The difference between cellulose and cellulose fiber

Cellulose is called cellulose in English, which is a chemical name, referring to natural polymer materials connected by glycosidic bonds with glucose units.

Cellulose fiber is also called renewable cellulose. Cellulose fiber, of course, means that its chemical composition is cellulose, and its shape conforms to the definition of standard fiber.

Therefore, there is this kind of confusion. Since cellulose is usually fibrous, that is, slender, it is very easy to call it fiber, but don’t forget that the material contained in fiber is not only cellulose. When it is fibrous, such as degradation, dissolution and regeneration, etc., when its morphology has long been out of line with the concept of fiber, we cannot call it cellulose fiber, only cellulose.

Fibers include natural fibers and chemical fibers, and natural fibers include plant fibers and animal fibers, and chemical fibers include man-made fibers and synthetic fibers.

Plant fiber is composed of cellulose, hemicellulose and lignin and other small amounts of impurities.

The cellulose fibers are natural and renewable.
