In the dyeing of polyester ($PES$) fibers, the primary objectives are to increase dye yield and ensure color uniformity (leveling). CRN SOFT WG 113 is a multi-functional carrier developed to enhance the mobility of disperse dyestuffs within the fiber while acting as a powerful leveling agent.
Dual-Action Performance: Carrying and Leveling
CRN SOFT WG 113 combines the dye exhaustion power of traditional carriers with an advanced leveling mechanism.
Effective Carrying Potency: Loosens the polyester fibers at a molecular level, allowing the dyestuff to penetrate the fiber structure rapidly and deeply. This ensures high color yield and saturated tones even at lower temperatures.
Leveling Property: Regulates the rapid, localized fixation (strike) of the dyestuff onto the fiber. It ensures the dye is distributed homogeneously across the entire fabric, preventing quality defects such as "barré" (color unevenness) and side-to-center variations.
Process Safety and Fiber Compatibility
The product provides a safe working environment for dyeing sensitive synthetic blends and challenging fabric constructions.
Migration Capability: Promotes the relocation (migration) of dyestuff molecules during the dyeing process. This feature helps dissipate any potential dye concentrations on the fabric, resulting in a smooth appearance.
Low-Temperature Advantage: Optimizes the dyeing temperature in cases where HT (high temperature) conditions cannot be reached or for heat-sensitive blended fibers (PES/Wool, PES/Viscose, etc.), preventing fiber damage.
Key Advantages of CRN SOFT WG 113
Minimal Spotting Risk: Due to its specialized formulation, it maintains stability at high temperatures and does not cause issues like oil spots or dye precipitation on the fabric.
Corrective Role: Its high leveling power makes it an effective auxiliary for re-leveling processes intended to fix faulty dyeings.
Fastness Support: Assists the dyestuff in becoming trapped within the fiber core, ensuring washing and rubbing fastness values meet targeted standards.
No Impact on Light Fastness: It can be easily removed from the fabric post-dyeing, meaning it does not adversely affect the light fastness of polyester materials.
