Composite acetate fiber non-woven material applicable to cigarette filters and preparation method and application of composite acetate fiber non-woven material

Abstract

The invention relates to a composite acetate fiber non-woven material applicable to cigarette filters and a preparation method of the composite acetate fiber non-woven material. The composite acetatefiber non-woven material is prepared by mixing acetate fiber and other fibers, wherein the other fibers is one, two or three of polylactic acid fibers, metal fibers and carbon fibers. The composite acetate fiber non-woven material comprises 5-99wt% of cellulose acetate fibers and 1-95wt% of non-acetate-fiber material. The preparation method includes: opening the cellulose acetate fibers, mixing with the non-acetate-fiber material, carding, lapping, and performing spunlace to obtain the acetate fiber non-woven material. The acetate fiber non-woven material has a certain heat absorption effect and certain filtering performance and can lower smoke temperature and filter harmful components in smoke. After fiber mixing, the tensile strength of the non-woven material is enhanced, and the strength requirement of the cigarette filters produced by the non-woven material can be satisfied. The composite acetate fiber non-woven material can be used to produce incombustible cigarette filters.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and relates to a material in a cigarette filter rod and a preparation method thereof, in particular to a material capable of cooling and filtering mainstream smoke of non-burning cigarettes and a preparation method thereof. Background technique [0002] As the global tobacco control environment becomes increasingly severe and consumers pay more and more attention to health, the research and development of a new type of tobacco product that comprehensively and significantly reduces the release of harmful components of tobacco has gradually become the development focus of the tobacco industry in various countries around the world. Heat-not-burn cigarettes are new types of tobacco products that use a special heat source to heat the cut tobacco (below 500°C or even lower), and the cut tobacco is only heated without burning. Studies have shown that the release of harmful components in tobacco smoke...

AI Technical Summary

Problems solved by technology

However, so far, the market tests of the first two commercialized electric heating non-burning cigarette products (Accord, HeatBar) launched by Philip Morris Tobacco Company have not been successful, which further shows that electric heating non-burning cigarette products are still in the growth stage. In the early stage, there are still many problems, especially the core problem is that the smoking experience of electric heating non-burning cigarettes is poor, which is specifically reflected in the problems of high smoke temperature and poor smoke uniformity, which limits to a certain extent its marketing

At present, research on heat-not-burn cigarettes at home and abroad mainly focuses on cigarette device, cigarette design, cigarette paper, heating method and heater type, etc., but there is no relevant literature on the use of mixed non-woven materials for the cooling section of cigarettes and patent coverage
