Abstract

The invention discloses a rare earth antibacterial and antiviral melt-blown fabric and a preparation method thereof, and belongs to the technical field of melt-blown fabric preparation. The melt-blown cloth prepared by selecting the rare earth oxide as the inorganic antibacterial and antiviral agent not only can maintain efficient antibacterial and antiviral effects for a long time, but also has anti-ultraviolet and anti-yellowing effects, and is non-toxic and non-irritant, and the safety is remarkably improved.

Description

technical field [0001] The invention relates to a rare earth antibacterial and antiviral meltblown cloth and a preparation method thereof, belonging to the technical field of meltblown cloth preparation. Background technique [0002] Melt-blown cloth has the advantages of ultra-fine fibers, many pores and small pore size, so it has good filterability, shielding and oil absorption, and is widely used in indoor air conditioner filtration, beverage filtration, water filtration and other filter materials. Medical and sanitary materials such as disposable masks and protective clothing, oil-absorbing environmental protection materials such as oil-absorbing cables, oil-absorbing chains, oil-absorbing pillows, and household wipes. General medical surgical masks are composed of melt-blown cloth and non-woven fabric, and the melt-blown cloth is mainly used to filter and retain bacteria and viruses. In order to ensure its filtering effect, electrostatic electret is usually required; w...
