    Abstract: The present invention provides a process including: (i) dissolving, in water, a polyvinyl alcohol having a degree of saponification of 98% or more and a degree of polymerization of 800 to 3500 to prepare a polyvinyl alcohol aqueous solution in which the concentrations of methyl acetate, acetic acid and methanol are 50 ppm or less, (ii) adding the polyvinyl alcohol aqueous solution to a fibrous substrate having microfiber-generating fibers as its main constituent, so that the fibrous substrate has the polyvinyl alcohol in an amount of 0.1 to 50% by mass based on the mass of the fibers contained in the fibrous substrate, (iii) generating microfibers having an average single fiber diameter of 0.3 to 7 μm from the microfiber-generating fibers contained in the fibrous substrate as its main constituent, (iv) adding a waterborne polyurethane to the fibrous substrate comprising the microfibers as its main constituent and having the added polyvinyl alcohol, and (v) removing the polyvinyl alcohol from the fibrous substrate comprising the microfibers as its main constituent and having the added waterborne polyurethane.

    Abstract: A tufted nonwoven includes a face material which tufts a bonded nonwoven having a mixture of a plurality of bicomponent filaments 1 with a plurality of bicomponent filaments 2. At least bicomponent filaments 1 have component 11 and component 12. Component 11 exhibits a melting temperature Tm(11), and component 22 of the bicomponent filaments 2 exhibits a melting temperature Tm(22). Component 12 exhibits a melting temperature Tm(12), and component 21 of the second bicomponent filaments exhibits a melting temperature Tm(21), and Tm(12) is higher than Tm(21). The melting temperatures of components 11 and 22 and the melting temperatures of components 12 and 21 obey a relationship in which Tm(11) and Tm(22)>Tm(12)>first Tm(21) and optionally wherein the face material is bonded to bicomponent filaments 2 by a solidified melt of component 21. Also described are a bonded nonwoven and methods for their manufacture.
