Abstract
The invention discloses a continuous spinning process for a viscose coarse denier flat filament, which comprises the following steps that: viscose measurement and forming, washing, drying and tube forming; the measured viscose reacts and is formed into filament strips in a glass forming tube; the filament strips formed in the glass forming tube are tractioned to a sink by a pressure roller of the multi-stage sink to be washed in a plurality of stages; the filament strips on the tail end of the multi-stage sink are tractioned to a steam dryer by the pressure roller; and the steam dryer dries the filament strips, and then forms the dried filament strips into a tube. The invention completes a plurality of procedures on a production line, optimizes the process, and achieves the purposes of shorter process, reduced process fluctuation, small quality difference between batches, reduced end breakage, higher yield, lower cost, higher quality and lower labor intensity.
Description
Technical field:
The invention belongs to the viscose filament yarn production technology, be specifically related to be applicable to the continuous spinning process of viscose glue heavy denier yarn flat filament product.
Background technology:
Existing heavy denier yarn flat filament production technology adds coiling by semi-continuous spinning machine, and washing system one cover, one of drying kiln and skeining, one-tenth cylinder device constitute.Production process: viscose glue after metering through dark bathe spin with acid reaction after, further fully react solidifying on roller, the acid removing roller, thereafter by hank reeling machine circle bunchy with acid.Again through washings such as washing system water, alkali, acid.Dry through drying system; At last in becoming cartridge system to form final products.
The problem that above-mentioned production technology exists is: is made up of a plurality of equipment owing to produce each operation, that is to say that each operation carries out on different equipment, and the entering next process must shifts product; Cause technological process long; Technological fluctuation is big, has mass discrepancy between batch, is prone to broken end, yield is low, cost is high; Quality is low, and labour intensity is big.In process of production because span is big between system equipment, the factor that technology exists many influences to produce, like: a, because what adopt is former spinning machine transmission mechanism, the restriction rotating speed spin speed and improve.B, when skeining, be not complementary with the rotating speed of spinning machine, cause the hank reeling machine fluctuation of service; C, strand carrying out washing treatment are to use the driving lifting, and causing lifting must be to soak after forming in batches, exists uniformity poor; D, strand washing in the washing system intermediate gap, the time is long; E, strand reaction not exclusively remain the esterification degree height; F, in drying system with bundled shape, inner strand can not effectively be dried.Restriction heavy denier yarn flat filament output increases and product quality improves.
Summary of the invention:
The present invention provides a kind of continuous spinning process that is used for viscose coarse denier flat filament; The present invention accomplishes a plurality of operations on a production line; And technology is optimized, reach shortened process, reduce technological fluctuation; Mass discrepancy is little between batch, reduces broken end, improves yield, reduces cost, improves the purpose that quality is low, reduce labour intensity.
For realizing above-mentioned purpose, technical scheme of the present invention is following:
The continuous spinning process that is used for viscose glue heavy denier yarn flat filament; Comprise viscose glue measure and shape, washing, oven dry and become tube; It is characterized in that: the viscose glue after the metering reacts the moulding strand in the glass ware forming pipe, and the strand of glass ware forming Guan Guanzhong moulding is drawn to sink by the hold-down roller of multistage sink and carries out multistage washing, and the terminal strand of multistage sink is drawn to steam drying machine by hold-down roller; Steam drying machine is dried strand, and the strand after will drying again becomes tube.
Said multistage sink is successive by multistage hold-down roller, and the base plate of sink bottom is set to the inclined-plane, and strand reduces the raffinate in the moulding in the pipe through first group of hold-down roller; Nature gets into first order sink; And after piling up washing by soaking in order, reducing the raffinate in the first order washing through second group of hold-down roller, nature gets into second level sink; Repeat said process, strand gets into terminal multistage sink.
Strand in the multistage sink of said end is drawn to holding on the conveyer belt of steam drying machine top through the hold-down roller of end; Through the hold-down roller between multistage sink and the steam drying machine and hold the traverse bar mechanism swing strand that is provided with between the conveyer belt; Strand is holding on the conveyer belt oven dry rear haulage to becoming to become tube on the cylinder device, is arranged in to hold an air draft case of conveyer belt top the steam that the strand oven dry forms is discharged.
The speed of spinning of said strand is 60-130m/min.
Said speed of holding a conveyer belt is lower than spins speed.
Acid bath composition and concentration thereof in the said pipe in the moulding are sulfuric acid 130 ± 20g/l, sodium sulphate 260 ± 33g/l, zinc sulfate 19 ± 2.5g/l, 50 ± 8 ℃ of acid bath temperature, proportion 1.272 ± 0.15.
Beneficial effect of the present invention shows:
One, adopt moulding in the pipe, continuity washing, continuity oven dry, nothing broken end continuity to become tube; Guarantee shortened process; Reduce technological fluctuation, mass discrepancy is little between batch, reduce broken end, improve yield, reduce cost, improve quality low, reduce labour intensity.
Two, adopt the hold-down roller transmission mechanism, operation raffinate before effectively reducing is carried high-speed spinning, when skeining, can mate with the rotating speed of viscose glue measure and shape equipment.
Three, because strand moulding and multistage washing coupling together, no longer need be used the driving lifting during strand carrying out washing treatment, guaranteed the uniformity that strand soaks.
Four, be connected with strand moulding and oven dry before and after the multistage washing, shorten wash time.
Five, the sink inner bottom part is set to swash plate, and the strand of some can be deposited in the sink in order, has guaranteed soak time, washing quality, and does not receive the influence of draft speed fine difference in addition.
Six, drying plant adopts conveyer belt type oven dry transmission means, and strand in the raw, does not influence strand tension force when oven dry, further guarantees uniformity, the nothing broken end of strand quality.
Seven, conveyer belt type oven dry transmission means has also overcome the drawback that traditional bundled strand can not effectively be dried.
Eight, owing to set up transversing mechanism, strand is arranged in spiral when getting into drying plant and holds on the conveyer belt, can guarantee drying time, can promote speed of production again.
