What Is Supima Cotton?

Cotton Boll - What Is Supima Cotton

Supima is a portmanteau of supreme and pima. So to understand what is Supima cotton, we first have to know what is Pima cotton. Pima cotton is a long or extra-long staple cotton. It grows in only a few areas of the world: Peru, the USA and Australia. Supima cotton is a special type of pima cotton that comes only from the USA. But not all US-grown pima cotton is considered superior. True Supima cotton bears the Supima® trademark.

Where Does Supima Cotton Come From?

The first half of the 20th century saw a rise in the demand for pima cotton. A group of US family farmers decided that the quality of the cotton must not suffer due to the higher demand. So in 1954 they established the Supima non-profit organization. To goal was to group pure and high quality pima cotton in the US. To better manage and promote Supima cotton, they started a license program. These days the Supima® trademark is quite an exclusive club. Only around 600 select US manufacturers and retailers have the license.

Supima cotton needs a hot arid climate and irrigation to grow. So only a few areas in the US, like the Southwest and Far West, are suitable for cultivation. Of all the cotton grown in America, pima cotton makes up around 3%. The number of licensed Supima manufacturers and retailers is quite small, as we saw above. So Supima cotton is even more rare.

What is Supima Cotton Like?

Supima cotton is special, as it comes strictly from the USA. But apart from that, this cotton type shares other characteristics of pima cotton. Most importantly, this cotton has long or extra-long staple fibers. Staple refers to the length of an individual cotton fiber. This determines much of the quality of the fabric. Fibers can be short, medium, long, or extra-long.

Table of Staple Length Classification - What Is Supima Cotton

Long stable cotton fibers are at least 1.3/32 long. While extra-long staple means that the cotton fibers are at least 1.3/8 inches long. Long and extra-long staple fiber makes for better quality sheets. This is because there are less fiber ends sticking out from the fabric. You just don’t need that many fibers to sow into a sheet in the first place. Although tiny, these ends make the fabric surface less smooth and soft. The other reason why you should prefer sheets from longer staple cotton, is because they are less prone to pilling. Which also makes them more resistant to tearing or breaking.

What Is Supima Cotton Used For?

Supima cotton is most widespread in the clothing industry. You can find men’s and women’s shirts, denim, t-shirts, socks, shorts, pants, and other apparel. But not only that. Supima cotton is also used for making other products. Such as bed linen, towels, bathrobes, and even furniture.
