The Knowledge of Textile Dyeing

Textile dyeing can be done at any stage, for example, fiber, yarns, fabrics and garments can all be dyed at different stages.

The bulk fiber dyeing: Put the bulk fiber into a large dye jar and dye the bulk fiber at the appropriate temperature, usually adopting the low temperature dyeing process. The advantage of loose fiber dyeing is that it is energy-efficient and has a high dying rate in the dyeing process .Moreover, by a number of spinning processes; it makes the color of fiber gentler than before.

Skein dyeing: It is one of the most expensive dyeing methods that putting the loose hank yarn into the special dye jar. The advantage of hank yarn dyeing is the short cycle, the fast delivery and the bright color. However, it can only be applied to the solid color. If need the melange yarn, could only choose the bulk fiber dyeing.

Dye selection: We choose the reactive dyes, of which the characteristic are simple molecular structure, bright color, complete color spectrum, low cost, good water solubility, good dispersion and good levelness, high washing color fastness and rubbing fastness.

Low temperature dyeing process: Conventional dyeing of wool with reactive dyes is carried out in boiling or nearly boiling dyeing bath. This dyeing method will greatly damage wool fibers, resulting in the fabric strength reducing, feeling it rough and the short fiber increasing.

Cashmere & wool dyeing: Cashmere fibers, like our hair, are both the protein fibers. If we dye it in high temperature dyeing process, its strength will reduce and it feels rough. Therefore, the low temperature dyeing process should be applied to the cashmere dyeing, and it is also suitable for wool dyeing, which makes sure to keep the cashmere native characteristic .
