What is Airlaid Nonwovens

Compared to other nonwovens technologies, airlaid has the unique ability to lay down short fibers, either 100% pulp fibers, or mixtures of pulp and short cut synthetic fibers, to form a homogeneous and continuous web. It is also possible to mix in super absorbent powders or fibers thereby creating highly absorbent webs.

The airlaid web can be bonded in several ways. In latex bonding (LBAL), a liquid binder is applied to both sides of the web, which is thereafter dried and cured to achieve the dry and wet strength needed. Typical applications are table top products, dry and wet wipes, industrial wipes and household products. Thermal bonding airlaid (TBAL) includes bonding fibers, typically bicomponent fibers, in the web formation, and the web is heated to activate the melting components of the synthetic fibers to bond the web. Typically used for absorbent cores, where super absorbent powder can also be present and locked into the web structure by the synthetic fibers.

Multi bonding (MBAL) is a bonding process where latex and thermal bonding are combined, typically where the inner part of the product is thermal bonded and the surfaces have a slight layer of binder to eliminate dust and linting. Typically used for absorbent cores, household products, dry and wet wipes, these materials can also contain SAP.
