A novel blue azo-anthraquinone reactive dye was evaluated in the dyeing of cotton by using a dip–pad–steam process. Dyeing method and properties were examined in detail and the results showed that the dyeing method consisting of dye concentration of 25 g/L, sodium carbonate of 12 g/L, dipping time of 3 min and steaming time of 30 min was the most effective when a conventional “one-dip–one-nip” process was used. The fixation of the dyes on cotton could reach up to 93.4%, the wash and rub fastness both reached grade 4 above, and the light fastness reached grade 4–5 above. Such colored cotton showed very close colorimetric properties.

Biopolymers are suitable replacement materials for different chemical processes. In this work, silk yarns were treated with different chitosan concentration and then dyed with mono and bi-functional reactive dyes. The color yield, color difference and color fastness to light and washing of the dyed silk yarns were evaluated. Also, the effects of chitosan concentration, type of the reactive dyes on dye uptake of samples were studied. The bi-functional reactive dye has a high adsorption compared to mono-functional ones. The silk yarn treated with 3% chitosan had higher K/S values, washing and light fastness. The effects of chitosan on the antibacterial properties of silk yarns against two kinds of bacteria: Staphylococcus aureus and Escherichia coli were investigated. The treated silk samples were found to have antibacterial potential due to the antibacterial property of chitosan. Scanning electron microscopy (SEM) photographs reveal the deposition of chitosan on the treated yarns. Washing durability, handle properties, and yellowness of treated and dyed samples were also investigated.


Cotton leaves have been used to extract natural dye for dyeing of Egyptian cotton variety Giza 86 fabric and its blend with polyester 50:50, using different mordants such as iron (II) sulfate, copper (II) sulfate, and alum. The exhaust dyeing method was utilized using the pre-mordant technique. It is observed that both fabric samples can be dyed in different colors and depth of shades with Cotton leaves dye. Iron (II) sulfate ensures the best light fastness. Improved light fastness is obtained using abovementioned lower amounts of iron (II) sulfate and copper (II) sulfate. Alum is found to be less effective than iron (II) sulfate and copper (II) sulfate on the light fastness. As a novel alternative and potential natural dye, Cotton leaves extract solution can be used to get various colors and shades with satisfactory fastness properties. The mordanted and un-mordanted fabric samples were tested for their dyeing performance in terms of color parameters K/S, (L*), a*, b*, (C*) and (H*), and fastness properties (wash, perspiration, light and rubbing fastness) were studied. The samples showed high color strength, and high fastness properties. These results are very important for industrial application and with the production of a natural dye as an inexpensive source from cotton leaves as a by-product. Another objective is to increase the production of eco-textile garments with a good price for the Egyptian customers.

Cotton fabric was dyed with Liyuan Blue FL-RN reactive dye. The dye exhaustion and fixation percentages were calculated for all light, medium and dark shades. The dye shows very good exhaustion and fixation properties. Dyed samples were tested for light fastness property as per international standards. The results indicates the dye has a good light fastness property. The effect of UV absorber was studied in order to improve light fastness property. Cationic UV absorber CANFIX SUN was applied on the dyed cotton fabric by exhaust method. The results show that the color depth was similar after UV absorber treatment. In all the cases the use of UV absorber improved the light fastness of dyed fabrics as compared to untreated dyed samples.

The natural vegetable dye grape seed extract (GSE) was applied on the direct dyeing of lyocell knitted fabric. By changing the dyeing condition, the modified process was derived after evaluating various fastnesses of the dyed fabric. The direct dyeing method should be under the condition of GSE’s concentration 5g/L, bath preparation temperature 80°C, pH value 3, bath ratio 1:30, dyeing time 60min. The color is very sensitive to pH and GSE’s concentration. The rubbing fastness, washing fastness and light fastness is good, the acid perspiration fastness is better than the alkaline perspiration fastness.

The color which is obtained from the leaves of Henna, that is, Lawsonia inermis L., is used frequently in hair coloring. It is the chemical lawsone that is responsible for the reddish brown color. Its content makes it a substantive dye for dyeing the textile materials. This work concerns with the extraction and purification of natural dyestuff from a plant Lawsonia inermis L. and dyeing of cotton and silk fabric in exhaust dyeing method. The dye portion is isolated from the total extract by column chromatography and is evaluated by dyeing cotton and silk under different dyeing conditions. The color strength and fastness properties of the dye are undertaken by changing mordant and techniques of mordanting. The changes of colors have been noticed by using different types of mordant. The dye exhaustion percentage, wash, rubbing, and light fastness results reveal that the extract of henna can be used for coloration of cotton and silk fabric.

