Embodiment 1

[0027] Example 1: Please refer to figure 1 , a polyester yarn dyeing process, a polyester yarn dyeing process, comprising the following steps: making cheese, cleaning treatment, pre-setting treatment, dye liquor configuration, dyeing, reduction cleaning, washing, dehydration, drying; specifically:

[0028] (1) Production of bobbins: including loose yarns and cages, the tight bobbins are rewound into loose bobbins with a winding density of 0.32g / cm3 through a spinning machine, which can effectively prevent the phenomenon of dyeing during dyeing and eliminate The internal and external color difference ensures smooth dyeing, and the appearance of the original gray yarn can also be inspected during the loosening process. Install the loose bobbin on the sarong as required for dyeing. When loading the bobbin from bottom to top, the small opening faces upwards and the large opening faces downward. The sleeve can be loaded into the tube; when loading the cage, the tube should be hand...

Embodiment 2

[0041] Example 2: Please refer to figure 1 , a polyester yarn dyeing process, a polyester yarn dyeing process, comprising the following steps: making cheese, cleaning treatment, pre-setting treatment, configuring dye liquor, dyeing, reduction cleaning, washing, dehydration, drying; specifically:

[0042] (1) Production of bobbin yarn: including loose yarn and cage loading, the tight bobbin yarn is rewound into a loose bobbin with a winding density of 0.34g / cm3 through a loose yarn machine, which can effectively prevent the phenomenon of dyeing during dyeing and eliminate The internal and external color difference ensures smooth dyeing, and the appearance of the original gray yarn can also be inspected during the loosening process. Install the loose bobbin on the sarong as required for dyeing. When loading the bobbin from bottom to top, the small opening faces upwards and the large opening faces downward. The sleeve can be loaded into the tube; when loading the cage, the tube ...

Embodiment 3

[0055] Example 3: Please refer to figure 1 , a polyester yarn dyeing process, a polyester yarn dyeing process, comprising the following steps: making cheese, cleaning treatment, pre-setting treatment, configuring dye liquor, dyeing, reduction cleaning, washing, dehydration, drying; specifically:

[0056] (1) Production of bobbins: including loose yarns and cages, rewinding the tight bobbins through the loosening machine into loose bobbins with a winding density of 0.36g / cm3, which can effectively prevent the phenomenon of dyeing during dyeing and eliminate The internal and external color difference ensures smooth dyeing, and the appearance of the original gray yarn can also be inspected during the loosening process. Install the loose bobbin on the sarong as required for dyeing. When loading the bobbin from bottom to top, the small opening faces upwards and the large opening faces downward. The sleeve can be loaded into the tube; when loading the cage, the tube should be handl...

Abstract

The invention discloses a polyester yarn dyeing technology which comprises the following steps of preparation of cheese, cleaning treatment, presetting treatment, preparation of dye liquor, dyeing, reduction cleaning, washing, dehydration and drying, wherein the step of presetting treatment is to put the cheese after cleaning treatment in boiling water for treatment for 12-15 min; the step of preparation of the cheese comprises yarn loosening and caging, wherein the coiling density of polyester yarns after being loosened is 0.32-0.36 g/cm<3>; and the step of cleaning treatment is to immerse the polyester yarns into a light alkali solution, perform treatment for 10 min under the condition with the temperature being 100 DEG C and add 1 g/L soaping agent to perform deoiling treatment. In thepolyester yarn dyeing technology provided by the invention, presetting treatment is performed on the polyester yarns before dyeing, and after presetting treatment, the polyester yarns cannot shrink again or shrink slightly when being subjected to high-temperature dyeing as the polyester yarns are shrunk in advance before dyeing, so that polyester yarn fibers uniformly absorb a dye, and the dyeingquality of the polyester yarns is improved.

Description

technical field [0001] The invention relates to the technical field of polyester yarn dyeing, in particular to a polyester yarn dyeing process. Background technique [0002] The dyeing of polyester yarn usually adopts the high temperature and high pressure dyeing method, that is, the polyester yarn is dyed under high temperature and high pressure conditions, and the dyeing temperature can be as high as 130°C. , will cause the fiber to shrink violently, which will affect the uniform absorption of the dye by the polyester yarn fiber, resulting in poor dyeing effect of the polyester yarn. Contents of the invention [0003] The purpose of the present invention is to provide a dyeing process of polyester yarn, aiming to improve the problem of poor dyeing effect of polyester yarn caused by severe fiber shrinkage of polyester yarn in high temperature dyeing solution. [0004] The present invention is realized in this way: a polyester yarn dyeing process, comprising the following...
