未经处理的棉花含有大约90%的纤维素和各种非纤维素杂质，如蜡、果胶、蛋白质和脂肪。为了去除这些疏水性的非纤维素物质并生产出可以均匀染色和整理的高吸收性纤维，原棉传统上用相对苛刻且对环境不友好的化学品进行处理。利用高度特异性的酶而不是传统的有机/无机化学品的新生物制备工艺在纺织工业中越来越受欢迎。这种新技术的主要缺点是处理时间比传统方法长得多。这种局限性通过使用超声波能量与酶处理相结合来克服。原棉的组合酶/超声波生物制备提供了显著的优点，例如昂贵的酶的消耗少，处理时间短，处理的均匀性更好，并且所得纺织废水的量和毒性显著降低。(C)2004 Elsevier B. V.保留所有权利。
Raw unsecured cotton contains similar to90% cellulose and various noncellulosic impurities such as waxes, pectins, proteins, and fats. To remove these hydrophobic noncellulosics and produce a highly absorbent fiber that can be dyed and finished uniformly, the greige cotton is traditionally processed with relatively harsh and environmentally unfriendly chemicals. New bio-preparation processes that utilize highly specific enzymes instead of conventional organic/inorganic chemicals are becoming increasingly popular in the textile industry. The major shortcoming of this new technology is that the processing time is much longer than the conventional method. This limitation was overcome by use of ultrasound energy in combination with enzyme processing. The combined enzyme/ultrasound bio-preparation of greige cotton offers significant advantages such as less consumption of expensive enzymes, shorter processing time, better uniformity of treatment and a notable decrease in the amount and toxicity of the resulting textile wastewater effluents.
