Embodiment Construction

[0018] The present invention will be described below in conjunction with specific embodiments.

[0019] The polyester continuous on-line dyeing process includes the following process steps, specifically:

[0020] a. The polyester fiber material is continuously conveyed into the dyeing box through the aluminum belt conveyor line of the dyeing box, and the spray pipe in the dyeing box sprays the dye color liquid from top to bottom to the polyester fiber material on the aluminum belt conveyor line of the dyeing box , the polyester fiber material is polyester tow or polyester staple fiber;

[0021] b. The polyester fiber material sprayed with the dye color liquid is transported to the steam box through the aluminum belt conveyor line of the dyeing box, and the net laying device in the steam box will lay the polyester fiber material sent out by the aluminum belt conveyor line of the dye box, and lay the net The final polyester fiber material falls into the steam box aluminum belt ...

Abstract

The invention discloses a continuous online polyester dyeing process. The process includes the following steps that 1, polyester fiber is continuously conveyed into a dyeing box for spraying dyeing through a dyeing box aluminum belt conveying line; 2, the polyester fiber sprayed with dye liquor is conveyed into a steaming box and then is laid on a steaming box aluminum belt conveying line througha lapping device, and a steam spraying pipe is arranged above the second half of the steaming box aluminum belt conveying line in the steaming box and sprays steam with temperature of 98 DEG C to a polyester fiber web; 3, the polyester fiber web obtained after steam spraying is conveyed into a soaping box, and the soaping box sprays a soaping agent to the polyester fiber web through a spraying pipe; 4, the soaped polyester fiber web is conveyed into a washing box for washing; 5, the washed polyester fiber web is conveyed into an oiling box and sprayed with spinning oil. By means of the process, the color consistency in polyester dyeing can be effectively guaranteed, and continuous polyester dyeing can be efficiently achieved.

Description

technical field [0001] The invention relates to the technical field of polyester processing, in particular to a continuous on-line polyester dyeing process. Background technique [0002] In the prior art, the polyester fiber material is usually dyed by being placed in a dye vat before spinning. [0003] In addition, in the process of dyeing polyester fiber materials through dyeing vats, the dyeing efficiency is low, and it is difficult to ensure that different batches of dyeing can ensure consistent colors. Contents of the invention [0004] The object of the present invention is to provide a polyester continuous on-line dyeing process for the deficiencies of the prior art. The polyester continuous on-line dyeing process can effectively ensure the consistency of polyester dyeing color, and can efficiently realize the polyester continuous dyeing process. [0005] In order to achieve the above object, the present invention is achieved through the following technical solutio...
