    Use of rooted hydrophytes in developing innovative functional textiles
    (Wydawnictwo Politechniki Łódzkiej, 2022) Sharan, Madhu; Haldar, Sumi
    The study attempts to experiment with the nelumbo nucifera (pink lotus) category of rooted hydrophytes. In India, a lotus flower has a huge economical importance that it is used for worshipping. It was observed that lotus cultivators generally cut the flowers with little length of the petioles leaving the rest as a waste in the pond. Petioles contain bundle of microfibers and natural gummy substance called as mucilage which is useful for medicinal applications. In recent times, resistance against the bacteria has become a need of an hour. Researchers have developed the method for preparing non-woven sheet from lotus fiber. This sheet was subjected to qualitative antibacterial test (AATCC 147) against four organisms - Staphylococcus aureas, Klebsiella pneumonia, Candida Albicans and Pseudomonas aeruginosa. The results have shown positive bacteriostatic antibacterial activity against all the above organisms which proves that lotus fiber can be further taken for medical textiles.

    In-situ green synthesis of zinc oxide nanoparticles (ZnO NPs) onto the cotton fabrics by neem (azardirachta indica) leaf extract
    (Wydawnictwo Politechniki Łódzkiej, 2022) Javed, Asif; Wiener, Jakub; Saskova, Jana; Militky, Jiri
    This research work was carried out for the green in-situ synthesis of ZnO nanoparticles onto the 100% cotton fabric. Zinc nitrate hexahydrate [Zn(NO3)2.6H2O] was used as precursor and the Neem (Azardirachta Indica) leaf extract was used as reducing agent. Scanning electron microscopy (SEM) and X ray diffraction (XRD) were done to investigate the surface morphology and characteristics of developed samples. Moreover the ultraviolet protection factor (UPF), UVA blocking %age, UVB blocking %age, and antibacterial properties were examined. The SEM and XRD confirmed the deposition of ZnO NPs onto the fabric having crystalline structure. The evaluated samples showed very excellent results for, UPF rating, UVA blocking %age, UVB blocking %age, and antibacterial properties.
