Uster Technologies, in its industry often called Uster, is a Swiss manufacturer of analytical instruments and on-line monitoring systems for the textile industry, based in Uster, Switzerland. It emerged as a management buy-out form of the Zellweger Luwa Group in 2003. From 2007 until 2012 the company was publicly traded and listed on the main segment of SIX Swiss Exchange. Since 2012 Uster Technologies is a subsidiary of Toyota Industries Corporation.
Uster Technologies mainly produces laboratory and on-line systems used to measure and control the quality of fibers and yarns.
Modern, industrial cotton gins often operate with sensors by Uster, to control their process and to the resulting fiber quality.
Cotton classing is required to measure and classify each cotton bale according to its specific physical attributes. Measurement information produced by Uster's HVI (High Volume Instrument) covers following parameters: fiber length, length uniformity, fiber strength, fiber maturity, short fiber content, micronaire (fiber fineness), color grade, leaf and extraneous matter.
When cotton is traded, its value is determined by the above-mentioned quality parameters, as measured by the HVI in the classing agencies. Hence Uster's HVI has defined a set of standards for a large part of all cotton trades worldwide.
Uster products are used in the spinning mill for measuring and analyzing the quality of the raw materials (i.e., fibers of different materials), intermediate products (i.e., sliver, roving) and final product (i.e., yarn) along their entire manufacturing process.
Most important process parameters a spinning mill has to control are: quality of the incoming fibers, yarn evenness, hairiness, tensile strength and elongation, contamination with disturbing materials, twist, friction, etc. By measuring these parameters, the instruments can be used as tools for a mill-wide quality assurance process.
