Abstract

The invention relates to an anion melt-blown superfine fiber cigarette filter material and a preparation method thereof. The anion melt-blown superfine fiber cigarette filter material is a melt-blown superfine fiber with the diameter ranging from 1 micrometer to 5 micrometers. The melt-blown superfine fiber is prepared from, by weight, 94-99 parts of a polypropylene chip and 1-6 parts of a nano-tourmaline master batch. The nano-tourmaline master batch is prepared by mixing nano-scale tourmaline powder and the polypropylene chip, and the content of tourmaline is 20%-40% of the mass of the nano-tourmaline master batch. The melt-blown superfine fiber is subjected to electret treatment. According to the anion melt-blown superfine fiber cigarette filter material, a conventional melt-blowing method is improved, traditional one-time fabric forming is changed into direct preparation of a superfine fiber bundle, and the fiber fineness is uniform; and the anion melt-blown superfine fiber cigarette filter material has the beneficial effects of being small in pressure drop, good in air permeability and capable of generating anion fresh air, the filtering effect on harmful substances in smoke is remarkably improved, and the problem of environment pollution in cellulose acetate fiber production can be avoided.

Description

technical field [0001] The invention relates to the field of cigarette filter material and the non-woven field, in particular to an anion melt-blown superfine fiber cigarette filter material and a preparation method thereof. Background technique [0002] Cigarette smoke contains particles, commonly known as tar. Tar contains a large number of chemical components, 4000 to 5000 kinds, all of which are products of incomplete combustion of tobacco. Cigarette filters are used to filter tar and other harmful substances in tobacco. Now the commonly used cigarette filter material is cellulose acetate cigarette filter, and cellulose acetate is made by wet spinning, the production process is long, and the solvent used in the spinning process is harmful to the environment and pollutes the three wastes. In addition, the effect of cellulose acetate fiber in filtering harmful carcinogens (such as polycyclic aromatic hydrocarbons and aldehydes) in mainstream cigarette smoke is not very s...
