Growing demand for weft yarn quality control

on air-jet weaving machines

When processing filament yarns on air-jet weaving machines, up to 90% of machine downtimes can be attributed to weft faults. Weft faults arise largely due to production-related defects and irregularities in the yarn.

In the weaving process of technical fabrics made from multifilaments, filamentation, individual fibril breaks, fluff or the smallest knots in the weft yarn are a problem. The perfect fabric appearance is thereby disturbed, especially with fabrics for ambient lighting, sun and light protection, coating carriers, filtration, precision fabrics and architecture fabrics.

The consequences of undetected flaws in the weft yarn are defective fabrics and expensive complaints. For reliable monitoring and efficient defect detection, the Falcon-i yarn defect sensor is mounted in front of the weft feeder.

The aim with the use of the optical yarn defect sensor FALCON-i is to increase the fabric quality by reducing the number of fabric defects caused by defective weft yarn.

The Falcon-i sensor also offers reliable quality monitoring for manufacturers of knitted fabrics for technical and smart textiles.
