摘要
采用传统的染色方法,用天然染料紫草对蚕丝和纯棉织物进行染色实验,研究了染色后这些织物的迷彩伪装性能。实验发现,用紫草染色的天然纤维织物不仅有很好的紫外防护性能,而且对可见近红外迷彩伪装也有很好的防护,其防护指标能达到军队的防护标准。紫草迷彩伪装性能可能是它的主要成分α萘醌的共轭电子跃迁的结果。
Pure silk and cotton fabrics were dyed with natural dye lithospermum erythrorrhizon by the traditional method, and the camouflage properties of the dyed fabrics were evaluated. It is found by experiments that these fabrics have good camouflage protective functions in resistance to ultraviolet, visible, and near infrared rays. Their protective indexes are up to the standards of the army.These camouflage protective functions may be attributed to the electronic transition of a-naphthaquinone in lithospermum erythrorrhizon.
