Hint: Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of cotton plants in the mallow family Malvaceae. The fiber is almost entirely composed of cellulose. Cotton bolls will aid in the dispersal of seeds in natural conditions.
Complete answer: Textile fibers of varying lengths are referred to as staples. A filament fiber, on the other hand, is available in continuous lengths. The staple length of a sample of staple fibers is a characteristic fiber length. It is an important criterion in yarn spinning because it aids in cohesion and twisting. Natural fibers have different and shorter lengths than synthetic fibers. The quality of natural fibers like cotton is categorized on staple length such as short, medium, long-staple and, extra long.
Cotton staples are lengths of cotton fiber. Cotton, as a natural fiber, comes in a variety of staple lengths. Long-staple cotton is derived from the cotton species Gossypium barbadense, which produces cotton with unusually long, silky fibers. This species is the source of well-known cotton varieties such as Egyptian cotton, Pima cotton, Supima cotton, and Giza 45. The best cotton for weaving quality cotton bed linen fabrics.
The length of medium staple cotton ranges from 2.2 cm to 2.8 cm. The staple length is the average length of a group of fibers that make up a cotton yarn. The longer fibers of extra-long-staple cotton produce stronger and softer yarn, resulting in stronger and softer fabrics.
Thus, The length of medium staple cotton ranges from 2.2 cm to 2.8 cm.
Note: Originally, cotton and wool staple lengths were measured by hand, with the tester removing a clump of fiber and arranging it on a dark cloth for measurement. Machines were invented in the 1970s to do this task, which took about 5 minutes for cotton and about 20 minutes for wool. Optical scanning methods such as digital fibrograph and HVI are now used to measure fiber length; they can measure the staple length efficiently.
