Problems solved by technology

[0014] The purpose of the present invention is to provide a hybrid filter for the current situation that the current single acetate tow filter cannot meet the needs of the tobacco industry; cannot meet the requirements of balanced adsorption and selective adsorption of harmful substances in smoke; various fibers with excellent functions cannot be used for filters. Fiber tow filter, based on acetate fiber tow, with degradable functional fiber filaments, by controlling the total denier ratio of acetate fiber tow and functional fiber filament tow, the filter rod molding effect Excellent, so that more types of functional fibers are expected to be used in filter rod processing, and the filtering effect of filter rods is improved

Abstract

The invention provides a composite filament strand filter tip for cigarettes. The filter tip is composed of mixed fiber filament strands which are formed by blending cellulose acetate filament strands and degradable functional fiber filament strands, wherein the total denier ratio of the cellulose acetate filament strands to that of the functional fiber filament strands is (5-3.1):1. Since the denier ratio of the cellulose acetate filament strands and the functional fiber filament strands is better, when glyceryl triacetate is used for forming, the filter tip is more excellent in usability and processability such as adhesion effect, hardness and draw resistance to meet the requirements of the cigarettes. Due to improvement of the functional fiber proportion, the filter tip is more effective in selective adsorption and balance adsorption of harmful substances and. Further, the technological base is provided for use of various functional fibers as filter tip materials.

Description

technical field [0001] The invention belongs to the technical field of tobacco materials, in particular to a composite tow filter rod for cigarettes. Background technique [0002] After incomplete combustion of cigarettes, more than 5,000 chemical substances can be produced, most of which are aroma components, and about 0.6% are harmful components, including 44 kinds of 13 types of harmful compounds in the gas phase of smoke and the condensed particle phase. The harmful substances in the gas phase are mainly carbon monoxide, nitrogen oxides, volatile aromatic hydrocarbons, hydrogen cyanide, volatile aldehydes and ketones, etc. The harmful substances in the particle phase are mainly fused ring aromatic hydrocarbons, N-nitrosamines, and phenols Substances, free radicals, heterocyclic compounds, heavy metals and radioactive substances, etc. Smoke tar is the main body of particulate matter, among which polycyclic aromatic hydrocarbons have carcinogenic effects, such as benzopyr...
