Abstract

The invention belongs to the field of functional fiber materials, and discloses compound antiviral and antibacterial multifunctional PP, PE, PET non-woven fabric and preparation and application thereof. The preparation method comprises the steps that silica aerogel microspheres are used to load inorganic antiviral and antibacterial metal/oxides and antiviral and antibacterial components of traditional Chinese medicine correspondingly through a specific method, and then mixed with fiber slices and extruded to obtain master batch; and the master batch and the fiber slices are blended and spun and woven into shapes to obtain the compound antiviral and antibacterial multifunctional PP, PE, PET non-woven fabric. Through the adoption that the silica aerogel microspheres with a specific structureare used to load the inorganic and traditional Chinese medicine antiviral and antibacterial components correspondingly through the specific method, the components are added into fiber substrate, theobtained functional fiber material has long-lasting antiviral and antibacterial effects and is washable, the fiber strength and heat preservation effect are improved to a certain extent, and other health care functions of the fiber such as negative ions and far-infrared effects are not affected.

Description

technical field [0001] The invention belongs to the field of functional fiber materials, and in particular relates to a compound antiviral and antibacterial multifunctional PP, PE, PET non-woven fabric and its preparation and application. Background technique [0002] Due to the outbreak of the new coronavirus and the spread of infectious diseases caused by frequent viral infections, people's requirements for the protection of infectious viruses are becoming more and more urgent. Virus infection through the respiratory tract is mainly transmitted by virus-containing droplets (sneezing, etc.) discharged by the virus-infected person, so wearing a mask can slow down the spread of the virus to a certain extent. The demand for non-woven materials for preparing masks is increasing. In addition, some viral infections occur not only through direct contact with virus-containing droplets expelled by infected persons, but also through contact with clothes and towels that have been tou...
