Cotton is grown all over the world, and each environment effects the cotton, well thats i was told years ago…
Each cotton has its Plus’s and Negatives… Ive been in brands that we ask the Denim Mills / suppliers to blend different types of cottons together, to make interesting cotton concepts exclusive to us.
Cotton is classified by the length and diameter of fiber and condition of the cotton. The longer the fiber the higher the rating it will receive. A smaller diameter fiber can be spun into finer yarn and thus is rated higher than a thicker fiber.
Cotton is also classed for its whiteness (middling) and how much debris is present. Whiteness is classified as extra-white, white, spotted, tinged, yellow stained and tray – personally i like it stained
Egyptian cotton is also known for a long staple (fiber) length, but has a very fine diameter. Which is a softer, more lavish material. Thus Egyptian cotton is known for bedding etc.. –
U.S.A. cotton or upland cotton, accounts for 90% of the worlds cotton. This type of cotton is known for its short-staple. In the 1700’s this type of cotton was then bred with Egyptian cottons to produce the contemporary ELS cottons “extra-long staple” thus 100% American Pima cotton was born. Pima cotton is controlled, and its grown in U.S., Australia, Peru and in very limited production in a few other places. ELS or American Pima has its strength / uniformity (its soft and strong from the Egyptian hybrid ). Thus are considerably higher than those of upland cotton.
Zimbabwean cotton, is regarded as one of the finest cottons in the world, and even more so as it becomes even scarcer as fewer farmers grow the plant. This is a long staple cotton. – No genetics – super irregular – perfect for hard core denim nerds – Most japanese Mills buy up most of the Zimbabwean cotton… combined with natural indigo, and super old shuttle looms, at dangerously low speeds – Theres a reason why japanese denim is the best –
There are many more interesting types of cottons, and blends, and some interesting concepts coming from Pakistan – no match to Zimbabwean cotton, but interestingly it was the Arabs who named cotton and it was the people of the Indus River Valley (Pakistan) who 1st spun it and woven into cloth.
