Study on preparation and performance of multifunctional linen fabric finishing agent

The research in textiles is being driven by economy and functionality. Therefore, the present research is focused on the development of multifunctional textiles with simple process. Herein, a highly efficient multifunctional linen fabric finishing agent was developed with nano-ZnO, dodecafluoroheptyl methacrylate, vinyl trimethoxysilane, methyl methacrylate, and butyl acrylate as raw materials. The finishing agent imparted linen fabric multiple performance characteristics such as hydrophobic, antibacterial and ultraviolet protection. Infrared spectroscopy analysis, particle size test and transmission electron microscopy were used to analyze the main characteristics of multifunctional linen fabric finishing agent, including the main groups, particle size distribution and particle morphology. The results showed that the nano-ZnO/fluorosilicone-polyacrylate emulsion finishing agent had been successfully prepared, and the finishing agent had good stability. By means of scanning electron microscopy, thermogravimetry, and X-ray diffractometry, it was found that the finishing agent successfully covered the surface of the linen fabric, which increased the thermal decomposition temperature of the linen fabric and reduced the crystallinity of the linen fabric, indicating that improved the heat stability and softness of the fabric. Similarly, the application performance of linen fabric was tested. Compared with the original linen fabric, the finished linen fabric had good ultraviolet protection, antibacterial, hydrophobicity, washing fastness and breaking strength, leading to the improvement of the wear performance of linen fabric. Thus, the multifunctional linen fabric finishing agent has the advantages of simple technology, low cost and promising prospect.
