Mill optimization through Quality Management Platform

18.09.2019 Improvements have once again been made in the Uster Tester 6 from the provider of textile testing and quality control solutions, Uster Technologies AG, Uster/Switzerland: the facility for measuring conductive yarn through the Frequent Occurrences (FO) feature, and the high-speed assessment of twist and twist variation as part of a single yarn testing routine.

Uster Tester 6 hosts Uster Quality Expert, the digital solution for integrated data-based improvements throughout the spinning mill, connecting and interpreting information from a range of different instruments in the Quality Management Platform. For the first time, spinners have access to all the possibilities for total mill optimization.
Until now it has not been possible to measure the quality of conductive yarns, which have become more important in the past decade in fast-growing markets such as protective wear, fitness clothing, and healthcare. Sensor OM is now used to measure FO in these yarns. It analyzes neps, thin and thick places, yarn evenness, diameter, density and shape.
The twist level in a yarn is a critical quality parameter that affects both the look and performance of the finished product, as well as the productivity level. Now, this important parameter can be measured as a simple by-product of yarn testing for 100% cotton ring and compact yarn – providing information about all relevant parameters as part of one laboratory procedure. Uster Tester 6 offers the option to obtain Twist and Twist variation (Tu) data during yarn testing, at a speed of 800 m/min. This information helps to identify performance gaps such as low-speed spindles.
Measurement data from Uster Tester 6 correlates perfectly with Uster Statistics global benchmarks. It is available in an app for iOS, Android and Windows 10, and the new version 1.4 is now available with an enlarged database of the most popular yarn styles, 100% cotton, compact yarns for knitting applications, extended FAQs and enhanced readability.
