Problems solved by technology

[0002] At present, the dyeing process in the wool spinning industry is cumbersome and the production cost is relatively high, especially for high-count blended knitting yarns, which are difficult to twist and dye
In order to ensure good dyeing fastness, reactive dyes for wool are generally selected for dyeing, but the dyeing property of this dye is poor, and the pass rate of one dyeing machine is only 80%. It is obviously not possible to produce with such a pass rate

Embodiment Construction

[0012] The technical solutions of the present invention will be further described below in conjunction with the embodiments.

[0013] 1. Traditional dyeing process: Take blended 72S / 2 as an example.

[0014] 1. The process flow is as follows:

[0015] (6) At room temperature 20°C, add penetrating agent, acetic acid, Albergo B (leveling agent) and dye (washed with 80°C water), and thread for 60 minutes.

[0016] (7) Turn on the steam to raise the temperature, and raise the temperature to 50° C. at a rate of 1° C. every 3 minutes, and keep warm.

[0017] (8) Add dispersants and cationic dyes, and thread for 30 minutes.

[0018] (9) Raise the temperature to 100° C. at a rate of 1° C. per minute, and keep warm.

[0019] (10) Fix the color for 60 minutes, cool down, and go out.

[0020] In this dyeing process, the dyeing time is 390 minutes, and the fixation time is 60 minutes, totaling 450 minutes. 80% qualified rate of one-time dyeing machine.

[0021] 2. Defects of traditi...

Abstract

The present invention provides a novel dyeing process for blended knitting yarns, which adopts a novel assistant PS liquid; leaves out formic acid, acetic acid, anhydrous sodium sulphate, a leveling agent, ammonium sulfate, an osmotic agent and a dispersant; simplifies production process; and stabilizes dyeing process. The novel dyeing process has the advantages that only the novel assistant agent PS liquid is used when dyeing by using a wool reactive weak acid dye and a cationic dye; dyeing defects in the process of high count yarn hank dyeing is not easy to generate, which improves the degree of dyeing and saves the dye; the stable dyeing-accelerating property can increase the improvement of color fastness; the dyeing time is shortened, which can save massive energy and increase labor productivity; a softening treatment for dyeing water is not necessary and tap water can be used for dyeing directly, and the water treatment cost is reduced because of no dyeing defects and seasonal aberration; and the assistant agent cost is reduced greatly.

Description

(1) Technical field [0001] The invention relates to a dyeing method in the printing and dyeing industry in the textile field, in particular to a new dyeing process of blended knitting yarn. (2) Background technology [0002] At present, the dyeing process in the wool spinning industry is cumbersome and the production cost is relatively high, especially for high-count blended knitting yarns, which are difficult to twist and dye. In order to ensure good dyeing fastness, reactive dyes are commonly used for dyeing wool, but the leveling property of this dye is poor, and the pass rate of one dyeing machine is only 80%. It is obviously impossible to produce with such a pass rate. (3) Contents of the invention [0003] Based on the above purpose, the present invention provides a fully automatic and high-precision color matching method. [0004] The technical scheme of the present invention is achieved in this way. [0005] The new dyeing process of blended knitting yarn of the ...
