Abstract :

<p> Due to suitable climate provided by the skin, the problem of infestation was aggravated in textile materials worn, especially under garments. Bio–synthesized guava leave nanoparticles were used to treat woven and knitted cotton to impart antimicrobial (antibacterial and antifungal) property. Bio–synthesized Guava leaf nanoparticles were analyzed using UV– spectrophotometer which showed a wave–length of 423–437nm with an absorbance of 2.34 suggesting the formation of 50–200nm size nanoparticles and TEM analysis confirmed nanoparticles size with 51.8nm. 5 percent nanoparticles treatment on woven and knitted samples were treated with two methods; padding and drying at room temperature (T1) and a pad–dry–cure method at 800 C (T2) were assessed for antibacterial activity against E.coli and S.Aureus following AATCC 147–1998 and antifungal activity following AATCC 30–1993 test methods, which showed T2 treated samples have good antimicrobial activity than T1 treated samples in both type of textile materials. Even after 5–10 launderings T2 treated samples have antibacterial property, where there was no fungal growth was observed. Analysis of faics geometrical parameters showed an increase in yarn count, faic count, thickness and faic weight.</p>