The present study was undertaken to use flour of wild taro (ColocasiaEsculenta (L.) Schott) as a resist printing paste for silk fabric and using reactive dye as a dyestuffs. The K/S values, whiteness index and sharpness of printed silk fabric were studied. The washing, water, perspiration, light and rubbing fastness of the printed fabric was also evaluated. From the present work it can be concluded that the pattern at resist printing area of silk fabrics show sharpness and whiteness. Colour fastness to water and perspiration were ranging between poor to fair level. Printed fabric exhibited fair to good level in washing, rubbing and light fastness. The advantages of this product are environmental friendly that is non-toxic fumes; production cost is lower, instance application and creative process enhancement in textile production.

Eco-friendly textile dyeing with natural dye is a global soaring interest for avoiding environment pollution incurred by synthetic dyes. This study attempts to compare the dyeing properties of cotton knitted fabric dyed with banana floral stem (BFS) sap and reactive dye. Natural dye i.e. BFS sap was extracted from the species of Musa sapientum by roller squeezer machine. The recipe of reactive dyeing was selected to match the exact shade with the natural dyed specimens. Conformation of the dye molecule fixation onto fiber surface was assured by FTIR-ATR spectra. Comparative analysis were carried out in response of degree of color levelness, color fastness to water, washing, perspiration, rubbing, light and effluent qualities. The economic viability of natural dyeing was also estimated. The specimens dyed with BFS sap have excellent color levelness and color durability characteristic alike reactive dye except light fastness properties. Moreover, natural dyeing costs were almost half of the reactive dyeing. Finally, this inquiry forecasts a less time, energy and water consuming, economical and ecofriendly dyeing process which could be deployed as replacement of reactive dyes with a few compromises.

Purpose The purpose of this study is to investigate the possibility of dyeing polyester (PET) fabric with natural dye extracted from annatto seeds using high temperature dyeing method. Design/methodology/approach PET fabric was dyed with annatto extract by varying dyeing parameters (temperature, time, pH and dye concentration) to determine the optimum dyeing conditions. The influences of KAl(SO4)2, FeSO4, gallnut mordants or a commercial UV absorber on colour yield and fastness properties were further studied. Findings Optimum results were obtained when the fabric was dyed at 130°C for 30 min in a dyebath containing 15 per cent (owf) annatto dye at pH 6. The dyed fabric had an orange shade and exhibited good to excellent wash, crock, perspiration fastness and fair light fastness. Further dyeing with mordants or UV absorber mostly resulted in lower colour yield and similar fastness properties. Research limitations/implications Although the light fastness was slightly improved to moderate level for the sample with UV absorber, a noticeable colour staining on cotton portion of multi-fibre fabric occurred when subjected to standard washing test. Compared to C.I. Disperse Orange 73, the annatto dye exhibited comparable colour fastness but had inferior light fastness when dyed at approximately the same colour strength. Originality/value Natural colourants from annatto seeds can be used to dye PET fabric at high temperature without mordants, yielding deep orange shade and satisfactory fastness properties. This study provides a promising application to reduce the environmental impact of synthetic dyes.

The natural dyes are used since pre-historic times for colouring the wide varieties of fibres for providing value addition, look and desire of the customer. In this study among the different sources of Lichen, Evernia cirrhatum was used to standardise the dyeing recipe for degummed silk cloth. A series of experiments were conducted to optimize the dyeing variables viz., medium of dye extraction, concentration of dye material, dye extraction time and dyeing time. The dyed fabric was then treated with chemical auxiliaries and fastness test was undertaken. Aqueous medium was used by taking 2 g of E. cirrhatum dye per 100 ml of water with 60 minute extraction time and 60 minute dyeing time was found to be optimum. In case of chemical auxiliaries, 2% of citric acid, 2% of sodium sulphate, 3% of oxalic acid and 4% tartaric acid with simultaneous dyeing method was found as best. It was observed that the dyed silk exhibited good to excellent colour fastness to washing and perspiration, no stain on rubbing and very good for light fastness. The chemical auxiliaries that exhibit best fastness characteristic were sodium sulphate and tartaric acid with fastness grade of good to excellent for washing and perspiration fastness, slight stain to no stain for rubbing fastness and good to very good for light fastness.
