Abstract

The research aims to determine the effect of the treatment of gauze fabrics with Ammonium Chloride and Tannic acid and to achieve the most suitable treatment for each of them. Also, the best treatment materials under the research with chitosan at 5 g / L were obtained to improve the performance properties of gauze fabrics, Fabrics of gauze of different weight (light - heavy). The fabrics produced at different concentrations of ammonium chloride and tannic acid (10% -15% -20%) were treated separately and each treated with 5% / 5% chitosan. The drying was done at room temperature with some laboratory tests of the produced gauze fabrics Treated and untreated (weight per square meter, water absorption, microbial tests, growth of Escherichia coli and Staphylococcus, electronic scanner). The results showed that the treatment of heavyweight gauze fabrics (tannic acid + chitosan 5 g / l) and the concentration of tannic acid (20%) was the best produced for all different performance properties with an ideal area of ​​400 and 100% The samples produced under the research were light gauze treated with ammonium chloride, with a concentration of 10% with an ideal area of ​​168.90 and a quality coefficient of 42.22%. The results showed a marked improvement in most measured properties, especially inhibition of treated bacteria, Non-treated non-resistant to the bacteria
