In the forthcoming Techtextil in Frankfurt from June 21-24 2022, Swiss Textile Machinery companies will highlight the benefits of using high-performance yarns in a wide range of technical applications.
Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ to find new applications in sectors such as automotive, aviation, maritime, medical and construction, among many others. For example, Heberlein’s air splicers are used to splice aramid fibres of up to 16,100 dtex, carbon up to 30,000 dtex, Dyneema up to 5,500 dtex, and glass up to 4,800 dtex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of the material without knots.
Retech has the technology to achieve impressive specifications for filament yarns by drawing and stretching fibres. It develops top heated godet rolls for high-performance fibres and temperatures up to 400°C.
Many of the technical yarns hidden inside today’s cars have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour arises from the choice of textile material and the special construction of the yarns used.
Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers ideal machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are employed in vehicle products such as tyre carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.
Technical yarns also play a surprising role in phones and other mobile devices. The touch-sensitivity taken for granted on their screens is largely made possible by twisted glass fibres. Bräcker, part of Rieter’s components business, offers a well-balanced selection of vertical sinter metal rings and nylon travellers for glass fibre twisting, so that mills can achieve the highest levels of productivity and quality.
