(indigo blue)
A: Indigo Blue is a natural dye primarily used for coloring denim fabric. It creates the classic blue hue in jeans and is valued for its colorfastness. Modern suppliers often blend it with synthetic dyes for cost efficiency.
A: Bromo Indigo is a chemically modified version of natural indigo with enhanced solubility. It offers brighter color intensity for specialty fabrics but requires stricter handling protocols. Both dyes are used in denim production but serve different aesthetic needs.
A: Reputable suppliers should hold Oeko-Tex or GOTS certifications for eco-friendly practices. They must provide SDS sheets for chemical compositions. Look for ISO 9001 compliance to ensure quality control standards.
A: Many factories now offer batch customization for niche markets. Minimum order quantities vary but typically start at 50-100kg. Some Indian and Japanese specialists provide organic options for artisan producers.
A: Bromo Indigo bonds better with synthetic fibers like polyester blends. It maintains vibrancy through repeated washes and sweat exposure. The synthetic variant also enables precise color matching for brand consistency.
