From the Sector

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:

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.

International technology Group ANDRITZ has received an order from Amarande SAS to supply an elliptical cylinder pre-needler for their plant in Lussac les Châteaux, France. This machine will process shoddy and natural fibers for the production of heavy felts. Installation and start-up of the machine are scheduled for the second quarter of 2021. The new needlepunch production line with the high-performance ANDRITZ cylinder pre-needler will allow Amarande to offer high-quality products and thus open up new market opportunities.

ANDRITZ offers a complete range of elliptical cylinder pre-needlers serving different weights, widths, speeds and punching capacity. Over the years they have become a must for production of heavy products, special applications and also for demanding applications like automotive. They are a key success factor in enabling the subsequent needling machines to process heavy batts smoothly and control the progressive draft through the consolidation process.  

Established in 1990, Amarande is an important French producer of nonwovens, specialized in the production of felt and wadding from recycled textile and natural fibers (wool, cotton, hemp, flax, jute, etc.). The company operates in various markets such as furniture, green spaces, horticultural crops, and insulation.

International technology Group ANDRITZ has received an order from Pureko Sp. z o.o. to supply a needlepunch line for their plant in Myszków, Poland. The line will process recycling fibers from garment waste for the production of technical felts dedicated to furniture and geotextile applications. The final products will have fabric weights ranging from 300 to 500 gsm, and the production capacity will be up to 750 kg/h. Installation and start-up are scheduled for the third quarter of 2021.

The ANDRITZ scope of supply includes a complete neXline needlepunch eXcelle line – from web forming to needling – as well as engineering and ANDRITZ’s recently launched scanning gauge.

This is the second ANDRITZ line to be supplied to Pureko, thus demonstrating the strong partnership between both companies. Three years ago, Pureko invested in a new, modern plant supplied by ANDRITZ Asselin-Thibeau to produce fluffy nonwovens used in the furniture, textile, and clothing industries. The new line will enable Pureko to continue its ongoing growth.

Founded in 2009, Pureko is one of the most important producers of nonwovens in Poland. The company’s nonwoven products are mainly used for wadding; they are free of chemicals, do not involve any health hazards, and are hypoallergenic. Pureko’s products carry top certificates such as INTERTEK, FIRA, OEKO-TEX, and the National Institute of Hygiene.
