Embodiment Construction
[0028] like figure 2 As shown, a polyester fabric scouring, bleaching and dyeing process includes the following steps:
[0029] 1) Add auxiliaries, add alkaline leveling agent, dispersant, scouring agent, degreasing agent, and dyeing accelerator to the bath after entering the cloth at room temperature;
[0030] 2) Add disperse dye, add auxiliary agent and add disperse dye after running for 5-15 minutes;
[0031] 3) Warm up and add lye, add disperse dye and gradually heat up, add lye when the temperature reaches 70 °C, if the cloth has mildew spots, add H 2 O 2 ;
[0032] 4) warming up, gradually warming up to 130°C;
[0033] 5) Keep warm for 20-40 minutes at a temperature of 130 degrees;
[0034] 6) Cool down and wash with water.
[0035] Wherein, step 3) the heating rate from normal temperature to 70 ℃ is 3 ℃ / min, step 4) the heating rate from 70 ℃ to 90 ℃ is 2 ℃ / min, and the heating rate from 90 ℃ to 130 ℃ is 1.3 ℃ / min min.
[0036] The polyester fabric surface is a...

The invention discloses a scouring, bleaching and dyeing process for polyester fabric. The scouring, bleaching and dyeing process comprises the following steps: 1) addition of additives: an alkaline leveling agent, a dispersing agent, a scouring agent, an deoil agent and a dyeing accelerant are added to a bath solution after fabric feeding at the room temperature; 2) addition of a disperse dye: operation is performed for 5-15 min after addition of the additives, and then the disperse dye is added; 3) heating and addition of alkaline liquor: heating is performed gradually after the disperse dye is added, the alkaline liquor is added when the temperature reaches 70 DEG C, and H2O2 is required to be added if the fabric has mildew stains; 4) temperature increasing: the temperature is increased gradually to 130 DEG C; 5) temperature keeping: the temperature is kept at 130 DEG C for 20-40 min; 6) temperature reduction and washing. According to consideration of energy saving, emission reduction, improvement of product quality and increase of production efficiency, the polyester home fabric is dyed with a disperse dye alkaline bath, the process procedure can be shortened, energy saving and emission reduction can be realized, further, problems caused by spinning oil, a sizing agent and oligomers can be solved, and the product quality can be improved.
Description
technical field [0001] The invention relates to a textile printing and dyeing technology, in particular to a dyeing process for polyester home textile fabrics. Background technique [0002] With the popularization of high-speed yarn technology, in the production process of polyester spinning, chemical fiber factories must use high-speed spinning oil to oil the tow in order to increase production capacity and ensure quality, so as to increase the smoothness during spinning, and Reduce the friction between the tow and the silk path in the production process; ② increase the bundle; ③ enhance the antistatic property and other important functions, but the spinning oil must be removed by alkali and surfactant during the printing and dyeing of polyester fabrics. . In addition, polyester fabric products are often subjected to appropriate alkali reduction pretreatment due to style requirements. In order to meet the subsequent acid conditions for staining, such as figure 1 As shown...
