(3) pneumatic apparatus for collecting, behind the yarn of front roller output, add the pair of control device, wherein, be roller above, below by forming by the special pipe and the grid ring of air draught aggtegation, yarn is closely aligned, has significantly reduced the width of yarn band in the traditional ring spinning twist triangle zone, help fiber in the yarn twisted with the fingers reliably and be rolled onto in the sliver.And make separating of drawing-off and set, no set effect in the draw zone, no drawing-off effect in the set district, thereby avoided having influenced owing to the existence of set effect in the draw zone distribution of friction field, and the yarn after the drawing-off is again after set, reduce the yarn width, increased tightness, helped improving yarn quality.
The more excellent scheme of this equipment is:
It is that the nylon monofilament of 0.08mm is made that described grid ring has diameter, and the voidage of grid ring is 24 ~ 27%, and the order number is 3600/cm
2
The vacuum of gathering in the described special pipe is 2000pa, and it gathers tension force is 1.05.
The spinning process of this equipment is: decorative yarn intermittently feeds from rear roller, the base yarn feeds continuously from middle roller, traction through the front roller and two rollers in proparea, synthetic yarn is to having bothrium and the inner special pipe that is in negative pressure state, be subjected to suction function to be adsorbed on the position of the corresponding notch in grid ring surface, the yarn that is gathered control travels forward with grid ring, by the output of output jaw.
Encoder on the described front roller tests the speed to front roller, and tach signal sensed the speed change intelligent controller, the speed change intelligent controller is according to the technological parameter requirement of setting, and the servomotor speed change of control rear roller realizes the feeding at intermittence of decorative yarn on the rear roller.
Special through improved device structure, make spinning have unique advantage, mainly show as:
(1) the bar solid carbon dioxide is put down: because many rove are simultaneously drafted, play certain also cooperation usefulness, many corings bar remedies mutually, improves bar and does, and reduces details, slubbing;
(2) filoplume is few: owing to there is the yarn after the drawing-off of many velamens to twist together, substantially eliminated front roller to the spinning twist triangle zone between the twisting point, and factors such as the contraction of air-flow and polymerization, the termination of fiber is all twisted with the fingers in the yarn, yarn formation structure is the tightst, yarn appearance is bright and clean, filoplume is few, and yarn twisting helical structure is high-visible, and fiber does not almost have inside and outside transfer.Filoplume can reduce by 15 ~ 20%, and is wherein almost nil greater than the plumage that becomes mildewed of 3mm;
(3) powerful high: because of yarn has the characteristics of strand, fiber alignment is regular, so powerful the raising, the fracture strength of yarn can improve 8 ~ 15%.ABRASION RESISTANCE might as well;
(4) cloth cover is effective: clear with the fabric face that the spun yarn of the method is made into, stiffness is good, and the cloth cover filoplume is few, has the style of strand fabric.Simultaneously because basic yarn can have multiple choices with decorative yarn, thereby can form the satin coloured silk yarn of multiple series, this kind can be used for high-grade suiting and fashionable dress lining.
The present invention has shortened technological process, enhances productivity, and has reduced production cost, makes that the spinning bar makes a good job of, filoplume is few, brute force is higher, and has abundant colors.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1 front roller, 2 two rollers, 3 middle rollers, 4 rear rollers, 5 decorative yarns, 6 basic yarns, 7 yarns, 8 feeding units.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises rear roller 4, middle roller 3, two rollers 2 and the front roller 1 that sets gradually, described rear roller 4 and middle roller 3 are provided with the feeding unit of being made up of lift spindle and horn mouth 8, the servomotor of control rear roller 4 is provided with the speed change intelligent controller, and the speed change intelligent controller is connected with encoder on being installed in front roller 1; Add on the delivery outlet of front roller 1 and have bothrium and the inner special pipe that is in negative pressure state, be arranged with grid ring on the special pipe, grid ring is drawn by roller.
Feed artificial example with three rove, a decorative yarn 5 is intermittently fed the people from rear roller 4, two foundation yarns 6 are fed the people continuously from middle roller 3, front roller 1 and 2 drawing-offs of two rollers through the proparea, to having bothrium and the inner shape tube (its surface is with grid ring, and grid ring is subjected to the delivery roller frictional drive) that is in negative pressure state, yarn 7 is subjected to suction function to be adsorbed on the position of the corresponding notch in grid ring surface, yarn 7 travels forward with grid ring when being gathered control, by the output of output jaw.Base yarn 6 usefulness gray yarns or shallow pattern gray yarn, single color yarn of decorative yarn 5 usefulness or colored yarn.The thickness of decorative yarn, length, interval are controlled with the method for technology, make a section decorative yarn present the color effect of satin on basic yarn.
The spinning technique main points are:
(1) hello people's regular roving feeding is lighter, and quantitative selection need be equipped with suitable roving twist factor could guarantee carrying out smoothly of half-finished quality and spinning;
(2) distance of two of spun yarn horn mouths is wanted selection less than normal;
(3) the spun yarn back zone drafting multiple suitably reduces, and is convenient to the feeding at intermittence of dyed yarn;
(4) apolegamy of spun yarn nip gauge piece should help the control of fiber and stablizing of drafting force, for the color yarn of satin, needs grasp bigger than normal, is preferably between average number and the basic yarn number number and selects;
(5) setting of spun yarn front roller speed is generally than common yarn low about 10%;
(6) rings, steel traveler are supporting.Rings is generally selected PG1 shaped steel neck for use, helps reducing the fluctuation of balloon tension size.The apolegamy of steel traveler is the difficult point of spinning, when between basic yarn number number and average number, selecting according to steel traveler weight, and often will be through repeatedly relatively determining that the cross sectional shape of steel traveler is advisable with height bow type repeatedly;
(7) spun yarn twist factor.Except that user's particular requirement, twist factor is generally high by about 10% than normal yarn;
(8) it is better to gather tension force 1.05, the too small district's fiber accumulations of gathering, and the part fiber is free state and is not involved in and forms filoplume, and the excessive district's fiber that gathers is straightened the back without gathering groove;
(9) gather vacuum at the 2000pa(70mm mercury column) about.For determining of negative pressure value, should with satisfy compacting effect, the minimizing filoplume is a principle, if negative pressure value is too small, does not have desirable compacting effect, Yarn filoplume can not reduce.If instead negative pressure value is excessive, no doubt may compacting effect even more ideal relatively, cause the consumption of the energy, the raising of cost but the vacuum motor load is excessive.Size for the negative pressure value between each ingot will guarantee unanimity in addition, and each ingot is pursued the ingot test to reduce the difference between ingot and the ingot;
(10) grid ring selects for use.Nylon monofilament is better, diameter 0.08, and 60/cm of density, voidage is 24 ~ 27%, the order number of grid ring is at 3600/cm
2The grid ring difference in length is in 1.4mm.
