Embodiment 1
[0026] Embodiment 1 Dyeing of polyester decorative tape
[0027] Prepare the padding solution, weigh 10g / L of low-temperature dye disperse red, 2g / L of dispersant MF, 2g / L of penetrating agent JFC and 25g / L of 3% sodium alginate, put them into the padding tank, add water to the total amount of the padding solution , Stir evenly, immerse the polyester decorative tape into the dye solution in the rolling tank → pass through the rolling press → immerse in the dye solution → rolling (the rolling rate is 60%). Put the padding polyester decorative tape into the oven for pre-baking (90°C, 1min), enter the oven to fix the color (175°C, 1.5min), and leave the oven to cool; put the once-dyed polyester decorative tape into the padding groove again Dye liquor, pre-baking (90°C, 1min), baking and fixing reaction (175°C, 1.5min), out of the oven;
[0028] Wash the secondary dyed polyester decorative tape with water, reduce cleaning (sulfate 3g / L, caustic soda 3g / L, 80℃×3min), wash with wat...
Embodiment 2
[0030] Embodiment 2 polyester fabric dyeing
[0031] Prepare the padding solution, weigh 15g / L of low-temperature dye disperse yellow, 2g / L of dispersant MF, 2g / L of penetrating agent JFC and 30g / L of 3% sodium alginate, put them into the padding tank, add water to the total amount of the padding solution , Stir evenly, immerse the polyester fabric in the dye solution in the rolling tank → pass through the rolling press → immerse in the dye solution → rolling (the rolling rate is 45%). Put the padded polyester fabric into the oven for pre-drying (90°C, 1.5min), enter the oven to fix the color (180°C, 1.5min), and leave the oven to cool; put the polyester fabric once dyed into the padding tank again for padding and original dyeing Liquid, pre-baking (90°C, 1.5min), baking and fixing reaction (180°C, 1.5min), out of the oven;
[0032] Wash the secondary dyed polyester fabric with water, reduce cleaning (3g / L sodium hydrosulfite, 3g / L caustic soda, 80℃×3min), wash with water, an...
Embodiment 3
[0034] Example 3 Polyester binding tape dyeing
[0035] Prepare padding solution, weigh 15g / L of medium-temperature disperse blue dye, 2g / L of dispersant MF, 2g / L of penetrating agent JFC and 35g / L of 3% sodium alginate, put them into the padding tank, add water to the total amount of padding solution , Stir evenly, immerse the polyester strap into the dye solution in the rolling tank → pass through the rolling press → immerse in the dye solution → rolling (the rolling rate is 45%). Put the padding polyester strap into the oven for pre-baking (90°C, 1.5min), enter the oven for color fixation (190°C, 1.5min), and leave the oven to cool; put the dyed polyester strap into the padding tank again for padding The original dye solution, pre-baking (90°C, 1.5min), baking and fixing reaction (190°C, 1.5min), out of the oven;
[0036] Wash the secondary dyed polyester strapping with water, reduce cleaning (3g / L sodium hydrosulfite, 3g / L caustic soda, 80℃×3min), wash with water, and dry...
