Abstract

The invention provides a dyeing system which comprises a dyeing tank and a mixing barrel which are connected, the dyeing tank is horizontally arranged, a mounting hole plate is arranged in the dyeing tank and divides the dyeing tank into a first cavity and a second cavity, and a positioning assembly for positioning a cloth roll is arranged in the first cavity; a booster pump is arranged between the mixing barrel and the second cavity, the booster pump pumps liquid in the mixing barrel and then pumps the liquid into a first heat exchanger arranged in the second cavity, and the first heat exchanger guides the liquid into the cloth roll; and a circulation assembly forming circulation with the first cavity and the second cavity is further arranged outside the dyeing tank, a second heat exchanger is arranged in the circulation assembly, and liquid in the first cavity enters the circulation assembly, then is heated by the second heat exchanger, enters the first heat exchanger and then enters the cloth roll. According to the dyeing system, the non-woven fabric can be dyed only through one-time operation, the efficiency is high, meanwhile, the dyeing rate of the dyed non-woven fabric can reach 90% or above, and the color fixation rate can reach 90% or above.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric dyeing equipment, in particular to a dyeing system and a dyeing method. Background technique [0002] In the prior art, the pre-dyeing process is generally adopted, that is, dyeing is carried out before the non-woven fabric is made, which easily causes small colored fibers to remain in the non-woven fabric processing equipment, and these small colored fibers are difficult to clean. During the processing of the next batch of non-woven fabrics, the fine colored fibers will affect the processed non-woven fabrics, resulting in the presence of color defects in the latter batch of non-woven fabrics. [0003] When the post-dyeing process is adopted, the prepared dye solution is generally loaded in the dye vat, and then the non-woven fabric is continuously entered and exported from the dye vat to complete dyeing, but the color quality of the non-woven fabric after such dyeing process is not up to...
