Bast Fibres

Bast Fibres
BAST FIBRES
The fibres obtained from the inner bark of flax, hemp, jute, ramie and other. plants and shrubs. True bast fibres are those of linen, hemp and jute, where the fibre occurs in the bast itself. All other bast fibres do not occur in the bast, but in single bundles in the leaf structure of the plant, and should be designated as sclerenchymous fibres. The bast fibres may be roughly divided into four classes with reference to the comparative sizes of the cell-wall and inner canal or lumen: - 1. The canal takes up about four-fifths of the diameter of the fibre : Ramie and China Grass. 2. The canal is about two-thirds of the fibre diameter : Hemp, Pita and Sunn Hemp, Pineapple Fibre. 3. The canal is mostly less than half the fibre diameter : Manila Hemp, Ambari Hemp, New Zealand Hemp, Yucca. 4. The canal is often reduced to a mere ???ine : Linen - (Mathews)
