Direct Yellow 11 liquid

Overview

Direct Yellow 11 liquid is a water-dispersible direct dye formulated for industrial textile processes and specialty ink applications. Designed for straightforward handling and rapid color development, it delivers consistent warm yellow shades with strong wet-fastness and controllable leveling. Unlike commodity dyes, our formulation emphasizes dispersion stability and minimal foaming in high-shear processes.

Key advantages

• High dispersion stability — reduced sedimentation in storage and process tanks.
• Consistent shade batch-to-batch for repeatable production runs.
• Excellent wet-fastness and moderate lightfastness for many textile substrates.
• Easy integration into existing dyeing lines — low foam, quick solubilization.
• Optimized for woven and knitted cotton, viscose and certain paper/ink systems.

Processing tips (brief)

• Pre-dilute with warm water (30–40°C) and mix gently to obtain a uniform dispersion.
• Standard loading range: 0.2–2.0% o.w.f depending on target depth — run trials at lab scale.
• Use mild leveling agents for improved uniformity on knits; avoid strong oxidizers in formulation.

Why choose our Direct Yellow 11?

Many competitor dyes trade off dispersion stability for lower price. Our Direct Yellow 11 liquid is formulated to minimize downtime (less tank cleaning), reduce rejects from uneven dyeing and provide more predictable shade matching — saving time and cost across production batches.
