Embodiment Construction

[0024] The present invention will be described below in conjunction with specific embodiments.

[0025] The fiber continuous online dyeing process includes the following process steps, specifically:

[0026] a. One-time washing step: Spray normal temperature water on the fiber material by spraying, so as to wash the fiber material;

[0027] B, desulfurization step: by spraying, sodium hydroxide solution is sprayed on the fiber material after a water washing step, to carry out desulfurization treatment to fiber material, the temperature of sodium hydroxide solution is normal temperature, the solubility of sodium hydroxide solution 10g / l-20g / l;

[0028] c, the second washing step: spraying normal temperature water on the fiber material after the desulfurization step by spraying, so as to wash the fiber material after the desulfurization treatment;

[0029] d. Dyeing step: Spray the color liquid on the fiber material after the second water washing step by spraying, so as to rea...

Abstract

The invention discloses a continuous on-line dyeing process for fibers, which comprises the following process steps: a, first-time water washing; b, desulfurization; c, second-time water washing; d, dyeing; e, soaping; f, third-time water washing; and g, oil passing, wherein a fiber material is conveyed through a reducer-driven steel mesh conveyor belt, and passes through a first-time water washing zone, a desulfurization zone, a second-time water washing zone, a dyeing zone, a soaping washing zone, a third-time water washing zone, and an oil passing zone in sequence, so as to be subjected tothe steps of first-time water washing, desulfurization, second-time water washing, dyeing, soaping, third-time water washing and oil passing. Through the process step design above, the continuous on-line dyeing process can effectively ensure the consistency of dyeing colors, and can effectively realize continuous dyeing of the fibers.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a fiber continuous on-line dyeing process. Background technique [0002] In the prior art, fibers, yarns or knitted fabrics are generally dyed in a dye vat during the production process. [0003] In addition, in the process of dyeing fibers, yarns or knitted fabrics through dyeing vats, the dyeing efficiency is low, and it is difficult to ensure that different batches of dyeing can ensure consistent colors. Contents of the invention Contents of the invention [0004] The object of the present invention is to provide a continuous fiber dyeing process on-line, which can effectively ensure the consistency of dyeing color and efficiently realize continuous fiber dyeing processing. [0005] In order to achieve the above object, the present invention is achieved through the following technical solutions. [0006] The fiber continuous online dyeing process includes the following process steps, ...
