Nonwoven surface treatments for disposable hygiene products

Official URL: https://dx.doi.org/10.1002/pen.27099

Baby diapers, adult incontinence products, feminine hygiene items, and wet wipes are extensively utilized nonwoven products. The properties of nonwovens are significantly influenced by surface treatments. These treatments impart hydrophilicity, hydrophobicity, skincare benefits, adhesion reduction, odor control, enzymatic inhibition, pH control, probiotics, prebiotics, controlled release of active agents, and antimicrobial activity, all of which enhance the performance and user experience of these products. This study reviews surface treatments for nonwoven disposable hygiene products, focusing on their types, effects, performance, and safety considerations. Most research focuses on hydrophilicity and hydrophobicity due to the absorbent nature of these articles. Small molecule applications are prominent, though polymer-based formulations offer greater versatility. Smart materials, nanofibers, and nanoparticles are becoming increasingly popular in the field. Concerns regarding sustainability, biodegradability, biocompatibility, product safety, and compliance with emerging environmental regulations are increasing. Focusing on these areas will drive the development of next-generation disposable hygiene products that meet changing regulations, consumer demands and concerns. Highlights: Innovative agents improve user comfort and hygiene in surface treatments. Small molecule treatments are common although polymers provide more versatility. Smart coatings and nanomaterials offer advanced surface treatments. Biodegradable treatments lead the shift towards sustainable hygiene products. Consumer preferences shape the next generation of hygiene articles.
