Fasertyp

Fasertyp, literally "fiber type" in German, is a general term used in technical and scientific literature to denote a category or class of fibers with shared characteristics. The exact meaning depends on the domain and context.

In textiles and materials science, Fasertyp describes the origin and composition of fibers used for textiles and composites. Natural fibers include Baumwolle (cotton), Wolle (wool), and Seide (silk); synthetic fibers include Polyester, Nylon, Polypropylen, and Aramid. Properties of a Fasertyp such as elasticity, tensile strength, moisture regain, and fineness influence processing, handling, and end-use performance.

In fiber optics, Fasertyp refers to categories of optical fibers, typically distinguishing einmodige (monomode) and mehrmodige (multimode) fibers, as well as core materials (silica, polymer) and refractive-index profiles (step-index, graded-index). The choice of Fasertyp affects bandwidth, attenuation, and transmission distance.

In neuroanatomy and physiology, Fasertyp describes classes of nerve fibers, often labeled A-, B-, and C-fasern. A-fasern are large and myelinated with high conduction speed; B-fasern are smaller and myelinated; C-fasern are unmyelinated and slower. These distinctions correlate with sensory and motor functions and with autonomic signaling.

In practice, Fasertyp informs specification, testing, and quality control across industries, and the term is often replaced by more precise descriptors such as Faserart, Faserklasse, or Typbezeichnung within standards and product catalogs.
