Precision Fiber Microtome is used to make accurate cross-sectional specimens of fiber for further examination under a microscope.vb2Textile Testing Instruments, Testing Equipment Manufacturer
A bunch of defatted fiber is inserted into the slot on the top of the Microtome. An embedding medium is applied to the bundle and allowed to dry. The fiber bunch is placed on the ejector and the micrometer wheel is used to determine the required parameters of the precision cut.vb2Textile Testing Instruments, Testing Equipment Manufacturer

Cross-sectioning reveals certain characteristics that may be used to identify fibres, including:vb2Textile Testing Instruments, Testing Equipment Manufacturer
1. Contour of the fibre.vb2Textile Testing Instruments, Testing Equipment Manufacturer
2. Thickness of the cuticle layer.vb2Textile Testing Instruments, Testing Equipment Manufacturer
3. Presence of medulla ndash; if present, its type, shade, contour in relation to that of the fibre, and position in the fibre.vb2Textile Testing Instruments, Testing Equipment Manufacturer
4. Presence of pigment ndash; if present, its distribution whether it is sparse, dense or in large aggregates, and whether it is most dense near the medulla or near the cuticle or arranged in bi-lateral form.vb2Textile Testing Instruments, Testing Equipment Manufacturer
5. Dye penetration.vb2Textile Testing Instruments, Testing Equipment Manufacturer
