Long-Lasting Perfume

30.12.2003


Researchers of the Moscow State Textile University have invented the way to impart a stable fragrance to fabrics and polymeric fibers. The smell of rose, hyacinth or lily of the valley does not disappear even after washing.



The application of aromatic rugs, polymeric fiber napkins or fragrant fabrics will be driven by fantasy that can be put to life thanks to the development by the Moscow scientists from the State Textile University. They have learned to process fabrics with special substances, which bind molecules of fragrant spirit provided that molecules of water are available in the air. As a result, the perfume becomes stable and it will even intensify after washing the fabric.

The chemists received miraculous compounds as a result of interaction of organosilicon substances with fragrant spirits, each of them possessing the scent to be imparted to fabric. The researchers applied fragrant spirits with the smell of rose, hyacinth and lily of the valley, mixed them with organosilicon substances and acquired viscous fluids, which gradually hardened upon heating. Such compounds are able to liberate fragrant spirits under the influence of water which is always contained in the air. Molecules of fragrant spirits evolve into the air and create the perfume.


To acquire a fabric with stable fragrance, the researchers applied a 1 percent aqueous emulsion of synthesized substances or their solution in organic solvents to refined fibers. The processed fibers were dried up at the room temperature, and then kept for 10 minutes at the temperature of 140 degrees C. In such a way, a fabric can be produced which will pleasantly smell, for example, of rose for nine months and will stand 20 washings every two weeks without losing the fragrance.

The processing by new compounds will not only impart pleasant scent, but will also increase durability of nonwoven fabrics made of polymeric fibers, which are used to produce, for example, clothes, various coverings, durable ropes and other useful things. Polyethylene turned out to be the ‘champion’ among the three tested polymeric fibers. Its durability increased by 13.2 times. For comparison, polypropylene increased its durability by 3 times, and polyacetylene – only by 1.5 times, which is also a quite good result.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
