Embodiment 2

[0036] A yarn with high colorability is provided. The only difference from Example 1 is that the bath ratio in the dyeing process is 1:8, the dyeing temperature is 120°C, and the rest are the same as those in Example 1.

Embodiment 3

[0038] Provide a kind of high coloring yarn, obtained by the following process:

[0039] S1. Pretreatment: scouring the pure cotton yarn to remove most of the impurities on its surface, then drying the yarn, and then passing through a low-temperature plasma generator. In an oxygen environment, set the power of the plasma generator to 75W and the pressure 30Pa, low temperature plasma treatment for 5min;

[0040] S2. After the low-temperature plasma treatment, the yarn is dyed and dyed. The dyeing bath ratio is controlled to be 1:7.5. First, the yarn is soaked and dyed in the dye solution at 40 °C for 3 minutes. ℃, heat preservation for 15min, and finally the dye liquor is heated to 120℃ for 2min, the heating rate of the whole process is 5℃ / min;

[0041]S3. After the yarn is dyed, it is removed from the dye liquor, steam-fixed for 4 minutes at 150°C and a steam pressure of 0.55MPa, then washed with water at 30°C for 5 minutes, and dried at 105°C for 6 minutes , to complete the...

[0043] Provide a kind of high coloring yarn, obtained by the following process:

[0044] S1. Pretreatment: scouring the pure cotton yarn to remove most of the impurities on its surface, then drying the yarn, and then passing through a low-temperature plasma generator. In an oxygen environment, set the power of the plasma generator to 75W and the pressure 30Pa, low temperature plasma treatment for 5min;

[0045] S2. After the low-temperature plasma treatment, the yarn is dyed and dyed. The dyeing bath ratio is controlled to be 1:5.5. First, the yarn is soaked and dyed at 50 °C for 5 minutes, then the dye solution is heated to 75 °C and then incubated for 6 minutes. ℃, heat preservation for 18min, and finally the dye solution is heated to 120℃ for 2min, the heating rate of the whole process is 6℃ / min;

[0046] S3. After the yarn is dyed, it is removed from the dye liquor, steam-fixed for 4 minutes at 150°C and a steam pressure of 0.55MPa, then washed with water at 30°C for 5 mi...

Abstract

The invention relates to a yarn dyeing process and high-dyeing-property yarn, and relates to the field of textile fabric dyeing, the yarn dyeing process comprises the following steps: S1, pretreatment: boiling off the yarn, washing with water and drying after boiling off, and then carrying out low-temperature plasma treatment on the yarn; s2, dyeing: immersing the yarns subjected to low-temperature plasma treatment into dye liquor, controlling the bath ratio to be 1: (2-8), and dyeing the yarns at the temperature of 35-120 DEG C; and S3, fixation: carrying out steam fixation treatment on the dyed yarns, and washing and drying the yarns after the fixation treatment is completed, so as to complete the yarn dyeing process. According to the technical scheme provided by the invention, the yarn dyeing quality and efficiency can be effectively improved, and the dyed yarn has higher color fastness and better quality.

Description

technical field [0001] The present application relates to the field of textile dyeing technology, in particular to a yarn dyeing process and a yarn with high colorability. Background technique [0002] In the field of textiles, dyeing refers to the coloring of the yarn or the textile itself by chemical or other methods. Under the conditions allowed by technology, the textile can be dyed to show the various colors that people need. Different colors enrich the color and expressiveness of fabrics, providing people with more diverse color choices. [0003] Yarn dyeing is a dyeing process with yarn as the object. In the production process of textiles, dyeing is carried out at that stage and is affected by many factors. Generally speaking, the cost of dyeing at the front of the weaving process is the lowest, and dyes with better fastness can be selected, and some designs can be improved in the subsequent manufacturing process. Yarn dyeing can generally achieve better leveling e...
