Abstract

The invention discloses a preparation method for anti-infrared spectrum fabric. The preparation method comprises the following steps: performing fabric pretreatment, wherein the fabric is treated withalkaline, and is washed with water to be neutral; performing anti-infrared material preparation, wherein epoxy resin is heated and molten, a coupling agent is added for stirring reaction, and black silicon powder, aluminum foil powder and nano hollow microspheres are added and are uniformly stirred to obtain an anti-infrared material; spraying the prepared anti-infrared material onto the fabric,drying the sprayed fabric at a temperature of 110-130 DEG C, roasting the fabric for 3-8 minutes at a temperature of 180-200 DEG C, extruding the dried fabric, spraying the anti-infrared material to the extruded fabric, drying, and roasting in this way by 3-4 times, thereby obtaining the anti-infrared spectrum fabric; and dyeing the fabric. The anti-infrared spectrum fabric prepared by the preparation method has very good anti-infrared spectrum effect; and the anti-infrared spectrum material is embedded with the fabric, and the anti-infrared spectrum material can be combined with the fabric, so that the fabric is difficult to drop.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional fabrics, and in particular relates to a preparation method of infrared spectrum-resistant fabrics. Background technique [0002] Infrared (Infrared) is an electromagnetic wave with a frequency between microwaves and visible light, with a wavelength between 1mm and 760 nanometers (nm), and substances above absolute zero (-273.15°C) can produce infrared. [0003] Infrared detection is mainly carried out by using the difference in infrared radiation characteristics between the target and the background, that is, the difference in surface temperature and emissivity between the target and the background, and the distribution of these differences is the main factor determining the efficiency of infrared detection. Therefore, the purpose of infrared camouflage is to make the infrared radiation characteristics of the target consistent with the background through camouflage, that is, to r...
