Performance Textiles and Fabrics: Assessing and Verifying Product Performance Claims Executive Summary
PERFORMANCE TEXTILES AND FABRICS: ASSESSING AND VERIFYING PRODUCT PERFORMANCE CLAIMS EXECUTIVE SUMMARY Performance textiles and fabrics are rapidly bringing apparel and footwear products into the 21st century. Manufacturers today are innovating at breakneck speed and bringing to the market synthetic textiles and fabrics with enhanced performance characteristics, or that feature embedded fibers or topical applications. This has led to the widespread introduction of advanced performance apparel and footwear that offer consumers new levels of comfort and safety. At the same time, sorting through claims regarding the performance characteristics of these advanced textiles and fabrics can present real challenges for manufacturers, retailers and consumers. At a minimum, the myriad of vague, conflicting or unsubstantiated marketing claims and characterizations used to promote these materials often result in frustration and disappointment. And fraudulent representations can unnecessarily expose apparel manufacturers and retail buyers to potentially hazardous chemicals and other risks. This UL white paper identifies some of the key performance considerations for advanced textiles and fabrics, and reviews the challenges of vague or unsubstantiated marketing claims used to promote these products. The white paper also discusses the importance of verifying performance claims, and offers an overview of UL’s marketing claim verification services for performance textiles and fabrics. page 2 BACKGROUND Performance textiles and fabrics are generally defined as materials that have been expressly designed and produced to include or to enhance specific performance characteristics, such as increased warmth, durability or moisture resistance. These new or enhanced performance characteristics are typically achieved through the selection of specialized fibers, or the inclusion of such fibers along with natural or synthetic materials during the spinning, weaving or knitting process, or by the addition of coatings or other finishes to the finished fabric. -

A User's Guide to Co-Ops Visibility Sensor
A USER’S GUIDE TO CO-OPS VISIBILITY SENSOR OBSERVATIONS The American Meteorological Society defines visibility as “the greatest distance in a given direction at which it is just possible to see and identify with the unaided eye (a) in the daytime, a prominent dark object against the sky at the horizon, and (b) at night, a known, preferably unfocused, moderately intense light source. A wide variety of factors contribute to changing this distance. CO-OPS deploys automated visibility sensors at locations selected in concert with supporting PORTS® partners. The sites must be both acceptable for sensor operation and useful for the user. Because fog can be patchy, it is important for users to understand how to interpret the disseminated data. The sensors used by CO-OPS optically examine a small volume of air to determine the scattering characteristics of the air parcel, the most common technique used to measure visibility. Scatter can be caused by fog, smog, dust – any particles in the air will suffice. When the scatter is small the visibility is good, while large scatter means the visibility at the location of the sensor is poor. It is important to realize that the visibility range provided by the sensor, more correctly known as Meteorological Optical Range (MOR), is a measurement made at a single point. When fog or other scattering particles are uniformly widespread it may be reasonable to presume the MOR applies over large distances, ie. a reading of 5 nautical miles means a person will see sufficiently large objects at that distance. But such a presumption may not be valid, and the sensor has no way of observing MOR except at the deployment site. -

Reduced visibility is an indicator of poor air qual- in aerosol particle properties. This approach may help con- ity. Moreover, degradation in visibility can be hazardous to strain global model simulations which attempt to generate human safety; for example, low visibility can lead to road, aerosol fields for time periods when observational data are rail, sea and air accidents. In this paper, we explore the com- scarce or non-existent. Both the measured visibility and the bined influence of atmospheric aerosol particle and gas char- modelled aerosol properties reported in this paper highlight acteristics, and meteorology, on long-term visibility. We use the success of the UK’s Clean Air Act, which was passed in visibility data from eight meteorological stations, situated in 1956, in cleaning the atmosphere of visibility-reducing pol- the UK, which have been running since the 1950s. The site lutants. locations include urban, rural and marine environments. Most stations show a long-term trend of increasing visi- bility, which is indicative of reductions in air pollution, es- pecially in urban areas. -

Recent studies have indicated that the deeper oceans are responsible for climate variability by changing the Earth’s ecosystem; therefore, assessing them has become more important. Remote sensing can provide sea surface data at high spatial/temporal resolution and with large spatial coverage, which allows for remarkable discoveries in the ocean sciences. The deep layers of the ocean/sea, however, cannot be directly detected by satellite remote sensors. -
