Fabric burnt-out printing, while offering unique design possibilities, can sometimes present frustrating imperfections. Common issues include incomplete pattern clarity, unwanted blackening, or uneven penetration. Understanding the root causes of these problems and implementing targeted solutions is crucial for achieving consistent, high-quality results in your textile production.


One frequent complaint is when the pattern's face is clearer than the back, indicating incomplete paste penetration. This often occurs due to fabric softeners inhibiting absorption or insufficient pressure during printing. The solution lies in pre-treating the fabric for hydrophilicity, diluting the paste appropriately, increasing scraper pressure, or allowing more time for the paste to penetrate before heat treatment. These are vital aspects of understanding burnt-out printing problems and solutions.


Another pervasive issue is fabric blackening after baking, signaling over-heat treatment. This can be mitigated by adjusting the baking temperature (keeping it above 120ºC but preferring lower temps for longer durations), increasing machine speed to shorten heat exposure, or judiciously increasing the dosage of anti-scorch agents like MF-15. Knowing how to use MF-65 burnt-out paste components, including MF-15 anti-scorch agent benefits, can significantly reduce this risk.


Conversely, if the pattern is barely visible or disappears after washing, it suggests incomplete heat treatment or excessive auxiliaries inhibiting the reaction. Solutions involve raising the baking temperature, extending the time, or reducing the auxiliary dosage. Ensure the fabric is suitable for burnt-out printing, as some materials may not react as expected.


Finally, isolated spots within an otherwise clear pattern often point to trapped air bubbles in the paste or blockages. The fix involves ensuring proper paste preparation, allowing defoaming time, and potentially using additional pressure points near the oven to break any remaining bubbles. For reliable products to prevent these issues, consider a reputable textile paste supplier like NINGBO INNO PHARMCHEM CO.,LTD. Their specialized products can help you maintain high standards in your fabric printing process and avoid these common pitfalls.
