摘　　要：有色废旧纺织品的回收利用都需要对其进行剥色处理,剥色技术是影响其有效利用的关键,去除织物上的染料,避免因染料的存在而影响纺织品后续的处理。废旧纺织品的种类繁多,不同的纺织品所用纤维也不同,故剥色方法也不相同,单一织物的剥色相对较容易,混纺织物的剥色比较困难。对现有的剥色方法进行简单的阐述,发现采用氧化法和还原法为主的化学剥色方法会产生大量废水;采用物理剥色方法可以实现部分剥色剂等的回收利用,但其剥色效率低;生物、臭氧、光催化剥色方法不仅可以实现较高的剥色效率,而且剥色过程比较绿色环保,符合当下绿色环保的发展理念。The recycling of colored waste textiles needs to be stripped,and the color stripping technology is the key to its effective utilization,removing the dyes on the fabrics,so as to avoid the existence of dyes af⁃fecting the subsequent processing of the textiles.There are many kinds of waste textiles,and different tex⁃tiles use different fibers,so the color stripping methods are also different.It is relatively easy to strip a sin⁃gle fabric,and it is more difficult to strip a blended fabric.The existing color stripping methods are briefly described,it is found that the chemical color stripping method mainly using oxidation method and reduction method will produce a large amount of waste water;using physical color stripping method can realize the re⁃cycling of part of the color stripping agent,but its color stripping efficiency is low;biological methods,ozone,light catalytic color stripping method can not only achieve higher color stripping efficiency,but also the color stripping process is greener and environmentally friendly,which is in line with the current develop⁃ment concept of green environmental protection.
