Utilization of Juglans Regia l. (fruit hull) and Salix Alba l. (wood ash) for Textile Applications

Mr. Syed Maqbool Geelani

The importance of colour in textiles has been recognized before thousands of years. Natural dyes, dyestuffs and dyeing are as old as textiles themselves. Environmental problems from the dyeing of textiles arose after industrialization, when traditional natural dyes were replaced by synthetic dyes. Synthetic dyes are designed to resist chemicals, and improve the quality of the product but are persistent in the environment. Synthetic dyes are produced from cheap petroleum sources and generally have easy dyeing, superior fastness properties, widely available at an economical price and produce a wide variety of colours and shades. The chemicals used to produce synthetic dyes are highly toxic, carcinogenic, allergic, explosive and dangerous to work with. The production of synthetic dyes involves many violent reactions, which are considered health hazardous. As a result of the worldwide concern over the carcinogenic effects, toxicity and allergic reactions associated with synthetic dyes interest in the revival of natural dyes in textile colouration is increasing. The experiment was laid with an aim to extract natural dye from Juglans regia L. (fruit hull) and mordant from Salix alba L. (wood ash). The extracted dye and mordant was tested on wool and cotton fabric. The dyeing of the fabrics was done in presence and absence of the mordant. The mordanting was performed by adopting pre, simultaneous and post mordanting methods. The extraction and application of the dye and mordant was performed without the usage of any chemical agent. The dye was extracted by soxhlet apparatus using distilled water as solvent. Whereas, solution of mordant was prepared by soaking the material in distilled water. The dyed fabrics were evaluated in terms of percent absorption, Colour coordinates (L*, a*, b*, C, hO, ΔE), Colour strength (K/S), Relative colour strength (K/S) and retention tests in terms of washing, rubbing and light were performed. The results of the dyed fabrics showed beautiful colours of light and dark brownish shades in wool fabric. However, cotton fabric produced pale dull yellowish shades. The colour quality of the wool fabric in all the tests performed recorded significant results and grades of retention were also acceptable which recorded Excellent (5), good to excellent (4/5) and good (4) grades when evaluated with reference to the grey scale. The cotton fabric does not showed much affinity for the dye and mordant and recorded low values. The results of the work done suggest Juglans regia L. (fruit hull) and Salix alba L. (wood ash) as an potential dyeing materials for wool fabric. The extracted dye and mordant can also be utilized for the dyeing of other fabrics. The potential of the substrates can be utilized in textile industries which can flourish both at national and international market. Key words: Juglans regia L., Salix alba L., Wool, Cotton, Textiles.
