Rotor spinning machines for Pakistan market
by
Waltraud Jansen, Schlafhorst

The textile industry of Pakistan has over 140,000 installed rotor spinning positions. Almost all the machines that were installed during the past seven years bear the name of Autocoro. As in the other countries of the world, Autocoro yarns also in Pakistan are synonymous with high quality and economic efficiency, both in spinning and in the subsequent textile production processes.

As in the past, the Autocoro yarns produced in Pakistan today are predominantly used for denim. Nevertheless, the demand for Autocoro yarns for single jersey for T-shirts and underwear as well as for coarse knitted goods of fibre-blend yarns for leisure

wear is on the rise. The great potentials for rotor yarns in the fields of medium-fine yarns, for instance for terry articles, and of fine-count yarns attract growing interest. It can safely be assumed that with the broad range of applications and the high economic efficiency of the rotor yarns, the growth of the installed basis of Schlafhorst rotor spinning machines in Pakistan will continue.

The new automatic rotor spinning machine Autocoro 360 is the answer of Schlafhorst, the Germany-based subsidiary of Saurer, to the ever more exacting demands of the market on machine flexibility and productivity. With its up to 360 spinning positions, its one, two, three or four Coromat units and take-up speeds up to 300 m/min, the Autocoro 360 is the longest and most productive rotor spinning machine offered to spinners in the world market. The machine can be fitted and supplied with a fancy yarn spinning system, named Fancynation. The integration of the hardware components ensures highest efficiency in the production of effect yarns. The software for designing and programming effect yarns on a Laptop, specifically developed for the Autocoro 360, ensures high process reliability, reproducibility and simple handling and operation. The new Corobox SE 12 spinbox implements a novel drive concept for the sliver intake, the SDSI Single Drive Sliver Intake. Higher economic efficiency is guaranteed by the new CoroPack yarn packages weighing up to 5 kg. The Autocoro 360 is equally suited for the production of coarse yarns and of fine yarns for weaving and knitting. It can spin yarns flexibly from a wide variety of raw materials. Optimum spinning results are guaranteed in spinning yarns from cotton, even of very irregular quality, and from manmade fibres - the global growth market of the future.
In the semi-automatic rotor spinning machine sector, the new types BD 330 and BD 350Fancynation have been added to the mill-proven types BD 320 and BD 321.

Highlights of the new machine types are the features: EVA Electronic Vacuum Adjustment for the electronic regulation of the spinning vacuum, Joint Spinning-in JSI for automatic start of spinning at the start of the machine, and the new sliver-intake control in the spinbox. In addition to these features, the BD 350 Fancynation has an integrated effect-yarn spinning system. All BD-type machines spin yarns with rotor speeds up to 100,000 rpm and yarn take-up speeds up to 170 m/min. With their high levels of productivity and reliability, all the machines of the BD series stand out clearly from manual and other semi-automatic rotor spinning machines.
