Identification of Carbon Black in Military Textiles Using Infrared Imaging Techniques

Abstract

<p> <span style="font-family:Verdana;">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</span><span style="font-family:Verdana;">’</span><span style="font-family:Verdana;">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.</span><span></span> </p

Comfort and reflectance properties of viscose/polyester blend fabric printed by vat/disperse dyes in visible/near‐infrared region

“…Fabrics treated with dyes or stampings including carbon black will lost such treatment due to use, washing and drying, thus losing their ability to absorb the infrared radiation. However, if the carbon black is inserted into the fibers forming the fabric it will not be degraded or eliminated with the uniform wear …”

“…However, if the carbon black is inserted into the fibers forming the fabric it will not be degraded or eliminated with the uniform wear. 19 Besides, vat dyes are the other useful dyes for camouflage textiles. 20 Based on the natural objects, the most visible colors for camouflage patterns are olive green, brown, khaki, and black.…”
