Embodiment 1
[0035] This embodiment provides a yarn dyeing and finishing process for 3D fly-woven shoe uppers, the process steps are as follows:
[0036] (1) Degreasing process: put the yarn in the dyeing vat, add water and 0.1g / L of 713 multi-functional additive in turn, the bath ratio is 1:3, heat up to 50°C and keep it warm for 30 minutes to degrease the yarn oil, then drain, and get the deoiled yarn after draining;
[0037] (2) Dyeing process: high temperature and high pressure dyeing with disperse dyes is used for dyeing. The specific method includes adding water to the dyeing vat in sequence, SF series disperse dyes 0.7g / L, RY-216 series chelating dispersants 2g / L, anti-reducing agent A -2R 1g / L, PEL high-temperature leveling agent 2g / L, mix to form a dye liquor, then add glacial acetic acid with a concentration of 98% to adjust the pH of the dye liquor to 5.5, and dip the degreased yarn in the dyeing vat. In the dyeing solution, the bath ratio is 1:3, heat up to 130°C, keep warm fo...
Embodiment 2
[0042] This embodiment provides a yarn dyeing and finishing process for 3D fly-woven shoe uppers, the process steps are as follows:
[0043] (1) Degreasing process: put the yarn in the dyeing vat, add water and 0.5g / L of 713 multifunctional additive in sequence, and the bath ratio is 1:4, heat it up to 70°C and keep it warm for 20 minutes to degrease the yarn oil, then drain, and get the deoiled yarn after draining;
[0044] (2) Dyeing process: high temperature and high pressure dyeing with disperse dyes is used for dyeing. The specific method includes adding water to the dyeing vat in sequence, H-WF series disperse dyes 0.4g / L, Longsheng series disperse dyes 0.4g / L, RY-216 series Chelating dispersant 1.5g / L, anti-reducing agent A-2R 2g / L, PEL high-temperature leveling agent 0.1g / L, mix to form a dye liquor, then add glacial acetic acid with a concentration of 98% to adjust the pH value of the dye liquor to 4 , the bath ratio is 1:4, then dip the degreased yarn into the dye s...
Embodiment 3
[0049] This embodiment provides a yarn dyeing and finishing process for 3D fly-woven shoe uppers, the process steps are as follows:
[0050] (1) Degreasing process: put the yarn in the dyeing vat, add water and 0.3g / L of 713 multifunctional additive in sequence, and the bath ratio is 1:4, heat it up to 70°C and keep it warm for 20 minutes to degrease the yarn oil, then drain, and get the deoiled yarn after draining;
[0051] (2) Dyeing process: Dyeing is carried out by high-temperature and high-pressure dyeing with disperse dyes. The specific method includes adding water to the dyeing vat in sequence, DyStar series disperse dyes 0.5g / L, RY-216 series chelating dispersants 2g / L, anti-reduction Agent A-2R 0.5g / L, PEL high-temperature leveling agent 1.5g / L, mixed to form a dye liquor, then add glacial acetic acid with a concentration of 98% to adjust the pH value of the dye liquor to 5.5, and its bath ratio is 1:4, then Soak the degreased yarn in the dye liquor in the dye vat, r...
