[0003] However, the existing bamboo pulp viscose fiber has low wet strength and small modulus, and has weaknesses such as easy deformation and poor shape retention in the wet state. The fabric surface color produced by the existing dyeing process is not uniform and full, and the dyeing reproduction Poor performance, poor stability, need to add a lot of salt, poor permeability, low color fixation rate, and will produce a lot of waste liquid. In the existing process, caustic soda / water glass mixed alkali agent is usually used, which will greatly affect the fabric. Hand feel, making the fabric not soft enough

[0085] The mouth of the fire is positive and negative,
[0086] Bamboo pulp viscose fiber fabric has many and dense hairiness on the surface, and unclean singeing will affect the smoothness of the fabric surface. Cold pad-batch dyeing has stricter requirements for this. Therefore, the singeing process is very critical, and the singeing quality must reach above grade 3-4.

Abstract
The invention discloses a cold pad-batch dyeing process of bamboo pulp viscosefiber fabric. In the production process, the pre-treatment adopts roll cylinder treatment to reduce the tension in the production process, and uses cold pad-batch dyeing process to dye the bamboo pulp viscosefiber fabric during dyeing. The cold pad-batch dyeing process makes the color of the fabric uniform, transparent and full, and the dyeing reproducibility and stability are good. In the finishing process, the hydrophilic softener is used to give the fabric an excellent hand feeling, and at the same time, the fabric's good moisture absorption and air permeability can be fully reflected, making it more comfortable to wear.
Description
technical field [0001] The invention relates to the technical field, in particular to a cold pad-batch dyeing process for bamboo pulp viscosefiber fabrics. Background technique [0002] Bamboo pulp viscose fiber is produced by chemically making bamboo pulp from bamboo, dissolving the pulp to make bamboo pulp viscose solution, and then spinning it by wet spinning. Bamboo pulp viscose fiber has low crystallinity, sparse arrangement of macromolecules and high moisture regain. It belongs to regenerated cellulose fiber similar to ordinary viscose fiber. Because of its special cellulose molecular structure, the cross-section of the fiber is full of elliptical voids, and its hygroscopicity and air permeability far exceed that of cotton fiber. Bamboo pulp viscose fiber has the characteristics of good spinnability, good fiber moisture absorption and moisture permeability, soft hand feeling, good fabric drapability, excellent dyeing performance, and soft luster. Bamboo pulp viscose...
