Abstract
The many tow that a kind of employing will be extracted out carry out drawing-off simultaneously, the cigarette polypropylene fiber tow production method of the two step method that then finalize the design with the wall scroll tow more respectively and curling etc. afterwards processed.
This method does not have chemical reaction process, three-waste free discharge, can not produce and pollute environment, the disposable small investment of founding the factory, technology is simpler, use the prepared polypropylene tows system cigarettes of the inventive method filter tip, its cigarette product flue gas analysis leading indicator is near the filter-tip performance of diacetate fiber, and smoking result and diacetate fiber filter tip do not have significant difference.
Description
The present invention discloses a kind of cigarette production method with the polypropylene tow, mainly by screening back polypropylene resin melt spinning, drawing-off, Steam Heating, drawing-off, oil, curl, operations such as seal wire, typing form, and belong to the method for making synthetic fibers
Cigaratte filter generally adopts diacetate fiber tow preparing dress at present.The technological process of production of diacetate fiber tow is longer.Its primary raw material is the cotton linter of cellulose material of nature growth and timber etc., and is resource-constrained.Simultaneously, also to produce serious corrosion and pollution to equipment and environment aborning with industrial chemicals such as a large amount of acetic acid, acetone and caustic soda.These unfavorable conditions have limited the expansion production of diacetate fiber tow.Under the situation of diacetate fiber tow production atrophy and the surge of system cigarettes filter tip materials, countries in the world are all in the substitute of seeking the diacetate fiber bundle.Wherein, polypropylene tow prospect is quite wide.But, since the production method difference, the technological process of production difference that is promptly adopted, different with selected main production equipments, and resulting technical-economic index also can't reach a standard fully, and therefore, cigarette polypropylene fiber tow does not still have ripe industrial process to come out.
The invention provides a kind of small investment of founding the factory, environment is not produced corrosion and pollutes, is raw material with the foodstuff sanitation-stage polypropylene resin, produces the method for cigarette with filter filament.
Cigarette is to adopt many tow will extracting out to carry out drawing-off simultaneously with polypropylene tow production method, the two step method that then finalize the design with the wall scroll tow more respectively and curling etc. afterwards processed.Divide the two large divisions, form by following operation altogether;
A, the preceding Ministry of worker that adds
A, spinning
Screening back polypropylene resin enters extruder, and melt temperature is 230～250 ℃ and adopts Shaoyang second textile machinery factory product to have the spinning of six mouth silk heads (spinning station) spinning-drawing machine;
B, branch silk
With spun each tow of six spinning stations of spinning-drawing machine, introduce drafting machine respectively through minute guide frame and carry out drawing-off;
C, drawing-off and Steam Heating
Every tow is introduced into the slubbing drafting machine, 20～40 meters/minute of its hauling speeds, and 50～120 meters/minute of two road drafting machine hauling speeds, draw ratio 2-3 times, Steam Heating oven temperature, degree is 150～160 ℃;
D, oil
Tow enters oiling machine and oils after drawing-off, and oil concentration is 1～2%, and room temperature oils, and adopts the LD-650 finish
E, turn to
The back tow that oils turns to through the slewing rollers of different angles, is imported the pendulum wire machine by godet;
The f pendulum wire
The pendulum wire machine that adopts Shaoyang second textile machinery factory to make carries out pendulum wire:
B, after add the Ministry of worker
A, the heating of seven rollers and insulation
The tow of pendulum wire, the silk back vanning that falls is drawn, go into seven roller heater, 120～130 ℃ of temperature through advancing guide frame; Tow after the insulation is sent into crimping machine again;
B, curling
Curling process speed 50-120 rice/minute
C, conveying and pendulum wire
Tow through curling is delivered on the conveyer belt naturally, is transferred to the pendulum wire machine, carries out pendulum wire, silk and packing falls.
Cigarette provided by the invention polypropylene tow production method, employed equipment all adopts Shaoyang City second textile machinery factory to make according to the requirement of producing the polypropylene fibre cigarette filter filament, as spinning-drawing machine, drafting machine, pendulum wire machine, crimping machine, forming machine and cooling calibrator etc.
Use the inventive method, produce cigarette with the polypropylene tow process in, no chemical reaction does not also produce and discharges harmful waste residue, waste liquid and waste gas, does not pollute the environment.The disposable investment of founding the factory is less, and production technology is also easier, uses cigarette polypropylene tow preparing picked cigarette filter tip, and its cigarette product flue gas analysis leading indicator is near the filter-tip performance of diacetate fiber.Smoking result and diacetate fiber filter tip do not have significant difference.
Leading indicator is as follows:
Two groups in two groups of acetic acid mouths of one group of polypropylene fibre of one group of acetic acid mouth of polypropylene fibre
Pressure drop (H
2O/mm) 134.3,89.95; 97,110;
Nicotine (mg/ props up) 0.68,0.82; 1.02,1.06;
Tar (mg/ props up) 20.21,21.96; 23.29,22.92;
Filter efficiency (%) 34.60,23.00; 22.73,22.63;
Be described in detail the most preferred embodiment of the inventive method below.
The process of present embodiment divides two partly, wherein:
A, the preceding Ministry of worker that adds
A, spinning
Screening back polypropylene resin enters extruder, the extruder temperature be 230～250 ℃ with the resin fusion, by measuring pump, enter HPO21 type spinning-drawing machine spinning head and carry out spinning, 230～250 ℃ of spinning-drawing machine temperature.Have six spinning heads, i.e. six positions, hole count 8000～10000 holes of spinning head;
B, branch silk
With the every tow that six spinning stations of spinning-drawing machine are produced, introduce HPO21B(A respectively through minute guide frame) the type drafting machine, every tow interval 75～80mm;
C, drawing-off and Steam Heating
20～40 meters/minute of slubbing hauling machine hauling speeds, 50～120 meters/minute of two road drafting machine hauling speeds, draw ratio is 2.5～3.0 times, Steam Heating oven temperature, degree is 150～160 ℃;
D, oil
Oil concentration is 1.5%, and room temperature oils.Adopt CMC LD-650 finish to make the outside cladding of tow thin film, to improve filter efficiency;
