Problems solved by technology

The existing underwear dip-dyeing process generally uses the dyed material to move back and forth to achieve the effect of relative movement between the dyed matter and the dyestuff, which is difficult to operate and often causes problems such as damage to the dyed matter and uneven printing and dyeing, which is not conducive to low-cost and high-efficiency dip-dyeing.

Description

technical field [0001] The invention relates to the technical field of dip-dyeing, in particular to a dip-dyeing method for underwear. Background technique [0002] Exhaust dyeing, also known as exhaust dyeing, is an application term for dyes. The method of immersing the dyed object in a dye bath containing dyes and required auxiliaries, and gradually dyeing the dyed object with the dye through the circulation of the dye bath or the movement of the dyed object. A dyeing method in which the fabric is repeatedly dipped in the dye solution to keep it moving relative to the dye solution. The existing underwear dip-dyeing process generally uses the dyed matter to move back and forth to achieve the effect of relative movement between the dyed matter and the dyestuff, which is difficult to operate and often causes problems such as damage to the dyed matter and uneven printing and dyeing, which is not conducive to low-cost and high-efficiency dip-dyeing.
