Cationic Orange FAQ Section
Q: What types of fibers can Cationic Orange dye effectively?
A: Cationic Orange is primarily designed for polyacrylonitrile fibers (acrylic) but also works well on modified nylons, some polyester blends, and cationically modified cotton. The dye molecules have strong affinity for fibers with negative charge sites.
Q: How does Cationic Orange compare to other orange dyes in terms of light fastness?
A: Cationic Orange offers superior light fastness (6-7 on the ISO Blue Scale) compared to most acid or direct dyes (typically 4-5). This makes it particularly suitable for outdoor textiles and applications requiring long-term color stability.
Q: What safety precautions should be taken when handling Cationic Orange?
A: While Cationic Orange is classified as non-hazardous under normal conditions, we recommend using basic PPE including gloves, goggles, and dust masks when handling the powder. Ensure good ventilation in the working area and avoid creating dust clouds. Store away from food products and always wash hands after handling.
