What Is Long Staple Cotton?

Long staple cotton is named for its longer fiber, and is also called island cotton. It is a cultivated cotton species belonging to the genus Malvaceae. The growth period of long-staple cotton is long and requires a lot of heat. Under the same heat conditions, the growth period of long-staple cotton is 10-15 days longer than that of upland cotton.

Morphological Characteristics

Long staple cotton is of good quality, its fiber is flexible and long, generally 33～39 mm, the longest can reach 64 mm; the fineness is 7000～8500 m/g, the width is 15～16 microns; the strength is 4～5g Force/root, fracture length is 33-40 kilometers; there are many turns, 80-120/cm.

There are some hybrid varieties with sea island cotton as male parent and upland cotton as female parent. They have longer fibers, but their fineness and strength cannot reach the indicators of sea island cotton. They are commonly called long-staple cotton.

Classification

Extra-long staple cotton: The fiber length is more than 35 mm.

Medium-long staple cotton: The fiber length is 33 to 35 mm.

It was a new variety introduced in the early 19th century by the Egyptian ruler Muhammad Ali to adapt to the rapid development of the industrial revolution in European countries and the demand for cotton and other raw materials. After a long period of breeding and domestication in Egypt, it has good quality, high yield and the widest planting area.

There are many varieties of long-staple cotton cultivated in various countries in the modern world, including Egypt’s "Jiza 45" and "Jiza 70"; Sudan’s "Vias" and "Barakat"; Soviet Union’s "6465 Ephraim" and "9647" "Yi"; there are also varieties such as "Bima" from the United States, Peru and Morocco.
