Problems solved by technology

[0006] The above-mentioned antibacterial masterbatch uses silicate minerals as the carrier of metal ions, so as to prevent metal ions from being reduced and discolored, entrap metal ions, and prevent metal ions from coming out to cause environmental pollution; but the preparation method of the above-mentioned functional powder is relatively complicated. , so that the production cost of antibacterial masterbatch is high, and energy consumption is increased; whether it is a single use of metal ion antibacterial agent or the use of carrier metal ions to form an antibacterial agent, a large amount of metal ions will be involved in the preparation process, which will cause a burden on environmental protection

Abstract

The invention discloses an antibacterial spinning mixture as well as a preparation method and application thereof. The antibacterial spinning mixture comprises carrier resin slices and a composite antibacterial agent which are blended, wherein the composite antibacterial agent comprises an antibacterial agent and a carrier used by the antibacterial agent, and the antibacterial agent is at least one of 4,5-dichloro-N-octyl-4-isothiazolin-3-one, methylchloroisothiazolinone and methyl isothiazolinone. According to the antibacterial spinning mixture, at least one of the 4,5-dichloro-N-octyl-4-isothiazolin-3-one, the methylchloroisothiazolinone and the methyl isothiazolinone serves as the antibacterial agent, and the DCOIT, the CMIT and the MIT can kill bacteria and fungi in a broad-spectrum and efficient mode, are extremely high in water resistance and weather resistance, do not contain heavy metals, can rapidly permeate into precipitates to be decomposed after being released, and are very environment-friendly; and after being used in cooperation with the used carrier, the antibacterial agent has a good slow-release effect, so that the bacteria can be resisted for a long time.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, in particular to an antibacterial spinning mixture and its preparation method and application. Background technique [0002] With the continuous improvement of people's requirements for the quality of life, people pay more and more attention to the hygiene management of the living environment. Therefore, many clothing, food packaging and hygiene products are currently made of antibacterial fibers. However, the current antibacterial fibers are usually obtained by impregnating the fibers with antibacterial agents or coating the surface of the fibers. Such antibacterial fibers are not water-resistant and have poor durability, resulting in poor antibacterial and antibacterial effects. [0003] In order to solve the above problems, the Chinese invention patent application with the publication number CN107141731A discloses an antibacterial masterbatch and a preparation method thereof. The antiba...
