Research on the novel medical protective clothing for COVID-19

Gradient Design of Spunbond-Meltblown-Hydroentanglement Composite Nonwovens for Directional Water Transport

“…Although the breathable-moisture permeability index is presented in the materials, during the actual wear state with high intensity exercise, the personnel move in the space of closed clothing, the sweating rate is very high. Due to the excellent liquid barrier properties of the protective material, its antiliquid protection function effectively prevents water penetration, leading to the accumulation of liquid water or sweat in the inner layer of the clothing, and the inevitably increased volume of sweat, moisture, inhibiting heat loss. , The wearing comfort of protective clothing has prompted an increasing number of scholars to conduct in-depth studies in this field. Na et al utilized electrostatic spinning and spraying technology to produce a double-gradient structured, moisture-wicking protective fiber membrane.…”

Water-blocking Asphyxia of N95 Medical Respirator During Hot Environment Work Tasks With Whole-body Enclosed Anti-bioaerosol Suit

“…The global pandemic of respiratory infectious diseases such as severe acute respiratory syndrome, Middle East respiratory syndrome, and novel coronavirus pneumonia (NCP) are mainly transmitted by virus through droplet aerosols respiration and/or contagion, which are characterized by highly infectious, high morbidity, and rapid mutation of virus strains, posing a serious threat to people's life and health [ 1 , 2 ]. During the pandemic outbreak, wearing N95 medical respirator is one of the effective ways to prevent viral infection, while healthcare workers (HCWs) working in high-risk environments need whole-body protection (N95 medical respirator + one-piece protective suit + head covering + protective face screen + gloves + shoe covers) [ 3 ]. Although whole-body protection provides both respiratory protection and contact prevention, it has the drawbacks of poor air and moisture permeability [ 4 ].…”
