Description

technical field [0001] The invention belongs to the field of fabric functional finishing methods, in particular to a preparation method of a Zn-MOF-based multifunctional dyed polyester fabric. Background technique [0002] Today, people's requirements for the functionality of textiles have undergone tremendous changes, and it is imminent to strengthen the development of functional textiles. Polyester is the largest and most widely used synthetic fiber in the world. Nowadays, people pay more and more attention to the development and research of new multifunctional dyed polyester fabrics. At present, the traditional functional finishing methods of polyester fabrics are either complicated, time-consuming and costly, or the effect is not good. In addition, traditional functional finishing methods often have a certain negative impact on the wearability of polyester fabrics, such as the mechanical properties, wear-resistant and washable properties, and softness and comfort of pol...
