Problems solved by technology

Acetate filter sticks have pure taste, remarkable coke reduction effect, and high production efficiency. However, the production capacity of cellulose acetate in my country is insufficient, and the key technology is owned by the United States. All raw materials rely on imports, and the price remains high.
Although the price of polypropylene fiber filter rod is relatively low, but the effect of reducing coke and the smell of smoke is poor, so it can only be used in a small amount on low-grade cigarettes
At the same time, acetate fiber and polypropylene fiber are extremely difficult to degrade in the natural environment, polluting the environment

Embodiment

[0021] The manufacture method of this viscose fiber cigarette filter rod comprises the following steps:

[0022] 1. First, use wood pulp, cotton pulp or bamboo pulp as raw materials to prepare viscose fiber filaments with a monofilament linear density of 1.5 to 8.0 dtex;

[0023] 2. Then the viscose filaments are coated on the surface of the viscose filaments with a concentration of 20% cellulose acetate solution (its solvent is acetone) through a dipping tank or a spray box with a concentration of 20% by weight. 10% of the weight of the fiber filament, and then dry off 70-80% of the solvent at 60-80°C, and bundle it into a tow with a linear density of 3.0-4.0ktex;

[0024] 3. The surface-coated viscose fiber tow is crimped by a crimper, and dried at 100-120°C to form a viscose fiber tow with a crimp number of 10-30 pieces / 25mm;

[0025] 4. Open the viscose fiber tow, spray triacetin, wrap the filter rod paper in the cigarette filter rod forming machine, cut into standard len...

Abstract

The invention provides a novel cigarette filter rod with high efficiency and low cost and a manufacturing method thereof for the technical field of tobacco. Its main feature is achieved by providing a new filter rod tow. The tow can use the main production equipment and process for preparing cigarette filter rods from cellulose acetate tow generally used at present. The tow is characterized by viscose fibers coated with a polymer coating and a suitable degree of crimp. Compared with cellulose acetate filter rods, viscose fiber filter rods can significantly reduce the tar content and improve the smoking quality. At the same time, the existing production equipment can be fully utilized, and the cost of cigarette manufacturing can be greatly reduced. It is a kind that can be produced in nature. Biodegradable, green and ecological new cigarette filter rod.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a viscose fiber filter rod with viscose fiber as the main component and a manufacturing method thereof. Background technique [0002] The tar in cigarette smoke is the main source of health hazards of tobacco, which has been confirmed by a large number of scientific studies. Tobacco harm has become one of the most serious public problems in the world today, and it is also one of the biggest problems facing human health. However, unlike other natural disasters, tobacco harm can be prevented and controlled. While the government is vigorously promoting the dangers of tobacco and calling on people to consciously resist the harm of tobacco, the tobacco industry has also carried out a lot of work to reduce the tar content of cigarettes, such as developing and planting low-tar tobacco leaves, reforming the preparation process of shredded tobacco and cigarette formula, and inserting filt...
