From the Sector

Partnership between Nouvelles Fibres Textiles, Pellenc ST and ANDRITZ promotes circular economy for textiles.

France’s first industrial plant for automated sorting and recycling of textile waste was officially inaugurated at Nouvelles Fibres Textiles, Amplepuis, on November 30, 2023. The plant is the result of an ambitious partnership between textile recycling company Nouvelles Fibres Textiles, waste sorting specialist Pellenc ST and international technology group ANDRITZ, a specialist in textile recycling machinery and processes.

Capable of automatically sorting garments by composition and color, the new line meets the needs of both post-consumer and post-industrial waste markets. The line also removes hard parts such as buttons and zippers to prepare the material for further processing in an ANDRITZ tearing machine.

The automated textile sorting line at Nouvelles Fibres Textiles is dedicated to industrial-scale production, customer trials and projects, and the R&D activities of the partners. It will process textile waste to produce recycled fibers for the spinning, nonwovens, and composites industries.

Automated sorting was the last missing link needed to develop a complete ecosystem in France, where the fashion industry, social and solidarity economy actors, waste management companies, and textile producers from different sectors are working together towards a textile circular economy.

The EU's strategy for sustainable and circular textiles aims to ensure that by 2030 textile products are made to a great extent of recycled fibers and incineration and landfilling of textiles are minimized.

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.
