Title
(EN) YARN COMPRISING POLYTRIMETHYLENE TEREPHTHARATE
(FR) FIL COMPRENANT DU TEREPHTALATE DE POLYTRIMETHYLENE
Abstract
(EN)
A yarn which is prepared by doubling polytrimethylene terephthalate fibers, in particular, polytrimethylene terephthalate multifilament fibers having a single yarn fiber fineness of 1 to 56 dtex, and has a total fineness of 2000 to 22000 dtex; a gut comprising a yarn which is prepared by doubling polytrimethylene terephthalate multifilament fibers having a single fiber fineness of 1 to 56 dtex and has a total fineness of 7000 to 22000 dtex; and a string for a musical instrument comprising a yarn which is prepared by doubling polytrimethylene terephthalate multifilament fibers having a single fiber fineness of 1 to 56 dtex and has a total fineness of 2000 to 14000 dtex. The yarn has high strength and a high ratio for the recovery of elasticity and the retention of stress, and is excellent in water resistance, softness and homogeneity. The gut can be stretched on a frame of a racket for tennis or the like, exhibits high rebound resilience when stretched, and retains satisfactory rebound resilience for a long period of time, and further is excellent in impact resistance, durability, and water resistance. The string for a musical instrument shows a reduced change of interval due to the elapse of time and the change of humidity and is excellent in tuning characteristics.
(FR)
On décrit un fil qui est préparé en doublant des fibres de téréphtalate de polytriméthylène, plus particulièrement des fibres multifilaments en téréphtalate de polytriméthylène ayant une finesse de fibre à un seul fil comprise entre 1 et 56 décitex et une finesse totale comprise entre 2000 et 22 000 décitex; un boyau comprenant un fil qui est préparé au moyen du doublage de fibres multifilaments en téréphtalate de polytriméthylène ayant une finesse de fibre simple comprise entre 1 et 56 décitex et une finesse totale comprise entre 7000 et 22 000 décitex, et une corde pour instrument de musique comprenant un fil qui est préparé par doublage de fibres multifilaments au téréphtalate de polytriméthylène ayant une finesse de fibre unique comprise entre 1 et 56 décitex et une finesse totale comprise entre 2000 et 14 000 décitex. Ce fil est très résistant et recouvre rapidement son élasticité, il retient bien les contraintes et présente d'excellentes propriétés de résistance à l'eau, de douceur et d'homogénéité. Le boyau peut être étiré sur un cadre de raquette de tennis ou autre, il présente une forte résilience de rebondissement lorsqu'il est étiré et conserve une résilience de rebondissement satisfaisante pendant une période prolongée, il est en outre excellent du point de vue de ses qualités de résistance aux chocs, de durabilité et de résistance à l'eau. La corde pour instrument de musique présente une modification réduite de l'intervalle dû au temps écoulé et aux variations d'humidité et possède d'excellentes caractéristiques du point de vue de l'accordage.
