How Jigger Dyeing Machine improves dyeing
Jan 14, 2022
To improve the dyeing on the Jigger Dyeing Machine and the left, center and right color cast, a very large level lies in the technical mastery of the operator.
Not only must grasp the method of dyeing and chemical melting, sufficient dilution, and be sure to add on the upper and lower sides, after adding, but also use a clean bamboo stick along the side of the tank for 1 to 2 minutes, and stick to the side of the tank. The tap water of the dyestuff is flushed into the main tank.
Strictly control the temperature raising rate when feeding or after feeding. Normally, the main vat fabric will go back and forth two times, and the temperature will be raised by 10-15℃. If the temperature is raised too fast, it is very easy to accelerate the dye uptake rate, and it will not be able to fully exert the effect of the modifier, so that the dyeing and chemical materials absorbed on the fabric are different, especially the dyeing and chemical materials that are more sensitive to temperature, which usually causes comparison. Severe color cast. Therefore, operators should learn and train to work so that they can immediately grasp professional skills and ensure manufacturing.
The operator must grasp the condition of the dye bath in the dyeing machine. For example, in a dye bath dyed with contrast dyes, use a milky white tea bowl to scoop a bowl of water from the dye bath and gradually pour it toward the side of the vat according to the technical unit or the specific number of lines in the production workshop. If there are dark blue or bright red in the remaining liquid, we should find a way to dye them on the fabric, or put salt to promote the dyeing, or add leveling agent to pull it out, depending on the details. Use different chemicals to adjust the color light to achieve the goal of trans-dyeing and reducing color cast.
When printing samples, technical units should choose dyes with a relatively close dyeing rate, or use dyes that are basically the same immediately to contrast the colors, which can improve the compliance rate of the size samples and make it easy for the operators to grasp the dyeing process. , To achieve an excellent dye uptake rate. For color matching, another 5 pieces should be taken for color matching, that is, 1/3 on each side and 2 pieces from the upper and lower sides. Run to the center 1/2 in the management center and then cut 1 piece. If the colors of these 5 pieces are basically the same, the dyeing of this tank of fabric is successful, otherwise, it is necessary to take certain effective measures immediately, or add a certain dye to fill the eyebrows, or increase a certain type of modifier to give level dyeing ( Naturally, all the machinery and equipment are in normal condition).
