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:

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.

ChemSec' Study: Consumer brands demand clarity on recycled plastics

A new interview study from NGO ChemSec shows that there is a gap between supply and demand when it comes to recycled materials, causing confusion and bottlenecks. Among other things, suppliers go out of their way using elaborate trade schemes to reach the coveted ”100% recycled” tag, which – it turns out – is not that important to consumer product brands. Far more crucial aspects, according to several major B2C companies, are:

  • Honest communication towards customers
  • Comprehensive information from suppliers
  • Clear standards for recycled material

These are some of the conclusions from NGO ChemSec’s survey and interview study with 26 highly well-known consumer product brands. All brands responded to a survey concerning their current plastic use, as well as their needs, expectations and challenges regarding using more recycled material, to enable the shift to a circular economy for plastics.

Ten of the brands then participated in in-depth interviews on the same topics:, Essity, H&M, IKEA, Inditex , Lego, Mars,  SC Johnson, Tarkett, Unilever and Walgreens Boots Alliance.

Is non-mechanical recycling the answer?
Only about ten percent of all discarded plastics is recycled today, which is of course not nearly enough to achieve a circular plastics economy. Despite ambitions and initiatives to reduce plastics use – replacing the materials with other, more sustainable ones – the “plastic tap” is not expected to be turned off anytime soon. Quite the opposite, which makes raising the recycling rates more important than ever.

Although commercially viable, traditional (mechanical) recycling is afflicted with severe flaws, such as legacy chemicals, quality and functionality issues, as well as the lack of clean and sorted waste streams. The brands cited quality and functionality issues as the main obstacles for using more recycled material in their products.

This opens up for non-mechanical recycling, sometimes referred to as chemical recycling, where the plastic is either dissolved or broken down into smaller building blocks. Harmful additives and other hazardous chemicals can be removed in the process, and a material comparable to virgin plastic can be achieved – at least in theory.

So far, however, non-mechanical recycling technologies are costly, energy-intensive, and often require the addition of a great deal of virgin plastic to work – the very material that needs to be phased out.

The chain of custody models needs to be detangled
Apart from these production issues, there is a wide range of chain of custody models surrounding non-mechanical recycling, including mass balance and book & claim, which enable trade of credits or certificates for recycled material.

This cuts the physical connection between input and output, making it possible for a supplier to sell a material as “100% recycled”, when the actual recycled content could be zero.

This is a major issue for the brands ChemSec has spoken to, who value honest and correct communication towards customers. It turns out, perhaps somewhat surprisingly, that being able to slap a “made from 100% recycled plastic” label on a product is not all that important to brands.

To the brands, a physical connection between input (the discarded plastic waste headed for recycling) and output (the product at least partially made from recycled plastics) is far more important.

A physical connection, along with correct and adequate information from suppliers, as well as clearer standards and guidelines than what is available today, is what brands require to increase the use of recycled material and move us closer to a circular economy for plastics.
