Abstract
The aim of this study was to develop a new, original method for obtaining the anti-microbial finishes through the creation of silver nanoparticles “in-situ“, on and in cotton fabrics. The choice of cotton fabrics was dictated by the fact that fibers are hydrophilic and containe in their structure empty spaces (both in the fiber, in the yarn as well as in flat textile product), thus enabling the antibacterial finishing of textiles from the aqueous medium and the introduction of a biocide not only on the fiber surface but also inside them. The unique properties, which displays the nano silver particles allowed to obtain finishes exhibiting biocidal properties against strains of Escherichia coli, Bacillus subtilis and Staphylococcus aureus. Development of biocide application method using printing techniques enabled the local application of silver nanoparticles and the production of different batches of material, depending on customer needs.
In this study a wide range of modern research techniques, which confirmed that these finishes is characterized by the slight migration of the biocide from the finished fabric during the textile conservation, and long-lasting durability of the washing processes, indescribable until now in literature, were used.
