TW Special Report CITME 2002Increases in visitors, exhibitors and exhibition area at CITME 2002 reflect the successful expansion of China’s textile industry. Since its first edition in 1988, the scale of the China International Textile Machinery Exhibition (CITME) has been increasing steadily in terms of exhibitors, visitors and exhibition area. China is the top producer and exporter of textile and apparel products worldwide, and its installed capacity is represented by 34 million short-staple and 3.6 million long-staple spindles.But the future success of China’s textile industry is strictly connected to its capacity for renovation, in terms of both organization and technology. The entry of China into the World Trade Organization (WTO) and the signing of the Agreement on Textiles and Clothing imply a complete liberalization of the textile market by 2005.At CITME 2002, about 90 Italian textile machinery producers exhibited in an area measuring 1,700 square meters. Asia once again is the main destination for Italian textile machinery, as is confirmed by its 37-percent share of total Italian exports. The Italian presence at CITME is part of an active global promotional program that the Italian Association of Textile Machinery Producers (ACIMIT) and the Italian Trade Commission (ICE) have been carrying out for many years.The French Textile Machinery Manufacturers Association (UCMTF) also was present at CITME 2002, promoting the products of such companies as Asselin, Laroche S.A., Superba S.A., Thibeau and N. Schlumberger & Cie. Fiber Preparation & SpinningGermany-based Trützschler GmbH & Co. KG offered its installations for spinning preparation, from bale to sliver. The product range includes the Blendomat® BDT automatic bale opener, which provides a gentle uniform opening and processes up to 1,500 kilograms per hour (kg/hr). The Securomat SCFO foreign part separator, used directly after the bale opener, protects the cleaning line from damage, detects metal parts and separates the parts into a waste carriage. Trützschler’s Multi-mixer MCM mixing system offers an optimal solution for any textile manufacturer, and for any mixing task in the field of one-component staple fiber mixes. The high-production card DK 903, representing a further development of the DK 803, has been designed to improve carding quality even more.Rieter Spun Yarn Systems, Switzerland, presented its new and innovative rotor core yarn system, Rotona®. Rotona rotor core yarn, a novelty in the yarn market, combines the advantages of a rotor yarn with the numerous possibilities of a core yarn.
Heinrich Trützschler (left), managing director, Trützschler GmbH & Co. KG, and Xu Kunyuan, CITME Rotona core yarns have a stable structure in which the rotor yarn is wrapped around the core. The yarns also exhibit low yarn unevenness and reduced hairiness. New features offered on the Rieter BT 903 and BT 905 include a machine length of up to 320 rotors and rotor speeds of up to 100,000 revolutions per minute (rpm). Also, the spinning units can now be equipped with a new type of rotor in conjunction with an enhanced external suction device. Another Rieter highlight was its new R40 rotor spinner, a result of the successful cooperation that started last year with the Germany-based Suessen Group. The R40 combines the machine and transport automation concept of Rieter’s R20 with Suessen’s SC-R spin box technology. Rotor speeds of up to 150,000 rpm and delivery speeds of up to 235 meters per min (m/min) underline the high productivity potential of the R40.Suessen already has modernized more than 50,000 ring-spinning frames and roving frames with HP top arms, roller stands, bottom rollers with bearings, top rollers with cots, bottom apron guide bars, cradles and aprons, among others. The Compact SC 2-M SpinBox has been specially designed for spinning synthetic fibers.In the Chinese market, Suessen’s HP-A 310 Top Weighting Arm for short-staple spinning has enjoyed great success, with a few hundred thousand positions sold and installed. Improved yarn quality has been the decisive argument for customers.
