Method for preparing low-acetification natural fiber filter stick

Abstract

The invention discloses a method for preparing a low-acetification natural fiber filter stick, which comprises: selecting one or several of wood pulp fibers, cotton pulp fibers and jute pulp fibers; preparing a raw material for making low-acetification fibers by using tobacco cellulose diacetate vinegar sheet production equipment, washing and drying the raw material for making low-acetification fibers, and thus obtaining low-acetification finished fibers with a water content of 5 to 20 percent; making paper pulp by using 100 percent of low-acetification finished fibers, or mixing not less than 10 percent of low-acetification finished fibers with one or several of wood pulp fibers, cotton pulp fibers and jute pulp fibers to make paper pulp, making low-acetification fiber special paper, and making low-acetification natural fiber unitary filter stick by using the special paper; or mixing 100 percent of low-acetification finished fibers or not less than 10 percent of low-acetification finished fibers with one or several of wood pulp fibers, cotton pulp fibers and jute pulp fibers, spraying a glycerol triacetate plasticizer, coiling to make the low-acetification natural fiber unitary filter stick; or combining the unitary filter stick with an acetate fiber white stick to obtain a low-acetification natural fiber combined filter stick. The method can solve the moisture absorption deformation problem of the filter stick, effectively lower tar and the harmful ingredients of main smoke of cigarettes and improve the perceptual effect of the cigarettes.

Description

technical field

[0001] The invention belongs to the technical field of manufacturing cigarette filter rods, and in particular relates to a method for preparing cigarette filter rods by using low-esterified plant fibers as raw materials. Background technique

[0002] In cigarette filter rods, paper filter rods made of pure wood pulp fibers have good coke reduction effects, but their application in cigarettes has disadvantages such as moisture absorption and deformation of cigarette filter tips. Chinese patent application 200710098076.2 discloses "manufacturing technology of cellulose acetate paper" and Chinese patent 20081014346.2 discloses "a kind of paper for paper filter stick, filter stick and preparation method for reducing phenolic substances in cigarette smoke". Adding various types of cellulose diacetate to the paper and preparing a similar paper filter rod, trying to introduce cellulose acetate to improve the moisture absorption capacity of the paper and rely on the...
