Abstract

The invention discloses a low-temperature high-pressure jet vat dyeing process of wool, which comprises the steps: I, adding water into a dye vat, adding an auxiliary agent, mixing well, and soaking wool in the dye vat for 40-50 minutes; II, adding a dyestuff into the dye vat, mixing well, heating the dye vat to 90 DEG C, and holding the temperature for 30-60 minutes, and increasing the pressure to 0.2-0.25 MPa; III, releasing the pressure of the dye vat to normal pressure, and discharging water after the temperature in the dye vat is reduced to normal temperature, so that high-pressure low-temperature dyeing of the wool is completed. According to the low-temperature high-pressure jet vat dyeing process of wool, alkaline protease is used to pretreat the wool, so that handle of the wool isimproved, dye absorption rate is increased, and color fastness is improved. Pressure is applied in the dyeing process, so that dyeing permeability of wool is improved, dyeing defects caused by bubblesgenerated at high temperature in the dyeing process are avoided, and the dyeing consistency is improved. The alkaline protease is inactivated through high temperature and high pressure, so that the treatment process where the alkaline protease is destroyed by pH acid adjustment is omitted, the time is saved, and the dyeing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to a wool low-temperature, high-pressure cylinder dyeing process. Background technique [0002] There is a hydrophobic dense scale layer on the surface of wool fibers, which hinders the adsorption of dyes to wool fibers and their diffusion into the interior. Therefore, wool dyeing needs to be carried out under high temperature conditions. The dyeing temperature is at a height of 100°C, which can increase the diffusion rate of the dye. However, such a high temperature will also cause a large number of air bubbles in the dyeing vat, which will cause dyeing defects and affect the consistency of dyeing. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: wool low-temperature and high-pressure cylinder dyeing process, including the following steps: [0004] Step 1. Add wate...
