Constant control of yarn tension

Modern sensor technology and data processing systems can be used to control all the important processing parameters and also to implement a wide range of optimisation measures. The production sequences can be optimised, as well as entire value-added chains. The efficient monitoring of yarn tension and feed during warp preparation can increase weaving efficiency by up to 5 %.

The new MULTIGUARD yarn monitor gives advance warning of a yarn breakage

The new MULTIGUARD stop motion from KARL MAYER can make an important contribution here. This innovative system gives a warning in the event of yarn breakages or tension peaks, and generates parameters that can be used for internal production data management as well as external quality assurances within the framework of a quality management system.

All the yarn tension levels at a glance

MULTIGUARD continuously determines the tension values of each individual yarn at the exit of the creel and transmits the data to a computer for comparison with the target values. This generates a clear status report. The coloured indicators show the customer immediately which creel position lies within the tolerance, warning or stop ranges. This enables him to intervene quickly in the warping process if there are any deviations from the target values. The specific, measured tension values are displayed in a compact diagram. They can be used for internal analyses and for quality management of the warping process. KARL MAYER has also developed the PROACTIVE-Warping three-level, modular recording system, whereby each level contains more information. Module 1 manages all the basic data supplied by sensors on the warping machine relating to the warping or beaming quality.

For example, the data relates to the exact positioning of the bands in relation to the drum axis. Level 2 complements these values with optical analyses from an integrated camera on the machine, whereby the focus is on the width, position and parallel arrangement of the bands. In module 3, the data is also transferred to the quality record from the creel monitoring system, i.e. the individual yarn tension values from the MULTIGUARD system.

A good start on the market

MULTIGUARD was launched as a prototype for the first time at ITMA 2019, and this innovative system generated a huge level of interest. “The possibility of detecting critical deviations in yarn tension levels early on, and to intervene in order to adjust them was well received by our customers,” says Martin Fuhr, the Head of Development in KARL MAYER’s Warp Preparation Business Unit. A Belgian customer has already ordered the new yarn monitoring system. Further promising projects are currently being negotiated. MULTIGUARD is suitable for every type of creel. It is integrated into the machine’s software and monitor on new machines.

RDJ 6/2 in E 32: Finesse in Motion

The appearance of sports and casual shoes is as diverse as their applications, ranging from sporty to stylish and from functional to fashionably practical. In particular, spacer fabrics produced on highly flexible KARL MAYER double needle bar raschel machines with Jacquard technology are in high demand for manufacturing these trendy shoes. These efficient production machines enable attractive designs with integrated multifunctional zones on one or both fabric surfaces, such as breathable mesh structures. Flexible in size and positioning, these features enhance both aesthetics and wearing comfort.

3D designs with a wow factor made on HKS 4-M EL ECO: When crepe, ruffles, and sheer fabrics redefine fashion

Seersucker, flip-flap items, Fırfır, or crepe materials: structured fabrics have long been more than just a passing trend. They lend timeless looks depth, dynamism, and an exciting tactile dimension. Whether classic striped patterns or modern solid-color interpretations, these versatile pieces pair perfectly with casual and business-casual outfits and effortlessly create a modern look.

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.

ITA has developed a washable digital smart jacket with real-time feedback and an AI-powered app for rehabilitation

As part of the PhysioTaix research project, the Institut für Textiltechnik (ITA) of RWTH Aachen University is developing a digital smart jacket with integrated sensors. The jacket is washable and reusable; it tracks movements during rehabilitation exercises in real time and transmits the data to an app.
