Abstract

The invention provides a preparation method of a natural nano-functional finishing agent for silk. The natural nano-functional finishing agent for the silk is prepared from finishing agent liquid A, finishing agent liquid B, finishing agent liquid C and finishing agent liquid D, wherein the finishing agent liquid A is prepared from modified nano-particles, the finishing agent liquid B is preparedfrom a silane coupling agent, the finishing agent liquid C is mixed liquid of natural extracts and modified silicon emulsion, and the finishing agent liquid D is prepared from glutaraldehyde. During fabric finishing, the liquid B firstly reacts with the fabric, the liquid A is then used for treating, and the liquid D is cross-linked on the fabric by using the liquid C. Compared with the untreatedfabric, the fabric treated by using the finishing agent has higher ultraviolet resistance, softness, wrinkle resistance, antistatic property, yellowing resistance and antibacterial property; therefore, the finishing agent has an important application value in the aspect of silk fabric finishing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a silk natural nanometer functional finishing agent. Background technique [0002] Silk is soft to the touch, has good moisture absorption and air permeability, and is comfortable to wear. It is a kind of fabric that is favored by people. However, silk has the defects of easy wrinkling and shrinkage, which affects the wearing performance of silk. Therefore, people have been focusing on the research on the wrinkle resistance of silk for a long time. [0003] However, with the improvement of people's living standards, people's requirements for clothing are getting higher and higher, and multifunctional fabrics have become the trend of future development. The functions of traditional fabrics after finishing are relatively single, and most of the commonly used finishing agents are environmental pollutants, which have brought great harm to human l...
