The history and evolution of “the forever molecule” is both revolutionary and fortuitous. Polytetrafluoroethylene, or PTFE, was discovered completely by accident on April 6th, 1938 by a DuPont Chemist, Dr. Roy Plunkett, while he was conducting research on chlorofluorocarbon refrigerants. Its first broad commercial use was non-stick cookware in 1960. PTFE has since evolved and is utilized in an extensive array of products that take advantage of its unique properties.

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 …
