microscopic analysis of fibers, yarns and fabrics.

The system is composed by:

- Leica Biological Microscope.

- Leica S tereo-Microscope.

- Professional colour Video camera with 1/2’’ CCD.

- Optical fibre illumination device (150W) with two 50 cm arms .

- «Mesdan Video Analyser» graphic card for images acquisition .

- S pecial «Mesdan Video Analyser» software.

- IBM Personal Computer.

- PHILIPS 17’’ LCD Monitor (or equivalent).

- EPSON STYLUS COLOR high quality printer.

- Sample preparation kit for longitudinal and sectional analysis (microtome, slides and
covers, immersion oil and other accessories)

- Fabric support kit for the analysis of irregularities in woven and knitted fabrics and for the
measurement of the weft and warp density per cm.

- Equipment functioning instructions and sample preparation literature.

- Calibration slide (for the system calibration control).

- Microsoft Office software package for the statistics processing and report production.

EQUIPMENT SUITABLE TO:

- Perform in a fast and easy way the fineness analysis of single fibres, by
operating with the live image and by means of the mouse only.

- Identify the different fibres contained in a blend and analyse the composition
percentage, by operating with the live image, in accordance with the IWTO 8, IWSTM
24, ISO 137, ASTM D2130 international standards.

fibre, to highlight how different fibres can

be easily detected.

- Check the purchased material (searching for possible foreign fibres) and identify
the type of fibre, comparing it with the fibre pictures stored in the DataBank, with both
the longitudinal and the sectional views.

- Analyse the yarn structure and detect possible defects. Check the single threads
of a twisted yarn; check the single yarn fibres.

- Measure the count of circular section yarns and filaments in Dtex or den .

- Check and measure the quality and shape of Lycra or synthetic multifilament single

threads.

- Detect, identify and measure possible impurities contained in textile materials
(neps, pollution due to foreign fibre content in a fabric, oil or grease content in a yarn).

- Analyse the compactness of non-woven fabrics.

- Perform a micro analysis of yarns and fibre sections.

- Measure section surfaces and perimeters.

- Analyse mechanical parts (i.e. needle points, spinnerets, etc).
