Imparting biocidal properties to insulating materials made of linen fibres

In this work, salicylic acid and copper sulfate were chosen as antimicrobial agents to impart biocidal properties to nonwoven materials. The conditions of the antibacterial finishing process were as follows: the aqueous solution of a biocidal composition of different concentration was applied by spraying to the surface of the material, then the drying and heat treatment was carried out at 180°C on the thermal conductor. A microbiological study was conducted to study the fungicidal activity of the treated material. Tests were also carried out on the toxic and dermal effects of non-woven material treated with salicylic acid and copper sulfate and demonstrated its safety to human health.
