Embodiment Construction

[0022] The invention proposes a warp beam dyeing process of flax yarn, comprising: loose warping,

[0023] The three processes of dyeing and sizing are completed.

[0024] Loose warping is to loosely warp pure linen yarn through loose warping machine. 460~490g / m 3 .

[0025] In the loose warping process, the temperature in the workshop is controlled at 60%~80% in summer and 40%~60% in winter. If the humidity is relatively biased, adjust the line speed and warp roller pressure appropriately; The setting is 2.5mm. At the same time, the softness and hardness of the loose shaft and the edge of the loose shaft should be felt after the first shaft starts 400~5000m. The same cylinder loose shaft should ensure the same pressure and speed, and the same batch size of the bobbins. Because flax yarn is more expensive, in order to reduce excessive waste during sizing, it is necessary to use ordinary low-grade cotton yarn as a lining before loose warping (that is, first warp 100-150M wit...

Abstract

The invention proposes a flax warp beam dyeing process, which includes three processes of loose warping, dyeing and sizing; wherein, the dyeing process includes pretreatment, dyeing and posttreatment, wherein the dyeing is based on the dyeing depth of the flax yarn Make different adjustments. The beneficial effects of the present invention are: the flax yarn dyeing process of the present invention is completed through three processes of warping, dyeing and sizing, which is related to the prior art. The process structure is reasonable, and the color of the product can be guaranteed through beam dyeing. The consistency ensures the quality of the product. At the same time, it reduces the related operating procedures, thereby saving the production cost and improving the dyeing efficiency. Moreover, the operation is convenient, the product quality is high, and the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a beam dyeing process of flax yarn. Background technique [0002] Linen is a natural plant fiber, which has a certain moisture absorption and perspiration effect. In summer, sweating will not stick to the skin, and it has a breathable and cool effect. Linen also does not encourage bacterial growth due to its smooth surface fibers. With the improvement of people's living standards, linen fabrics are becoming more and more popular. [0003] The crystalline area of ​​flax is as high as 70%, 50% of tension-free mercerized cotton, and 40% of viscose fiber. The intersection angle between fibril and fiber axis is less than 10°, while cotton fiber is 20-25°; The region is larger than the amorphous region, allowing the dye molecules to occupy a small space during dyeing, and the high degree of orientation makes the fiber rigid and hinders the penetration of dye molecules. [000...
