There is a permanent demand for improvement of protective fabrics. More in particular there is much interest in flexible body armour that offers excellent protection properties against lethal projectiles and explosive fragments while maintaining comfort properties such as light weight, flexibility and vapor permeability. Several methods have been investigated. The usual method to increase protection is to add more layers of fabrics or ceramic inserts at the expense of increased weight of the armour and reduced mobility of the wearer. Alternatives like impregnation with shear thickening fluids containing nanomaterials have been proposed to avoid this decrease of flexibility. We propose a new method to deposit nanoparticles individually on textile fibres using an atmospheric pressure dielectric barrier discharge plasma. Nanoparticles are injected via an ultrasonic nebuliser in the plasma reactor where they are coated with a thin polymer layer. Initial results of innovative method are presented by characterisation of particle coated textile fabric samples of cotton, polyethylene and aramid.
