Extremozymes as Future Appropriate Benign Elements for Eco-friendly Wet Processing of Wool and Silk

ABSTRACT

Wool and silk are the most common protein fibers in the textile and clothing fields. They pass through many preparative and finishing wet processing, which are extensive energy and water-consuming operations. Any technique or tool which may share in reduction of energy and water consumption during wet processing is a subject of highest priority for industrialists, technologists, and economists related to the field. This article review discusses the feasibility of using the extremozymes as possible future elements in saving energy and water consumption during textile wet processing. The extremozymes, viz. thermophilic and basophilic enzymes, would enable the textile chemists and colorists to combine two wet processes in one bath, and hence, the consumption of water and energy could be minimized. Various classes of extremozymes, namely proteases, lipases, cellulases, pectinases, and xylanases, are appropriate candidate for some wet processes of natural protein fibers. These include carbonization, scouring, bleaching, dyeing, shrink-proofing, and anti-pilling of wool as well as degumming of natural silk.

摘要

羊毛和丝绸是纺织和服装领域最常见的蛋白质纤维. 它们经过许多制备和精加工工序, 这是一项消耗大量能源和水的操作. 在湿法加工过程中, 任何可能有助于减少能源和水消耗的技术或工具都是与该领域相关的工业家、技术专家和经济学家最优先考虑的主题. 本文综述了在纺织湿加工过程中, 利用极端酶作为未来可能的节能节水元件的可行性. 极端酶; 维兹嗜热和嗜碱性酶将使纺织化学家和着色剂能够在一个浴中结合两种湿法工艺, 从而将水和能源的消耗降至最低. 各类极端酶; 也就是说, 蛋白酶、脂肪酶、纤维素酶、果胶酶和木聚糖酶是天然蛋白纤维某些湿法加工的合适候选酶. 其中包括羊毛的碳化、煮练、漂白、染色、防缩、防毛以及天然丝绸的脱胶.
