Reactive Navy Blue FAQ
What fabrics work best with Reactive Navy Blue?
Reactive Navy Blue works exceptionally well on all natural cellulosic fibers including cotton, linen, hemp, and rayon. It also produces excellent results on silk and wool when properly mordanted. For synthetic blends, we recommend testing for colorfastness as results may vary depending on the synthetic fiber content.
How does Reactive Navy Blue compare to other navy blue dyes?
Reactive Navy Blue offers superior washfastness and lightfastness compared to direct or acid dyes. Its covalent bonding with the fiber ensures permanent coloration that resists fading. The dye maintains its rich navy tone even after 50+ washes, outperforming most alternatives in the market. Color consistency between batches is also significantly better with Reactive Navy Blue.
What safety precautions should be taken when using Reactive Navy Blue?
While Reactive Navy Blue is generally safe, we recommend wearing protective gloves and eyewear when handling the dye powder. Ensure proper ventilation in the working area and avoid inhalation of dust. The dye is biodegradable and meets most international environmental standards, but proper wastewater treatment is still recommended before disposal.
