 Full text | Abstract: The tensile strength of cotton sliver was analysed under dynamic conditions with the use of an F460 Stick-Slip Friction Tester apparatus from the Zweigle company. In order to obtain measuring data, the fibre stream is directed through the drawing apparatus at constant velocity and constant drawing ratio. Changes in the force created as a result of drawing the fibre stream were continuously recorded with the use of a measuring gauge placed between the pair of drawing rollers. For the purpose of this investigation, the tests were carried out after the second drawing zone for a sliver of central-Asiatic cotton with linear density of 3.4 ktex. |
