Nonwovens: When Quality is Super - Critical…

USTER® fibre cleaning systems prevent contamination in hygiene and cosmetic applications.

Yarn spinners already understand the importance of preventing contamination in their products. A total of 3,500 worldwide installations of Jossi fibre cleaning systems – now produced by USTER – is proof of that. The USTER® JOSSI VISION SHIELD solutions are highly effective at removing even the smallest contaminants, including polypropylene. For nonwovens producers, however, the risk of contamination is possibly even greater: in medical and hygiene applications, for example, quality standards are super-critical and zero contamination is essential.

Contaminated yarn is one of the spinner’s biggest headaches, potentially leading to customer claims and rejects when synthetic particles such as polypropylene (PP) remain undetected in cotton until the fabric reaches the dye house. Today, the range of USTER® JOSSI systems is proven to deal with this problem with unbeatable effectiveness, detecting and removing foreign matter from cotton at the spinning preparation stage.

Uster acquired Jossi AG in 2013 and now applies the USTER® JOSSI VISION SHIELD 2 and USTER® JOSSI VISION SHIELD T systems, using multiple detection principles to eject all polypropylene particles, however minute. The finest white PP contamination is reliably and efficiently detected with the USTER® JOSSI MAGIC EYE in combination with the USTER® JOSSI VISION SHIELD. Practically all types of foreign matter, including polypropylene and polyethylene, are eliminated by USTER® JOSSI MAGIC EYE, with a minimum of waste.
