Nonwovens:
Non –woven fabric are the fibrous sheet or web structure produced by bonding or interlocking fibers by mechanical , thermal or chemical means.
Natural and Synthetic fibers which are used for manufacturing nonwovens are elaborated along with their properties and applications in the following article.

-Natural Fibers

1-Cotton

Properties:
  •         Length- 5mm to 38 mm
