Abstract

The invention relates to a hydrophilic polypropylene mixture which contains homopolymerization polypropylene and a hydrophilc agent. The hydrophilc agent is selected from one or more of alkyl polyoxyethylene ether, alkenyl polyoxyethylene ether, alkylphenol polyoxyethylene and alkyl amine polyoxyethylene ether. The invention further relates to a preparing method of the hydrophilic polypropylene mixture. The method includes mixing and contacting homopolymerization polypropylene with the hydrophilc agent. The invention further relates to the application of the hydrophilic polypropylene mixture prepared by the method and that of the hydrophilic polypropylene mixture in the preparation of melt blown non-woven fabrics. The provided hydrophilic polypropylene mixture has good hydrophilic properties with the hydrophilc agent contained, accordingly, the melt blown non-woven fabrics prepared by the hydrophilic polypropylene mixture have good hydrophilic properties.

Description

technical field [0001] The present invention relates to a hydrophilic polypropylene compound, a preparation method of the hydrophilic polypropylene compound, the hydrophilic polypropylene compound prepared by the method and the hydrophilic polypropylene compound in melt blown Applications in the preparation of textiles. Background technique [0002] Melt-blown non-woven fabrics are resistant to tensile deformation, and have high breaking strength and elongation at break. They are widely used in medical protection, clothing, home decoration, industrial fabrics, construction, civil engineering and agriculture. and other fields. [0003] Usually, the raw materials for the production of melt-blown non-woven fabrics mainly include homopolypropylene. The reason is that homopolypropylene is relatively cheap, has excellent rigidity, moisture resistance, heat resistance and good formability. [0004] However, due to the strong hydrophobicity of the polypropylene material, no matter...
