The Impact

Natural dyestuff has reverted its position in the colouration of textile substrates due to rising concerns of consumers and buyers, particularly about environmental impacts and health issues. Eucalyptus leaves were selected in this study as a source of natural dye along with some of the most generally used mordants to observe the impact of dyeing on jute fabric while trying to keep the dyeing parameters at a minimum level. Dyes were extracted from eucalyptus leaves by boiling in water. Then, the fabric was pre-mordanted using different synthetic mordanting agents, such as alum, potassium dichromate, copper sulphate and ferrous sulphate, which are generally used to substantively enhance the dyestuff on textile fabrics and to improve the fastness properties. Synthetic mordant was used here instead of natural mordant due to the better dyeing compatibility of jute fabric with eucalyptus leaves, since natural mordant has little effect on jute fabric during the process of dyeing. Another aim of this research is to curb the time and energy consumption of the jute dyeing process and so the dyeing is carried out at 75 °C for about 30 minutes. Various types of evaluations were conducted through visual assessment, checking the colour-coordinate values and colour strength values. While colour fastness properties were evaluated by different fastness testing, such as colour fastness to water, washing, rubbing and perspiration. This dyeing process yields a colour range from yellowish to brown with the variation of mordants applied on the fabric. In addition to that, colour co-ordinate and colour strength values ensure better results of dyed fabrics pretreated with ferrous sulphate. Jute fabric dyed with only extracted eucalyptus solution provided satisfactory results in all colour fastness tests, while fabric treated with different mordants showed variations in fastness ratings, and fabric treated with ferrous sulphate and copper sulphate had slightly better fastness ratings.

Kepentingan meningkat untuk pewarna semulajadi bermula beberapa tahun lalu tetapi di pihak pengguna, manfaat tersebut hanya mula dirasai. Pewarna asli dianggap sebagai pewarna mampan dan mesra alam; mereka boleh menghasilkan warna yang berbeza warna dan mempunyai ketahanan luntur yang lebih rendah daripada pewarna sintetik. Oleh itu, kertas kerja ini dikaji pada sifat kubu daripada pewarna yang diekstrak daripada kacang belalang dan buah-buahan asam buah.Warna-warna ini dipetik menggunakan kaedah berair dan pelarut dan telah digunakan di dataran terluntur ditenun kapas dan sutera kain.Yang digunakan bagi pedas meningkatkan penembusan warna (pewarna) dan sampel dicelup telah tertakluk kepada ujian kubu (membasuh, menggosok, peluh & ujian cahaya). Perbandingan analisis kepada tahap pewarnaan telah direkodkan dan ujian kubu baik daripada analisis membuktikan bahawa; warna boleh digunakan sebagai pewarna pada kapas dan sutera kain.   An interest for natural dyes increased several years ago but on the part of the consumers, the benefits are just beginning to be felt. Natural dyes are considered as sustainable and ecofriendly dyes; they can produce different shades of colours and have lower colour fastness than synthetic dyes. Therefore, this paper researched on the fastness properties of colorant extracted from locust beans and tamarind fruits pods. The colours were extracted using aqueous and solvent methods and were applied on bleached plain weaved cotton and silk fabrics. The use of mordant increased the penetration of the colours (dyes) and the dyed samples were subjected to fastness test (washing, rubbing, perspiration & light test). Comparative analyses on the degree of staining were recorded and good fastness test from the analysis proved that; the colours can be used as dyes on cotton and silk fabrics.

Synthetic dyes release huge amount of waste and uniform colourants lead to health hazard. It also disturbing the ecobalance of the nature. Natural dyes are mostly derived from plants, invertebrates, or minerals. The most of the natural dyes are vegetable dyes from plant sources-roots, berries, bark, leaves, and wood—and other organic sources such as fungi and lichens. Natural dyes exhibit good biodegradability and are more compatible with the environment. In spite of their inferior fastness, natural dyes are more acceptable to environmentally conscious people around the world. The present study deals with the natural dyes extracted from Rubia Cordifloria. The extracted dye used to dye selected silk fabric and myrobalan mordant used for dye ability, fastness properties, absorbency test. Two shades with different concentration have been developed. Absorbency properties of the dyes extracted from madder and sinking test was determined. The colour fastness through washing and rubbing (Wet and Dry) was an excellent satisfaction in both different concentrations.

The worldwide demand of natural dyes is of great interest due to the increased public awareness about the atmospheric and environmental pollution caused by the commercially available synthetic dyes. Nepal being wealthy in flora, would be fine research laboratory land for the plant based natural dyes. Among most of the natural dyes, plant-based dyes/pigments have wide range of applications in fabric, food, drug coloring, therapeutic values and also in solar cells in presence of different mordants. The use of mordant is inevitable during natural dyeing process in order to improve the fastness properties on fabrics, foods and drugs by forming a co-ordination complex with dye. In this article, a short overview of plant based natural dyes extraction applications and their scope and limitations will be discussed with special reference to Nepal. In the present review, the green methods of dye extraction, and dyeing technologies will be discussed, and the research fields based on natural dyes will be explored. Some of the natural dyes has also shown the antimicrobial, antioxidant, antifungal properties and hence are also discussed with biomedical applications.

