Embodiment 1

[0013] Embodiment 1: This embodiment is in figure 1 The overflow type ultra-low active bath ratio dyeing system shown in the device is completed, and its specific dyeing process includes the following steps:

[0014] (1) Pretreatment: immerse the knitted fabric in the dyeing vat 1 containing the pretreatment liquid determined as the lowest dyeing water level after measurement, and control and adjust the pretreatment at a temperature of 60-80°C for 20-30min; The material is all kinds of pure cotton knitted fabrics; the determination method of the minimum dyeing water level is: according to the capacity of the dyeing vat 1 in the dyeing system device, add the pretreatment liquid with the lowest running water level that can normally run, and then put it into the knitted fabric, and then When the knitted fabric is put in, the liquid in the dyeing vat 1 is gradually absorbed by the knitted fabric, and the dyeing system device will not be able to start. The auxiliary material cylin...

Embodiment 2-4

[0018] The dyeing process of the present embodiment 2-4 is basically the same as that of embodiment 1, and the reactive dye components and ratios used are different, specifically see the items listed in Table 1; the dyeing effect of each embodiment all reaches the requirements of the invention; its water saving rate reached more than 30%.

[0019] Table 1:

[0020]

Embodiment 5

[0022] In this embodiment, a dyeing vat 1 with a design capacity of 1500 kg and a low active-bath ratio overflow dyeing system device is selected. First, the dyeing active-bath ratio is determined to be 1:5-8, and then the actual water consumption of the dyeing vat 1 is measured, and Adjust the parameter values ​​of each water consumption as follows:

Abstract

The invention belongs to the technical field of textile processing and relates to a knitted fabric dyeing method with a low living bath ratio. The knitted fabric is stained by carrying out steps such as knitted fabric pretreatment, dyeing, knitted fabric after-treatment and finishing in a dyeing system device with a low living bath ratio; a regulation and control process of an ultralow pretreatment liquid water level and dye liquor water level is adopted to achieve energy-saving dyeing; the defects of large water consumption, large dye additive dosage, long dyeing duration and the like of the traditional knitted fabric overflow dyeing method are overcome, and the problems of high pollution and high energy consumption in knitted fabric dyeing are solved; the integral process is simple, the design principle is scientific, the application and operation are safe and reliable, the energy saving and emission reduction effects are good, and the dyeing is environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of textile processing, and relates to a new process for overflow dyeing of knitted fabrics with the lowest starting water level in an overflow dyeing system device, in particular to a method for dyeing knitted fabrics with a low active bath ratio. Background technique: [0002] At present, in the field of industrial production, the textile printing and dyeing industry is one of the industries with high energy consumption, high water consumption and high pollution. According to statistics, the coal consumption per 10,000 meters of cloth in my country is about 3 tons, and the power consumption is 450KW / The water consumption is 300-400 tons, the energy consumption is 3-5 times of the international advanced level, and the water consumption is 2-3 times. The water consumption of the printing and dyeing industry accounts for 80% of the water consumption of the entire textile industry, and the water pollution cause...
