Abstract
Effect of web cleaner on front plate suction form of carding machine on the quality of card sliver was studied. The card slivers processed by carding machine with web cleaner installed on the front plate using single and double sides suction forms were tested by Premier aQura. The results show that, when the suction volume is between 120~240m3/h, the range of short fiber content in card sliver is 12.03~14.0% in the single side suction and is 15.6~16.8% in the double sides suction; 5% length of fiber in card sliver is between 34.03~34.04mm in the single side suction and is between 33.64~33.83mm in the double sides suction; effective length of fiber in card sliver is from 29.71mm to 29.80mm in the single side suction and is from 29.52mm to 29.55mm in the double sides suction; total neps in card sliver is between 51~55cnt/g in the single side suction and is between 57~59cnt/g in the double sides suction. Thus it can be seen that under the same suction volume, the front web cleaner with single side suction is more beneficial to improving the quality of card sliver, so it is better for the front web cleaner to use single side suction form.
