Mesdan cotton stickiness testing method recognition

If “sticky cotton” is not detected in time and properly handled, it can generate excessive maintenance costs in spinning, affect the production and compromise yarn quality. There are several testing techniques for determining cotton stickiness: chemical, mechanical and thermo-mechanical methods.

In the latest findings of the ITMF International Committee on Cotton Testing Methods, in cooperation with CIRAD, Fiber Institute Bremen and ICA Bremen, one important conclusion has been outlined:

due to its highest correlation with processing behaviour and yarn quality, only thermo-mechanical methods are recommended (in both production and trade).

In fact, the high variation in stickiness within a sample, as well as within a bale and within a lot, makes the thermo-mechanical method suitably designed for daily massive testing, in a trading context as well as in the spinning mill, thus overcoming the constraints of other methods (chemical and physical).

Among different thermo-mechanical equipment used in the ITMF-ICCTM proficiency testing, the CONTEST-S results were proven to provide the lowest inter laboratory CV% variations.

In order to supply a solution to overcome the troublesome effects of cotton stickiness (honeydew/sugar content), Mesdan developed a specific testing method as an integral part of its CONTEST-S and CONTEST-F equipment.

The STICKINESS module is distinguished by:

fully automatic high-volume testing equipment designed to detect, measure and classify cotton stickiness,

its unique feature of simulating the carding process like in real spinning conditions provides a reliable evaluation of the effective stickiness (cotton fibres tendency to stick to cotton-processing surfaces),

stickiness grade and cotton stickiness risk probability assessment enables spinners to anticipate proper actions (how to process & blend different cotton bales),

fast testing (30 sec/sample) designed for massive stickiness classification of bales and lots (>500 tests/shift),

testing method for stickiness grading recognised by ITMF - ICCTM.

Mesdan is proud to announce that its Stickiness testing method has recently received an official and full recognition by the ITMF International Committee on Cotton Testing Methods (ICCTM) in April 2020. The ITMF-ICCTM committee members recognised its usefulness and its benefits for the complete cotton supply chain: it assists spinners to achieve consistent yarn quality standards, it sustains traders and cotton suppliers to monitor season crop, it provides grading for research laboratories and classification institutes.

The complete document with all inter-laboratory evaluation details is available at the ITMF web site and can be downloaded at the following link:

The recognised testing method complies with the international standard EN 14278.

ITMA Asia 2026: How Barmag is reshaping the future of man-made fiber production

The textile industry is entering a groundbreaking era. Manufacturers face rising energy prices, growing sustainability demands, increasing labor shortages, and an unprecedented need for flexibility. For a globally active textile industry, where competitiveness is closely linked to production efficiency and cost leadership, this means that technology is no longer merely a means of improving operational processes – it is increasingly becoming a strategic differentiator.

Heberlein reinforces its commitment to the Chinese market

Heberlein, globally recognised as a leading provider of air interlacing and air texturing jets for synthetic filament yarns, is consolidating its success in the Chinese market with its APh- and APe-series for DTY applications. Particularly in the field of Air Covering, Heberlein technologies combine excellent quality with significant savings in compressed-air consumption. A new service hub in Shengze City underlines the company’s long-term commitment in the Chinese market.

Driving circularity with Uster Recycled Fiber Matrix

The textile industry’s commitment to circularity continues to accelerate, and mechanical recycling is viewed as a targeted approach to cutting textile waste and its environmental impact. At the forefront of this drive, Uster has developed the Recycled Fiber Matrix, a two-dimensional assessment of mechanically recycled fibers to guide optimum processing and end-uses.

Coats Digital launches AI-powered GSD RealMotion for motion analysis

Coats Digital has launched GSD RealMotion, an AI-powered solution designed to provide apparel manufacturers with greater visibility into factory-floor operations. By analysing shop-floor video and applying Coats Digital’s GSD methodology, the solution turns video recordings into structured, motion-by-motion method studies.

Archroma and Lameirinho partner in pioneering deployment of InOneGO single-step dyeing

Archroma, a global leader in specialty chemicals, and Lameirinho, a leading home textiles manufacturer based in Portugal, are collaborating to bring InOneGO by Archroma, a new single-step dyeing process, into commercial production. Lameirinho’s first InOneGo bedlinens collection is now available worldwide.

Reducing development times for technical textiles by accelerated thermo-oxidative aging in a high-pressure autoclave

Synthetic polymers used in technical textiles can be effectively protected against degradation caused by heat, oxygen, and water through the use of stabilizer systems. This enables service lives of several decades, extending to more than 50 years. As the use of durable technical textiles continues to grow, so does the demand for reliable methods to predict their service life within economically feasible testing periods. For the first time the German Institutes of Textile and Fiber Research Denkendorf (DITF) developed methods for robust service life prediction for textiles in an IGF research project.
