Nonwoven webs/nonwoven laminates for use in absorbent articles are disclosed. The nonwoven laminate includes a first nonwoven web with continuous spunbond crimped fibers and a second web joined to the first nonwoven web. A plurality of apertures extend through at least one of the first nonwoven web or the second web. The nonwoven web includes a plurality of continuous spunbond crimped fibers wherein a plurality of apertures extend through the nonwoven web.

A device and method for excellent recovery of bulk in nonwoven fabric. While nonwoven fabric is transported so as to enter a heating chamber via an entry opening and, after progressing within the heating chamber, exit the heating chamber via an exit opening, heated air is supplied at a speed higher than the transport speed for the unwoven fabric so as to enter the heating chamber via the entry opening and after progressing within the heating chamber while contacting the nonwoven fabric, exit the heating chamber via the exit opening.

Provided is a pulp fibrous accumulated sheet including: a liquid permeable pulp fibrous accumulated layer containing a crushed pulp or base-fibers mainly including a crushed pulp, and a binder, and a plurality of fiber crimped parts formed by compression and pressurization, the fiber crimped parts being formed so that crushed pulp fibers each straddling the adjacent fiber crimped parts are present.

The invention relates to a process for producing a mineral fiber mat. The mineral fiber mat comprises a mineral fiber component A comprising minerals fibers selected from stone fibers, glass fibers, and mixtures thereof, and a cured binder component B. Cured binder component B is prepared by curing, at a temperature in a range of from 80 to 250 C., of a binder mixture comprising as binder constituents c1) one or more amino acid polymers having two or more primary amino groups and c2) one or more alpha-hydroxy carbonyl compounds. The invention further relates to the mineral fiber mat and a mineral fiber composite mat. The mats of the invention are used as or in a construction product, or in a transportation vehicle.
