Airlaid Nonwoven Technology
The term airlaid nonwoven refers to a manufacturing technology that produces a web from short fibres, most often softwood pulp. The process is also referred to a short fiber airlaid technology to distinguish it from the Rando Weber airlaid process that handles long synthetic fibers, generally rayon or polyester.
While the principal fiber used to produce airlaid nonwovens is fluff pulp other natural and synthetic fibers can be used. The airlaid process was originally conceived as a method of making paper without the use of water. In paper making, wood pulp is bonded principally by a chemical reaction between the pulps natural cellulose and water. To enhance the papers strength, bonding agents such as resin are added. In contrast, airlaid nonwoven technology generally uses latex emulsions, thermoplastic fibers or some combination of both to bond the web’s fibers and increase the strength and integrity of the sheet. The process yields a paper-like fabric that is thicker, softer and more absorbent than paper. It also has greater tear resistance and tensile strength, particularly when wet.
These physical characteristics of airlaid non-wovens make them suitable for many disposable absorbent applications in consumer, industrial and institutional markets. The main product categories where airlaid nonwovens are currently used include:
