Economic Uses of Malvaceae - Fibre Crops

Ernest Goulding, Cotton and Other Vegetable Fibres - Their Production and Utilization (reprint? 2007)

The most important crop is cotton, which is obtained from the seed hairs of 4 species of Gossypium, the Old World diploids Gossypium arboreum and Gossypium herbaceum, and the New World tetraploids Gossypium hirsutum and Gossypium barbadense. Cotton is the world's preeminent natural fibre, of which in excess of 20 million tonnes are produced annually. This dwarfs the production of animal fibres (wool, about 1½ million tonnes annually) and is comparable to the total production of synthetic fibres. The largest producers are China, the United States of America, India and Pakistan. Production is also extensive in Central Asia, the Middle East, Australia, Brasil, and Mediterranean Europe.

Jute, obtained from the phloem fibres of white jute, Corchorus capsularis and red or tossa jute, Corchorus olitorius, is also an important fibre crop; with a production in excess of 2 million tonnes annually it is the second largest vegetable fibre. India and Bangladesh are by far the largest producers. Kenaf, obtained from the phloem fibres of Hibiscus cannabinus, has an annual production of about 1 million tonnes. Thailand, Burma, China and Bangladesh are the major producers.

Several other species are exploited for their phloem fibres, including devil's cotton, Abroma angusta, China jute, Abutilon theophrastii, roselle, Hibiscus sabdariffa and bast, Tilia sp., and many others are or were used at the subsistence level.

Kapok, the seed hairs of a number of trees belonging to Bombacoideae, particularly Bombax ceiba (250,000 tonnes annually), is not spinnable and therefore can't be used for textiles, but is waterproof. It is used primarily for insulation.
