Abstract

The invention concerns a filter material which is suitable in particular for producing cigarette filters. The material is characterized in that molten softened cellulose acetate is applied by the melt blown technique to a strip of prefabricated filter paper.

Description

Cigarette filter
The present invention relates to the cigarette filter that preamble is narrated in the claim 1, and relate to the method that preamble is narrated in the claim 17.
From basic conception, the cellulose filtering material is used for cigarette filter more and more.For the design of flat taste and ultra-light's cigarette (Leicht-und Ultra-Leicht-Cigeretten), adopt paper to make filter tip more, this is because paper has extraordinary retention characteristics.But compare with normally used cellulose acetate filter, its major defect is the variation that the paper filter tip can cause taste.So the paper filtering material is not suitable for being used for the single-filtering mouth.Make so-called pair of filter tip, compound filter tip or multi-filtering mouth and only can be used from other filtering materials one.But the manufacturing of multi-filtering mouth is complicated especially, and cost is very high.
The purpose of this invention is to provide the method that a kind of filtering material and manufacturing are used for the filtering material of cigarette filter, it has the advantage of cellulose acetate and paper concurrently.
Claim 1 and 17 characteristic separately can be used for reaching this purpose.
According to the present invention, cellulose acetate is coated on the paper tape with meltblown.Just have both the selection retention characteristics that cellulosic good retention characteristics and cellulose acetate are arranged thus.Be surprised to find that, with the single-filtering mouth of this material manufacturing suitable aspect retention characteristics and the sense of taste characteristic with common multi-filtering mouth with identical total holdup rate.The preparation of this new filtering material can be adopted meltblown and use smooth paper tape or the paper tape of pre-wrinkleization mistake realizes that paper tape preferably keeps flat with individual layer with multilayer, and its weight range is 8～50g/m 2, be preferably 15～30g/m 2, the degree of the acetoxylation of the fusion cellulose acetate of ejection is 1～3, is preferably 1.7～2.6.Preferably a kind of cellulose acetate of handling with glyceryl triacetate plasticising of this cellulose acetate, the surface of the softening cellulose acetate of glyceryl triacetate makes fiber bonding mutually at infall or contact position.
According to the usage ratio situation of paper to cellulose acetate, it is favourable using a kind of bonding agent.This bonding agent can be a kind of melting adhered material or a kind of extrudable and fusible starch slurry of modification for example.From economic angle, the latter is recommendable.But all essential in all cases attention, the processing temperature of bonding agent can not influence the performance of the cellulose fibre of coating thereafter.
