Step 2, ACID DYES dyeing wool; Clear water is refilled in dye vat, add ACID DYES, glauber salt, levelling agent, acid for adjusting pH value is stabilized in 4.5 ~ 5, with the ramp to 70 DEG C of 1 ~ 1.5 DEG C/min, is incubated 10 minutes, 98 DEG C of insulations 45 minutes are warming up to again with 0.5 DEG C/min of heating rate, gradually after cooling, dye liquor of draining, dye vat injects 80 DEG C of hot water, add soaping agent to soap 5 minutes, draining;

Step 3, fixation; Dye vat is intake, and normal temperature adds glacial acetic acid 0.5g/L, and be warming up to 50 DEG C of insulations 15 minutes, draining, dye vat water filling adds color-fixing agent 1 ~ 5g/L, softener 1 ~ 3g/L, is warming up to 50 DEG C of insulations 30 minutes, draining.

In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:

Dyeing and finishing technology hinge structure of the present invention is little to Wool Fibre Damage, and simultaneously few to wool staining in disperse dyeing of polyester process, even dyeing, product quality is guaranteed.

Detailed description of the invention

Case study on implementation:

Yarn count is 40s/1, and yarn composition is 60% terylene/40% wool, and dye is dark, bath raio 1:10.

In pretreatment procedure (as shown in Figure 1), dye vat enters water, add refining agent 3g/L, kiering enzyme 2g/L, hydrogen peroxide (mass fraction is 30%) 15g/L, with the heating rate of 2 DEG C/min be warming up to 90 DEG C, insulation 45min carry out refining bleaching, the solution of then draining after processing, again in dye vat, water is injected, be warmed up to 60 DEG C of insulations to clean for 15 minutes, draining, water filling enters dye vat and is warming up to that 50 DEG C add deoxygenase 0.1g/L, neutralizing acid 0.5g/L is incubated 20 minutes and makes the pH value of solution control 6 ~ 7.5, the solution after process of then draining again.
