Abstract:

This article considers the development of a new polymeric composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid for the antimicrobial finishing of cotton fabrics. The advantages of the application of a new composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid include the availability of the material’s use, as well as the simplicity of the technological process: finishing may be performed with any tenter drier aggregated with a padding machine and combining the drying process and thermal treatment. The newly developed efficient composite formulation for biocidal finishing of cotton fabrics is comparatively inexpensive, environmentally safe, and resistant to wet treatment. Its application offers opportunities of manufacturing of a wide range of competitive, environmentally compatible, and biologically stable cellulose textiles with various textures and various fabric weights. As a result of the study it has been found out that cotton fabrics finished with the composition on the basis of polyvinyl pyrrolidone, silver ion solution and benzoic acid have advanced antimicrobial characteristics preventing fouling with mould fungi and are not deteriorated by microorganisms under operational conditions.
