Optimized Conditions

Standard procedures for mordant dyeing were used to dye plain weave cotton and silk fabrics with dye from four selected indigenous plants viz: A. coriaria, V. paradoxa, M. lucida and H. madagascarensis. Alum and ferrous sulphate mordants were with the following mordanting methods; pre, simultaneous and post mordanting. Color fastness was used as a basis to evaluate the performance of each method. Color strength imparted on fabric was used as a basis to optimize the following selected dyeing variables viz: temperature, dyeing time, material to liquor ratio (M:L), and mordant concentration (o.w.f). Mordant dyeing under optimized conditions improved color strengths and fastness on both cotton and silk fabrics. According to the optimized variables, silk fabrics required a little more heating (80˚C to 95˚C) for a longer time (≈ 1hr 30mins) than cotton to achieve optimal strengths of color. The fastness obtained for various fastness characteristics on both fabrics dyed under optimized conditions varied from fairly good (3) to excellent (5) with cotton giving better fastness. However, silk recorded better color strength in term of k/s values in the range of (110 to 260) and more lustrous appearance was observed on it. Dye from M. lucida plant species recorded overall superior color characteristics on both fabrics and with both mordants.

Natural dyes and eco-friendly finishing of textile fabrics is gaining popularity because of the consciousness of people in saving the ecology. Widely available resources in India have encouraged researchers in experimenting on extraction and application of dyes for textile colouration. The aim of the present experiment was to standardize a protocol for optimization of pre-treatment, mordanting and dyeing of cotton yarn with African marigold flower petals. Myrobolan, pomegranate rind and tamarind hull were utilized in different concentrations for pre-treatment. Effect of different mordants and pre-treatment concentrations on colour strength (K/S, L, a* and b*) parameters of the cotton yarn is was studied. Optimised pre-treatment concentrations, mordants and dyeing techniques on colour fastness parameters are also presented. Myrobolan followed by pomegranate rind pre-treatment produced darker and even shades on cotton yarns. Metallic salts viz., Stannous Chloride, Copper Sulphate and Ferrous Sulphate proved to produce shades with good to excellent colour fastness properties.

Purpose The purpose of this study is to identify the most influential factors affecting the printing properties and print quality of digitally printed silk fabrics in terms of colour strength and fixation percentage. Design/methodology/approach In this study, five factors (concentration of thickener, concentration of urea, concentration of alkali, pH of pretreatment liquor and steaming duration) were investigated using a blocked 25−1 fractional factorial experiment. The type of thickeners [polyacrylic acid and polyacrylamide (PAM)] were considered as a block. Findings Linear models were obtained and statistically tested using both analysis of variance and coefficient of determination (R2), and they were found to be accurate at 90 per cent confidence level. It was revealed that concentration of alkali, concentrations of urea and pH of the pretreatment liquor had an increasing effect on colour strength, whereas concentration of thickener and steaming duration showed decreasing effect on colour strength of digitally printed silk fabrics. Furthermore, concentration of alkali, concentrations of urea had increasing effect on dye fixation percentage, whereas steaming duration showed decreasing effect on dye fixation percentage of digitally printed silk fabrics. In addition, PAM thickener based pretreatment recipe exhibited better printing properties for the digitally printing of silk fabrics. Originality/value The main influences and significant two-factor interactions were discussed in detail to gain a better understanding of the printing properties of digitally printed silk fabrics. The findings of this study are useful for further optimisation of pre- and post-treatment processes for digital printing of silk fabrics.

Purpose This study aims to improve the natural dyeing recipe with better light fastness using ascorbic acid (vitamin C) with pulverised plant dyes. Design/methodology/approach Silk fabrics pre-mordanted with alum (aluminium ammonium sulphate) were dyed using six types of plant dyes available in Sarawak, Malaysia, namely, Engkerabai leaves (Psychotria viridiflora), Ketapang leaves (Terminalia catappa), mangrove bark (Ceriops tagal), Sepang wood (Caesalpinia sappan), mangosteen husk (Garcinia mangostana) and onion skin (Allium cepa). Then, the dyed samples were immersed in vitamin C. The dyed and vitamin C-treated silk samples were exposed to direct sunlight for 40 h to test whether vitamin C had any effect on the light fastness of the dyed samples. Findings It was found that the fabric samples using vitamin C for after-treatment, particularly Engkerabai, Ketapang, mangrove and mangosteen, exhibited better light fastness. The colours of the four samples changed and looked darker when compared to the non-treated fabric samples. However, it was observed that vitamin C had a reverse effect on Sepang wood and onion skin. The acidic aqueous solution of vitamin C discharged the dyed samples instead. Originality/value In conclusion, depending on the plant types, vitamin C can be used to improve the light fastness of natural dyes or as a reducing agent for natural dyes.
