The purpose of this study was to evaluate the mechanical and comfort properties of fabrics for the development of fire-retardant work clothes. Specimens used in this study included six fire-retardant and welding work clothes and one fire-retardant fabric. Although all samples were made of cotton, samples A, B, and C had fire-retardant textile certifications. In addition, sample G was a fire-retardant fabric with conductive threads. The mechanical properties of all specimens were measured using the Kawabata evaluation system for fabrics (KES-FB). Results showed that A, B, C, and G had low values, in terms of tensile properties, of tensile energy (WT), but excellent shearing and bending properties. Thick cotton working clothes were observed to have high shearing prepertics, and as to surface properties, twill fabrics were found to have smoother texture. For the comfort properties of fabrics, A, B, C and G had high $Q_{max}$ and thermal conductance values, therefore they were better in terms of cool touch. However, they were found to have low air permeability.

Cotton fabrics were treated with tetrakis(hydroxymethyl)phosphonium chloride-urea precondensate via pad-dry-ammonia curing to reduce the flammability of the fabrics. Optimum finishing conditions were investigated for durable flame retardancy including the physical properties such as tensile strength and color fastness to washing. The fabrics treated by this technique showed excellent durable flame resistance, higher tensile strength, and a slightly lower tearing strength in comparison with the untreated fabric.

As the use of high-performance and highly functional industrial fibers has rapidly increased, the amount of the resulting fiber waste has also risen. The purpose of this study was to develop methods for recycling aramid/cotton-blend fabric and characterize its use in flame retardant work clothes. For this purpose, we investigated its properties through Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA), and performed a comparative analysis of the mechanical properties of the fabric with a KES-FB system. The recycled fabric retained the properties of both the cotton and aramid fibers. When compared with pure aramid fabric, the recycled aramid/cotton-blend fabric was more flexible, had a higher Qmax and thermal conductance, and a similar level of water vapor permeability. These results indicate that the recycled aramid/cotton fabric is comfortable to wear. This study also established a database that can be referenced for the utilization of recycled, aramid/cotton-blend fabrics in flame retardant work clothes.
