Description

A kind of filter bag filter paper and tealeaves filter bag and tea bag
Technical field
The present invention relates to field of papermaking, relate in particular to a kind of filter bag filter paper and tealeaves filter bag and tea bag.
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.If thickness is a little bigger, we also pack sorbing materials such as drier, carbon with the material of this tool strainability.
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.Certainly, except bag tealeaves, also can wrap other material, as materials such as carbon granules, carbon dust, drier.
The present more use polypropylene fibre of this heat-sealable fiber (PP), polyethylene fiber (PE), composite fibre oil products such as (ES).Owing to use oil product, in energy-intensive today, not enough environmental protection just seems, simultaneously, the environment friendly of oil product is very poor, and the PP fiber is in natural environment, centuries is all non-degradable, oil product can not be regenerated simultaneously, is disposable resource, and it is necessary using the friendly product of a kind of non-petroleum environments that can seal.
Summary of the invention
In order to solve the defective in the above-mentioned background technology, an object of the present invention is a kind of filter bag filter paper, this filter bag filter paper adopts acid fiber by polylactic, is a kind of heat-sealable material of wide temperature, adaptive capacity to heat sealing machine is strong, has complete Natural Circulation and the biolytic characteristics of energy.Another object of the present invention provides the application of above-mentioned filter bag filter paper.
In order to realize first above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of filter bag filter paper, this filter paper comprise that main body paper pulp fiber and heat-sealable fiber mix and copy made of paperly that described heat-sealable fiber adopts acid fiber by polylactic, and acid fiber by polylactic accounts for 10%～45% of whole total fiber mass.
As preferably, above-mentioned acid fiber by polylactic accounts for 15%～30% of whole total fiber mass.
As preferably, above-mentioned filter paper quantitatively be 16.5～45g/cm 2
The another name of acid fiber by polylactic of the present invention (PLA fiber) belongs to aromatic polyester fiber, but does not contain aromatic rings.Its synthesis material is the new generation of environment protection polyethylene terephthalate from natural plant (as corn etc.).Zein fiber imbeds in the soil that intensity can disappear and degrade after 1 year, buries if pile with other discarded object, and some months just can decompose, and catabolite is harmless lactic acid, carbon dioxide and water, does not produce noxious material during burning.Acid fiber by polylactic is a kind of synthetic fiber of fully biodegradable, and it can be obtained from cereal (as corn etc.).At first raw materials such as corn are fermented and make lactic acid, make PLA through condensation, polymerisation then, utilize couplant to make to have the PLA of the higher molecular weight of good mechanical properties again, pass through crucial chemical modification at last, its intensity, water-retaining property are promoted, and with its fibration.Because lactic acid is the natural materials that is present in animal, plant and the microorganism, be easy to natural degradation, this fiber does not use industrial chemicals such as oil fully, under the microbial action of its discarded object in soil and seawater, can resolve into carbon dioxide and water, finish Natural Circulation, can not distribute poison gas, can not pollute earth environment.Because the initial feed of this fiber is cereals such as corn, its regeneration cycle cycle is short, is approximately 1～2 year, and the carbon dioxide of its generation is owing to photosynthesis of plant, and the content in atmosphere can reduce gradually.Zein fiber is made raw material with the many starch of inexpensive amount, has complete Natural Circulation and the biolytic characteristics of energy again.Begin to soften during 60 ℃ of zein fibers, fuse fully in the time of 175 ℃, can be used as a kind of heat-sealable material of wide temperature, strong to the adaptive capacity of heat sealing machine.
The addition of zein fiber generally is controlled at 10%-45%, is lower than 10%, and the heat seal strength of paper is bad, and the tea bag sealing part ftractures easily, is higher than 45%, and cost rises and the possibility of film forming is arranged.Best addition should be controlled at 15%-30%.
