PCM briefing: PureTemp joins RSPO; Reda's new PCM fabric on display in Milan

Ben Welter - Monday, February 18, 2019

PureTemp LLC has joined the Roundtable for Sustainable Palm Oil as an associate member. The nonprofit organization, which has more than 4,000 members worldwide, promotes the growth and use of sustainable oil palm products. In November, RSPO adopted stricter standards for certified sustainable palm oil, including a total ban on deforestation by its members.

Reda Group's new Active Phase temperature-control fabric was on display at the Milan fabric trade show earlier this month. The material uses phase change material to keep body temperature constant when ambient temperature fluctuates. Reda says the material features enhanced breathability and softness and is "easy to clean, even in water."

University of Maryland fabric•  University of Maryland researchers have created a temperature-control fabric that does not rely on phase change material. The fabric changes its insulating properties in response to the environment. In warm and humid conditions, the fabric allows radiant heat to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes. Two types of synthetic materials in the fabric — one that absorbs water and another other that repels it — are coated with carbon nanotubes. The fibers warp and relax in response to changing humidity, opening and closing pores in the fabric. 

• In interviews with Advanced Textiles Source, four entrepreneurs were asked: What do you wish you had known early on when you were first dealing with intellectual property law and patent issues? “Get feedback on why you need a patent,” said Jeremy Wall, founder and CEO of smart-clothing startup Lumenus. “Where else could you spend $20,000?” Said Matt Kolmes, CEO of VOLT Smart Yarns: “Even if you are on a tight budget, file that Provisional application immediately before you show your idea to anyone, or talk about it with anyone."

• The Marie Sklodowska-Curie Action program is seeking applicants for a one- to two-year research fellowship at the Oslo Metropolitan University. The European Union-funded fellowship will focus on the energy-performance aspects of phase change material in buildings. "In this collaboration," OsloMet says, "we intend to gain our understanding and explore about the micro-structural aspect to relate the macro-scale behavior at continuum level." The application deadline is March 7.
