A process for the production of a nonwoven fabric. In particular, it relates to the production of a nonwoven fabric having desirable tactile and haptic as well as mechanical properties, as well as to the nonwoven fabric itself. The process requires the selection of specific polylactic acid polymers and corresponding process conditions.

A fiberball includes: a core region; and a shell region. A fiber density in the core region is higher than a fiber density in the shell region. At least 50% by weight of fibers contained in the fiberball, based on a total weight of the fibers contained in the fiberball, have a length of at least 60 mm.

A fiber aggregation contains fiber containing a thermoplastic resin, each of the fiber being mutually joined and aligned.

Provided is a palp 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.

A method for the production of a continuous nonwoven fabric from fiber mixtures of carrier fibers and binding fibers, comprising the steps: a. Feeding fibers; b. Breaking up, combing and opening out the fibers; c. Mixing the fibers; d. Sucking the fibers between two opposing airpermeable conveyor belts running at identical speed, such that the air is sucked from the outside in the front section of the conveyor belts in such a way that the air flow is always sucked through the deposited nonwoven fabric by air extraction at different times and different locations across the width and parallel to the conveyor belts and the fibers are thereby positioned perpendicular to the surface of the conveyor belts; e. Thermally solidifying the nonwoven fabric created by heating with hot air or shortwave radiation and cooling. Also a nonwoven fabric production apparatus.

A pouched product adapted for release of a water-soluble component therefrom is provided herein. The pouched product can include an outer water-permeable pouch defining a cavity containing a composition that includes a water-soluble component capable of being released through the water-permeable pouch and has a surface area, wherein the outer water-permeable pouch can include a nonwoven web including a plurality of heat sealable binder fibers blended with a second plurality of dissimilar fibers. The nonwoven web can be carded, hydroentangled and point bonded.

There is provided a fiber molded body for sound absorbing/sound insulation materials, which is lightweight and has excellent sound absorption performance. The fiber molded body for sound absorbing/sound insulation materials of the present invention is a fiber molded body for sound absorbing/sound insulation materials comprising uncolored ultrafine chemical fibers and colored fibers or reclaimed fibers, wherein the single fiber fineness of the ultrafine chemical fibers is 0.01 to 0.5 dtex, the content of the ultrafine chemical fibers is 5 to 70 mass % and the content of the colored fibers or the reclaimed fibers is 20 to 60 mass %, in the fiber molded body for sound absorbing/sound insulation materials.

The invention relates to a filtration unit for the leucocytapheresis of the blood or of a blood product. The filtration unit has an external pouch with at least one inlet orifice and with at least one outlet orifice. the external pouch contains a porous element interposed between the orifices. he porous element has at least one leucocytapheresis medium that works by adsorbing and/or by filtering out the leucocytes, and at least one nonwoven layer provided with bumps, each of the bumps having a perforation passing through it in the heightwise direction.
