“…Zeolite particles, as potential material for textile surface modifications, are hydrated crystalline aluminosilicates consisting of three-dimensional frameworks of various numbers of SiO 4 and AlO 4 tetrahedra linked together in such a manner as to form channels and cavities within the size ranges 0.3-1.2 nm, filled by cations and water molecules [13]. Due to their particular characteristics, i.e., high thermal and hydrothermal stabilities, high surface area, exchangeable cations, and uniform internal channels and cavities, synthetic zeolites are exceedingly usable for numerous applications that are related to membrane separation, industrial ion exchange, adsorption, solid-acid catalysis processes, etc.…”

Abstract:The presented study focuses on the development of a pad-dry-thermofix functional coating process using a mixture of microporous aluminosilicate particles in diverse bath formulations to impart UV-ray-blocking, thermal stability and easy-care properties to the cotton fabric. The results of Scanning Electron Microscopy (SEM) and X-ray powder Diffraction (XRD) revealed the presence of three different types of zeolites within the examined sample, i.e., the largest amount being zeolite A, followed by the zeolite X, and the zeolite ZSM-5. The surface characterization results of zeolite-coated/cross-linked textiles provided evidence of acceptable UV-ray-blocking properties and increased thermal stability, as well as enhanced tensile strength and breaking tenacity without considerably decreasing the whiteness degree. Moreover, the dry crease recovery angle increased for the cotton fabric cross-linked via an mDMDHEU, and decreased significantly using 30 g/L zeolites negatively influencing qualitative values. TG/DTA results have proven the enlarged thermal stability of aluminosilicate-coated cotton, although combustion was not prevented.

“…However, the silver content and utilization of silver ions are generally low when cellulose is used without a reducing agent. Cellulose/Ag composites can be synthesized using Tollen's reagent (Montazer et al 2012). To extend this research, this paper reports on the use of other types of alkaline compounds to prepare cellulose/Ag nanocomposites; the silver content of nanocomposites was increased greatly under alkaline conditions.…”

A simple, environmentally friendly, and efficient synthesis method for cellulose/silver (Ag) nanocomposites was developed by microwave heating an alkaline aqueous solution of cellulose fiber and silver nitrate (AgNO3), which resulted in good utilization of silver ions and a product with high silver content. The effect of the alkaline compounds and reducing agents on the silver content and utilization rate of silver ions was investigated using atom absorption spectroscopy (AAS). The morphology, size, thermal stability, and surface components of cellulose/Ag nanocomposites were investigated using scanning electron microscopy (SEM), thermogravimetric analysis (TG), differential scanning calorimetry (DSC), and Raman spectroscopy. The alkaline compound and reducing agent influenced the size and shape of the silver nanoparticles. Reduced silver ions had the greatest influence on the surface components of cellulose; however, nano-silver particles exhibited no obvious influence on cellulose's thermal stability. Furthermore, cellulose/Ag nanocomposites exhibited excellent antibacterial activity against Escherichia coli and Staphylococcus aureus.

“…For instance, Khalil-Abad and Yazdanshenas produced superhydrophobic and antibacterial cotton fabrics using silver nanoparticles [1]. Along the same lines, Montazer and colleagues obtained antibacterial cotton fabrics through in situ synthesis of nano silver [2]. Jiang et al prepared the antibacterial cotton fabrics through in situ deposition of silver nanoparticles on the cotton fabrics by the reduction of Ag + without any reductant and dispersant [3].…”

In this study silver nanoparticles with different particle sizes and hence colors were synthesized on silk and cotton fabrics through reduction of silver nitrate. Particle sizes of the silver colloids were measured by dynamic light scattering (DLS). The structure and properties of the treated fabrics were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and UV-Vis reflectance spectroscopy. Various characteristics of the treated fabrics including antibacterial activities against a Gram positive (Staphylococcus aureus) and a Gram negative (Escherichia coli) bacteria, color effect, wash and light fastness, water absorption, fabric rigidity, and UV blocking properties were also assessed. The results indicated that the treated fabrics displayed different colors in the presence of silver nanoparticles with different particle sizes and exhibited good and durable fastness properties. Also, the size of the silver particles had a tangible effect on antibacterial activity of treated fabrics and its antibacterial performance was improved by decreasing the size of particles. Moreover, this process imparted significantly UV blocking activity to fabric samples.
