Acid Orange CAS 61968-66-9

Physical & Chemical Properties

We understand that you need precise data to determine if this dye fits your current recipe or process. Below are the typical characteristics of our Acid Orange.

Key Applications

Acid Orange (CAS 61968-66-9) is an anionic dye, meaning it bonds ionically with fibers in an acidic environment. Its molecular structure makes it particularly effective for protein fibers and synthetic polyamides.

1. Textile Dyeing (Nylon & Polyamide) This is the most common application. It is widely used in the production of swimwear, activewear, and hosiery where nylon is the dominant fiber. It provides excellent coverage and minimizes the “barré” effect (streaks) often seen in nylon.

2. Wool and Silk Processing For natural protein fibers, this dye offers a gentle affinity that preserves the soft hand-feel of the fabric while ensuring deep dye penetration. It is a staple for high-end wool yarns and silk garments.

3. Leather Dyeing It is also utilized in the leather industry for spray dyeing and drum dyeing, providing a rich, uniform base color for tanned leathers.

4. Blended Fabrics Ideally suited for Wool/Nylon blends (often found in carpet manufacturing), ensuring both fibers take up the color at similar rates for a uniform look.

Why Sourcing the Right Quality Matters

Not all dyes with the same Color Index (C.I.) number or CAS number perform the same. The difference lies in the manufacturing process—specifically in salt content and impurity removal.

• High Solubility: Our product is processed to minimize insoluble impurities, preventing filter clogging in your dye machines.
• Batch-to-Batch Consistency: We know that a slight shade variation can ruin a production run. We strictly control $\mathrm{\Delta }E$ΔE values to ensure the orange you buy today matches the orange you buy next year.

Safety and Precautionary Measures

While widely used, this is a chemical substance and should be handled with care in an industrial setting.

• Dust Control: Dye powders can be fine and dusty. Local exhaust ventilation is recommended to prevent inhalation.
• Personal Protective Equipment (PPE): Operators should wear appropriate respiratory protection (dust mask), safety goggles, and rubber gloves to avoid staining skin and eye irritation.
• Handling: Avoid eating, drinking, or smoking in the application area. Wash hands thoroughly after handling the dye.

Storage and Stability

To maximize the shelf life and ensure the powder remains free-flowing:

• Keep it Dry: Hygroscopic tendencies mean moisture is the enemy. Store in tightly closed containers.
• Temperature: Store in a cool, dry place away from extreme heat sources.
• Packaging: Reseal the liner immediately after taking out the required quantity to prevent moisture absorption from the air.
