Description

C.I.Disperse Blue 108 is a high-performance, anthraquinone-based disperse dye widely used in synthetic fiber coloration. This product is valued for its excellent color fastness properties, including good lightfastness and wash fastness, which are critical for durable textile applications. It is primarily needed by manufacturers in the polyester, acetate, and nylon dyeing and printing industries to achieve vibrant and stable blue shades.

Application

• Dyeing of polyester fibers and fabrics, including textured yarns (PTY).
• Coloration of acetate and triacetate materials.
• Printing applications on nylon and synthetic blend textiles.
• Used in the high-temperature dyeing process for synthetic garments and home furnishings.
• Employed in the mass coloration of synthetic polymers during the melt-spinning stage.
• Suitable for automotive textiles requiring consistent color and durability.
• Application in the dyeing of polyamide fibers for sportswear and activewear.
