Process for dip-coating fiber surface with emulsion polymerization chloroquine diphosphate microcapsules

Abstract

The invention belongs to the technical field of spinning, and particularly relates to a process for dip-coating fiber surface with emulsion polymerization chloroquine diphosphate microcapsules. The process comprises the steps that a fiber main material and hydroxypropyl methyl cellulose are added into a solvent, a stock solution is prepared by heating and dissolving, and then the stock solution isadded into a spinning box; the stock solution in the spinning box is ejected by a spinning jet, and is solidified in a DMAC aqueous solution to obtain a composite fiber; and the surface of the composite fiber is coated with the microcapsules with an antiviral agent containing chloroquine diphosphate as capsule cores and the fiber main material as capsule walls to obtain a finished fiber. According to the process, the antiviral agent containing chloroquine diphosphate is taken as the capsule cores of the microcapsules, then the surface of the composite fiber is coated with the microcapsules toobtain the finished fiber, so that in the use process, the antiviral agent on the surface of the finished fiber has a slow-release property, and the antiviral effective time of the finished fiber isprolonged.

Description

technical field [0001] The invention belongs to the technical field of spinning, in particular to a technique for dipping and coating the fiber surface with emulsion polymerized chloroquine phosphate microcapsules. Background technique [0002] Coronaviruses belong to the genus Coronavirus (Coronavirus) of the family Coronaviridae of the order Nidovirales in terms of systematic classification. The viruses of the genus Coronavirus are RNA viruses with an envelope (envelope) and a linear single-stranded positive strand in the genome, and are a large class of viruses that exist widely in nature. The diameter of coronavirus is about 80-120nm, the 5′ end of the genome has a methylated cap structure, and the 3′ end has a poly(A) tail. The total length of the genome is about 27-32kb. It is the virus with the largest genome among known RNA viruses . [0003] Coronaviruses only infect vertebrates, such as people, mice, pigs, cats, dogs, wolves, chickens, cattle, and poultry, and co...

Problems solved by technology

[0004] The applicant has also submitted a patent application for a method for making anti-coronavirus acrylic fiber with antiviral agents such as chloroquine phosphate added, but the applicant found in the follow-up experiment that there is still a technical solution in the previous application. The problem that needs to be improved is that the release rate of the antiviral agent is too fast, resulting in the problem that the antiviral effect of the fabric will decline rapidly in the early stage of use, so this application has carried out further research on this basis
