A kind of preparation method of dry-process grooved paper for filter stick

Abstract

A preparation method of dry-process grooved paper for filter rods, comprising: mechanically defibrating a fluff pulp board to obtain fluff pulp; one or all of hemp fiber, chemical synthetic fiber, cotton fiber, bamboo fiber, and vegetable protein fiber Some of the required treatments are fibers with a length of 2 to 10 mm; mix the processed fibers and fluff pulp evenly according to the weight ratio of 1:9 to 1:1; then air-laid, sprayed and consolidated, dried and shaped Get grooved paper. The grooved paper prepared by the invention has the characteristics of high bulkiness, good filling property and strong filtering effect, can effectively improve the adsorption of tar, NH3 and NNK in cigarette smoke, and can improve the smoking comfort of cigarettes.

Description

technical field [0001] The invention relates to the technical field of materials for cigarette filter rods and their preparation. Background technique [0002] As consumers pay more and more attention to health and safety issues, cigarette filters with functions of filtering and regulating smoke have become a hot spot in the industry under the background of tar reduction and harm reduction industry. The grooved filter tip can moderately reduce the tar content of cigarettes, so that the grooved filter rod is widely used. As the key material for making grooved filter rods, the grooved paper is increasingly developed for its tar reduction and harm reduction potential. [0003] At present, the industry generally believes that by changing the groove form of the filter rod, the ability of reducing coke and harm of the grooved filter rod can be improved to a certain extent. For example, a serial groove intercepting nozzle disclosed in Chinese patent CN 201774961 U, a staggered gro...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the current research on grooved paper for filter rods focuses on the structural design of grooves and the load and optimization of grooved paper. There is little research on the manufacturing process of grooved paper, and none of them can fundamentally solve the problem of grooved paper. Problems with grooved filter rods and grooved paper

Due to the limitations of the manufacturing process, the traditional grooved paper has many problems such as the grooves are easy to collapse and affect the appearance, the influence on the taste of cigarettes is great, and the smoke is dry, which limits the use of grooved filter rods.
