The conventional scouring process involving the harsh environment is slowly being replaced with environment friendly approach using enzymes. These enzymes remove the non cellulosic impurities present in the fabric. Such a process would enhance the absorbency of the fabric without appreciable strength loss and also would help in the proper dyeing and finishing of the fabric. In the present work pectinase enzyme was isolated from Fusariumn sp. and was optimized under different cultural conditions. The partially purified pectinase enzyme was used in the scouring of cotton fabric. The efficiency of the bioscoured cotton fabric was compared with that of the conventionally scoured fabric. It was found that the water absorbing character of the bioscoured fabric was found to be considerably higher than that of the conventionally scoured fabric. Also, the tensile strength of the cotton fabric was found to be higher for the sample treated using pectinase enzyme than the sample treated conventionally. The results of FTIR confer that the pectin and wax impurities were removed from the cotton surface in both the conventionally scoured and bioscoured fabrics.
涉及恶劣环境的传统精练工艺正逐渐被使用酶的环保方法所取代。这些酶能去除织物中存在的非纤维素杂质。这样的工艺将提高织物的吸水性，而不会有明显的强度损失，并且有助于织物的适当染色和后整理。在目前的工作中，从镰刀菌属中分离出果胶酶，并在不同的培养条件下进行优化。部分纯化的果胶酶用于棉织物的精练。将生物精练棉织物的效果与传统精练织物的效果进行比较。结果发现，生物精练织物的吸水性能明显高于传统精练织物。此外，发现使用果胶酶处理的棉织物样品的拉伸强度高于传统处理的样品。傅里叶变换红外光谱（FTIR）的结果表明，在传统精练和生物精练的织物中，果胶和蜡质杂质均从棉表面被去除。
