Bast fibers, such as ramie, hemp, flax and kenaf, are natural fibers with high specific stiffness and strength that have gained increasing attention in recent years. Bast fibers are advantageous in terms of their biodegradability and abundance in nature, making them promising candidates for automotive industry, structural composites, pulping and textile applications etc. There is a strong desire from industry for a high yielding natural cellulose fiber alternative to cotton due to the high volume of irrigation water, intensive use of pesticides, high cost and climatic conditions required to grow cotton. Before converting bast fibers into value-added products, degumming is a necessary step to separate cellulose and non-cellulose parts. Due to environmental consideration, degumming methods are developing to biodegradable green processes with high degumming efficiency. All works discussed in this review aim at revealing degumming methods for bast fibers and the potential for the design of eco-efficient processes. Objective appraisals toward the methods are discussed here, opening straight-forward access to the new chemicals and materials in the degumming industry.

麻、麻、亚麻、洋麻等韧皮纤维是一种具有较高比刚度和强度的天然纤维，近年来受到越来越多的关注。韧皮纤维在其生物降解性和自然界丰富性方面具有优势，使其成为汽车工业、结构复合材料、制浆和纺织应用等的有希望的候选者。大量灌溉水、大量使用杀虫剂、种植棉花所需的高成本和气候条件。在将韧皮纤维转化为增值产品之前，脱胶是分离纤维素和非纤维素部分的必要步骤。出于环保考虑，脱胶方法正在向可生物降解、脱胶效率高的绿色工艺发展。本综述中讨论的所有工作旨在揭示韧皮纤维的脱胶方法以及设计生态高效工艺的潜力。此处讨论了对这些方法的客观评估，为脱胶行业中的新化学品和材料开辟了直接途径。
