Washing-free shaping machine and dyeing and shaping process

Abstract

The invention discloses a washing-free shaping machine and a dyeing and shaping process. The washing-free shaping machine comprises a cloth feeding device, a dyeing tank, a padder, a water rolling device, a guide roller type hot air drying machine, a drying device of a drying room and a cloth discharging device, wherein the guide roller type hot air drying machine comprises an oven and upper and lower rows of guide rollers positioned in the oven, and a mesh belt conveying device is arranged in the drying device of the drying room. In the working process, fabrics sequentially pass through the cloth feeding device, the padder in the dyeing tank, the water rolling device, the guide roller type hot air drying machine, the mesh belt conveying device and the cloth discharging device in the drying device of the drying room. According to the invention, fabrics after dyeing is high in color fastness and low in surface floating color, and fabrics can be directly used without washing after dyeing, so that the beneficial effects of low energy consumption, low emission, short flow and high color fastness in the dyeing of the polyester fabrics is realized, and the dyed fabrics are bright and natural in color, good in dyeing effect, resistant to washing, not easy to discolor and lose color.

Description

technical field [0001] The invention relates to the field of fabric dyeing and setting, in particular to a washing-free setting machine and a dyeing and setting process. Background technique [0002] For a long time, dyeing technology has been completed under the joint action of dyes and various auxiliaries (such as dispersants, leveling agents, dyeing accelerators, etc.). These auxiliaries in the post-dyeing liquor have become the largest source of pollution in the dyeing industry. And the existing dyeing and setting process, such as the high-temperature and high-pressure dyeing method of disperse dyes and the hot-melt dyeing method that are often used in polyester fabric dyeing, in order to remove the floating color on the surface of the fabric and improve the color fastness of the dyed product, sufficient after-dyeing is required. Cleaning, the cleaning process greatly increases the water consumption, which is far more than that of dyeing water. At the same time, because...

Problems solved by technology

And the existing dyeing and setting process, such as the high-temperature and high-pressure dyeing method of disperse dyes and the hot-melt dyeing method that are often used in polyester fabric dyeing, in order to remove the floating color on the surface of the fabric and improve the color fastness of the dyed product, sufficient after-dyeing is required. Cleaning, the cleaning process greatly increases the water consumption, which is far more than that of dyeing water. At the same time, because a large amount of washing aids (such as detergents) are used in the cleaning process, the cleaning process produces a larger amount of emissions The high-chroma sewage that is difficult to treat increases the COD and BOD loads of the water body, and the drying treatment is required after washing and before the cloth is collected, which not only increases energy consumption, but also prolongs the production line, greatly increasing the complexity of dyeing and setting.
