Description of the invention (1) The invention is roughly based on a cigarette filter according to the preamble of item 1 of the scope of the patent application. Owing to the concept, cellulose lip is increasingly used to form cigarette filters. In addition to the design of light and light cigarettes, licking is often the preferred choice because of its good retention. However, one of the main disadvantages of cellophane or paper lapping is the adverse effect of a paper filter on the taste, while cellulose acetate lapping has no such adverse effect; instead, they are used together with other filter materials to form Double, duplex or multiple filters. But making such multiple mouthpieces is quite complicated and expensive. On the other hand, cellulose acetate filters with a degree of acetylation of 2.0 or above have encountered problems with biodegradation. If the degree of acetylation is less than 2.0 * such as 1.7 or even as small as 1.5, the filter material is almost decomposed As good as paper (cellulose), however, there is currently no mass production method available / to manufacture such cellulose acetate filters that can be used to manufacture cigarette filters. An object of the present invention is to provide a new filter material for a single filter or a single piece of filter with the same retention as a multiple filter. Another object of the present invention is to provide a method for manufacturing such a filter material. This is achieved by the features described in item 1 or 17 of the patent application. In the present invention, helixin acetate is coated on a sheet of paper by a melt-blowing method, which combines the good retention of cellulosin with the selective retention of acetaminophen acetate. This material, if formed into a single filter, is surprisingly -4-This paper size is applicable to China National Standard (CNS) A4 (210X297mm) ~ " " (Please read the notes on the back first Fill in this page)-定 -Γ 321595 at B7 5. Description of the invention (2) It has the same retention and taste properties as the general multiple filter with the same general preservation. The manufacture of this new filter material can be carried out in a melt-blowing method by using a multi-layer structure with a preferably single layer and having 8 to 50 g / cm2 * and 15 to 30 g / cm2 as the preferred smooth or crepe paper sheet. to make. The degree of acetylation of the melted and blown cellulose acetate is 1.0-3.0, preferably 1.7-2.6 * and the fibers formed by the melt blown method are quite brittle and usually do not combine to form a filter material . However, in the present invention, the cellulose acetate filter is treated with triacetin to soften the outside of the fibers, so that they are softened at the periphery and bonded at the area where they touch and simmer together. This completes a suitably entangled halogen filter material that can be processed to form a cigarette filter. Depending on the volume range of paper / cellulose acetate, a binder can be advantageously used. This binder can be a sticky agent or, for example, denatured extrudable and meltable starch, starch is preferred for ecological reasons. In each case, care must be taken so that the processing temperature does not affect the later coated cellulose fibers. ---------- 〇— • * (please read the note $ item on the back and then fill in this page).
