Study on the application of nano-magnesium hydroxide in flame retardant finishing of silk fabrics

Nano magnesium hydroxide, with its excellent flame retardant properties and environmental protection characteristics, has become an ideal choice for improving the flame retardant properties of natural fibers, especially silk fabrics. The following is a detailed analysis of the preparation of nano magnesium hydroxide and its application on silk fabrics:

Preparation Technology of Nano-Magnesium Hydroxide

Chemical precipitation method: By precisely controlling the reaction conditions, such as pH value, temperature, and stirring rate, the magnesium salt solution reacts with sodium hydroxide or ammonia water to generate magnesium hydroxide precipitation, thereby achieving the preparation of nanoscale particles. Surface modification: In order to enhance the dispersion and adhesion of nano-magnesium hydroxide on silk fabrics, surfactants or coupling agents are used for surface modification to give functional groups to the particles. Flame retardant finishing process of silk fabric

Finishing liquid preparation: Mix the nano magnesium hydroxide suspension with the additive to form a flame retardant finishing liquid. The additive helps the adsorption and fixation of nano particles on the fiber and improves the fabric performance. Finishing process implementation: Use padding, spraying or dipping-drying-heat treatment methods to evenly distribute the nano magnesium hydroxide on the silk fabric. Heat treatment promotes the combination of particles and fibers and enhances the flame retardant effect. The importance of performance evaluation

Flame retardant performance test: Evaluate the flame retardant performance of the finished fabric through LOI test, vertical burning test, residual carbon rate measurement, etc. Comprehensive performance considerations: Simultaneously evaluate color fastness, strength retention rate, etc. to ensure that the feel, gloss and mechanical properties of the finished fabric are maintained. The introduction of nano-magnesium hydroxide provides an efficient and environmentally friendly flame retardant solution for silk fabrics. After proper treatment, it can not only significantly improve the flame retardant properties of the fabric, but also maintain the soft feel and unique luster of silk, meeting the safety and quality standards of the high-end textile market.
