Example Embodiment

[0032] Example one

[0033] A supercritical carbon dioxide dyeing process for aramid / viscose blended fabric. The process flow includes:

[0034] Fabric cleaning pretreatment → fabric low temperature plasma pretreatment → supercritical carbon dioxide dyeing.

[0035] Among them, the pre-cleaning process is: working fluid → hot water washing (80°C) → acetic acid cleaning → cold water rinsing → natural drying → ironing → drying (40°C).

[0036] Among them, the pre-cleaning working fluid prescription is: sodium carbonate 3g / L, JFC 0.5g / L, sodium hydroxide 5g / L.

[0037] Wherein, the plasma treatment includes: putting the fabric to be treated into the treatment chamber of the plasma treatment device, and then evacuating to make the vacuum degree in the treatment chamber less than 3 Pa. Then pass in the working gas. Control a certain treatment time, power and pressure, and perform plasma modification treatment on the fabric.

[0038] Among them, the plasma treatment conditions are: gas mediu...

Abstract

The invention relates to a supercritical carbon dioxide dyeing technology for low-temperature-plasma pretreatment of aramid fiber/viscose glue blended fabric. The technology employs supercritical CO2 as a medium to dye fabric, and is a novel waterless dyeing technology. Compared with conventional dyeing methods, the technology has the advantages of water saving, environment protection, energy saving, dispensing with auxiliary agents and the like, is short in dyeing time, and is capable of shortening production period and improving economic benefit.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a supercritical carbon dioxide dyeing process for low-temperature plasma pretreatment of aramid / viscose blended fabrics. Background technique [0002] Water is a very important medium in the traditional dyeing process. Water is used to wet and swell fibers, and water is used as a solvent, dispersant or dye carrier. After dyeing, cleaning and other follow-up work is required, which consumes a lot of water resources. There are a lot of unfixed dyes and auxiliaries in the discharged wastewater, and there will be some heavy metals, which will cause serious pollution to the environment. With the increasing shortage of water resources, especially the continuous improvement of people's environmental awareness, the traditional dyeing technology is challenged, and people are pursuing a new technology of pollution-free dyeing that does not use water or uses less water. The supercritical CO2 dyeing ...
