Influence of cylinder speed on fiber length distribution of flat strips

Influence of cylinder speed on fiber length distribution of flat strips was studied. The flat strips were produced at four different speeds of cylinder and their lengths were tested with Premier a Qura,and the length distribution of different cylinder speeds was analyzed. The results show that fiber length distribution of flat strips is influenced by cylinder speed. The short fiber( shorter than 12 mm) content of flat strips tends to increase with the increase of cylinder speed. In view of fiber length distribution of flat strips,a cylinder speed of 450 r / min is the best,and at this speed,the fiber( less than 18 mm) the content of flat strips is higher than that of other cylinder speeds evidently. Furthermore,it may be more comprehensive and accurate to estimate carding effect by using of fiber length distribution in comparison with using fiber length parameters.
