Abstract

The invention relates to the technical field of textiles, in particular to a nano-functional finishing agent and a preparation method of the nano-functional finishing agent. The nano-functional finishing agent comprises the following components in parts by weight: 50 to 100 parts of nano TiO2 dispersion liquid, 10 to 20 parts of nanometer g-C3N4 particles, 20 to 40 parts of an emulsifier and 5 to10 parts of far-infrared ceramic powder. The nano-functional finishing agent disclosed by the invention is less in use amount, green and environmentally friendly and has the functions of antibacterialeffect, health and immunity improvement; the nano-functional finishing agent is ingenious in production process design, unique in feeding mode and uniformly mixed in a system, the stability of the finishing agent is enhanced, and the production efficiency is improved. The fabric having the finishing process by using the nano-functional finishing agent disclosed by the invention has excellent antibacterial properties, and is better in antibacterial property under ultraviolet irradiation.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a nano functional finishing agent and a preparation method thereof. Background technique [0002] With the significant improvement of people's living standards, more and more people pay attention to the quality of life. As textiles are important materials in daily life, people put forward more and higher requirements for textile products, which drives the processing of textile auxiliaries. The in-depth development of technology. Fabric finishing is to apply a finishing agent on the fabric, which can change the surface properties of the fabric, thus endowing the fabric with special functions. For example, hydrophobic and oil-repellent finishing is to treat the fabric with a finishing agent with low surface tension to change the surface characteristics of the fiber, so that the surface of the fabric is not easily wetted and spread by water or oil, so as to achieve the purpose of ...
