“…However, carbon also reduces the moisture vapor transport (MVTR) through fabric composites . A high MVTR is essential to maintenance of evaporative cooling from the skin, which reduces the chance of heat injury and increases the work/rest cycle of first responders and the military . Other shortcomings with carbon include durability and susceptibility to poisoning by battlefield contaminants .…”

Currently, air permeable chemical/biological (CB) protective garments are based on activated carbon technology, which reduces moisture vapor transport needed for evaporative cooling and has potential to absorb and concentrate toxic materials. Researchers are exploring classes of sorbent materials that can selectively accumulate and decompose target compounds for potential to enhance protective suits and allow for novel filtration devices. Here, the metal–organic frameworks (MOFs) UiO-66-NH2 and HKUST-1 have been identified as such materials. To better understand how MOFs can perform in future CB protective systems, atomic layer deposition (ALD) and solution deposition were used to modify nonwoven polypropylene and flame-resistant fabrics with HKUST-1 and UiO-66-NH2. Air permeation, water vapor transport, filtration efficiency, and chemical reactivity against chemical agent simulants were assessed in relation to ALD thickness and MOF crystal size. MOF deposition on substrates decreased both air and chemical permeation while increasing filtration efficiency and chemical sorption. Moisture vapor transport was not affected by MOF growth on substrates, which is promising when considering thermal properties of protective garments. Future work should continue to explore how MOF deposition onto fiber and textile substrates impacts transport properties and chemical absorbance.

Chemical protective clothing is widely used by emergency teams in certain industries and such as fire-fighting and medical protection fields. Due to the differences of assessment, specific requirements for target products, and test methods, the relevant standards for such clothing vary greatly. By analyzing standards on chemical protective clothing, this study summarized their differences in assessment items and test methods for basic performances such as seam strength, leak tightness, permeability by liquid/gas chemicals, resistance to ignition, liquid repellency and penetration by liquids.

“…Also, they declared that to investigate the behaviour of climatic change on the thermal resistance of rowing t-shirts, the thermal manikin tests must be conducted in different air temperature and humidity conditions. Xu X, et al [24] a sweating thermal manikin was used to calculate the thermal (Rcl) and evaporation resistance (Recl) and they investigated the effects of fabric structure on the thermal and evaporation the resistance of chemical protective garments. The results showed that measurements of the sweating hot plate and thermal manikin provide a new look for understanding the relation between fabric and clothing.…”
