<p>PURPOSE:To provide a three-dimensional structure web having an uneven surface, specific space index, specified thickness, excellent cushioning property, and excellent air permeability by binding face and back fabric tissues with plural kinds of filaments having a specific difference between their shrinkage degrees and subsequently subjecting the fabric tissues to a thermal treatment. CONSTITUTION:Face and back fabric tissues are subjected to a knitting or weaving treatment with a double raschel knitting machine or moquette loom using two kinds of monofilaments or multifilaments (the number of the filaments is relatively a few) having a difference of >=5% between their shrinkage degrees. The knit or woven fabric is heated to provide a three-dimensional structure web having an uneven surface, a thickness of 1-15mm and a space index K of 0.4-0.98 satisfied with an equation: K=1-(W/C.T) wherein W (g/m<2>) is the weight of the web; C(g/cm<3>) is the average density of the fiber raw material; and T(cm<3>/m<2>) is the volume of the web.</p> |
