Novel multi-functional finishing of cotton fabrics to impart high performance properties

Abstract

The finishing textile industry causes serious pollution to the environment during the process of the production. Pollution prevention is the main strategy aim to develop new green methods and processes for the preparation of nano chitosan, which are environment-friendly and suitable for low-cost industrial applications. In this thesis, the research study was divided mainly on three part: - Firstly, Chitosan nanoparticles were prepared by using tri poly phosphate and characterized using FT-IR and TEM -pH and ultra-sonication time were kept constant at 5.5 and 45 min. respectively; based on previous studied - The optimum conditions of preparation of chitosan nanoparticles are: chitosan concentration is 0.2 g/ml, TPP concentration is 0.1 g/ml, ultra sonication time is 45 min. at pH is 5.5. - Chitosan nanoparticles were loaded with selected antibiotics (ciprofloxacin HCL, Chlortetracycline hydrochloride and Gentamycin sulfate) to overcome the side Summary 239 effects of these antibiotics and magnify their benefits in biomedical applications. - Antibacterial activity of chitosan nanoparticles loaded with antibiotics increase with increasing the antibiotic concentration. - Chitosan nanoparticles exhibit higher antibacterial activity against Gram-positive bacteria than Gram-negative bacteria. - Order of inhibition for three antibiotics are: Gentamycin sulfate˃ ciprofloxacin HCL ˃ Chlortetracycline hydrochloride
