How to Choose the Most Suitable Fiber Fineness Analyzer Based on Fiber Type

Selecting the right fiber fineness analyzer depends largely on the type of fiber being tested. Different fiber materials require different measurement technologies to ensure accurate, reliable, and repeatable results.

1. Match the Analyzer to the Fiber Type

Animal Fibers

For animal fibers such as wool, cashmere, and rabbit hair, it is recommended to choose a Wool Fiber Fineness Analyzer equipped with cross-sectional analysis capabilities. This type of instrument can accurately measure hollow or irregular fiber structures, overcoming the challenges associated with complex natural fiber morphologies.

Synthetic Fibers

When testing man-made fibers, priority should be given to analyzers with advanced recognition algorithms capable of identifying special cross-sectional shapes, such as trilobal, flat, or other profiled fibers. This ensures accurate diameter measurement regardless of fiber geometry.
