Cigarette Filters

The cellulose acetate oakum in a cigarette filter is a net of fibres produced from wood pulp. In production, the filter material comes as an individual long band of more than 10,000 fibres tighten up into large 750 kg bales. In a special filter maker machine, this band of compressed fibres is automatically stretlengthened to open the fibres up, diffused with a particular plasticizer to tie up them together, twisted with thin paper, cut, and directed into a cigarette-making machine.

Once the cigarette taste has been established, other characteristics can change the strength of the tobacco taste, and can even decrease the yields of different smoke elements, as assessed by a unique machine approach.

The design and style of the filter can be diverse, for instance by creating perforations, by modifying its length or either its density (by implying more fibres) by the great quality of the fibres and by the sort of material utilized.  All of these filter forms can influence the degree of filtration, and therefore the taste, smoking experience and smoke yields as calculated by a special machine approach.
Charcoal is often mixed with the ordinary cellulose acetate, as its adsorption qualities can decrease some of the gas elements in smoke.  It is generally applied in a filter with two areas: a plain white cellulose acetate area at the mouth end and an area that has been spread with charcoal.  Since charcoal is primarily much needed carbon, these are occasionally known as carbon filters.

Creating tiny perforations in the filter is identified as filter ventilation, to decrease a cigarette’s yield and sensory toughness.  These dilute the smoke with air, contributing to less smoke being generated in each puff.  Filter ventilation is crucial in decreasing smoke gases that are not captured in the filter.

As about the paper used around the tobacco rod and around the filtration sector it can be modified.  The porosity of the paper will significantly impact the robustness, taste and flavor of the cigarette. The more air that can circulate through the paper, the more the smoke components moving through the cigarette is diluted, to assure a lesser yield, finer tasting product.
