Environmental news and technical  innovation in the nonwovens sector

BARCELONA - Technology group Dilo hailed its demonstration at the recent ITMA exhibition a success with the final figures showing that more than 6,000 interested parties and customers from more than 80 countries visited the booth, which, with a space of 1150 m², was the largest booth in the nonwovens machinery sector.

With a focus on complete production lines for the nonwovens industry, Dilo said it was keen to show its complete systems capability while also demonstrating its ability to adapt to development work for specific customer requirements; the ultimate aim being to include these innovations in the company's standard portfolio where required.

In fibre preparation, for example, the components for opening and blending from DiloTemafa attracted great interest. The highlights of the upgraded bale opener Baltromix Pro series were illustrated by several new features designed with 'industry 4.0' in mind. Components include the Bale Timer, cleaning control, better accessibility for maintenance and the DI-LOWATT system for energy savings in fibre transport. The proven carding willow for further opening and pre-blending was equipped with modified workers and separate drives to create the prerequisites for fine opening.

A further speciality on show was the fine opening stage installed over the material box of the new FRS-P card feeder where a high dosing accuracy is achieved in cross and longitudinal directions. Also noteworthy was a very even flock mat and consequently, the high web quality at the VectorQuadroCard exit was a result of the high quality of synchronized fibre opening and web forming components.

The revised HyperLayer NT for the presentation of the latest high-speed precision layering technique also demonstrated new standards, which play an important role, particularly in hydroentanglement lines.

In this application, notes Dilo, it is important to achieve layering speeds of up to 190 m/minute using sophisticated viscose fibres and a layering width of about 4 m while at the same time showing high layering precision in a cross and longitudinal direction.

Elsewhere, the FutureLine study 3D-Lofter demonstrated how individual web forming units can deposit fibre masses on freely programmable spots in a longitudinal and cross direction thereby saving overall fibre mass in applications such as deep moulded parts for automotive interiors. This capability is said to reduce costs in production and operation.

This technology also has applications in more even flock mats for direct cards, while the aerodynamic web-forming concept known as IsoFeed is also an option along with the structuring of flat needlefelt floor coverings, which may be further processed with the DI-LOUR and DI-LOOP technology.

Dilo was also promoting the high stitch distribution uniformity achieved by the new needle pattern 6000 X in conjunction with the new Hyperpunch kinematics Hα which is able to reduce investment costs for numerous needlefelt production lines while also increasing surface quality.

During the exhibition, visitors also took the opportunity to discover examples of 'smart industry' concepts across the Dilo exhibit which using various software, the internet and the cloud, offer increased levels of transparency as well as control of the production process and the operating conditions.
