Burnt-out printing is an intricate process that, while capable of producing stunning textile effects, can sometimes present challenges. Manufacturers and designers often encounter issues such as incomplete penetration, fabric blackening, or indistinct patterns. Understanding the root causes and applying effective solutions is key to achieving consistent, high-quality results. NINGBO INNO PHARMCHEM CO.,LTD. provides insights to troubleshoot common burnt-out printing process problems and optimize your operations.


One frequent issue is incomplete penetration, where the face of the fabric is clearer than the back after washing. This often stems from insufficient paste penetration. The solution involves ensuring the fabric is hydrophilic before printing, diluting the paste appropriately, and increasing scraper pressure or passes. Allowing enough time for the paste to penetrate before baking is also crucial. For those seeking a reliable burnt-out printing textile chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers the MF-9621 paste, which boasts good penetration uniformity, helping to mitigate this common issue.


Another significant challenge is fabric blackening or difficulty in cleaning after baking. This typically indicates over-heat treatment. Remedies include lowering the baking temperature (though not below 120°C), shortening the fabric's time in the drying room, or appropriately increasing the dosage of MF-15, our anti-scorch agent for textile printing. MF-15 is designed to inhibit over-burning, ensuring the fabric achieves the desired crisp, yellow, and crispy state without turning black. A lower temperature and longer baking time are generally safer and easier to control for optimal results.


If patterns are not visible after baking and washing, the issue could be that the fabric is unsuitable (e.g., 100% polyester), heat treatment was incomplete (insufficient temperature or time), or an excessive dosage of auxiliaries inhibited the burnt-out effect. Adjusting temperature, extending baking time, or reducing auxiliary dosage as needed can rectify this. NINGBO INNO PHARMCHEM CO.,LTD. recommends thorough testing based on fabric type and process conditions.


Finally, random spots on patterns can result from blockages or bubbles in the paste. Ensuring the paste is well-blended, defoamed, and filtered before use can prevent these imperfections. By systematically addressing these common challenges, textile businesses can achieve consistent, beautiful burnt-out effects, enhancing fabric quality and design versatility with confidence.
