  • Relationship of Ortho-Cortex to the Crimp Wave in a Double-Crimped Wool

    The cortex of a crimped Merino wool fibre comprises two hemi-cylinders, which differ in both chemical and physical properties. The form of the crimp wave is related to alternations in the positions of the two cortical components within the fibre—the ortho- and the para-cortex1–4. The ortho-cortex tends to lie on the convex aspect of the crimp wave and the para-cortex on the concave aspect. more »
  • How important is Fiber Quality in Alpacas?

    Crimp is related to the fibers as they appear in an intact lock. Its measured in waviness per unit of length. The prevailing theory is the greater the crimp, the finer the fleece. Cameron pointed out this isn't always the case, however. Many Peruvian alpacas have recently been examined that have little or no crimp, but very fine fleeces. more »
  • Don't Let Micron Madness Crimp Your Style

    Everyone who comes on the farm these days is concerned about two items - micron count and crimp. I, myself, have written much about the virtues of skinny fleece and bold crimp, so I began to ponder whether this narrow focus was all that healthy for our industry. more »
  • Alpaca Fiber Facts

    My goal is to breed alpacas with the fineness of cashmere and the crimp of merino. Fineness is measured in microns and finer fiber has a smaller micron count. As an example, human hair can have a micron count of 40-80+ while most cashmere is in the 15-19 micron range. Alpaca fiber can range from 15 -40 microns—depending on their breeding and age—with younger animals having the finest fiber. more »
  • How to Evaluate Alpaca Fiber

    There are no perfect alpacas. There is great room for improvement in all of our herds, and we can watch it happen before our eyes in our very own pastures, when we make good breeding choices. Once you learn to judge alpaca conformation and fleece, you'll see that not even blue ribbon winners are perfect. Learning to evaluate fleece will help you to make the best breeding choices for your alpacas. more »
