Technical field
The present invention relates to the friction spinning technology field, is a kind of conveying and condensing method of friction spun yarn specifically.
Background technology
Since the self-friction spinning is come out, once caused domestic and international researcher's great attention.The up-and-coming youngster who once had been considered to novel spinning is one of the most promising novel spinning.But, owing to the early stage friction spinning machine carrier pipe space structure vertical with dust cage limit, the straightening of fibers degree extreme difference in institute's yarn, quality of yarn particularly yarn texture can not reach gratifying effect always.The conveying of tradition friction spun yarn, one leans on the centrifugal force of machinery (combing roller) that filament is thrown to cotton delivery pipe, and two lean on air-flow tangentially to import the comb and parallel cotton fibers prior to spinning pipeline along combing roller.The air-flow of Xing Chenging can not make straightening of fibers like this, but curl.Therefore the yarn texture disorder that traditional friction spinning machine is produced can not high-count yarn spun.Friction spun yarn is a kind of open-end-spinning, and it is carried with cohesion is the key of spinning, and it has determined the permutation and combination and the structure of fiber, thereby has also just determined quality of fibre.Therefore, in the decades in past, the focus of those skilled in the art of the present technique's research concentrates on its key position always---twisting and cohesion aspect, and in the hope of obtaining straightening of fibers degree and higher spinning count preferably.
In order to reach straightening of fibers degree preferably, except improving the combing roller carding effect, also to improve shape, the structure of carrier pipe.For example, the DREF2 type of Filler company adopts balance pawl formula disk, attempts fiber is pushed the parallel direction conveying by the vertical direction conveying, thereby makes parallel the stretching of fiber in the resultant yarn.But because fiber is soft, so effect is unsatisfactory, this equipment is never applied.
Domestic weaving universities and colleges and research institution once changed the vertical transport pipe of Filler company, became incline direction and carried, and does not wait from 45 ° to 10 ° at the angle of inclination, though yarn qualities has certain improvement, can not deal with problems at all.
More than these researchs all be " straight line conveying " mode that adopts fiber, its basic premise is, fiber is a rigid body, the motion in course of conveying meets the movement of Rigid Body rule.But in fact fiber is a flexible body, very easily distortion (particularly flexural deformation) in motion process.According to this inherent characteristic of fiber, it is parallel to adopt " straight line conveying " to be difficult to make fiber to stretch in the carrier pipe flow field, obtains the yarn of fiber along yarn axle orientation.How, study a kind of conveying and condensing method of friction spun yarn,, become the urgent problem that solves of present needs to obtain straightening of fibers degree preferably and to spin yarn than high-count according to the inherent characteristic of fiber.
Summary of the invention
The objective of the invention is to provide a kind of conveying and condensing method of friction spun yarn, can obtain straightening of fibers degree preferably, obtain the yarn of fiber, can spin yarn than high-count along yarn axle orientation at the deficiencies in the prior art.
The objective of the invention is to be achieved through the following technical solutions: a kind of conveying of friction spun yarn and condensing method, it is characterized in that: wind-supplying mouth is axially mended wind along combing roller on the combing roller casing, make and form eddy flow in the reducing pipe, under the rotating jet effect of mending the circumferential air-flow formation of general mood stream and combing roller, divided the single fiber of combing to enter the transfer passage that the employing pair of plates is formed the gap convergent by combing roller, fiber is fed forward with the hand of spiral, and constantly increase radius of turn, under the constraint of dull and stereotyped transfer passage, fiber becomes ellipse by circle, minor axis constantly shortens then, reach parallel stretching fully at last in dull and stereotyped transfer passage exit, send into the condensation region, and condense in yarn with the direction parallel with collection surface.
In said method, the two dull and stereotyped spacings that form transfer passage are dwindled gradually by the outlet that enters the mouth, and two dull and stereotyped porch spacings are 1.5-3 times of two dull and stereotyped exit spacings.
In said method, the width that forms two flat boards of transfer passage is broadened gradually by the outlet that enters the mouth, and the width in dull and stereotyped exit is 3-5 a times of porch width.
In said method, break away from needle point in order not damage fiber and to be convenient to fiber, adopt card wire formula combing roller that fiber is carried out the branch comb.
For make benefit wind be controlled at the wind-supplying mouth place as far as possible, the gap between combing roller housing and the combing roller is less than 0.01mm.
The present invention compared with prior art has many advantages and good effect:
1, one of key of the present invention is the change of wind-supplying mouth on the combing roller housing, and the wind mode is mended at original rear portion, changes combing roller into and axially mends wind.Wind-supplying mouth and combing roller are axial benefit wind, then are tangential benefit wind along the axial benefit wind of combing roller for reducing pipe.Therefore, because the circumferential air-flow that the combing roller revolution causes is synthetic with benefit general mood stream, in carrier pipe, form spiral air flow.Two of key of the present invention is to adopt parallel-plate, convergent, open carrier pipe.Spiral air flow integrates the flow field form of rotating jet, free jet, parallel-plate jet under the restriction of parallel-plate carrier pipe, finally reach to stretch, condense upon abreast on the yarn tail with dust cage axial (yarn direction of principal axis), forms " parallel cohesion ".Obtained straightening of fibers degree preferably, obtained the yarn of fiber, be fit to spin yarn than high-count along yarn axle orientation.
2, technology of the present invention is reasonable, and the scrap build cost is lower, helps promoting.
