The invention discloses a printing process of a brocade-cotton blended camouflage fabric. The production process comprises the following steps: pretreatment, printing, steaming and baking, reduction soaping and color fixation, sizing, tentering and color fixation, preshrinking and the like. The camouflage printed fabric prepared by the process has the advantages of color fastness to light (dark color grade 6 or more and light color grade 5 or more), composite color fastness to light and sweat (grade 4-5), color fastness to dry rubbing (grade 4-5), color fastness to wet rubbing (grade 2.5-4), color fastness to washing (grade 4-5), color fastness to perspiration (grade 4-5) and color fastness to hot pressing (grade 4-5), excellent color fastness and uniform color fixation. Meanwhile, the produced camouflage fabric can control the reflectivity of light rays in a near-infrared light region (760-1200 nm) within a required range, so that the fabric has excellent infrared monitoring prevention performance and camouflage effect. The seven-color camouflage fabric printing is achieved, colors are richer, the camouflage effect is better, and the requirements of military garments are better met.

And the top of the bottom cover and the side face of the camouflage top cover are symmetrically provided with camouflage containing structures used for containing the camouflage control mechanism, and the problems that when a traditional vehicle is camouflaged every time, a large amount of time needs to be consumed for shell replacement, disassembly and assembly work, and installation operation is difficult are solved.

The invention provides a noise-based digital camouflage generation method, which comprises the following steps of: obtaining a scene color set by virtue of a color extraction algorithm through five environment images from different directions of a camouflage target, re-customizing and optimizing a genetic algorithm bottom layer operator aiming at a noise generation and superposition process parameter tuning problem, and obtaining a scene color set; on the basis of taking a newly-defined camouflage comprehensive evaluation factor as fitness, key parameters of a Perlin noise superposition texture generation process are adjusted and optimized, meanwhile, parameter adjustment and optimization ranges are limited for different types of camouflage objects, the optimal camouflage texture of a scene is generated after adjustment and optimization, then digital camouflage is generated in a digitized mode, and the optimal camouflage texture of the scene is obtained. And the final camouflage is obtained through further adjustment according to national standard specifications. The camouflage generation efficiency is greatly improved, and the self-adaptive camouflage effect of various camouflage objects in multiple scenes is improved.

This invention provides an electrochromic material, its preparation method, and its application. The structural formula of the electrochromic material is shown below: AR1 is a group represented by R1 or R3; AR2 is a group represented by R2 or R6; AR3 is selected from any one of R3, R4, and R5; AR4 is a group represented by R2; n is the degree of polymerization, and n is 4–35. This invention uses an arylation polycondensation process to prepare four high-performance solution-processable electrochromic materials: TTP, TEP, TPP, and PBP3P. Using these electrochromic materials as raw materials, high-performance patterned electrochromic camouflage devices are prepared using mask spraying. Nylon filter membranes with different pore sizes are introduced into the device structure to adjust the device's transmittance and achieve better camouflage effects.

The utility model relates to the technical field of camouflage nets, in particular to a camouflage net based on a spiral net, which comprises an outer fixing net belt, female bonding edge strips are arranged on four edges of the outer fixing net belt, side edge lug strips are connected to the left side and the right side of the outer fixing net belt in a front-and-back symmetry manner, through holes are formed in the side edge lug strips, and the through holes are communicated with the female bonding edge strips. A plurality of through holes are formed in the outer fixing mesh belt, fixing inserting cones are connected to the interiors of the through holes, a plurality of sets of inner fixing mesh belts which are arranged in order are arranged in the outer fixing mesh belt, spiral disguise bottom nets are connected to the interiors of the inner fixing mesh belts, and sub-sticking edge strips are sewn to the positions, located on the four edges, of the outer sides of the inner fixing mesh belts. A whole-piece spiral camouflage net is changed into a split-piece spiral camouflage net formed by bonding a plurality of groups of inner fixed net belts, so that the damaged spiral camouflage net can be quickly replaced, the whole spiral camouflage net does not need to be replaced, the cost is greatly saved, and meanwhile, the operation is convenient and trouble-saving.

The utility model discloses a rotating shaft module for firearms, which is convenient to mount and dismount. A rotating shaft module for firearms comprises a shaft sleeve, a shaft mortise and tenon and a rotating shaft, a stepped hole is formed in the shaft sleeve, the shaft mortise and tenon is in clearance fit with the large-diameter section of an inner hole of the shaft sleeve, a clamping shaft is arranged on the shaft mortise and tenon in the radial direction, an upper groove and a side groove are formed in the shaft sleeve and correspond to the clamping shaft, the upper groove is communicated with the side groove, the clamping shaft enters the upper groove, and the clamping shaft enters the side groove. The side face groove is used for being matched with the clamping shaft and limiting the axial limit position of the shaft clamping tenon, the rotating shaft is in clearance fit in the small-diameter section of an inner hole of the shaft sleeve, and a limiting head is arranged at one end of the rotating shaft, located in the large-diameter section of the inner hole of the shaft sleeve and limiting the axial position of the rotating shaft. The other end of the rotating shaft extends out of the shaft sleeve, and the end, extending out of the shaft sleeve, of the rotating shaft is used for being connected with a rotating component of a firearm.

The invention discloses a printing process of a polyester, vinylon and cotton blended camouflage fabric with a reverse anti-color-transmission function. The production process comprises the following steps: a pretreatment process, rolling of a waterproof agent on a single side of the reverse side, a printing process, baking and shaping, reduction and soaping, an after-finishing process and the like. According to the process, a waterproof agent is rolled on the reverse side of the fabric, so that the reverse side of the fabric has a water-repellent effect, color paste permeation is weakened, and reverse side permeation of dye in the subsequent printing process is prevented; the dyeing effect of the printing paste on the front side of the fabric is not influenced, and the permeation of the paste is effectively weakened, so that the printing effect that the front pattern is clear and the back is non-transparent is achieved; meanwhile, in the reduction soaping step, a waterproof agent on the reverse side of the fabric effectively maintains the printing effect, and the stability and quality of the printing effect are ensured. By adopting the disperse / vat dye one-paste printing process, the printed fabric is good in hand feeling and air permeability, five-color camouflage fabric printing is achieved, colors are rich, the camouflage effect is good, and the requirements of military garments are better met.
