Problems solved by technology

This method has the following disadvantages: 1. Due to multiple drainage and water addition, multiple cylinders of water are required to process one cylinder of cloth, and the water consumption and sewage discharge are high
2. The cloth is rope-like in the dyeing machine, which is difficult to clean completely and the cleaning effect is poor
3. There is no special washing machine, which occupies the dyeing machine, resulting in low utilization efficiency of dyeing machine equipment
[0004] However, this kind of continuous open-width washing machine, because it is connected in series, the length of the entire washing line is relatively large, and the requirements for installation space in the workshop are relatively high, and the operation of the fabric between adjacent units needs to be exposed outside the washing unit , first, it will cause the steam to be released in the washing unit, and the heat loss will be large; second, the temperature of the fabric will change too much, which will affect the quality of the fabric; third, there is still room for reduction of water consumption

Embodiment 1

[0023] This embodiment provides an energy-saving and emission-reducing dyeing post-processing process for nylon fabrics, and the dyeing post-processing process is performed in a closed three-dimensional combined washing machine. The closed three-dimensional combined washing machine used in this embodiment includes a washing machine 100, a cloth feed frame disposed on the input side of the washing machine 100, and a cloth discharge frame set at the output side of the washing machine 100. The fabric is sent into the washing machine 100 in the manner of a fabric outlet, and the washed fabric is sent out of the washing machine 100 in an open-width manner through the cloth discharge frame.

[0024] The washing machine 100 is separated by two layered partitions arranged at upper and lower intervals to form an upper layer 101 , a middle layer 102 and a lower layer 103 arranged in three layers. The soap washing unit 10 and the primary water washing unit 20 close to the cloth-out rack,...

Embodiment 2

[0040] This embodiment provides an energy-saving and emission-reducing dyeing post-treatment process for nylon fabrics. The dyeing post-treatment process is carried out in a closed three-dimensional combined washing machine, and the structure of the combined washing machine is the same as that described in the above-mentioned embodiment 1. Specifically include the following steps:

[0041] S1. Soaping treatment: The nylon fabric enters the soaping unit 10 in an open width. The soaping unit 10 is filled with the soaping liquid after the chemical material is added. The spray mechanism 60 sprays the surface of the fabric, and the spray pressure is 0.8MPa;

[0042] S2. One-time washing treatment: the nylon fabric after soaping treatment enters the first washing unit 20 in an open width, the liquid temperature in the first washing unit 20 is normal temperature, and the rotation speed is 45 m / min. The surface is sprayed, and the spray pressure is 0.8MPa;

[0043] S3, the first rol...

Embodiment 3

[0051] This embodiment provides an energy-saving and emission-reducing dyeing post-treatment process for nylon fabrics. The dyeing post-treatment process is carried out in a closed three-dimensional combined washing machine. The structure of the combined washing machine is based on the above-mentioned embodiment 1. A dirt filter device 80 is installed under each spray mechanism 60 in the inside, and each dirt filter device 80 includes a liquid collecting outer tank 81 which is immersed in and communicates with the treatment liquid in the corresponding unit through the filter assembly 84, and a liquid collecting outer tank 81 inside. The filter inner tank 82 and the roller 83 horizontally rotated on the guide plate 86 at the top of the liquid collecting tank 81, the input pipe of the spray mechanism 60 leads into the filter filter inner tank 82 and the filter filter inner tank The side wall of 82 is combined with a dirt filter assembly 85, the fabric is wound through the roller ...

Abstract

The invention relates to a dyeing post-treatment process for energy-saving and emission-reducing nylon fabrics. The nylon fabrics enter a closed three-dimensional combined washing machine in open width and are sequentially soaped in a soaping unit, washed once in a washing unit, and washed in a color-fixing unit. The color fixing treatment is carried out in the unit and the secondary water washing treatment is carried out in the secondary washing unit, and during the treatment process, the surface of the fabric is sprayed by the spraying mechanism, and the configured soaping liquid and Supplement the configured color-fixing liquid to the color-fixing unit, and while feeding new water to the secondary washing unit, discharge the treatment liquid in the soaping unit, and keep the secondary washing unit, primary washing unit and soaping unit respectively. The liquid flows and is in a dynamic equilibrium state, and the treatment liquid in the fixing unit determines the repeated use cycle according to the actual situation. The invention can improve the production efficiency of post-dyeing treatment, reduce water consumption and sewage, reduce energy consumption, and improve the utilization rate of the dyeing machine.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing post-treatment processes, in particular to an energy-saving and emission-reduction dyeing post-treatment process for nylon fabrics. Background technique [0002] The traditional overflow and air cylinder nylon elastic knitted fabric dyeing post-treatment process generally includes soaping, primary washing, color fixing and secondary washing, and the traditional post-processing is carried out on the dyeing machine. When the dyeing is completed, the dyeing machine needs to discharge the sewage and then add water to carry out post-treatment processes such as soaping, water washing, color fixing, cleaning, etc., and each process needs to discharge the sewage and add fresh water. This method has the following disadvantages: 1. Due to multiple drainage and addition of water, the treatment of one cylinder of cloth requires multiple cylinders of water, resulting in high water consumption and sewage ...
