Textiles being more vulnerable to microbial attack would cause cross infection, transfer of diseases, allergic reactions and odour upon human beings due to infestation by microbes. In order to overcome such bad effects antimicrobial treatment are needed to apply on the textile materials. Therefore, cotton fabric was treated with Peach leaves extract to assess its efficacy against antibacterial property and washing. Effect of preparatory processes, Peach leaves extract treatment and washing on physical properties was also assessed. For effective application of treatment, desizing and scouring was done. Peach leaves were extracted by cold aqueous maceration. Yield percentage of aqueous extract of 24 hrs. (20.11%) was found to be higher than 12 hrs. (9.20%). Three concentrations i.e. 1mg/ml, 3mg/ml and 5 mg/ml were tested against the growth of Bacillus spp. Strong zone of inhibition was observed in 5mg/ml concentration. The application of treatment was performed with exhaust method by using the standard conditions. On 0 day (soon after 24 hrs.) of inoculation Peach leaves extract treatment was found to be cent percent effective with both the dilution factors (107 and 108). Treatment was very effective even up to a week period, however there was reduction in percent reduction with increase in incubation period. After washing it was found that Peach leaves extract treatment was effective but there was decrease in percent reduction with an increase in incubation period. However, it is needed to retreat the fabric samples after every wash. After desizing and scouring fabric weight, bulk, fabric count both in warp & weft directions and thickness of fabric were increased significantly while air permeability, bending length in weft direction were decreased significantly. The changes in bending length in warp direction, tensile strength both in warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. After Peach leaves extract treatment bulk and weight of fabric were increased significantly while air permeability and tensile strength in warp directions were decreased, significantly. The changes in tensile strength in weft directions, fabric count both in warp and weft directions, thickness, bending length both in warp and weft directions, flexural rigidity and moisture regain were found to be non- significant. After washing fabric weight, bulk, tensile strength in warp and weft directions, thickness and bending length in weft direction were decreased significantly while air permeability increased significantly. The changes in bending length in warp direction, fabric count both in warp and weft directions, flexural rigidity and moisture regain were found to be non-significant. Conclusively, Peach leaves extract was observed as a effective natural source for antibacterial activit.enExtraction, Peaches, Economic resources, Cotton, Bacteria, Sampling, Concentrates, Processed products, Planting, Biological developmentThesis
