Computerized Approach to Evaluating the Performance of Heat Resistant Protective Fabrics

摘要

Laboratory tests were performed on various materials which might prove to be useful for making industrial safety apparel. The test materials included flame resistant cotton, rayon, and fabrics from polyaramids, novoloids, modacrylic, polybenzimidazole, and stabilized acrylic fibers. Tests were performed to evaluate the durability and performance of the textile samples, and a computerized model was developed to handle the information obtained and make systematic comparisons among fabric samples. The goal for the computer system was to compare fabrics in specific categories based on user judgements concerning what constitutes acceptable performance in the field. With Harrington's analytical model it was possible to compare thermal protection, stiffness, weight, permeability, tear strength and grab strength levels of the samples. The test fabrics spanned a wide range of physical properties. The system is unlimited with regard to the nature and volume of input data that it can handle. Additional factors which might be included in the future are not only additional tests and fabrics, but information concerning price of the materials as well.
