Description

Technical Field

[0001] The invention relates to the technical field of cashmere dyeing, in particular to a cashmere deep black plant shellac dyeing device and process. Background Art

[0002] In nature, plants with pure melanin are very rare. Most of the existing plant dyeing methods are through the complexation of ferrous ions in green vitriol (ferrous sulfate compound) with tannic acid contained in some plants (terminal fruit, gallnut, pomegranate peel, yam, lotus seed shell, walnut peel, etc.) to form colorless ferrous tannate, which is oxidized by air to black tannic acid complex and deposited on the fiber to obtain black fabric. At present, foreign plant dyeing focuses on daily life use, mostly in the family unit, and has not yet formed a stable process. The more mature plant dyeing culture in China includes Hainan Li brocade and Liangshan Yi plant dyeing. Among them, Li brocade dyeing uses eight local plants, and the raw materials are mainly cotton thread. Liangshan Yi dyeing has direct dyeing method (similar to Li brocade), indigo dyeing method (alkaline reduction dyeing), mud dyeing method, etc., and the raw materials are mainly wool, linen, cotton, etc. The above-mentioned plant black dyeing process, under the premise of mordant dyeing, requires re-dyeing and over-dyeing to obtain a color close to black (the depth is shallow and the color is uneven), and the fastness is low. The process is complicated and difficult to industrialize.

[0003] Plant dyes are natural, green and sustainable dyes with less environmental impact and less carbon footprint than traditional chemical dyes. Therefore, studying plant dyes can promote sustainable development and reduce negative impacts on the environment. At the same time, plant dyeing also has cultural and historical value. The plant dyeing techniques of different regions and nationalities carry rich cultural heritage. Studying and protecting these techniques can not only promote the inheritance of cultural diversity, but also appreciate the role of dyeing technology progress in promoting the advancement of plant dyeing.
