CA 2576775

A composite fiber, which, when crimps are developed, causes a reversibly varied percentage crimping upon exposure to moisture, and can maintain the above excellent percentage crimp change properties even after steps such as dyeing, finishing and the like, has excellent practicability, and can easily provide a comfortable woven fabric which can control stuffiness. The composite fiber comprises a polyester component and a polyamide component which have been bonded to each other in a side-by-side form or an eccentric core-sheath form. This composite fiber is treated with boiling water under a load of 1.76 ~ 10-3 cN/dtex for 30 min and is further subjected to dry heat treatment under a load of 1.76 ~ 10-3 cN/dtex at 100~C for 30 min for stabilization of the crimp. The fiber after the dry heat treatment at 160~C for one min under a load of 1.76 ~ 10-3 cN/dtex, the percentage crimp DC is 1.3% to 15.0%, the percentage crimp HC after immersion in water at 20 to 30~C for 10 hr is 0.5 to 10%, and the percentage crimp difference .DELTA.C is 0.5 to 7.0%.

L~invention porte sur une fibre composite, qui, en présence de frisures, provoque un effet de frisure à pourcentage variant de façon réversible en cas d~exposition à l~humidité et peut conserver les excellentes propriétés ci-dessus en matière de changement de frisure proportionnelle même après des phases de teinture, de finition et autre, très pratique et permettant d~obtenir un tissu tissé confortable maîtrisant la capacité de bourrage. La fibre composite comprend une composante de polyester et une composante de polyamide collées l~une à l~autre par formation côte à côte ou de type gaine/noyau excentrique. Cette fibre composite est traitée à l~eau bouillante à une contrainte de 1,76 × 10-3 cN/dtex pendant 30 minutes puis est soumise à un traitement thermique sec à une contrainte de 1,76 × 10-3 cN/dtex à 100°C pendant 30 minutes pour stabilisation de la frisure. La fibre subit ensuite un traitement thermique sec à 160°C pendant une minute à une contrainte de 1,76 × 10-3 cN/dtex, après quoi la frisure proportionnelle DC est comprise entre 1,3% et 15,0%, la frisure proportionnelle HC après immersion dans l~eau à une température de 20 à 30°C pendant 10 heures est comprise entre 0,5 et 10%, et la différence de frisure proportionnelle .DELTA.C est comprise entre 0,5 et 7,0%.
