Description
Technical field
The invention belongs to papermaking and tobacco business fields, are related to a kind of common filter stick shaping paper and its production technology.
Background technology
When filter stick shaping paper is processing filter stick for cigarettes, for rolling up the dedicated paper of packet filter material, applied to being wrapped in cigarette filter
Acetate silk is wrapped up in, is between internal acetate silk core and outer layer cork paper in cigarette filter constructions.Mainly have
Common filter stick shaping paper and high saturating filter stick shaping paper.There is no the filter stick shaping paper of particular/special requirement to air permeability common filter rod forming
Paper；There is the filter stick shaping paper being distinctly claimed to air permeability high saturating filter stick shaping paper.
Cigarette microcapsule essence technology, with the development of low-coke tar cigarette, the fragrance of tobacco in itself is by filtering and dilutes,
Fragrance seems apparent deficiency that flavoring not only can overcome the disadvantages that these losses, but also not increase tar yield.The flavoring of cigarette product is formula
One important link of design is the effective means for improving cigarette product quality, is the particularly important means of cigarette industry, is volume
One of core technology of cigarette enterprise and its secrecy.The essence capsule of addition package unique perfume, is smoking in cigarette filter tip rod
Before pinch brokenly essence capsule, ooze out the oiliness essence in capsule, improve smoking when fragrance.But oiliness essence is easy to infiltration filter
Stick forming paper, causes filter rod to pollute, while may make bonding place explosion of the filter stick shaping paper in package tow again.
In order to coordinate the demand of tobacco enterprise, the present invention develops a kind of common filter rod forming of the antiseepage with oleophobic property
Paper, this filter stick shaping paper can effectively prevent the essential oil exudation filter stick surface in filter rod.
Application publication number：105887569 A of CN disclose a kind of grease proofing saturating forming paper of height；105862506 A of CN are disclosed
A kind of grease proofing forming paper production technology, the technique include：Wood pulp size degradation, mashing, it is with slurry, manufacture paper with pulp, be Top wire former, squeezing, preceding
Road drying, sprinkling auxiliary agent, table glue, the drying of rear road and coiling process.Above-mentioned technique shortcoming has：1st, sprinkling oil-proofing agent it is more difficult
It is sprayed uniformly on same paper, while sprinkling can only generally be sprayed at single side, another side is more difficult grease proofing effect；2nd, spray pattern
Oil-proofing agent is made to have larger loss, is unfavorable for cost-effective；3rd, spray pattern is unfavorable for controlling keeping for oil-proofing agent, cannot guarantee that
There are enough oil-proofing agent additive amounts；4th, sprinkling auxiliary agent can be destroyed paper appearance and planarization；5th, it touches and spills oil-proofing agent and table
Glue size-press starch combines and is extremely difficult to satisfied oleophobic property anti-seepage effect.
In view of above deficiency and difference, now provide a kind of new common filter stick shaping paper of oleophobic property antiseepage and its production work
A solution of skill.
