Abstract
The present invention adds fluorescent powder in 0.2-6% total amount into polyester slice. The prodn processes include: producing fluorescent powder in 5-30% and polyester slice into mother grain, mixing mother grain in 4-20% and other material, stoving, melting spinning, oiling winding, balance bundling, drawing opening and hot setting, cutting and packing. The terylene staple product is ultra-white and needs no bleaching in further processing.
Description
The present invention relates to a kind of polyester staple fiber and production method thereof, relate in particular to a kind of ultra-white terylene staple and production method thereof, belong to the textile of chemical fibre technical field.
At present polyester staple fiber is to be main raw material with the polyester dacron, through section removal of impurities, drying moisture absorption, melt spinning, the coiling that oils, balance, boundling, stretching, curl, loose HEAT SETTING, cut off after packaging and warehousing.The polyester staple fiber whiteness of being produced by this method is general.After weaving, the means by bleaching reach the requirement of extra white, so the processing technology complexity, cost height, dawn fugitive color with this general white polyester staple fiber in textile mills.
The object of the present invention is to provide add man-hour after a kind of no longer will be through bleaching processing, ultra-white terylene staple and production method thereof that can direct deep processing.
The present invention is achieved in that a kind of ultra-white terylene staple, and it is to be main raw material with the polyester dacron, is equipped with phosphor powder again and makes brightening agent, and the addition of phosphor powder accounts for 0.03-0.07% of raw material total amount.
The addition of above-mentioned phosphor powder can also be to account for 0.036-0.045% of raw material total amount.
The production method of ultra-white terylene staple of the present invention is: its production craft step comprises polyester dacron section removal of impurities, the moisture absorption of vacuum drier drying, melt spinning, the coiling that oils, balance, boundling, stretching, curls, loose HEAT SETTING, cut-out, the brightening agent phosphor powder need dissolve earlier with the section of part polyester dacron and make phosphor powder polyester dacron master batch, adds together with all the other polyester dacrons sections and carries out the drying moisture absorption in the vacuum drier.
The addition of phosphor powder accounts for the 1-1.6% of master batch total amount in the above-mentioned phosphor powder polyester dacron master batch.
Production method of the present invention can be achieved in that a kind of production method of ultra-white terylene staple, its production craft step comprises polyester dacron section removal of impurities, the moisture absorption of vacuum drier drying, melt spinning, the coiling that oils, balance, boundling, stretching, curls, loose HEAT SETTING, cut-out, the brightening agent phosphor powder directly is added in the vacuum drier, concrete addition is: stop earlier vacuumizing before drying moisture absorption discharging, add the brightening agent phosphor powder, rerun a period of time, treat to mix basically the even back discharging spinning that is mixed.
Compare with present general white polyester staple fiber and production method thereof, the present invention makes brightening agent owing to added phosphor powder in the polyester dacron raw material, carry out two component blend spinning, make product have the extra white performance, its whiteness 〉=85, and the color aquatic foods are clean, clear and bright white, sunshine the colour-fast and white characteristics of keeping a public place clean forever.Add man-hour particularly, no longer will get final product direct deep processing, reduced production link, reduced production cost, improved labor productivity through bleaching processing.Simultaneously, also reduced pollution factor, shortened user's the finished product production cycle environment.Can be widely used in fields such as clothes, shoes and hats, sewing thread and decoration.
Below be detailed production process of the present invention:
One, granulation takes by weighing phosphor powder 10Kg, high-quality polyester dacron 990Kg, mixes after phosphor powder polyester dacron master batch is made in fusion.
Two, the polyester slice removal of impurities is cut into slices polyester raw material standby after the removal of impurities.
Three, the drying moisture absorption adds the polyester dacron raw material 950Kg of section after the removal of impurities in the rotary-drum vacuum drying machine, adds the phosphor powder polyester dacron master batch 50Kg for preparing again, carries out the drying moisture absorption.80-135 ℃ of rotary drum internal temperatures, internal vacuum-0.09～0.096mpa is moved 8-12 hours, and the moisture content of polyester slice is blotted and the slice surface crystallization, and moisture is controlled at below 0.02～0.03%, and the uniform temperature when melt spinning is provided.
Four, the raw material of melt spinning after with the drying moisture absorption adds and carries out two component blend spinning in the staple fiber spinning unit.Wherein extruder is respectively distinguished temperature: 1 district 270 ℃ ± 2 ... 7 districts 278 ℃ ± 1; Measuring pump is 9CC; The spinnerets hole count is φ 0.3m/m * 500 holes; Extruder pressure 5-7mpa; Spun filament is cooled off wind speed 0.4～0.5m/ second, 28-32 ℃ of wind-warm syndrome.Fuse after making PET section and phosphor powder by certain temperature, advance the formation certain pressure to extrude spinneret orifice shaping cooling, reach the effect of as-spun fibre by measuring pump to extruder.
Five, the spun filament that will the be shaped coiling that oils on staple fibre volume machine of reeling that oils, the moisture percentage that oils is 15-18%, winding speed 550-700m/ branch.The tow at each position is concentrated in together, by oiling, drawing-off, entering by feeding-wheel and to be subjected to silk bucket, in order to post processing processing.
Six, balance will be deposited more than 8 hours by the nascent tow in the silk bucket, to eliminate the interior gravitation of spun filament because of high-speed winding.Storage condition: 28 ± 2 ℃ of temperature, relative humidity 65% ± 5%.
Seven, boundling with suitable tension, is formed flat silk ribbon with some barrels of as-spun fibre marshallings.
Eight, stretching stretches silk ribbon on the stretching unit.Condition: 4.5-4.8 times of stretching general times, 70-72 ℃ of oil bath oil content divide that secondary is stretched oneself and yawn, one-level is 88-92%, secondary is 12-8%, by stretching, as-spun fibre is further elongated attenuate, improve powerful, reduction percentage elongation, and make fiber number reach requirement.
Nine, curling with the fiber after the straight stretching, through crimping machine, make fiber produce waveform by mechanical pressure, in order to frictional force that improves finished fiber and enhancing cohesive force, be convenient to cotton mill and use.
Ten, loose heat setting, the fiber with the dewing that stretches, curls, oils adds loose heat setting machine, by adding heat utilization hot air circulation, hydrofuge, typing, make the finished product regain reach public provisioning request 0.4%, HEAT SETTING is respectively distinguished 110 ℃ ± 5 ℃ in temperature one district, shaping time 25-27 minutes.
11, cut-out is sent the fiber after the loose HEAT SETTING into the wheeled cutting machine cut-out of ditch.Control principal length ± 8%, control overcut fibre rate ± 2%.According to the cotton mill requirement, can adopt conversion to collude the cog number, cutter number etc., the principal length of change finished fiber, and with Tension Control overcut fibre degree suitable, even weighing apparatus.
12, the fiber packaging and warehousing after will cutting off.
The present invention can also directly be added in the brightening agent phosphor powder in the rotary-drum vacuum drying machine without granulating.As the polyester dacron raw material 999Kg after the adding section removal of impurities in the rotary-drum vacuum drying machine of elder generation, after vacuumizing through heating in 8 hours, before discharging, stopped to vacuumize in 0.5-1 hour and add whitening powder 360～4509, rerunned 0.5-1.5 hours, treat to mix basically the even back discharging spinning that is mixed, other technology is the same.
