What is wet laid?
ABSTRACT. Wet laying is an emerging technique for the production of nonwoven using short natural cellulosic fibers and their blends unlike other nonwoven techniques that utilize chemicals and require a particular length of fibers for processing into nonwoven.
What is airlaid material?
Air-laid paper is a textile-like material categorized as a nonwoven fabric made from fluff pulp. Compared with normal wet-laid paper and tissue, air-laid paper is very bulky, porous and soft. It has good water absorption properties and is much stronger compared with normal tissue.
Is polyester a non-woven fabric?
Nonwoven polyester fabric can be created from 100% polyester filament or polyester blend. Nonwoven polyester is an excellent choice for a wide range of application needs including industrial filter materials, medical and hygiene products, construction materials, telecom products, agricultural fabric, and more.
What is Wetlaid material?
In the wetlaid process, staple fibers of up to 12 mm fiber length, very often mixed with viscose or wood pulp, are suspended in water, using large tanks. Afterwards the water-fiber- or the water-pulp-dispersion is pumped and continuously deposited on a forming wire. The water is sucked off, filtered and recycled.
What is wet laid non woven?
Wet-laid nonwovens are nonwovens made by a modified papermaking process. That is, the Fibers to be used are suspended in water. Specialized paper machines are used to separate the water from the Fibers to form a uniform sheet of material, which is then bonded and dried.
