Patent ID: 8236714

Claim:
A fabric having a camouflage appearance in the near infrared (NIR) spectrum and having a uniform appearance in the visible (VIS) spectrum, the fabric comprising at least two types of synthetic polymer multifilament yarns, wherein the at least two types of multifilament yarns are selected from the group consisting of: a first type of multifilaments comprising carbon black in an amount of from about 10 parts per million to about 300 parts per million, a second type of multifilaments comprising pigments which modify a NIR reflectance characteristic of said second type of multifilaments, and a third type of multifilaments substantially free of additives capable of modifying the NIR reflectance characteristics of said third type of multifilaments; and wherein said fabric exhibits a single substantially uniform color appearance in the VIS spectrum of 400-680 nm and further exhibits a patterned appearance in the NIR spectrum of 700-900 nm due to different NIR reflectivities of the component multifilament yarns.
