Abstract

The invention discloses a continuous dyeing method and apparatus with quantitative aid adding, which is used to solve the problem that the reaction of two or more chemical ingredients before padding causes unstable quality. The method according to an embodiment of the invention comprises the steps of 1, feeding cloth into a first padding device through a cloth feeder, wherein a dyestuff is received in a trough of the first padding device and at least comprises a dispersive dyestuff, an active dyestuff, an oxygen removal enzyme, a penetrating agent, and a dispersant, and the cloth is padded with the dyestuff in the trough; 2, feeding the cloth into a second padding device after passing through the first padding device, wherein an aid is received in a bucket of the second padding device andat least comprises one or more of a base, water glass, and a cationic softener; 3, feeding the cloth into a continuous steaming device after passing through the second padding device, with heat dryingand color fixation carried out on the cloth; and 4, discharging the cloth from an exit of the continuous steaming device to a product collector which collects the cloth as a finished product.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a continuous dyeing method and equipment for quantitatively applying auxiliary agents. Background technique [0002] In the traditional textile printing and dyeing process, the cloth needs to be pad-dyeed. For example, when continuously pad-dyeing reactive dyes, it is necessary to pad-dye reactive dyes and alkali agents in the same bath; However, it is well known that reactive dyes will decompose when they encounter alkali. If they are in the same bath, it will easily cause the hydrolysis of reactive dyes in the trough, and the color difference between the head and tail of the product will appear. Disperse dyes and alkaline or cationic additives are in the same bath , It will also cause problems such as flocculation, agglomeration, and decomposition. [0003] For a long time, the way to solve this problem in the industry is to seek alkali-resistant reactive dyes at high cost, or ...
