Abstract
The utility model relates to a production line of colored triangular acrylic fiber, in particular to a production line of colored triangular acrylic fiber with multiple color systems and small color difference, i.e. a production line for producing colored triangular acrylic fiber by using solution polymerization and sodium sulfocyanate wet spinning. The production line uses a strip-shaped arched dyeing solution injector head which comprises an injector head base, an injector head cap and a dyeing solution inlet pipe; the cross section of the strip-shaped arched dyeing solution injector head is in a hollow T shape; the injector head cap is a strip-shaped semi-cylindrical surface; and a plurality of through spray holes are arranged on the injector head cap alternately. The utility model provides a production line of colored triangular acrylic fiber with multiple color systems, fresh color and uniform dyeing, which can be directly used for post-spinning without post-spinning dyeing, thereby overcoming the dyeing quality defects of difficult deep color dying, the occurrence of colored spots and stripes and fiber whitening, simplifying the processing process, reducing the cost and shortening the processing cycle.
Description
Technical field
The utility model relates to a kind of production line that the color triangle acrylic fibers are arranged, particularly relate to the production line that the color triangle acrylic fiber is arranged that a kind of polychrome is, aberration is little, just a kind of polymerisation in solution and sodium sulfocyanate wet spinning of adopting produced the production line that route production has the color triangle acrylic fiber.
Background technology
Adopt the profile spinneret of non-circular pass,, can produce the triangle acrylic fiber of white through spinning technique optimization and improvement, again by after spin and adopt bulk fibre high temperature decatize mode to dye.Have multiple colouring problem thus: the glass transition temperature of acrylic fibers under humid tropical condition is 70～80 ℃, and the intensification when therefore dyeing must strictly be controlled, and needs to add accelerant or retarding agents according to dying shade.And the production technology difference of fiber (dry-spinning, wet spinning, comonomer form), dyestuff kind (performance) difference need be selected different dyeings for use.It is improper to control slightly, and very easily specking appears in the look flower.The aberration desired value (DEcmc) that characterizes colored fibre level-dyeing property and repeatability is usually greater than 1.5.In addition, after spin dyeing and need carry out in batches, unavoidable between each batch product in the difference of aspects such as color and luster, feel or outward appearance.Energy consumption height and coloured sewage quantity are big simultaneously, have also prolonged the process-cycle of product.All factors have all caused the fibre loss rate to improve, and have increased cost of processing.
At present, the method for conventional color acrylic fibre fiber production has endless tow continuous dyeing method, original liquid coloring method, gel staining method.Wherein endless tow continuous dyeing method is consistent with back spinning short fiber dyeing mechanism, and the finished product tow is carried out high temperature pad dyeing, aberration between only having solved batch, and other problems still exists, and only is fit to small lot batch manufacture.The original liquid coloring method is before spinning spinning solution to be mixed with pigment, makes coloured spinning solution, directly carries out spinning production.The original liquid coloring method of CN117004C, CN1523161, CN1465758A explanation exists pigment to grind, and the granules of pigments particle diameter is bigger in coloured stoste, and the spinning difficulty increases, and chromatogram is few.Gel staining method is with liquid dyes the as-spun fibre that is under the gel state to be dyeed in the acrylic fibre wet spinning process.The dyestuff allotment is flexible, so colour system is many, chromatogram is wide.4 kinds of representative in the world acrylic Fibre Gel Dyeing process routes have been introduced in " Kingsoft oiling fibre " the 4th phase of calendar year 2001 " application of gel-colored technology in acrylic fibers NaSCN two-step process ", domestic also have acrylic fibers company to introduce wherein Solutia, Sterling technology to produce conventional color acrylic fibre, as " Kingsoft oiling fibre " the 1st phase in 2004 " gel-colored technical optimization ".But it is solvent that Solutia company, Courtaulds company and Snia company adopt DMAC, NaSCN and DMF respectively, all is in stretching or the stretching poststaining, and dyeing time is short, and difficulty is dyed dark color.And after stretched, the amorphous region degree of orientation of fiber improves, and internal capillary is elongated and attenuates simultaneously, influences the infiltration of dyestuff, level-dyeing property variation, Yi Sehua.Especially DMAC and DMF are organic solvent, the spinning solution concentration of this process route adopts the NaSCN method of inorganic solvent to double above, so fibre structure is finer and close during spinning technique, the fibrous inside voidage is little, the cavity is little, dyestuff penetration is slow during dyeing, and dyeing and ventilative time will be grown, and level-dyeing property is poor than the NaSCN method.Sterling company is solvent with NaSCN, and to spray dyeing before the conventional acrylic fibers employing stretching of circular cross-section, shower is in the relative arranged vertical in tow two sides.Shortcoming is that dyeing time is grown (＞30 seconds), and for dye liquor is penetrated in the tow as much as possible, spray pressure is big, has the gel monofilament phenomenon that is thrust.Especially wet spinning triangle acrylic fibers adopt and accelerate the solidification forming mode, and fiber weakness is big relatively, easier thrusting.Road hot-stretch after the gelatine silk that is thrust can't be finished, coloured light is different from the fiber that stretched, and is prone to aberration, and the powder height.In addition, for guaranteeing higher spray pressure, the shower top nozzle distributes less, and spacing is bigger, and owing to constantly circulate through the dye liquor of tow, nozzle is easily stifled, in case relatively the nozzle of arranging can't avoid that plug-hole causes on dye the dead angle.So it is higher dyeing striped probability to occur, even whiting is arranged.The DEcmc fluctuation is bigger, sometimes greater than 1.0, even 1.2.
In sum, wet spinning triangle acrylic fibers are because its each side physical and mechanical properties and dyeability are different from conventional acrylic fibers, so need more the improvement to satisfy its performance requirement on the preparation method, to disclose a kind of be the production line that the wet method of solvent is spun the color triangle acrylic fibers with NaSCN and also still there is not document now.
Summary of the invention
Technical problem to be solved in the utility model is at the above-mentioned state of the art, and a kind of production line that the color triangle acrylic fibers are arranged that spins the polychrome system spun after dyeing can be directly used in, bright-colored and even dyeing after not needing is provided.This production line relates to a kind of special dye liquor injector head, in polymerisation in solution and the production of sodium sulfocyanate wet spinning technology route the color triangle acrylic fiber is arranged, avoided difficult dyeing quality defective of dying dark color, look flower, striped even fiber whiting, and simplified processing process, reduce cost, shorten the process-cycle.
