Dyeing Method

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.

Polyester fabric is usually dyed with disperse dyes which has severe limitations specially toxicity and environmental issues. The aim of the present research is to introduce an ecofriendly dyeing process for polyester fabric with natural dyes. The natural colorants were extracted from mahogany seed pods using the simple acid boiling method. The spectroscopic analysis of the crude extract was carried out by UV and IR spectra of the extracted dyes and illuminated the presence of natural tannins as coloring materials in the crude extract. 10g fabric was dyed in 200cc extracted solution at 130⁰C for 60 minutes in exhaust dyeing method followed by neutralization and soaping. Finally, a light brown dyed fabric was obtained. The dyed fabric exhibited color strength in terms of k/s value of 0.63 (λmax 360nm), lightness of 80.565 and chromaticity value of 12.002 CIE units. Different samples were dyed by fluctuating the dyeing period. The dyeing traits of the dyed materials were judged in terms of their color strength and fatness properties. All testes were carried out following the ISO standards. From the results, it is lucid that the dyed fabric showed acceptable color fastness properties in case of all fastness except color fastness to light. It is observed that dyeing time had profound influence on the color strength (k/s value) of the dyed material. The k/s value increases with the increase of dyeing period up to 120 minutes. The maximum color strength (0.76) was noted for the fabric. The shorter dyeing time produces lighter samples and the longer dyeing time produced colorful samples.

The textile sector is closely linked to environmental pollution as a result of the use of toxic chemicals and their disposal in liquid waste, which negatively affects for the environment. Moreover, textile industries, especially wet processing, consume a large amount of energy, water, and chemical auxiliaries. Therefore, there is an urgent need to find a solution that takes the problem of environmental pollution into account. Considering ultrasound as an environmentally safe alternative for dyeing polyester fabrics with the disperse dyes that we have prepared before, the comparison between the ultrasonic dyeing method and conventional dyeing at low temperatures was investigated. Dye exhaustion on polyester fabrics and fastness properties such as the washing, rubbing, light, and perspiration of all of the dyed fabrics were performed by two dyeing methods. Additionally, the ultraviolet protection factors (UPF) for dyed polyester fabrics were evaluated.

The dyeing properties of ethylated Chinese fir powder with disperse dyes under high temperature and high pressure were investigated in this paper, the dyeing results indicated that the color shade of dyed ethylated fir is similar to that of dyed polyester fabric while PH value of dyeing solution is between 4~5, and the dyed sample is of a good wash fastness. At the same time, the characteristics of the samples were analyzed by FT-IR and SEM, it indicated that dyes molecules were adsorbed on the surface and went into the microporous of ethylated fir powder, so that brighter color were observed due to the fact that the ethylated fir powder leads to a smooth surface which being favorable for the reflection of light.

Purpose The purpose of this paper is to prepare new disperse dyes and apply for dying polyester fabrics. Design/methodology/approach The synthetic reaction was carried out through two steps: preparation of arylhydrazones and alkylation using enaminone and dimethylaminovinyl-pyridazine. The high temperature method was used to apply these dyes to polyester fibres. Findings The study revealed that there is a significant effect of the new prepared disperse dyes on polyester fabrics. The structures of the prepared dyes were established based on elemental analysis and spectral data (infra red (IR), mass spectrometry (MS) and proton nuclear magnetic resonance (1H-NMR), carbon 13th nuclear magnetic resonance (13C-NMR)). Research limitations/implications Disperse dyes containing heterocyclic moiety have attracted great academic and industrial attention owing to their significant. The potential of using disperse dyes easily prepared from arylhydrazones are promise broad applications for these dyes. Practical implications The presence of N-thienyl and N-pyridazinyl in the structure of the synthesised disperse dyes would be expected to add the bioactivity advantage. Also, it can be used in formulating the antimicrobial fabrics. Social implications The N-thienyl and N-pyrdiazinyl derivatives of azo dyes are expected to be superior to in the application for fabrics. It may be useful for other applications like painting. Originality/value This paper helps to synthesise novel thiophene or pyridazine-based dyestuff for application in dying properties on polyester fabric and study their fastness properties.

The present study aims to evaluate the application of coumarin as a green carrier alternative for dyeing of polyester fabrics, as well as to optimize key dyeing parameters in order to obtain greater color strength (K/S) at lower temperatures than 130°C using single azo class dispersed dye. For this purpose, a full-factorial design was used to study the influence of the single and interactive effects of four factors involved in the dyeing process, namely, pH, temperature, and coumarin and dye concentrations. The chosen technique was a 24-factorial, one-center point, and three replicates at the center point resulting on a response surface, which has shown an increase of the color strength of five times at 90°C, and of three times at 100°C when compared to dyeing at the same temperatures without the use of a carrier. In addition, excellent fastness to washing and to rubbing were obtained.

Novel bisazo-bisazomethine disperse dyes were prepared by the coupling of diazotized solutions of various aromatic amines with 2,2'-{sulfonylbis [4,1-phenylene nitrilomethylylidene]} diphenol (SB). Above Schiff base was prepared by the condensation of 2-hydroxybenzaldehyde with 4,4’-sulphonyl- dianiline (Dapson). The resultant dyes were characterized by elemental analysis, IR and1H NMR spectral studies. The UV Visible absorption spectral data were investigated in dimethylformamide (DMF) and are discussed in terms of structural property relationship. Their dyeing performance as disperse dyes has been assessed on polyester fabrics. The results show that a better hue was obtained on polyester fabrics and have mild to moderate fastness properties.

This research studied the finishing process of nano TiO2 on PET fabric by thermal treatment. The effect of different curing temperatures of nano TiO2 treatment on yellowness, hydrophilicity, self-cleaning of red wine stains and disperse dyeing properties of PET fabric was investigated. The results show that curing of nano TiO2 on the PET fabric should be done at the temperature not less than 180°C. With nano TiO2 treatment, the hydrophilicity and self-cleaning properties of PET fabric were increased. The effect of nano TiO2 treatment on the dyeing properties of three disperse dyes, viz. C.I. Disperse Red 60, C.I. Disperse Violet 33 and C.I. Disperse Red 167, was examined. Nano TiO2 treatment influenced on the color strength of each dyes in a different way.
