The burnt-out printing technique, while offering unique aesthetic possibilities, can sometimes present challenges in production. Common defects such as incomplete penetration, fabric blackening, or unclear patterns can hinder efficiency and product quality. A thorough understanding of these issues and their remedies is essential for any textile print shop manager or quality control specialist. NINGBO INNO PHARMCHEM CO.,LTD. offers insights and solutions to help you effectively troubleshoot common textile burnt-out defects, ensuring consistent and superior results.


One of the most frequent problems encountered is incomplete paste penetration. If the burnt-out effect is clear on one side of the fabric but not the other, it often indicates insufficient penetration during the printing stage. This can be due to overly viscous paste, insufficient squeegee pressure, or even the presence of softeners on the fabric. Our recommended MF-9621 burnt-out paste usage guide emphasizes pre-treatment checks and proper dilution, along with adjusting printing pressure to ensure uniform paste application and thorough penetration through the fabric. For consistent results, always ensure your fabric is hydrophilic before printing.


Another critical issue is fabric blackening after baking, which signifies over-heat treatment. This can occur if the baking temperature is too high, the time too long, or the dosage of auxiliaries is imbalanced. To avoid this, it's generally better to bake at a lower temperature for a slightly longer duration. Our advanced burnt-out auxiliaries for textile industry, such as MF-15 (anti-scorch agent), are specifically designed to inhibit over-burning. However, careful adjustment of its dosage is crucial; too little can lead to blackening, while too much may inhibit the burnt-out effect entirely. NINGBO INNO PHARMCHEM CO.,LTD. can provide guidance on optimal temperature and time settings for our products.


When patterns are unclear or disappear after washing, it points to either an unsuitable fabric blend (e.g., 100% polyester, which is not suitable for burnt-out unless blended with cellulosic fibers) or incomplete heat treatment. Insufficient temperature or time prevents the acid from fully reacting with the cotton fibers. Conversely, excessive dosage of certain auxiliaries can also inhibit the reaction. Consulting the product's specifications and the polyester-safe textile burnt-out paste price can help confirm product suitability and cost-effective solutions to common problems.


Finally, isolated spots on patterns can result from air bubbles in the paste or insufficient pressing. Proper paste preparation, including defoaming time, and ensuring even pressure during printing, are simple yet effective solutions. By systematically addressing these common issues with the right chemical solutions and process adjustments, manufacturers can significantly enhance the quality and efficiency of their burnt-out printing operations.
