Abstract Multifunctional cellulosic fibers are in high demand for use a variety of applications. Functional obtained through green and sustainable approaches getting special attention because the need to limit environmental impact hazardous chemicals. Herein, novel facile, efficient, eco-friendly approach multifunctional viscose fibers@Ag NPs (VF-Ag) was designed by rapid, one-pot biosynthesis route using guava leaf extract as reducing stabilizing agent. UV–Vis, TEM, SEM, EDX, FTIR, XPS were...
A novel approach toward the production of multifunctional printed technical textiles is reported. Three different metal oxides nanoparticles including titanium dioxide, magnesium oxide, and zinc oxide were prepared characterized. Both natural wool synthetic acrylic fibers pretreated with followed by printing using polylactic acid based paste containing or basic dyestuffs. Another route was applied via post-treatment targeted fabrics after running process. The color strength (K/S)...
Abstract A systematic study is currently demonstrated approach for approving the superior role of silver and palladium metallic particles in acting mordant with acquiring dyed cotton fabrics excellence color fastness additional functions antimicrobial potentiality UV-protection action. Whereas, samples were extract red peanuts skin as natural textile colorant (RPN dye). The represented data revealed that, absence mordant, treated metal precursors prior to dyeing exhibited excellent strength,...
Abstract The dissolution rate of hydrophobic dyes like Vat Red 13 poses a significant challenge in dyeing processes due to their poor solubility aqueous media. This study explores the formation and characterization an inclusion complex between (VR13) β-cyclodextrin (β-CD) enhance its rate. solid is prepared using two distinct techniques: physical mixture, encapsulation by adopting molar ratio 1:1. enhancement liquid state was examined UV-Vis absorption spectrum values. characterized...
In this work a Disperse red 60 and blue 56 were converted to the nano scale using ultrasonic homogenizer characterized by transmission electron microscopy. Dyeing of polyester fabrics was carried out in temperature range 70–100º C compared with dyed same dyes without sonication. two different carriers: salicylic acid HC carrier. ZnO powder used improve light fastness for fabrics. Keywords: Dyes, Light Fastness Nano Powder, Nanotechnology, Polyester Fabric
The development of multifunctional fabrics is an important purpose for their application in many fields. This study provided a simple approach innovative textile design by applying the optical properties Plasmonic noble metal nanoparticles. utilization feasible technique to functionalize both semi-synthetic and synthetic namely viscose acrylic fabric has been accomplished. Where, functions have developed situ synthesis silver nanoparticles (Ag NPs) into surface using trisodium citrate as...
Thickeners have been used as a significant component in textile printing pastes. They are characterized with high molecular weight, viscosity an aqueous medium, good storage, long hydration time consistent other paste components and being colorless. impart plasticity stickiness to the print ability introduce designs without bleeding. The major function of pastes is hold, adhere transfer dyestuff onto targeted fabric. There various well known synthetic natural thickeners.
The environmental constrains issued recently in many countries reinforce the textile chemists and colorists to adopt eco-friendlier methods during dyeing finishing of substrates. Herein, a genuine colorant extracted from mulberry leaves was used natural silk fabric using conventional heating as well ultrasonic- or microwave-assisted dyeing.Adopting pre-, meta-, post-mordanting methods, carried out also presence iron II sulphate heptahydrate mordant. colour strength, colorimetric data,...
Abstract Progressive environmental awareness and legislation regarding the pollutants discharged from textile coloration plants allocate natural colorants in forefront position for dyeing printing of many substrates. In this study, a genuine dye was synthesized by combining diazonium salt m -anisidine with crude extract peanut skin. The melting point (SD) as well its Fourier transform infrared UV–Visible spectra recorded. SD used wool, cotton, Lyocell®, polyester fabrics different shades,...
A very promising green chemistry concept that should gain more traction is the introduction of semiprepared azo dyes, which are made by modifying natural extracts with group. This would reduce dependency on toxic and nonbiodegradable synthetic dyes while also giving economic value to agricultural wastes. In current study, an extract peanut red skin was used as agro-waste a source polyphenols prepare dye coupling it diazonium salt ρ-nitroaniline. Then, prepared improve functional properties...
