Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] Such as figure 1 Shown, a kind of yarn dyeing process comprises the following steps carried out in sequence:

[0056]① Desizing, the formed yarn is unwound through the unwinding mechanism and transported to the desizing tank for soaking. The liquid temperature in the desizing tank is kept at 80°-90°, and the soaking time is kept at 20-60 minutes; The yarn is subjected to ultrasonic vibration to remove the pulp on the yarn;

[0057] ②Water washing once to clean the desized yarn;

[0058] ③ One-time drying, drying the yarn that has been washed once;

[0059] ④Frictional static electricity, choose a suitable material to contact and friction with the yarn to make the yarn carry charges;

[0060] ⑤Initial dyeing, the dye is atomized and sprayed to the surface of the yarn through the atomization device to dye, the temperature of the dye ...

Abstract

The invention relates to a dyeing technology of yarn. The dyeing technology comprises the sequential steps as follows: (1) desizing: formed yarn is removed through a backing-off mechanism and conveyedto a desizing tank for wetting, wherein the liquid temperature in the desizing tank is kept at 80-90 DEG C and the wetting time is kept for 20-60 min; then, the yarn is subjected to ultrasonic oscillation through ultrasonic waves and size skin on the yarn is removed; (2) primary washing: the desized yarn is cleaned; (3) primary drying: the primarily washed yarn is dried; (4) friction static electricity: a proper material is selected to make contact with the yarn, so that the yarn is charged; (5) primary dyeing: dye is atomized and sprayed to the surface of the yarn through an atomization device for dyeing at the dye temperature of 60-90 DEG C for 2-5 min; (6) secondary dyeing: dye is atomized and sprayed to the surface of the yarn through the atomization device for dyeing at the dye temperature of 90-110 DEG C for 2-5 min; (7) secondary washing: the dyed yarn is washed; (8) neutralization: acetic acid is used for neutralization.

Description

technical field [0001] The invention relates to a yarn dyeing process and belongs to the textile field. Background technique [0002] In the production process of textiles, the stage at which dyeing is carried out is affected by several factors. From an economic point of view, dyeing is carried out at the front of the weaving production process, and its cost is the lowest. For yarn dyeing in the pre-weaving process, dyes with better fastness can be selected, and some colored patterns can be improved in the subsequent weaving process. Yarn dyeing can generally achieve a good and firm level dyeing effect, and can be woven with natural yarns according to different design requirements, thereby obtaining higher economic value and shortening the delivery cycle, so the product has high reproducibility. [0003] It is generally believed that the products obtained by dyeing yarns have the advantages of bulkiness and fullness compared with products obtained by dyeing fabrics, which ...
