Facilidade de uso


-Leica Stereo-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 . - Special «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. Longitudinal image of a cotton and a wool 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. Viscose fibre in longitudinal and sectional view. Longitudinal and sectional view of a glass fibre. -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). Example of spinnerets Example of a nozzle of a splicer mingling chamber. Example of spinning rings -Perform a macro analysis of a yarn section. Example of an indigo dyed yarn section, extracted from a denim fabric - Reduce the fabric warp and weft density to a cm or a inch. The operator simply traces a reference line of desired length on the warp and weft and identifies the number of threads. The «Mesdan Video Analyser» software automatically determines the number of threads per cm (and inch). The collected data are automatically exported onto an excel sheet that produces a report with the thread reduction each cm (and inch). -Process, store and print the produced measurements and the minimum, medium and maximum values, CV% and distribution graphs. I.e. count analysis of a circular section fibre, in tex and den: data are automatically processed; the report can be either printed or stored. MESDAN VIDEO ANALYSER DATA: 15/02/2005 Note: Use it ONLY if you are sure that the section of the fiber is circular. Importante:Da utilizzare SOLO se si e certi che la sezione delle fibre sia circolare.
