\n Therefore, you should choose a dye with moderate water solubility, small particles, uniform diffusion, and few impurities;<\/p<\/p>\n
\n At the same time, the amount of salt should be reduced as much as possible and the salt should be added slowly in batches;<\/p<\/p>\n
\n The color should be checked before adding alkali. When using soda ash as the fixing agent, the adding time should not be too long;<\/p<\/p>\n
\n And use additives that can help dissolve, diffuse and slow adsorption;<\/p<\/p>\n

\n 1. From the perspective of dyes, the amount of dye, the number of water-soluble groups in the dye (that is, the solubility of the dye), the quality of the filling aids (diffusing agent, salt content, co-solvent) in the dye, and the dye manufacturing process The size of the molecular particles has a great impact on the dissolution, diffusion and leveling of dyes. \ufffd<\/p<\/p>\n

However, high directness will cause difficulty in leveling dyeing and color flowers. At the same time, high directness will also cause Defects such as unstable shade and poor color fastness. Subsequent soaping will further affect the shade and fastness. On the other hand, due to the large molecular groups of active emerald blue, with water-soluble groups generally around 3.5, its solubility is poor and molecules easily associate with each other to form color stains; especially in neutral electrolytes In the presence of dye, the solubility and diffusion performance of the dye will be further reduced, and the dye will precipitate in the form of multiple molecular associations, causing obvious color stains.. <\/p>\n

\n Although the parent material of reactive turquoise blue dye is the same, due to the different additives, dispersants, sulfonation temperature and other factors used by different manufacturers in production, the performance of reactive turquoise blue dye is different. Choose one with moderate solubility, small particles, and Dyes that are easy to spread evenly and have few impurities are crucial to the use of reactive turquoise blue \ufffd<br style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;" \/

Being hindered, it can drive the reactive emerald blue dye molecules to spread evenly in the aqueous solution and play a role in promoting dyeing; however, as the Na+ content further increases, the dye diffusion performance will decrease, it will not be easy to disperse evenly, and it will easily salt out to form stains and flowers. \ufffd\u56e0\u6b64\uff0c\u542b\u6709Na\uff0b\u7684\u5143\u660e\u7c89\u7684\u7528\u6cd5\u548c\u7528\u91cf\u5bf9\u6d3b\u6027\u7fe0\u84dd\u67d3\u6599\u7684\u67d3\u8272\u6781\u5176\u91cd\u8981\ufffd \ufffd<\/p<\/p>\n
