Title
(EN) SPUN YARN COMPRISING POLYESTER STAPLE FIBRE AND FABRIC COMPRISING THE SAME
(FR) FILÉ COMPRENANT UNE FIBRE DISCONTINUE DE POLYESTER ET TISSU LE COMPRENANT
Abstract
(EN)
Disclosed herein are spun yarns comprising melt spun staple fiber comprising a first polymer and a second polymer, wherein the first polymer comprises poly(trimethylene terephthalate) or poly(butylene terephthalate) and the second polymer comprises poly(ethylene terephthalate) or Co-PET, wherein Co-PET is a poly(ethylene terephthalate) copolymer comprising isophthalic acid monomer; and wherein the first polymer comprises poly(trimethylene terephthalate) and the weight ratio of the poly(trimethylene terephthalate) to the second polymer is in the range of from about 80:20 to about 10:90; or the the first polymer comprises poly(butylene terephthalate) and the weight ratio of the poly(butylene terephthalate) to the second polymer is in the range of about 90:10 to about 10:90. The spun yarn may further comprise a second staple fiber such as cotton or wool. The spun yarn is useful in preparing fabrics having advantageous properties.

L'invention concerne des filés comprenant une fibre discontinue filée à l'état fondu comprenant un premier polymère et un second polymère, le premier polymère comprenant du poly(triméthylène téréphtalate) ou du poly(téréphtalate de butylène)) et le second polymère comprenant du poly(téréphtalate d'éthylène) ou du Co-PET, le Co-PET étant un copolymère de poly(téréphtalate d'éthylène) comprenant un monomère d'acide isophtalique ; et le premier polymère comprenant du poly(triméthylène téréphtalate)) et le rapport en poids du poly(triméthylène téréphtalate) au second polymère étant situé dans la plage d'environ 80:20 à environ 10:90 ; ou le premier polymère comprenant du poly(téréphtalate de butylène)) et le rapport en poids du poly(téréphtalate de butylène) au second polymère étant situé dans la plage d'environ 90:10 à environ 10:90. Le filé peut en outre comprendre une seconde fibre discontinue telle que du coton ou de la laine. Le filé est utile dans la préparation de tissus ayant des propriétés avantageuses.
