Cellulose/polyester bi-layer functional fabric to develop pesticide-resistant comfortable PPE

Wearing appropriate personal protective equipment (PPE) for spraying pesticides is one of the methods to reduce dermal exposure to toxic pesticides. The main issues with such PPEs are comfortability and durable functionality. These issues were addressed by developing a bi-layer fabric treated with functionalized iron molybdate (Fe 2 (MoO 4 ) 3 ) nanoparticles (NPs). Three structures of bi-layer fabrics were developed to get the most comfortable fabric one with an upper layer of cotton (1*1 woven) and an underlayer of polyester (3/1 twill weave). The Fe 2 (MoO 4 ) 3 NPs were synthesized and functionalized with two silanes, i.e., Octadecyltrimethoxysilane and 1,2 Bis(triethoxysilyl)ethane. Fourier transform-infrared spectroscopy and thermogravimetric analysis were done to confirm the binding of silanes with NPs. Functionalized Fe 2 (MoO 4 ) 3 NPs were coated on selected fabric by dip-dry coating, and surface topography was assessed by Scanning Electron Microscopy (SEM). The water contact angle of 151° was exhibited by modified fabric. The photocatalysis of Benzoepin (C 9 H 6 Cl 6 O 3 S) by Fe 2 (MoO 4 ) 3 NPs under visible light was 75%. The UPF values obtained were 55 and 50 before and after washing, respectively. The developed superhydrophobic fabric could be efficiently used for durable pesticide-resistant clothing because the pesticide would not be adsorbed/absorbed by the fabric. If absorbed it could be possibly degraded by Fe 2 (MoO 4 ) 3 NPs rescuing the wearer from the hazardous effects of pesticides as well as UV rays. Graphical abstract
