At the Techtextil A. Monforts Textilmaschinen GmbH & Co. KG, Mönchengladbach/Germany, demonstrated a number of enhancements that have recently been made to its texCoat and Allround coating units.
In a major development for the coating of technical textiles and nonwovens, the company is now offering the coating roller for its texCoat and Allround coating units as an optional carbon fiber version, in order to meet even the highest level of coating accuracy that is being demanded.
The carbon rollers provide the extreme stiffness necessary to deal with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics, but at the same time, a significant improvement in coating accuracy is achieved, even for very lightweight flexible materials. In addition, the surfaces of the rollers are protected against both abrasion and damage from aggressive chemicals by a special ceramic coating.
A further benefit is that the rollers are much easier to clean.
Machine layouts for the technical textiles and nonwovens industries now account for more than 25% of Monforts’ turnover and notable recent successes have included the supply of a complete 6 m wide coating unit to a leading manufacturer of substrates for digitally-printed soft signage in Germany.
Other systems are in place for applications ranging from carbon fabrics for high-performance composites and filter media which must perform in extreme temperatures, to flame retardant barrier fabrics, heavy duty membranes for the collection and storage of methane in biogas plants, and materials equipped with sensors and electrical conductors employed as base liners in DSC solar cells etc.
All of these materials, however, have one thing in common – they all require expert coating and finishing for maximum efficiency and the technology to allow for ultimate flexibility and the ability to switch quickly from one fabric formula to the next, without compromising on the economical use of energy or raw materials.
Monforts is able to offer completely integrated coating lines from a single source and the coating machine is tailored to the subsequent drying technology – with all the benefits resulting from a fully integrated plc control. The systems have a very short fabric path from the coating unit into the stenter and the company has all variations of coating application systems too – and all of these options are available in wider widths.
