Nano-silver as antimicrobial: Is it safe?
June 1st, 2012
The Hohenstein Institute is part of the E.U.-based public research project “UMSICHT” (circumspection), and is developing scientific data to measure the impacts of nano-silver technology. Many unanswered questions exist concerning the behavior of nano-silver particles throughout the life cycle of in-market textiles treated with nano-silver, such as: Do the physical properties of the particles effect […]
Teijin develops first mass-production aramid nanofiber
May 18th, 2012
Teijin Techno Products Limited, a Teijin group company producing advanced aramid fibers, has announced its development of the world’s first mass-producible aramid nanofiber to offer reliable heat and oxidation resistance together with high quality. Until now, aramid nanofibers have been produced only in laboratories, so this first commercially viable product represents a significant step forward […]
NRDC says no to nanosilver
March 1st, 2012
Silver is widely used as an antimicrobial in textiles, but a lawsuit filed by the Natural Resources Defense Council (NRDC) against the U.S. Environmental Protection Agency (EPA) aims to halt antimicrobial nanosilver used in clothing, bedding and furnishings. In December 2011, the EPA decided to allow HeiQ Materials to use nanosilver in fabrics for four […]
Testing inhalation toxicity from nanoparticles
March 10th, 2011
The explosion of nanotechnology-based products and industries has raised increasing questions about the safety and environmental impact of nanoparticles, and the International Organization for Standardization (ISO) has a published a new international standard to support inhalation toxicity testing of nanoparticles. Entitled “Nanotechnologies—characterization of nanoparticles in inhalation exposure chambers for inhalation toxicity testing,” ISO 10808:2010 establishes […]
Nanotechnology: It’s getting bigger
January 2nd, 2011
Breaking the barriers to accepting—and selling—nano innovations in specialty fabrics markets There has been increasing momentum in recent years in the use of nanotechnology to provide textile products with new and enhanced properties, such as stain and water repellence, flame retardance, antimicrobial properties, UV protection, abrasion resistance, odor absorption and insect repellence. With such wide-ranging […]
