Abstract:In order to solve the problems in the development of yarn and fabric of high strength aramid staple fiber，taking high strength para-aramid staple fiber as the main raw material，the effects of three different carding methods and carding processes of blowing-carding unit carding，roving instrument carding after blowing-carding unit carding，roving instrument carding on yarn forming properties of fibers are compared.On this basis，the spinning process design of high strength aramid fiber/conductive fiber 98/2 blended ring spining yarn is completed by trial spinning，and the yarn that can be used for weaving high performance protective clothing is obtained.The results show that the carding process is a critical step to determine the quality of aramid yarn.Compared with the traditional type of cotton carding unit，rotor roving instrument carding can help to reduce neps，and improve fiber straight parallel degree，to make the fiber card more fully；it is simple in operation，controllable in process，low requirement to the raw materials，small in waste，so it is more suitable for high performance fiber yarn spinning and R&D.
Key Words:high strength para-aramid；carding method；conductive fiber；blowing-carding unit；roving instrument；rotor；carding roller
