Examples
Embodiment 1
[0031] AF-R orange (azo type)
[0032] Test cloth: polyester T100D / 144F semi-dull
[0033] Disperse dye: AF-R orange Liquor ratio: 1:20
[0034] Test equipment: Rapid ECO-24
[0035] Test process: high temperature, high pressure and less water dyeing process:
[0036] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry
[0037] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is ten times.
[0038] The relevant performance test results are shown in Table 1.
Embodiment 2
[0046] FB red (anthraquinone type)
[0047] Test cloth: polyester T100D / 144F semi-dull
[0048] Disperse dye: FB red bath ratio: 1:50
[0049] Test equipment: Rapid ECO-24
[0050] Test process: less water dyeing process:
[0051] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry
[0052] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is ten times.
[0053] The relevant performance test results are shown in Table 2.
Embodiment 3
[0062] color matching navy blue
[0063] Test cloth: polyester T100D / 144F semi-dull
[0064] dye:
[0065] C-BN Black 0.6%
[0066] S-5BL Ruby 0.2%
[0067] ES-BR Deep Blue 1.2%
[0068] Bath ratio 1:20
[0069] Test equipment: Rapid ECO-24
[0070] Test process: less water dyeing process:
[0071] Weighing (disperse dye 2% owf, high temperature leveling agent SY-WS 1% owf) → chemical material → dyeing (pH value 5, heat up to 130°C at 1.8°C / min and keep it for 40min, then cool down to 80°C) → Add reduction cleaning agent (3% owf) → reduction cleaning (pH value 5, heat up to 90°C at 1.8°C / min and keep it warm for 25min, then cool down to 80°C) → iron dry
[0072] In the water-less dyeing process, the residual liquid after reduction and cleaning is recycled again and used as water for the next dyeing, and the cycle is eight times.
[0073] The relevant performance test results are shown in Table 3.
