雖然現在市場上環錠紡仍是主體，但轉杯紡經過40多年的發展，目前以紗線長度計算已占到紡紗總量的25%，以重量計算已占到40%。各類轉杯紗已成為紗線生產中的重要品種，其用途不斷擴大，轉杯紡紗已不再是棉紡廠的附屬車間與生產低檔紗的代名詞。
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.
技術發展迅速
Rapid technological development
經過40多年的發展，現在我國轉杯紡紗設備的數量與轉杯紗的產量已占全世界的1/3。轉杯紡產品也從初期的粗布、鞋面布、臺布等，發展到今天的牛仔布、燈芯絨、細布、針織品以及各種非棉產品等。
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.
浙江是我國轉杯紡紗生產大省，到2011年全省已擁有各類轉杯紡機40多萬頭，占全國轉杯紡產能的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.
紡紗優勢不可替代
Spinning advantages can not be replaced
與傳統環錠紡紗線產品相比，轉杯紡紗線有兩大特點：一是原料通過開清棉、梳棉及轉杯紡紗機等開松排雜裝置，可排除原料含雜總量的90%左右，因此，成紗含雜比普梳同號環錠紗要少。二是通過二道并條，可降低熟條的重不勻率，尤其在轉杯的凝聚過程中，可獲得較高倍的單纖維并合作用，因此，轉杯紗的長短片段不勻率明顯比環錠紗低。此外，與同號環錠紗相比，轉杯紗千錠斷頭降低約66.76%，織機產量提高約33.3%，坯布一等品率提高約l0%;而且轉杯紗結構蓬松，吸染率高，產品色澤鮮艷。
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.
轉杯紡流程更短，產能更高，在人工成本越來越高昂的今天，設備的自動化無疑是一種趨勢和解決問題的方法。轉杯紡是采用棉條直接紡紗并卷繞成筒子，省略了粗紗與絡筒兩個工序。設備減少，相應廠房面積與能耗也能節約，生產效率有較大幅度提高。以紡19.7tex紗為例，環錠紡的紡紗速度一般在20米/分左右，用半自動轉杯紡機紡紗速度可達到100~120米/分，分別是環錠紡的5~8倍。以每臺轉杯紡機裝360頭紡紗器計，半自動轉杯紡機5臺(1800頭)可達到環錠紡10000錠的生產量。
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.
轉杯紡在用工方面也比較有優勢。傳統環錠紡由于工序多、單機生產效率較低，手工操作比重大，故用工較多。而轉杯紡由于工序縮短、尤其全自動與半自動轉杯紡機使用后，使人工操作簡化、勞動強度降低，勞動生產率提高，故用工可以大幅度減少，按同等產量計算，轉杯紡可比環錠紡節約用工在50%左右，這使目前紡織企業用工多、招工難的矛盾可以得到一定程度的解決。
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.
近兩年，國內外棉價差成為困擾棉紡企業發展的重要因素。相對于環錠紡來說，轉杯紡可紡材料更為廣泛，從一定程度上解決了棉花成本高問題。轉杯紡紗原理為自由端紡紗，從條子到細紗在紡紗器中一次完成，故對纖維長度沒有環錠紡要求嚴格，棉、毛、絲、麻長度差異較大的短纖維及各類化學纖維均可在轉杯紡機上使用，同時在轉杯紡機的紡紗器中纖維有第二次開松除雜機會，故紡同號數的紗用較低等級原料仍可紡出好紗。
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.
從成紗質量指標分析：除單紗強力比環錠紗低10~15%外，其它如單紗強力不勻率、光潔度(毛羽數)與外觀疵點等轉杯紡紗均優于環錠紗。
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.
提升空間依舊巨大
Lifting the space is still huge
盡管轉杯紡相比較環錠紡有一些的優勢，但是其自身仍然存在提升空間。近來，我國的轉杯紡產品的開發領域不斷拓展，但主流產品主要集中在30支以下低支紗的加工，沒有明顯的競爭力。轉杯紡紗線產品只有努力創新，實現產品高檔化、差別化，才能在與“進口紗”的競爭中取勝。
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.
當前，我國轉杯紡非棉類產品的開發已經得到了很好的發展，但有業內人士認為，其開發前景還很廣闊。
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.
轉杯紡的原料資源很豐富，繅絲廠的下腳料、毛條廠的精落毛及短羊毛、苧麻紡紗廠的精落麻、次兔毛及棉型化纖等都可以用來作原料，轉杯紡對這些長度差異大、含雜多的原料具有良好的適應性。且轉杯紡適宜于生產粗支紗，而粗梳毛紗、苧麻紗等的紗號，正好適合轉杯紡的粗支紗范圍，而且號數越粗，產量越高，經濟效益越大。
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.
目前浙江省不少轉杯紡紗企業已先后開發生產中細號純棉低捻針織紗與粘纖針織紗等品種，由于紗線條干均勻、光潔度好、毛羽少、疵點少，有力地提高了針織物的實物質量與檔次，受到針織加工企業的普遍歡迎，其售價也可略高于環錠紡針織紗，為企業增加效益。
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.
