虽然现在市场上环锭纺仍是主体，但转杯纺经过40多年的发展，目前以纱线长度计算已占到纺纱总量的25%，以重量计算已占到40%。各类转杯纱已成为纱线生产中的重要品种，其用途不断扩大，转杯纺纱已不再是棉纺厂的附属车间与生产低档纱的代名词。
Although now market ring spinning is still the principal, but transferred to the spinning after 40 years of development, currently in the yarn length calculation has accounted for 25% of the total spinning, weight calculation has accounted for 40%. All kinds of rotor spun yarn has become the important varieties in yarn production, its usage is expanding, rotor spinning is no longer synonymous with cotton spinning factory affiliated workshop and the production of low-grade yarn.
技术发展迅速
Rapid technological development
经过40多年的发展，现在我国转杯纺纱设备的数量与转杯纱的产量已占全世界的1/3。转杯纺产品也从初期的粗布、鞋面布、台布等，发展到今天的牛仔布、灯芯绒、细布、针织品以及各种非棉产品等。
After more than 40 years of development, the number of rotor spinning equipment and rotor spinning yarn production has accounted for of the world's total. Rotary cup spinning products also from the initial coarse cloth, shoe cloth, table cloth, and so on, development to today's denim, corduroy, linen, knitted fabrics and a variety of non cotton products.
浙江是我国转杯纺纱生产大省，到2011年全省已拥有各类转杯纺机40多万头，占全国转杯纺产能的1/8左右。
Zhejiang is of rotor spinning production of a large province in China, in 2011 the province has all kinds of rotary cup spinning machine more than 40 million head, accounting for about 1 / 8 of the rotor spinning capacity.
纺纱优势不可替代
Spinning advantages can not be replaced
与传统环锭纺纱线产品相比，转杯纺纱线有两大特点：一是原料通过开清棉、梳棉及转杯纺纱机等开松排杂装置，可排除原料含杂总量的90%左右，因此，成纱含杂比普梳同号环锭纱要少。二是通过二道并条，可降低熟条的重不匀率，尤其在转杯的凝聚过程中，可获得较高倍的单纤维并合作用，因此，转杯纱的长短片段不匀率明显比环锭纱低。此外，与同号环锭纱相比，转杯纱千锭断头降低约66.76%，织机产量提高约33.3%，坯布一等品率提高约l0%;而且转杯纱结构蓬松，吸染率高，产品色泽鲜艳。
Compared with the traditional ring spinning yarn products, spinning line has two characteristics: one is the raw material through the opening and cleaning cotton, carding and spinning machine, loosen the impurity removing device, may be excluded from the raw material impurity containing 90% of the total about. Therefore, yarn containing mixed BiP comb with the number of ring spun yarn. Second by second drawing can reduce sliver weight unevenness rate, especially in the rotor in the coagulation process can obtain high times of single fiber and, therefore, to turn spun yarn fragment length uneven rate significantly lower than ring - spun yarn. In addition, compared with the same number of ring spun yarn, rotor spun yarn thousand ingots breakage reduce about 66.76%, loom production increased by about 33.3%, fabric for first-class rate increases by about l0%; and turn spun yarn fluffy structure, ceiling high dyeing rate and product color bright.
转杯纺流程更短，产能更高，在人工成本越来越高昂的今天，设备的自动化无疑是一种趋势和解决问题的方法。转杯纺是采用棉条直接纺纱并卷绕成筒子，省略了粗纱与络筒两个工序。设备减少，相应厂房面积与能耗也能节约，生产效率有较大幅度提高。以纺19.7tex纱为例，环锭纺的纺纱速度一般在20米/分左右，用半自动转杯纺机纺纱速度可达到100~120米/分，分别是环锭纺的5~8倍。以每台转杯纺机装360头纺纱器计，半自动转杯纺机5台(1800头)可达到环锭纺10000锭的生产量。
Rotor spinning process is shorter, the production capacity is higher, the labor cost is more and more high today, the automation of the equipment is no doubt a trend and solve the problem of the method. Rotor spinning is the direct spinning sliver and rolled into a bobbin, and omit the roving winding two process. Equipment is reduced, the corresponding plant area and energy consumption can also be saved, and the production efficiency is greatly improved. To kind of yarn spinning, for example, ring spun spinning speed general at 20 m / min or so, with semi automatically turn cup spinning machine for spinning speed can reach 100 to 120 m / min, respectively, the ring spinning in the 5 to 8 times. On each turn cup spinning machine installed 360 head spinning device, semi automatic rotor cup spinning machine 5 sets (1800) ring spun 10000 spindles of production can be achieved.
