Title (EN) PARALLEL COMPOSITE FIBRE
(FR) FIBRE COMPOSITE PARALLÈLE
(ZH) 一种并列型复合纤维
Abstract: front page image
(EN) Disclosed is a parallel composite fibre, prepared by parallel composite spinning and then false twisting processing of polybutylene terephthalate with an intrinsic viscosity of 1.00-2.00 dl/g and a polyester with an intrinsic viscosity of 0.45-0.65 dl/g in a weight ratio of 70:30 - 30:70, wherein the difference between the intrinsic viscosity of polybutylene terephthalate and the polyester is 0.35-1.55 dl/g, the elastic elongation of the fibre is 20%-129%, and the elastic recovery rate of the fibre is 65% or more.
(FR) L'invention concerne une fibre composite parallèle, préparée par traitement par filage composite parallèle, puis par traitement par fausse torsion de polybutylène téréphtalate, dont la viscosité intrinsèque est comprise entre 1,00 et 2,00 dl/g, et d’un polyester, dont la viscosité intrinsèque est comprise entre 0,45 et 0,65 dl/g, selon un rapport pondéral de 70:30 à 30:70, la différence entre la viscosité intrinsèque du polybutylène téréphtalate et celle du polyester étant de 0,35 à 1,55 dl/g, l'allongement élastique de la fibre étant de 20 % à 129 %, et le taux de récupération élastique de la fibre étant supérieur ou égal à 65 %.
(ZH) 本发明公开了一种并列型复合纤维,该纤维由特性粘度为1.00~2.00dl/g的聚对苯二甲酸丁二醇酯与特性粘度为0.45~0.65dl/g的聚酯以70∶30~30:70的重量比进行并列复合纺丝后经假捻加工制得,其中,聚对苯二甲酸丁二醇酯与聚酯的特性粘度差为0.35~1.55dl/g,并且该纤维的弹性伸长率为20~129%,弹性回复率在65%以上。
