Problems solved by technology

[0004] Phase change materials are more and more widely used in filter sticks and are mainly used to carry fragrance of fragrance substances. CN105595417 A discloses a linear composite gel fragrance slow-release filter rod and its preparation method and its use, which can effectively increase fragrance The amount of fragrance added to the wire filter rod, the uniformity, controllability and stability of the fragrance, there are few reports that it has the function of cooling, the phase change material itself is an endothermic reaction, and a large amount of heat needs to be absorbed during the process of changing from solid to liquid , which is also a physical cooling process

Abstract

The invention relates to a low draw-resistance PLA tow filter stick with reduced flue gas temperature and a preparation method thereof. The preparation method comprises the steps of preparing a phase-change material mixture, preparing a phase-change material containing fragrance substances, and preparing a slow-release fragrance filter rod. The present invention combines the addition of phase-change materials with low-drawing-resistance PLA tow filter rods, improves the overall smoking taste of cigarettes and heat-not-burn cigarettes through triple cooling, and at the same time reduces the temperature of smoke, which improves consumers' satisfaction. Suction comfort, simple process, suitable for industrial production.

Description

【Technical field】 [0001] The invention belongs to the technical field of cigarette product production. More specifically, the present invention relates to a method for preparing a polylactic acid tow filter rod with low draw resistance for reducing flue gas temperature. 【Background technique】 [0002] The smoke is released through the process of tobacco burning and distillation cracking. The smoke is filtered through a filter before being sucked into the consumer's mouth. The temperature of the smoke will be slightly lowered, but the temperature of the mainstream smoke reaching the mouth can still reach 35- 90°C. A high smoke temperature will cause smoke irritation and a burning sensation in the mouth, which reduces the comfort of smoking for consumers, especially at the back end of cigarette smoking. In order to control the temperature of cigarette smoke, developers and designers increase the length of the filter or apply ventilation technology, but these technologies wil...
