ith ITMA Asia + CITME 2010 coming in June, spinning and twisting machinery manufacturers
will be introducing new technologies for both the Asian and overall global markets. Following is a
sampling from four suppliers.
Trützschler
Trützschler Spinning and Trützschler Card Clothing (TCC), two of three businesses comprising Germany-based Trützschler GmbH & Co. KG, provide technology and machinery for spinning preparation.
Trützschler Spinning is putting emphasis on its foreign parts detection and separation technology. The top-of-the-line Securoprop SP-FPU detects foreign parts - including colored, transparent and partially transparent parts - using polarized light, and is particularly effective for detecting materials such as polypropylene or polyethylene foil, which - though similar to cotton in color - are not detected by conventional foreign part separators.
TCC reports its new FGX1 cylinder card clothing for spinning noticeably improves the quality of combed yarns, even when installed on older cards and with lower production rates than are achieved using newer cards. The company also notes that the clothing lasts up to 30-percent longer than earlier varieties and requires half the maintenance.
The FGX1 cylinder wire features a new tooth shape and offers a soft carding process. It also reduces imperfection indicator (IPI) values by 15 percent, and reduces neps by up to 90 percent.
Rieter
Rieter Machine Works Ltd., Switzerland, is promoting its RSB-D 22 double-head autoleveler draw frame and its new G 32 ring-spinning machine. Edda Walraf, the company's head of marketing, reports both machines are designed to provide high- and consistent-quality short-staple yarns made of 100-percent cotton, man-made fiber and blends of the two.
The RSB-D 22, with 2 x 1,100-meters-per-minute (m/min) maximum delivery speed, and RSB-D 22c for combed cotton, with 2 x 550-m/min maximum speed, feature two completely independent machine sides and autoleveling functions, with quality and output of each head comparable to that of Rieter's RSB-D 40 single-head draw frame. Advantages of the double-head model include reduced space requirements, low energy consumption owing to joint utilization of one extraction fan for both heads, and reduced capital cost. The independent machine sides also improve efficiency by 10 to 15 percent over conventional double-head draw frames and produce superior sliver quality as there is no coupled delivery roller drive as is typical on other draw frames, Walraf said. Flexibility is enhanced because each machine side can be set for different sliver weights and speeds. Space-saving features include machine widths of 320 centimeters (cm) for the RSB-D 22 and 290 cm for the RSB-D 22c; and the option of setting the machine into the floor, which reduces its length by 1 meter or so. Also, large sliver feed cans can be arranged in three rows instead of two to reduce roller feed length.
The G 32 features up to 1,440 spindles, reducing investment costs per spindle. Other features include: Rieter's Ri-Q-Draft drafting system, which, according to Rieter, improves yarn quality owing to effective fiber guidance and spinning geometry; ROBOdoff offering short doffing cycles and operating in combination with SERVOdisc cops and tube transport and handling system; and SERVOgrip to eliminate underwound threads and reduce fiber fly. The machine also offers flexibility to adapt twist and yarn feed from the control panel. Additional programming from the control panel can reduce doffing ends down, and optimized speed curves minimize spinning ends down. Machines with more than 1,200 spindles offer a FLEXIstart option to start the machine in two halves.
Oerlikon Schlafhorst
Germany-based Oerlikon Textile GmbH & Co. KG's Oerlikon Schlafhorst business unit offers several new rotor- and ring-spinning and winding technologies.
The BD 416 rotor-spinning machine, the latest generation of the company's BD series, has up to 416 spinning units and an electronically controlled high-precision drive system. The company reports that, with its high take-up speed, the machine's productivity surpasses that of comparable rotor-spinning machines; and that it takes up less space than comparable machines despite the fact that it has more spinning units.
The Zinser 351 Impact FX compact ring-spinning machine features up to 1,680 spindles, making it the longest compact spinning machine made and optimizing cost and space efficiencies, Oerlikon Schlafhorst reports. Efficiency also is enhanced by the machine's independently adjustable vacuum unit that is detached from the yarn breakage suction; automatic self-cleaning, facilitated by the apron design and material choice for the unit; and straight airflow through the system, which eliminates clogging from particles being caught in corners or bends. The machine can process all fiber types and blends, with settings for different fibers managed using the EasySpin touchscreen.
