This textile is chemically organic, which means that it does not contain any synthetic compounds. The difficulty in analyzing cotton morphology arises from the fact that the plant simultaneously develops both vegetatively and reproductively. All plant metabolic reactions are dependent on this energy source. In flax, ramie, hemp, and other bast fibres, the spiral angle is small – less than 6° – so that these fibres are highly oriented and give high strength and low extensibility.
