Abstract
A process for producing a deformed nonwoven is described. The process includes the steps of: adjusting a water content of a nonwoven such that the nonwoven has at least one area having a water content of at least about 12% by weight of the nonwoven in the area, and subjecting the nonwoven to a mechanical deformation process. The deformation process is a mechanical deformation of the nonwoven and dewatering of the nonwoven to obtain a deformed nonwoven.
Claims21
A process for producing a deformed nonwoven comprising cellulose-based fibers, the process comprising;
- (a) adjusting a water content of a nonwoven such that the nonwoven comprises at least one area having a water content of at least about 12% by weight of the nonwoven in the area, and
- (b) subjecting the nonwoven to a mechanical deformation process, the deformation process comprising mechanical deformation of the nonwoven and dewatering of the nonwoven to obtain a deformed nonwoven.
A process for producing a deformed nonwoven comprising;
- (a) subjecting a fibrous web to an entanglement process to obtain a nonwoven,
- (b) adjusting a water content of the nonwoven such that the nonwoven comprises at least one area having a water content of at least about 12% by weight of the nonwoven, and
- (c) subjecting the nonwoven to a mechanical deformation process, the deformation process comprising mechanical deformation of the nonwoven, and dewatering of the nonwoven.
