Uster Technologies, a leader in textile testing and quality control from Switzerland, is set to present its latest Uster Tester 6-C800 for filament yarn with production optimisation and quality assurance benefits, at Techtextil 2017, global expo for technical textiles and nonwovens, in Frankfurt, Germany, from May 9 to 12, 2017, in hall 6.1, booth B65.

The Uster Tester 6-C800 provides fast, accurate testing to the tightest tolerances, protecting filament producers against customer complaints and claims.

Raw materials for technical textiles cover a wide range of end-uses and performance requirements. Viscose fibres, for instance, are found in lightweight blouses as well as in wire cording and high-speed car tires. Polyester, common in low-price clothing, is also transformed in special high-tech versions, for sophisticated sportswear and outdoor clothing. Countless other examples of technical applications for filament yarns span sectors such as medical, industrial, transport, engineering, and protective clothing.

Despite this variety of products, there is one fundamental requirement which is common to all: the absolute need for yarn evenness, measured to close tolerances, to ensure that the functional and aesthetic properties of the finished article achieve the high quality standards that customers demand.

Evenness testing has to combine reliability, accuracy and speed. The Uster Tester 6-C800 is specially designed for filament yarn testing, to meet these criteria perfectly. At its heart is the new capacitive sensor, providing more accurate and reliable test results than ever before.

Typically, filament yarns show a CVm value around 1, so that even small deviations in evenness are likely to cause noticeable defects in the fabric. The increasing complexity of applications and performance standards – with fabrics needing to protect against water, wind, cold, heat, and even bullets – means that evenness is an absolute requirement.

The Uster Tester 6-C800 combines reliability with top speed operation. All models operate at the test speed of 800 m/min. Running on the automatic setting, the high sample throughput rate gives even better detection of quality exceptions. The result is lower labour costs and improved control of quality for the business.

The Uster Tester 6-C800 offers three new unique features to help yarn producers increase efficiency and improve quality. The measurement of interminglings is an innovation saving time and preventing variations in subsequent fabric appearance. An automatic twist scan facility has been developed, assist filament quality monitoring by making twister settings easier. The Knowledge Based System (KBS) quickly traces the cause of a quality problem on the spinning machine, with no need for extra settings or input from the machine supplier, via a single click on the spectrogram display.

The sophisticated sensor technology in the Uster Tester 6-C800 is rooted in continuous R&D aimed at higher performance and extended applications – echoing progress in the technical textiles yarns themselves. The new capacitive sensor empowers filament yarn producers with the expertise to deliver right-first-time quality. (GK)
