The Basics of Acid Dyes: Types, Properties and Applications
2023年11月16日 · Acid dyes have a chemistry that makes them indispensable for colouring textiles. These dyes are a class of water-soluble anionic dyes known for their affinity to protein-based fibres such as wool, silk, and nylon.
Characteristics, Types and Application of Acid Dyes - Textile Learner
2012年1月10日 · Types and Classification of Acid Dyes: In use, acid dyes are classified by their dyeing behavior and wet fastness properties, rather than chemical composition. Dyeing behavior is, however, determined to a great extent by relative molecular mass …
Acid dye - Wikipedia
Acid dyes are generally divided into three classes according to their fastness requirements, migration ability, and dyeing pH. [5] Acid dyes affix to fibers by hydrogen bonding, Van der Waals forces [6] and ionic bonding. While some acid dyes work in water, many choose to activate dyes in acid dye-baths instead.

Fastness Properties of Acid Dyes - Textile Learner
2012年1月20日 · Acid dyes are highly water soluble, and have better light fastness than basic dyes. The textile acid dyes are effective for protein fibers such as silk, wool, nylon and modified acrylics. They contain sulphonic acid groups, which are …
A Scientific Overview of Acid Dyes - DYES / Alfa Chemistry
Acid dyes represent a significant class of water-soluble dyes known for their affinity to protein fibers and certain synthetic fibers. These dyes contain acidic functional groups, primarily sulfonic acid (-SO 3 H) or carboxylic acid (-COOH), which play a key role in their ability to interact with fibers under acidic conditions.

2020年5月1日 · In this review, the dyes will be studied in three different groups depending on the chemical structures with an overview on the synthesis of some new dyes, color index numbers (C.I.) and application methods. Finally, it would be also interesting to briefly discuss the effects of the textiles dyes on environment. 1. Introduction.
Comprehensive Guide to Acid Dyes: Applications and Benefits
2024年8月10日 · Acid dyes are water-soluble anionic dyes that require an acidic environment to bond with fibers. These dyes are primarily used for dyeing protein fibers like wool, silk, and nylon. Acid dyes are known for producing bright, vivid colors with good lightfastness and washfastness.
