Times of crisis are challenging, but also reveal opportunities. At the 2 upcoming trade fairs, the ITM 2022 in Istanbul/Turkey and the Techtextil in Frankfurt/Germany, interested customers can personally get an idea of Brückner's new developments. This includes e.g. the new Opti-Coat 2-in-1 coating unit which combines the advantages of application via floating knife and knife-over-cylinder in one system. Due to its design, the unit offers good accessibility for maintenance and cleaning work and delivers very good coating results.
The newly developed stenter concept with double heating system from Brückner Textile Technologies GmbH & Co. KG, Leonberg/Germany, can be operated with gas or oil, depending on availability, but other combinations with steam or renewable energies are also possible. In addition, the company has developed intelligent assistance systems for its machines to operate the line as energy-efficiently as possible. This also helps to avoid harmful emissions.
For reducing chemicals, the Eco-Coat minimum application unit can make a decisive contribution. Knitted and woven fabrics, as well as nonwovens can be finished on one or both sides using different fabric paths. With the minimum application through an engraved roller, a single-sided application of up to 100 g/m² can be achieved. A double-sided and higher application quantity is achieved, for example, by impregnation in the nip. Irrespective of the selected fabric path, a very small liquor reservoir means that only minimal quantities of wastewater are produced when changing batches or liquors, and the use of chemicals can also be significantly reduced. In addition, less water is evaporated in the subsequent drying process, meaning energy requirement is significantly reduced.
