  • Material-Level Evaluation of Particulate Filtration Efficiency (PFE)

    The nature of this assessment is to acquire fast, efficient, and repeatable results that can be used as an initial screening for assessment of material particulate filtration efficiency.
  • Impact Penetration Testing for Textiles Part 1

    Impact Permeation tests assess the resistance of fabrics to the permeation of water by impact. The test was designed to predict the probable rain permeation resistance of a fabric and most  procedures still include this language in the scope. The test has also been followed by the medical industry as an assessment of liquid barrier performance for protective apparel and drapes.
  • ISO 18184 – Determination of Antiviral Activity of Textile Products

    Standard mechanisms for antiviral activity need additives that can chemically or dynamically alter some aspects of the virus.  Drug strategies depend on distinctly specific binding to the virus (known as receptor-ligand binding) where the receptor is on the virus, and the ligand is the drug used to bind to the receptor obstructing its motive movement.
