Problems solved by technology

Patent CN101050602A provides a paper made of collagen fibers and its processing method, which can solve the problems of poor quality of paper made from plant fibers and damage to natural resources, as well as the high price of chemical fiber paper; at the same time, it can also solve the problem of skin or leather waste the reuse problem
However, in the above patents, either due to the use of chromium-containing leather waste, dechrome removal is required, resulting in complex production processes; or due to insufficient treatment, the collagen fiber bundles cannot be fully opened, and the fiber matrix cannot be completely removed, which affects the paper quality and quality. Performance
At the same time, there is no report on the use of paper containing collagen fibers for the preparation of cigarette filter rods

Abstract

The invention discloses a paper cigarette filter rod containing collagen fibers and a preparation method thereof. The paper cigarette filter rod comprises raw materials in the following weight proportions: 1-90% of collagen fibers and 10-99% of paper-making fibers. The preparation method comprises the following steps: preparing collagen fiber paper; adopting the conventional molding process of paper filter rods on the collagen fiber paper, rolling, rolling and wrapping the collagen fiber paper to obtain a paper cigarette filter rod containing collagen fiber. The paper filter rod prepared by the method can effectively reduce tar and other harmful components in cigarette smoke, and simultaneously improve the influence of ordinary paper filter rods on the smoking taste of cigarettes.

Description

technical field [0001] The invention relates to the technical field of cigarette filter rod preparation, in particular to a paper cigarette filter rod containing collagen fibers and a preparation method thereof. Background technique [0002] In the modern cigarette industry, cigarette filter sticks, as an indispensable part of cigarettes, undertake the important function of reducing tar and harm. At present, the filter element of the filter rod is mainly made of acetate fiber or polypropylene fiber. These fibers may enter the human body with the smoking of cigarettes and cause damage to human health. As people continue to pay attention to smoking and health issues, the emerging paper filter sticks cater to the development needs of the industry. Paper filter sticks have a good interception effect on flue gas, and at the same time, its raw materials are naturally renewable and low in cost, and paper filter sticks are more likely to be degraded. However, the paper filter rod...
