いる。すなわち耐蒸熱性、耐アルカリ性（ＩＴｉ４加水
分解性）や耐摩耗性等が比較的低いと云うことである。However, as paper machines become faster, have higher dew points, and neutral paper becomes more widespread, the drawbacks of polyester resins are becoming more apparent. That is, steam resistance, alkali resistance (ITi4 hydrolysis), abrasion resistance, etc. are relatively low.

ファブリックであるが耐摩耗性にすぐれた樹脂をコーテ
ィングして芯鞘状にすることが開示されている。In order to deal with this, Japanese Utility Model Application No. 63-78098 discloses that high-performance synthetic resin monofilaments made of polyphenylene sulfide (PPS) and polyetheretherketone (PEEK) resin are applied to some or all of the warp threads of the canvas. This is used to improve heat resistance and chemical resistance. Further, Japanese Utility Model Application Publication No. 59-80498 discloses that a fabric for wet areas is coated with a resin having excellent abrasion resistance to form a core-sheath shape.

膜の厚みも薄くカンバスに適用してもはげしい屈曲摩擦
には長期の使用がむずかしかった。The method disclosed in Japanese Utility Model Application Publication No. 59-80498 uses an organic solvent, which poses environmental problems.Also, the resin coating is thin and cannot be used for long periods of time due to severe bending friction even when applied to canvas. It was difficult.
あるいはポリエステルモノフィラメントカンバスに樹脂
加工する方法はエマルジョン加工であフて被膜は非常に
薄く、長期効果は望むべくもなかった。Alternatively, the method of processing polyester monofilament canvas with resin is emulsion processing, and the coating is very thin, so long-term effects cannot be expected.
