Non-Woven Fabric Manufacturing Process | Raw Materials for Non-Woven Fabric

What is Non-Woven Fabric? 
Non-woven fabric is a web or sheet which is produced by using natural or man-made fibers or filaments or recycled fibers that have not been converted into yarns. Finally these are bonded by following different methods to form non-woven fabric. It may also have other names such as shaped fabrics or yarn free fabrics.
