Carpet Backing Cloth

About Carpet Backing Cloth

  • A carpet is used as a floor covering & usually it is made in hand loom by simple woven process.
  • The international carpet market for household and industrial end use is dominated by several types of carpet such as
  • Hand Knotted Carpets,
  • Hand Woven Carpets,
  • Tufted carpets,
  • Needle felt carpets,
  • Flat weave carpets, etc.
  • Carpet Backing Cloth (CBC) is used as the backing material for both woven and tufted carpets.
  • CBC is generally classified into two categories:
  • Primary Carpet backing: It is the base fabric on which pile yarns are tufted and fasten to make a carpet
  • Secondary Carpet backing: Here the fabric is bonded on the backside of the carpet to form an underlay.
  • Primary backing is used for making the carpet in which yarn is woven or tufted.
  • Carpet after being dyed is sending for secondary backing. Here the surface is smoothened and backing is applied.
  • Latex is applied on the back of the carpet by passing the carpet through the puddle of latex.
  • Latex is enforced downward by the cutting edge around all the yarn on the back of the carpet, which locks the yarn into the backing.
  • A 2nd cover of latex is applied after that for griping the secondary backing on top of the tufted material.
  • The purpose of the secondary backing is to give dimensional firmness while fasten individual tufts in place.

Product Characteristics

  • Primary backing is manufactured mainly from synthetic fabric.
  • Secondary backing is prepared of both jute and woven polypropylene.
  • Jute carpet backing cloth is roughly 104" wide with gsm changeable between 180 and 407.
  • Jute backing has certain limitations such as potential for browning and rotting.
  • Thus, the secondary backings used today are majorly woven polypropylene made of a leno weave of slit film and spun olefin yarns that forms a stretchable secondary backing fabric.
  • Synthetic carpet backing cloth is available in many varieties of which some are:
