Pre-treatment and dyeing of home textile green dyeing and finishing technologyAt present, the production of home textile fabrics that meet the requirements of ecological and environmental protection has become an important direction of product development for the majority of home textile product man
Analysis on the types of environmentally friendly dyesCommonly used sulfur dyes are not allergic dyes, carcinogenic dyes, and acutely toxic dyes. They do not contain heavy metals and adsorbable organic halides. They use less salt during application and consume much less water and energy than reactiv
What should I do if color spots and stains appear in reactive dyeing?Reactive dyes have a very good solubility in water. Reactive dyes mainly rely on the sulfonic acid groups on the dye molecules to dissolve in water. For meso-temperature reactive dyes containing vinylsulfone groups, in addition to
Basic principles of disperse dyeing1. Dyeing performance of polyester fiberPolyester is a hydrophobic fiber. The fiber lacks groups that can bind to dyes. It cannot be dyed with water-soluble dyes. It can only be dyed with non-ionic disperse dyes with low molecular weight, no strong ionic water-solu
Basic knowledge of disperse dyes (2)1. What is hot melt pad dyeing?The hot melt pad dyeing process is suitable for continuous dyeing of polyester/cotton blended fabrics. Its dyeing principle is also a kind of high temperature dyeing. The difference from high temperature and high pressure is that the
Basic knowledge of disperse dyes (1)Disperse dyes were produced by the Baden Aniline Soda Company in Germany in 1922 and are mainly used for dyeing polyester fibers and acetate fibers. At that time, it was mainly used for dyeing acetate fibers. After the 1950s, with the emergence of polyester fiber,
The dyeing performance of disperse dyes-lifting power1. Definition of lifting power:Lifting power is one of the important properties of disperse dyes. This characteristic indicates that when each dye is used in dyeing or printing, the amount of dye is gradually increased, and the degree of color dep
Basic dyeing with disperse dyesDyeing polyester with disperse dyes is generally carried out under acidic conditions.So, what are the advantages and disadvantages of dyeing with disperse dyes under alkaline conditions? Please look down.1. The emergence of alkaline dyeing with disperse dyes:When dyein
The role and influence of film-forming additives in coatingsWith the rapid economic development nowadays, the chemical industry has gradually occupied an important position.
