Innovative Modifications in Cellulose Hygiene Paper: Enhancing Strength and Disintegration Through Sustainable Processing
摘要
Sanitary sewer overflows present significant epidemiological hazards, often resulting from system capacity limitations and blockages caused by flushable products like toilet paper. Modern toilet paper production methods emphasize efficiency, quality, and scalability, leveraging technologies such as high-speed lamination, precision adhesive application, and optimized fiber blending. While these processes enhance usability and durability, they often overlook environmental challenges, contributing to wastewater management issues. This study proposes a practical approach to improving the disintegration properties of toilet paper without compromising its mechanical performance or requiring significant changes to manufacturing practices. The solution improves disintegration rates by incorporating biodegradable polymer-based modifiers into the adhesive used during lamination while preserving essential properties such as strength and tear resistance. Tests using starch and glycerol additives demonstrated a 10% reduction in sinking and disintegration times. Further trials with 3% and 6% plasticized potato starch solutions achieved a 24% and 33% decrease in the disintegration index, respectively, with minimal impact on product quality. The proposed solution requires only minor adjustments to adhesive formulations, enabling straightforward integration into existing production lines. This method demonstrates how advanced manufacturing techniques can address environmental challenges effectively while maintaining production efficiency and high-quality standards.
