Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0019] This embodiment provides a yarn dyeing process, the dyeing process steps are as follows:

[0020] Step 1: placing the yarn on the loosening bobbin to loosen the yarn;

[0021] Step 2: bleaching the finished yarn of loose yarn;

[0022] Step 3: cooking the bleached yarn, and adding a loosening agent during cooking;

[0023] Step 4: Send the boiled yarn into the dyeing barrel for initial dyeing;

[0024] Step 5: Heat and dry the yarn after primary dyeing in a heating box;

[0025] Step 6: Place the dried yarn on the yarn feeding drum for secondary loosening;

[0026] Step 7: Send the yarn after the secondary loosening into the fine dyeing barrel for fine dyeing;

[0027] Step 8:...

Abstract

The invention provides a dyeing treatment process for yarns. According to the invention, yarns are dyed through secondary dyeing and the colors of the yarns are fixed by a dye-fixing agent so as to improve the color fastness of the yarns; and warping, bleaching, loosing, primary dyeing, drying, secondary loosing, refined dyeing, fixing and packaging are successively carried out for dyeing of the yarns, so color fastness in yarn dyeing is improved, the yarns are not prone to fading after long-term use, and the service life of the yarns is prolonged.

Description

technical field [0001] The invention relates to the field of yarn dyeing, in particular to a yarn dyeing process. Background technique [0002] At present, when dyeing yarn, the yarn is usually dyed by dip-dyeing the yarn once or twice, but the color fastness of the yarn is not high after dyeing the yarn in the above-mentioned way, and the yarn after long-term use The color will fade and affect the use of the yarn. Therefore, it is particularly important to solve the problem of insufficient color fastness and easy fading of yarn after dyeing. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a yarn dyeing treatment process, which dyes the yarn through secondary dyeing, and fixes the color of the yarn through a color-fixing liquid, so as to improve the color of the yarn. Color fastness solves the problem of insufficient color fastness and easy fading of yarn after dyeing...
