About the production method of Airlaid Paper
The chemical bonding method uses 100% wood pulp fibers as raw materials, opens the fibers in a single fiber state, flows into the network through air, and sprays the water-soluble adhesive on the surface of the network by spraying, baking and strengthening it to form a cloth.
The thermal bonding method is to mix hot melt fibers with wood pulp fibers, and the mixing ratio is generally not less than 15%. After the airflow enters the net, the low-melting fiber in the net is melted by hot air or hot rolling, and the net is consolidated into a cloth. Since the thermally bonded non-woven fabric does not contain chemical adhesives, the product is more bulky and moisture-absorbing, and is mainly used as the absorbent core of high-absorbent sanitary products and thin feminine sanitary napkins. For this purpose, some production lines are equipped with high-absorbent resin (SAP) powder application devices. Due to the addition of polymer water-absorbing resin, it can become solid after absorbing water, which greatly improves its water absorption capacity.
In summary, although dust-free paper is called paper, it is essentially a non-woven fabric.
