A nonwoven fabric is formed of fibers of 0.10 μm or more and 5.00 μm or less. The nonwoven fabric includes a coarse layer portion and a dense layer portion. In the coarse layer portion, a void volume Pc is at least 90% and an average pore diameter Dc is in a range of 0.5 μm or more and 50 μm or less. In the dense layer portion, a void volume Pd is at least 70% and a relative standard deviation of pore diameter distribution is 20% or less.

This invention relates to a process and a device for manufacturing cellulose-based webs which are directly formed from lyocell spinning solution and in particular for the washing of directly formed cellulose webs.

The present disclosure is directed to a wiping product well suited to absorbing a solvent and releasing the solvent onto an adjacent surface. The wiping product can also be constructed so as to have excellent abrasion resistance. The wiping product can be used in numerous applications and is particularly well suited for wiping unfinished surfaces, such as metal surfaces and composite surfaces for removing contaminants, such as oil and grease. The wiping product is made from a hydroentangled and thermally bonded web containing staple fibers and conjugated fibers.

The invention relates to the use of a lyocell fiber (1) for the manufacture of a nonwoven fiber fleece (10, 100). To manufacture a thin nonwoven fiber fleece with sufficient mechanical properties, the use of a lyocell fiber is proposed, where the fiber (1) has a cross-sectional aspect ratio of at least 1.8.

The invention further relates to a nonwoven fiber fleece (10, 100). In order to manufacture a thin nonwoven fiber fleece (10, 100) suitable for use as a battery separator, it is proposed, that the fiber fleece comprises at least two layers (11, 12) of fibrillated lyocell fibers (13), with the fibrillated lyocell fibers (13) having solid cores (14, 110) and fibrils (15) protruding from said cores (14), the fibers and fibrils (15) being intermingled to form the fiber fleece (10), embedding the solid cores (14) therein, whereby the solid cores (14, 110) of the fibrillated lyocell fibers (13) have an average cross-sectional aspect ratio k of at least 1.5.
