Abstract

The invention discloses a preparation method of a UV resistant nonwoven cloth for a surgery hole drape. The preparation method comprises following steps: step one, mixing TiO2:(Al, Ce) powder, N,N-dimethyl acetamide, and zirconium beads, and grinding the mixture to prepare TiO2:(Al, Ce) dispersion liquid; step two, mixing polyamide and N,N-dimethyl acetamide, stirring, adding the TiO2:(Al, Ce) dispersion liquid, maintaining the temperature, and keeping on stirring to obtain a spinning solution; and step three, using the spinning solution to carry out electrostatic spinning to obtain TiO2:(Al,Ce) / polyamide nonwoven cloth, namely the UV resistant nonwoven cloth for a surgery hole drape. The prepared nonwoven cloth has a very good antibacterial and UV resistant performance.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a method for preparing an antibacterial and anti-ultraviolet non-woven fabric for surgical drapes. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing. Therefore, non-woven fabrics are widely used in medical protection, clothing, in the fields of industry and agriculture. However, the current medical non-woven fabrics cannot meet the various needs of medical use in terms of antibacterial and anti-radiation, and their functions are relatively single. Contents of the invention [0003] Based on the technical problems ...
