New Dyeing Process in 2022(Green Dyeing Technology)-2

Image
The new dyeing process includes new technologies such as waterless dyeing and low-temperature dyeing, in addition to the use of natural dyes and computer-controlled dyeing mentioned in  the previous article . Let us now look at the specific situation of these related processes. ​Waterless dyeing process Waterless dyeing is an important dyeing process to reduce dyeing wastewater, and it has many types. Solvent dyeing In the 1960s and 1970s in China, solvent dyeing was studied and popularized. While solvent dyeing has many benefits, some solvents, such as halogenated hydrocarbons, pollute the environment. Furthermore, the solvent recovery equipment must be increased, so it has yet to be popularized and applied. Supercritical carbon dioxide dyeing Supercritical carbon dioxide fluid has been used as a dyeing medium in recent years. Its most notable feature is that it does not dye with water. It can generally be washed without water or only lightly after dyeing. And carbon dioxide is vapori

With the progress of society and the improvement of people’s quality of life, people pay more and more attention to the environment and their own health. Wearing “green textiles” and “ecological textiles” has become the living needs of people in today’s world. Green dyeing technology is the key development direction of textile dyeing in the future. Green dyeing technology is distinguished by the use of non-harmful dyes and auxiliaries, as well as the dyeing and processing of textiles using non-polluting or low-polluting procedures. The amount of colored sewage emitted after dyeing is little, and it is easy to filter and deal with, as is the amount of energy consumed, and the dyed goods are “green” or ecological textiles. To that purpose, much research has been conducted in recent years both at home and abroad, and various innovative dyeing processes with lower pollution or ecological needs have been presented and pushed. Waterless dyeing, energy-saving dyeing, solubilizing dyeing, new

4 Dyeing Quality Issues with Rope Dyeing Machine

Rope dyeing machine , also known as rope dip dyeing machine. It is a type of equipment for interweaving thin silk, wool, cotton, and chemical fiber materials with loose, normal temperature rope dip dyeing. It is appropriate for many textile printing and dyeing operations, including loose rope scouring, dyeing, washing, and others. (An additional rope dyeing machine utilized in the denim facility will not be included in this article.) Types of rope dyeing machine Wool, silk, cotton, and their mixed knitted textiles, as well as chemical fiber imitation fabrics that are unsuitable for tension and pressing, are the major materials rope dyeing machines are used for. Additionally, it may be used to scrub, bleach, soap, and wash various silk, cotton, and cotton-blend knit materials. This is due to the elongation, chafing, and loosening that certain textiles are prone to. Dyeing and processing machinery should meet the special requirements of these fabrics with low tension and low friction. At
