Technical textiles, machines and components developed in Switzerland will be shown at the Members’ Pavillion of the Swiss Textile Machinery Association (Swissmem), Zurich/Switzerland, at the Techtextil, the international exhibition for technical textiles and nonwovens. 24 Swiss companies will exhibit either at the Swiss Association’s Member’s Pavilion or at individual stands at the event in Frankfurt/Germany from June 21-24, 2022.
Nonwovens are used in various technical textile products, including filtration, geotextiles, automotive, carpets, technical felts, wadding, insulation and hygiene applications and wipes. The best results start from the right conditions in the mill. Luwa Air Engineering AG, Uster/Switzerland, has developed a sustainable humidification system – a hygienic solution with high energy-efficiency since its technology is not based on steam. The company also offers unique filters for removal of airborne fibers and additives such as super absorbent powders.
Sustainable manufacturing is also a key goal for Autefa Solutions Switzerland AG, Frauenfeld/Switzerland, with a focus on manufacturing systems which preserve both energy and raw materials. Spunlace processes can require relatively high energy usage, but the company’s unique combination of hydroentanglement machine and drum dryer can reduce energy consumption by up to 30%. Customers can also modernize existing production lines. Product quality in needlepunching lines can be monitored and improved by a sophisticated control system. This results in very good uniformity in the fabric by managing weight distribution through accurate settings at the crosslapper and the card feed.
The innovative design of products such as metallic card clothing of Graf + Cie AG, Rapperswil/Switzerland, a subsidiary of Rieter AG, Winterthur/Switzerland, helps manufacturers consistently produce high quality webs. Thanks to its precise fiber transfer, 20% fewer failures are produced in the web. The superior performance increases throughput by up to 10% and results in greater carding efficiency. This applies to both short and long staple fibers bonded by chemical, mechanical, thermal or solvent treatments. The resultant webs hold the fabric together more durably.
Crealet AG, Wald/Switzerland, provides specialized electronic warp thread feed solutions. These highly reliable systems are applicable to various types of weaving machines, with customized solutions also offered. The company’s extensive know-how spans mechanical engineering, drive technology, electronics, software development and textile technology. Yarn tension is a major factor in warp feeding, and effective solutions have been devised which quickly and precisely synchronize the tension of different warp beams, and which connect to an integrated network.
Yarn and weft control systems by Loepfe Brothers Ltd., Wetzikon/Switzerland, detect the smallest filamentation, fluff and knots, as well as all types of weft faults, during the weaving process. They drive quality assurance to reach zero-defect manufacturing, meeting the high demands of technical textiles. Loepfe solutions are particularly well represented in the automotive industry in applications such as airbags, car glass, seats, carbon materials, and tire cords. Its optical yarn defect sensor provides all-around control over the entire running yarn.
The quality assurance system from Uster AG, Uster/Switzerland, uses automated control during intermediate and final inspection, removing the need for costly manual inspection. The system’s ability to capture any visible defects prevents claims. Uster optimized cut control is a software tool for automated cut optimization that can be installed on any existing de-batching or cutting line, allowing significantly higher yields.
