Biostoning using cellulase is a process used in place of the traditional stone‐washing of denim. This process guarantees a more controlled removal of the Indigo blue dye from the cotton fibers, giving an aged‐look and softness to denim. However, it also causes backstaining and generates a high volume of colored effluent. In this context, this work evaluated the possibility to reuse the effluent from the biostoning process combined with montmorillonite addition. It is an attractive and sustainable alternative to the conventional process.

蒙脱石在生物石化工艺中的利用作为废水回用的策略

使用纤维素酶进行生物染色是代替传统的牛仔布石洗工艺。此过程可确保从棉纤维中更好地控制靛蓝染料的去除,从而使牛仔布看起来既老化又柔软。但是,它也会造成后染并产生大量有色废水。在这种情况下,这项工作评估了将生物石化过程中的废水与蒙脱石相结合再利用的可能性。它是传统工艺的一种有吸引力且可持续的替代方法。
