摘要： 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.

摘要： A plant-based functional polyester filament and a preparation method of the plant-based functional polyester filament are provided. The plant-based functional polyester filament includes polyester, and plant extract in a weight percentage range of approximately 0.1%-1.5%. The plant extract includes one or more of a peppermint extract, a valerian extract, a lavender extract, a wormwood extract, a chitin extract and a seaweed extract. The method includes preparing a plant-based functional polyester masterbatch, including: heating polyethylene terephthalate (PET) chips to a molten state, adding an antioxidant and a dispersant to the molten PET, stirring the molten PET, adding a protective agent and a plant extract to the molten PET, stirring the molten PET at a high speed, adding a modifier to the molten PET, obtaining a mixture by uniformly mixing the molten PET, and performing an extrusion granulation process on the mixture.
