SLUB YARNS FOR FASHION FABRICS THE CHALLENGE

One of the biggest fashion trends in textiles today is for denim jeans with yarn slubs. For the latest high-fashion jeans brands, these slub effects are seen as an essential selling point. Their appeal lies in their apparent random distribution and irregular appearance throughout the yarn, giving the jeans a casual yet classy look.

Great for the style-conscious consumer, but not so easy for the spinner, who must meet the technical challenge of producing a yarn that looks natural and unsystematic – while in fact being manufactured to precise and consistently-controlled quality standards, along every meter of yarn, from sample to sample. Potential problems such as mass decreases after a slub, or unexpected patterning effects caused by incorrect machine settings, can make the whole process a nightmare for any yarn producer.

That is where USTER^® comes in, with the newly-developed Fancy Yarn Profile, used with the world-famous USTER^® TESTER 5 quality testing system. The Fancy Yarn Profile accurately and reliably analyses slub yarns, making it simpler than ever before to ensure the slub yarn manufacturing process is carried out with the required consistency and quality – without losing the all-important ‘irregular’ appearance in the finished fabric – for both ring and rotor yarns.

AND THE SOLUTION: THE NEW USTER^® FANCY YARN PROFILE

The USTER^® Fancy Yarn Profile has been developed specifically to solve the quality-with-irregularity headache in slub yarn production. It is available as a special option for the renowned USTER^® TESTER 5 evenness tester family, including both the high-speed and super-versatile model S800 and the S400, with its unique functionalities.

The flagship USTER^® TESTER 5-S800 tests all the most important quality parameters, such as yarn evenness and imperfections, with unrivaled precision and total reproducibility – and at an amazing speed of 800 m/min. Its combination of several sensor technologies means the S800 is able to cover every yarn quality assessment requirement, including foreign matter content, yarn hairiness, dust and trash content and yarn diameter and shape.

The USTER^® TESTER 5-S400 offers a precision testing solution for all the key quality parameters related to mass evenness and imperfections in yarns, with fully-reproducible and comparable results. Specially tailored to provide an attractive balance of functionality and price, it puts modern spinning plants in total control of their production quality.

SETTING A NEW STANDARD FOR SLUB YARNS

All the vital qualitative features of slub yarns – slub length, distance between slubs, and increases in mass – are accurately and quickly determined by the USTER^® Fancy Yarn Profile.

What’s more, this vital data is presented clearly and precisely in a series of graphic displays and reports, covering every detail of the slub yarn’s characteristics. Sample reports and charts are illustrated here. Users can quickly identify all the vital issues affecting how the yarn will look in the finished product, and take any action necessary to modify machine settings to engineer the required yarn properties.

MORE REPORT OPTIONS: BETTER AND EASIER ANALYSIS

The complex structure of fancy yarns calls for a more detailed approach to analyzing the quality characteristics of slub yarns. It is clear that one single report may not be enough to provide the full picture.

USTER^® has therefore extended the range of reports available with the USTER^® TESTER 5 to include a multitude of options for slub yarn analysis. Users can select from scatter plot, slub classification matrix, histogram, slub sequence diagrams, bar charts, spectrogram and impressive 3D displays – all of which make for easier and more accurate assessment of yarn characteristics.

The USTER^® Fancy Yarn Profile and the USTER^® TESTER 5 – the perfect partnership for effective measurement and analysis of slub yarns.
