- ItemDeformační vlastnosti příze ve specifických podmínkách tahového namáhání(Technická Univerzita v Liberci, 2006) Rubešová, Kateřina; Ursíny, PetrThe subject of the thesis is an experimental observation of the relationship between mass variability and deformation attributes of the yarn, especially the elongation of the yarn under a defined load pressure. The first part of the work is dedicated to a literary survey of the available findings regarding mass variability, solidity and tensibility of the yarn. It goes on with a description of a new method for continuous method of measuring, under a defined load pressure, developed by the Research institute of the textile machinery in Liberec. Then follows a description of the selected testing method, which simulates the continuous method of measuring of the elongation of the yarn employed in the experiment. The key part of the work concentrates on the realisation of the experiment. Mass variability was observed on the apparatus Uster Tester IV SX. The simulation of the continuous method of measuring of the elongation was executed on a stretching machine Lab Test 2.010.The results of the experiment are elaborated and evaluated on a mathematical and statistical basis, by means of a statistical programme QC.Expert 2.5. The conclusion summarizes the acknowledged findings resulting from the simulation method for continuous method of measuring of the relationship between mass variability and deformation attributes of the yarn, under the conditions corresponding to the new measuring process of the deformation of the yarn.
