    • A fabric having a camouflage appearance in the near infrared (NIR) spectrum with a substantially a single color appearance in the visible (VIS) spectrum is provided. The novel fabric may include at least two synthetic polymer multifilament yarns. The multifilament yarns are selected from 3 types of multifilament yarns: multifilaments comprising carbon black, multifilaments comprising pigments which modify the NIR reflectance characteristics of the multifilaments, and multifilaments substantially free of additives capable of modifying the NIR reflectance characteristics of the multifilaments. The fabric is dyed to a substantially single color appearance in the visible spectrum. In general, the fabric has a NIR spectrum comprising two reflectance curves having about 10% to about 85% reflectance separated by about 5% reflectance in a range of wavelengths from about 700 to about 860 nanometers (nm).The fabric may be used to manufacture garments, equipment, tents and tarpaulins that exhibit a camouflage appearance in NIR reflectance observed using night vision devices. At the same time, these garments, equipment, tents and tarpaulins have a single color and substantially non-camouflage in the VIS reflectance spectrum.
    • 提供了在可见光(VIS)光谱中具有基本上单一颜色外观的近红外(NIR)光谱中具有伪装外观的织物。 新型织物可以包括至少两种合成聚合物复丝纱线。 复丝纱线选自3种复丝纱线:包含炭黑的复丝,包含改变复丝的NIR反射特性的颜料的复丝,以及基本上不含能够改变复丝的NIR反射特性的添加剂的复丝。 织物在可见光谱中被染色成基本单色的外观。 通常,织物具有包括两个具有约10%至约85%反射率的反射率曲线的近红外光谱,所述反射率曲线在约700至约860纳米(nm)的波长范围内分开约5%的反射率。 织物可用于制造使用夜视装置观察到的在近红外反射中伪装外观的服装,设备,帐篷和防水油布。 同时,这些服装,设备,帐篷和防水油布在VIS反射光谱中具有单色和基本非伪装。
