The Chemistry Of Synthetic Dyes. Reactive Dyes May 2026
Generally requires salt to drive the dye into the fibre and alkali to fix it. 🌍 Environmental Impact
The dye attaches to the fibre through a chemical reaction triggered by alkaline conditions (high pH). There are two main types of reaction mechanisms: 1. Nucleophilic Substitution The Chemistry of Synthetic Dyes. Reactive Dyes
The chemistry of reactive dyes centers on their unique ability to form a permanent covalent bond with the substrate, typically cellulose (cotton) or protein fibres (wool/silk). Unlike other dyes that simply "sit" on or inside the fibre, reactive dyes become a chemical part of the fibre itself. 🧪 Chemical Structure Reactive dyes consist of four primary components: Generally requires salt to drive the dye into
