Textiles-Detection and Evaluation of Sweat Stain Resistance-Drop Method

This standard specifies a method for testing and evaluating the sweat-stain resistance of textile products using the drop test method. It outlines the necessary procedures for preparing specimens, applying controlled droplets of sweat simulation solutions, and assessing the resulting staining on the fabric surface. The test environment, solution composition, and evaluation criteria are defined to ensure consistency and reproducibility of results across different laboratories. This approach allows manufacturers and quality control personnel to determine how well a textile maintains its appearance after contact with perspiration-like fluids. The methodology covers the visual assessment techniques and provides guidance on classifying the degree of staining according to established scales. By following the outlined steps, users can obtain reliable data regarding the performance of materials under conditions simulating human sweat exposure. The procedure is applicable to a wide range of textile goods intended for wear in situations where perspiration may cause visible discoloration or damage to the fabric finish.
