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.
There are so many uses of non-woven fabrics in our daily life such as in clothing, civil engineering, furnishing, manufacturing factory, kitchen, car, hospital etc.
Some special types of non-woven fabrics are as agro tech, build tech, medi tech, mobi tech, pack tech, cloth tech, geo tech, oeko tech, home tech, pro tech etc.

Types of Non-Woven Fabric Manufacturing Process: 
There are mainly four types of process followed to produce non-woven fabrics. Those are-

  1. Spun bond process,
  2. Melt blown process,
  3. Water jet process,
  4. Needle punched process.
