Abstract
In order to improve the quality of sliver made from fine denier fibers, a pin drafting method was investigated. Especially, the study of fiber control in drafting zone, pin count and pitch between moving gill-faller bars was discussed in this paper. The experimental result showed that the pin count of 24 provided higher quality slivers than that of 18. In addition, the sliver quality was also changed with the pitch between moving gill-faller bars. The relationship between the mean fiber length in the sliver and the total distance of the front nip gauge as well as the faller pitch is the most important in the control of fibers during drafting, thus the quality of the drafted sliver can be improved by adjustment of the relationship.
