- Fibre testing can be like an ambush for the unwary. There is much misinformation as to what fibre test results mean and how they should be applied. The following is a short guide to help dispel some of these fibre testing myths. more »
- From the sample supplied to the testing laboratory, 2000 fibres are measured and then processed to obtain, mean (average) fibre diameter, standard deviation, co-efficient of variation, histograms comfort factor, coarse edge measurement, curve, curve standard deviation, and spinning fineness. more »

- Alpaca fibre has low crimp and smooth fibre surface. This makes the fibre difficult to process, particularly in sliver/fibre transferring and delivering processes. Blending with wool enhances the alpaca fibre processibility, makes the fibre more easily processed on modern wool processing facilities, and allows the development of new products. To evaluate the effect of wool fibre properties, especially wool crimp, on alpaca/wool blends, two alpaca fibre lots were processed to tops then blended with three commercial wool tops via top gillings. Yarns and knitted fabrics were subsequently engineered with identical machine settings. The performance of alpaca/wool blend slivers, yarns and fabrics has been investigated in this paper. more »
- The capability of instruments such as SIROLAN-LASERSCAN (LASERSCAN) and OFDA100 to provide measurements of fibre curvature has resulted in increased interest, within Australia among wool producers and exporters, and among overseas top-makers and spinners. However, the metrology of fibre curvature measurement by these instruments is poorly understood. Standardized conditions for preparation, and measurement procedures that stabilize the curvature of the wool fibres prior to measurement by either instrument, are yet to be defined. more »
