ABSTRACT:
A bulky and reinforced non-woven fabric and a process for producing the fabric are provided, which fabric is composed of a web consisting of 30-100% by weight of hot-melt-adhesive fibers and 70-0% by weight of fibers having a m.p. higher than that of the hot-melt-adhesive component of the hot-melt-adhesive fibers and monofilaments, fibers constituting the web being adhered onto one another and also to the monofilaments and the fabric having wrinkles at a wavelength of 0.1 to 20 mm over the whole surface of the fabric; and which process comprises arranging monofilaments of a percentage of shrinkage of 20% or higher under heat treatment conditions for melt-adhering the hot-melt-adhesive fibers over the whole surface of the web; adhering the fibers constituting the web onto one another and also to the monofilaments through hot-melt-adhesion; and also causing the web to shrink through shrinkage generated in the monofilaments.
