    摘要： In a nonwoven fiber assembly which comprises a fiber comprising a thermal adhesive fiber under moisture and in which the fiber are entangled with each other, the fibers are bonded at contacting points of the fibers by melting the thermal adhesive fiber under moisture to distribute the bonded points approximately uniformly, thereby obtaining a buffer substrate. The buffer substrate may further comprises a conjugated fiber comprising a plurality of resins which are different in thermal shrinkage and form a phase separation structure, and the conjugated fibers may have an approximately uniform crimps having an average curvature radius of 20 to 200 μm and are entangled with the fibers constituting the nonwoven fiber assembly. The buffer substrate can be obtained by a method comprising the steps of: forming a web from the fiber comprising the thermal adhesive fiber under moisture; and subjecting the obtained fiber web to a heat and moisture treatment with a high-temperature water vapor to melt the thermal adhesive fiber under moisture for bonding the fibers. The buffer substrate has a high air-permeability, an excellent cushion property and softness.
