Abstract
The present invention discloses an algae modified pp spunbond non-woven fabric, which contains 0.1-2% of alginate. The algae modified pp spunbond non-woven fabric has a moisture regain of 0.2-3.5%, and an antibacterial rate ≥98%. The algae modified pp spunbond non-woven fabric prepared in the invention contains modified alginic acid, and also has hydrophilic functional groups, such as hydroxyl and amido groups, and hydrophobic functional groups such as branched alkyl groups. After spinning with pp into non-woven fabrics, protons can be both generated and received, so that when liquid is encountered on the surface of non-woven fabrics, the surface tension of liquid can be significantly reduced; additionally, there are a large number of gaps in the dense interpenetrating network structure formed by the modified alginic acid, which forms a structure like sponge having good hygroscopicity; moreover, the algae modified pp spunbond non-woven fabric absorbs water rapidly, the surface remains dry after absorbing water, and it can absorb many times its mass of water, so it has an excellent hydrophilicity.
