Abstract

The invention discloses a bamboo fiber dyeing technology, which comprises the following flows: pretreatment, dyeing, hot water washing, cold water washing, soaping and water washing. The capillary effect of the bamboo fiber can be improved through the pretreatment, the oil removal is prepared for dyeing, the dyeing problem due to manual operation can be effectively avoided by linear addition of anhydrous sodium sulfate and sodium carbonate, the operation is simple, and the dyeing is convenient.

Description

[0001] technical field [0002] The invention belongs to a dyeing process, in particular to a bamboo fiber dyeing process. [0003] Background technique [0004] Bamboo fiber is man-made cellulose fiber, which can be dyed with reactive dyes, vat dyes, direct dyes, etc. Reactive dyes are widely trusted and used by people because of their unique bright and eye-catching color, environmental protection, excellent fastness, and simple dyeing process. However, bamboo fiber dyeing has problems such as uneven coloring, color spots, white spots, impermeable dyeing and poor dark color enhancement. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects existing in the prior art, the object of the present invention is to provide a bamboo fiber dyeing process with simple operation and uniform coloring. [0007] Bamboo fiber dyeing technique provided by the invention, technological process is as follows: [0008] (a) Pretreatment: put bamboo fi...
