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.
