Problems solved by technology

[0002] The traditional two-bath dyeing process is generally: after dyeing polyester, reduction cleaning, and then dyeing cotton, this process takes a long time, consumes a lot of energy, and has a lot of waste water. At the same time, it does not conform to the current national policy direction and development direction. Meet the needs of energy saving, emission reduction, environmental friendliness, green low carbon and sustainable development

Embodiment Construction

[0020] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the examples, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0021] A. Pre-dyeing treatment:

[0022] A1. At a temperature of 40-50°C, add surfactants and scouring agents to the dye bath solution in sequence at a bath ratio of 2:3, and treat the fabric for 2-5 minutes.

[0023] A2. Adjust the pH of the dye bath to 9-10 with an alkaline agent, add an oxidizing agent, raise the temperature of the dye bath to 55-65°C, and treat the fabric for 4-11 minutes.

[0024] A3. Continue to raise the temperature of the dye bath to 110-120°C, and treat the fabric for 20-25 minutes.

[0025] A4. At a temperature of 45-50°C, add an acid agent and an oxygen scavenger to the dye bath in sequence at a liquor ratio of 2:3, adjust the pH of the dye bath to neutral and adjust the oxygen content of th...

Abstract

The invention provides a dyeing process capable of increasing fixation rate of textiles. The dyeing process includes A, pre-dyeing treatment, B, dyeing treatment and C, post-dyeing treatment. The dyeing process has the advantages that the one-bath dyeing method integrates a cotton dyeing process with a terylene dyeing process; according to the one-bath two-step method, cotton is dyed at a low temperature, and terylene is dyed at a high temperature, so that feasibility of the one-bath dyeing method is improved, technological steps are simplified greatly, consumption of energy such as water andsteam is reduced, technological consumed time is shortened, and energy conservation, emission reduction and production efficiency improvement are realized; proper components and ratios of dyestuff andaids are selected according to the one-bath dyeing method, optimal technological steps and parameters (time and temperature) are combined, and accordingly, the dyeing effect of fabrics is improved greatly; polyester-cotton fabrics dyed and finished by the one-bath dyeing method have high color fastness to washing, insolation, friction, water and perspiration; dyeing uniformity is achieved, and dyeing defects are avoided.

Description

technical field [0001] The invention relates to the technical field of textile dyeing technology, in particular to a dyeing technology for improving the color fixation rate of textiles. Background technique [0002] The traditional two-bath dyeing process is generally: after dyeing polyester, reduction cleaning, and then cotton dyeing process, this process takes a long time, consumes a lot of energy, and has a lot of waste water. At the same time, it does not conform to the current policy direction and development direction of the country. It has the needs of energy saving, emission reduction, environmental friendliness, green low carbon and sustainable development. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a dyeing process that improves the color fixation rate of textiles. The one-bath dyeing method integrates the cotton dyeing process and the dyeing and was...
