Desert type anti-infrared camouflage fabric printing technology

Abstract

The invention discloses a desert type anti-infrared camouflage fabric printing technology. The technological process comprises steps as follows: printing, baking, padding by a reduction liquid, rapid vat ageing, oxidizing, soaping, hot water washing, washing and drying. A high-temperature type disperse dye with good sublimation fastness and small cotton fiber staining and an anthraquinone indanthrene dye are adopted to perform one-paste printing with a double-phase method, a technology of thermosol and later reduction is adopted after drying, so that the color yield is increased, mutual staining is reduced, and dark and gloomy color and luster are avoided; the light transmittance of terylene is 100%, that is, the light reflectivity is zero, so that the colored light requirements are met by adjusting the use quantity of the disperse dye when the colored light approaches.

Description

[0001] technical field

[0002] The invention belongs to camouflage fabric printing, in particular to a desert type anti-infrared camouflage fabric printing.

[0003] Background technique

[0004] Anti-infrared camouflage printing is mostly used in military camouflage clothing and tents. For textile fabrics, it is relatively easy to achieve camouflage through paint. Generally will contain SnO 2 , Fe 2 o 3 , ZnO and other metal oxide coatings are coated on the surface of the fabric to reduce the reflectivity of the fabric to infrared rays. But the disadvantage of this method is that a large amount of paint will lead to excessive absorption of thermal infrared bands, increasing the reflection of radar waves, visible light and laser light, which is not conducive to the stealth of these detectors. There is also the problem of metamerism in the printing process. Brown, green and gray in the color spectrum are very important color systems for camouflage pigment printing met...
