A The dyeing process takes place in three phases: attachment of the dye molecule to the surface of the fiber, penetration into the intermolecular spaces as well as diffusion through the fiber and orientation (and fixation) along the long chain molecules.
Q What are dyeing auxiliaries?
A Dyeing auxiliaries are defined as chemicals or formulated chemicals which enables a processing operation in dyeing to be carried out more effectively. Dyeing auxiliaries includes dye fixing agents, cationizing agent, dispersing & leveling agents etc.
Q What is exhaustion used with dyeing auxiliaries in textile processing?
A In the exhaustion process attained through the optimal use of dyeing auxiliaries absorbs the dyes and the material comes in contact with the dye liquor. As a result, the rate and extent of dyeing process is determined through dye bath exhaustion. We ensure the eco-friendly auxiliaries are used for exhaust dyeing achieve better properties of the fabric.
It is suitable for general waterproof processing of natural fiber (hair, silk, cotton), polyester-cotton blend, nylon-cotton blend, synthetic fiber (polyester, nylon) and other fabrics.
