熱性および耐薬品性にすぐれる反面、糸自体が硬いため
に脆さがおり、靭性か不足していることから、屈曲摩耗
性ｄ３よび屈曲疲労性か劣るという欠点を有している。(Problem to be solved by the invention) However, although polyphenylene sulfide fiber has excellent heat resistance and chemical resistance, it is brittle because the yarn itself is hard, and lacks toughness, resulting in bending abrasion. It has the disadvantage of being inferior in terms of mechanical strength d3 and bending fatigue resistance.

問題が必つ ｌこ。For this reason, when trying to apply polyphenylene sulfite monofilament 1 to fabrics for papermaking canvases, there is a problem that the threads may be damaged or broken during weaving, and furthermore, they may not be bent after weaving. Since the abrasion resistance is extremely poor, for example, when used as a canvas, the bent parts of the fabric tend to break, and there is always a problem that the durability is low in this aspect.

に到達した。Therefore, the present inventors conducted extensive studies with the aim of obtaining polyphenylene sulfide monofilament, which has excellent bending abrasion resistance and bending fatigue resistance, and is particularly suitable for papermaking canvas fabric d3 and filter fabric. On the other hand, the present inventors have discovered that the above objects can be effectively achieved by using monofilaments 1 to 1 containing ionomer resins in a specific proportion.

It is desirable that the molecular weight is in the range of 200 or less, particularly 180 or less, from the viewpoint of excellent melt spinning and drawing properties and high strength of the monofilament 1 obtained.

If branched/crosslinked with a crosslinking component such as lychlorobenzene, not only the drawing property is poor and good drawing cannot be carried out, but also the knot strength of the obtained monofilament 1 is low and the MFR exceeds 200.

度なども低下するため好ましくない。The blending amount of these ionomer resins with respect to polyphenylene sulfite is 5 to 20% by weight, especially 10 to 15% by weight.
If it is less than 5% by weight, the effect of improving flexural abrasion resistance and flexural fatigue resistance is insufficient, and if it exceeds 20% by weight, not only the flexural abrasion resistance deteriorates, but also the polyphenylene This is not preferable because the tensile strength and elongation inherent to the Zarfoid monofilament are also lowered.
