Global demand for synthetic fibers is at an all-time high, with more than 80% capacity utilization and a production total of almost 50 million tonnes expected for 2011, following a strong recovery in 2010. Mass variation as well as strength and elongation are the essential quality characteristics for this big business. The USTER® TESTER 5-C800 and TENSORAPID 4-C are the indispensable and specialized testing instruments for filament yarn producers.
Reflecting the filament industry’s needs leads to the conclusion that two USTER® testing instruments offer what is necessary to ensure requested quality standards: The USTER® TESTER 5-C800 – part of the renowned USTER® tester family – is tailor-made for this industry and has become a synonym for unevenness measurements. The USTER® TENSORAPID 4-C measures the key quality parameters of force, elongation and tenacity, using software specially designed for filament yarns. Both systems can test a wide range of counts across all the main filament yarn types, including polyester, polyamide, polypropylene, viscose and aramid. Gabriela Peters, Product Manager Yarn within Uster Technologies says: “Our long expertise in this area means we understand that the testing of monofilament or multifilament is not as simple as it looks.” In fact, it can be a complex process, requiring the specialized know-how, hardware and software that is integrated into the USTER® instruments. “We work with filament producers to keep pace with fast-moving changes in manufacturing technology and new demands on yarn characteristics as competition intensifies through the textile sector, including high-volume applications such as polyester for apparel, sport textiles and home textiles,” explains Peters.
