Process for printing far infrared detection prevention camouflage fabric

Abstract

The invention relates to a process for printing a far infrared detection prevention camouflage fabric. The process is characterized by comprising the following processing steps of: (1) pretreatment, to be specific, baking and presetting a polyester filament oxford grey fabric, and preparing printing paste; (2) layout, to be specific, arranging a dye screen in front of a coating screen according to a process flow direction; (3) printing, to be specific, printing the printing paste on the pretreated grey fabric by using the dye screen and the coating screen; (4) ageing, to be specific, ageing the printed oxford fabric by using an ageing machine; and (5) washing, to be specific, washing the aged oxford fabric by using a washing machine, wherein washing liquor comprises 2 mass percent of soda, 0.5 to 0.8 mass percent of sodium dithionite, 1 mass percent of nonionic cleaning agent and the balance of water, and washing temperature is 60 to 70 DEG C. By adopting the unique printing process, the camouflage fabric capable of preventing the detection of a far infrared detection instrument can be obtained, and a person and an object covered by the camouflage fabric can be invisible in a complex battlefield environment, so that a good safe camouflage effect can be achieved.

Description

technical field [0001] The invention relates to a cloth printing and dyeing processing method, in particular to a printing process for anti-far-infrared detection camouflage cloth. Background technique [0002] On the battlefield, in order to ensure the safety of combatants and equipment teams, it is necessary to wear or wrap clothing or other materials with concealed effect to hide from daylight visual surveillance. These concealed clothing or other materials have been achieved by using certain colors of dyes to obtain camouflage colors to eliminate or weaken the visual difference with the surrounding environment. Therefore, for a long time, military uniforms and their camouflage materials are usually processed into green, olive, khaki, brown and black to adapt to the corresponding environment, especially the color of objects in the natural environment, such as trees, sand or soil, these camouflage materials The target that should be as close as possible to reduce the diff...

Problems solved by technology

With the development of infrared surveillance technology in World War II, the effect of such camouflage is gradually disappearing, because although these colors have a camouflage effect on visible light, they lose their camouflage effect when facing infrared rays
