Definitions
- the present invention relates to a camouflage fabric with near infrared ray reflectance adjusting characteristics, and more particularly, to a camouflage fabric with near infrared ray reflectance adjusting characteristics, which can solve secession of application chemicals when a near infrared absorbing pigment or a carbon compound is coated on a synthetic fabric in a typical camouflage fabric manufacturing method, by weaving a camouflage fabric having a camouflage performance against a near infrared observation sensor using a conductive yarn containing copper sulfide nanoparticles or metal sulfide nanoparticles including copper sulfide, and has a Near Infrared Ray Reflectance (NIRR) that is identical to or similar to colorful natural backgrounds in the spectral reflectance in a near infrared spectrum in which a near infrared ray wavelength band ranges about 720 nm to about 1,500 nm.
- NIRR Near Infrared Ray Reflectance
- the camouflage fabric which has superior physiochemical properties and naturally exhibits antimicrobial properties and antistatic properties even without a separate post-treatment, can be provided.
- the probability of military personnel, vehicles, equipment, structures etc., so called ‘targets,’ surviving in the battlefield is directly related to the capability of responsive measure that can minimize all threats thereto.
- camouflaging One of the important responsive measures of the target against the threat thereto is camouflaging, such that it will be difficult for the enemy to detect the existence of such target.
- clothes In order for the target to conceal itself from the detection by a near infrared ray observation device at night, clothes must camouflage itself by having an equal or similar level of near infrared ray reflectance to those of surrounding objects, within the near infrared ray wavelength region of 720 nm to 1,500 nm, whereas the effective camouflaging to avoid detection by naked eye or visible ray detection equipment during the day can be achieved by applying a color camouflage that is performed in 380 nm to 720 nm spectrum, i.e., visible ray region.
- clothes in order for a camouflage to be equally effective at both day and night, clothes must have the pattern, color, brightness and chroma resembling its surroundings, which will successfully conceal the target by making it difficult to be detected within the area of visible ray during the day, and clothes must have the level of near infrared ray reflectance equal or similar to those of the surroundings, in consideration of the near infrared ray wavelength region used by the near infrared observation device used at night.
- camouflaging materials including both visible and invisible
- camouflaging materials used by military in the visible ray region and in the forest usually use four colors of black, brown, green and bright green.
- camouflaging materials in the desert during the day, usually use three colors of brown, khaki and yellowish brown.
- the fibers with camouflaging patterns for visible ray environment are typically manufactured by printing the camouflaging patterns on the surface of undyed greige fiber or by solution-dyeing the spun yarn that is successively woven or knitted into the camouflaging patterns by, e.g., a jacquard process.
- the materials must be processed differently from those in the visible ray region, to avoid the detection by near infrared observation devices during a night combat.
- the near infrared camouflage fabric which means an invisible camouflaging material for the night time, means a fabric that allows a wearer to avoid detection by near infrared night observation device by allowing the fabric to have a near infrared ray reflectance similar to that of its surrounding environment.
- This fabric has a very important value in the modern war due to the development of near infrared night observation devices.
- a method of manufacturing a typical near infrared camouflage fabric is as follows.
- a printing process is performed on a fiber that is not dyed by an existing method or dyed in base color to achieve a level of both near infrared reflectance and color for day and night times.
- the near infrared reflectance of fiber is changed by adding an adequate amount of carbon black and near infrared ray absorbing pigment to the camouflage print ink and paste.
- the fiber treated as such can provide only a low-level durability in terms of concealing performance against the near infrared detection.
- the organic pigments among near infrared ray absorbing pigments such as diimmonium, polymethine, metal complex, squarium type, and cyanine, mainly absorb the wavelength of 800 nm to 1,100 nm, but their near infrared ray absorption performance in the wavelength band equal to or greater than 1,100 nm is significantly reduced and their weatherproof performances of physicochemical characteristics may be significantly reduced because the pigments are seceded when repeatedly washed.
- the inorganic pigments such as cobalt, vanadium, molybdenum, tungsten, ITO, ATO, and ruthenium, effectively interrupt and absorb rays mainly in the wavelength equal to or greater than 1,200 nm, but the inorganic pigments are very expensive and also there is still a limitation in weather resistance due to the secession.
- the present invention provides a camouflage fabric with near infrared ray reflectance adjusting characteristics, which can significantly improve a poor durability occurring when a near infrared absorbing pigment and a carbon compound are coated on a synthetic fabric in a typical camouflage fabric manufacturing method, by weaving a camouflage fabric having a camouflage performance against a near infrared observation sensor using a conductive yarn containing copper sulfide nanoparticles or metal sulfide nanoparticles including copper sulfide.
- the present invention also provides a camouflage fabric with near infrared ray reflectance adjusting characteristics, which can achieve a certain camouflage effect by allowing a Near Infrared Ray Reflectance (NIRR) to be identical to or similar to those of natural backgrounds in a near infrared spectrum in which a near infrared ray wavelength band ranges about 720 nm to about 1,500 nm.
- NIRR Near Infrared Ray Reflectance
- the present invention also provides a camouflage fabric with near infrared ray reflectance adjusting characteristics, which can be used for military clothes, equipment, tents, and instruments by providing a camouflage fabric that has superior physiochemical properties and naturally exhibits antimicrobial properties and antistatic properties even without a separate post-treatment because metal sulfide nanoparticles including copper sulfide and copper sulfide nanoparticles have antimicrobial properties and conductive properties.

- the present invention can more effectively achieve a certain camouflage effect by allowing a Near Infrared Ray Reflectance (NIRR) to be identical to or similar to those of natural backgrounds in a near infrared spectrum in which a near infrared ray wavelength band ranges about 720 nm to about 1,500 nm.
- NIRR Near Infrared Ray Reflectance
