纤维
维基百科，自由的百科全书
纖維是指由連續或不連續的細絲組成的物質，例如麻繩。 Fibers are often used in the manufacture of other materials. They can be spun into filaments, thread, or rope. They can be used as a component of composite materials. They can also be matted into sheets to make products such as paper or felt.
Fibers come from a wide variety of sources:
- Natural fiber include those made out of plants, animal and mineral sources.
- Natural fibers can be classified according to their origin.
-
- Vegetable fibers generally comprise cellulose: examples include cotton, linen, jute, flax, ramie, sisal and hemp. Cellulose fibers serve in the manufacture of paper and cloth.
- Animal fibers include spider silk, sinew, hair, and wool.
- 礦物纖維，例如石棉，由非有機物質組成. 石棉是維一自然存在的礦物纖維
- 人造纖維，是指經加工過而製成的纖維，包括玻璃纖維、尼龍等
- Synthetic fibers are a subset of man-made fibers, which are based on synthetic chemicals rather than arising from natural chemicals by a purely physical process. Such fibers are quite often made from nylon, polyester, or acrylic polymers, although pure polyacrylonitrile fibers are mostly used to make carbon fiber. More exotic fibers have strong bonding between polymer chains (i.e. aramids), or extremely long chains (i.e., Dyneema). Elastomers can even be used, i.e. in spandex.
