Abstract
A high-strength ultra-fine fiber construction including a high-strength multi-filament yarn including ultra-fine filaments of a fineness of a single filament less than 0.8 denier, a tenacity of 6.5 g/d or more, and the elongation at break of the multi-filament yarn being 15% or more. In order to obtain such a fiber construction, islands-in-sea-type or divisional type conjugate spinning is initially carried out to obtain conjugate multi-filament yarns, which is subjected to weaving to produce a fabric, and a island component removing or dividing treatment is finally done in order to obtain the high-strength ultra-fine fiber in the fiber structure. Ultra-fine fibers of the desired strength together with a particular range of a cover factor provides all the advantages of the ultra-fine fibers. A reduced air permeability, when it is necessary, can be easily obtained. Namely, a desired mechanical property as well as a desired softness are both obtained, while the number of naps and filament breakages are reduced. An air bag as the fiber construction can attain any desired properties such as high mechanical strength, a large degree of softness, a neatness when folded, and a low air perme…
