Abstract
Effect of carding machine using gill pin taker-in on polyester yarn hairiness was studied. The hairiness of the yarn processed by carding machine with gill pin taker-in and saw-tooth taker-in respectively, which using three-grade speed was tested by YG172 Yarn Hairiness Tester. The results show that (1) when using gill pin taker-in, it is most advantageous to the reduction of hairiness of 2 mm and above when the taker-in speed is 1290 r/min, while it is most advantageous to the reduction of hairiness of 3 mm and above when the taker-in speed is 820 r/min; (2) when using saw-tooth taker-in, it is most advantageous to the reduction of yarn hairiness when the taker-in speed is 1290 r/min; (3) the hairiness of the yarn processed by gill pin taker-in is more than that processed by saw-tooth taker-in as a whole.
