Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. WebSimilarly, for a cotton fiber of tenacity σ = 0.32 Ntex −1 and fiber density ρ = 1520 kgm −3, the mechanical (engineering) strength is σ* = 487 MPa. In case of using units of specific stress, we find that the polyester fiber has 33% higher tenacity than the cotton fiber.
