Description
Technical field
The present invention relates to the textile industry field, specifically be meant a kind of high-tenacity and low-tension spinning device that on traditional ring spinning yarn machine, adopts.
Background technology
Traditional ring spinning yarn machine is the main machine of spinning, the ring spinning technology maturation, the yarn variety wide adaptability, at present in the world the yarn total output about 60% by ring spinner production.
Along with the continuous expansion of textile fiber raw material range and the raising that the yarn qualities level is required, the ring spinning technology also faces problem demanding prompt solution.
1. the problem that ring spinning technology faces:
(1) incompatible to the fibrous raw material scope of continuous expansion
As; Polysulphonamide fiber is Shanghai City Spinning Science Institute stand-alone development and the organic high temperature-resistant fiber that has independent intellectual property right, is applicable to the goods of special high temperature-resistant requirement, but this fiber electrostatic phenomenon is serious; Cohesive force is less between fiber; The resultant yarn difficulty, and filoplume is many, utilizes existing ring spinning technology can not spin out desirable qualified polysulfonamide yarns.
The slubbing that and for example wool spinning spining semi-worsted yarn line china natural resources capable of using is abundant can be expanded raw material range so greatly and reduce cost of material with animal fiber raw material production knitting yarn.But slubbing is shorter with animal fiber raw material length, and the discrete length degree is bigger, adopts existing ring spinning technology spinning wool spinning spining semi-worsted yarn line difficulty big, and resultant yarn filoplume is many, and the PILLING RESISTANCE of its fabric is poor.
Ramee spinning for another example.China is the main ramie producing country in the world, and output accounts for 80% of Gross World Product.But the over-borrowing of ramie spinning machine is with wool spinning or cotton spinning ring throstle, and that the characteristic of ramee is a fiber is thick, and bending rigidity is big, and spinnability can not show a candle to wool fibre and cotton fiber, and existing ring spinning technology is incompatible to ramee.
(2) problem of ring spinning line quality level lifting
Actual production finds that in the ring spinner production process, same cop is inconsistent in little cop, middle cop and the yarn actual mass level in big cop stage; End breakage rate is the highest during the tubule yarn; In the cop end breakage rate minimum, be higher than middle cop again during big cop, three's end breakage rate ratio is 5: 2: 3.Be to improve the yarn quality level, must solve the cop produced with ingot in the mass discrepancy problem in large, medium and small cop stage, this also will realize by the performance of improving ring spinner.
Again, current a large amount of novel high speed looms are applied, but because the powerful weak ring and the filoplume problem of ring spinning line make loom broken yarn increased frequency under high-speed condition, do not reach loom high speed aim of high yield.
(3) high yield of ring spinning and power saving
At present; Actual ingot speed is produced in ring spinning can only reach 15000r/min, and half spinning actual ingot speed is 7000r/min, and the specified ingot speed of ring spinner is 22000r/min; The rated power of its motor fails to make full use of, and has caused the partial loss of electric energy.
Operating cost was spun in the spinning equipment configuration before the cotton spinning high efficient technology of just in the cotton spinning industry, promoting can reduce significantly before the reduction, improved spinning yarn quality, reduced the production management difficulty.Realize that high efficient technology requires the rove amount of resetting, spun yarn high draft, but outstanding problem such as the diffusion of yarn width increases under the existing ring spinner high draft condition, and it is many to produce resultant yarn filoplume, powerful low.
2. the defective of ring spinner itself:
(1) defective of three-dimensional twist triangle zone
Researching and analysing of ring spun yarn filoplume learnt; The twist triangle zone of ring spinning is not flat trigonum; Have an end of part fiber to be adhered to by rubber roll, roller in vertical direction, the other end links with the twisting sliver, constitutes three-dimensional twist triangle zone; The filoplume great majority that produce in this trigonum are for enclosing to filoplume, and the pilling influence to yarn strength and after processing fabric is very big.An above-mentioned end if its other end fails to combine with the main fibre of twisting sliver, is just become flyings by the fiber that rubber roll, roller adhere to; And if its other end combines with the theme fiber, under the forceful action of twisting sliver, can be stripped from and the spiral looping on the surface of resultant yarn yarn body, be prone to by friction and become card nailing neps.
(2) defective of high spinning tension and tension fluctuation
Ring spinner adopts steel steel traveler twisting mechanism, and air ring that it is exclusive and coiling form produce spinning tension and tension fluctuation.Spinning tension excessive and fluctuation can cause into sliver and do uneven, quality problems such as the thickness joint is many, broken end, and has limited the lifting of ingot speed and the raising of output.Spinning tension is made up of two parts: air ring centrifugal force F=m ω
2R and winding tension.Along with the variation of air ring size, promptly by of the variation of little yarn to big yarn, spinning tension from large to small, it is about 2 times of winding tension that the winding tension when spinning little yarn is big yarn.This spinning tension is excessive not to be well solved with the tension fluctuation problem so far as yet.
3. the problem that faces to above-mentioned ring spinning technology and the defective of ring spinner itself, many researchs are being engaged in the method and apparatus of the existing ring spinning condition of foundation improvement.Proposed denomination of invention like The Hong Kong Polytechnic University on April 24th, 2002 and be " sub-thread does not have the processing method and the equipment of torsion loop ingot yarn "; Application number is 02118588.3 Chinese invention patent application; Characteristic is that a false twister device is set between ring spinner front roller and steel traveler; False twister is made up of two semicircular body that have curved groove; Drive the fibre bundle twisting in the curved groove by the false twister rotation, fibre bundle is obtained and the reverse twist of resultant yarn, and finally be wound on the spool on the spindle of spinning machine.This curved groove false twister can strengthen the moment of torsion of yarn in the spinning triangular zone, improves yarn strength, can under the low twist coefficient condition, spin the yarn of spinning low twist.But because the limitation of this false twister device construction, the strength ratio traditional ring spinning resultant yarn of its resultant yarn is low by 18%, and percentage elongation is lower by 15.6% than traditional ring spinning resultant yarn, and the high-tension defective in the ring spinning technology is not solved at all.
