Just look at the pockets for color stains!
Indigo denim has always been a timeless classic in the fashion market. However, in the denim washing process, creating jeans with a bright, layered color that doesn't stain is not easy.
Especially in the yeast wash process, the indigo dye is very easy to bleed and re-stain onto the fabric and pocket lining. If not handled properly, the white pocket lining can be stained indigo blue, resulting in color spots and a hazy appearance on the jeans, seriously affecting the quality of the garment.
Therefore, the most direct way to judge the quality of a pair of jeans—
is to take out the pockets and check for color stains!
Indigo is a reducing dye, and its properties are affected by temperature, pH, and enzymes (such as enzyme powder or enzyme water). The dye easily detaches from the fibers, forming free dye. If these free dyes are not promptly removed, they will re-adsorb onto the fabric surface, causing "re-dyeing."
Therefore, choosing a highly effective and stable anti-dyeing product is crucial in denim washing processes.
To solve the problems of back-dyeing and loss of elasticity during the denim washing process, the SYLIC brand has launched a new generation of denim-specific anti-dyeing solutions, covering various forms such as powder and paste, to suit different production needs.
| Product Name | Model | Characteristics | Application Instructions |
|---|---|---|---|
Anti-back Staining Powder | Sylic B6150 (CY-N10) | Light yellow powder, nonionic type | Suitable for denim anti-dyeing, anti-sticking, and elastic finishing. Enhances stone wash texture and fabric 3D effect. Can be used with EF21 at a 1:1 ratio. Recommended dosage: Prepare enzyme powder at 5–20% ratio, then dilute 10–30% before use (add 500–1000g diluted solution per machine). |
Anti-back Staining Powder | Sylic B6151 (CY-N20) | Polyester-based nonionic powder | Used for denim washing and anti-staining treatment. Works synergistically with enzymes to enhance and prolong anti-staining performance. Recommended dosage: Padding method: 0.5–2g/L; for combined use: enzyme 0.5g/L + dye repellent powder 0.5–2g/L. |
Anti-back Staining Powder | Sylic B6152 (CY-N50) | Polyether-based nonionic powder/flakes | Specially designed for denim washing anti-staining treatment. Excellent acid, alkali, and electrolyte resistance with minimal risk of elasticity loss. Recommended dosage: Same as B6150. |
Anti-back Staining Paste | Sylic B6153 (CY-N80) | Amber viscous liquid, solid content 59–61%, nonionic type | Liquid-type anti-dyeing product with excellent fluidity. Suitable for various denim washing processes. Extremely low elasticity loss, excellent synergy with enzymes for long-lasting anti-staining performance. Recommended dosage: 0.1–0.3%, pH 5.0–8.0, temperature 20–80°C. |

Dual Cleaning and Anti-Stain Function: Helps remove free dyes and sizing residues, simplifying the process.
No Loss of Stretch, Zero Risk: Non-ionic system, friendly to spandex and elastic fibers.
Instant Dissolving and Easy to Use, Small Packaging Saves Money: Simple operation and flexible material addition.
Promotes Enzyme Activity: Synergizes with enzyme reactions, increasing enzyme activity by approximately 15%, making the fermentation washing effect more obvious.
Green and Environmentally Friendly Formula: AEO/APEO-free, compliant with environmental regulations.
In actual production at a denim washing plant, after using the Sylic anti-dye series, the white pocket fabric remained pristine, and the jeans maintained a clear, three-dimensional appearance without any blurring.
Sylic's anti-dyeing series is not only an "invisible guardian" in the denim washing process, but also a professional choice for creating high-quality, zero-re-dyeing, and stretch-free denim.
Make denim more three-dimensional, cleaner, and better—starting with anti-dyeing.
