What are nonwovens?
Nonwovens are unique engineered fabrics offering costeffective solutions for an increasingly wide variety of applications. A more formal definition of "nonwoven" by ISO 9092 is:
A manufactured sheet, web or bat or directionally or randomly orientated fibres, bonded by friction, and/or cohesion and/or adhesion, excluding paper and products which are woven, knitted, tufted, stitch-bonded incorporating binding yarns or filaments, or felted by wet milling, whether or not additionally needled.
The fibres may be of natural or man-made origin and may be staple or continuous filaments.
How nonwovens are made?
The production of nonwovens can be described as taking place in three stages, although modern technology allows an overlapping of the stages. In some cases all three stages can take place at the same time.
The three stages are:
The opportunity to combine different raw materials and different techniques sites for the diversity of the industry and its products. This diversity is enhanced by the ability to engineer nonwovens to have specific properties and to perform specific tasks.
PGI is the exclusive manufacturer of Miratec® fabrics, produced using its proprietary APEX® fabric advanced laser technology, which serves markets as diverse as the textile industry itself. |
