Abstract
The invention provides a fiber drawing method. The fiber drawing method comprises the steps of preparing gel-spun fibers, bundling and pre-drawing, extracting, drying and hotly drawing, and is characterized in that an initiative fiber feeding procedure is increased before the step of bundling and pre-drawing. With the adoption of the fiber drawing method, the fineness deviation of the fibers can be reduced and the dispersion degree of the fineness of the finished-product fibers is also reduced; meanwhile, waste fibers generated in a drawing procedure are reduced and the cost is saved; the tension of the gel-spun fibers can be conveniently adjusted and keeps constant in a drawing process; meanwhile, the manpower is saved and the labor production efficiency is improved.
Description
Technical field
The present invention relates to the draft process improved in a kind of fiber production process, particularly relate to the drafting method in a kind of superhigh molecular weight polyethylene fibers production process, this drafting method can reduce fibre number deviation.
Background technology
In the production process of superhigh molecular weight polyethylene fibers, general employing gel spinning method.When gel fiber carries out drawing-off, generally first go up creel, and then carry out preliminary draft, extraction, drying successively, finally carry out hot gas spring to obtain fibre strength.In order to enhance productivity, the fiber of every batch of boundling reaches three, four rows, should control subtended angle, again constant-tension, and this just increases difficulty for the uniformity of guarantee gel fiber.
In existing production drafting process, boundling roller is all driven roll, gel fiber due to containing solvent naphtha, easier adhesion when going out fiber barrel, also easy roll banding.When the gel fiber of every batch of boundling is arranged more, the tension force of last row is always maximum, at the end of causing first row drawing-off like this, last row always residue, the gel fiber of 100 meters is reached time many, more than waste, and finished fiber fiber number is obviously less than normal compared with first row, increases the dispersion of finished fiber.
Chinese patent CN202107807U discloses a kind of spinning multistage drafting high-frequency inductance hot rollers, and primary structure is rotated thermometric transmitter formed by first pair of hot-rolling, second pair of hot-rolling, the 3rd pair of setting roller, thread guide, draw-off godet, up-coiler, high speed hot-rolling magneto, induction heater, electromagnetic valve, noncontact; Spinning enters first pair of hot-rolling by thread guide, second pair of hot-rolling is entered after first pair of hot-rolling is wound around certain number of turns, silk has certain drawing-off between first pair of hot-rolling and second pair of hot-rolling, after certain number of turns, the 3rd pair of setting roller is entered at second pair of hot-rolling, enter draw-off godet at the 3rd pair of setting roller through the silk of HEAT SETTING, enter winder winding winding forming by draw-off godet; Three pairs of hot-rollings are all the drafting systems of drive roll, and the heating of three pairs of hot-rollings all passes through solenoid control.The product produced by said apparatus has the advantages that fiber number is even, brute force is high, boiling water shrinkage is low.But the constant airspeed of three pairs of hot-rollings in this patent, although ensure that fiber number is even, the tension force of silk is unadjustable, and the position of three pairs of hot-rollings maintains static, and makes troubles to the adjustment of fiber number and tension force.
