Feature	Description
Chemical Nature	Cationic (positively charged)
Solubility	Water-soluble
Color Fastness	Generally lower than other dye types; may require fixatives
Application Method	Commonly applied via padding, spraying, or immersion
pH Sensitivity	Sensitive to pH changes; optimal application at acidic pH
Light Fastness	Moderate; may fade under prolonged exposure to sunlight
Toxicity	Some basic dyes can be toxic; safety measures are essential during handling

Types of Basic Dyes

Basic dyes can be classified into several categories based on their chemical structure and application. The following table outlines the different types of basic dyes and their characteristics:

Type	Description
Cationic Dyes	Positively charged dyes that bond well with negatively charged fibers like acrylic and wool.
Direct Dyes	Used for direct application on fabrics; known for their bright colors.
Reactive Dyes	Form covalent bonds with the fiber, providing excellent wash and light fastness.
Disperse Dyes	Primarily used for dyeing synthetic fibers like polyester.
Acid Dyes	Suitable for protein fibers and nylon; offer bright shades and good fastness.
Metal Complex Dyes	Contain metal ions, enhancing color stability and fastness.
