More specifically, the present invention relates to a glass fabric in which the thickness of the sealing resin coated portion is thinner than the thickness of the ground thread portion.

いた。(Prior art) When a glass fabric woven by a fragmentary loom is impregnated with a resin liquid and processed with resin to make blobs for electrical insulation, for example, the weft of the free end threads of the glass fabric is in a state where the glass filaments easily separate. Therefore, the glass filament is bent and cut, mixed into the resin liquid bath, and the cut glass filament adheres to the bristles after resin processing, impairing the smoothness of the brittle rug surface. For this reason, glass fabrics woven by fragment looms have been limited in use for electrically insulating blip rugs. In order to solve this problem, the area coated with sealing resin is usually cut off using a laser beam or a physical cutting method to cut the area coated with sealing resin at the base thread inside the free end yarn part of the glass fabric. Methods have been used to prevent filaments from entering the resin liquid tank.

。However, in this case, since the sealing resin is applied to the ground thread part, a sealing resin layer is formed on the ground thread part, and the thickness of the edge of the glass fabric at the cut part is approximately 5.5
It becomes thicker by ~8%, and as a result, when the glass fabric is rolled, the area coated with sealing resin becomes bulky, causing wrinkles on the surface of the rolled glass fabric, and stacking of the resin-treated rugs. Sometimes it gets deformed due to the difference in thickness.

The purpose of the present invention is to propose a glass fabric that can improve the efficiency and quality of brippure rug production by making the thickness of the filler resin coated part of the glass fabric woven by a fragmentary loom thinner than the ground yarn part.

９５％以下であることが望ましい。When considering electrical insulation, which is the main use of glass fabrics, thickness uniformity is the most important issue. The most commonly used glass fabric thickness in this case is 180 microns. The thickness is generally measured by the test method of JIS R34165.4. The thickness of the sealing resin coated part of the glass fabric according to the present invention must be thinner than the thickness of the ground thread part before application, and the relationship between the sealing resin coating layer and the thickness of the sealing resin part is It is desirable that the sum of the thicknesses of the glass fabric layers in the area coated with sealing resin is thinner than the thickness of the ground thread part, and in the present invention, the total thickness of the area coated with sealing resin is 95% or less of the thickness of the ground thread part. It is desirable that

囲で目止め樹脂の塗布工程で支障をきたさなければいく
ら薄くても差支えない。The reason for this is that the thickness of the sealing resin coating layer is in the range of 10 to 15 microns, which is 5.5 to 8.3 microns thicker than the base thread.
%, and the thickness of the resin-coated portion of the glass fabric may be 95% or less of the thickness of the ground yarn portion. More desirably, the thickness is 90% or less of the thickness of the ground thread portion, taking into account variations in the sealing resin coating layer. Regarding the minimum thickness of the woven fabric portion of the sealing resin coating layer, it may be as thin as it can be as long as it can be woven and does not interfere with the coating process of the sealing resin.

のいずれの方法によっても目的は達成可能である。In such a structure, the thickness of the glass fabric can be reduced only in the area where the sealing resin is applied. Change the cutting order and partially reduce the warp density <'A
This can be achieved by a method of weaving or by a method of weaving with a fine warp thread count while keeping the uniform reed density.In the present invention,
The objective can be achieved by either method.
