Application of grape seed coating for antibacterial cotton fabric

Microorganisms can reproduce rapidly on textile surfaces. It is known that textile surfaces used especially in hospitals cause the spread of infections and pose a danger. In recent years, instead of synthetic and heavy metal applications, the interest in obtaining environmentally friendly and natural plant-based antibacterial materials and textile applications has been increasing day by day. Grape skins and seeds, rich in polyphenolic compounds, are waste products from winemaking. The evaluation of such waste products is of great importance. In this study, grape seed, which is stated to have antibacterial activity in many studies, was applied to cotton textile material with the coating method and it was aimed to gain antibacterial properties to the fabric. As a result of the colour fastness tests performed according to the ISO 105-C06 standard, it was not observed that the coating process had a negative effect on the washing fastness of the fabrics. The wash fastness value of all coated fabrics is 5. As a result of the washing fastness test, it was seen that the coated fabrics were resistant to washing. As a result of the friction fastness tests performed according to the TS EN ISO 105-X12 standard, it was observed that the coated fabrics were resistant to friction. When the breaking strength and breaking elongation values of the coated fabrics were examined as a result of the strength test performed according to the TS EN ISO 13934-1 standard, it was observed that the tensile strength and elongation at break of the coated fabrics increased. Antibacterial tests against E. coli and S. aureus bacteria were performed on treated fabrics according to the AATCC 100 antibacterial test method. It is obtained as a result of the coating process for 60% coverage. As a result of the coating process, better results were obtained against E.coli bacteria. It was observed that the antibacterial properties improved as the coating rate increased. As a result of the tests, antibacterial activity was provided against both bacteria. An acceptable level of antibacterial activity was detected in the antibacterial tests of the washed fabrics.
