Zinc Stannate Nanostructure: Is It a New Class of Material for Multifunctional Cotton Textiles?

Abstract

This study demonstrates the synthesis of nano-zinc stannate and its application as a novel multifunctional finishing agent on cotton fabric. Nano-zinc stannate has been synthesized by the co-precipitation method, and the nanostructures produced have been characterized to investigate their morphology and microstructure by using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction techniques. The synthesized nano-zinc stannate has been applied on cotton fabric and the multifunctional efficacies of the treated fabric, like UV resistance, antibacterial property, self-cleaning, as well as thermal stability, were analyzed. The as-synthesized zinc stannate-treated cotton fabric showed excellent efficiency in self-cleaning, antibacterial property, and flame-resistant action compared to the annealed nano-zinc stannate-treated cotton fabric. It was observed that the ultraviolet protection factor of the treated (annealed zinc stannate-treated) fabric shoot up more than 45 after treatment, and the same fabric showed more than 90% bacterial resistance against both Gram-positive and Gram-negative bacteria. Concerning thermal kinetics, the as-synthesized zinc stannate-treated fabric registered a 39% reduction in the peak heat release rate compared to the untreated cotton fabric, and it also showed catalyzed pyrolysis action and more amount of char mass (30–40% more compared to the control cotton) formation at higher temperature. The self-cleaning efficacy of the treated fabric has been examined against coffee stain and basic methylene blue dye. The treated fabric exhibited a good efficiency in cleaning of stain due to the free-radical scavenging behavior. Finally, it also has been proved that the integration of these nanostructure did not have any detrimental effect on the important physical properties (tensile strength, flexibility, and crease resistance) of the treated fabric.

Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2020

“…All reported data confirm the efficacy of this approach in increasing UPF of fabrics. Often, the nanoparticles used are selected for other improvements in fibre quality, such as better antibacterial properties or electrical conductivity, thus creating a multi-functional fabric [ 469 – 472 ]. Other metal oxides, such as NiOx nanoparticles in gas-sensing cotton fibres [ 473 ] and SiOx nanoparticles in superhydrophobic cotton [ 474 , 475 ], are used to obtain specific functionalities, although they also improve UV-shielding properties.…”

One-step green synthesis of eco-friendly novel N–P synergistic flame retardant for cotton fabric

“…In recent years, along the global human desire for environmental friendliness, many researchers mainly focused on eco-friendly ame retardant by utilizing natural raw material(e.g.bio-based DNA coating (Luo et al 2020), phytic acid/chitosan (Cheng et al 2019), banana pseudostem sap (Kambli et al 2018), casein (Xu et al 2019), nacre (Xie et al 2019), citric acid (Taherkhani and Hasanzadeh 2018), lignin (Shukla et al 2019) andxylitol (Wang et al 2019)etc. )as one of the components to synthesize no poisonousness ame retardant for combustiblematerial (Paul et al 2019). However, the dosages ofnatural resource materials are very limited.…”
