Abstract

The invention relates to a staining method of diacetate fiber deep colors. The staining method comprises the following staining steps of entering a cylinder of diacetate fiber or fabric, adding water to adjust a bath ratio, heating (1), adding staining assistants and dyes, heating (2), insulating (1), overflowing and cooling, cleaning, adding water to adjust the bath ratio, heating (1), adding post-processing assistants, heating (3), insulating (2), overflowing and cooling, cleaning, emptying the water and letting out of the cylinder. Two dyes of disperse dyes and cationic dyes with different properties are adopted to stain, and the staining method of simultaneous staining in the same cylinder by using a one-bath process is adopted, so that the technical problems of non-deep colors by adopting the disperse dyes or only light colors by adopting the cationic dyes are solved, the diacetate fiber can be stained to deep colors such as navy blue, black and the like, and additionally, the production quality requirements of color fastness, spinning and the like are satisfied.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a deep-color dyeing method for diacetate fibers. technical background [0002] Diacetate fiber, soft and smooth to the touch, soft and elegant luster, bright and bright color, good drapability, elasticity, not easy to wrinkle, stable size, good hygroscopicity, moisture regain up to 6%, it is similar to natural silk among chemical fibers It is an excellent fiber raw material for textile production of clothing underwear, children's clothing, fashion, leisure, suits, dresses, etc. [0003] However, due to the structural properties of diacetate fibers, it is difficult to dye deep colors. Contents of the invention [0004] The technical problem to be solved by this invention is to provide a kind of dyeing method of diacetate fiber dark color, by [0005] This dyeing method can dye diacetate fibers of black and other deep colors. [0006] In order to solve the above techn...
