Abstract

The invention relates to tea polyphenol, naringin or rheum emodin modified PP spunbonded non-woven cloth. The tea polyphenol, naringin or rheum emodin modified PP spunbonded non-woven cloth is prepared from the tea polyphenol, the naringin or the rheum emodin, and the mass percent of the tea polyphenol, the naringin or the rheum emodin is 0.1-5%. According to the tea polyphenol, naringin or rheumemodin modified PP spunbonded non-woven cloth, the tea polyphenol, the naringin or the rheum emodin and porous nano-materials are subjected to modified process, the porous nano-materials have the large specific surface area, the tea polyphenol, the naringin or the rheum emodin is packed in a porous material hole channel, so that components of the tea polyphenol, the naringin or the rheum emodin are not damaged when the non-woven cloth is prepared later, and thus the performance of the non-woven cloth is improved. A fat soluble solvent is added into the modified nano composite materials for grinding and uniform dispersing, the modified nano composite materials are subjected to mixing and silk-spraying with PP slices, the modified PP spunbonded non-woven cloth is obtained, and the softness,air permeability and water-absorbing quality of the non-woven cloth can be improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a PP spun-bonded non-woven fabric modified by tea polyphenols, naringin or emodin and a preparation method thereof. Background technique [0002] PP spun-bonded non-woven fabric is a breathable rather than water-permeable fiber structure formed by using polypropylene raw materials, high-temperature spinning, carding, and bonding into a net. The non-woven fabric has moisture-proof, breathable, flexible, light weight, non-combustible, and easy to decompose. , non-toxic, non-irritating, rich in color, low in price, and recyclable. It is mainly used for disposable medical and sanitary products, disposable anti-fouling clothing, agricultural cloth, furniture cloth and as lining materials. [0003] Tea polyphenols is the general term for polyphenols in tea, which is a white amorphous powder that is easily soluble in water. The content of tea polyphenols in green tea is re...
