Description
Technical field
The present invention relates to a kind of tea filter paper, relate in particular to a kind of two-sided heat-sealing filter paper that is used for the tealeaves making double-bag and preparation method thereof.
Background technology
Tea filter paper is a kind of filter paper commonly used, is used for tealeaves and filters, and people are tired of in the tealeaves come-up and the surplus tea that falls when daily having tea, and have produced tea bag, also are used for compatriots certainly and fry in shallow oil Chinese herbal medicine, and are suitable especially.
Tea filter paper is divided into heat-sealing type and divides heat-sealing type, and difference is exactly whether to have used heat-sealable material.Heat-sealable material is generally made fibrous, mixes with paper pulp and copies, and carries out HEAT SETTING behind the one-tenth paper, promptly at high temperature allow heat-sealable fiber be shrunk to point-like, when tea bag was packed, the heat-sealing material of these point-like was sticking mutually with the heat-sealable fiber of another side when being heated then, paper is just got up by envelope like this, can form tea bag.
But this bag can only be made single bag, but people are in order further to accelerate the tea delivery speed of tea bag, the contact area that improves tea bag and hot water is a good method, two capsule bags have just been designed, but this bag needs the two-sided of paper to seal, and present this paper is the demand for development that can not satisfy the user.
Summary of the invention
In order to solve the defective that exists in the two capsule bags manufacturings of above-mentioned tealeaves, one object of the present invention provides a kind of two-sided heat-sealing filter paper that is used for making double-bag, and this heat-sealing filter paper has been realized two-sided heat-sealing, and it is good to have two capsule bag formings, heat seal strength is good, preparation technology's characteristic of simple.Another object of the present invention provides the preparation method of the above-mentioned two-sided heat-sealing filter paper that is used for making double-bag.
For first purpose on realizing, the present invention has adopted following technical scheme:
The two-sided heat-sealing filter paper that is used for making double-bag, this two-sided heat-sealing filter paper is made of main heat cover and time compound paper of copying of heat cover, wherein contain polypropylene fibre in the papery of main heat cover, the addition of polypropylene fibre is 20%～50% of a main heat cover paper fiber total amount, contain in the papery of inferior heat cover polyethylene fiber or or contain poly composite fibre, polyethylene fiber or or the addition that contains poly composite fibre be 10%～40% of the paper fiber total amount of time heat cover.
As preferably, the addition of above-mentioned polypropylene fibre is 22%～35% of a main heat cover paper fiber total amount, and polyethylene fiber or the addition that contains poly composite fibre are 17%～28% of the paper fiber total amount of time heat cover.
As preferably, the above-mentioned poly composite fibre that contains is the ES composite fibre.
As preferably, contain polyethylene fiber in the papery of above-mentioned inferior heat cover, polyethylene fiber be time heat cover the paper fiber total amount 15%～40%.
For second purpose on realizing, the present invention has adopted following technical scheme:
A kind of preparation method who prepares the above-mentioned two-sided heat-sealing filter paper that is used for making double-bag, this preparation method adopts the moulding of oblique net paper machine, wood pulp polypropylene fiber is adopted on the upper strata, and lower floor adopts wood pulp mix polyethylene fiber or contains poly composite fibre, the compound paper of copying of upper strata lower floor.
Perhaps, above-mentioned preparation method adopts cylinder, tiltedly net papermaking unit mahine moulding, and wood pulp polypropylene fiber is adopted on the upper strata, and lower floor adopts wood pulp mix polyethylene fiber or contains poly composite fibre, upper strata, the compound paper of copying of lower floor.
The present invention is owing to adopted above-mentioned technical scheme, because in the manufacturing process of two capsule bags, heat-sealing requirement to the two sides is different, so former single face adds on the basis of heat-sealable fiber PP fiber, we think that another side can select more low-melting heat-sealable fiber, for example PE or ES composite fibre, the heat resisting temperature of PE fiber is 128 ℃, experimental results show that it is the preferable fiber suitable with the PP fiber, the ES composite fibre is the composite fibre of PE and PP, because it has 128～165 ℃ of wide heat-sealing temperature scopes, therefore can be better than the PP fiber to a certain extent.
The heat-sealable fiber addition of main heat cover is generally greater than 15%, and being lower than 15% can influence heat seal strength; Can not be higher than 60%, more than 60% o'clock, behind the heat-sealable fiber hot melt, can make paper hole occur, for anti-occur hole must increase paper quantitatively, and quantitative increase the time, heat-sealable fiber also increases thereupon, too much heat-sealable fiber can make low can not the use as tea filter paper at the surface filming of paper.
The heat-sealable fiber of inferior heat cover is generally selected the fiber lower than the hot melting temperature of interarea for use, the interarea heat-sealable fiber is generally used PP, inferior face is generally with PE or adopt the ES fiber, the heat-sealable fiber consumption of inferior heat cover generally is lower than main heat cover, reason is that the heat seal strength of time heat cover is generally less demanding, need not to bear the tension force that expands generation when tealeaves is heated, it is just passable only to need the two sides is sticked together.
Former single face adds on the basis of heat-sealable fiber, also added heat-sealable fiber at another side, this process seems simply, but owing to exist the program of HEAT SETTING, in HEAT SETTING, general string laminating hot cylinder, the surface temperature of hot cylinder is generally about 180 ℃, and the general the highest heat resisting temperature of PP heat-sealable fiber is at 165 ℃, if there is heat-sealable fiber pasting the cylinder face, heat-sealable fiber can be transferred on the cylinder, forms sticking cylinder.So for the energy two-sided heat-sealing, it also is necessary changing the typing mode, we select drying tunnel formula drying mode.
