Abstract

The invention discloses a continuous polyester fabric padding and dyeing method free of a boiling and washing process. The method includes steps: step one, proportionally and uniformly mixing dispersedyes, water-absorbent resin, a polyester repair agent, an anionic surfactant, a color fixing agent and a moisture absorbent in softened water to obtain dyeing working solution; step two, subjecting polyester fiber fabrics to padding in the dyeing working solution prepared in the step 1; step three, after padding in the dyeing working solution, subjecting the polyester fiber fabrics to drying, baking and cropping at 140-220 DEG C to complete continuous dyeing of the polyester fiber fabrics. Technical process shortening and remarkable production efficiency improvement are realized, energy saving, consumption reduction, environmental friendliness and freeness of dyeing sewage discharging are realized, production cost of dyeing and printing enterprises is reduced while economic benefits are increased, and discharging of dyeing sewage is avoided.

Description

technical field [0001] The invention relates to a polyester fabric dyeing method, in particular to a polyester fabric continuous pad dyeing method and the polyester fabric prepared by the method. Background technique [0002] my country is a big country in the production and consumption of textiles, and polyester fiber is used in the largest amount in textiles, accounting for more than 60% of all fibers. And numerous polyester fiber textiles mainly adopt the high temperature and high pressure overflow dyeing method. The high-temperature and high-pressure dyeing method is carried out in a humid state with high temperature and pressure. It must be pressurized below 2atm (2.02×105Pa), and the temperature of the dyeing bath can be increased to 120-130°C. Due to the increase in temperature, the chain segments of fiber molecules move violently. The more and larger the instantaneous pores are, the faster the diffusion of dye molecules is at this time, which increases the diffusion...
