Embodiment Construction

[0025] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] The embodiment of the present invention discloses a cashmere fiber dyeing process based on Lanersol dye, comprising the following steps:

[0027] S1. Add the cashmere fiber and the bath liquid to the dye vat, and the bath ratio of the dye liquid is 1:40;

[0028] S2. Raise the temperature to 40°C, adjust the pH value of the dye solution to 6.5, and add the rare earth solution, Abaig B, Yuanmingfen and Lannasol dyes in sequence;

[0029] S3. Gradually heat up the dye liquor, keep the temperature at 95°C, and keep it warm for 60-70min;

[0030] S4. Cool down to 85°C, adjust the pH value of the dye solution to 8.5, and maintain it for 10-15 minutes;

Abstract

The invention discloses a cashmere fiber dyeing process based on a lanasol dye. The cashmere fiber dyeing process comprises the following steps: S1, adding cashmere fibers and a bath liquor to a vat, wherein the bath ratio of the dye liquor is 1: 40; S2, increasing the temperature to 40 DEG C, adjusting the pH value of the dye liquor to 6.5, orderly adding a rare earth solution, Albegal B, anhydrous sodium sulphate and the lanasol dye; S3, gradually heating the dye liquor and preserving heat, keeping the temperature at 95 DEG C and preserving heat for 60-70 min; S4, reducing the temperature to 85 DEG C, adjusting the pH value of the dye liquor to 8.5 and maintaining for 10-15 min; S5, continuously reducing the temperature to the range from 20 to 30 DEG C, and flushing the cashmere fibers to finish dyeing. The cashmere fiber dyeing process provided by the invention is simple and has little harm on the cashmere fibers; the dyed finished product is bright and full in color, good in color fastness and soft in hand feeling. Moreover, rare earth chloride is further added to the dye so as to further improve the dye uptake of the cashmere fibers.

Description

technical field [0001] The invention relates to the technical field of cashmere dyeing, in particular to a cashmere fiber dyeing process based on Lanersol dye. Background technique [0002] The traditional beret is a kind of brimless soft military cap, usually used as a personnel symbol of the Rangers, Special Forces and Airborne Forces of some national armies. The beret has the advantages of being easy to fold, not afraid of being squeezed, easy to carry, and beautiful.
