Abstract
The invention discloses a production method of a low-temperature easy-to-dye polyester fiber. The production method comprises the following steps: (1) entering raw material slices into a screw rod extruder with electrical heating function through a bunker, so that the slices are in a fusion state; and (2) quantitatively pressing the fused material into a spinning assembly through a metering pump and spraying the fused material out through a spinneret plate to form tows in a spinning box body, and the like, wherein the raw material slices are polyterephthalic acid. propylene diester, the spinneret plate is the spinneret plate formed by mixing and ranking trilobal spinneret orifices and cross-shaped spinneret orifices, the total number of the spinneret orifices is 36-72, the trilobal spinneret orifices and cross-shaped spinneret orifices are in concentric circle shapes or concentric diamond shapes or arranged alternatively. Multiple gaps and surface grooves are formed on the surface of the polyester fiber produced by the method disclosed by the invention, so that water and dye can easily enter gaps between the fibers; and simultaneously, tube bundle shaped grooves or capillaries are formed along the fiber shaft direction, which provide passages for transfer of dye, thus the fiber has good easy-to-dye property, and the purpose of dyeing at room temperature can be realized.
Description
Technical field
The present invention relates to a kind of production method of chemical fibre silk, especially a kind of production method of low temperature dyeable polyester fiber.
Background technology
Along with the reach of science, at present the synthetic fiber technology has also had significant progress, and synthetic fiber are used in the commercial production such as weaving, clothes with characteristics such as its good typing effect, high strength, good springiness, ABRASION RESISTANCE corrosion resistance are strong in large quantities.In the production process of synthetic fiber, ejection forms as-spun fibre the spinneret orifice of melt from spinnerets, is processed into the finished product synthetic fiber through later process again.Existing artificial synthetic polyester fibers is processed by the fibre single thread juxtaposed beaming together, and existing fibre single thread cross section mostly is circular, certainly, the various irregularly-shaped hole silks that formed by the spray of irregularly-shaped hole spinnerets is arranged also, like the trilobal silk, and delta wire, cross silk.But artificial synthetic fiber chromatophilia in the market can be relatively poor, and behind the fibre single thread juxtaposed beaming, fibre single thread is arranged closely; The intermolecular interstitial structure that lacks; Chromatophilia is poor, and hygroscopicity is poor, is difficult to satisfy needs of people; Because raw material, fibre structure, production technology etc. all have considerable influence to the chromatophilia of finished fiber; Therefore good polyester fiber has big difficulty to explore a kind of chromatophilia, need a large amount of theoretical research and production practices, so people expects the polyester fiber that a kind of chromatophilia is good always.
Summary of the invention
But the production method of the low temperature dyeable polyester fiber of the polyester fiber that a kind of production chromatophilia that the objective of the invention is to provide for the deficiency that solves above-mentioned technology is good.
In order to achieve the above object, the production method of the low temperature dyeable polyester fiber that the present invention designed may further comprise the steps:
(1) the raw material section gets into the screw extruder with electric heating function through feed bin, makes section be molten;
(2) above-mentioned molten material quantitatively is pressed into filament spinning component and by the spinnerets ejection, in spinning manifold, forms tow through measuring pump;
(3) tow is cooled off by lateral blowing through spinning manifold, further cools off through the path;
(4) cooled tow is oiled;
(5) through handing over network to make the more even and obvolvent Du Genggao of tow oil-containing;
(6) tow is through the drafting forming of hot-rolling;
(7) coiling and molding;
It is characterized in that: described raw material section is polytrimethylene terephthalate.
As preferably, said spinnerets adopts trilobal spinneret orifice and cross spinneret orifice to mix the spinnerets of arranging, and wherein, spinneret orifice adds up to 36 to 72, and trilobal spinneret orifice and cross spinneret orifice are concentric circles or concentric diamond shaped or alternately.
As preferably, screw extruder is respectively distinguished temperature between 320 ℃～335 ℃; The control parameter is during the lateral blowing cooling: 18 ℃ of temperature, humidity 79%, wind speed 0.8m/s; Adopt oil process on the secondary when oiling, the parameter that oils for the first time is: the rate 0.22% that oils, oil dense 12%; The parameter that oils for the second time is: the rate of oiling is 0.52%, and oil is dense to be 16%; During drafting forming, through two hot-rollings tow is carried out drafting forming, the first hot-rolling speed is 1100m/min, and temperature is 94 ℃; The second hot-rolling speed is 3830m/min, and temperature is 146 ℃.
The production method of the low temperature dyeable polyester fiber that the present invention obtains, the employing polytrimethylene terephthalate is a raw material, and adopts trilobal spinneret orifice and cross spinneret orifice to mix the spinnerets of arranging; Thereby make fiber surface that many gaps and Surface Groove arranged, make moisture and dyestuff get between fiber, simultaneously easily; Groove or capillary that many tubuloses are arranged along the fiber axis direction; For the migration of dyestuff provides passage, so fiber has good chromatophilia, can realize the purpose of dyeing under the normal temperature and pressure.Simultaneously, the polyester fiber that adopts this method to process also has the characteristics of good hygroscopicity.
