Lenzing Lyocell considers industrial prospects for solvent-spun fibre

At the official opening of Lenzing Lyocell GmbH and Co. KG's fibre production facility in Heiligenkreuz, Austria, AG, Dr Heinrich Stepniczka (the Director General of the parent group Lenzing) confirmed the innovative technical applications for Lyocell that are beginning to be evaluated. The company will concentrate its marketing efforts o..

The flock industry - past, present and future

The flocking industry has experienced tremendous growth over the past three decades. A larger number of applications are now available which leads to more opportunities to produce a wide variety of a flocked products. This is due to the technological adva

Yarn Twist Blockage.

An analytical model describes the relationship between twist blockage and yarn. Yarn tension and the wrapping angle over the yarn guide affect twist blockage. Because oscilations in yarn tension and wrapping angle occur simultaneously, the yarn twist reproduces itself through the guide in surges, which may cause large variances in twist a..

Prehistory and History of the Devlopment of the Autocoro

A history of the development of Schlafhorst's Autocoro open end rotor spinning machines begins in 1807, when the first patent was submitted for this technology in Great Britain. Implementation of this concept, however, did not occur until 1965, when the first generation was introduced. Schlafhorst was not involved in the manufacture of th..

Optimizing Material Flow for the Autocoro Spinning Plant.

Neuenhauser Maschinenbau Gmbh ＆ Company and Schlafhorst developed the Autoflow system, an automated package removal system, to optimize processing at the Autocoro spinning plant between manufacture and delivery. Advantages of the Autoflow system include continuous package removal, reduced removal time regardless of the number of packages..

Cost-Saving in Speed Frame.

The Zinser Ro-We-Mat 670 yarn spinning machine reduces costs by streamlining processing stages via a new drive and control concept. Tubes on the spindles running on bearings in the bobbin rail move without a corresponding motion at the bottom or top support elements, which eliminates friction and wear. A spinning geometry that includes th..

Structural Analysis of Blended Sliver Composed of Long and Short Fibers.

A study measured the fiber leading end density of blended sliver composed of long and short fibers and obtained cross sectional numbers using a sliver diagram. Researchers analyzed the sliver structure along the sliver axis and examined the influence of various drafting conditions on the sliver structure. In all regions along the sliver a..

Spinning Quality/Process Improvement through Variance Tolerancing.

Future control and improvement of textile process qualities will develop from a proper analysis of the variance on input and output variables combined with valid structural relatonships. To develop a strategy for predicting the tensile strengths of spun y

Ramie-Silk Blends.

A study blended ramie fibers with various forms of silk waste in the carding stage and quantified the physical properties of the resultant yarns. The highest yarn count (12) resulted from a 50/50 ramie/mulberry blend. As the percentage of ramie fibers in

Spinnability of Aramid Fibres.

Researchers investigating the manufacture of yarns from aramid staple fibers developed technology for the manufacture of 27-28 tex yarns from Oksalon and Terlo aramid fibers and their blends, as well as for the manufacture of 125 tex yarns from recycled Kevalr fibers. Results indicated that the spinning of aramid staple fibers should incl..
