In Simple tongue, the Fabric without weaving is called Non-woven Fabric. It can be divided into various kinds by different technologies.
Usually, Nonwoven Fabric are manufactured by putting small fibers together in the form of a sheet or web, just like paper on a paper machine and then binding them either Mechanically as in the case of felt, by interlocking them with serrated needles such that the inter-fiber friction results in a stronger fabric, with an adhesive, or Thermally by applying binder in the form of powder, paste, or polymer melt and melting the binder onto the web by increasing temperature.
They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn.
