Linen has been a significant material for textile packaging. Thus, the application of the simple spray-coating method to coat linen fibers with a flame-retardant, antimicrobial, hydrophobic, and anticounterfeiting luminescent nanocomposite is an innovative technique. In this new approach, the ecologically benign room-temperature vulcanizing (RTV) silicone rubber was employed to immobilize the environmentally friendly Exolit AP 422 (Ex) and lanthanide-doped strontium aluminum oxide (RESAO) nanoscale particles onto the linen fibrous surface. Both morphological properties and elemental compositions of RESAO and treated fabrics were examined by transmission electron microscopy (TEM), scanning electron microscopy (SEM), wavelength-dispersive X-ray fluorescence (WD-XRF), Fourier transform infrared (FTIR) spectroscopy, and energy-dispersive X-ray spectroscopy (EDX). In the fire resistance test, the treated linen fabrics produced a char layer, giving them the property of self-extinguishing. Furthermore, the coated linen samples' fire-retardant efficacy remained intact after 35 washing cycles. As the concentration of RESAO increased, so did the treated linen superhydrophobicity. Upon excitation at 366 nm, an emission band of 519 nm was generated from a colorless luminescent film deposited onto the linen surface. The coated linen displayed a luminescent activity by changing color from off-white beneath daylight to green beneath UV source, which was proved by CIE Lab parameters and photoluminescence spectral analysis. The photoluminescence effect was identified in the treated linen as reported by emission, excitation, and decay time spectral analysis. The comfort properties of coated linen fabrics were measured to assess their mechanical and comfort features. The treated linen exhibited excellent UV shielding and improved antimicrobial performance. The current simple strategy could be useful for large-scale production of multifunctional smart textiles such as packaging textiles.
亚麻一直是纺织包装的重要材料。因此，采用简单的喷涂方法用具有阻燃、抗菌、疏水和防伪发光性能的纳米复合材料包覆亚麻纤维是一项创新技术。在这种新方法中，采用生态友好的室温硫化（RTV）硅橡胶将环境友好型Exolit AP 422（Ex）和镧系掺杂的锶铝氧化物（RESAO）纳米颗粒固定在亚麻纤维表面。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、波长色散X射线荧光光谱（WD-XRF）、傅里叶变换红外（FTIR）光谱和能量色散X射线光谱（EDX）对RESAO和处理过的织物的形态特性和元素组成进行了研究。在耐火测试中，处理过的亚麻织物形成了一层炭层，使其具有自熄性能。此外，经过35次洗涤循环后，涂层亚麻样品的阻燃效果依然完好。随着RESAO浓度的增加，处理过的亚麻织物的超疏水性也随之增加。在366nm激发下，沉积在亚麻表面的无色发光薄膜产生了519nm的发射带。通过CIE Lab参数和光致发光光谱分析证明，涂层亚麻在日光下呈灰白色，在紫外光源下呈绿色，显示出发光活性。通过发射、激发和衰减时间光谱分析，在处理过的亚麻中发现了光致发光效应。对涂层亚麻织物的舒适性能进行了测量，以评估其机械性能和舒适特性。处理过的亚麻表现出优异的紫外线屏蔽性能和改善的抗菌性能。当前这种简单的策略可能有助于大规模生产多功能智能纺织品，如包装纺织品。
