  • the elongation information is given as a percentage, this refers to the test length of the fiber equal to 100%, whereby the fiber is under a titer-dependent pretensioning force (here 0.25 cN / tex). Due to the time-dependent relaxation processes in the fibers, after the tensile stress has been released and relieved, waiting times to be defined between the cycles - here: 5 minutes - must be observed before measuring the permanent strains.

Abstract

L'invention concerne des fils à base de fibres ou de filaments de mélanges polymères, comprenant comme constituants du mélange : 1) du polytérephtalate d'éthylène (PET) ou du polytérephtalate de butylène (PBT) et 2) du polytérephtalate de triméthylène (PTT) dans un rapport de mélange 1):2) d'approximativement 5:95 à 95:5, notamment d'approximativement 10:90 à 90:10. Ces fils se caractérisent en ce que les fibres ou filaments qui les forment présentent des élongations à la rupture de 15 à 35 % après un ou plusieurs processus d'étirage et, après des vérifications des fibres par cycles d'élongation, avec une élongation totale de 5 %, les fibres ou filaments présentent des élongations résiduelles permanentes ( epsilon R) inférieures à l'élongation résiduelle permanente ( epsilon R) calculée pour le premier cycle d'élongation par l'équation epsilon R [%] = 0,61 - (0,59/100) • X, pour le cinquième cycle d'élongation, par l'équation epsilon R [%] = 0,61 - (0,67/100) • X, pour le dixième cycle d'élongation, par l'équation epsilon R [%] = 0,67 - (0,65/100) • X. Dans ces équations, la variable X désigne la proportion en poids de PTT de l'ordre d'approximativement 5 à 95 % dans les mélanges de fibres ou de filaments avec du PET et du PTT ou dans les mélanges de fibres ou de filaments avec du PBT et du PTT. Les fils ne présentent pas a) de torsion, b) une torsion de fabrication avec un coefficient de torsion métrique alpha de l'ordre de 0,2 à 10 ou c) avec une torsion standard, un coefficient de torsion alpha allant jusqu'à 130. La règle standard DIN 53832 est valable pour le coefficient de torsion alpha et alpha = (t/m• 2ROOT (dtex)/100 est défini. T/m désigne le nombre de torsions par mètre et dtex, la finesse des fibres ou des filaments. L'invention concerne en outre des utilisations avantageuses de ces fils pour produire notamment des tapis, des tissus maille, des tissus, des non-tissés ou des feutres. Ces fils présentent l'avantage d'avoir aussi bien une élongation résiduelle minime après des sollicitations cycliques en élongation, que de ne pas avoir tendance à vriller ou à friser.
