Embodiment 1

[0013] In the present embodiment, the specific steps of the flame-retardant antibacterial ammonium phytate finishing agent and the finishing method thereof for cellulose fiber are as follows:

[0014] (1) Weigh 86.4 grams of phytic acid aqueous solution with a mass fraction of 50%, 42 grams of urea, and 25.2 grams of dicyandiamide, mix them into a 0.25-liter reactor, stir and heat up to 100 °C under the condition of an oil bath , reacted for 3 hours to obtain a flame retardant and antibacterial ammonium phytate finishing agent;

[0015] (2) The flame-retardant and antibacterial ammonium phytate finishing agent was mixed with water to make a finishing solution with a concentration of 20%, and the cellulose fiber was added to the finishing solution at a bath ratio (that is, the ratio of the finishing solution to the weight of the fabric) of 10:1. Dipping at 50°C for 20 minutes, soaking in water, drying, and then baking at 170°C for 5 minutes to complete the finishing process. A...

Abstract

A flame-retardant and antibacterial ammonium phytate finishing agent for cellulose fibers and a finishing method thereof, relating to the technical field of finishing agents and finishing techniques thereof, wherein the flame-retardant and antibacterial ammonium phytate finishing agent is prepared by reacting phytic acid, urea and dicyandiamide have to. Its preparation method is as follows: first, a certain amount of phytic acid, urea and dicyandiamide are fully reacted in an oil bath to synthesize a flame-retardant and antibacterial ammonium phytate finishing agent; secondly, the flame-retardant and antibacterial ammonium phytate finishing agent is dissolved in water to prepare Prepare a finishing solution with a certain concentration, and use the method of padding and baking to finish the cellulose fiber. The invention makes the cellulose fiber have flame retardancy and 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...
