Abstract

An on-line preparation device for antibacterial nonwoven fabrics for medical masks. When it is applied, the bottom spunbonded fiber web and the middle meltblown fiber web are laid on the upstream section of the conveying mesh curtain, and then the bottom spunbond fiber web and the middle meltblown fiber mesh are laid. When the fiber web moves to the laying section, the top spunbonded fiber web is laid from the drafting chamber to the top of the middle meltblown fiber web to obtain a three-layer composite fiber web, and then, when the three-layer composite fiber web moves to the downstream section, the top spunbond fiber web is The liquid spray port sprays negative water mist on the top of the three-layer composite fiber web to obtain antibacterial non-woven fabrics. The solute of the negative water mist is anionic polyelectrolyte; the fibers ejected from the spinneret move through the cooling chamber and the drawing chamber in turn. During the process to the laying section, the mixed spray port sprays mixed water mist into the drawing chamber, and the solute of the mixed water mist is cationic polyelectrolyte and nano titanium dioxide powder. This design is not only easy to produce, not limited by the surface structure modification process, but also has antibacterial and bactericidal functions at the same time.

Description

technical field [0001] The invention relates to a preparation technology of a nonwoven fabric for a medical mask, belongs to the technical field of functional nonwoven fabric preparation, and in particular relates to an on-line preparation device and a use method of an antibacterial nonwoven fabric for a medical mask. Background technique [0002] The main function of medical masks is to shield and block bacteria, droplets, external infections, etc., so as to effectively isolate external viruses or pollution. With the rapid development of modern industry, human beings have intensified the destruction of nature, and the pollution has become increasingly serious, leading to the reproduction and spread of various germs. Therefore, the requirements for the protective performance of the fabrics made of medical masks are also getting higher and higher. Performance is a very important indicator. Therefore, the development of antibacterial nonwovens is of great significance. SMS c...
