New protective treatment for light-coloured furnishing fabrics

27.01.2010
Nanosol coating protects against colour transfer from darker textiles
Furniture with light-coloured upholstery is very fashionable just now, but it gives rise to numerous complaints to retailers and manufacturers on account of discoloration caused by other textiles.

Traditional stain-repellent treatments, usually based on fluorocarbon resins, are not the answer here: while they may offer effective protection from standard water- or oil-based stains such as food and drink, they cannot prevent colour transfer caused by (excess) dye in clothing or other domestic textiles.

That is why, at the Hohenstein Clothing Physiology Institute (BPI), in partnership with the German Textile Research Centre North-West, and as part of a research project (IGF no. 15151 N), they have been looking for ways of preventing light-coloured furnishing fabrics from becoming discoloured by textiles where the colourfastness is poor when rubbed. The scientists tested to what extent an anti-adhesive, quasi-ceramic, nanosol-based coating could prevent the discoloration or at least make it easier to remove with normal cleaning methods.

As part of the project, all kinds of different nanosols were synthesised and applied to a range of furnishing fabrics. Then the textile and performance-related characteristics of materials treated in this way were analysed in detail. The results obtained show that the colour transfer is primarily caused by dye abrasion and not, as was originally thought, by abrasion of coloured fibres. It also became clear that discoloration of light furnishing fabrics could not be entirely prevented even with this approach. However, some of the synthesised treatments tested in the research project do allow the dye to be completely cleaned off by using a microfibre cloth soaked in washing solvent.

More research work will be required before the process is ready to be brought to market, because the treatments tested so far cannot yet combine complete removal of the dye with water- and oil-repellent qualities. Nevertheless, combining a number of new developments resulting from the research project may make it possible to synthesise a hydro- and oleophobic treatment which has excellent dye removing properties in the future.

We are grateful for the sponsorship for this project from the Textile Research Council, as part of the programme to support "Industrial Community Research" (IGF), with funds from the Federal Ministry of Economics and Technology (BMWi) provided through the Federation of Industrial Research Associations (AIF).

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
