Non Woven, Fleece, needle felt | clouds, neps in card pile
The area microscope Roboscope aquires images up to 200x300mm at a resolution of 10mµ. Based on image inspection results, it calculates a key figure for the cloudiness or homogeneity. This number indicates how evenly the fiber distribution is in needle felts and other nonwovens.
# 1 raw image of card pile
Visable sample sice 100x70mm
# 2 clouds recognized, calcuation of homogenity
The software calculates the amound of clouds formed by neps and uneven fiber distribution. A quality index number for average cloudiness is determined, this can be done for samples up to 0.1m² in size.
# 3 needle felt evenness?
The red dots show the needle penetration points found by the image recognition software.
