Description
Technical field
The present invention relates to a kind of processing method of on fused mass directly spinning, producing composite fibre; Especially can be with two kinds of different fibrous raw material spinning; Be incorporated into the power networks compound, step of reeling accomplishes, and 20 fixed length processing method of the different contraction composite fibre of heavy spinning cake is surely produced in spinning, every potential energy of reeling simultaneously.
Background technology
Owing to the production technology reason; Domestic manufacturer generally adopts two-step method to produce different contraction composite fibre; Its spinning of this production method, every potential head number of reeling are 6,12 mostly, are exactly at most 20, are common conventional spinning, coiling technology; Independent spinning through pre-oriented yarn (POY) and full-drawn yarn (FDY), reel after the unwinding different contraction composite fibre of processing that is incorporated into the power networks again, two-step method production exists following unfavorable factor:
1. production efficiency is low: the two-step method recombination velocity is about 800m/min;
2. production cost is high: two-step method is to be composited through later process behind two kinds of independent spinning of fiber, the coiling again, and production procedure increases, and the equipment input increases; Floor space is big, and labour cost is high, and raw materials consumption is big; The production cycle field, circulating fund takies increase, and the high-class product rate is low;
3. quality is unstable: the two-step method production procedure is long, and the control point is many, and influence factor is many, and is wayward;
Produce the unfavorable factor that different contraction composite fibre brings in order to solve two-step method, people have invented one-step method and have produced different contraction composite fibre.Patent documentation CN101824690A discloses a kind of " spinning, the winding combined manufacturing process of 24/position multi-heterogeneous hybrid yarn composite fiber of one-step method "; Processing step be successively get the raw materials ready, crystallizing and drying, fusion and filter, melt distributes, spin pre-oriented yarn and fullly drawn yarn (FDY) simultaneously, oil, stretch entirely preparatory network, fullly drawn yarn (FDY) drawing-off and typing, composite network and coiling (fixed length is heavy surely); Spinning and coiling is disposable synthetic, and every potential energy is produced the heavy surely spinning cake of 24 fixed length simultaneously.Yet, the different contraction composite fibre that adopts above-mentioned section spinning technique one-step method to produce, the different contraction composite fibre with respect to fused mass directly spinning technology one-step method is produced needs pelletizing, packing, dry supervisor, increases production cost, the quality control difficulty.
Summary of the invention
In order to overcome above-mentioned defective; The invention provides a kind of fused mass directly spinning and produce the processing method of different contraction composite fibre, this method adopts the fused mass directly spinning technology, makes full use of existing spinning, winding apparatus and transformation; Spinning and coiling is disposable synthetic; Every potential energy is produced the heavy surely spinning cake of 20 fixed length simultaneously, has improved productivity effect and economic benefit, produces high-quality different contraction composite fibre.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of fused mass directly spinning is produced the processing method of different contraction composite fibre, is undertaken by following processing step:
1. esterification: carry out esterification by raw material p-phthalic acid and ethylene glycol;
2. prepare polyester fondant: after the raw material esterification, gather the preparation polyester fondant through precondensation and final minification again, the viscosity of prepared polyester fondant is 0.650;
3. melt Conveying: melt gets into pre-oriented yarn spinning manifold and full-drawn yarn spinning manifold respectively through two-way melt distributing pipe;
4. spin pre-oriented yarn (POY) and full-drawn yarn (FDY) simultaneously: the melt that gets into the pre-oriented yarn spinning manifold forms pre-oriented yarn through the metering of pre-oriented yarn measuring pump, assembly spray silk and ring cold wind blower cooling back successively; Each pre-oriented yarn spinnerets in the described pre-oriented yarn filament spinning component is divided into four districts, and the spinneret orifice on the pre-oriented yarn spinnerets is a circular arrangement; The melt that gets into the full-drawn yarn spinning manifold forms full-drawn yarn through the metering of full-drawn yarn measuring pump, assembly spray silk and ring cold wind blower cooling back successively; Each full-drawn yarn spinnerets in the described full-drawn yarn filament spinning component is divided into four districts, and the spinneret orifice on the full-drawn yarn spinnerets is a circular arrangement;
5. oil: pre-oriented yarn oil system on pre-oriented yarn oils, and the pre-oriented yarn after oiling gets into first, second draw-off godet successively, and oil system is every 20 the tunnel on the said pre-oriented yarn; Full-drawn yarn oil system on full-drawn yarn oils, and oil system is every 20 the tunnel on the said full-drawn yarn;
6. the preparatory network of full-drawn yarn: the full-drawn yarn after oiling gets into and carries out preparatory network in the preparatory Network device;
7. full-drawn yarn drafting forming: silk forms full-drawn yarn through first hot-rolling, the heating drawing-off of second hot-rolling and typing successively behind the network in advance;
8. network combined: the full-drawn yarn after the pre-oriented yarn after oiling and the typing respectively by the second spinning reel and second hot-rolling draw carry out to the composite network device network combined; Process different contraction composite fibre; Said first and second draw-off godet is every 20 silk roads, and said composite network device is every 20 the tunnel;
9. reel: abnormal contraction composite filament gets into and is wound into the heavy surely spinning cake of fixed length in the up-coiler, and the reciprocal groove drum of said up-coiler is every 20 silk roads, and paper tube is 20 every.
The advantage of production and processing method of the present invention is:
1. production efficiency is high: speed of production can reach more than the 3500m/min;
2. productive rate increases: every potential energy is produced 20 spinning cakes simultaneously;
3. production cost has reduced about 40%: production procedure is shortened, and to the scrap build less investment, labour cost does not increase basically.
4. constant product quality improves: output increases, and the melt-flow momentum increases, and melt time of staying in pipeline shortens, and has reduced the melt degraded;
