Concentric filter stick suitable for heat-not-burn cigarettes and manufacturing process thereof

Abstract

The invention relates to a concentric filter stick suitable for heat-not-burn cigarettes. The concentric filter stick comprises a first acetate fiber section which comprises an inner-layer acetate fiber and an outer-layer acetate fiber which are concentrically arranged, wherein the inner-layer acetate fiber is a formed product obtained by mixing and dissolving one or more solvents of propylene glycol, glycerol, diethylene glycol, triethylene glycol, tetraethylene glycol, pentaethylene glycol, polyethylene glycol, sorbitol and xylitol with glyceryl triacetate and then adding the acetate fiber,and the outer-layer acetate fiber is a hardened acetate fiber filter stick. The preparation process comprises the following steps: 1) preparing mixed glyceride; 2) preparing a first acetate fiber section; 3) preparing the filter stick. According to the present invention, the mode of manufacturing the concentric filter stick is adopted, so the acetate fiber added with the smoke agent and the cooling material is placed on the inner layer of the concentric circle, the hardened acetate fiber filter stick is arranged on the outer layer, and the treated functional filter stick is used for the heating non-combustion cigarette, such that the smoke amount is significantly increased, the smoke temperature is significantly reduced, and the sensory comfort is significantly increased.

Description

technical field [0001] The invention belongs to the field of cigarette filter rods, in particular to a concentric filter rod suitable for heat-not-burn cigarettes and a manufacturing process thereof. Background technique [0002] In recent years, new tobacco products have achieved rapid development, and new products such as snus, chewing tobacco, electronic atomization cigarettes, and heat-not-burn tobacco products have widely appeared on the market, and the harm of these products has been significantly reduced compared with traditional cigarettes , so it has been recognized by the market and has occupied a certain market share in the international tobacco market. Among them, heat-not-burn tobacco products are the products closest to traditional cigarettes in terms of smoking quality and smoking habits, and their development prospects are good. The heat-not-burn tobacco technology uses smoldering carbon rods or heating electronic components to heat tobacco at a temperature ...

AI Technical Summary

Problems solved by technology

When ordinary cigarette filter rods are used, there are problems such as hot smoke and low smoke volume, which cannot meet the sensory requirements of heat-not-burn cigarettes
