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.

Highlights

Increasing requests for functional, comfortable and safe fiber-forming materials, as well as major global competition in this field, prescribe the intensive development of new technologies for the processing of high added-value textiles, and the progress of innovative, but low-cost and environmentally friendly procedures for their finishing
The industrially synthesized aluminosilicate particles in aqueous finishing formulations by varied varied pHs, and a commercially available mDMDHEU as a crosslinking agent were pHs, and a commercially available mDMDHEU as a crosslinking agent were selected selected for the functionalization of cotton fabric using a conventional pad-dry-thermofix procedure
From the Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray powder Diffraction (XRD) analyses of aluminosilicate particles, it could be concluded that the SEM, FTIR and XRD analyses of aluminosilicate particles, it could be concluded that the examined examined samples were composed of the cubic crystals of zeolite A, the octahedral crystals of zeolite samples were composed of the cubic crystals of zeolite A, the octahedral crystals of zeolite X, and the

Summary

Introduction

Increasing requests for functional, comfortable and safe fiber-forming materials, as well as major global competition in this field, prescribe the intensive development of new technologies for the processing of high added-value textiles, and the progress of innovative, but low-cost and environmentally friendly procedures for their finishing. The use of natural cellulose-based materials has recently become of great interest for numerous new fields of application (protective clothing, clothing for medical and sport activities, interior decorative coverings, technical textiles, etc.), due to the fact that they are readily available in large quantities and produced, and because their molecular structures offer excellent potential as a matrix for the design of bioactive, biocompatible, and intelligent materials [2,3]. Numerous techniques are presently being employed for changing the materials’ surface morphologies and, consecutively, their properties, i.e., dip-coating by the dispersion of well-defined nano-oxides [4,5,6], chemical grafting of particles [7], functionalization by inorganic sol-gel coating [8], layer by layer deposition method [9,10], and embedding the (nano)particles on the Polymers 2018, 10, 57; doi:10.3390/polym10010057 www.mdpi.com/journal/polymers
