quel est le diamètre d'une microfibrille de cellulose?

Answer 1

By definition, microfibers are ultra-fine yarns made from various sources. They can be polyester, nylon, or a natural material such as cellulose. Microfiber is two times finer than silk and nearly one hundred times finer than human hair. In fact, many microfiber yarns are so fine that a strand stretching 25,000 miles around the earth will only weigh a few pounds.

Answer 2

Hmm, technically your question should be in English. Ask again on the French site. And I'd say less than 1mm probably - it's very thin.
