AI Technical Summary
Technical Problem
Existing nonwoven fabrics used in hygiene materials like disposable diapers and sanitary napkins face issues with stretchability and stress retention, leading to misalignment and reduced effectiveness at body temperature.
Method used
A multilayer nonwoven fabric comprising an elastic nonwoven fabric made of an α-olefin copolymer with a specific storage elastic modulus ratio and an extensible spunbonded nonwoven fabric, which enhances stretch characteristics and stress retention.
Benefits of technology
The multilayer nonwoven fabric maintains excellent stretchability and stress retention across temperature changes, preventing misalignment and improving moldability and productivity.
