中文摘要: |
介绍了芳纶纤维的性能及其浸渍帘布的捻织和浸渍工艺,并分析了影响芳纶帘线断裂强度保持率的因素。芳纶纤维具有高模量、高断裂强度、低热收缩率和低断裂伸长率,是轮胎的理想骨架材料;通过采用不同的复捻与初捻比、初捻和复捻速度分别为4 000和5 000 r·min -1及选用光环气圈环等措施可使芳纶帘线的断裂强度保持率由60.4%提高到81.2%;在芳纶生产中采用“双浴法”浸渍工艺、以封闭TDI为浸渍液、控制浸渍过程中的热处理时间和温度可保证芳纶浸渍帘线良好的性能。 |
英文摘要: |
The properties of aramid yarn and the twisting,weaving and dipping technology of dipped aramid cord were investigated and the effective factors on the rupture strength retention of aramid cord were analysed. The results showed that the aramid cord was an ideal reinforcing material for tire because of its high modulus and rupture strength,low thermal shrinkage and elongation at break;the rupture strength retention of aramid cord was increased from 60.4% to 81.2% by using different double twist/initial twist ratio,initial twisting speed of 4 000 r·min - 1 and double twisting speed of 5 000 r·min - 1,and a smooth ring in twisting device;and an aramid cord with good performance was obtained by using the double bath dipping process and the blocked TDI as dipping compound,and controlling the time and temperature of thermal treatment during dipping. |
