Problems solved by technology

However, because polyethylene molecules contain a small amount of double bonds and ether bonds, sunlight and rain will cause aging.
[0003] Polyethylene is often used to make films, woven bags, non-woven packaging bags and other products. For some non-woven packaging bags for food, since food is easy to breed bacteria and mold during long-term storage, it is necessary to improve the quality of non-woven packaging. The antibacterial performance of the bag, and the anti-ultraviolet performance of polyethylene is not high, it needs to be improved to prolong its service life

Abstract

The invention discloses an antibacterial and anti-ultraviolet polyethylene non-woven fabric. An anti-fouling layer and an antibacterial and anti-ultraviolet layer are sequentially adhered to the surface of the polyethylene non-woven fabric, wherein the anti-fouling layer is made of dopamine and polyvinylpyrrolidone, and the antibacterial and anti-ultraviolet layer is made of modified silicon dioxide. The invention also discloses a preparation method of the antibacterial and anti-ultraviolet polyethylene non-woven fabric, which comprises the following steps of S1, soaking the polyethylene non-woven fabric in a mixed solution of dopamine and polyvinylpyrrolidone, washing, and drying to obtain an intermediate fabric; and S2, soaking the intermediate fabric in the modified silicon dioxide dispersion liquid, washing and drying to obtain the antibacterial anti-ultraviolet polyethylene non-woven fabric. The polyethylene non-woven fabric provided by the invention has good antibacterial and anti-ultraviolet properties. The polyethylene non-woven fabric provided by the invention has good antibacterial and anti-ultraviolet properties.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an antibacterial and anti-ultraviolet polyethylene non-woven fabric and a preparation method thereof. Background technique [0002] Polyethylene resin is a non-toxic, odorless white powder or granule, milky white in appearance, waxy in hand, and low in water absorption. Polyethylene is an alkane inert polymer with good chemical stability. However, because polyethylene molecules contain a small amount of double bonds and ether bonds, sunlight and rain will cause aging. [0003] Polyethylene is often used to make films, woven bags, non-woven packaging bags and other products. For some non-woven packaging bags for food, since food is easy to breed bacteria and mold during long-term storage, it is necessary to improve the quality of non-woven packaging. The antibacterial performance of the bag, and the anti-ultraviolet performance of polyethylene is not high, so it needs ...