Dyeing and fastness properties of a series of 4-fluorosulfonylphenylazo-5-pyrazolone dyes on polyester were investigated in this study. The 4-nitrophenylazo-5-pyrazolone dyes were also synthesized to compare their dyeing and fastness properties on polyester with those of fluorosulfonyl-substituted analogues. The substantivity of 4-arylazo-5-pyrazolone derivatives containing a p-fluorosulfonyl group in the diazo component was lower than that of their nitro analogues which have a higher extinction coefficient and higher affinity because of the polar nitro group. They showed relatively hypsochromic color and lower chroma on polyester compared with their nitro analogues because of the relatively weaker electron-accepting power of the fluorosulfonyl group compared to the nitro group. Disperse dyeing of polyester with 4-fluorosulfonylphenylazo-5-pyrazolone disperse dyes achieved high color fastness and reduces the adverse environmental impact of the dyeing process by providing the option of performing alkali clearing instead of reductive clearing, which has high biological oxygen demand when discharged into the dyeing effluent and generates carcinogenic aromatic amines.

Purpose The present study aims to focus on the feasibility of using an aqueous extract from the fruit shell of Camellia oleifera Abel as a source of natural colourant in printing-paste preparation for pigment printing of cotton fabric. The effects of pre- and post-mordanting with three common metallic mordants, that is AlK(SO4)2, CuSO4 and FeSO4 on colour yield and colour fastness properties are also investigated. Design/methodology/approach The printing paste was prepared by mixing the concentrated Camellia oleifera Abel fruit shell extract solution with commercially available synthetic thickener and binder. The fabric sample was printed with the prepared printing paste using a flat-screen printing technique. To determine the effects of pre- and post-mordanting, AlK(SO4)2, CuSO4 and FeSO4 mordant aqueous solutions with various concentrations were applied using the pad-dry technique. Comparisons between printing with and without mordants were evaluated in terms of colour strength (K/S values) and colour fastness to washing, light, crocking and perspiration. Findings Without the mordants, the printed fabric had a yellowish brown shade with acceptable colour fastness properties, that is fair to good wash fastness, moderate light fastness, good to very good crocking fastness and fair to good perspiration fastness. The use of mordants, especially CuSO4 and FeSO4, not only enhanced colour strength but also imparted different colours to the fabric. Compared to the unmordanted fabrics, colour fastness properties were mostly comparable or improved in the mordanted fabrics depending on the type and concentration of mordants. Research limitations/implications Although in the case of CuSO4 the light fastness was increased to a good to very good level, it is recommended that the final print be produced with a concentration of less than 0.125 gL−1 to yield the print with the residual amount of Cu metal under the limit, that is less than 50 ppm as regulated by the Oeko-Tex® standard. Practical implications The obtained prints from Camellia oleifera Abel fruit shell extract provided shades with satisfactory colour fastness to washing, light, crocking and perspiration. The extract from Camellia oleifera Abel fruit shell has the potential to be used as an alternative to synthetic dye in the textile industry. Originality/value The use of Camellia oleifera Abel fruit shells, which are considered as abundant byproducts of tea seed oil production, as natural colouring agents for pigment printing of cotton fabric has been reported for the first time. It will minimise the environmental impact of this waste and create more valuable textile products.

Purpose This study aims to evaluate the dyeing of the p-aramid fibre with cationic dyes and investigate the effect of dyeing in the protection of the fibre from ultraviolet (UV) light. Design/methodology/approach P-aramid fabric has been dyed with cationic dyes using benzyl alcohol as swelling agent to promote the penetration of dye molecules into the fibre. The fabrics were evaluated against colour strength (K/S) value and colour fastness properties after dyed with cationic dyes using full factorial design. This design was used to study the effect of factors that affect the response variables as well as to study the interactions among the factors on response variable. The bursting strength, scanning electron microscopy analysis and X-ray diffraction analysis of undyed and dyed p-aramid fabric were performed before and after exposure to UV light to investigate the changes in mechanical behaviour. Findings The results show that the p-aramid fabric dyed with cationic dyes has good K/S values and good fastness properties. The exposure of undyed p-aramid fabric to UV light causes serious loss in strength over short duration i.e. 40 h. Dyeing of p-aramid fabric enhances the resistance to UV light which reduces the loss in strength. Originality/value Most of the work is patented and no one has done the process optimization for the industry, so this study offers promising outcomes concerning the dyeing of p-aramid fabric with enhanced shade depth and good colour fastness characteristics.
