Provided is a water absorbent laminate including: a first fiber layer including a first fiber assembly including first hydrophilic fibers; and a second fiber layer including a second fiber assembly including wet-heat-adhesive fibers in an amount greater than or equal to 80% by mass, wherein a surface of the first fiber layer on a side opposite to the second fiber layer has a water absorption rate less than or equal to 10 seconds as determined in accordance with the dropping method defined in JIS L 1907. Also provided is a method for producing the water absorbent laminate. The water absorbent laminate can further include a third fiber layer including a third fiber assembly including second hydrophilic fibers between the first fiber layer and the second fiber layer.

Nonwoven fabrics may be fashioned as topical delivery systems with increased and controllable rate of product release, while still possessing the requisite strength and durability for mass production and distribution. Such delivery systems comprise fabrics that are fashioned from micro-denier fibers that are produced by fibrillating bicomponent island-in-the-sea fibers. Facial masks made from these fabrics can achieve adequate product delivery in 3-5 minutes or less.

A composite nonwoven sheet material includes pulp fibers, a reinforcement material and microfibers. The sheet material has one pulp-enriched first outer layer and one microfiber-enriched second outer layer, the reinforcement material is thereby interposed between the pulp-enriched first outer layer and the microfiber-enriched second outer layer and the pulp fibers and the microfibers penetrate the reinforcement material. Also disclosed is a process of producing such composite nonwoven sheet material and the use of such composite nonwoven sheet material.

Provided is a porous laminate having satisfactory resistance to a mechanical load such as a bending stress while maintaining the characteristics of a porous structure. A porous laminate includes: a layer A formed on a support, the layer A including a porous film containing polymer nanofibers; and a layer B formed on the layer A, the layer B including a porous film containing polymer nanofibers, in which: an existence ratio of the polymer nanofibers contained in the layer A) is larger than an existence ratio of the polymer nanofibers contained in the layer B; and a difference between the existence ratio of the polymer nanofibers contained in the layer A and the existence ratio of the polymer nanofibers contained in the layer B is more than 40%.

A self-bonded nonwoven web, at least some cellulosic fibers that are self-bonded to each other at points of intersection of the cellulosic fibers with each other; and, an ionic liquid. Methods of making such a web are also disclosed, wherein the method comprises: contacting at least some of the first, cellulosic fibers with an ionic liquid; exposing the ionic liquid and the first, cellulosic fibers to a first temperature; and exposing the ionic liquid and the first, cellulosic fibers to a second temperature that is lower than the first temperature.

A meltblown method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse prepared bio-polyamide 6,10 into a melt, then extrude, and blow the melt out spinnerets to form natural bio-polyamide 6,10 filaments laid onto a conveyer to form a substrate fibrous web. Secondly, blend and dissolve prepared pulp by putting N-methylmorpholine N-oxide (NMMO) dissolving solvent, and dehydrate it to form dope, then extrude and blow the dope out spinnerets to form natural cellulose filaments laid up over existing fibrous web of bio-polyamide 6,10 on the conveyer so that a fibrous composite of the bio-polyamide 6,10 and natural cellulose in overlaid lamination is formed thereon. Finally, coagulate and regenerate the fibrous composite of the bio-polyamide 6,10 and natural cellulose by means of ejecting mist aerosol of water, and convert it into nonwoven fabric with hygroscopic metastatic feature by orderly applying post treatments of hydro-entangled needle punching, drying, winding-up processes.
