| Polyphenylene Sulfide(PPS) is a new and special engineering material which has a lot of excellent properties such as: high temperature resistant(resisting quality) and concentrated base resistant. It has been one of the most popular special engineering materials in the world and will have a bright future. But PPS has its own defects, for example the bad property of hydrophilic. So in this paper we focus on the research of modification of hydrophilic property of PPS non-woven.First, we modified the hydrophilic property of PPS non-woven by using sulphonation. Contact angle, SEM, EDX, the Electronically Strength Analysis Apparatus of Fabric and the property of concentrated base resistant testing have been used to characterize the properties of the sulphonated PPS and the effect of time, temperature and the ratio of reactants on the hydrophilic property of PPS are illustrated in detail. The results show that contact angle of PPS has decrease (reduced)a lot after sulphonating, not only the hydrophilic property of PPS has been improved obviously but also it has good timeliness by this way and the optimal reactive conditions of sulphonating is: reactive temperature: 80°C; reactive time: l~1.5hour.Second, we used RF(Radio frequence)air plasma treatment to modify the hydrophilic property of PPS non-woven. The influences of plasma parameters such as treatment power and treatment time on the hydrophilic property of PPS non-woven were discuss in details by analysis of contact angle, SEM, the electronically strength analysis apparatus of fabric and the property of concentrated base resistant testing. The results show that the contact angle of PPS has decrease (reduced) a lot and the hydrophilic property of PPS has been improved evidently by air plasma treatment, and we concluded that the optimal reactive conditions of plasma treatment is: treatment power: 50W; treatment time: 90 seconds.At last, we also try to initiate graft copolymerization of hydrophilic monomer onto surface of PPS non-woven after plasma treatment so as to further improve the timeliness of the hydrophilic property of PPS, but the result was not satisfying for we haven't found the suitable graft condition. Therefore, it is important and necessary to further explore the optimal graft condition in the future. |
