, its shape State structure is extremely close with spinning process condition relation.Selection and control spinning process condition, can be made varying cross-section shape Or special capillary structure and the fiber of property.

Wet spinning has a variety of forming modes, and spinning-drawing machine also has a variety of structures.Such as there are one-bath process or double baths Method, there are deep bath method or shallow bath method, there is shaping etc. in funnel shaping or pipe.The coiler device of wet method Spinning Machine for Long Filament has centrifugation pot type Or bobbin formula.Generally use spinning after-processing combination machine when spinning chopped fiber, the as-spun fibre after each spinning part shaping are collected Beam is synthesized, is carried out continuously post processing.

Due to containing spin solvent in the spinning solution of wet spinning, it is fixed therefore, in its as-spun fibre will necessarily also to contain The spin solvent of amount, but this part of solvent is unwanted, and also these solvents can also produce to the performance of fiber Detrimental effect, therefore, it is necessary to eliminate this spin solvent after as-spun fibre is formed, the in the industry also referred to as extraction of fiber Take, i.e. spin solvent is extracted from fibrous inside, disposed.Typically using the side of abstraction pool in spinning industry Fiber is immersed in service sink by formula, is drifted repeatedly, and is fallen the solvent washing on fiber by the flushing of circulating water, and is accompanied by Mechanical agitation.But this cleaning method will certainly cause to change to the property of fiber script, or even fiber can be caused need not The infringement wanted, influences fiber quality, more bright the drawbacks of this processing method especially in long filament existing for fiber bundle-like It is aobvious.Therefore, it is necessary to open a kind of new extracting process and extraction equipment that are directed to the long filament in fiber bundle-like, can obtain preferably Effect of extracting, it can avoid causing unnecessary harm to fiber during extraction again.
