Abstract

The control possibility assessment of the water-repellent properties of polyester (PEF) fabric when its hydrophobizing with tetrafluoroethylene (TFE) telomers due to texturing by applying nanosized SiO2 is discussed. It was established that the use of a compound containing SiO2 nanoparticles and TFE telomers for hydrophobization of PEF fabrics led to an increase in roughness of the coatings, however, a decrease in contact angles of fabric and an increase in its water absorption were observed. This is due to an additional increase in hardness of the coating based on TFE telomers, when combined with SiO2 nanoparticles.

聚四氟乙烯端聚物和二氧化硅纳米颗粒沉积聚酯织物涂层的疏水性控制

讨论了应用纳米SiO2织构对涤纶(PEF)织物与四氟乙烯(TFE)调聚物疏水的控制可能性评价。结果表明，使用含有SiO2纳米颗粒和TFE端粒的化合物对PEF织物进行疏水性处理，使涂层的粗糙度增加，但织物的接触角减小，吸水率增加。这是由于当与SiO2纳米颗粒结合时，基于TFE端粒的涂层的硬度额外增加。
