The present invention relates to a camouflage fabric having near infrared ray reflectance adjusting characteristics. The aim of the present invention is to achieve semi-permanent durability so as to significantly ameliorate problems of inferior durability which occur in an existing method for manufacturing a camouflage fabric, i.e. applying carbon and a pigment absorbing near infrared rays to a synthetic fabric, and to enable near infrared ray reflectance in a near infrared ray spectrum having an infrared ray wavelength band of 720 nm to 1500 nm so as to exhibit little or no difference from the near infrared ray reflectance of the natural background of each terrain, thereby achieving predetermined camouflage effects. In addition, copper sulfide nanoparticles, or metal sulfide nanoparticles containing copper sulfide, have antimicrobial properties and conductive properties, and the camouflage fabric for military use, which has superior physiochemical properties and naturally exhibits antimicrobial properties and antistatic properties even without a separate post-treatment, can be provided for effective use in clothing, equipment, tents, military supplies, etc. To achieve the above-described purposes, the camouflage fabric having the near infrared ray reflectance adjusting characteristics according to the present invention is characterized in that conductive synthetic polymeric materials in which copper sulfide nanoparticles, or metal sulfide nanoparticles containing copper sulfide, which fundamentally have near infrared ray reflectance adjusting characteristics, are coordinate bonded to a polymeric substrate and are then designed and woven such that the near infrared ray reflectance in a near infrared ray spectrum having the infrared ray wavelength band of 720 nm to 1500 nm exhibits little or no difference from the near infrared ray reflectance of an object existing in the environment.
A camouflage fabric with near infrared ray reflectance adjusting characteristics, comprising a conductive synthetic polymer material that is coordinate-bonded to polyamide reformed such that metal sulfide nanoparticles comprising copper sulfide or copper sulfide nanoparticles have a metal capturing functional group by a silane coupling agent containing imidazole and mercapto group, wherein contents of the conductive synthetic polymer material comprise about 0.1 wt % to about 3 wt % element copper and element additional metal with respect to a total weight thereof such that a near infrared ray reflectance of the conductive synthetic polymer material is equal or similar to near infrared ray reflectances of surrounding objects in a near infrared ray spectrum of about 720 nm to about 1,500 nm.
