Normally it’s utilized to material at the finishing stage of production. As several treatments may be concurrently applied, no extra water or energy is required and the influence on the surroundings is decreased.
Face masks may be made from such supplies utilizing known mask-making processes, e.g. moulding / folding. Accordingly in a further aspect of this invention a process for making a face masks is offered comprising providing a filter material as described herein and forming the filter material right into a face mask. The polyester material used was a proprietary nonwoven cloth made up 100% of polyester fibres, designated by its supplier a hundred % polyester gsm NT MSQ 180G/M2 BLANC LZE MM non woven fabric. Material of various weights had been utilized in experiments, one hundred eighty, 80 and 70 g/m2 The color of the fabric was white or anthracite gray .
Air exhaled by infected patients is a supply of contamination. At the present time the risk of infection by the so referred to as “chook flu” H5N1 virus is of specific concern.
