Analysis of moisture management behaviour of sanitary napkins

This study aims to develop an exceptionally absorbent and comfortable feminine hygiene product. This involves crafting a surface layer exclusively composed of bamboo spun-laced material. The core layer incorporates varied blends of bamboo, flax, and hemp fibres combined in specific ratios to maximise comfort and absorbency. Enhanced absorbency is achieved by incorporating a super absorbent polymer (SAP) in the middle layer, swiftly locking in menstrual fluids. Fabrication involves mechanical extraction and processing of bamboo fibres for the top layer, while the core layers are formed using wet-laying techniques. Comprehensive testing evaluates moisture management performance, with wetting time measurements revealing superior absorption rates and spreading speeds in Sample S3, attributed to its optimal material composition. Additionally, Quantitative indices such as the Accumulative One-Way Transport Index (AOTI) and Overall Moisture Management Capacity (OMMC) further confirm Sample S3 as the top performer in efficiently absorbing and distributing moisture,ultimately ensuring user comfort and satisfaction. This detailed approach underscores the importance of material selection and structural design in producing high-quality sanitary napkins, emphasising the potential for sustainable and effective menstrual hygiene products.
