What is non-woven fabric? Describe the Characteristics of non-woven fabrics.

Non-woven fabric:

Non-wovens are a sheet, web or bat of natural and or manmade fibres or filaments, excluding paper, that have not been covered into yarns, and that are bonded to each other by any of several means.

Non wovens are flexible porous product consisting of one or more fibre layers. The separate fibres may either be preferentially oriented in one direction or may be deposited in a random manner. They are bonded by chemical, thermal or mechanical processes into textile products. Non woven are mainly planner structures.

This relatively young branch of textile industry has expanded enormously after the Second World War, because of the high production rates & the resulting cost savings.

Characteristics of non-woven fabrics:

The particular set of properties that a non-woven fabric may have is dependent upon the combination of factors in its production.

The range of characteristics is wide. Some characteristic is given below:

  • The appearance of non-woven fabric may be paper like, felt like or similar to that of woven fabrics.
  • They may have a soft, resilient hand or they may hard stiff or board with the little pliability.
  • They may be as thin as tissue paper or many times thicker.
  • Non woven may be translucent or opaque.
  • Their porosity may range from high, free air flow to minute to impermeable.
  • Their strength may range from low tear & burst strength to very high tensile strength.
  • They may be fabricated by gluing, heat bonding or sewing (punching).
  • The drivability of non-wovens varies from good to none at all.
  • Some non-wovens have excellent launder ability, others have none. Some may be dry-cleaned.
