Embodiment 1
[0023] Embodiment 1: a kind of dyeing process of chiffon fabric, as figure 1 Shown, comprise the following steps, S1, configure dye liquor, dyestuff selects conjugated cationic dye for use, adds NaOH, water purifying agent and β-cyclodextrin, by weight, NaOH: dyestuff: water purifying agent is 20:1: 0.5, polyaluminum chloride is selected as the water purifying agent, the dosage of β-cyclodextrin in the dye solution is 2g / L, the dosage of dye is 1% (owf), and the liquor ratio is 1:20. Put the prepared dye solution into the dyeing solution Inside the machine, heat up to 40°C.
[0024] S2. Weigh the chiffon fabric, add the chiffon fabric to be dyed into the dye solution in the dyeing machine, raise the temperature to 60°C at 0.7°C / min, and keep warm at 60°C for 5 minutes.
[0025] S3, heating the dye solution in step S2 to 90°C at 0.7°C / min, adding nano-silver particles, and incubating at 90°C for 5 minutes, by weight, the ratio of nano-silver particles:dye is 0.4:1.
[0026] S...
Embodiment 2
[0032] Embodiment 2: A dyeing process for chiffon fabrics, the difference from Example 1 is that, S4, the dye solution in step S3 is heated up to 100°C at 0.8°C / min, and kept at 100°C for 10 minutes .
[0033] Color fastness test: Refer to GB / T3921-2008 to measure the color fastness to soaping of chiffon fabrics, refer to GB / T3920-2008 to measure the color fastness to rubbing of chiffon fabrics, and refer to GB / T5713-1997 to measure the color fastness to rubbing of chiffon fabrics The color fastness to water of the spun fabric, and the results obtained by the test are listed in Table 1.
[0034] Determination of dye uptake rate: test the absorbance of the dye mother liquor and dyeing residue with a spectrophotometer, and calculate the dye uptake rate with the following formula: E=(1-mA1 / nA2)×100%. E is the dye uptake rate, A1 is the absorbance of the dye solution; A2 is the absorbance of the dye residue, m is the dilution multiple of the dye solution; n is the dilution multip...
Embodiment 3
[0035] Embodiment 3: A dyeing process for chiffon fabrics. The difference from Embodiment 2 is that, in S3, the dye solution in step S2 is heated to 90° C. at 0.7° C. / min, and kept at 90° C. for 5 minutes.
[0036] Color fastness test: Refer to GB / T3921-2008 to measure the color fastness to soaping of chiffon fabrics, refer to GB / T3920-2008 to measure the color fastness to rubbing of chiffon fabrics, and refer to GB / T5713-1997 to measure the color fastness to rubbing of chiffon fabrics The color fastness to water of the spun fabric, and the results obtained by the test are listed in Table 1.
[0037] Determination of dye uptake rate: test the absorbance of the dye mother liquor and dyeing residue with a spectrophotometer, and calculate the dye uptake rate with the following formula: E=(1-mA1 / nA2)×100%. E is the dye uptake rate, A1 is the absorbance of the dye solution; A2 is the absorbance of the dye residue, m is the dilution multiple of the dye solution; n is the dilution mu...
