Abstract
A fabric comprising an aggregation of a plurality of bundles of superfine filaments, each such bundle being obtained by separating multi-component composite filaments is provided. Each such bundle has at least two different kinds of superfine filaments, one such kind of superfine filament being dispersed without maldistribution in the bundle. The respective kinds of superfine filaments have a difference in coefficient of free contraction of at least 5%, or one kind of superfine filament is a single component filament and the other kind of superfine filament is a bicomponent type filament. Also provided is a method of making a bundle of puffy superfine filaments.
