Abstrakty

In this paper, we investigate the effect of texturing parameters in a false-twist draw-texturing process on the mechanical properties and the structure of polyamide yarns. A high-temperature heater was used in the study. The important effects of texturing temperature and time on the mechanical, crimp and structural parameters were studied. Detectable changes in overall crystalline orientation, crystal size and perfection of the crystals as a result of changing the texturing temperature and heater residence time were evaluated. Filament breakage rate was also investigated as a function of the D/Y ratio. An analysis of variance was carried out in order to determine the significance of the results.

Badano wpływ parametrów procesu teksturowania metodą nibyskrętu na właściwości mechaniczne i strukturę przędz poliamidowych. W badaniach zastosowano grzejnik wysokotemperaturowy i analizowano wpływ temperatury teksturowania i czasu na parametry mechaniczne przędzy, jej skręt i parametry strukturalne. Wykryto różnice w ogólnej orientacji krystalicznej, rozmiarach krystalitów i ich doskonałości jako efekt zmian temperatury teksturowania i czasu przebywania przędzy w obrębie grzejnika. Badano również ilość zrywów włókien jakofunkcję stosunku D/Y. Przeprowadzono analizę wariancji z uzyskanych wyników dla określenia ich wiarygodności.
