Embodiment 1
[0022] please see image 3 , combined with image 3 The process shown in the process for dyeing wool fiber is made of 64S Huaji Aofu powder sold by Huaji Wool Products Co., Ltd. in Changzhou, Jiangsu Province, China. The quantity is 90KG, and the color is bright red. The container is the dyeing vat, for example, the wool fiber to be dyed is loaded into the wool barrel of the NC464B loose wool dyeing machine produced by Qianzhou Printing and Dyeing Equipment Co., Ltd., Wuxi City, Jiangsu Province, China, which is widely used in the industry. Put the wool to be dyed into the dye vat of the aforementioned dyeing machine, fill the vat with water at a bath ratio of 1:10, then start the circulation pump, add 1.5% leveling agent and 2% glacial acetic acid as auxiliary agents to the dye vat, and add The reactive dyes Venusel Scarlet BR1.8%, Venusel Red CQ3.4%, and Venusel Yellow CQ2.3% produced and sold by Korea Venusel Co., Ltd. will circulate for 20 minutes after adding, and then p...
