Versatile Sulphur Blue BN – Ideal for Cotton and Cellulosic Fibers

1. Solve Your Key Dyeing Challenges – Where to Use

Sulphur Blue BN is specially designed for cellulosic fibers and their blends, including cotton, hemp, viscose, and vinylon. If you struggle with uneven dyeing, poor light fastness, or color inconsistency when producing navy blue or dark grey shades, this product provides a reliable solution. It also works effectively in direct printing on cotton and leather processing, making it a versatile choice for textile and leather manufacturers.

2. What Makes Our Sulphur Blue BN Attractive?

High Light Fastness (Grade 5-6) – Ensures long-lasting color even under sunlight exposure, significantly better than many conventional sulphur dyes. This is a key advantage for end-products like workwear, outdoor textiles, and automotive fabrics.

Distinctive Greenish-Blue Tone (青光) – Produces a clean, vibrant navy shade that is highly sought after in the denim and casual wear market. It can also be combined with yellow dyes to create deep dark grey shades with excellent depth.

Good Stain Resistance (Grade 3) – Reduces the risk of color bleeding onto adjacent fabrics during washing or wearing, improving overall product quality.

High Concentration Options (150% / 180% strength) – Allows you to achieve deeper shades with lower dye consumption, reducing your overall dyeing cost and inventory complexity.
