How has mass production limited the value of fiber evidence?

Mass production has limited the value of fiber evidence by creating a vast array of similar fibers that can easily be found in multiple locations, making it difficult to link a specific fiber to a crime scene. The widespread availability of synthetic materials means that many fibers may not be unique to a particular source, reducing their evidentiary significance. Additionally, the sheer volume of fibers produced complicates the process of forensic analysis, as distinguishing between common fibers becomes increasingly challenging. As a result, while fiber evidence can still be useful, its ability to provide definitive links in investigations has diminished.
