Embodiment 1

[0043] The soaping agent selected for use in the soaping process is the XC-W soaping agent produced by BASF Company.

[0044] Wash with normal temperature water for 5 minutes in a water washing process.

[0045] After the water washing process is completed, drain the water for soaping. The soaping process is to prepare a 0.5g / L soaping solution, heat up to 70°C for 5 minutes, and then drain.

[0046] The second washing process uses normal temperature water for 5 minutes.

[0047] The oiling process is to prepare 0.5g / L oil agent first, wash at 35°C for 10 minutes, and drain.

Embodiment 2

[0049] The soaping agent selected for use in the soaping process is the XC-W soaping agent produced by BASF Company.

[0050] Wash with normal temperature water for 20 minutes in a washing process.

[0051] After the water washing process is completed, drain the water for soaping. The soaping process is to add normal temperature water and 3.0g / L of the above soaping agent, heat to 100°C, wash with water for 20 minutes, and then drain.

[0052] The second washing process uses normal temperature water for 20 minutes.

[0053] The oiling process is to prepare 3.0g / L oil agent first, wash at 45°C for 20 minutes, and drain.

Embodiment 3

[0055] The soaping agent selected in the soaping process is DL-EZC soaping agent.

[0056] Wash with normal temperature water for 12 minutes in a washing process.

[0057] After the first water washing process is completed, drain the water for soaping. The soaping process is to add normal temperature water and 1.8g / L of the above soaping agent, heat to 85°C, wash with water for 13 minutes, and then drain.

[0058] The second washing process uses normal temperature water for 15 minutes.

[0059]The oiling process is to prepare 1.5g / L oil agent first, wash at 38°C for 15 minutes, and drain.

Abstract

The invention discloses a reactive dyeing post-treatment method of viscose fibers without color fixing treatment, which can solve the technical problems of a plurality of washing times, large water consumption and high energy consumption in the reactive dyeing post-treatment of the viscose fibers, thereby achieving the purposes of saving energy, reducing consumption, improving efficiency and improving quality. The method changes the post-treatment procedures of the post-treatment dyeing into the procedures of water washing, soaping, water washing and oiling through the application of a complex soaping agent of XC-W in the reactive dyeing post-treatment of the viscose fibers, thereby leading the post-treatment to eliminate the color fixing treatment by using a color fixing agent, reducing the times of water washing, shortening the process time, effectively eliminating floating color on the surface of the dyed fibers, improving the color fastness to washing of dyed fabric, being conductive to unwinding of the reeled dyed fabric, reducing the burden on printing and dyeing wastewater treatment and being conductive to ecological environment protection.

Description

technical field [0001] The invention belongs to the technical field of fiber dyeing and finishing in the printing and dyeing industry. It is especially suitable for post-dyeing treatment of reactive dyes, and the invention specifically relates to a post-treatment method for reactive dyeing of viscose fibers without color fixing treatment. Background technique [0002] Viscose fiber is a cellulose fiber, usually dyed with reactive dyes. Dyeing with reactive dyes has the advantages of complete chromatogram and bright color, but reactive dyes are easy to hydrolyze, and there are dyes that are partially hydrolyzed and not combined with fibers on the dyed product. This part of the dye is easy to fall off during the washing process, affecting the color fastness and color. The vividness, especially the color fastness to washing. In order to improve the color fastness to washing of dyed goods, post-dyeing treatment must be carried out. [0003] The traditional post-treatment incl...
