In addition to that, they have great pressure resistance and tensile strength. What is more, the opportunity for 3-D shaping opens the possibility of creating completely new types of products.
Scientists at the textile research centre of the Hohenstein Institute in Boennigheim, have worked out key process parameters for the prototype of a laser sewing machine, the TexWeld 140 made by the Prolas company.
In conjunction with his Bachelor's thesis, Philipp Kirst of Albstadt-Sigmaringen University, worked with the project leader, Dr. Edith Claßen and her team in defining threshold values for temperature, speed and conveyor roll intervals as well as the use of absorbers while welding different textile materials.
In order to assess the quality of the seams beyond inspecting them visually, a comprehensive series of tests of the fusion zones were carried out with the help of a scanning electron microscope. Textile technology tests were also required primarily to test tear and water resistance.
A final showpiece was used to demonstrate the diverse possibilities opened by the laser welding of thermoplastic textiles of synthetic fibres or laminated materials. A surgical smock made of three-layered, laminated fabric featuring different straight and round seam structures revealed the full design spectrum of modern laser welding technology.
Dr. Claßen's team (firstname.lastname@example.org) will be investigating the possibilities of welding fabric blends in the coming months.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
