Enzymatic processing has been a suitable bio-based sustainable application for the textile industry, mitigates the use of harsh chemicals, and minimises environmental impact. Among these enzymes, cellulase enzymes have been extensively used for biopolishing applications. This study introduces an eco-friendly biopolishing of cotton fabric that has been developed by using enzymes extracted from wasted sugarcane bagasse waste in an aqueous medium. Various extraction conditions were explored, and experiments were conducted under diverse time, pH, and temperature settings. The qualitative BUTEXDCE2022C01 testing method was used to assess the biopolishing effects, resulting in a considerable reduction in fabric weight (up to 5.26%) and strength (up to 10.54%). The optimum biopolishing condition was identified to be 1 h at pH 4.8, 55 °C from the fermented solution on day three, indicating the presence of acid cellulase enzyme. The viability of cellulase enzymes has been verified through comparative analysis with commercial samples that had undergone enzyme-biopolishing. Extracted and filtered enzymes exhibited pH stability at room temperature and proved equally effective as industrial enzymes. As textile industries pursue eco-friendly solutions, extracting cellulase from wasted sugarcane bagasse could be a sustainable and alternative option, which also can be sourced locally. Therefore, these findings have wider implications for sustainable enzyme extraction methods and contributions to environmental conservation.
酶处理一直是纺织工业中一种合适的基于生物的可持续应用，它减少了苛刻化学品的使用，并将环境影响降至最低。在这些酶中，纤维素酶已被广泛用于生物抛光应用。本研究介绍了一种对棉织物进行生态友好型生物抛光的方法，该方法是通过在水介质中使用从废弃甘蔗渣中提取的酶来开发的。探索了各种提取条件，并在不同的时间、pH值和温度设置下进行了实验。使用定性的BUTEXDCE2022C01测试方法来评估生物抛光效果，结果织物重量显著降低（高达5.26%），强度也显著降低（高达10.54%）。确定最佳生物抛光条件为在第三天的发酵液中，于pH值4.8、55°C下处理1小时，这表明存在酸性纤维素酶。通过与经过酶生物抛光的商业样品进行比较分析，验证了纤维素酶的活性。提取并过滤后的酶在室温下表现出pH稳定性，并且证明与工业酶同样有效。随着纺织工业寻求环保解决方案，从废弃甘蔗渣中提取纤维素酶可能是一种可持续的替代选择，而且这种原料也可以在当地获取。因此，这些发现对可持续酶提取方法具有更广泛的意义，并对环境保护做出了贡献。
