Introduction To Airlaid Paper

Lid sinds 13 jul 2021

Airlaid Paper is a non-woven fabric, a textile-like material made of fluff pulp. It is made of 85% wood pulp and 15% binder. Airlaid paper is very loose, porous and soft. It has good water absorption properties. The raw pulp material is treated with special softness and water absorption. Therefore, compared with traditional paper towels, airlaid paper can hold up to six times its own weight of liquid, while having a higher wet strength. In the manufacturing process of airlaid paper, the fibers are brought into the airflow and from there into the moving belt or perforated drum, where a randomly inclined paper web is formed. Airlaid webs have lower density and higher softness than carded webs. Airlaid webs also have great adaptability in terms of fibers and fiber mixtures. The manufacture of airlaid paper is divided into three main steps: fiber opening, web formation and web formation. The physical properties of airlaid nonwovens make them suitable for a variety of disposable absorbent applications in consumer, industrial and institutional markets.

Airlaid paper has the following advantages: easy to handle after use-no laundry, textile-like surface and drape, very low lint, no dust, no static electricity, and it can be firm, clean and hygienic even when wet. It can also be disinfected.

According to the product, the airlaid paper market can be subdivided into multiple bonds, hot bonds, latex bonds and hydrogen bonds. Under latex bonding, according to the design of the production line, two different methods can be used to coat the latex adhesive on the paper web. Under thermal bonding, the fiber web must contain synthetic binder fibers (usually a two-component polyethylene and polypropylene). After compaction, the fiber web is transported to an oven to soften and melt the fiber skins and fuse them together, thereby bonding the various components of the fiber web together. The coil is then rolled to the correct thickness, cooled, and then transferred to the slitting/rewinding system. Hydrogen bonding uses the binding ability of cellulose fibers when the natural moisture contained in the fibers is removed and the fibers are in close contact. Generally, bonding is done under high temperature and high pressure conditions. This process eliminates the need to add synthetic binders to the airlaid web. Multiple bonding is a combination of latex and thermal bonding. The web is thermally bonded and a small amount of latex is sprayed on both sides of the web to reduce the lint that is often released during high-speed processing operations.

Air cushion paper can be divided into disposable wipes-household cleaning wipes, hand towels, desktop and food processing, personal care products-women's napkins and adult incontinence papers. Airlaid paper is mainly used for feminine hygiene products and wet wipes. Wet wipes can be used in many applications, such as shower gels, hand sanitizers, baby wipes, industrial wipes and household cleaning wipes.

By region, the global airlaid market can be divided into North America, Europe, Asia Pacific, Latin America, the Middle East and Africa. Europe is the dominant area of ​​the non-woven paper market, followed by North America. This can be attributed to the increase in the use of wet wipes in personal care and food processing in Europe.
