Abstract
A modified synthetic polymer filament and multifilament yarn of polyamide or polyester filament containing a carbon black polymer additive, and fabrics from these yarns, are disclosed. These melt spun filaments are especially well-suited for use in garments and equipment where a modified Near Infrared Reflectance (NIR) signature is desired. The yarn and fabrics made from this yarn may be advantageously dyed or printed to provide a camouflage fabric for use in desert sand dominated environments, urban environments and multi-terrain environments.
Claims14
A polymer filament having IR reflectance in the range of 600 nm to 900 nm of 20% to 65% comprising:
- about 10 to 300 p pm carbon black;
- and
- polymer,
- wherein the polymer filament further comprises one of a circular, trilobal or diabolo profiled cross-sectional shapes, wherein further the polymer comprises polyamide or polyester of about 0.7 to about 8 dpf, wherein further the polymer filament has near infra-red reflectance in the range of 600 nm to 900 nm of about 20% to about 65%.
