Embodiment 1

[0017] The pretreatment dyeing one-bath one-step process is as shown in accompanying drawing 1, selects pure polyester knitted fabric, and the weight is 250KG. In the high temperature and high pressure overflow dyeing machine, put dyeing water, put the polyester fabric into the dyeing machine for circulation, add 7.50KG soda ash and 7.50KG scouring agent HE0815, add 0.600KG disperse dye shown in formula (1), the total liquid volume For 2500 liters, the pH value is 10.8.

[0018]

[0019] Heat up to 80°C at a heating rate of 2°C / min, then heat up to 130°C at a heating rate of 1°C / min, and keep warm for 45 minutes. Cool down to 80°C to discharge the residual liquid, wash in hot water at 80°C for 10 minutes, and finally wash in cold water at room temperature for 6 minutes, and dry the cloth to obtain a bright yellow fabric. The fabric surface is clean, the color is uniform, and the handle is smooth and soft. Fastness test results are shown in Table (1):

Abstract

The invention discloses a polyester fiber fabric coloring method and the fabric adopting the method and manufactured by using the method. The method is a method which combines pretreatment and coloring to carry out one bath one step coloring. The dosage of alkali is 0.3 to 30g / l, and the bath ratio is 1:3 to 1:40 under the strong alkalinity condition that the pH of a dye bath is equal to or more than 10.6 and is equal to or less than 14. An alkali resistance dispersing dye is used for carrying out the one bath one step coloring on the polyester fiber and a fabric thereof under the condition of having a pretreatment addition agent or having no pretreatment addition agent. The invention carries out the one bath one step coloring under the strong alkalinity condition. The alkalinity condition can effectively remove the slurry and oil agent on a polyester fabric, overcome the defects of generating a plurality of dye defects caused by the precipitation of other decomposing products such aspolyester oligomer in an acid bath and simultaneously bring the effect of neat fabric surface and good fabric style which can meet the requirement of fastness that usually needs no reduction and cleaning. The amount reducing effect of the alkali can also lead the fabric to be smooth and the hand feeling to be better. The method simplifies the coloring technique, reduces the waste water of pretreatment, saves energy, reduces the manufacture cost and improves the labor production efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to an environment-friendly, energy-saving and consumption-reducing dyeing method suitable for polyester fiber fabrics and its application. Background technique [0002] In the past ten years, the problems of energy shortage and environmental pollution have become increasingly prominent. At the same time, the competition in the international textile market has become more intense, requiring high processing efficiency and low processing costs. This has further promoted the research and development of the one-bath one-step process for pre-treatment dyeing in various countries around the world. , and there is a certain expansion in the fabrics used, dyes, processes and even auxiliaries, which fully demonstrates that pretreatment and dyeing one-bath one-step method are one of the development trends of modern fabric dyeing and finishing. [0003] For a long time, polyest...
