What is Non-Woven Fabric?

We always heard of non-woven bags. Most famous for its durability, strength and eco-friendliness since it is re-usable. But what is it actually made-off?

Well, nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally or chemically. 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. Typically, a certain percentage of recycled fabrics and oil-based materials are used in nonwoven fabrics. The percentage of recycled fabrics vary based upon the strength of material needed for the specific use.

Nonwoven fabrics are engineered fabrics that may be a limited life, single-use fabric or a very durable fabric. Nonwoven fabrics provide specific functions such as absorbency, liquid repellency, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, bacterial barrier and sterility. These properties are often combined to create fabrics suited for specific jobs, while achieving a good balance between product use-life and cost. They can mimic the appearance, texture and strength of a woven fabric and can be as bulky as the thickest paddings. In combination with other materials they provide a spectrum of products with diverse properties, and are used alone or as components of apparel, home furnishings, health care, engineering, industrial and consumer goods.

Non-woven materials are used in numerous applications, including:

Hygiene

Medical

  • isolation gowns
  • surgical gowns
  • surgical drapes and covers
  • surgical scrub suits
  • caps

Filters

  • gasoline, oil and air – including HEPA filtration
  • water, coffee, tea bags
  • pharmceutical industry
  • mineral processing
  • liquid cartridge and bag filters
  • vacuum bags
  • allergen membranes or laminates with non woven layers

Geotextiles

  • soil stabilizers and roadway underlayment
  • foundation stabilizers
  • erosion control
  • canals construction
  • drainage systems
  • geomeambranes protection
  • frost protection
  • agriculture mulch
  • pond and canal water barriers
  • sand infiltration barrier for drainage tile

There is even an association dedicated to this kind of fabric, Association of the Non-Woven Fabrics Industry. You can view their website at www.inda.org.
