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.
