ABSTRACT: The carbon black has been
used in military fabrics to comply with the color requirements and infrared
radiation lessening criteria. Currently, military industries don’t distinguish
between fabrics with carbon black fibers or with carbon black into dyes or
prints. The latter initially allows us to comply with the color specifications
in the visible and infrared, but fabrics are degraded with use losing that
initial capacity. The inclusion of carbon black in the fiber gets that the fabric
doesn’t degrade with the wear, washed and dried, ensuring the
accomplishment of the specifications all the time. The use of infrared imaging
will allow us to define a method to discriminate those textiles with carbon
black in their fibers from those which are dyed or printed.
