What is non-woven?
    Non-woven fabric is a sheet or web structure, produced by interlocking layers or networks of fibers or filaments (and by perforating films) mechanically, thermally or chemically. It is flat, flexible and porous. Non-woven fabric mimics the appearances, textures and strengths of a woven fabric and can be produced as bulky as the thickest padding. Non-woven fabric is formed either by a one-step or two-step process. In the one-step process, the web formation and the bonding takes place continuously. A good example of one-step process is spunbond and melts blown process. In this process, the thermoplastic fibers are extruded through a spinneret and laid down on a convey or belt, which forms a web. The web is then bonded by passing the fibers between two calendar rollers. In melt blown process, the fibers are blown onto a collector screen to form a web. In the second process, the two-step process, a web is first formed and then bonded by a separate process. The web is formed by dry laid, air laid or wet laid method. Most of the web is fragile. To strengthen, the web is bonded by either an application of an adhesive, thermal exposure, needlepunching, hydroentanglement or stitchbonding.
