Natural Fibers and Fabrics Information

DescriptionNatural Fibers and Fabrics Information


Natural fibers and fabrics consist of bulk fibers, yarns, or woven cloth manufactured from plant materials such as:

  • Cotton
  • Wool
  • Linen (flax)
  • Sisal
  • Jute
  • Hemp
  • Silk
  • Blended fiber



Bulk chopped fibers or thin, continuous fiber filaments are used typically in composite reinforcement applications, flowable insulation, or as the key component in woven fabrics, braids, knits, rope roving or other specialty fabrics.


Roving is made of tows, untwisted bundles of continuous filaments.


Yarn is made of continuous, often plied strands of natural fibers and fabrics.

Natural Fibers and Fabrics Information 

Carded and needlepunched nonwovens offer very high loft (low density) at very low cost. 


Braided products are used in tubular composite structures, thermal insulation fabrics, and many other applications.


Cordage is a generic term that covers various types of cords, lines, ropes, and strings. Rope is used in material handling, shipping, construction, logging, and marine applications. 


Webbing is a textile product that is supplied as a woven ribbon, strapping, or tape. Webbing unravels when cut, a feature which distinguishes it from cordage and rope.


Threads are thin, continuous threads or filaments are used for stitching or reinforcement. These natural fibers and fabrics include both monofilaments and multi-fiber threads.
