Cigarette filter tip and manufacturing method thereof

Abstract

The invention relates to degradable materials, in particular to a cigarette filter tip which is made of natural materials such as plant-derived polysaccharides. A manufacturing method of the cigarette filter tip comprises the steps that raw materials are mixed to carry out fermentation, and extrusion forming is carried out through an extruding machine to form the cigarette filter tip. The cigarette filter tip comprises, by weight, 5-60 parts of polysaccharide, 20-60 parts of solvent, 0.5-10 parts of adsorbent, 1-30 parts of plasticizer, 0.1-10 parts of vegetable protein and 1-5 parts of zymophyte. When a cigarette filter tip made of traditional acetic acid cellosilk and the cigarette filter tip are compared, the amount of tar is reduced by 5% through the cigarette filter tip. Internal pores are uniform, the density is low, the capacity of intercepting the tar and toxic and harmful substances is good, and biodegradation can be rapidly carried out. According to the result of a soil burying test, the materials of the cigarette filter tip can be fully and biologically degraded in 28 days.

Description

[0001] The invention relates to a degradable material, more specifically to a cigarette filter prepared from natural source materials such as plant polysaccharides. Background technique [0002] Existing cigarette filter materials are mainly divided into two classes: one is acetate fiber; the other is polypropylene fiber. Acetate fiber is cellulose acetate, which is a man-made fiber obtained by the esterification reaction of plant cellulose and acetic acid. The filter tip made of it has good odor absorption effect, high efficiency of trapping mainstream smoke tar, and firm texture. Performance, suitable for use in middle and high-end cigarettes. However, in the production process of cellulose acetate, there are disadvantages such as three wastes pollution, high production cost, and difficulty in biodegradation after use. At present, my country's acetate fiber mainly relies on imports. The raw material of polypropylene fiber is cheap, but the spinnability is poor, and the ove...

AI Technical Summary

Problems solved by technology

The filling method is to add to other filter materials without substantial change; the spinning and rolling method is to spin the natural polysaccharide material first and then use acetate fiber filter forming processing method, the spinning preparation cost is high, and the processing technology system Complex, low yield

And the product use effect needs to be improved; the freeze-drying method requires a large investment in equipment, and the cold processing method has problems such as more pores and closed-cell structures, high energy consumption, and low production efficiency.
