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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
