Abstract

The invention discloses a reaction type antibacterial agent as well as a synthetic method and an application thereof. The antibacterial agent is of a structure shown in a formula (I). The synthetic method comprises the following steps: dropwise adding a sodium sulfanilate solution into a cyanuric chloride or cyanuric fluoride solution, reacting for 1-4 hours at the temperature of 0-5 DEG C to obtain an intermediate product, adding a triclosan solution, reacting for 2-8 hours at the temperature of 30-60 DEG C to obtain a precursor of the reaction type antibacterial agent, chlorinating the precursor to obtain a finished product of the reaction type antibacterial agent. The application process comprises the following steps: soaking fabrics into finishing liquid formed by dissolving the precursor of the reaction type antibacterial agent and a metal salt catalyst in water, adding an alkaline agent, continuing the soaking treatment, chlorinating to obtain antibacterial fabrics. The antibacterial agent disclosed by the invention has the advantages of excellent bacteriostatic and sterilizing functions, high sterilization speed, high efficiency and simplicity in synthetic process; the application process has the advantages of short reaction time, low temperature, little damage on the fabrics and no toxicity or pollution, is simple to operate and meets the processing requirements of ecological textiles.

Description

technical field [0001] The invention belongs to the technical field of antibacterial agent synthesis, and in particular relates to a reactive antibacterial agent and its synthesis method and application. Background technique [0002] Textiles, especially cotton fabrics, which have the most contact with the human body, are prone to breed bacteria. This is because human secretions such as sugar, sweat, and sebum in cotton fibers provide essential nutrients for the growth and reproduction of some harmful microorganisms, and textiles The porous structure itself is also conducive to the attachment of microorganisms, which not only easily causes the spread of diseases, but also affects the performance of textiles to a certain extent. Therefore, it is of great significance to research and develop textiles with antibacterial function. The preparation method of antibacterial textile mainly includes adding antibacterial agent in the spinning process, antibacterial finishing and blend...
