What are Nonwoven Fabrics?

What is air laid?
"Air laid" nonwoven fabrics are manufactured without using water. Separately loosened fibers and fine particles are uniformly dispersed in an airstream and laid on a metal mesh for bonding.
The raw materials and manufacturing methods used for nonwoven fabrics are many and various. Manufacturing methods consist of the wet-type and the dry-type, the latter being further divided into the adhesive type, the machine bonded type, the yarn spun type and a variety of others. Of these, air laid belongs to the adhesive type.
What is pulp air laid
"Pulp air laid" refers to air laid nonwoven fabrics made principally of pulp. Normally, the term "air laid" refers to pulp air laid.
What is synthetic fiber air laid?
"Synthetic fiber air laid" refers to air laid nonwoven fabrics made from chopped 100% synthetic fibers with a fiber length of about 1-12mm. The term "synthetic fiber air laid" is used to distinguish these from pulp air laid.
Oji Kinocloth's nonwoven fabrics
In 1964, Oji Kinocloth became the first company in the world to succeed in manufacturing pulp air laid nonwoven fabrics using wood pulp as the primary material. There are now three air laid methods, but our air laid method uses technology unique to the company, and is known throughout the world as the Oji method.
The fruit of this manufacturing method was Kinocloth. Since air is used to disperse the pulp fibers, the web density is very low, yielding four characteristics: (1) liquid retentiveness, (2) filtration, (3) bulkiness, and (4) softness. These characteristics are exploited in a wide variety of products, and are the subject of considerable interest as materials that will expand possibilities for the future.
History of nonwoven fabrics
The Kojien dictionary describes nonwoven fabrics as "Fabrics manufactured by mechanically, chemically or thermally processing fiber sheets (webs) without forming thread, and binding them together using adhesive or the interlocking action of the fibers themselves".
Nonwoven fabrics are widely used in fields such as industry, apparel, medicine, and livingware. In Japan, the annual production output was in excess of about 340,000 tons in 2007. In 1964, Oji Kinocloth became the first company in the world to succeed in manufacturing pulp air laid nonwoven fabrics using wood pulp as their primary material. These are now in wide use as products, thanks to their combined advantages of the soft touch of cloth and the low cost of paper.
