What are the requirements of GQY Air-Liquid Dyeing Machine for dyes?

As an advanced dyeing equipment, GQY Air-Liquid Dyeing Machine has specific requirements for dyes with its unique gas-liquid dyeing technology to ensure efficient and high-quality dyeing effects.
1. Solubility of dyes
Since the machine adopts gas-liquid mixed dyeing, the dyes need to have good water solubility or be quickly and evenly dispersed in the dye liquid under the action of specific auxiliaries. If the dye solubility is poor, it may cause the dye to fail to fully reach the surface of the fabric fiber with the air and liquid flow during the gas-liquid injection process, resulting in local insufficient dyeing or color flower phenomenon.
2. Stability of dyes
During the dyeing process, the machine will experience changes in temperature, pressure, and rapid circulation of gas and liquid. The dye should be able to maintain a stable chemical structure under these complex working conditions without decomposition, discoloration or coagulation. For example, some high-temperature disperse dyes must ensure that their molecular structure is not destroyed during the high-temperature dyeing stage of the GQY dyeing machine to ensure the accuracy and consistency of the dyeing color. If the dye has poor stability, it will not only cause the dyeing color to deviate from expectations, but may also reduce the dye uptake and color fastness of the dye, causing the fabric to fade easily during subsequent use.
3. Compatibility of dyes and auxiliaries
The dyeing process of the GQY dyeing machine may use a variety of auxiliaries to adjust the pH, surface tension, levelness and other properties of the dye solution. The dye needs to work well with these auxiliaries and work synergistically to optimize the dyeing process. Otherwise, it may cause uneven dyeing of the fabric, color difference problems, and fail to meet the requirements of high-quality dyeing.
4. Environmental protection and cost
The low pollution and high utilization rate of the dye are also expected by this dyeing machine. Choosing environmentally friendly dyes, such as dyes that meet relevant environmental standards and have good biodegradability, can help reduce the wastewater treatment burden and environmental impact during the dyeing process. At the same time, dyes with high dye uptake can reduce the amount of dyes used, reduce production costs, and improve production efficiency and economic benefits while ensuring the dyeing effect.
