Uster Technologies, a high-technology instrument manufacturer of products for quality measurement and certification for the textile industry, has announced that its machinery for total cotton contamination control have proved to be successful at China’s Texhong Group. Texhong Group is engaged in the production of quality yarn, fabrics, and cotton.
Texhong has five fully-equipped Uster laboratories for fibre and yarn testing. The equipment includes Uster HVI1000 and Uster AFIS PRO 2 for fibre tests, Uster Tester 5 and 6, Uster Tensorapid 4 and Tensojet 4 for yarn tests, and Uster Classimat 5 for yarn classification.
Uster’s solution is based on the concept of stopping contamination at two vital stages of production – in the blowroom and at winding – using a coordinated approach. This is total contamination control, enabling the spinner to balance precise quality standards against process efficiency in a unique ‘dual control’ method, which guarantees satisfaction for both spinner and customer, using world-leading Uster technologies.
The first control point is at the preparation stage, as the Uster Jossi Vision Shield removes foreign matter after the fine cleaner in the blowroom. The second control point comes at the end of the production process, as Uster Quantum 3 yarn clearers check the yarn during winding. At this point, the clearing settings can be adjusted to give exactly the required tolerance of defect levels, matched to the mill’s productivity targets.
These two control systems, acting in tandem, have the technological sophistication to identify all types of foreign matter defects in raw cotton and yarn, whether the contamination is natural or synthetic material. Even white polypropylene (PP) is detected by the Uster Jossi Vision Shield and Uster Quantum 3. Together, these systems assure a maximum efficient way to eliminate all contamination.
