The spunbonded non-woven fabric containing the extract of the combined flower and the antipyretic can be widely applied to clothes contacted with skin, household textiles or medical protective products, including underwear, underpants, masks, socks, gloves, scarves, medical protective clothing, protective glasses and the like. Because the non-woven fabric contains the copperleaf inula herb pestilence-clearing extract, the clothes and medical protective products made of the non-woven fabric can slowly volatilize the traditional Chinese medicine components of the copperleaf inula herb pestilence-clearing extract, and the non-woven fabric is beneficial to improving the immunity of human bodies in life. The most obvious effect is that the mask is used in the mask. Some masks have replaceable inner cores, if the inner cores are made of non-woven fabrics containing the extract of the honeysuckle flower for clearing plague, people can inhale the component of the extract of the honeysuckle flower for clearing plague when breathing, and the mask has excellent effects of improving the capabilities of resisting inflammation, bacteria and virus for human bodies. Meanwhile, when people carry a common mask for a long time, water vapor is generated at the edges and faces of the mouth when people exchange and breathe, and the water vapor can cause bacteria to grow and other complications are caused. If the mask contains the honeysuckle antipyretic extract, the honeysuckle antipyretic extract can absorb more water vapor and avoid bacterial breeding while improving the anti-inflammatory, antibacterial and antiviral abilities.
