Abstract
Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.
Claims23
A process for making a fibrous structure, the process comprising the steps of:
- a. providing a die comprising one or more filament-forming holes, wherein one or more fluid-releasing holes are associated with one filament-forming hole such that a fluid exiting the fluid-releasing hole is parallel or substantially parallel to an exterior surface of a filament exiting the filament-forming hole;
- b. supplying at least a first polymer to the die;
- c. producing a plurality of filaments comprising the first polymer from the die;
- d. combining the filaments with solid additives to form a mixture;
- and
- e. collecting the mixture on a collection device to produce a fibrous structure.
