Abstract
In a polyester multi-filament yarn consisting of at least two kinds of false twisted filament yarns having different sectional shapes, the present invention relates to a combined and multi-component false twisted filament yarn which comprises at least one kind of filament yarns having a specific sectional shape not having a recess and the other kind of filament yarns having a specific sectional shape having recesses, and wherein the filament yarns having the respective sectional shapes are dispersedly mix-woven. The present invention relates also to a method of producing such a combined and multi-component false twisted multi-filament yarn and a knitted/woven fabric obtained by using such a yarn. The present invention can provide a combined and multi-component false twisted filament yarn capable of providing a knitted or woven fabric having an excellent drape property and high dry feeling by additional twist within a lower range than the number of twists imparted conventionally to false twisted yarns, also having a puff property, soft feeling and mild, dry and slippery and pliable feeling which are different from hard and hard and sandy feeling obtained conventionally by hard twist…
