FAQS on types of reactive dyes

Q: What are the main types of reactive dyes used in textile industries?

A: The primary types include cold reactive dyes (low-temperature application), hot reactive dyes (high-temperature fixation), and vinyl sulfone-based dyes. These categories differ in reactivity, application methods, and fabric compatibility.

Q: How do reactive dyes types differ in terms of chemical structure?

A: Reactive dyes are classified by their reactive groups, such as monochlorotriazine (MCT), dichlorotriazine (DCT), and vinyl sulfone (VS). Each group determines fixation efficiency, colorfastness, and compatibility with specific fibers like cotton or silk.

Q: Where can I find a detailed "types of reactive dyes PDF" for research purposes?

A: Detailed PDFs on reactive dye types are available through academic databases like ScienceDirect, textile industry publications, or manufacturer websites (e.g., Huntsman, Archroma). Many universities also provide free access to technical guides.

Q: What distinguishes cold reactive dyes from other reactive dyes types?

A: Cold reactive dyes bond with fibers at lower temperatures (20–40°C) using alkali activation, ideal for delicate fabrics. In contrast, hot reactive dyes require higher temperatures (80–90°C) for fixation, offering better wash-fastness on heavy textiles.

Q: Which reactive dyes types are best suited for cotton fabric dyeing?

A: Vinyl sulfone-based reactive dyes (e.g., Remazol) and bifunctional dyes (e.g., Procion HE) are optimal for cotton due to high fixation rates and colorfastness. They form covalent bonds with cellulose fibers during alkaline dyeing processes.
