Coforming processes for commingling two or more separate materials, for example solid additives, for example fibers and/or particulates, and filaments, and equipment; namely, forming boxes, useful in such coforming processes and more particularly to coforming processes for commingling filaments with one or more fibers, such as pulp fibers, and forming boxes useful therein are provided.

Coforming processes and forming boxes used therein

A spatially controllable, for example CD controllable, eductor, and more particularly an eductor that is capable of providing a variable motive fluid and processes using such an eductor are provided.

Spatially controllable eductor for managing solid additives and processes using same

A method for modeling a manufacturing process for an absorbent article. The method may be used in the creation of absorbent articles.

Method for modeling a manufacturing process for a product

An apparatus suitable for separating particles and methods for using such apparatus are provided.

Apparatus for separating particles and methods for using same

The present disclosure is directed to a fibrous core comprising a fluted layer; and a liner disposed on the fluted layer. The fluted layer and the liner are helically wound defining a longitudinal core axis.

Fibrous cores

A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct, the NACA duct having an intake opening and walls that diverge in increasing cross-sectional area to an exhaust opening having greater cross sectional area than the intake opening; and submerging the intake opening into the boundary layer to scavenge dust-carrying air from the boundary layer.

Method and apparatus for particulate removal from moving paper webs

The present invention relates to a method for airborne particle contamination control, comprising: creating a simulation by modeling a turbulent airflow in an environment that includes an equipment of interest; plotting a flow parameter on the simulation to visualize a flow field of air according to a current design; creating an injection point on the simulation for particles in the environment; determining a particle concentration of the particles; determining, by a computing device and from the particle concentration, whether the current design provides contamination control; in response to determining that the current design does not provide contamination control, creating a modified design; and providing the modified design for implementation. The present invention further relates to a computing device for airborne particle contamination control. The present invention still further relates to a non-transitory computer-readable medium for airborne particle contamination control.

Systems and methods for airborne particle contamination control

An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer.

Absorbent articles which provide superior protection against wet through under impact or sustained pressure, and high convective air flow therethrough for skin health and comfort benefits. An absorbent article comprising an absorbent core and an absorbent barrier structure, wherein the absorbent barrier structure has a hydrohead value of at least about 10 mBars; a convective air permeability of at least about 10 Darcy/mm; and a liquid impact transmission value of less than about 20 g/m.

Absorbent barrier structures having a high convective air flow rate and articles made therefrom

Absorbent articles which provide superior protection against wet through under impact or sustained pressure, and high convective air flow therethrough for skin health and comfort benefits. In particular, an absorbent article comprising an absorbent core and an absorbent barrier structure, wherein the absorbent barrier structure has a hydrohead value of at least about 10 mBars; a convective air permeability of at least about 10 Darcy/mm; and a liquid impact transmission value of less than about 20 g/m.
