Problems solved by technology

The disadvantages of this solution: in the adsorption of harmful substances in smoke by cigarette filters, the adsorption effect on carbon monoxide, benzo(a)pyrene, phenol, and crotonaldehyde is not good; the ability to absorb tar is poor, and the taste of smoking is not good
The disadvantages of this solution: in the adsorption of harmful substances in smoke by cigarette filters, the adsorption effect on hydrogen cyanide, benzo(a)pyrene, phenol, and crotonaldehyde is not good; the filter has high suction resistance and poor smoking experience
The disadvantages of this scheme: the polylactic acid fiber filter rod has limited adsorption capacity for harmful components in flue gas, and the ability to absorb tar needs to be improved; after the filter rod is deformed under pressure, its rebound performance is not good, it is easy to deform and collapse, and the ventilation rate is high. Affects the pumping experience
[0010] (1) In order to maintain a suitable range of draw resistance in the existing polylactic acid tow cigarette filter, its adsorption effect on harmful substances in cigarette smoke is not ideal, and the adsorption effect is lower than that of the traditional cellulose acetate filter. The oral cavity of the human body is highly irritating; however, if the adsorption effect of the filter tip is improved, the suction resistance of the filter tip will increase, which will cause the problem of difficult suction and unpalatable taste; Phenomenon of Negative Correlation
[0011] (2) The deformation resilience of existing polylactic acid tow cigarette filter is not good, and the filter is easy to be crushed and deformed during processing and smoking, resulting in a decrease in the adsorption effect of the filter on harmful substances and a significant increase in suction resistance The problem
[0012] (3) The ventilation rate and hardness of existing polylactic acid tow cigarette filters are not as good as those of traditional filters. The high ventilation rate and poor hardness affect the smoking experience

Description

technical field [0001] The invention relates to the field of polylactic acid, in particular to a polylactic acid tobacco tow, a preparation method and an application thereof. Background technique [0002] At present, China is the world's largest tobacco producer and consumer. The number of smokers in China accounts for nearly 30% of the total number of smokers in the world, ranking first. Tobacco contains a variety of biological nicotine, nornicotine, anatabine, and anatabine. Tobacco smoldering produces tributary smoke, and the concentration of aerosol particles in the smoke is 10,000 times higher than the concentration of pollution on the highway , high concentration, great harm. The number of deaths caused by smoking in my country exceeds 1 million every year, and at the same time, about 100,000 people die from second-hand smoke in my country every year. Our public’s awareness of the hazards of smoking and second-hand smoke exposure is seriously insufficient. The smoke ...
