Problems solved by technology

In the actual production process, the variety is constantly changing, so the control of the pH value of the fabric is very unstable. At present, an automatic control acid addition facility has been developed, but the test probe needs to be cleaned and corrected according to the requirements, which is troublesome to operate.

Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a delivery system for adjusting the pH value of a printing and dyeing washing machine, including a liquid storage tank 1 and a washing machine 2, and the washing machine 2 includes five washing tanks 3;

[0033] The washing tank 3 is divided into a clear water area 301 and an adjustment area 302, the number of the clear water area 301 is 2, and the number of the adjustment area 302 is 3;

[0034] The liquid storage tank 1 is connected to the conditioning area 302 of the water washing tank 3 through a pipeline, and the pipeline includes a main pipeline 4 and a branch pipeline 5;

[0035] Valve B6, flowmeter A7 and valve A8 are arranged in sequence on the main pipeline 4 to control the total flow of liquid carbon dioxide entering the branch pipeline 5; After the carbon dioxide inside is treated, it can be opened to improve the controllability and accuracy of the flow of liquid carbon dioxide, and at the same time,...

Embodiment 2

[0042] Fabric surface: pure cotton thin fabric, fabric weave specification is C100×80 230×200 fabric, fabric weight 120g / m 2 ;Cloth color: emerald blue;

[0043] Cloth surface treatment process: After the above-mentioned cloth surface is singed, desized, bleached, mercerized, whitened and dyed, the pH value of the cloth surface is measured to be 8.3-8.6;

[0044] Conveyor system setup:

[0045] Such as figure 1 As shown, open valve B6, flow meter A7 and valve A8, control the delivery pressure to 0.2MPa, and open the flow meter B9 and valve C10 above the second branch pipeline 5 and the third branch pipeline 5 counted from the left in the adjustment area 302, and control The amount of liquid carbon dioxide that enters the second branch pipeline 5 and the third branch pipeline 5; after the liquid carbon dioxide enters the conditioning area 302 and counts the second washing tank and the third washing tank from the left, wait for 30 minutes, and the cloth begins to enter the condi...

Embodiment 3

[0052] Cloth surface: polyester cotton Thick fabric: T / C 20×16 100×56 fabric, weight 210g / m 2 ;Cloth color: rose red;

[0053] Cloth surface treatment process: After the above-mentioned cloth surface is singed, desized, bleached, mercerized and dyed, the pH value of the cloth surface is measured to be 8.3-8.6;

[0054] Conveyor system setup:

[0055] Such as figure 1 As shown, open valve B6, flowmeter A7 and valve A8, control the delivery pressure to 0.4MPa, and open the flowmeters above the first branch pipeline 5, the second branch pipeline 5 and the third branch pipeline 5 in the regulation area 302 from the left B9 and valve C10 control the amount of liquid carbon dioxide entering the first branch pipeline 5, the second branch pipeline 5 and the third branch pipeline 5; the liquid carbon dioxide enters the adjustment area 302 and counts the first washing tank, the second washing tank and the second washing tank from the left After the three washing tanks, wait for 30 mi...

Abstract

The invention provides a method for adjusting a pH value of a printing and dyeing washing machine and a conveying system used for the same. The method comprises the steps that after a cloth surface isinitially cleaned in a clean water area, the cloth surface is introduced into an adjustment area for continuous cleaning. Carbon dioxide gas is introduced into the adjustment area to adjust the pH value of a solution in washing tanks. After the cloth surface is cleaned in the adjustment area, the pH value is between 5.0 and 7.5. The conveying system comprises a liquid storage tank. A washing machine comprises n washing tanks. The washing tanks are divided into clear water areas and adjustment areas. The number of the clear water areas is a, and the number of adjustment areas is b, wherein a+b=n. The adjustment areas of the washing tanks are connected with the liquid storage tank by pipelines, and a flow meter A and a valve A are arranged in sequence on a connecting pipeline. Using the method to adjust the pH value of the cloth surface, the pH range of the cloth surface is maintained between 5.0 and 7.5, and the pH value is stable. The conveying system is used to transport carbon dioxide, and has the advantages of high utilization rate of carbon dioxide and stable pH change of the cloth surface.

Description

technical field [0001] The invention relates to the technical field of pH adjustment of printing and dyeing cloth, in particular to a method for adjusting the pH value of a printing and dyeing washing machine and a conveying system used in the method. Background technique [0002] The textile industry is an important industry in my country's light industry and plays an important role in economic development. my country's textile and clothing production occupies an important position in the world, and the development of textile fabrics will directly affect the development of textile and clothing products. [0003] Textile cloth is the basis for preparing garments and textiles, and its quality index directly affects the finished product. Among the quality indicators of textile fabrics, the pH value is an important indicator required by customers, and it is also an important ecological assessment indicator in the national mandatory standard GB18401-2010 "National Basic Safety ...
