What is Pima Cotton? What is Supima Cotton? How does Pima cotton become Supima cotton? According to the different origins, cotton is mainly divided into fine-staple cotton and long-staple cotton. Compared with fine-staple cotton, the fibers of long-staple cotton are longer and stronger. The length of supima cotton is generally between 35 mm and 46 mm, while the length of pure cotton is generally between 25 mm and 35 mm, so supima cotton is longer than pure cotton;
Pima cotton grows in the southwest and west of the United States, which is one of the richest agricultural production areas in the United States, with extensive irrigation systems and suitable climate, long sunshine hours, which is very beneficial to the growth of cotton. Compared to other cottons, it has a higher maturity, longer lint and an excellent feel. In the global cotton production, only 3% can be called Pima cotton (the best cotton), which is hailed as “luxury in fabrics” by the industry.
Fine Staple Cotton – Commonly Used Cotton
Also called upland cotton. It is suitable for planting in the vast subtropical and temperate regions and is the most widely distributed cotton species in the world. Fine-staple cotton accounts for about 85% of the world’s total cotton output and about 98% of China’s total cotton output. It is a commonly used raw material for textiles.
Long-staple cotton – longer and stronger fibers
Also known as sea island cotton. The fibers are slender and long. In the process of cultivation, large heat and long periods are required. Under the same heat conditions, the growth period of long-staple cotton is 10-15 days longer than that of upland cotton, which makes the cotton more mature.
The advantages of pure cotton fabric are obvious. It has a balanced humidity and a moisture content of 8-10%. It feels soft and not stiff when it touches the skin. In addition, pure cotton has extremely low thermal and electrical conductivity and high warmth retention. However, there are also many disadvantages of pure cotton. It is not only easy to wrinkle and deform, but also easy to stick to hair and be afraid of acid, so you need to pay more attention to it every day.
Speaking of cotton fabrics, I have to mention the fact that the United States is restricting cotton in Xinjiang, China. As an ordinary person, I really feel helpless and angry that such a policy is made for political reasons. Whether there is forced labor in Xinjiang, I still hope that more people will come to Xinjiang to take a look and find out the truth for themselves.
