Porometry testing techniques have undergone tremendous development in the last few years. Many of the recent innovations in pore characterization were specifically designed to improve product testing and development in the paper and other nonwoven industries. Recent advances include automated testing for improved reliability and accuracy. Additionally, ease of porometer use has been greatly improved with the implementation of MS Windows software. A thorough understanding of porometry testing techniques is imperative for optimal pore materials testing: both pore type and information sought concerning the properties of a material need to be considered. Porometry testing is ideally suited for testing of paper and other nonwoven materials. Studies have shown that companies using accurate pore characterization techniques can gain a competitive edge in their respective market. More research and development is underway which will continue to improve porometry versatility in the nonwovens industry.
