DiloGroup at Techtextil with nonwovens technology

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

  1. Intense Needling
    Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
    Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
  2. “Fibre Pulp Recycling”
    Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
    When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
  3. Additive nonwoven production
    The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
  4. “IsoFeed”-card feeding
    In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

DiloGroup: successful INDEX exhibition

DiloGroup would like to thank all customers and interested parties for visiting the Dilo booth in Geneva. Despite the existing worldwide Covid, we were able to welcome a great number of well-known faces as well as meet new contacts, among them the most important nonwovens producers from across the world in all application areas: hygiene and lightweight nonwovens, technical textiles and needled nonwovens including geotextiles, filter media and automotive. The interest in using resource saving plant engineering, energy saving and the processing of natural fibres remains.

Dilo presented its latest developments in industry 4.0. Systematic plant monitoring and analysis of machine data allows simplified operation and more effective production. This smart system was illustrated with the aid of live analysis of the performance, quality and availability parameters of the production lines in our Textile Research Centre. The new production systems Hyperpunch Alpha, HyperTex and 3D-Lofter were explained with the aid of videos which led to a very positive responsive from the many different producers which are interested in running trials at the Dilo Textile Research Centre to further explore these subjects. These highlights and further new developments were the basis for fruitful technical discussions.

DiloGroup at Techtextil India

  • DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.