Oerlikon Schlafhorst's new Autoconer X5 winder features enhanced automation and flexibility. The company reports customers may use either traditional drum-winding systems, or drumless systems with PreciFX using Speedster FX to raise productivity and/or yarn quality. The winder also features a new X-Change doffer with expanded functionality, flexibility and speed; Plug&Wind and CAN bus technology; simplified operation; and low energy consumption.
Savio
Italy-based Savio -- doing business as Savio Macchine Tessili S.p.A. and comprising the spinning brand of Itema Group's Itema Spinning subsidiary -- is promoting the Polar I/DLS (direct link system), the newest model in its Polar line of automatic link winders, which are available in a range of configurations with up to 72 drums. The company, which first introduced its Polar winders in 2006 to meet the needs of spinners in the Far East, reports the new model offers affordability and simple but sophisticated operation for an industry that is becoming increasingly modernized.
Savio's Polar I/DLS link winder features a modular, high- efficiency bobbin processing system.
The Polar I/DLS features an innovative closed-loop spinning frame-to-winder feeding system that allows materials to move completely freely through the system, according to Savio. No hands touch the yarn as it is processed from the speed frame bobbin to the final package, thereby reducing material handling and eliminating possibilities of contamination while maximizing quality. The winder also features a modular, high-efficiency bobbin processing system; and the spindle now has a straightened yarn path, with two additional bobbins lined up ready for winding at each spindle. The suction unit is driven by a high-efficiency inverter, minimizing energy consumption, and a fully integrated, self-adjusting suction management system creates optimal suction based on the machine's actual requirements. This feature, coupled with the spindle's Flexycycle, minimizes hard waste, Savio reports.
Other features of the Polar I/DLS include: electronic anti-patterning device for improved package formation; computer-aided tension to equalize yarn tension on the package; and computer-aided metering to minimize metering differences and equalize package density.

纺纱及加捻创新技术
从纺纱前准备到络纱，《亚洲纺织世界》为您带来一些纺纱行业的最新技术。
Janet Bealer Rodie，《纺织世界》执行主编
随着6月中国国际纺织机械展览会暨ITMA亚洲展览会的临近，纺纱及加捻机械制造商将为亚洲以及全球市场推出新的技术。下面是从四个供应商来的采样。
