Abstract

The invention belongs to the technical field of filter materials, and specifically relates to a filter material with the function of removing tobacco smell. The filter material with the function of removing tobacco smell comprises the following layers which are sequentially stacked: a nonwoven fabric layer, a meltblown fabric layer, an activated carbon cloth layer and a base material layer; the activated carbon cloth layer contains an activated carbon composition; and the activated carbon composition comprises 20-40% of acidic-gas-removed coconut shell charcoal, 15-25% of alkaline-gas-removedcoconut shell charcoal and 40-60% of activated carbon of which the CTC content is higher than 70%. Compared with the prior art, by adding the activated carbon compositions, the filter material with the function of removing tobacco smell is capable of achieving the best tobacco-smell-removing effect in the shortest period of time in the same area of application.

Description

technical field [0001] The invention belongs to the technical field of filter materials, and in particular relates to a filter material with the function of removing smoke. Background technique [0002] Non-woven filter materials play an indispensable role in human life and are widely used in various fields. In order to meet the various needs of different fields, a variety of filter materials with different performances have also emerged as the times require. With the sharp increase in the number of smokers, the gradual increase in smoking time and the enhancement of human health awareness, people have higher and higher requirements for the performance of filter materials in removing smoke, but the existing filter materials do not have better smoke removal performance. Taste performance. Because the existing smoke removal filter material only achieves the smoke removal performance through physical adsorption, even activated carbon with a certain chemical decomposition effe...
