Abstract

Woodland combat background (CB) is a common source of natural plant based natural dyes (NPND). Swietenia Macrophylla, Mangifera Indica, Terminalia Arjuna, Corchorus Capsularis, Camellia Sinensis, Azadirachta Indica, Acacia Acuminata, Areca Catechu and Cinnamomum Tamala were dried-grinded-powdered-extracted-polyaziridine encapsulated-dyed-coated-printed with leafy design on cotton fabric and tested against woodland CB under the reflection engineering of ultraviolet (UV)-visible (Vis)-near infrared (NIR) spectrums and photographic versus chromatic techniques of Vis imaging. The reflection properties of NPND treated and untreated cotton fabric were experimented by UV-Vis-NIR spectrophotometer from 220 to 1400 nm. Six segments of field trialling for NPND treated woodland camouflage textiles were also investigated for concealment, detection, recognition and identification of target signature against forest plants/herbs species; common tree of woodland CB such as Shorea Robusta Gaertn, Bamboo Vulgaris, Musa Acuminata; and a wooden bridge made by Eucalyptus Citriodora & Bamboo Vulgaris. The imaging properties such as CIE L*, a*, b* and RGB (red, green, blue) of NPND treated cotton-garments were captured by digital camera from 400 to 700 nm against tree stem/bark, dry leaves, green leaves and dry wood of woodland CB. Therefore, a colorful matching for concealment, detection, recognition and identification of target signature against woodland CB was verified by Vis camera imaging and UV-Vis-NIR reflection mechanism. UV-protection property of Swietenia Macrophylla treated cotton fabric was also investigated by diffuse reflection for defence clothing. Simultaneous 'camouflage textiles in UV-Vis-NIR' and 'UV-protective' property of Swietenia Macrophylla treated fabric have been investigated for NPND materials-based textiles coloration (dyeing-coating-printing) which is a new concept for camouflage formulation of NPND dyed-NPND mordanted-NPND coated-NPND printed textiles in terms of ecofriendly source of woodland camouflage materials. Therefore, technical properties of NPND materials and methodologies of camouflage textile assessment have been advanced in addition to coloration philosophy of natural dyed-coated-printed textiles.

摘要

林地作战背景（CB）是天然植物染料（NPND）的常见来源。将桃花心木、芒果、诃子、黄麻、茶树、印楝、相思树、槟榔和肉桂干燥、研磨、粉碎、提取、多氮嗪包封、染色、涂层、印花在棉织物上，并采用紫外线（UV）-可见（Vis）-近红外（NIR）光谱的反射工程和 Vis 成像的色度技术，在林地 CB 下进行测试。通过 UV-Vis-NIR 分光光度计从 220 到 1400nm 对 NPND 处理和未处理的棉织物的反射特性进行了实验。还对 NPND 处理的林地迷彩纺织品进行了六个野外试验段的试验，以研究对森林植物/草药物种、林地 CB 常见树种（如娑罗双属 Gaertn、竹类、芭蕉属）和由柠檬桉和竹类制成的木桥的目标特征的隐蔽、探测、识别和识别。通过数码相机从 400 到 700nm 捕获 NPND 处理的棉制服装的 CIE L*、a*、b*和 RGB（红、绿、蓝）成像特性，以应对林地 CB 的树干/树皮、干树叶、绿叶和干木。因此，通过 Vis 相机成像和 UV-Vis-NIR 反射机制验证了对林地 CB 的目标特征的隐蔽、探测、识别和识别的彩色匹配。还通过漫反射研究了处理过的桃花心木棉织物的紫外线防护性能，用于防护服装。同时研究了处理过的桃花心木织物的“UV-Vis-NIR 中的迷彩纺织品”和“紫外线防护”特性，以研究基于 NPND 材料的纺织品的染色（染色、涂层、印花），这是 NPND 染色-NPND 媒染-NPND 涂层-NPND 印花纺织品的迷彩配方的新概念，就林地迷彩材料的环保来源而言。因此，除了天然染色、涂层和印花纺织品的着色理念外，还推进了 NPND 材料的技术特性和迷彩纺织品评估方法。
