Textile printing is an intricate process, and while it offers immense creative possibilities, it’s not immune to defects. Common issues like incomplete penetration, fabric blackening, and unclear patterns can significantly impact product quality and lead to costly reworks. Understanding how to diagnose and resolve these textile printing defects is crucial for any successful operation. This guide focuses on solutions, particularly for burnt-out printing, where chemical interactions play a key role in the final aesthetic.


One frequent problem in burnt-out printing is incomplete penetration, where the chemical paste doesn't fully seep through the fabric, leading to patterns that are clearer on one side than the other. This can often be traced back to fabric pre-treatment (presence of softeners inhibiting absorption) or insufficient pressure during printing. Solutions include thorough hydrophilic treatment of the fabric, diluting the printing paste slightly, increasing scraper pressure, or incorporating an empty version near the oven to ensure even pressure and paste distribution, ultimately seeking solutions for incomplete burnt-out patterns.


Perhaps the most frustrating defect is fabric blackening after baking, especially when the goal is a transparent effect. This usually indicates over-heat treatment. The fabric turns yellow, then brown, and finally black if over-baked. To prevent fabric blackening in burnt-out printing, several adjustments can be made: lowering the baking temperature (though not below 120°C), shortening the fabric's time in the drying room, or appropriately increasing the dosage of the burnt-out auxiliaries. NINGBO INNO PHARMCHEM CO.,LTD. provides MF-15, an effective anti-scorch agent textile printing MF-15, which plays a critical role in inhibiting over-burning without compromising the burnt-out effect, ensuring clean and crisp results.


Another challenge is the pattern not appearing at all after baking and washing. This could be due to unsuitable fabric composition (e.g., 100% polyester for a cellulosic-removal process), incomplete heat treatment (temperature too low, acid not activated), or excessive dosage of auxiliaries which can have an inhibitory effect. Adjusting temperature and time, or reducing auxiliary dosage if it's too high, are key countermeasures. The delicate balance of paste consistency, baking conditions, and auxiliary amounts is paramount for optimal burnt-out printing outcomes.


NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting textile businesses with comprehensive textile printing solutions, addressing these common defects to achieve consistent, high-quality results. Our specialized chemicals, like the MF-9621 Three Component Burnt-out Paste system, are formulated to provide greater control and predictability in the printing process. By understanding and implementing these solutions, manufacturers can minimize waste, enhance efficiency, and consistently deliver perfectly printed fabrics to their customers.
