Abstract

The invention relates to a modified ES fiber containing tea polyphenol, naringin or rheum emodin. The modified ES fiber comprises the tea polyphenol, naringin or rheum emodin, wherein the mass percentage of the tea polyphenol, naringin or rheum emodin is 0.1-5%. According to the modified ES fiber, the tea polyphenol, naringin or rheum emodin and a porous nanometer material are modified. Since theporous nanometer material has a large specific surface area, the tea polyphenol, naringin or rheum emodin is encapsulated in a pore channel of the porous material, so that the situation that components of the tea polyphenol, naringin or rheum emodin are damaged when the ES fiber is prepared in the later period is avoided, and the performance of the ES fiber is improved. By adding the tea polyphenol, naringin or rheum emodin, the antibacterial property, mechanical property and hygroscopic property of the ES fiber can be improved. According to the preparation of the ES fiber, by preparing functional master batches at first and then conducting blend spinning, the homogeneity of the ES fiber can be improved, and the performance of the ES fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to ES fibers modified by tea polyphenols, naringin or emodin and a preparation method thereof. Background technique [0002] ES fiber is a two-component (polypropylene PP / polyethylene PE) low-melting sheath-core hot-melt fiber. It is a new type of heat-bonding polyolefin fiber developed by Chisso Corporation in Japan in 1974. When the ES fiber is heated at a certain temperature, the PE on the surface melts and the PP on the core layer does not melt, forming a structure in which fibers are bonded to each other, and can be made into a non-woven fabric without adhesives. ES non-woven products are widely used in the manufacture of a series of disposable sanitary products such as sanitary napkins and diapers due to their fluffy, soft, high strength and excellent permeability. [0003] Tea polyphenols is the general term for polyphenols in tea, which is a white amorphous pow...
