Licker throughout carding process, remove impurities and fibers will be broken down into single fiber Virgin fiber aspect bears a significant role. Practice has proved that on the licker carding machine, able to lap 70 to 80% of the fiber bundle is decomposed into single fibers, which remove impurities and about 75%.
Adverse licker work, not only affect the work of the effects of the carding area, but also due to insufficient release and cleaning, these fiber bundles and impurities into the second carding area, thus increasing the cover and between the cylinder workload, directly affect the function of the second carding area, the impact of the bridge, network quality.
Carding and enhance the role of impurity thorn series of cowardly to do, there are two
(A) improve the speed of licker
According to the different speeds and different thorn Series production test, it was found when increasing the speed of licker, licker shift from cotton to the cylinder on the beam weight reduction percentage, carding degree increase. In the case of cotton thorn removed to move the beam weight percent on the cylinder does not increase, the relationship between the yield and the speed of the licker, when production increased by one kilogram, the licker need a corresponding increase in the speed of 125 rev / min. This relationship while accelerating or carding elbow yield large differences in the scope of the cylinder, there will be great changes.
According to practical experience, in addition to some poor single fiber strength lower cotton outside, when using plain old carding old specification flexible wire, barbed Series if selected speed 800-1000 rev / min (to consider the corresponding cylinder speed) good quality cotton net, less neps impurities, no damage to the fiber length. This is because the centrifugal force increases, the increased car belly noil rate, a significant reduction in particulate impurities in the cotton web. By the decomposition degree of improvement thorn part series fiber, reducing the workload of the cover and the second cylinder carding zone, cover flowers and flower stripper is also reduced.
Table 2-1 No. 14.58 yarn in a number of comparative information thorn series before and after acceleration. Data showed that the licker acceleration, neps and trash were decreased, but the decrease in the amplitude of neps more significant, of about 25%. Meanwhile, the very flowers cover 15% reduction in weight (cover rate constant), stripper spend decreased by 8%. These have proved, after stab Series acceleration, carding performance has improved significantly.
