标记包括在产品上添加标记以进行识别。研究了甲基丙烯酰胺（MAam）和2-羟乙基甲基丙烯酸酯（HEMA）作为纤维素纱（亚麻）的标记物。利用化学引发技术的氧化还原体系，将反应性单体接枝到纤维素链上。用傅里叶红外光谱（FT-IR）对产物进行表征。选择HEMA是因为它的特征波段更明显。研究了影响HEMA聚合的主要因素，包括浓度、反应时间和温度，确定了最佳接枝条件。我们注意到接枝不影响纱线的机械性能。
Marking consists of adding a mark on a product for the purpose of its identification. The use of methacrylamide (MAam) and 2-hydroxyethylmetacrylate (HEMA) as markers for cellulose yarn (flax) has been studied. Grafting of a reactive monomer onto cellulose chains has been carried out using a redox system with a chemical initiation technique. The products were characterized by Fourier transform infrared (FT-IR) spectroscopy. HEMA has been chosen due to its more pronounced characteristic band. The major factors affecting HEMA polymerization, including concentration, reaction time and temperature, were studied to establish the optimum grafting conditions. We note that the grafting does not affect the mechanical properties of the yarn.
