鉴定具有低环境影响潜力的有效天然染料已成为纺织工业最近关注的焦点。从裂裂真菌中提取的色素曾被用作纺织品染料；然而，它们的使用需要大量的有机溶剂，对人体健康有影响。本研究探讨了以亚麻籽油为载体制备纺织染料银柳色素的可能性。有色亚麻籽油能有效地染色各种织物，天然纤维的着色效果更好。扫描电子显微镜（SEM）显示织物表面有一层色素膜。虽然机械测试显示经过处理的织物没有强度损失，但色牢度测试显示，洗涤和漂白剂对不同织物颜色的影响不同，颜色变化很大。扫描电镜研究证实了色素油层损失的差异，并显示了不同织物品种之间色素晶体形成的差异。研究发现，对染色油层加热后，织物表面会变得明亮、有光泽，这可能是天然防风雨服装的潜力。
Identification of effective natural dyes with the potential for low environmental impact has been a recent focus of the textile industry. Pigments derived from spalting fungi have previously shown promise as textile dyes; however, their use has required numerous organic solvents with human health implications. This research explored the possibility of using linseed oil as a carrier for the pigment fromScytalidium cuboideumas a textile dye. Colored linseed oil effectively dyed a range of fabrics, with natural fibers showing better coloration. Scanning electron microscopy (SEM) revealed a pigment film over the fabric surface. While mechanical testing showed no strength loss in treated fabric, colorfastness tests showed significant changes in color in response to laundering and bleach exposure with variable effects across fabric varieties. SEM investigation confirmed differences in pigmented oil layer loss and showed variation in pigment crystal formation between fabric varieties. Heating of the pigmented oil layer was found to result in a bright, shiny fabric surface, which may have potential for naturally weatherproof garments.
