摘要： There is provided a fiber bundle that strikes an excellent balance between the properties and performance of the resulting web and the finished products obtained from this web, and cost, ease of work, and productivity. There is also provided a method for manufacturing a web using this fiber bundle. There is also provided a web that is uniform and has excellent soft touch and bulkiness. This is achieved by a fiber bundle with a total denier of 10,000 to 500,000 dtex, obtained by bundling thermoplastic, conjugate, continuous fibers that have a single filament denier of 0.5 to 100 dtex/f and in which the center of gravity of conjugate components varies among the conjugate components in a fiber cross section, wherein the thermoplastic, conjugate, continuous fibers that make up the fiber bundle have a spontaneous crimp of 8 to 30 crimps per 2.54 cm, the fiber bundle density as defined by D1/(W1 L L1) (where D1 is the total denier, W1 is the fiber bundle width, and L1 is the fiber bundle thickness) is 100 to 2000 dtex/mm2, and the density ratio by spreading (the web density/fiber bundle density after spreading by drawing to a ratio of 1.6 in a pinch roller spreading machine at a rate of 25 m/min and a fiber bundle temperature of 25 ) is 0.10 or less.
