Teijin Limited announced today that it has developed a water-resistant, wet-strong printing paper made entirely with the company's ECOPET recycled polyester fiber derived from used PET (polyethylene terephthalate) bottles. http://phys.org/news282472591.html Chemistry Thu, 14 Mar 2013 09:36:41 EST news282472591 VTT Technical Research Centre of Finland has developed a process that enables recycled paper and cardboard to be used as a raw material for nonwovens. Hygiene and home care products, such as nappies, sanitary towels and cleaning cloths, are among the many items that can be manufactured from the biodegradable nonwovens. The manufacturing costs of cardboard-based nonwovens are around 20% lower than for nonwovens produced from wood raw materials. The forest industry will be among those likely to benefit from new business opportunities opened up by nonwovens based on recycled paper and cardboard. http://phys.org/news282383292.html Chemistry Wed, 13 Mar 2013 08:48:19 EST news282383292 Najua Tulos and co-researchers of the Faculty of Applied Sciences, Universiti Teknologi MARA (UiTM), Shah Alam, studied the potential of chitosan to dye polyester fabric. Produced commercially by removing the acetyl groups from chitin (a derivative of glucose), chitosan was found to greatly improve the colourfastness of polyester fabrics. http://phys.org/news257674126.html Chemistry Thu, 31 May 2012 09:09:46 EST news257674126 Cotton is going high-tech in New Orleans, La., where a team of U.S. Department of Agriculture (USDA) scientists is continuing a long tradition of innovative research on the prized natural fiber. http://phys.org/news253963767.html Nanotechnology Wed, 18 Apr 2012 10:29:40 EST news253963767 (Phys.org) -- Despite significant advances, the development of synthetic biomaterials still presents significant challenges in the field of biomedical engineering. Although synthetic biodegradable materials such as polyester exist, most are biologically inert and lack functionality. Now, thanks to a research team at the University of Pittsburgh, a synthetic platform has been developed that will help produce diverse biodegradable materials for specific biomedical applications. These findings were published online in the March 30 issue of Advanced Functional Materials.  http://phys.org/news253429538.html Chemistry Thu, 12 Apr 2012 06:30:01 EST news253429538 Scientists are reporting that household washing machines seem to be a major source of so-called "microplastic" pollution -- bits of polyester and acrylic smaller than the head of a pin -- that they now have detected on ocean shorelines worldwide. Their report describing this potentially harmful material appears in Environmental Science & Technology journal. http://phys.org/news238248245.html Space & Earth Wed, 19 Oct 2011 13:04:27 EST news238248245 Nine teams competing in the World Cup will be wearing environmentally friendly jerseys made from recycled plastic bottles when the tournament kicks off in South Africa on Friday. http://phys.org/news195369723.html Space & Earth Thu, 10 Jun 2010 06:22:19 EST news195369723 Could powering an iPod or cell phone become as easy as plugging it into your tee shirt or jeans, and then recharging the clothing overnight? Scientists in California are reporting an advance in that direction with an easier way of changing ordinary cotton and polyester into "conductive energy textiles" -- e-Textiles that double as a rechargeable battery. Their report on the research appears in ACS' Nano Letters. http://phys.org/news183214328.html Nanotechnology Wed, 20 Jan 2010 12:52:25 EST news183214328 A vascular surgical technique pioneered at UT Southwestern Medical Center and designed to replace infected aortic grafts with the body's own veins has proved more durable and less prone to new infection than similar procedures using synthetic and cadaver grafts. http://phys.org/news181399154.html Medicine & Health Wed, 30 Dec 2009 12:39:53 EST news181399154 (PhysOrg.com) -- Engineers at Ohio State University have found a way to double the production of the biofuel butanol, which might someday replace gasoline in automobiles. http://phys.org/news169890707.html Chemistry Wed, 19 Aug 2009 08:57:34 EST news169890707
