この発明は、ガラス織物の耳部なほつれ止めする際その
耳部が織物地よりも耳高にならないプリント基板用ガラ
ス織物に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass fabric for printed circuit boards in which the edges of the glass fabric do not become higher than the fabric when the edges of the glass fabric are prevented from fraying.
本発明を添付図面を参照して詳述すると次の通りである

４）と略同厚になるように塗布せしめる。Shuttleless loom (: When weaving glass fabric for printed circuit boards, the warp threads (2) of the ears (1) on both sides of the fabric for printed circuit boards)
Weave a glass fabric (5) in which the selvage part (1) is thinner than the woven part (4) by using a warp thinner than the woven part warp (3) and having a higher warp density than the woven part (4). , apply an anti-fray agent (6) to this thin selvedge (1) so that the selvedge (1) is a woven fabric (
Apply it to approximately the same thickness as 4).
はつれ防止剤は、プリント基板用の樹脂含浸時に使用す
る溶剤に殆ど溶解しない、且つ含浸織物の乾燥温度にお
いて軟化しない接着剤を採用する。As the anti-tangling agent, an adhesive is used that hardly dissolves in the solvent used when impregnating the resin for printed circuit boards and does not soften at the drying temperature of the impregnated fabric.
はつれ防止剤の塗布は、上記耳部の切断前でも切断後で

厚さを織地部の厚さと実質的に同一厚さになるように樹
脂量を選択する。The anti-tangling agent may be applied before or after cutting the above-mentioned ears, and may be applied by any convenient method such as solution-type coating or hot-melt coating. ) The amount of anti-fray agent to be applied is such that the amount of anti-fray agent applied to the selvedge using thin thread is enough to exert the fray-preventing effect, and the thickness of the selvage area to which the anti-fray agent is applied is The amount of resin is selected to have a thickness that is substantially the same as the thickness of the fabric.
少し位薄くなることは許容出来るが厚くしない。I can tolerate it being a little thinner, but I don't want it to be thicker.
従来、無杼織機：二より製織したプリント基板用ガラス
織物には、例えば特開昭５２−３４０９４号に記載され
ているように織物地部と同一構成である耳部にほつれ防
止剤を塗布し、乾燥後その耳部の外端を切除してロール
巻きする方法が開示されている。Conventionally, shuttleless loom: Two-strand woven glass fabric for printed circuit boards has been coated with an anti-fray agent on the edges, which have the same structure as the woven fabric, as described in Japanese Patent Application Laid-Open No. 52-34094, for example. discloses a method of cutting off the outer end of the ear after drying and rolling it.
このような方法で製造した長尺のガラス織物をロール巻
きにすると耳部が織物地よりも肉厚の為捲回量が多くな
ればなる程耳高を生じる危険があり、耳部近くでのシワ
や織地部の緯糸の自白がりが発生し、品質の低下をもた
らす欠点があった。When a long glass fabric manufactured by this method is rolled, the selvage is thicker than the fabric, so the more the winding amount is, the higher the selvage will be. There were drawbacks such as wrinkles and weft wefts in the woven fabric, which resulted in a decline in quality.
更に、はつれ防止剤の塗布量をロール巻き時の耳高が生
じない程度に減ずれば、はつれ防止効果が不充分となり
、織物のロール巻き時やその織物に樹脂な含浸、乾燥す
る時に切断端部の経糸はつれか発生し、ロールにからま
ったり、成るいはプリプレグ中ζ二混入したりする欠点
があった。Furthermore, if the amount of anti-tangling agent applied is reduced to such an extent that no selvage occurs when the fabric is rolled, the anti-tangling effect will be insufficient, and the anti-tangling agent will be less effective when the fabric is rolled, impregnated with resin, and dried. The warp threads at the cut ends tend to become tangled, become tangled in the rolls, or get mixed into the prepreg.
また、この従来の方法で製造したガラス織物にほつれ防
止効果を充分に発揮できる量のほつれ防止剤を塗布する

（以下余白）
−を
本発明は、このような欠点を解決したもので、耳部の経
糸は織物地の経糸よりも細く、且つ経糸密度を高くする
から耳部は必ず織物地よりも薄くなる。Furthermore, if a sufficient amount of anti-fray agent is applied to the glass fabric manufactured by this conventional method to have a sufficient anti-fray effect, when the prepreg is cut to a desired length and stacked, the middle part of the prepreg will be cut due to the height of the edges. The present invention solves these drawbacks, and the warp of the selvedge is thinner than the warp of the woven fabric. In addition, since the warp density is increased, the selvage portion is always thinner than the woven fabric.
この薄くなった耳部にほつれ防止剤を塗布するから在来
のように耳部が織地部より肉厚になることが防止され、
所謂耳高による前記したような欠点が全て是正されるこ
とになり、ガラス織物をロール巻きする時、またガラス
織物を基材としてプリプレグな製造する時のいずれ（−
際しても、はつれ防止の効果を充分に発揮でき且つ耳高
による支障を発生させないプリント基板用ガラス織物と
なる。By applying an anti-fray agent to this thinned selvage, the selvage is prevented from becoming thicker than the woven fabric, as is the case with conventional methods.
All of the above-mentioned drawbacks due to the so-called selvage height will be corrected, and it will be possible to correct both when winding glass fabric into rolls and when producing prepreg using glass fabric as a base material (-
At the same time, the glass fabric for printed circuit boards can sufficiently exhibit the effect of preventing fraying and does not cause problems due to the height of the edges.
その上細い経糸が密に並べられているところにほつれ防
止剤を塗布すれば太い経糸を並べている場合よりも接電
にあずかる表面積が大きくなるからそれだけ接着が良好
となり、少ない樹脂量でも確実にほつれ止め効果が得ら
れることになる。Furthermore, if anti-fray is applied to areas where thin warp threads are closely arranged, the surface area available for electrical contact will be larger than when thick warp threads are arranged, resulting in better adhesion. This will provide a stopping effect.
この為はつれ止防止剤を塗布した部分を織地部と同厚に
することも容易となる。For this reason, it is easy to make the part coated with the anti-tangling agent the same thickness as the woven fabric part.
このように織地部と耳部とが同一厚のガラス織物を使用
してプリント基板を製造すればプリント基板は必ず平ら
な基板にあるから銅箔を重ねた場合でもその銅箔にシワ
が生じて不良品になることなどもなくなる等プリント基
板用ガラス織物として秀れた実用性を発揮する。If a printed circuit board is manufactured using a glass fabric with the same thickness for the fabric and edges, the printed circuit board will always be a flat board, so even if copper foil is layered, the copper foil will not wrinkle. It exhibits excellent practicality as a glass fabric for printed circuit boards, such as eliminating the possibility of defective products.
