- 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.

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).
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.

- The mentioned dimensions and final magnifications also depend on the hardware in use.
- The above mentioned magnifications and fields of vision have been calculated by using a 17” monitor with 1280X1024 resolution.
PROFESSIONAL VIDEO-CAMERA with 1/2’’ CCD;
compared to the 1/3’’ CCD, it has a much wider field of vision –
hence a wider surface of the sample is visualised – and a
quicker reaction to light variations. Complete with achromatic
C step connector with 1:1 lens, for the insertion on the
microscope, to give the maximum contrast, colour and planarity
quality.

MESDAN VIDEO ANAL YSER SOFTWARE
High flexibility to perform
measurements on stored
images as well as on live images
(in accordance with International
Standards).
Measurements of lengths,
surfaces, perimeters, angles,
distances between two points
or lines or objects.
The software allows to save a
picture (complete with
measurements and comments)
into the Data Bank and to
compare the live picture with a
stored one (or more
simultaneously).
It is possible to attach to the image an informative chart, containing the material composition,
the type of lens in use and other information; this chart can be opened with a simple mouse
click and can be printed together with the picture.
All the measurements can be exported into an Excel template for the data processing (and to
produce statistics and comparative graphs). The operator can also create self-made Excel
templates, according to his requirements.
Languages in use: Italian, English, Spanish, Portuguese and Polish.
The software is provided with a readyto-use Excel template to perform on 5
different materials: fibre % content in a
blended yarn; perimeter and surface
calculation; count measurements on
perfectly circular section yarns; fabric
warp and weft density reduction to cm
or inch; general counting on lengths.
The obtained data allow to produce
reports with statistics (CV%, mean
values, percentages, etc) and
comparative graphs, that can be either
printed or stored.
Fineness analysis of a blend with 3 components
1) Window to display the live picture: it is possible to store and/or print a picture complete
with comments and measurements. It is then possible to perform measurements and
send them to an Excel template in order to obtain statistics.
2) View finder window on the area where measurements are being taken, in order to
guarantee the maximum measure accuracy.
3) Material chart: the name of the material to be tested is inserted here (the measurements
on the picture will be expressed in different colours); if necessary, the measurements
of every material will be inserted automatically in different Excel columns.
The simple and intuitive application bar makes the software easier to use also for less expert operators.
The software includes a Data Bank with reference pictures that can be
personalised according to the user’s needs.
In order to help the operator and guarantee the maximum accuracy, different special
features are available: i.e. light and colour adjusting can be made digitally through the
software (as well as mechanically, by operating on the microscope filters).
