Description
The present invention is that a kind of polypropylene fibre of textile industry is thin
The spinning method of coloured cut staple.
Polypropylene fibre is being commonly called as of polypropylene fibre, this fiber is in chemical fibre is produced, can only spin 6D above coarse staple fibre and long filament in the past, this crude fibre can only be used for knitting the thick shelves fabric of classes such as woven bag, bunting, carpet, so limited the kind development of polypropylene fiber product.Along with the develop rapidly of China's chemical fibre career, polypropylene fibre can spin the following fine fibre of 2D, and this increases the variation of commodity for the Application Areas that enlarges polypropylene fiber, and the raw cotton problem in short supply that solves textile industry has significance.
The warming dress of USN all adopts polypropylene fiber to manufacture abroad at present, and the sweater made from polypropylene fibre in the Olympic Games is called " super underwear ", and the every cover of short sweater and pants is up to 100 dollars.Its characteristics of clothes made from polypropylene fiber have comfortable and easy to wear, light, and good permeability is non-hygroscopic, and it is strong to lead the wet sweat of leading, and easily washes easily and do, and is very welcome so make functional clothes with polypropylene fiber.
Develop the development of polypropylene fiber in apparel industry, at first to solve the spinning problem of textile industry, the external existing at present producer of spinning polypropylene staple fibre spun yarn such as gondola HIMON company, its method is carried out on cotton spinning apparatus, but its method is inappropriate owing to many-sided reason of equipment and technology to China.
It is thin that purpose of the present invention is intended to solve polypropylene fibre
Coloured cut staple utilizes the existing homemade cotton equipment that spins of China, explore the process of a cover spinning, spin and be suitable for weaving industry, apparel industry, aspects such as industrial cloth use yarn, to save equipment investment, improve the fabric class of polypropylene fiber, satisfy people to the needs of polypropylene fiber to functionalization, the development of diversified commodity.
Big according to the polypropylene fiber bulkiness, the collectivity cohesive force is poor, rolling, one-tenth net, slivering, the resultant yarn difficulty, particularly add the vicissitudinous again characteristics of colored fibre performance behind the Masterbatch, solution of the present invention comprises the design of process portion condition and the part reform of device therefor, and its concrete scheme is as follows:
One, process portion
Process of the present invention is similar substantially to cotton spinning, but has increased the treatment process that gives to raw material before cotton cleaning process, so process process of the present invention is: give processing-blowing-comb and parallel cotton fibers prior to spinning-drafting-rove-spun yarn-winder-one-tenth bag.
The standard that requires to the polypropylene fiber raw fiber:
Fiber number: 1.2D-1.98D,
Length: 36.6mm-40mm,
Crimpness＞8/25mm,
Than resistance＜10 " Ω
Powerful relatively: 4.1-4.5g/D
Elongation: 40-60%
Oil content: 6.5-8.5%
Color and luster: shades of colour
1, gives the treatment process method: in order to guarantee yarn quality, raw material through sampling check carries out reasonable cotton by the difference of quality of fiber, color and luster, oil content size, crispation number, the lap waste cotton that adds will carry out the finish of adding of 0.5-1%, and necessary before use economy-combat bag pressure is tight, avoid the bulking intensity of lap waste cotton big, influence the lap uniformity.Because fiber is in the volatilization of transporting and depositing finish in the process, oil content does not reach necessary requirement, easily produces static, and the present invention has adopted the water treatment of giving to raw material, and the feedwater of spraying before raw material enters blowing makes moisture content in 3-5%.
2, blowing process method: the polypropylene fiber bulkiness is good, does not generally need strong shredding, checks two of the appropriate to the occasion employings of bulking intensity difference, utilizes home equipment A

201Four in carding machine.Adopt card wire formula hired roughneck, its speed is: porcupine hired roughneck's speed is 600-700 rev/min, and two of scutching cotton hired roughnecks check and are 800-900 rev/min, and one is 900-1000 rev/min when checking.Because polypropylene fibre dimension impurity is few, reduce cost in order to economize on cotton, so each dirt rod spaces and should reduce or seal, other divides, and combing spaces spaces by spinning cotton=formula of raw fiber length+coefficient and deciding.Polypropylene fibre proportion is little, but easily produces static with metal friction, is 1200 rev/mins so inhale cotton fan speed.Rolling is the pure key of spinning in Qinghua operation of polypropylene fibre, because the polypropylene fiber bulkiness is strong, resiliency is big, regain is zero, easily produces static, so rolling is comparatively difficult, and easily adhesion, so at the design cotton rolling quantity about 400g/m, press roller and add and be pressed in 1000kg/cm
2More than, folder rove bar 4-6 root was with anti during system was rolled up, and lap length is controlled at the 20-25m scope, and lap is made the back and is bandaged with the winding cloth that is lined with Polypropylence Sheet, in case loose and maintenance moisture content.
