A novel real time evaluation of the uniformity of high-loft nonwovens using patented in-line measurement technology is introduced. Autins Group, a specialist in thermal and acoustic materials for the automotive industry, utilizes data acquired by a patented Hammer-IMS industrial basis-weight scanner and a modified uniformity index algorithm, origi- nally developed for full-area camera images, to provide a standardized approach for assessing nonwovens uniformity. The use of this technique was tested at Autins facilities in Tamworth/UK which is currently the only nonwovens supplier in the automotive industry to implement it and offer such a high level of quality control. The importance of non-wovens uniformity in automotive applications, the manufacturing challenges, and the potential for standardization in the industry is shown.
