Abstract

Polyester fabrics were dyed with prepared disperse dyes using the high temperature dyeing method. The dye exhaustion of the dye baths were compared to the low-temperature dyeing method in an attempt to study the proportion of the dye effluent solution that affects the environment. The dye uptake of the high temperature dyeing method (HT) of polyester fabric was compared with low temperature dyeing, hence (HT) increased the color strength of the investigated dyes by 309 and 265%. This means that the amount of dye present in the dye effluents by using the high-temperature dyeing method is almost non-existent, and this is reflected positively on the environment as these wastes pollute the environment. Post-treated polyester fabric was prepared through a two-step hot process after being immersed in a solution of Titanium (IV) oxide nanoparticle sizeTiO2 NPs (21 nm primary particle size) at 80 °C followed by curing at 140 °C. The treated fabric realized an optimum UV protection factor of 34.9 and 283.6 degrees. These fabrics also demonstrated a strong ability to improve the light fastness properties. Finally, the potential applications of such value-added fabrics as self-cleaning and antifungal activities were investigated. The results indicated that the treated dyed fabrics with TiO2 NPs endowed fabrics with the excellent self-cleaning of methylene blue dye. From the above, the treated fabrics with nano-titanium dioxide can be used in some promising fields, for example, medical ones.

Highlights

High temperature dyeing is the most extensive strategy for batch coloration, grants increased diffusion, and along these lines, the expanded rate of dyeing by lessening the union between the polymer chains increasing the kinetic energy of the dye molecules [1,2,3]

Summary

Introduction

High temperature dyeing is the most extensive strategy for batch coloration, grants increased diffusion, and along these lines, the expanded rate of dyeing by lessening the union between the polymer chains increasing the kinetic energy of the dye molecules [1,2,3]. Environmental problems are related to the dye baths utilized with a wide scope of various components added to the dye bath, regularly at high concentrations. Dyeing at 130 ◦ C makes swelling of the fiber even and dye molecules penetrate the fiber polymer more than that accomplished in the low temperature dyeing method at. Utilizing nanotechnology has upgraded the functions of material to multifunctional fabrics with antibacterial and UV protection properties and stain resistance have been reported [4,5,6,7,8,9].