转杯纺在用工方面也比较有优势。传统环锭纺由于工序多、单机生产效率较低，手工操作比重大，故用工较多。而转杯纺由于工序缩短、尤其全自动与半自动转杯纺机使用后，使人工操作简化、劳动强度降低，劳动生产率提高，故用工可以大幅度减少，按同等产量计算，转杯纺可比环锭纺节约用工在50%左右，这使目前纺织企业用工多、招工难的矛盾可以得到一定程度的解决。
Rotor spinning in labor also has advantages. Because of the process of the traditional ring spinning, the single machine production efficiency is low, the manual operation is more important, so it is more and more important. And spinning due to working relationship, especially automatic and semi automatically turn cup spinning machine use, the manual operation simplified, reduce labor intensity, improve labor productivity, so employment can greatly reduce, calculated according to the same output, rotor spinning can than ring spinning saving labor in 50% the left and right, this makes the textile enterprises, employment, recruitment difficulties contradiction can be resolved to a certain extent.
近两年，国内外棉价差成为困扰棉纺企业发展的重要因素。相对于环锭纺来说，转杯纺可纺材料更为广泛，从一定程度上解决了棉花成本高问题。转杯纺纱原理为自由端纺纱，从条子到细纱在纺纱器中一次完成，故对纤维长度没有环锭纺要求严格，棉、毛、丝、麻长度差异较大的短纤维及各类化学纤维均可在转杯纺机上使用，同时在转杯纺机的纺纱器中纤维有第二次开松除杂机会，故纺同号数的纱用较低等级原料仍可纺出好纱。
In recent years, domestic cotton price difference has become an important factor in the development of cotton spinning enterprises distress. Compared with ring spinning, rotor spinning can be more widely used, and it can solve the problem of high cost of cotton in a certain extent. Turn spinning principle for free end spinning, from note to spinning in spinning is a complete and so on fiber length did not ring spinning strict requirements, cotton, wool, silk, linen, differences in the length of the larger short fiber and all kinds of chemical fiber can be in the rotary cup spinning machine use, also in turn cup spinning machine for spinning fiber is the second open pine impurity opportunity, so spinning with tex yarn with lower grade raw materials still spinning yarn.
从成纱质量指标分析：除单纱强力比环锭纱低10~15%外，其它如单纱强力不匀率、光洁度(毛羽数)与外观疵点等转杯纺纱均优于环锭纱。
From the yarn quality index analysis: in addition to single yarn strong than the ring spun yarn low 10-15% and other such as single yarn powerful unevenness, finish (hairiness) and appearance defects, such as turn spinning were better than ring spun yarn.
提升空间依旧巨大
Lifting the space is still huge
尽管转杯纺相比较环锭纺有一些的优势，但是其自身仍然存在提升空间。近来，我国的转杯纺产品的开发领域不断拓展，但主流产品主要集中在30支以下低支纱的加工，没有明显的竞争力。转杯纺纱线产品只有努力创新，实现产品高档化、差别化，才能在与“进口纱”的竞争中取胜。
Although the rotor spinning has some advantages compared with ring spinning, there is still room for improvement. Recently, China's development of rotor spinning products continue to expand, but the mainstream products are mainly concentrated in the following 30 low yarn processing, there is no obvious competitive. Rotor spinning line products only to innovation, to achieve high grade products, differentiation, in order to win the competition with the imported yarn.
当前，我国转杯纺非棉类产品的开发已经得到了很好的发展，但有业内人士认为，其开发前景还很广阔。
At present, the development of rotor spinning non cotton products in China has been well developed, but the industry believes that its development prospects are very broad.
转杯纺的原料资源很丰富，缫丝厂的下脚料、毛条厂的精落毛及短羊毛、苎麻纺纱厂的精落麻、次兔毛及棉型化纤等都可以用来作原料，转杯纺对这些长度差异大、含杂多的原料具有良好的适应性。且转杯纺适宜于生产粗支纱，而粗梳毛纱、苎麻纱等的纱号，正好适合转杯纺的粗支纱范围，而且号数越粗，产量越高，经济效益越大。
Rotary cup spinning raw material resources is very rich, reeling mill of scraps, wool top factory fine falls the essence of noil hair and short wool, ramie spinning mills, rabbit hair and cotton type chemical fiber can be used as raw material, rotor spinning on these differences in the length of the large, containing heteropoly materials with good adaptability. And turn spinning is suitable for the production of coarse yarn, and carded yarn, wool yarn, ramie yarn, just right for rotor spinning coarse yarn range, and Tex thicker, higher yield, economic benefits.
目前浙江省不少转杯纺纱企业已先后开发生产中细号纯棉低捻针织纱与粘纤针织纱等品种，由于纱线条干均匀、光洁度好、毛羽少、疵点少，有力地提高了针织物的实物质量与档次，受到针织加工企业的普遍欢迎，其售价也可略高于环锭纺针织纱，为企业增加效益。
The Zhejiang Province, a lot of rotor spinning enterprise has development and production of fine cotton low twist knitted yarn and Viscose Knitting Yarn varieties, due to yarn evenness, smoothness is good, less hairiness, fewer defects, effectively improves the knitted fabric with the physical quality grade by knitting processing enterprises generally welcomed, the price can also be slightly higher than ring spinning knitting yarn, for enterprises to increase efficiency.
