Popular Science | Fibers in the Cigarette Holder

According to incomplete statistics, there are more than 300 million smokers in China. With the improvement of national health awareness, more and more smokers have begun to pay attention to the harm of smoking to health and find ways to reduce the harm. Filter mouthpieces, as a common tool to reduce the harm of smoking, have been favored by the majority of smokers. Today, let's talk about mouthpieces with friends. Cigarette mouthpieces are commonly known as filter mouthpieces. It is a small filter rod located at the mouth of the cigarette. As early as the 1920s, some tobacco companies invented such a filter rod in order to reduce the discomfort of the tobacco leaves directly contacting the lips. At the same time, it can filter out some tar and smoke, which seems to be healthier. However, according to research by Chinese researchers, rush fiber has a natural advantage in this regard! So what is rush fiber and how is it used in the filter mouthpiece? Today, the editor will give you a popular science: rush is a perennial herb belonging to the genus Juncus of the Juncaceae family. It is mainly distributed in Hebei, Shaanxi, Gansu, Shandong, Jiangsu, Zhejiang, Jiangxi, Hubei, Yunnan, Tibet and other places in China. Rush fiber is a typical cellulose fiber, a macromolecular polysaccharide composed of glucose, and has the physical and chemical properties of cellulose fiber. Rush fiber has a rough surface structure and a three-dimensional structure composed of a hierarchical multi-layer mesh structure inside. The chemical composition of rush is mainly cellulose, hemicellulose, and lignin. Its macromolecules contain a large number of hydroxyl groups, which is conducive to the functionalization and application of rush. Rush fiber also has good thermal stability. The Xu Weilin team of Wuhan Textile University has developed a rush harmful gas filtration device, modified the rush fiber, and made the modified rush fiber into a filter cigarette holder to reduce the content of harmful substances in mainstream smoke. In addition, in the process of treating dye wastewater, natural cellulose rush fiber with a three-dimensional mesh porous structure can effectively reduce the secondary pollution caused by traditional inorganic metal semiconductors. Rush is also a medicinal plant with the effects of clearing heat, promoting water and moisture, and can be used for gonorrhea, edema, insomnia, throat paralysis, trauma and other diseases. In general, rush is a plant with multiple uses and values, and has a wide range of applications in textiles, ecology and medicine.
