Cellulose Fibres - Bast Fibres

HideShow resource information

Introduction to Bast Fibres

  • Bast fibres/skin fibres are plant fibres collected from the phloem/bast/skin (the 'inner bark') surrounding the stem of certain plants.
  • Some bast fibres are cultivated, such as flax, hemp and ramie. Bast fibres can also come from wild plants like stinging nettles and lime trees.
  • Often, bast fibres have higher tensile strength than other cellulosic fibres and are used in high quality textiles (sometimes blended with cotton or synthetic fibres).
  • Ropes and burlap are examples of products produced from bast fibres.
  • Bast fibres contain structure called a fibre node that represents a weak point in the fibre. Fibre nodes are only present in bast fibres.
