Abstract: A disruptive camouflage pattern system to be used for both military and civilian applications. The system includes specialized techniques for printing the camouflage pattern system unto fabric. The system provides camouflage in both the human visible light and the near infrared range. The system depends on macro pattern resulting from a repeat of a micro pattern. The coloring used includes at least four colorings from dyes that in combination produce a percent reflectance value comparable to that of the negative space of the camouflaged subject's surroundings. The system functions by a macro pattern being disruptive of the subject's shape and a micro pattern having sharp edge units of a size capable of blending the subject into its background. The relative lightness values and percentages of total pattern, wet or dry, are sufficient to produce a percent reflectance of acceptable colors, in terms of lightness values unlike current four-color camouflage.

The ultra-fine inorganic fiber of the present invention has a very large specific surface area with respect to its volume. Thus it is very useful as catalyst supporting materials, reinforcing materials, coating materials or the like in every field of industry.
