The necessity of camouflage in the visible region has been expanded to a broad region of the electromagnetic waves, especially infrared region, due to improving of the night vision cameras. In this investigation, the production of the poly(ethylene terephthalate) (PET) filament yarns with appropriate camouflage properties in both visible and infrared regions of forest areas in the melt spinning process was studied. C.I. Pigment Green 7 and C.I. Disperse Orange 149 with carbon black (CB) particles were used during the melt spinning to obtain the mentioned camouflage properties. The visible and near infrared wavelength reflectances, the mechanical and thermal properties, and the washing and light fastnesses of the camouflage PET filament yarn samples were evaluated. The results showed that the use of the optimum blend content of the mentioned dyes with CB particles during the melt spinning process could make desired camouflage properties in the PET drawn fibers. Moreover, acceptable mechanical and thermal properties accompanied with good to excellent washing and light fastnesses were observed for the optimized camouflage PET filament yarns. 相似文献

伪装是军事侦察的重要防护手段之一,然而,传统的迷彩图像生成方法不能实现端到端生成。本文采用循环一致性生成对抗(Cycle generative adversarial network, CycleGAN)算法实现迷彩图像生成,既保留原始图片的特征,又能实现端到端的生成。自行搜集并建立环境和迷彩图片库。利用CycleGAN算法的循环对抗博弈思想,训练生成和判别模型,在训练过程中,借助损失函数激励实现背景图像与迷彩图像的一一映射,将生成图像输入判别模型进行辨别,并将结果进行反馈。与DRIT、MUNIT模型生成的图像相比,CycleGAN算法生成的图像在色彩、纹理和边缘接近背景图像,呈现出良好的伪装效果,从而验证了实验方案的有效性,为服装智能图案设计生成提供了新思路。 相似文献
