4th Central European Conference 2005, Fibre-Grade Polymers, Chemical Fibres and Special Textiles, Liberec, Czech Republic, Liberec, Czech Republic, 7 - 09 September 2005
In recent years, the antimicrobial finishing is widely used in textile industry because of increasing public awareness of hygiene and of the potentially harmful effects of micro-organisms. To combat bacteria, the chlorine containing organic products as well as the inorganic products based on silver and quaternary ammonium salts are employed.
The purpose of this research was to study the antimicrobial activity of Nylon 6/Lycra and Nylon 6,6/Lycra (92/8 %) knitted fabrics treated with quaternary ammonium salts which were commercial products of two local companies. These fabrics were tested against common pathogens, namely, Staphylococcus epidermidis, Group B Streptococcus, Candida albicans.
The antimicrobial agents (GEMSAN AEM 5772/5X and SETAS Ultra-fresh NM-V2) at different concentrations (20, 40 and 60 g/L) were applied to the samples of 18 g each by a padder, Roaches Padder BVP, and the condensations were carried out on a stenter (Ernst-Benz). The wet pick-up was 80% and the pre-drying was carried out at 100°C and the condensation was at 150°C for 1 minute. The measurement of the antimicrobial activity was performed by “the dilution method”. The grow rate of the bacteria (Staphylococcus epidermidis, Group B Streptococcus, Candida albicans) was determined.
