We discuss how N95 and surgical facemasks induce significantly different temperature and humidity in the microclimates of the facemasks, which have profound influences on heart rate and thermal stress and subjective perception of discomfort.

Surgical masks can provide in-vivo filtration protection of 95% filtration efficiency. N95 respirators provide higher in-vivo filtration efficiency of 97% with significant reduction of air permeability and water vapor permeability. Compared to normal surgical masks/respirators, the nano-masks can provide additional protective functions in stopping capillary diffusion and antibacterial activities.

Metalization is one of the finishing processes in textile treatments that can produce fabrics with a unique appearance. It has great potential for textiles and garments, including functional and decorative effects. Chemical plating is an autocatalytic deposition method for precision work in conventional manufacturing. In this study, the operation and final properties of the chemical silver plating of cotton and polyester fabrics were investigated. The results showed that a specific performance of silver-plated fabric could be obtained if the optimum chemical-plating conditions were chosen. In addition, a fabric design practice employed by this chemical technique with a craft approach achieved a diverse effect.
