DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present application relates to a method for manufacturing glass fiber fabrics, and particularly to a manufacturing method for efficiently deoiling glass fiber fabrics.

Glass fiber fabrics are usually used for various purposes such as printed circuit boards and FRP by weaving glass yarns to make glass fiber fabric raw fabrics, and then removing oil from the raw fabrics and subjecting them to surface treatment.

De-oiling the original glass fiber fabric is done by removing the starch adhering to the glass yarn, the sizing agent mainly consisting of oil, the starch during warping during the weaving process, and polyvinyl alcohol (
This is to remove the warp glue mainly composed of PVA).

There are wet methods, heating methods, etc. for deoiling glass fiber fabrics, but wet methods have disadvantages such as difficulty in completely removing organic substances such as sizing agents, and the tendency to cause misalignment of the fabric. The method currently commonly used is the thermal deoiling method.

〔発明が解決しようとする課題] ガラス繊維織物の加熱脱油は、鉄芯に巻いたロール巻の

[Problems to be Solved by the Invention] Glass fiber fabrics are deoiled by heating by placing them in a roll wound around an iron core in a batch-type heating furnace at 300°C to 450°C.
Heating for a certain period of time at a temperature of

温度が低すぎると脱油が充分におこなわれず、又、温度

維織物の強度低下もそれに比例する。
If the temperature is too low, oil removal will not be sufficient, and if the temperature is too high, the glass fibers will deteriorate significantly, and the strength of the glass fiber fabric will decrease proportionally.

脱油されたガラス繊維織物は、残脂量が0.1%以下と
なることが要求される。
The deoiled glass fiber fabric is required to have a residual fat content of 0.1% or less.

The heating time varies depending on the type of fabric and the winding length, but for example, in the case of a glass fiber fabric with a thickness of 0.2 mm and a length of 2000 m/roll, it will take about 70 minutes including the preheating time.
Requires time to heat. Therefore, during this time, the glass fiber fabric will remain in the heating furnace, and in order to compensate for the decrease in productivity due to this long residence time, it is necessary to increase the capacity of the heating furnace or increase the number of heating furnaces. There is.

Moreover, long-term heating naturally leads to an increase in energy costs. In this way, it is desired to shorten the deoiling time from both productivity and energy cost standpoints.

[Means for Solving the Problems] In order to solve the above problems, the inventors of the present application used a warp sizing agent containing KNO2 as a warp sizing agent used during warping in the weaving process of glass fiber fabric. We found that it is possible to solve the problem by doing this.

Furthermore, we have found that the problem can be solved by treating the original glass fiber fabric with a KNO3 solution.

〔作 用〕[For production]

内を循環する空気中と澱粉やPVA分子中に含まれる。
In the case of thermal deoiling of glass fiber fabrics, a sufficiently high temperature is required to not deteriorate the glass fibers, and sufficient oxygen is required to burn out organic sizing agents and the like. Oxygen is contained in the air circulating in the furnace and in the starch and PVA molecules.

熱エネルギーコストとの関係で限界がある。
In order to increase the efficiency of thermal deoiling, it is possible to raise the temperature or increase the amount of oxygen supplied, but raising the temperature is difficult because, as described above, the glass fibers deteriorate more rapidly. Furthermore, there is a limit to increasing the amount of oxygen in the circulating air due to the cost of thermal energy.

The KNO3 used in the present invention decomposes at about 330°C and releases oxygen gas. Therefore, this oxygen gas promotes the combustion of organic substances such as sizing agents, and is effective in shortening the heating time required for oil removal. Since the glass fiber fabric is wound into a roll and placed in a heating furnace, the inner layer of the roll tends to have insufficient contact with air, which tends to result in poor oil removal.

The glass fiber fabric of the present invention has KN attached to the fabric.
When O3 reaches high temperatures, it decomposes and releases oxygen gas, so
Even in the inner layer of the roll, the sizing agent and the like can be sufficiently burned, and the overall efficiency of oil removal can be improved. As the oxygen releasing agent, H, 0□, etc. can be used instead of KNO3.

The appropriate amount of KN (h) in the warp sizing agent is in the range of 0.601 to 1.0% in solids weight ratio to glass fiber.

If it is less than 0.01%, the effect of the present invention is difficult to appear, and if it is more than 1.0%, the effect of the warp sizing agent will be inhibited, and weavability will be reduced, which is not preferable. .

Further, when treating a raw glass fiber fabric with KNO and a solution, the amount of KNOs is desirably at least o, oi%, preferably at least 0.1%, based on the weight ratio of solids to the glass fiber fabric. If it is lower than 0.01%, the effect of the present invention will be insufficient. The textile may be treated by any method such as impregnating it in a solution, roller coating, or spraying. In this specification, the term "raw fabric" refers to a finished woven fabric to which a sizing agent or warp sizing agent is attached.

In addition, when glass fiber fabric contains KNO3, KNO3 remains on the surface of the fabric after oil removal, which adversely affects the electrical properties and water absorption when the glass fiber fabric is used for printed circuit boards or FRP. There is a concern that To deal with this, 20 can be removed by adding a water washing step in the surface treatment step after the oil removal step or by sufficiently overflowing the surface treatment tank.
