Abstract

Among the diverse fields of application of technical textiles, which are poised for tremendous growth in fastdeveloping economies like those of India and China, non-implantable healthcare and hygiene products are assuming significant importance because of specificity of their end uses. Protective textiles offer protection from hazardous chemicals, microbes, heat, extreme cold and radiation and have special application potential in today’s technologically advanced world. In addition to this, the advent of nanotechnology has opened innumerable new avenues giving rise to high-performance textiles and apparel. Today, the healthcare industry is increasingly concerned with the exposure and transference of various microorganisms that are commonly present in the atmosphere. Studies have been carried out in the present work to fine-tune the properties of zinc oxide nano-particles for special applications. In the current work, soluble starch (stabilizing agent), zinc oxide nitrate and sodium hydroxide (precursors) were used for the preparation of zinc oxide nanoparticles by wet chemical method. The zinc oxide nano-particles were microencapsulated and applied to single jersey cotton fabric. The antibacterial property of the coated fabric was determined quantitatively and qualitatively. Techniques such as Scanning Electron Microscopy (SEM) and physical and chemical characterisation were employed to study the phase and morphology of the nanoparticles. The results indicate that the coated fabric have high antibacterial efficiency. The nanoparticles synthesized in this work have an average size of 50 nm and the physical and chemical properties of the treated fabric are markedly different from those of the untreated fabric. Insights into zinc oxide encapsulated coated fabric prove their efficacy against microbes and hence can be used for medical apparel.

Highlights

Nanotechnology is basically the engineering of functional systems at the molecular scale
The design, characterization, production, and application of structures, devices, and systems are controlled by manipulation of size and shape at the nanometer scale which enhances their characters with at least one superior characteristic or property
The mechanism of destruction is very different from cations, which break the cell wall and membrane so that the walls fall apart, the cell collapses and its contents leak out, and the cell is no longer viable

Summary

Introduction

Nanotechnology is basically the engineering of functional systems at the molecular scale. The word nanotechnology is generally used when referring to materials with the size of 0.1 to 100 nano meters; it is inherent that these materials should display different properties from bulk (or micrometric and larger) materials as a result of their size These differences include physical strength, chemical reactivity, electrical conductance, magnetism, and optical effects [2]. Under suitable conditions various types of micro-organisms like bacteria, fungi and virus deposit themselves and multiply in contact with the human bodies These types of multiplication can cause staining, discoloration, degradation on the fabric surface and generates. Some type of finish is required to protect the textile surface from the growth of micro-organisms. If the nanoparticles are made small enough, the bacteria will internalize the nanoparticles, resulting in even higher killing efficiency as the cells are attacked from the inside too
