Performance of three flame-retardant finished, bottom-weight fabrics as measured by in-field service and laboratory testing

The purpose of this study was to investigate the performance of selected bottom-weight, flame-retardant fabrics for use in career apparel. Performance was defined to include flame resistance, durability, and aesthetic properties of fabrics. Fabrics selected for study were twill-weave constructions of 100% cotton, 50/50 polyester/cotton intimate blend, and 100% polyester. One flame-retardant treated and one untreated fabric of each fiber content were studied. Laboratory measurements of performance characteristics were made after subjection of fabric to in-field service and repeated launderings. Subjective measurements of performance were obtained by wearer assessments of garments constructed from test fabrics. Mean values of data collected were compared to minimum requirements of selected performance standards. Data collected were evaluated statistically using analysis of variance and Scheffe’s formula for pairwise comparisons. Results of flammability testing were evaluated on the basis of established pass/fail criteria
