🛠️ Troubleshooting – iDye Poly (EN)
iDye Poly are disperse dyes that work through high heat and physical penetration of the dye into synthetic fibers.
When results are not as expected, the cause is usually related to temperature, time, or material composition. The points below help explain what is happening and how to approach it.
🎨 The color looks pale or did not set properly
In most cases, this means the dye bath did not stay hot enough for long enough. iDye Poly requires continuous, strong boiling so the dye can properly penetrate the synthetic fiber.
👉 Check:
water temperature • boiling time • free movement of the material in the dye bath
🖤 Black looks greenish or olive
Black is one of the most demanding colors in disperse dyes. If the temperature is too low or the dyeing time too short, the result may shift toward green or olive tones.
👉 What helps:
steady, vigorous boiling • longer dyeing time
🧵 The result is two-toned
On blended fabrics (for example polyester/cotton), iDye Poly dyes only the synthetic portion. This is expected behavior and is related to how the dye interacts with different fiber types.
👉 Good to know:
• on 50/50 blends, the two-tone effect is clearly visible
• the higher the synthetic content, the more uniform the result
🪡 Seams or stitching remained lighter
In many ready-made garments, stitching threads are synthetic even when the fabric itself is natural. If the appropriate dye is not used for each material, seams may remain lighter.
👉 How this is approached:
by combining dyeing methods for natural and synthetic fibers, so each material receives the appropriate dye
👃 A strong odor remains after dyeing
With disperse dyes, an initial odor is normal, especially on synthetic materials.
👉 What helps:
repeated washing with hot water and a mild detergent until the odor is completely gone
🔘 Buttons or zippers also dyed
iDye Poly acts on many synthetic materials, not just fabric. Plastic buttons, zippers, and trims may also absorb dye.
👉 What to keep in mind:
• this effect can be integrated into the final aesthetic
• alternatively, components can be removed before dyeing, if possible
🌫️ You want a very light shade
Color intensity depends mainly on the amount of dye relative to the material.
👉 Approach:
use a smaller amount of dye or only part of the prepared solution for a softer result
🧺 Can a washing machine be used?
Dyeing synthetic fibers requires temperatures higher than those achieved by a household washing machine. For this reason, stovetop dyeing is the appropriate method.
👀 At a glance
With iDye Poly, the final result is primarily determined by:
temperature • time • material type
