Embodiment 1

[0053] The same bath dyeing method of acrylic fiber and viscose (cotton) fiber, comprises the following steps,

[0054] (1) Before dyeing in the same bath:

[0055] Acrylic and viscose (cotton) fiber blended yarns are woven into knitted fabrics in a weight ratio of 1:1; marked as A50 / R(C)50.

[0056] (2) Dyeing in the same bath:

[0057]Put the knitted fabric mentioned in step (1) into the overflow dyeing machine, add water, then sequentially add chelating agent 8108 and pH regulator AC-608, then heat up to 30°C, add cationic dye after 10 minutes of operation, and add after 20 minutes of operation For reactive dyes, after running for 20 minutes, add sodium sulfate. After running for 20 minutes, heat up to 95°C at a rate of 1.5°C / min. After running for 50 minutes, enter the exchanger to cool down. After cooling down to 40°C, drain the water, and add heat at 50°C. Wash with water for 20 minutes to obtain knitted fabric after dyeing;

Abstract

The invention discloses an acrylic fiber and viscose (cotton) fiber apposition dyeing method relating to the technical field of blended yarn weaved fabric dyeing. The method comprises the following steps: (1) performing apposition dyeing pretreatment; (2) performing apposition dyeing; and (3) performing apposition dyeing post-treatment. The method has the advantages of simple production process, stable process control and energy conservation, and the related problems in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of blended fabric dyeing, in particular to a method for dyeing acrylic and viscose (cotton) fibers in the same bath. Background technique [0002] Traditional acrylic viscose (acrylic cotton) products are produced in two baths and two steps. During production, acrylic fiber is dyed first and then viscose (cotton) fiber or viscose (cotton) fiber is dyed first and then acrylic fiber is dyed. This two-bath two-step dyeing process has the following problems: [0003] One is that the dyeing process in two baths and two steps takes a long time, has the disadvantage of a long production cycle, and also wastes energy, which seriously restricts the improvement of production efficiency, so it needs to be improved. [0004] The second is that the two-bath two-step dyeing process is complicated, which brings a lot of troubles to technical workers, affects the stable control of the production process, leads to unstable ...
