Spinning: process control becomes a unique experience
Fiber quality measurement in spinning preparation is crucial for minimizing waste and meeting yarn quality specifications. Uster AFIS 6 stands out by uniquely testing man-made fiber properties in addition to cotton, delivering critical data for optimized process control — also for blended yarns. In the upcoming Uster webinar, experts demonstrate its ease of operation and data interpretation, and reveal how users can fully unlock its potential.
Spinners always strive to preserve the quality of valuable incoming fiber throughout the manufacturing process. Uster AFIS 6 achieves this by testing the material at each stage of preparation, from bale to roving. And, in its latest version, AFIS can now measure 100% synthetic fibers and fiber blends commonly used in short-staple spinning, in the same unit as cotton.
Process control – smart and easy
The new Uster webinar shows the possibilities going with the new application range, and introduces the improved ease of operation and data interpretation of the AFIS 6. The experts, Anja Schleth and Theresa Ritter, will also share first field experiences and real application examples.
The topics are tailored specifically to mill and quality managers, as well as to textile technologists responsible for applications and product development. The Uster webinar takes place on April 15, 2026, from 16:30 pm to 17:15 pm, IST.

Ongoing fiber quality monitoring
Several different fiber characteristics affect quality and performance through pre-spinning operations – opening, cleaning, carding, combing, roving – so testing needs to take account of the impact of each. AFIS (short for Advanced Fiber Information System) achieves this by measuring the various parameters for the length, fineness, maturity, neps, seed coat neps, trash, and dust in a particular test specimen of fiber.
This intensive monitoring is the only way to detect fiber quality issues before they get into the yarn and lead to a quality claim from the customer. Only industry-leading Uster AFIS 6 can deliver these advantages to give mills better overall control of costs, reduced raw material waste and less off-quality yarn.
AFIS 6 also makes things easier for the spinner, applying the same intuitive new user interface as the famous Uster Tester 6 and other Uster yarn testing instruments, featuring 11 languages. The improved reporting package simplifies data analysis.
Managing synthetics the same way
Synthetic fibers are growing in importance, so it’s essential to measure them. The cut length and fiber fineness are particularly relevant, as both are crucial for the spinning process. Uster AFIS 6 can measure the synthetic fibers most commonly used in short staple spinning. As well as length and fineness, fiber neps are determined. New test parameters are also introduced, such as cut length and denier. They are critical for incoming raw material inspection and selection.
Short-staple yarns today include more and more cotton/synthetic blends and 100% synthetics. Cotton can be blended with fibers such as polyester, micro-polyester, viscose, modal, micro-modal, lyocell, micro-lyocell, and acrylic.
Quality and profitability in control
Carding and combing are the two fiber processes in the spinning mill which most influence yarn quality. The carding process is the heart of every spinning mill. Poor performance here cannot be recovered in subsequent processes. The combing process reduces the short fiber content and is the last removal stage for neps, trash and dust. Only with Uster AFIS 6 measurements can spinners optimize these processes and save money.
Spinners have it in their own hands! The latest Uster fiber process control system puts them in control of spinning preparation – and the end-product’s success.
