How dyeing machine dyeing can effectively avoid creases

This is very difficult, the industry is called the watermark line, this and the fabric will be stacked when it is stacked, if you want to solve the problem when you stack it under the machine, you must not fold, so that the fabric is in a round shape, you can roll it in the tube, and then you can't fold it after dyeing, and you have to roll it up, but you can't do it in this way, and the watermark crease is allowed in the industry.

Summary. Hello, dear, change the nozzle pressure and the speed of the lifting roller.

Hello, dear, change the nozzle pressure and the speed of the lifting roller.

1.For heavy fabric dyeing, the nozzle pressure of the staring machine should be appropriately increased, and the speed of the lifting roller should be slowed down a little, so as to smoothly promote the normal operation of the fabric; On the contrary, the nozzle pressure needs to be appropriately reduced, and the speed of the lifting roller should be increased to reduce the water flow and the tension between the lifting roller source and the fabric, so as to reduce the crease caused by stretching and hail on the surface of the fabric in the dye vat.

2.The dyeing cylinder must pay attention to the large amount of the cylinder, and generally arrange the production according to the 60 70 of the volume of the manuscript to avoid the crease caused by the poor operation of the fabric in the tank;

3.After terminating the dyeing, you should not smile and be in a hurry to drain the liquid, but should gradually add cold water to the overflow dyeing machine in the operation of the fabric, wash it with flowing water for a while, and then carry the lack of liquid drainage after the temperature of the fabric and the body has dropped, or even change the liquid to clean. If this method is used in the roll hall dyeing machine, it can also reduce the generation of "loose plate printing".

Hot and cold buffers facilitate dyeing processing.

Laboratory dyeing and proofing operationIn the daily production of printing and dyeing factories, there are many factors that affect the color accuracy of finished fabrics, and the accuracy of laboratory proofing is undoubtedly the most important of many factors. It is of great significance to continuously stabilize and improve the accuracy of proofing in the laboratory of printing and dyeing factories to improve the accuracy of color.

The reason for the formation of color flowers and creases by dyeing and proofing.

1. The cloth surface contains acid or alkaline: the cloth used in the laboratory is taken from the workshop, and it happens that the acid and alkalinity are not clean, and even some of the cloth used for color testing is simply refined and desizing by hand, and the slurry and acid and alkali are not completely removed; Blocks with high alkalinity absorb the reactive dye rapidly, and the concentration is deeper in this area and shallower in other blocks. For nylon, the color rate of blocks with high alkalinity will be poor.

Human hand sweat also has acidic or alkaline sweat, and after touching the cloth surface, if the dye sensitive to acid and alkali will cause uneven color. Therefore, how to prevent the surface of the cloth from being acidic or alkaline, that is, boiled with water.

2. The penetration problem of cloth: because the amount of water in the dyeing solution is very small, the cloth may not be fully immersed in the dyeing solution, so the cloth should be quickly shaken and stirred after being put into the dyeing cup to evenly distribute the dyeing solution on the cloth surface, and then quickly inserted into the dyeing machine, and after inserting the dyeing machine, the dyeing machine should be rotated, and the above action is to let the dyeing liquid flow evenly through the cloth surface, once stopped, the penetration into the dyeing area is particularly good, so the color of the block with particularly good penetration is particularly deep;

3. Dosing: The gold dosing in the reactive dye has miscanthus (Yuanming powder) and alkali, if the dye cup is added in the way of powder, the powder is poured into the cloth surface without direct contact, and it should be fully stirred until it is even, and the machine should be run immediately after the cylinder cup is inserted back; If the soaked solution is added, the machine will be run immediately after the addition, in short, the miscanthus nitrate and alkali can not be stagnant after the addition, the cloth and the dyeing solution must be kept running.

4. Cloth frame: because the dyeing liquid is very small, and the dyeing liquid can run and circulate in all corners at any time, with the traditional way, the amount of dyeing liquid is very large, and the way of throwing the dyeing cloth into the dyeing cup with a ball can not solve the crease caused by accumulation; Be especially careful not only to put it flat, but even to have a cloth frame to prop it up; Cooling down too quickly can also create or crease blemishes; Creases and color blemishes are often two sides of the same coin.

In order to dye the fabric flat, the rotation mode of the cylinder cup of the color test machine has a decisive influence, and the glycerin type is only in two directions, which is easy to crease and color flowers, so the low liquor ratio dyeing is still dominated by the infrared color test machine, which is a 360-degree rotation to show its function better.

At the same time, the infrared color tester has a dosing device, which can avoid color flowers and creases due to dosing action.
