Sulphur Blue BRN or Sulphur Blue 7 for Denim Dyeing

Sulphur Blue BRN (also known as Sulphur Blue 7) is a cornerstone dyestuff in the denim industry, specifically formulated for achieving deep, classic blue shades on cotton and cellulosic fibers. This dye is highly valued for its excellent affinity to cotton, providing superior washing fastness and a characteristic tone that evolves beautifully through traditional denim laundry processes. It offers outstanding build-up properties and stability in continuous indigo-style range dyeing or exhaust dyeing, making it the preferred choice for manufacturers looking to produce high-quality, durable denim with a traditional aesthetic.
