Abstract

Coloured textile products are more marketable, and are therefore always in higher demand. This has increased the use of synthetic dyes in the textile industry, thus raising environmental pollution associated with synthetic dyes. Natural dyes have been shown to be suitable alternatives. However, the use of metallic mordants during dyeing means the process is not eco-friendly, hence the need to develop bio-mordants that can be used as alternatives to some toxic metallic mordants. In this study, the effects of bio-mordants on the dyeing properties of Euclea divinorum Hiern (Ebenaceae) dye extract were assessed using different mordanting methods on cotton fabric. Dyeing characteristics were evaluated in terms of colour fastness and colour strength. Antioxidant textile finishing properties of the natural dye on cotton fabric was determined using the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) method. The bio-mordants improved the colour strength for dyed cotton fabric from 0.612 to 0.863 and 0.911 for the cotton fabric mordanted with mango and rosemary, respectively. This study identified an important basis of suitable bio-mordants that can be applicable when dyeing cotton fabric with E. divinorum natural dye. In addition, the good antioxidant activity of 72.5% indicates that E. divinorum dye extract is a promising agent for the future development of bioactive, protective and health textile fabric.
利用生物防霉剂提取二维果染料清洁生产生物活性彩色棉织物
彩色纺织品的销路更好,因此需求量也大。这增加了纺织工业中合成染料的使用,从而增加了与合成染料有关的环境污染。天然染料已被证明是合适的替代品。然而,在染色过程中使用金属媒染剂意味着该过程不环保,因此需要开发可作为某些有毒金属媒染剂的替代品的生物媒染剂。采用不同的媒染剂对棉织物进行媒染剂染色,研究了生物媒染剂对桉树染料浸出物染色性能的影响。从色牢度和色强度两方面评价了染色特性。采用2,2-二苯基-1-吡啶酰肼自由基(DPPH)法测定了天然染料在棉织物上的抗氧化整理性能。生物媒染剂对染色棉织物的色强分别由0.612提高到0.863,对芒果和迷迭香媒染剂的棉织物的色强分别提高到0.911。本研究为棉织物天然染料染色确定合适的生物媒染剂提供了重要依据。此外,其抗氧化活性达72.5%,预示着枫香染料提取物在未来开发具有生物活性、防护性和保健性的纺织织物方面具有广阔的应用前景。
