Polyester yarn dyeing device and method

Abstract

The invention discloses a polyester yarn dyeing device and method. The polyester yarn dyeing device comprises polyester yarn, a dyeing mechanism, a washing mechanism and a drying mechanism; the washing mechanism and the drying mechanism are arranged on one side of the dyeing mechanism in sequence, the polyester yarn penetrates through the dyeing mechanism, the washing mechanism and the drying mechanism in sequence, and yarn guide wheels are arranged at the left and right ends of the upper surface of the dyeing mechanism and the left and right ends of the upper surface of the washing mechanismrespectively. According to the polyester yarn dyeing device and method, the polyester yarn is subjected to flow dyeing through the yarn guide wheels and dyeing guide wheels of the dyeing mechanism, surface dye of the polyester yarn is washed through the washing mechanism, finally, the polyester yarn is dried through the drying mechanism, and thus flow dyeing processing of the polyester yarn is achieved; no repeated dyeing operation is needed, and time and labor are saved; meanwhile, extruding rollers extrude out redundant dye carried by the polyester yarn, redundant dye is prevented from beingcarried out, and thus resource waste is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of polyester yarn production, in particular to a polyester yarn dyeing device and a dyeing method thereof. Background technique [0002] Polyester yarn refers to the yarn spun from polyester as raw material. During the production and processing of polyester yarn, some polyester yarns need to be dyed to realize the production of polyester yarn of various colors. [0003] The existing polyester yarn dyeing is to put the wound polyester yarn into the dye tank for dyeing, and this dyeing method needs to repeatedly take out the dyed yarn and put in the undyed yarn, and the dyeing operation is cumbersome , time-consuming and labor-intensive, and this dyeing method is prone to uneven dyeing of the yarn. At the same time, when the dyed yarn is taken out, a large amount of dye will be carried to cause waste of resources, and the depth of dyeing cannot be well adjusted.
