Anti-infrared military camouflage fabric and printing and dyeing process thereof

Abstract

The invention discloses anti-infrared military camouflage fabric and a printing and dyeing process thereof. Warp and weft yarns of the camouflage fabric use cotton polyester blended yarns; the cotton polyester blended yarns are formed by blending 40 to 60 weight percent of cotton fiber, 30 to 50 weight percent of polyester fiber, 5 to 10 weight percent of polyamide fiber and 5 to 10 weight percent of spun silk fiber. The printing and dyeing process of the anti-infrared military camouflage fabric comprises the following steps of S1, a pretreatment process; S2, a dyeing process; S3, a printing process; S4, tentering sorting, wherein the dyeing process uses disperse bath process dyeing of reduced dye and disperse dye; the printing process uses printing of reduced dye and disperse dye in one paste. According to the anti-infrared military camouflage fabric and the printing and dyeing process of the anti-infrared military camouflage fabric, the fabric obtained through the printing and dyeing process has the advantages of good anti-infrared camouflage performance, high color fastness of all items, full color and luster and low cost.

Description

technical field [0001] The invention relates to the technical field of fabric printing and dyeing, in particular to an anti-infrared military camouflage fabric and a printing and dyeing process thereof. Background technique [0002] With the improvement of the threat of infrared reconnaissance, various means of preventing infrared reconnaissance are becoming more and more important. The United States, Britain, Japan and other countries have all started research on anti-infrared reconnaissance methods, among which the research on anti-infrared reconnaissance camouflage materials is the most important. The research on anti-infrared materials has a history of nearly half a century, while the domestic research on infrared camouflage materials began in the 1980s. For textile fabrics as camouflage materials, it is relatively easy to achieve camouflage through coatings in previous studies, which generally contain SnO 2 , Fe 3 o 3 , ZnO and other metal oxide coatings are coated ...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this method is that a large number of coatings will cause excessive absorption of thermal infrared bands, increase the reflection of radar waves, visible light and laser light, which is not conducive to the stealth of these detectors, and the coated fabric is hygroscopic and breathable. In addition, due to the performance limitation of the pigment itself, it is difficult to prepare a camouflage color that is completely close to the background. Generally, there is a permissible deviation of the camouflage color within a specified limit.

[0003] At present, some scholars use dyes instead of paints to form popular stealth materials, which just overcomes the shortcomings of the above-mentioned aspects. However, more information about dyes instead of paints to form thermal stealth materials is rarely reported. On the one hand, it is about the synthesis and structure of dyes. And the composition and application are all carried out in secret, on the other hand, in order to achieve satisfactory results and be suitable for military use, further technical research is still needed
