Abstract
Abstract Process for the production of camouflage dyeings and prints on synthetic or regenerated fibers or foils or on blends containing synthetic or regenerated fibers, the dyed materials having infrared reflection values of from 20 to 50 percent within the infrared range between 700 and 1100 nm, by cross-dyeing or cover-printing fibers or foils made of the said materials and containing small amounts of carbon black as a mass coloration, with the dyestuff classes suiting the substrate concerned in shades that are suitable for camouflage colors in the visible range of the spectrum.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A process for the production of camouflage dyeings and prints on synthetic or regenerated fibers or foils or on blends containing synthetic or regenerated fibers to obtain dyed materials having camouflage properties in the visible range and infrared reflection values of from 20 to 50 percent within the infrared range between 700 and 1100 nm, which comprises the steps of: (a) providing fibers or foils containing small amounts of carbon black as a mass coloration; and (b) cross-dyeing or cover-printing the mass colored fibers or foils of step (a) with a dyestuff suited for the fibers or foils in shades that provide camouflage colors in the visible range of the spectrum.
Claim 2
Dependent Claim
111 words
A process for the production of camouflage dyeings and prints on synthetic or regenerated fibers or foils or on blends containing synthetic or regenerated fibers to obtain dyed materials having camouflage properties in the visible range and infrared reflection values of from 20 to 50 percent within the infrared range between 700 and 1100 nm, which comprises the steps of: (a) providing fibers or foils containing small amounts of carbon black as a mass coloration; and (b) cross-dyeing or cover-printing the mass colored fibers or foils of step (a) with a dyestuff suited for the fibers or foils in shades that provide camouflage colors in the visible range of the spectrum.
Claim 3
Dependent Claim
29 words

Claim 7
Dependent Claim
13 words
A process as claimed in claim 1 wherein the material is polyethylene terephthalate.
Claim 8
Dependent Claim
13 words
A process as claimed in claim 1 wherein the material is a synthetic.
