Summary of the invention
Subject to be solved by the invention
Such as when making filter substrate in the array processes of one of the production technology of TFT LCD, pollute glass The problems such as open circuit, can occur for the case where glass plate surface.Because while filter substrate is with sputter or vacuum deposition method etc. in glass The films such as semiconductor film, ito film (transparent conductive film), insulating film, aluminum metal film are formed in glass plate, once but glass pane surface There are when polluter, will occur to break or because short circuit occurs for the defect of insulating film on the circuit board formed by film.Separately Outside, in the production of filter substrate, pattern is formed by photoetching on a glass, but once applies lighting in this process There are polluters on glass-board surface when photoresist, will generate pin hole, result meeting on photoresist film after exposure and development Open circuit or short circuit occurs.Also same problem is confirmed when manufacturing organic el display.Organic el display is to pass through sputter Or vapor deposition or printing form the film of ito anode, organic luminous layer, cathode etc. on a glass, exist in glass pane surface and hinder Hinder the foreign matter of film, it may occur that non-luminous problem.
Although the pollution cause of this glass plate is difficult to determine, found out its reason from glass plate first is that pad The surface of paper is transferred to the fine foreign matter on the surface of glass plate.
In addition, defined such foreign matter first is that organic silicon substance.
But when glass plate to be clipped between glass plate with interleaving paper, when the physics shape on the surface of interleaving paper front and back sides When state has differences, it is sometimes desirable to which consideration contacts the particular surface of interleaving paper with the surface of glass plate.For example, in order in plane The surface of the glass plate of display is formed with fine circuits, especially to evade the attachment even micro foreign matter, still, because Once than another surface, there are more foreign matters on a surface of such glass plate interleaving paper, then the foreign matter is to glass plate table The risk of face transfer just will increase, so being considered as making the surface of the few foreign on the surface of glass plate and interleaving paper rather than deposit It is contacted on the surface of many foreign matters.At this moment, it is pressed from both sides between glass plate into two interleaving papers, we are general to consider each interleaving paper A less surface of foreign matter amount is towards glass plate in surface, but because the usage amount of interleaving paper increases, interleaving paper and The weight of glass plate laminate increases, so from the point of view of operating aspect, not preferably.
Project of the invention is the above problem caused by the positive and negative surface state difference of solution glass plate interleaving paper causes.Especially It is that the subject of the invention is to provide a kind of front and back sides can be with the glass plate interleaving paper of contact glass sheet.
The means to solve the problem
Then, it through further investigated, as a result present inventors found that, reduces contained in glass plate interleaving paper containing organic The content of foreign matter in the silicon of silicon, and difference by controlling the foreign matter content contained by the interleaving paper front and back sides controls glass plate With the difference of the positive and negative surface state of interleaving paper, can provide a kind of front and back sides can pad with the glass plate of contact glass sheet Paper, so as to complete the present invention.

L Water Paper preparation section is dehydrated the sheet material to form l Water Paper；And
Drying process, the dry l Water Paper is to obtain interleaving paper.
The sheet material two sides is dehydrated in the l Water Paper preparation section.
The dehydration is carried out preferably by suction.
The suction dehydration ratio of the suction dehydration ratio and another surface on one surface of the preferably described sheet material 10% of the difference of rate lower than Smoking regime dehydration ratio described on another surface.
The preferably described manufacturing method include one it is additional aspirate process, to the two sides of the interleaving paper after the drying process into One step is aspirated.
In addition, the laminated body is the glass plate of first embodiment of the invention the invention further relates to a kind of laminated body With interleaving paper and the laminated body of glass plate.
In addition, the invention further relates to a kind of glass plate guard method, comprising one by the glass of first embodiment of the invention Glass plate is configured at process between glass plate with interleaving paper.
Invention effect
The amount of machine silicon contained in glass plate interleaving paper of the invention is seldom, also, can inhibit the positive and negative of the interleaving paper The number of the discontinuity zone containing organosilicon in face is different, so that inhibit glass plate interleaving paper front and back sides contains organosilicon Foreign matter existence it is different.Therefore, the front and back sides of glass plate interleaving paper of the invention can be with contact glass sheet.By This, the operability of glass plate interleaving paper of the invention is excellent.
In addition, though glass plate is wound into scroll-like factory with interleaving paper, but because in this reeling condition Lower liner recto is contacted with reverse side, thus for example when the positive few foreign containing organosilicon and reverse side contains organosilicon Foreign matter it is more when, even if liner recto is contacted with the surface of glass plate, under reeling condition, the silicon of the reverse side of interleaving paper In the foreign matter containing organosilicon can be transferred to front, it is possible to the positive cleanliness can be reduced.
But even if it can also inhibit containing the different of organosilicon because glass plate interleaving paper of the invention is wound into roll Object is transferred to another surface from a surface of interleaving paper, thus without having to worry about be wound into roll will cause interleaving paper surface it is clean Cleanliness decline.
And glass plate interleaving paper of the invention is few because of the foreign matter amount containing organosilicon, can effectively press down System even avoids the fine foreign matter as problem from being transferred on glass plate from the interleaving paper.In this way, even be kept away by control Exempt to be transferred on glass plate as the fine foreign matter of problem, can prevent colored in the manufacturing process of TFT LCD etc. The circuit breaker of film etc..
