Faserreste

Faserreste are small fragments or fibers that remain after the processing, use, or degradation of a fiber-based material. They occur in a wide range of contexts, including textiles, paper and pulp, wood products, and polymer composites. These remnants can consist of natural fibers such as cotton or wool, synthetic fibers such as polyester or nylon, or blends, and they may vary in length, thickness, and surface condition.

In textiles, Faserreste are generated during spinning, weaving, dyeing, and finishing, as well as through wear and laundering of products. In paper and pulp production, they appear as fines or short fibers resulting from mechanical or chemical processing of wood and recycled fibers. In composite materials, residual reinforcement fibers can remain after trimming, machining, or weathering. The presence and characteristics of Faserreste influence material properties such as strength, texture, and recyclability, and they affect waste streams and quality control.

Analysis of Faserreste commonly relies on microscopy (optical or scanning electron), image analysis to quantify fiber content and length distribution, and spectroscopy or chemical analysis to identify fiber types. Sample preparation may involve disintegration of the matrix, mounting, or etching, depending on the material.

In practice, understanding Faserreste supports material characterization, recycling optimization, and forensic or archaeometric investigations by providing information about manufacturing processes, fiber provenance, and aging behavior.
