Non Woven, Fleece, needle felt | clouds, neps in spun bond and card pile
The area microscope Roboscope aquires images up to 200x300mm at a resolution of 10µm. Based on image inspection results, it calculates a key figure for the cloudiness or homogeneity for card pile, rolled up pile, fleece, spunbond or meltblown. This number indicates how evenly the fiber distribution is in needle felts and other nonwovens.
# 1 raw image of card pile
Visible sample size 100x70mm
# 2 clouds recognized, calculation of homogeneity
The software calculates the amound of clouds formed by neps and uneven fiber distribution. The quality index number for average cloudiness 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.
