Description

Technical Field

[0001] The invention relates to the field of dyeing, in particular to a dyeing process for cotton yarn. Background Art

[0002] Dyeing, also known as coloring, refers to the process of coloring a substance by chemical or physical means. Where technology permits, dyeing can produce a wide variety of desired colors, adding a touch of brilliance to everyday life. Yarn is a product made from various textile fibers processed to a specific fineness. Dyeing yarn and then weaving it creates woven products with richer patterns. Yarn dyeing methods primarily include beam dyeing, hank dyeing, cheese dyeing, compressed cheese dyeing, and packing dyeing, among other uniform dyeing processes.

[0003] Chinese patent CN111235788A discloses a textile yarn dyeing process, including the steps of wiring, dyeing, drying, winding, and thread cutting. In the dyeing mechanism, a first electric slider drives a rotating plate to rotate along a circular track to keep the dye liquid in a flowing state; in the drying mechanism, a second electric slider drives a hollow tube to rotate back and forth, and the hollow tube drives an electric heating plate to rotate synchronously. The electric heating plate is powered to dry the dyed yarn. However, this dyeing process, which drives the rotating plate to cause the dye liquid to flow in the hope of solving the problem of uneven dye liquid stratification, is not only complex in structure and has a relatively poor mixing effect, but also has a low drying efficiency due to the rotation of the electric heating plate for drying, which greatly affects the yarn dyeing efficiency.
