Embodiment 1

[0041] 100Kg desized polyester woven fabric is put into intermittent high temperature and high pressure overflow dyeing machine, bath ratio is 1: 20, add 4Kg borax and 2Kg dye composition of the present invention respectively at 40 ℃, with per minute 1 Raise the temperature to 125°C at a heating rate of ~2°C, run for 45 minutes, drain the water, then wash with clean water at 40-50°C for 10 minutes, then wash with a weak acidic solution with a pH value of 4.5-6.5 for 10 minutes, take it out of the tank, and dry it.

Embodiment 2

[0043] 100Kg desized polyester woven fabric is put into intermittent high-temperature and high-pressure overflow dyeing machine, the bath ratio is 1: 20, and 10Kg borax and 2Kg dye composition of the present invention are added respectively at 40 ° C, at 1 per minute Raise the temperature to 135°C at a heating rate of ~2°C, run for 40 minutes, drain the water, then wash with clean water at 40-50°C for 10 minutes, then wash with a weak acidic solution with a pH value of 4.5-6.5 for 10 minutes, take it out of the tank, and dry it.

Embodiment 3

[0045] 100Kg polyester knitted fabric is put into intermittent high temperature and high pressure overflow dyeing machine, bath ratio is 1: 20, when 40 ℃, add 10Kg borax and 5Kg dyestuff composition of the present invention respectively, at the rate of 1~2 ℃ per minute Raise the heating rate to 135°C, run for 40 minutes, drain the water, then wash with 40-50°C water for 10 minutes, then wash with a weak acid solution with a pH value of 4.5-6.5 for 10 minutes, take it out of the tank, and dry it.

Abstract

The invention relates to a dye composition which is one or more than two mixtures selected from a structural general formula (I), a structural general formula (II) and a structural general formula (III), or is one or more than two mixtures selected from a structural general formula (IV) and a structural general formula (V), or is one or more than two mixtures selected from a structural general formula (VI), a structural general formula (VII), a structural general formula (VIII) and a structural general formula (IX). Taking borax as medium, the method for polyester fiber fabric alkalinity dye based on the dye composition can achieve acid dyeing effect, and the alkalinity dyeing effect is better than the acid dyeing effect. According to the method and the utilization of the dye composition, the requirement of short dyeing process is met, and the purpose of lowering the energy consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a dye composition and a method for alkaline dyeing of polyester fiber fabrics using the dye composition. Background technique [0002] Polyester fibers are dyed with disperse dyes, which were usually carried out in acidic medium. In order to achieve the requirements of energy saving, energy saving and emission reduction in polyester printing and dyeing, the dyeing medium of polyester fiber fabric must use alkaline medium, so as to realize the requirement of short dyeing process and achieve the purpose of reducing energy consumption. [0003] In order to achieve alkaline medium dyeing of polyester fiber, it is extremely important to select alkali-resistant disperse dyes. Due to the difference in structure, disperse dyes show different alkali resistance. Therefore, the selection of alkali-resistant disperse dyes is the basis for the current develo...
