Trade Name: REACTOBOND ORANGE 3R · CI Number: Reactive Orange 16
Reactive Orange 16 is a bright, vivid orange reactive dye for cotton and cellulosic fibre dyeing. It delivers high tinctorial strength and good wash fastness through covalent bonding with cellulose. Supplied by Yobai Industries as REACTOBOND ORANGE 3R with consistent batch testing.
REACTOBOND ORANGE 3R produces a clean, vivid orange with no brown or red drift, making it the standard choice for brightness-critical applications — sportswear fabrics, high-visibility yardage, and the orange component in trichromatic reactive shade recipes. In trichromatic combinations, it pairs with a yellow (such as Reactive Yellow 17) and a red (such as Reactive Red 198) to cover the full orange-through-rust gamut on cotton. Hot soaping at 95°C after fixation is mandatory — unfixed hydrolysed dye not removed by thorough soaping will result in poor wet rubbing fastness even when initial shade depth appears correct.

Fastness ratings are on the standard 1–5 scale (5 = best). Light fastness 4–5 is typical for orange azo reactive dyes — adequate for most fashion and apparel applications, though prolonged outdoor exposure should be assessed by the end user.

REACTOBOND ORANGE 3R dissolves well in warm water — approximately 50–80 g/L at 40–50°C. Dissolving at 40–50°C is recommended over room temperature dissolution, particularly at higher concentrations used for deep orange shades. Pre-pasting the powder in a small quantity of cold water before adding warm water prevents clumping and ensures a uniform, fully dissolved stock solution before addition to the bath.
Filter the dissolved dye through a 100-mesh screen before adding to the dyebath. Do not dissolve in alkaline water — add the dye stock to the neutral bath first, and introduce alkali only after the substrate has had adequate time to absorb the dye with salt assistance. This sequence ensures that the reactive vinyl sulphone group does not hydrolyse prematurely before fixation.
All values are for cotton exhaust dyeing at liquor ratio 1:10. Add NaCl in 2–3 stages before alkali addition to ensure even exhaustion across the shade range.

The swatches below represent typical application outcomes on 100% combed cotton under standard exhaust bath conditions. Actual shade depends on fibre quality, water hardness, and process variables. Request a sample dyed swatch before committing to bulk production.
Request a shade card or sample dyed swatch from technical@yobaiindustries.in to verify shade match before production.
Store in a cool, dry location below 25°C. Reactive dyes are sensitive to moisture and elevated temperatures — keep containers sealed at all times. Avoid storage near acidic materials. Protect from direct sunlight.
