Compared to SEM, the primary advantage of the optical cashmere microscopic test is that the operative can see the internal structure (or pigments) of the fiber. These features can help to differentiate the cashmere from any lower value substitute fibers (e.g. wool, yak) that a third party may have introduced at some point along the processing chain.
The optical method relies on operatives identifying magnified fibers from their scale structure and other features. We follow the relevant methodologies set out by:
Given that there are overlaps in the characteristics of cashmere and other wool fibers, using an optical microscope to measure such materials is a somewhat subjective process. To maintain consistency and accuracy in our cashmere microscopic analysis, we only use industry-accepted methods and provide our operatives with standardized training, based on our traceable animal fibers library.
We have also centralized the operation of our speciality animal fibers testing services in the UK. Approved by the Cashmere and Camel Hair Manufacturers Institute (CCMI), this facility is constantly involved in the development of:
