Siren, Rakuunantie 9, Helsinki, Suomi-Fin Country (FI) (Jk) Berggren Oy Ab (5) Fiber Material 1 - Suodatinaine The present invention relates to: The majority consists of one or more crosslinking agents, cross-linking agents, bifunctional agents with ionized strain cross-linked organic substances, especially polymeric carbohydrates or carbohydrate derivatives, hydroxyl group-containing polymers or non-synthetic cross-linked polymers. the skeleton of the filter material and at least one substantially uniformly distributed substance capable of substantially removing selectively from the vase passing through the filter at least one predetermined substance for its use.
Det bar under ärens lopp föreslagits ett stort antal olika tobaksfilterkonstruktioner och tobaksfilter-material. I allmänhet har dessas framgäng i vad avser avskiljning av de skadliga substanserna i tobaksröken värit langt ifran tillfredställande. Detta är i och för sig förklarligt med hänsyn tili de ur filtrerings-synpunkt svärartade forhällanden som föreligger vid exempelvis filtrering av cigarettrök. Röken kan anses 7) 10 vara aerosol och den innehaller 1Cr - 10 partiklar 3 2 67666 per cm , varvid partikeldiametern varierar fran 0,1 urn till ca 1 urn och partiklarnas medeldiameter under normala förhällanden uppgar till 0,5 - 0,6 urn.During the course of the event, a large number of different tobacco filter designs and tobacco filter materials were proposed. In general, their success in separating the harmful substances in the tobacco smoke has been far from satisfactory. This, in itself, is explained by the filtering conditions, which are difficult in the case of filtering cigarette smoke, for example. The smoke can be considered to be aerosol and it contains 1 Cr - 10 particles 3 2 67666 per cm, the particle diameter varying from 0.1 µm to about 1 µm and the average diameter of the particles under normal conditions amounts to 0.5 - 0.6 µm.
Den av dessa partiklar bildade partikelfasen i röken utgör ca 5 - 10 % av rökens vikt, medan sälunda resterande ca 90 - 95 # av röken utgör gasfas, vilken huvudsakligen bestar av syre, kväve, kolmonoxid och koldioxid. Vid passangen genom ett cigarettfilter är rökens hastighet sa storsom ca 55 cm/sek och rökens uppehällstid, under vilken den kan bringas i kontakt med filtermaterialet, är vid ett cigarettfilter med normal längd därför blott av storleksordningen 0,0d sek. Den f'iltret näende cigarettrökens temperatur okar under glödens närmande till xiltret fran unge-färligen rumstemperatur till 75 - 90°C.The particle phase formed by these particles in the smoke is about 5-10% of the weight of the smoke, while the remaining about 90 - 95% of the smoke is gas phase, which mainly consists of oxygen, nitrogen, carbon monoxide and carbon dioxide. When passing through a cigarette filter, the rate of smoke is approximately 55 cm / sec, and the smoke residence time, during which it can be contacted with the filter material, is therefore of the order of 0.0d sec in a normal length cigarette filter. The filter nested the cigarette smoke temperature rises during the glow's approach to the xilter from the approximate room temperature to 75 - 90 ° C.
Hittills har man använt flera olika substanser och flera konstruktioner som filtermaterial för gasformiga medier. En stor del av dessa filtermaterial har haft som aktiva medel olika organiska substanser, oorganiska salter och dessa fungerat som sadan som filtermaterial eller de har värit pä olika sätt bundna till bärar-material. Som bärarmaterial har man använt framför-allt aktivt kol, olika fibertyper, cellulosa, cellu-losaderivater o.s.v. Ingen av dessa tidigare beskrivna filtermaterial har visat sig vara riktigt adekvata, framförallt da man kräver stor effektivitet under en kort filtreringsperiod och under begränsade volym-förhällanden vad gäller filtermaterialets omfäng.To date, several different substances and several constructions have been used as filter material for gaseous media. A large part of these filter materials have had as active agents various organic substances, inorganic salts and these have functioned as such as filter materials or they have been linked in various ways to carrier materials. As the carrier material, mainly activated carbon, various fiber types, cellulose, cellulose derivatives, etc. have been used. None of these previously described filter materials has proven to be quite adequate, especially since high efficiency is required over a short filtration period and under limited volume conditions as to the extent of the filter material.
Detta speciellt da man tanker en sadan filtrerings-process som krävs t.ex. för cigarettfilter. En annan nakdel har funnits med dagens filtermaterial är att dessa har värit för dyra t.ex. för engängsändamäl. Föreliggande uppfinning har överraskande visat sig, att man har lyckats lösa ovanbeskrivna och andra nackdelar och man har fätt fram en effektiv, industri-ellt lätt framställbar relativt billig filtermateria.This is especially so when you consider such a filtration process that is required e.g. for cigarette filters. Another disadvantage with today's filter material is that these have been too expensive e.g. for single use purposes. The present invention has surprisingly been found to have solved the above-described and other drawbacks and to have produced an efficient, industrially readily produced relatively inexpensive filter material.
