First Hand from Second Hand: New Clothes from Old

04.12.2009
Dutch and German project partners, including the Laser Zentrum Hannover (LZH), are working on a production chain which will turn old clothes into new clothes.

The "heart" of the sorting line is a spectroscopy system developed by the LZH. Based on the reflection spectrum of each material in the visible and infrared range, the system will recognize not only which material it is (cotton, wool, polyester), but also the color.

Used clothes are collected in all major European countries, but what really happens to these textiles? About half are wearable and find their way back into consumer textiles. The other half are either recycled for industrial purposed, for example as insulation material, or they are disposed of. A new European project plans on offering an alternative: Making new clothes from old clothes.

Dutch and German project partners, including the Laser Zentrum Hannover (LZH), are working on a production chain which will turn old clothes into new clothes. The first step is sorting. First wearable clothes are sorted out manually. The rest are automatically sorted according to material and color. The more "pure" in material and color the batches are, the better they can be further processed. The goal of material identification is to reach a 95-99% sorting accuracy at a speed of at least 10 kilograms per minute.

The "heart" of the sorting line is a spectroscopy system developed by the LZH. Based on the reflection spectrum of each material in the visible and infrared range, the system will recognize not only which material it is (cotton, wool, polyester), but also the color. The LZH is responsible for the conception of the identity unit and the software development.

After identification and sorting, the textiles shredded and spun into new threads, which are then woven into new textiles and eventually made into new clothes.

Commercialization of the technology should lead to at least 10 sorting plants in Europe. The 30 month project is supported by the Eco-Innovation Program of the European Commission.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
