Classification of DyesI. Classification by Chemical StructureDyes are classified into: azo dyes, anthraquinone dyes, arylmethane dyes, indigo dyes, sulfur dyes, phthalocyanine dyes, nitro and nitroso dyes, as well as other structural types such as methine and polymetrazine dyes, stilbene dyes, and v Read More
Dyeing reactive turquoise blue is one of the difficulties faced by dyeing factories (especially reactive turquoise blue KN-G, G133, etc.). Problems such as color spots, stains, and poor fastness are easily encountered during dyeing. This article will focus on its structural principles to explain how Read More
How to Choose the Right Reactive Dyes?Ordinary reactive dyes initially produce vibrant colors, but the chemical bonds they form with fibers break after repeated contact with water and detergents, causing dye molecules to detach.How can this problem be solved?1. Choose dyes with high fixation rates. Read More
The most commonly used acid in printing and dyeing factories: acetic acidAcetic acid (chemical formula CH3COOH), commonly known as acetic acid, is an organic monobasic acid. Acetic acid with a content of 98% freezes at low temperatures and is commonly known as glacial acetic acid. The pH value of an Read More
pHFor active dyeing, when the pH value is 7 ~ 9, the color difference between the product is normal, indicating that the pH range has little effect on the product color difference, and the presence of a small amount of alkali will not change or destroy the active dye molecules.When the pH value is 8 Read More
There are many reasons for the color difference between samples, and the main reasons are the following aspects.① Be strict and accurate when playing samples. Sample samples are the key to directly affecting the large -scale production of the workshop. We must fully understand its importance and pay Read More
