Cotton Fabric Types

Cotton names can describe different things: the plant variety, the fiber quality, or the construction of the cloth. Pima and Supima concern the fiber, while lawn and chambray describe fabrics made from yarn. Separating those layers makes comparisons more useful than placing every cotton name in one undifferentiated list.

An extra-long-staple cotton

Supima is associated with extra-long-staple Gossypium barbadense cotton. Long fibers can be spun into smooth yarn with fewer exposed short ends, helping explain the softness and resistance to pilling that make the material popular for clothing and sheets. The fiber itself does not dictate whether a finished fabric is knitted or woven.

Cotton Fabric Types: Understanding the Supima Cotton Designation

A name with a specific meaning

Supima is a trademarked designation connected with American-grown cotton and an industry certification system. Pima is the broader related term, so a product should not be described as Supima merely because its fabric feels soft. The distinction is useful when reading product descriptions: a recognized fiber name conveys information about origin and verification as well as the expected handle.
