Problems solved by technology

However, the disadvantage is its high price, which hinders its use in practice
Although this patent application describes the low pressure loss of cigarette filters, based on what is known about the properties of nanofiber fabrics, it cannot be consistent with this argument, instead it can be assumed that the pressure loss of cigarette filters formed of nanofibers will be high

Embodiment Construction

[0027] exist figure 1 In the case of the cigarette 1 shown in , a cigarette filter 2 is manufactured by a tubular body, one face of which is attached to the tobacco tubular part 3 of the cigarette and the second face is the free face. It is known from the background art that the tubular body of a cigarette filter is formed from a fiber cord or a system of fiber cords which are essentially parallel fibers, and finally from a system which is essentially parallel threads or threads, and the fibers, threads or threads which flow through the filter The direction of the smoke is oriented parallel, and they are made of fibers, the diameter of which varies from 1 micrometer to 40 micrometers, and therefore they will be called microfibers 21 subsequently. According to the invention, nanofibers 22 are arranged in these microfibers 21 in amounts of up to 10% by weight. At the same time, it is advantageous to have the nanofibres 22 in the microfibres 21 arranged uniformly throughout the ...

Abstract

The invention relates to the cigarette filter containing the microfibres (21), which contains from 0,5 to 10 % by weight of polymeric nanofibres (22), that are arranged among the microfibres (21). At manufacturing of cigarette filter containing the microfibres (21), the nanofibres (22) or shreds (23) of surface nanofibrous textile are brought to the surface of a configuration designated for production of the cigarette filter (2) formed at least of 90 % by weight of microfibres (21), and they are deposited onto the surface and / or into the volume of the configuration in a quantity from 0,5 to 10 % b weight.

Description

technical field [0001] The present invention relates to cigarette filters comprising microfibers and methods for their manufacture. Background technique [0002] The function of the cigarette filter is to capture the components harmful to health in the cigarette smoke, especially the organic substances produced in the incomplete combustion of tobacco and cigarette paper. Filters are mainly made of filter matter or more precisely of crepe paper or its fibrous cords or systems of essentially parallel threads or filaments, while all implementations are made of microfibres of a material that has a minimal impact on the "taste" of the cigarette , such as cellulose acetate. At the same time, it is necessary that the material and construction of the cord and the rest of the filter do not lead to a significant pressure gradient increase between the ends of the filter, which has a decisive and negative effect from the consumer's point of view. [0003] The general trend is to incre...
