677.21:021.164 INVESTIGATION OF THE INFLUENCE OF SPEED MODES OF THE COMBINED DRUM ON THE QUALITY INDICATORS OF THE TAPE

Abstract

Abstract:

Objective. In this research work, using the system of modern technological equipment, the effect of the parameters of the main working organs of the combed machine on the quality indicators and fiber length of the wick obtained from the selection of medium fiber cotton was studied. It was determined that the staple length of the fiber increased by 2.07 mm at a speed of 350 min^-1. The purpose of the study is to study the influence of the comb speed of the combed drum on the quality parameters of the sliver and the staple length of the fiber.

Results: In the experiment, the influence of the speed of rotation of the comb drum on the quality parameters of the combed sliver was studied. As a result, when the rotation speed of the combed drum is 350 min^-1, the coefficient of variation of the combed sliver is improved, the staple length of the fiber is increased by 2.07 mm.

Conclusion:

The distribution of the mass of fibers over the cross section of the tape tape corresponds to the normal distribution law Cm/Um=1.25 (2.72/2.32). Unevenness of the combed sliver in 1 m segments decreases with a decrease in the speed of the combed drum, and with an increase in its speed it increases by 12%. The clogging of the batt decreases with an increase in the speed of the drum, in which the number of defects per 1g of tape is 26 i.e. the minimum value of the compared options.
