A Method for Preparing PLA Tow Filter Rods with Low Draw Resistance for Reducing the Temperature of Smoke

摘要

A low-suction-resistance PLA tow filter rod for reducing the temperature of cigarette vapor and a preparation method therefor. The preparation method comprises steps of preparing a phase-change material mixture, preparing a phase-change material containing a flavor substance, preparing a slow-release flavor filter rod, etc. By increasing the addition amount of a phase-change material and performing combination with a low-suction-resistance PLA tow filter rod, by means of triple cooling, the overall suction taste of a cigarette and a heat-not-burn cigarette is improved and the temperature of cigarette vapor is also reduced, so that the suction comfort of a consumer is improved. The technological process is simple, and it is applicable to industrial production.
