Study on the Thick Tip of Lamb's Wool of Superfine Merino Sheep
|
Abstract Superfine wool of Merino sheep has many distinct characteristics, especially its higher fineness. Generally, its mean diameter is about 16.5 µm and it is a good material for fine worsted fabrics. However, the region near the tip of a primary fiber has a coarser fiber diameter, with a value of 35-66 µm. The length of such a segment is usually up to 16-22 mm. The secondary fiber also has a small swelling segment near the tip, but the length of this segment is very short and difficult...

Measurement Precision and Evaluation of the Diameter Profiles of Single Wool Fibers
Textile Research Journal
; Abstract A recent model of the Single Fiber Analyzer 3001 (SIFAN3001) was firstly employed to obtain the single wool fiber diameter profiles (S^sub f^FDPs) at multiple orientations. The results showed that using SIFAN3001 to measure fiber diameter at four orientations for 50 single fibers randomly
