Trade Name: REACTOBOND GOLDEN YELLOW G · CI Number: Reactive Yellow 17
Reactive Yellow 17 is a golden yellow reactive dye widely used in cotton textile dyeing and trichromatic shade recipes. Its warm hue and good wash fastness make it suitable for fashion apparel, home textiles, and industrial fabric production. Supplied by Yobai Industries as REACTOBOND GOLDEN YELLOW G.
The warm, amber-leaning golden-yellow hue of REACTOBOND GOLDEN YELLOW G makes it the standard yellow in trichromatic reactive systems for autumn, mustard, khaki, and earth shade ranges on cotton. In combination with Reactive Red 198 and Reactive Blue 89 or Reactive Blue 21, it covers the full yellow-to-dark-brown gamut. Standard VS-class exhaust conditions (NaCl 40–60 g/L, Na₂CO₃ 15–20 g/L, 60°C) match those of compatible reactive reds and blues, making trichromatic combination dyeing straightforward. Hot soaping at 95°C after fixation is mandatory — unfixed yellow hydrolysate is well-known to produce poor wet rubbing fastness if the soaping step is abbreviated.

Hot soaping at 95°C after fixation is especially important for yellow reactive dyes — unfixed yellow hydrolysate is known to cause poor wet rubbing fastness if not thoroughly removed. Contact technical@yobaiindustries.in for application-specific guidance.

Fastness ratings are on the 1–5 scale (5 = best). Light fastness 4–5 is standard for yellow azo reactive dyes — suitable for fashion and interior textiles; assess for prolonged outdoor exposure per end-use requirement. Batch COA available from technical@yobaiindustries.in.
REACTOBOND GOLDEN YELLOW G dissolves well in warm water — approximately 50–80 g/L at 40–50°C. Monoazo VS-class yellows are among the easier reactive dyes to dissolve, but thorough dissolution before bath addition is still important. Undissolved particles in the bath settle unevenly and produce spots; in pale yellow shades, these spots are visible and difficult to correct after fixation.
Pre-paste the powder in cold water, then add warm water (40–50°C) with continuous stirring until fully dissolved. Filter through a 100-mesh screen before adding to the bath. Dissolve at neutral pH and add the stock to the bath before introducing salt — never dissolve in alkaline solution, as the vinyl sulphone reactive group begins to react in alkaline conditions and will reduce fixation yield if the solution ages before use.
All values are for cotton exhaust dyeing at liquor ratio 1:10. Add NaCl in 2–3 stages before alkali addition. Hot soaping at 95°C is mandatory — never abbreviate this step for yellow reactive dyes.

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.
