Abstract

The invention relates to a wormwood extract modified PP spunbond non-woven fabric. The modified PP spunbond non-woven fabric comprises the following effective components of, in percentage by mass, 0.1%-5% of wormwood extract. According to the preparation method, the wormwood extract and porous nano material are subjected to modification treatment, and the wormwood extract is "packaged" in porous channels of the porous material due to the fact that the nano porous material has a large specific surface area, so that components of the wormwood extract cannot be damaged when the non-woven fabric is prepared later, and the performance of the non-woven fabric is improved; soluble chitin, 2-hydroxybenzimidazole, cellulose acetate butyrate, adipic dihydrazide, N-hydroxysuccinimide and polyamine are added, so that the mechanical strength, the wear resistance and the moisture absorption of the non-woven fabric are further effectively improved; the obtained modified nano composite material is added into a fat-soluble solvent to be ground, can be dispersed uniformly, and is mixed and spun with PP slices to obtain the modified PP spunbond non-woven fabric, so that the softness, air permeabilityand water absorption of the non-woven fabric can be improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a PP spunbond nonwoven fabric modified by wormwood extract 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] Wormwood is a perennial herb. The leaves of wormwood are used as medicine. It is warm in nature, bitter in taste, non-toxic, pure in nature, clears the twelve meridians, restores yang, regulates qi an...
