Description
Technical field
The present invention relates to the spinning technology field, relate more specifically to the complex yarn spinning technology of organic cotton model.
Background technology
In the tradition spinning process, think light quantitatively, jogging speed, low-producing spinning process be the inevitable approach that guarantees constant product quality, still this steady quality is to be cost than higher input cost and lower output benefit.In recent years, closely spinning process, match network spinning process and the amount of resetting high efficient technology have become the focus of cotton spinning industry and the topic that merits attention.Three kinds of spinning techniques respectively have pluses and minuses, the spinning principle of three kinds of technologies of following brief introduction:
One, tight spinning process spinning principle
The spinning principle of closely spinning is to increase a condensation region between the draw zone of traditional ring throstle and twisting area, utilize negative pressure air that fiber is produced pneumatic concentration effect, those fibre ends that are on the yarn edge can be assembled to the yarn center effectively, finally reduce spinning triangular zone to greatest extent.The effect of this coacervation process makes filoplume minimizing significantly, the single thread force of resultant yarn and extension at break significantly improves, the normal property the sent out fault of resultant yarn also obviously reduces.And the clear and fineness of the friction factor of yarn, the glossiness of fabric, surface-defect number, wear-resistant degree and dyeing etc. has all had the improvement of matter.
But closely the spinning equipment capital fund is big, and the fixed cost height has increased the equipment investment of cotton mill.Except the fibrous index part that has greatly improved, improvement amplitudes such as other index of yarn such as bar do, thick, details are little.
Two, match network spinning process spinning principle
It is to feed two rove with certain spacing on same ingot position that the match network spins, and two rove are drafted respectively, and sliver is after front roller output, because the effect of twisting, two slivers form a spun yarn by twisted together.The sliver that the match network spins is not twisted substantially at the front roller nip place, so there be not so-called " twist triangle zone ", has significantly reduced the flyings in workshop, and through behind the winding procedure, the hairiness ratio compact spinning of match doff still less.The match doff is in twisting process, and the inside and outside degree that shifts of drawing-off is little, fiber alignment rule behind the resultant yarn, and its yarn strength is better than single thread, matches the network spinning technique up to now and is used widely in cotton spinning wool spinning bast fibre spinning system.
But, match network spinning process also has its weak point: in match network spinning process, the drawing-off state of single rove is the twice of the spun yarn number that spins, match the quantitatively little a lot of than traditional spinning process usually of network spinning process, increased the pressure of rove operation greatly, spin the performance of efficient before the influence, cause multipurpose device, many recruitments.To the sliver of twisted point section, fiber number is that half of number of fiber on the spun yarn cross section spun by institute at front roller nip, if raw material is too poor or technological parameter is selected improperly, can increases spinning and breaking end, even can't normally spin.
Three, the efficient spinning process principle of the cotton spinning amount of resetting
The amount of resetting high efficient technology is meant on modern spinning equipment, initiatively bring into play the potential of modern novel device,, spun the amount of resetting before realizing with equipment and the specially technological progress drive process innovation application of part, the spun yarn high draft is main high efficiency, the spinning unit engineering of high benefit.High efficient technology has been broken through the theory and practice application of traditional spinning process, and a kind of resource-effective new pattern of management has been explored by enterprise for spinning, and the new way of a profit growth is the inexorable trend of spinning process research from now on.High efficient technology reduce recruitment and reduce production costs playing a key effect, so high efficient technology has higher popularization and application values to improving board output, significantly reducing preceding spinning equipment board.
But, after the rove amount of resetting spun yarn high draft is particularly adopted in the application of high efficient technology, coarse yarn density increases, and the width of feeding drawing-off part yarn is increased, and enters the proparea yarn after the little twist of rove and more curries favor with non-twist, yarn is easy to disperse, the proparea drawing-off that spun yarn is bigger makes the yarn divergent trend more obvious, and the yarn twist triangle zone is increased, and filoplume increases, thereby adopt such technology resultant yarn filoplume more, be unfavorable for the processing of later process.
Present organic cotton model blended yarn uses RING SPINNING, closely spin, match network spins a kind of spinning method wherein or closely spins and match network and spin the spinning method that combines and spin, the application of these methods all has its one-sidedness: (1) uses the traditional ring spinning yarn process, adopt light quantitatively, jogging speed, low-producing spinning process guarantee constant product quality, but this steady quality is to be cost than higher input cost and lower output benefit, and resultant yarn filoplume H value is higher, powerful low, wear no resistance, influence the wearability of its yarn.(2) use and closely to spin, to match network and spin a kind of spinning method wherein or closely spin with matching network and spin the spinning method that combines, resultant yarn filoplume H value is lower, but the equipment investment cost height, technical cost and energy consumption are big, and production efficiency is low.
