Dyeing process of basolan wool

Abstract

The invention discloses a dyeing process of basolan wool, and belongs to the technical field of printing and dyeing. The effective process concretely comprises the following steps: yarn is hanged andplaced in a cylinder; yarn is washing; a reactive dye and an auxiliary agent are added; heating is carried out and dye is uptaken; insulation is carried out and yarn is taken out of the cylinder. Theprocess has the beneficial effects as follows: (1) by means of heating and washing of the yarn, the yarn is soaked, dyeing effects of later dyeing are improved, and the phenomenon of colored spots onthe yarn rarely appears; (2) when the material is added, temperature of clear water is controlled, the phenomenon that the surface of the yarn appears larger color difference or colored spots is reduced, and integral quality and beauty of the basolan wool product are improved; (3) while heating is carried out and dye is uptaken, after the temperature is heated to 85 DEG C, color of dye water is observed, heating speed is properly adjusted, reaction speed is accelerated, and dyeing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and more specifically relates to a dyeing process of Basolan wool. Background technique [0002] Basolan wool refers to wool that has been treated with the Basolan process. It has the advantages of fluffy, soft, bright color, and less damage to fiber strength. [0003] Acid dyes refer to dyes with acid groups that can dye protein fibers and polyamide fibers in acidic, weakly acidic or neutral dyeing baths. Most of the acidic groups are sulfonic acid groups, and a few are carboxyl groups, which are easily soluble in water and ionized in water to become dye anions. at the same time. The molecular structure of the above-mentioned dyes is relatively simple, most of which are monoazo dyes, and a few are disazo dyes. The molecules lack a long conjugated double bond system, and the coplanarity or linearity of the molecular aromatic rings is not strong. Cellulose lacks affinity. ...

AI Technical Summary

Problems solved by technology

When dyeing dark-colored yarn, there is little difference in quality or color difference in the later stage due to the darker color, but when dyeing light-colored yarn, there will be large color lag, color difference or color flower phenomenon on the surface of the yarn. Affects the overall quality and aesthetics of light colored Basolan wool products

[0008] If the water temperature in the dyeing bath is too low when the material is fed, the intermolecular movement will be weakened, making the speed of Basolan wool yarn diffuse or dyed too slow in the early stage, which reduces the efficiency. Scouring will disturb the yarn and affect the overall quality of Basolan wool products
