Technical Field

The invention belongs to the technical field of functional fabric preparation, and particularly relates to a preparation method of an infrared spectrum preventing fabric.

Background

Infrared (Infrared) is an electromagnetic wave having a frequency between that of microwave and visible light, and can be generated by a substance having a wavelength of 1mm to 760 nanometers (nm) and a temperature higher than absolute zero (-273.15 ℃).

Infrared detection is mainly performed using differences in infrared radiation characteristics between an object and a background, i.e., differences in surface temperature and emissivity between the object and the background, and the distribution of these differences is a main factor determining the efficiency of infrared detection. Therefore, the infrared camouflage aims to enable the infrared radiation characteristics of the target to be consistent with the background through camouflage, namely, the infrared radiation difference between the target and the background is reduced or eliminated, the appearance of a camouflage object is damaged, and the purposes of camouflage and infrared detection avoidance are achieved. This can make it difficult for the infrared detection device to detect the target by improving the structural design and applying the infrared physical principle to attenuate and absorb the infrared radiation energy of the target.

For infrared clothing in the traditional sense, people usually adopt a method for changing the surface emissivity of a target to design and produce, namely, a textile material is subjected to certain weaving, dyeing and finishing processing and special product design to become a camouflage material with special performance.

At present, infrared preventive coatings applied to fabrics have been very hot, but some people still find their way to clothes fabrics, and such infrared preventive coatings are simply pressed on clothes fabrics and are liable to come off, resulting in loss of the infrared preventive function.
