In the textile dyeing and finishing process, the problem of water quality and impurities often directly affects the stability of the process and the dyeing quality. Calcium and magnesium ions in hard water, as well as rust and impurity deposition in the equipment pipelines, are very easy to react with dyes or auxiliaries, leading to problems such as dye precipitation, dyeing defects, color spots, and equipment scaling etc. These quality risks not only increase the risk of rework, but also cause waste of energy resources.
To solve this pain point, the textile industry widely applies sequestering and dispersing agents, which can efficiently complex metal ions in water and disperse and stabilize impurities so as to prevent sedimentation or agglomeration. With the environmental protection policy becoming stricter, phosphorus-free and nitrogen-free sequestering and dispersing agents have gradually become the first choice in the international market.
Action Principle of Sequestering & Dispersing Agent
Sequestering & Dispersing Agent forms a stable complex compound with metal ions such as calcium, magnesium and iron ions through polycarboxyl groups or other functional groups in the molecule to block the reaction between metal ions and dyes or auxiliaries. Meanwhile, its dispersing function can stably suspend the dirt particles in the bath to prevent their sedimentation or coagulation.
So that it can achieve effects as follows:
- Softens water and improves the stability of the dyeing and finishing process.
- Reduces dyeing defects and color spots and ensures fabrics are dyed evenly.
- Prevents equipment scaling and extends the service life of equipment.
- Improves the solubility and stability of dyes. Especially suitable for reactive dyes and disperse dyes.
Sequestering & Dispersing Agent Application
Application Advantage
