Liquid crystal polyester (LCP) filament yarns made from thermotropic liquid crystalline polymer are a type of “super fiber,” which include para-aramid and ultra-high molecular weight polyethylene (UHMWPE).Since the mass production of LCP filament yarns began in the 1990s, demand has expanded owing to their unique characteristics, such as high tenacity, high modulus, low water absorption and heat resistance.

In this work, we investigated the suitability of a bio-based elastomer to modify polylactic acid (PLA) towards more elasticity, in combination with a reactive coupling agent. We found that this is possible in general, but the processing of the materials has to be carried out with care so as not to locally cross-link the materials, which would result in a reduction of properties.
With global fiber production now exceeding 100 million tons – and growing at 3-4% a year – non-governmental organizations (NGOs), which focus on all parts of the textile value chain, are increasingly drawing attention to the fiber industry and producing unfavorable, critical reports. Textile products are placing huge pressures on the Earth’s resources and polluting the environment.
Techtextil North America 2019, in Raleigh, North Carolina, February 26-28, will be the first edition to name an official academic partner. North Carolina State University’s College of Textiles, located minutes from the Raleigh Convention Center in Downtown Raleigh, serves as a hub for textile research and development and as a primary supplier to the industry …
The scientific employees Dr. Valentine Gesché, David Schmelzeisen and Kristina Simonis of Institut für Textiltechnik (ITA) of RWTH Aachen University under the leadership of Prof. Thomas Gries, won the RWTH Innovation Award for their project “4D textile – additive manufacturing of hybrid materials for temporarily shape shifting applications.” In this project, microstructures were printed in …
