Problems solved by technology

It should be noted that for polyester fabrics with poor hygroscopicity and low moisture regain (polyester fiber), one padding to absorb dyes cannot satisfy the full absorption, penetration and diffusion of disperse dyes in tight or heavy fabrics. Therefore, the above invention patent The application is not suitable for the continuous production and processing of thick and dark polyester fabrics

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...

[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...

Abstract

The invention discloses a pad dyeing method for polyester fabrics of thick and dark colors. Disperse dye 10 ~ 40g / L, penetrating agent JFC? 2g / L, dispersant MF? 2g / L, 3% sodium alginate slurry 25 ~ 40g / L, put it into the padding tank, add water to the total amount of the padding solution, immerse the polyester fabric in the padding solution in the padding tank, and dip the polyester fabric once into the padding solution- Pre-baking 90℃×1~1.5min-color fixing 175~205℃×1.5min-natural cooling out of oven-secondary padding raw dye solution-pre-baking 90℃×1~1.5min-color fixing 175~205℃× 1.5min-water washing-reduction cleaning, water washing, drying. The amount of dye used in the present invention is small, the rate of padding is low, and dyes are absorbed by pad dyeing in batches. The penetration and dyeing depth of polyester fabrics are better than those of traditional techniques, and the washing process before reduction cleaning reduces the washing burden of reduction cleaning. , the fabric has high color fixation rate, high dye utilization rate, brighter color, good color fastness, less dye wastewater, and is more environmentally friendly.

Description

technical field [0001] The invention relates to a method for dyeing polyester fabrics, in particular to a pad dyeing method for polyester fabrics with thick and dark colors. Background technique [0002] The traditional continuous dyeing methods of polyester fabrics include hot-melt pad dyeing process and high-temperature steam dyeing method, which have high production efficiency and short time for hot-melt continuous pad dyeing. and reduction cleaning to complete the dyeing process, the color fixing temperature is 185°C-220°C, and the time is 3.5-4min; the high-temperature steam dyeing method is to place the fabric in a high-temperature steamer at 180°C-190°C, and steam the fabric by adding steam Color fixation, time 7-10min. In actual production, the above-mentioned one-time dyeing process is usually used, but when processing dark-colored products of heavy polyester fabrics, it is often increased by increasing the amount of disperse dyes, or adding accelerators such as a ...
