摘要

在操作由易燃纺织品制成的易搭建的建筑物时,应采取防火措施,因为操作时可能会引燃油布,而油布是一种易燃材料。因此,旨在确定以有机和无机物混合物为基础的织物上阻燃涂层弹性层形成模式的研究具有必要的技术特性。本文介绍了防水布的自由表面能及其组分(极性和分散性)的研究结果,以及使用阻燃涂层时其变化的方法。在测试过程中,用移液管将一滴涂层涂在样品上。达到平衡滴后,用显微镜测定其高度和直径。阻燃涂层形成后极性变化的顺序及其与织物主要成分的关系,与篷布织物的结构和功能特征相一致。所得织物的特点是吸水性能降低,因为自由表面能变化2.3倍,极性变化2倍,这与涂层表面张力的降低有关。综上所述,发现帆布织物的极性与阻燃涂料的极性接近,难以润湿材料。相反,添加发泡剂减少了涂层的极性,增加了润湿性,这使您可以有效地处理帆布织物。因此,在应用综合方法研究润湿性、极性、界面张力时,您可以为阻燃织物的新产品选择稳定的技术并扩大其范围。

RESEARCH OF SURFACE PROPERTIES OF FABRICS FOR MANUFACTURE OF TENTS
The operation of easily erected structures made of flammable textiles encourages the use of fire protection, as the operation may ignite tarpaulin fabric, which is a flammable material. Therefore, studies aimed at determining the patterns of formation of an elastic layer of fire-retardant coating on fabrics with a composition based on mixtures of organic and inorganic substances, characterized by the necessary technological properties, are relevant. The paper presents the results of studies of free surface energy, as well as its components (polar and dispersed) for tarpaulin fabric and methods of its change when using a fire-retardant coating. A drop of coating was applied to the sample with a pipette during the test. After reaching the equilibrium drops, its height and diameter were determined with a microscope. The sequences of polarity change and their relationship with the main component of the fabric after the formation of the flame retardant coating, which are consistent with the structural and functional features of the tarpaulin fabric. The resulting fabric is characterized by a reduced property of water absorption, as the free surface energy changes 2.3 times and the polarity 2 times, which is associated with a decrease in the surface tension of the coating. Given the above, it was found that the polarity of the canvas fabric is close to the polarity of the flame retardant coating, which is difficult to wet the material. Instead, the addition of a foaming agent reduces the polarity of the coating and increases the wettability, which allows you to effectively process the canvas fabric. Thus, when applying a comprehensive approach to the study of wettability, polarity, interfacial tension, you can choose stable technologies for new products from fire-retardant fabric and expand their scope.