3, carding process method:
Can spin the yarn comb and parallel cotton fibers prior to spinning be crucial.Polypropylene fiber combing degree on carding machine is less demanding, but the rate of transform is required to increase more than three times than spinning continuous type, and the present invention controls the rate of transform between 30-40%.Require each difference of flatness of cylinder, doffer, cover plate, licker-in, stripping roller etc. to want＜0.05mm, fineness reaches no burr, and hand-held colorful clothes examination wiping is sticking does not hang, and acutance has picotement when hand is touched.Main speed to each one is adopted as, cylinder speed A
186360 rev/mins in type carding machine, (the old machine of producing in the past in 60 years is not less than 280 rev/mins), cylinder and licker-in Transmission Ratio Control are between 1.9-2.2, and cover plate speed is at the 100-120mm/ branch, doffer speed 22-25 rev/min.It is 0.23mm that winter portion's main gauge is given cotton roller one thorn roll spacing for (is the allowable error 0.005-0.01 of unit with mm), and inlet is 10mm at the bottom of the little leakage, and licker-in-cylinder is 0.127mm, it is 0.71,0.69,0.66 that 5 of cylinder-cover plates space, 0.66,0.69mm cylinder-doffer is 0.127mm, front knife plate is suitable for reading to be 0.69mm, end opening is 1.1mm, the preceding inlet of cover plate down 1.1mm, end opening is 0.59mm, leaks end inlet 2.2mm greatly, middle 1.1mm, outlet 0.59mm, the stripping roller-doffer is 0.48mm, the quantitative design of comb and parallel cotton fibers prior to spinning sliver is at 25g/m, overweight generation putty pipe phenomenon, web sinks, and easily produces the limit, causes difficulty to spinning.The forward pull drawing-off is 1.3 times, and big iron roll pressure is 30-32kg/cm
2, to prevent the loose increase cohesive force of the carded sliver.Be pressurised into 5kg/cm to cotton roller
2, prevent to feed cotton and skid.The mote knife height is 1mm, and angle is 90 °, spaces to be 0.43mm.Three suctions have been cancelled in comb and parallel cotton fibers prior to spinning, have cancelled filter dirt.
4, also thick (drafting, rove), spinning process method:
The drawing frame channel number is decided on the resultant yarn weight unevenness, in the resultant yarn weight unevenness coefficient of variation 2.5% when following, can adopt two roads (head is not also, not also), if greater than 2.5% appropriate to the occasion employing, three roads (head also, two also, not also), its drafting radical slubbing is 6, two roads or three roads are 8, from being used in the calculate draft multiple.Quantitative two road of drafting is 18-20g/5m, the stifled eye of overweight easy generation, and the road is not 13-15g/5m, is beneficial to spun yarn and adopts little drawing-off.Drafting, rove, spun yarn roller add pressure ratio and spin cotton increase by 20%, space and look raw fiber length formula (spinning cotton spaces=raw material length+coefficient) and suitably relax 2-3mm, on the roller of drafting, rove, fine sand, preferably be coated with raw lacquer, reduce twining flower, and can increase the service life.Regular roving feeding is picked up coefficient and is controlled between the 55-62 scope about 4g/10m.Calculating rove axial winding density (radical/10cm), warp-wise rolling density (radical/10cm), when spinning forming tooth and tension force tooth,, should increase 1.25-1.5 times than textile according to twist size and obvolvent degree to rove, spun yarn Diameter Calculation.Front roller speed adopts, 1250 rev/mins on drafting, 190 rev/mins of rove, spun yarn 180-200 rev/min, yarn roller speed should be than spinning cotton type speed low 30%, otherwise end breakage rate will increase, drafting multiple: drafting, rove is near spinning cotton jacket drafting multiple, and the spinning-drafting multiple is unsuitable excessive, excessive easy generation static, influence the resultant yarn bar evenness, No. 13 yarns (45) of general spun yarn are not more than 30 times, and No. 15.5 yarns (38) are not more than 26 times, and No. 18.5 yarns (32) are not more than 22 times, because the polypropylene fiber percentage elongation is big, resiliency is big, control the spinning-drafting process well, otherwise easily produces the rubber yarn, the back area draft pressurization of spacing should be picked up coefficient with rove and cooperated suitably, and cooperation employing rubber Xiao or smooth Xiao.It is the 70mm water column that spun yarn is inhaled cotton vacuum.
5, winding process method
Winding process is simpler, but very important, because the polypropylene fibre fusing point is low, can not friction process, otherwise can make the yarn adhesion, difficult unwinding all becomes waste product.The present invention adopts paralleling tube favourable to reducing friction, and it is overheated be difficult for to produce, if adopt the tower tube, must " change tapering into 6 ° by original 9 ° 15.Winder speed is difficult for too high, is controlled at below 1000 rev/mins.The pressurization of steel ball tension force, general 36.9-28.1 yarn (16-21 props up) adopts the 22mm steel ball, and 15.5-18.5 yarn (32-38 props up) adopts the 19mm steel ball.The employing of devil catcher can be eliminated big slub yarn, also can prevent spring yarn, and No. 36 (16) are spaced and adopted 0.7mm, and No. 28 (21) adopt 0.6mm, and 15.5-18.5 yarn (38-32 props up) adopts 0.4-0.45mm.
The control of humiture in the technical process:
