Microfiber-containing nonwoven fabrics

Nonwoven fabrics including (i) continuous fibers and (ii) a blend of staple fibers comprising polyester staple fibers, bicomponent staple fibers, microfiber staple fibers, and wettable staple fibers, in which the continuous fibers are mechanically entangled with the blend of staple fibers. The continuous fibers and the blend of staple fibers may be mechanically entangled via a hydroentangling process.

Wiping Products Made from Foam Formed Webs

A process for foam forming webs is disclosed. The foam formed webs can be used as wiping products, such as industrial wipers, food service wipers, and the like. The web contains a mixture of cellulosic fibers and longer, strength building fibers. The web is foam formed and then subjected to one or more hydroentangling steps. After hydroentangling, the web is dried in a non-compressive manner.

COMPOSITE NONWOVEN AND PROCESS FOR PRODUCING A COMPOSITE NONWOVEN

A composite nonwoven fabric (1, 51, 61) and a process (100, 101, 102) for the production of the composite nonwoven fabric (1, 51, 61) are shown, wherein the composite nonwoven fabric (1, 51, 61) comprises at least one spunbonded nonwoven (8, 54, 64), which exhibits essentially continuous regenerated cellulosic filaments (4, 55, 65) deposited in a random orientation, and at least one layer (52, 62) of biobased biodegradable short fibers (14, 53, 63). So as to provide a fully biodegradable composite nonwoven fabric of the initially mentioned type, which exhibits a high stability and tensile strength as well as good absorption properties and haptic properties and, in addition, can be produced in a cost-efficient way, it is suggested that the composite nonwoven fabric (1, 51, 61) has at least one mixing area (56, 66) in which the filaments (4, 55, 65) of the spunbonded nonwoven (8, 54, 64) and the short fibers (14, 53, 63) are present in a state of physical interconnection.
