How to reduce the color difference of high-strength polyester yarn? The dyeing color difference of high-strength polyester yarn has always been a big problem! Although it can't be completely solved at present, there are ways to minimize the color difference!

1. Dyestuffs: Select batches of dyes with moderate quotations and do not change dyes frequently.
2. PH value: The dyeing color of the disperse dye is not stable under the condition of pH value of alkali. The pH value is 4.5, and the proportion of ml acid/kg yarn in small cylinder dyeing generally does not reach the required PH value. According to the actual situation, the amount of glacial acid is adjusted, the amount of glacial acid is accurate, and the stable PH value is also a key factor for reducing the cylinder difference.
3, bath ratio: bath ratio should not be too large, after the yarn is full of wet and permeable, high-strength polyester yarn dye water is more than 10 cm of the yarn surface.
4. Material: Accurate material ability to ensure the reproducibility of the return order. When registering the recipe to the material book, the date, the weight of the yarn, and the place of origin should be written. When the order is returned, the color is wrong. Write the condition of each feeding on the paper. Then paste the material as a reference for the adjustment formula. After obtaining the accurate formula, sometimes the error is not changed after the return of the single order. When dyeing the new cylinder, it is best to register the sample recipe on the material. It has not been used for a long time. When the formula returns to the order, it should be repeated. When the new board is dyed, the color is washed and the size is different. It is necessary to re-apply in time to avoid the need to feed the next time.
5, heating rate: try to rate the common. Make sure that the boiler has sufficient pressure for steam supply. The high-strength polyester yarn will heat up for too long, and the color error will be fierce.
6. Dyeing liquid flow: Select the dyeing tank with common flow.
7. Operational aspects: The high-strength polyester thread needs the operator to carefully and carefully operate according to the process requirements. The weighing room and the weighing platform and the weighing bowl are clean and boring, and the accurate electronic scale is used to ensure the accurate weighing. . When a dyeing cylinder is dyed for a long time, it will condense a layer of impurities in the cylinder, and then it will be affected by the light color. Constantly summarizing and stacking experiences, and reducing the cylinder difference to a minimum.
