Abstract

The utility model relates to a non-woven fabric cigarette filter tip which adopts thin non-woven fabric as the raw material of a filter core, and the raw material of the filter core and paper wrapping material are rolled into the cigarette filter tip on a filter tip shaper. The utility model has the advantages that the home-made non-woven fabric material is used for replacing the imported acetate fibre tow, which breaks the bad condition that the material resource of the Chinese cigarette filter tip depends on the import for a long time, saves a large quantity of foreign exchange and lowers the price of filter tips. Each index of the filter tip produced by the utility model reaches the qualified standard through the test.

Description

Nonwoven cloth cigarette filter-tip

A kind of nonwoven cigarette filter tip rod, it is formed by crossing filter core and papery lapping.

The cigarette filter tip rod that present domestic each cigarette factory generally uses is crossed filter core, be with acetate silk, add triacetin fat emulsifying agent expanded after, on the filter rod make-up machine, roll into cigarette filter tip rod with lapping, but can't produce acetate silk owing at present domestic, can only rely on a large amount of acetate fibre filament raw material of import to keep each cigarette factory and produce cigarette with filter tip, spend a large amount of foreign exchanges, filter rod price one be risen rise again.

Also have at present and utilize natural fiber material to make cigarette filter to cross filter core for raw material, for example: with the papery of cotton and bombax cotton and staple fibre be mixed into raw material and make cigarette filter tip rod and cross filter core, but there is the short and thick defective of fiber itself in natural fiber material, the filter rod resistance to suction of making is big, the uniformity is poor, waste product is many connecing on the cigarette equipment, and after the natural fiber bleaching degreasing very strong water imbibition is arranged, the moisture content that produces during smoking is very fast to be absorbed by filter rod, high humidity and gas permeability subtracts greatly, through the test of cigarette factory, poor effect.

The purpose of this utility model is: adopt a kind of new homemade fibrous material to make cigarette filter tip rod and cross filter core, break the cigarette filter tip rod of China's cigarette factory dependence on import acetate fibre filament processing for a long time and cross the bad situation of filter core, and every index of cigarette filter tip rod is all met the requirements.

The purpose of this utility model is achieved like this: cross filter core and adopt pressure at 25-35kg/cm ², the thin non-woven fabric produced under 160 ℃ of-275 ℃ of conditions of temperature is raw material, on the cigarette filter rod forming machine, once rolls into cigarette filter tip rod with the papery lapping.

The filter core of crossing of the present utility model is to make with pure polypropylene short fiber nonwoven, or makes with pure polyester staple fiber nonwoven, and also available to contain two kinds of fibers be that polypropylene short fiber accounts for 10-100%, and polyester staple fiber accounts for 0---90% nonwoven is made; The filter core of crossing of the present utility model can be that the nonwoven of the compound short fiber of the main 30%-50% of adding is made in order to polypropylene short fiber yet, or is that the nonwoven of two acetate staple fibers of the main 30-50% of adding is made in order to polypropylene short fiber.

The thinness of crossing the used nonwoven of filter core of the present utility model be the 15-40 gram/square metre.

The drawing of accompanying drawing is described as follows:

The front view of Fig. 1, cigarette filter tip rod.

The cutaway view of Fig. 2, cigarette filter tip rod.

As shown in Figure 1 and Figure 2, the utility model is once to be rolled on the cigarette holder make-up machine by the excessively filter core (2) that papery lapping (1) and nonwoven are made to form.

This cigarette filter tip rod is crossed filter core and should be satisfied when selection: the employed material of the nonwoven of selecting is harmless, and free from extraneous odour when inhaling, and requires nonwoven production factory when the processing nonwoven, takes pressure to be controlled at 25-35kg/cm²Between, temperature is controlled under 160 ℃ of-275 ℃ of conditions, so that fiber keeps its original elasticity basically, the strainability of crossing filter core with the cigarette filter tip rod that guarantees to make is good.

Embodiment 1: it is 25kg/cm that the mistake filter core is selected pressure for use ², temperature is that the pure polypropylene short fiber nonwoven of producing under 160 ℃ of conditions is a raw material, is cut into four width of cloth rolling with 38cm, grasps per 10 heavy 9.5 grams, the molding machine once rolls with the papery lapping and to form.

Embodiment 2: it is 35kg/cm that the mistake filter core is selected pressure for use ², temperature is that the pure polyster fibre nonwoven of producing under 275 ℃ of conditions is a raw material, is cut into two width of cloth rolling with 40cm, grasps per 10 heavy 9.5 grams, the molding machine once rolls with the papery lapping and to form.

Embodiment 3: crossing filter core is that polypropylene fiber accounts for 10-100% with containing two kinds of fibers, the nonwoven that polyester staple fiber accounts for 0-90% is a raw material, be cut into four width of cloth rolling with 38cm, grasp per 10 heavy 9.5 grams, once roll on make-up machine with the papery lapping and to form.

Embodiment 4: crossing that filter core adopts with the polypropylene short fiber is that the nonwoven of compound short fiber of the main 30-50% of adding is a raw material, is cut into two width of cloth rolling with 40cm, grasps per 10 heavy 9.5 grams, once rolls on make-up machine with the papery lapping to form.

Embodiment 5: crossing that filter core adopts with the polypropylene short fiber is that the nonwoven of two acetate staple fibers of the main 30-50% of adding is a raw material, is cut into four width of cloth rolling with 38cm, grasps per 10 heavy 9.5 grams, once rolls on make-up machine with the papery lapping to form.

Adopt the made cigarette filter tip rod of the utility model, realized replacing with domestic raw material-third polyster fibre nonwoven the purpose of imported raw material-acetate silk, social and economic benefits is very considerable, and through relevant department's test, the indices of this cigarette filter tip rod all reaches required standard.
