芳纶浸渍帘布捻浸生产工艺
摘要：
芳纶浸渍帘布捻浸生产工艺，属于工业用布技术领域。将芳纶工业丝依次进行初捻、复捻、织布、第一浴预处理、干燥处理，然后在进行热牵伸、二浴浸渍、热定型，最后进行冷却松弛，制得芳纶浸渍帘布；所述第一浴预处理中的预浸液的配方为：封闭异氰酸酯、环氧树脂、黄蓍树脂、软水；所述二浴浸渍的配方为：丁吡乳胶干重、RF树脂、软水、氨水；所述RF树脂的配方为：间苯二酚、甲醛、氢氧化钠、软水。本发明具有抗高温、抗酸碱、高耐磨的优点，提升了浸胶液的性能。
摘要（英）：

The invention discloses an aramid fiber impregnated cord fabric twisting and dipping method and belongs to the technical field of industrial fabrics. The method comprises orderly carrying out primarytwisting, re-twisting, weaving, first bath pretreatment and drying on industrial aramid fibers, carrying out hot stretching and second bath impregnation, carrying out heat setting and carrying out cooling relaxation to obtain an aramid fiber impregnated cord fabric. A pre-impregnation solution used in the first bath pretreatment comprises blocked isocyanate, epoxy resin, radix astragali resin andsoft water. A formula used in the second bath impregnation comprises butadiene vinyl-pyridine rubber latex (based on dry weight), RF resin, soft water and ammonium hydroxide. A formula of the RF resincomprises resorcinol, formaldehyde, sodium hydroxide and soft water. The aramid fiber impregnated cord fabric has the advantages of high temperature resistance, acid and base resistance and high wearresistance and improves the performances of the rubber dipping liquid.
