Purpose

The study aims to test the color fastness of wool and linen fabrics dyed by simple immersion in ethanol dissolutions of fungal dyes.

Design/methodology/approach

Ethanol dissolutions of Talaromyces australis and Penicillium murcianum dyes were prepared to a concentration of 0.3% and used to dye wool and linen samples by immersion. Color fastness to washing, dry cleaning, wet and dry rubbing, perspiration and light, were tested according to AATCC standards.

Findings

Color fastness reached acceptable results at dry cleaning and wet and dry rubbing by crocking but did not performed well at laundering, perspiration and light exposure. Results indicate that ethanol dissolutions of tested dyes had better affinity for wool fabrics than linen, but the dyeing method requires further improvements to be considered attractive for full scale applications.

Originality/value

In this work sustainability of fabrics dyeing is improved by using natural pigments produced by filamentous fungi and a method to dye that requires no increment of temperature and mordants.

真菌染料染色后织物的色牢度

目的

该研究旨在测试简单浸入真菌染料在乙醇中溶解后染色的羊毛和亚麻织物的色牢度。

设计/方法/方法

制备了Talaromyces australismuricnum murcianum染料的乙醇溶出度为0.3%的浓度,并用于通过浸入对羊毛和亚麻样品进行染色。根据AATCC标准测试了耐洗,耐干洗,湿和干摩擦,耐汗和耐光的色牢度。

发现

耐洗牢度在干洗,湿擦和干擦摩擦下均达到可接受的结果,但在洗涤,汗渍和光线照射下表现不佳。结果表明,经测试的染料在乙醇中的溶解度比亚麻对羊毛织物的亲和性更好,但是染色方法需要进一步的改进才能被认为对全面应用具有吸引力。

创意/价值

在这项工作中,通过使用丝状真菌产生的天然颜料和不需要增加温度和媒染剂的染色方法,可以改善织物染色的可持续性。
