摘要：

针对水龙带增强层高强涤纶管状织物与三元乙丙橡胶内衬黏结性能差的问题,采用介质阻挡放电(DBD)等离子体对高强涤纶管状织物表面进行处理,研究了处理时间对纤维表面形貌和化学组成、丝束断裂强力、织物芯吸高度及剥离强度的影响。结果表明:经DBD等离子体处理后,高强涤纶表面产生明显的刻蚀痕迹,纤维表面极性官能团增加,织物芯吸高度增加,丝束断裂强力随处理时间的延长而下降;处理时间为60 s时,强度损失率为3.9%;处理后高强涤纶管状织物与三元乙丙橡胶内衬的黏结性能得到显著改善,处理时间为60 s时,剥离强度提升35.1%。

Abstract:

In order to improve the adherent property between fire-fighting hose reinforcement layer of high strength polyester tubular fabric and an ethylene propylene diene monomer(EPDM) lining, the tubular fabrics were treated by dielectric barrier discharge(DBD) plasma. The influences of DBD plasma treatment time on the properties of fabrics such as tensile strength, fabric wicking height, surface morphology, surface chemical composition and adherent property were studied. The scanning electron microscopy images show that obvious etching marks appear in the surface of the fiber after plasma treatment. X-ray photonic spectroscopy analysis shows that the oxygen and nitrogen polar functional groups are added to the surface of fibers. The wicking height increases with the increase of treatment time. The breaking strength of the polyester tows decreases with the increase of the treatment time, and when treatment time is 60 s, the strength loss rate is 3.9%. After treatment, the peeling strength between the tubular fabric and EPDM is improved greatly, and when treatment time is 60 s, the peeling strength is increased by 35.1%.

Key words: dielectric barrier discharge, fire-fighting hose reinforcement layer, high strength polyester tubular fabric, adherent property, peel strength
