Multi-Layer Airlaid Web Formation Systems
topic
Multi-forming head airlaid lines use sequential forming stations depositing different fibre types, SAP concentrations, and functional additives in separate layers to produce gradient structure webs with different properties at each surface and through the thickness, enabling construction of absorbent cores with defined acquisition layer, storage layer, and distribution layer functions in a single continuous production process.
Role
Enables engineered multi-layer absorbent structures with defined functional zone properties in a continuous production process by sequentially depositing different material compositions from multiple forming heads, with multi-layer airlaid being the enabling technology for the thin structured absorbent cores of modern premium hygiene products that provide rapid acquisition at the surface and high retention capacity in the core without the bulk of traditional fluff pulp absorbent pads.
