摘要： An extruded monofilament is formed from a compatibilized blend of polyphenylene sulfide and a polyamide resin. The blend is compatibilized by the addition of a compatibilizing resin selected from the group consisting of chemically modified and functionalized polyolefins. Preferably, from about 25 to about 99 parts by weight of a polyphenylene sulfide resin and from about 75 to 1 parts by weight of at least one polyamide resin, together with from about 0.1 to 10 parts by weight of a compatibilizer are blended and extruded to form the monofilament. The resultant monofilament exhibits improved physical properties as compared to unblended polyphenylene sulfide resins (PPS), as well as uncompatibilized blends of PPS with other materials. The monofilaments prepared from these compatibilized blends are useful as components of industrial fabrics, particularly fabrics such as are used as belts on paper forming machines. The polymer blend and a process for the manufacture of the monofilaments are also provided.

摘要： A monofilament which exhibits improved hydrolytic stability properties as compared to conventional polyester monofilaments is formed from the extrusion of a blend of PPS and at least one polymer selected from the group consisting of PET, a high temperature polyester resin and polyphenylene oxide and possibly, a hydrolytic stabilizing agent. The monofilament is produced without the inclusion of compatibilizers or fillers, even though PPS is known to be incompatible with PET and high temperature polyester resins in most applications. A fabric may be produced having increased resistance to hydrolytic degradation and includes a plurality of woven monofilaments, comprising a blend of PPS with at least one other polymer selected from the group consisting of PET, a high temperature polyester resin and polyphenylene oxide and, a hydrolytic stabilizing agent. Such fabrics have utility as fabrics for the dryer sections of paper machines. Methods for the production of such monofilaments are also provided.

摘要翻译：与常规聚酯单丝相比，显示改善的水解稳定性的单丝由PPS和至少一种选自PET，高温聚酯树脂和聚苯醚的聚合物的共混物的挤出形成，并且可能的是水解稳定剂。尽管在大多数应用中已知PPS与PET和高温聚酯树脂不相容，但单丝也不包含增容剂或填料而生产。可以生产具有增加的抗水解降解性的织物，并且包括多个编织单丝，其包含PPS与至少一种选自PET，高温聚酯树脂和聚苯醚的其它聚合物的共混物，以及水解稳定剂。这种织物具有用作造纸机烘干机部分的织物的作用。还提供了生产这种单丝的方法。
