Embodiment 1
[0025] The PLA filament fabric was treated with low-temperature plasma in a low-temperature plasma equipment. The treatment conditions were: power 60W, time 60S, and the treatment atmosphere was air. The treated PLA filament fabric was dyed with Dianix (Blue) XF. Dyeing conditions: dye 1% (o.w.f), diffusing agent NNO 1g / L, bath ratio 1:30, adjust the pH value to 4-5 with acetic acid, the dyeing process is as follows figure 1 Shown: press figure 1 After dyeing with the shown heating curve, washing with water, reducing washing, washing with water and drying.
[0026] The PLA filament fabric dyed in Example 1 and the PLA filament fabric treated by conventional dyeing process were tested for dye uptake and k / s value. The test results showed that the dye uptake of PLA filament fabric without plasma treatment was 46.7%, k / s value is 3.12, the dye uptake rate of PLA filament fabric treated by plasma is 58.9%, k / s is 4.23, dye uptake rate and k / s growth rate are 26.12% and 35.58%, respect...
Embodiment 2
[0028] The PLA filament fabric was treated with low-temperature plasma in a low-temperature plasma equipment. The treatment conditions were: power 100W, time 100S, and the treatment atmosphere was air. The treated PLA filament fabric was dyed with Dianix (Blue) XF. Dyeing conditions: dye 1% (o.w.f), diffusing agent NNO 1g / L, bath ratio 1:30, adjust the pH value to 4-5 with acetic acid, the dyeing process is as follows figure 2 Shown: press figure 2 After dyeing with the shown heating curve, washing with water, reducing washing, washing with water and drying.
[0029] The PLA filament fabric dyed in Example 2 and the PLA filament fabric treated by the conventional dyeing process were tested for dye uptake and k / s value. The test results showed that the dye uptake of PLA filament fabric treated by plasma 64.1%, k / s was 5.23, dye uptake rate and k / s growth rate were 37.26% and 67.63%, respectively.
Embodiment 3
[0031] Low-temperature plasma treatment was performed on the PLA filament fabric in a low-temperature plasma equipment. The treatment conditions were: power 100W, time 100S, and treatment atmosphere as air. The treated PLA filament fabric was immersed in 30% acrylic acid solution for 60 minutes. The PLA filament fabric was then dyed with Dianix (Blue) XF. Dyeing conditions: dye 1% (o.w.f), diffusing agent NNO 1g / L, bath ratio 1:30, adjust the pH value to 4-5 with acetic acid, the dyeing process is as follows image 3 Shown: press image 3 After dyeing with the shown heating curve, washing with water, reducing washing, washing with water and drying.
[0032] The PLA filament fabric dyed in Example 3 and the PLA filament fabric treated by conventional dyeing process were tested for dye uptake and k / s value. The test results showed that the dye uptake of PLA filament fabric treated by plasma was 72.1%, k / s was 6.32, dye uptake rate and k / s growth rate were 54.39% and 103.56%, respec...
