| Summary: | The growing issue of beverage carton waste highlights the importance of recycling these materials. This study focused on utilizing recycled pulps from beverage cartons as hydrophilic core layers in disposable pet diapers, paired with nonwoven polylactic acid (PLA) as face layers. Recycled pulps were prepared in three fiber lengths: rough, intermediate, and ultrafine. These fibers were treated with a hydrophilic agent to enhance water absorption. Nonwoven PLA layers were fabricated using a melt-blown machine at varying air pressures of 0.2, 0.4, and 0.5 MPa and evaluated for air permeability. The water pick-up test results revealed that ultrafine recycled pulp fibers exhibited the highest water absorption at 17 times and were selected as the core material. Nonwoven PLA layers produced at 0.5 MPa demonstrated excellent air permeability of 911 L/m²/s, making them suitable as face layers. A prototype of the disposable pet diaper was successfully fabricated using a sewing machine, combining the optimized recycled pulp and PLA layers. This study provides an eco-friendly solution for recycling beverage carton waste into value-added products. |
