Abstract
A fiber bundle is provided that strikes an excellent balance among the properties and performance of the web and articles manufactured using this web, the productivity, proccessability, and cost. The fiber bundle comprising continuous fibers aligned in one direction is characterized in that the continuous fibers have crimps that form peaks and valleys in the width direction of the fiber bundle, and these crimps have a characteristic value A, defined as the absolute value of a slope with respect to the length direction of the fiber bundle of a straight line that connects the vertex of the peak with the vertex of the valley of adjacent crimps present in a single continuous fiber, of at least 0.3.
