Description

Technical Field

[0001] The invention relates to the technical field of cloth dyeing, in particular to a plant dye overflow cylinder dyeing process. Background Art

[0002] Organic plant dyes refer to pigments extracted from flowers, grasses, trees, stems, leaves, fruits, seeds, barks, roots, etc. in nature. For example, the scraps and sawdust after the production of mahogany furniture are rich in a large number of polyphenol pigments, which are non-toxic, harmless, pollution-free and renewable. They are used for textile dyeing, which not only improves the added value, but also achieves ecological protection of the environment. Therefore, how to extract natural plant pigments and obtain organic plant dyes with zero emissions, zero pollution and good color fastness is a problem that needs to be solved at present.

[0003] The original meaning of textile is the general term for spinning and weaving. However, with the continuous development and improvement of the textile knowledge system and discipline system, it also includes non-woven fabric technology and modern three-dimensional weaving technology. The overflow cylinder belongs to textile equipment, but it still has the following disadvantages in actual use:

[0004] The existing overflow cylinder generally drives the cloth to rotate through a motor to carry out its dyeing treatment, but the cloth wound on the reel has different degrees of wetting inside and outside, which affects the dyeing operation of the cloth; the existing overflow cylinder used for printing and dyeing will carry a large amount of dye and water after the cloth is dyed. During the transmission process on the cloth discharge wheel, the dye and water on the cloth will splash or drip on the floor of the workshop. The floor of the workshop is easy to slip after water accumulation, and workers are easy to slip when walking in the workshop, which is inconvenient to clean. In addition, the cloth needs to be manually fixed at the beginning of the discharge, and the operation process is cumbersome, and there are certain safety hazards. Summary of the invention
