Color point, color flower 　
cause:
Excessive or premature addition of salt or soda ash will cause dissolved dyes to agglomerate or even precipitate, leading to uniform distribution of the dye on the fabric surface and inside and outside of the fabric, resulting in uneven color, even color spots and stains; reactive yellow is sensitive to alkali In the initial period of alkali addition, the color absorption rate is high, and the color is fixed on the side of the absorption edge, and the migration and dyeing properties are poor. Therefore, it is easy to cause uneven absorption and form color flowers.
Responses:
1. Within the range of conventional dyeing depth, the amount of salt should not exceed 70g/L;
2. Adding sequence: add dyeing auxiliaries (water softener, leveling agent) and take it evenly; warm up to 40-50°C, add the dye solution, fully dissolve; add less salt after several batches. Do not add dyes together with salt or add salt first.
3. Suction time must be sufficient, as much as possible to improve the color absorption rate, in order to reduce the alkali concentration before the dye concentration, is conducive to reducing the degree of dye after the addition of alkali.
4. The amount of soda ash should not be less. Because the soda ash has a strong buffering ability against the pH value, its concentration is between 5 and 25 g/L and the pH value is between 11 and 11.2, which is sufficient to meet the requirements of the dye-fiber binding reaction. Therefore, as long as the depth of the dyed silk is maintained, the pH of the foot water after dyeing can be maintained at approximately 11. Excessive amount of soda ash will increase the tendency of dye aggregation, and active yellow is particularly prominent.
5. The amount of soda ash must be less than the first time and added in batches. This is very important for the activity of green blue and active bright yellow.
Because the active yellow color has a very low color-receiving rate, the concentration of the dye solution is higher before alkali fixation, and adding more soda ash can easily cause dye aggregation and cause quality problems. Reactive yellow is sensitive to alkali. In the initial stage of fixing, the more soda ash is added, the faster the coloration is and the easier it is to color flowers.
6. The dyeing bath can be added 1.5 ~ 2g / L of active leveling agent, such as Shanghai Conton spinning leveling agent L-800 or demulsified leveling agent RG133, can make the dye in saline solution The dissolved state is significantly improved. However, the amount should not be more, otherwise it will reduce the dyeing rate.
Color difference, cylinder difference
cause:
Reactive green blue and active bright yellow have different dependencies on the relevant factors of the dyeing process. Therefore, if the relevant factors of the dyeing process are unreasonable or are not performed according to the dyeing process, it will inevitably lead to instability in the fixation rate of active cyan and active yellow, which will lead to fluctuations in the proportion of blue and yellow dyes on the fiber. , Produce color difference or cylinder difference.
Responses: 　
1. The temperature should be stable at 80 ~ 85 °C. In this temperature range, the color of active cyanine and active yellow is synchronized. the best. Above or below this temperature, the staining reproducibility decreases.
2. The activity of active cyan blue and active yellow is different from that of salt. When the depth of dyeing is around 2% (owf), salt is used. The amount of 50 ~ 60g / L is appropriate. If the amount is too high or too low, the color synchronization of the two will be affected.
3. The concentration of soda directly affects the color fixation rate of active green blue and active yellow (the effect on yellow is greater than that of blue). The amount of soda ash must be strictly controlled, otherwise it will affect the color depth and reduce the reproduction of dyeing. Sex.
4. The dyeing bath ratio has different influence on the activity rate of active turquoise blue and active tender yellow (it has a great influence on the turquoise color). The bath ratio should be strictly controlled to ensure the color depth and color stability.
5. The yellow color of active yellow is much lower than that of active green blue, and the second color-receiving rate is much higher than that of active green blue. Therefore, in different dyeing time periods, the shades and shades of the colors are different. In other words, Reactive Blue and Reactive Yellow are highly dependent on the dyeing time and require special attention.
Therefore, on the basis of achieving the balance of the color absorption in the color-adsorption phase, and then appropriately holding for a certain period of time, it is not only favorable for level dyeing and transfection, but also is conducive to the stabilization of color light. The alkali fixing time should be sufficient to ensure that the active yellow and turquoise blue can achieve a relatively stable maximum color yield. Active turquoise blue is poor in diffusibility, weak in response ability, and lags in yellowish color. Therefore, appropriately lengthening the dyeing time can reduce color and color difference in cylinders.
6. Since the direct activity of active turquoise blue is higher than that of active yellow, and then the washability is relatively poor, it is necessary to strengthen soaping. Weak soaping is not enough or the degree of soaping is not the same, not only will reduce the wet fastness, but also cause a significant cylinder difference.
Poor wet fastness
cause:
The active Cuiras blue has a large molecular weight, lacks a linear structure, and has poor diffusion. Especially in the process of secondary absorption, the adsorption rate of the dye is much higher than the diffusion rate, resulting in the formation of overlapping accumulation of dyes on the fiber surface.
In addition, the reaction of the active turquoise blue is relatively weak, the fixation rate is low, there are many unfixed dyes remaining on the fiber, and the washability is poor, resulting in low wet fastness and poor level dyeing and transfection; due to the activity of bright yellow on alkali The agent is very sensitive. In the initial stage of secondary absorption, the phenomenon of “instantaneous coloration†is serious. In addition, the color is fixed by suction. The fixed dyestuff has a certain retardation on the diffusion of unfixed dyes adsorbed on the fiber surface. Effect, resulting in too much floating color, affecting wet fastness and level dyeing; Active Turquoise Blue and Reactive Brilliant Yellow have poor solubility stability in salt and alkali solutions. Once too much or too early to add salt and soda, it is easy to produce condensation. , Which severely affects the uniform adsorption and uniform diffusion of the dye, excessively early floating color, and decreased color fastness.
Responses:
1. Improve the dissolving state of the dye and prevent the dye in the dye solution from coagulating.
2. Reduce the dye uptake rate during the dyeing process (mainly at the initial stage of alkali addition).
3. Improve the diffusion and dyeing effect of dyes and increase the fixation rate (mainly active turquoise blue).
4. Strengthen soaping after dyeing to reduce the amount of floating dye dyes.

The series centers on the various incarnations of Link, a courageous young Hylian man, with pointy elf-like ears; and Princess Zelda, a magical princess that is the mortal reincarnation of the goddess Hylia; as they fight to save the magical land of Hyrule from Ganon, an evil warlord turned demon king, who is the principal antagonist of the series. Ganon wishes to use the Triforce, a sacred relic left behind by the three goddesses that created Hyrule to remake the world in his own dark image. When gathered together, the power of the Triforce can grant any wish its user desires; however, if someone with a heart that does not possess a balance of the three virtues of Power, Courage and Wisdom attempts to touch the Triforce, it will split into three triangles and bond with three people whose hearts embody the required virtue.
Although their personalities and backstory differ from game to game, the incarnations of Link and Zelda often have many traits in common; such as Link often being left-handed and associated with the color green while Princess Zelda is often a member of the royal family. While the conflict with Ganon serves as a backbone for the series, some games have featured other settings and antagonists, with Link traveling or being sent to these other lands in their time of need.
Since the original Legend of Zelda was released in 1986, the series has expanded to include 19 entries on all of Nintendo's major game consoles, as well as a number of spin-offs. An American animated TV series based on the games aired in 1989 and individual manga adaptations commissioned by Nintendo have been produced in Japan since 1997. The Legend of Zelda is one of Nintendo's most prominent and successful franchises; several of its entries are considered to be among the greatest video games of all time.