特吕茨勒
特吕茨勒纺纱和特吕茨勒针布（TCC）是德国特吕茨勒公司旗下三大业务中的两块，提供的是纺纱前准备技术及机械。
特吕茨勒纺纱将它的重点放到了外来物质检测和分离技术上。最高级的Securoprop SP-FPU能够检测的外来物质包括染色的、透明的以及部分透明的物质。它使用偏振光，对
于检测诸如聚丙烯或聚乙烯箔等材料特别有效--即使这些材料与棉的颜色相似。而之前用传统的外来物质分离器是检测不出来的。
特吕茨勒针布称，它的用于纺纱的新型FGX1圆筒针布显著的提高了精梳棉的质量，甚至安装在一台旧的、生产率比不上新机器的梳理机上，也有同样的效果。该公司还表示，这
种针布比之前的各种布最多要长30%，而只需一半的维护工作。
FGX1圆筒针基具有新的筘齿形状，支持柔和的梳理加工。它的缺陷指标（IPI）值减少了15%，最多还可以减少90%的线头。
立达
瑞士立达机械公司正在推广它的RSB-D 22双头自动匀整并条机，及它的新型G32环锭细纱机。该公司营销部门负责人Edda Walraf表示，这两种机器都专为以100%棉纤维、人
造纤维或混纺纤维为原材料生产优质并始终如一的短纤纱线而设计。
RSB-D 22最大传输速度为每分钟2x1100米；而RSB-D 22c用于生产精梳棉，速度最高为每分钟2x550米，具有2个完全独立的机面和自动匀整功能，且
每个头的质量和产量与立达的RSB-D 40单头并条机都不相上下。这种双头型号机器的优势包括减少了空间要求，而且由于两个头联合使用一个 抽风机而降低了能耗，以及减少了人工成本。据Walraf介绍，独
立的机面与传统的双头并条机相比，效率也提高了大约10-15%；与其它典型的并条机不同，由于没有偶联输送罗拉驱动，生产出来的梳条质量非常好。因为每个机面可以设置不同的梳条重量和速度，灵活性也提高了。减
少空间体现在RSB-D 22的机械宽度是320厘米，RSB-D 22c的宽度是290厘米；在将机器安装到地板上时，长度减少了1米左右。此外，大的梳条喂纱可以安排3行而不是2行，以减少罗拉喂料长度。
G32的特点是长达1440锭，减少了在每锭上的投资。其它特点包括：立达的Ri-Q-Draft牵伸系统，据立达称，由于有效的纤维导向和纺纱几何学，它能够提高纱线质量；R
OBOdoff支持短的落纱循环，结合SERVOdisc管道传输和控制系统进行操作；SERVOgrip消除了欠卷绕线条，并减少了纤维漂浮。该机器还能够灵活的适应从控制仪表上传来的加捻和纱线喂给指令。在
控制仪表上进行额外的编程能够减少落纱的断头，优化了的速度曲线可最大程度的减少纺纱的断头。带有超过1200锭的机器可以通过选择安装FLEXIstart分成两半启动机器。
立达的RSB-D 22双头自动匀整并条机的最大输送速度达到了每分钟2 x1100米，在节省空间的同时减少了相关的成本。
欧瑞康Schlafhorst
德国欧瑞康纺织机械公司旗下的欧瑞康Schlafhorst部门将推出几种新的气流纺、环锭纺和络纱技术。
BD 416气流纺机是该公司BD系列的最新型号，带有最多416个纺纱部件和一个电子控制的高精度驱动系统。该公司称，通过它的高速卷取，该机器的生产力超过同类型的气流纺机；同时，虽 然它有更多的纺纱组件，但与同类机械相比占用的空间更小。
青泽351 Impact FX紧密环锭纺机最多可以达到1680锭，据欧瑞康Schlafhorst公司称，这使它成为最长的紧密纺机，优化了成本并节约了空间。通 过该机器从纱线断头吸取处分离出的可独立调节的真空部件，效率得到了提高；通过组件的皮圈设计和材料选择加速了自动的自清洗；通过该系统的连续气流，消除了在角落里或弯头处接住的颗粒造成的堵塞。通 过使用EasySpin触摸屏设置不同纤维参数，该机器能够加工所有类型的纤维和混纺物。
欧瑞康Schlafhorst的新型Autoconer X5络纱机的自动化以及灵活性都得到提升。该公司称，客户能够将利用Speedster FX提高生产力以及纱线质量的PreciFX，与 传统的槽筒络筒系统或无滚筒系统配合使用。这种络纱机的特点还包括，新的带有更多功能、更具灵活性和更高速度的X-Change小滚筒；Plug&Wind 和 CANbus技术；并且简化了操作，降 低了能源消耗。
萨维奥
意大利萨维奥公司，暨萨维奥机械公司，它旗下的纺纱业务部门意达集团的意达纺纱公司推出了Polar I/DLS--这是它的Polar自动连杆络纱机产品线上的最新型号，它有一系列规格，最 多可带72个滚筒。该公司早在2006年首次推出它的Polar络纱机，以满足远东地区纺纱厂的需求。它表示，新型机器价格适中，对于一个变得日趋现代化的行业来说，操作简单但要求精密。
萨维奥的Polar I/DLS连杆络纱机具有一个模块化的高效络筒加工系统。
据萨维奥公司介绍，Polar I/DLS的特点包括一个创新的闭环式从纺纱筒到络纱机的喂料系统，它可以允许原料通过这个系统完全自由的移动。由于加工从粗纱机筒子到最后的包装都无需手的接触，由 此减少了原料在手工处理时被污染的可能性，从而最大限度提高了质量。该络纱机的特点还有，一个模块化的高效络筒加工系统；纺锭现在有一个校直的纱线路径，每个纺锭上有2个额外的络筒排好队等待络纱。抽 吸装置是通过一个高效变频器来驱动，最大限度减少能源的消耗，一个完全集成、可自我调整的抽吸管理系统基于该机器的实际要求能创造出最佳的抽吸效果。据萨维奥介绍，这一特点，结 合这种纺锭的Flexycycle功能，最大限度减少了回丝。
Polar I/DLS的其它特点还包括：电子防重叠装置，可以提高包装成形；电脑辅助张力，可以均衡包装中纱线的张力；电脑辅助计量，可以最大限度减少计量误差，并均衡包装密度。
