According to characteristics of fine polypropylene fiber,the technology difficulties in the spinning process of fine polypropylene fiber were described,and the spinning process of fine polypropylene fiber pure yarn was discussed.The practice was proved that through the pretreatment of fine polypropylene fiber,short spinning process were adopted,the carding machine was equipped with apron guide and active rotary guide roller device.Reasonable surface treatment of rubber-covered roll was adopted to reduce electrostatic accumulation in doubling,roving and spinning process.Air ring mutation was reduced in spinning and winding process,winding tension and speed were reduced.Through technology measures such as carding special parts,spinning process parameters and temperature&humidity conditions were reasonably arranged to solve the problems such as the difficulty of carding cotton roll into sliver,the worse spinnability caused by electrostatic accumulation in each process,and the worse yarn quality index,so as to realize successful production of the 9.84 tex fine polypropylene yarn.It is considered that fine polypropylene pure spun yarn can meet the development and application needs of clothing fabrics such as moisture absorption,quick drying and unidirectional moisture transmission.
