现在输送带的承重能力越来越大，输送距离越来越远，要求输送带具有高强度和轻型化特征。目前，我国织物芯分层输送带的发展主要是普通织物芯分层输送带向高强度少层化方向发展，煤矿井下用阻燃输送带在井下使用时既要达到阻燃的目的也要向轻型化、节能、环保方面发展。而芳纶作为目前发展起来的高性能纤维有着优良的性能，如，不易自燃、离火自熄、强力高、重量轻、运行能耗大幅降低、成槽性好及耐热与耐腐蚀性优异。
Now the carrying capacity of the conveyor belt is getting larger and larger, and the conveyor distance is getting farther and farther. At present, the development of the layered conveyor belt with fabric core in our country is mainly from the layered conveyor belt with ordinary fabric core to the high strength and less layered conveyor belt. Aramid fiber as a high-performance fiber has excellent properties, such as, not easy to spontaneous combustion, self-extinguishing from fire, high strength, light weight, greatly reduced operating energy consumption, good grooving and excellent heat resistance and corrosion resistance.
