Abstract

A flame-retardant antibacterial phytic acid ammonium finishing agent for cellulose fiber and a finishing method of the flame-retardant antibacterial phytic acid ammonium finishing agent relate to finishing agents and a finishing process of the finishing agents, wherein the flame-retardant antibacterial phytic acid ammonium finishing agent is obtained via the reaction of phytic acid, urea and dicyandiamide. The preparation method of the flame-retardant antibacterial phytic acid ammonium finishing agent is that: firstly, a certain amount of the phytic acid, the urea and the dicyandiamide react fully in an oil bath condition to synthesize the flame-retardant antibacterial phytic acid ammonium finishing agent; and secondly, the flame-retardant antibacterial phytic acid ammonium finishing agent is dissolved in water so as to be prepared into finishing liquor with a certain concentration, and the cellulose fiber is finished by adopting a padding baking method. By the flame-retardant antibacterial phytic acid ammonium finishing agent, the cellulose fiber has flame retardance and an antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of finishing agents and finishing processes thereof, in particular to a flame-retardant and antibacterial ammonium phytate finishing agent for cellulose fibers and a finishing method thereof. Background technique [0002] Cellulose fibers (such as cotton, tencel, viscose, etc.) are favored by people because of their good moisture absorption and breathability, natural comfort, renewable and environmental protection, and are widely used in clothing, home textiles, decoration and other fields. However, cellulose fiber has a low ignition point and is a combustible fiber. When it is burned, it will continue to burn and smolder for a long time, producing a large amount of smoke, which is easy to cause a fire. At present, all walks of life have higher and higher requirements for flame retardancy of textiles. In order to endow cellulose fibers with excellent flame retardancy, the development of flame retardants is u...
