Technical Field

The invention relates to the technical field of textile printing and dyeing, in particular to a homogenizing dyeing device and a dyeing method for natural plant source antibacterial knitted fabric.

Background

The two cloth dyeing processing technologies are generally adopted, namely coating dyeing and dip dyeing, and the dip dyeing mode has large pollution and wastes materials. To dip-dyeing, mostly soak the cloth in the dye vat, the manual stirring dyestuff makes the cloth evenly color, then takes out the cloth after will dyeing and dries, not only makes the cloth fold and overlap the department and make the dyestuff detain easily like this, leads to the cloth to dye inhomogeneously, and work efficiency is low. Meanwhile, the adsorption of the cloth on the dye is a reversible process, the adsorption and desorption are repeatedly carried out, and after the dye is adsorbed on the surface of the fiber, a dye concentration difference is formed between the inside and the outside of the fiber, wherein the adsorption is fast and the desorption is slow in the initial dyeing stage; the adsorption gradually becomes slow along with dyeing, and the desorption becomes fast; until equilibrium is reached. In the dyeing process, the dye in the dye vat is fixed, if the dye is too much, waste is easy to cause, and if the dye is too little, the coloring effect is relatively poor.

Also have the mode that adopts direct spray-painting, when adding the coloring agent, the shower sprays and on the fabric surface easy bubbling, and it is in disorder that the cotton fibre appears more easily that the bubbly fabric carries out subsequent processing, and the woollen on current cloth surface is more moreover, and the unclean quality that can influence whole cloth has reduced the holistic aesthetic feeling of cloth.
