Description
technical field [0001] The invention relates to a method for preparing wool, in particular to a method for preparing E-WOOL (easy to be healthy, easy to care for, and environmentally friendly) wool. Background technique [0002] Because there is a keratin layer (scale) structure on the surface of wool, it has disadvantages such as poor washing shrinkage performance, easy pilling, and poor hygroscopicity. In order to overcome these shortcomings, people have adopted the method of chemical treatment to process at present. However, the most popular anti-shrinkage processing method is to use salt (such as: liquid chlorine, hypochlorous acid, etc.), and salt is the cause of dioxins, which is harmful to the global environment and the health of workers in processing plants. harm. [0003] The international community's concern for the earth's environment is reflected in the rapid increase in the awareness of maintaining human health. In particular, the laws and regulations restrict...
