Species Identification
Proteomic analysis of the rare hair harvested from wild Andean camelids confirms the authenticity of the most expensive natural fiber in the textile trade. This laboratory procedure, referred to as vicuña profiling, identifies the unique keratin sequences that distinguish this premium fiber from alpaca, llama, and cashmere. Importers use these testing reports to prove that high-value garments comply with international trade laws and authenticity standards.
The analysis protects buyers from purchasing mislabeled goods.
Authentication Method
The process begins by extracting the keratin from a small fabric swatch and digesting it into peptides. Mass spectrometry is then used to detect the unique amino acid markers that are specific to the vicuña species. This method is highly reliable even when the fibers have been dyed or blended with other materials.
Adulteration Prevention
Because vicuña fiber is extremely expensive, it is a frequent target for blending with cheaper fibers like fine alpaca or merino wool. This molecular profiling detects even small percentages of these adulterants, ensuring that the yarn is pure. It provides a level of certainty that simple visual inspection cannot match.
Market Protection
Maintaining the purity of this fiber protects the heritage and income of the communities that harvest it under strict conservation rules.
