A nonwoven web comprising a layer of polymeric fibers, wherein, based on the total number of polymeric fibers, at least 10% the polymeric fibers in said layer are coarse fibers having a fiber diameter of 4 μm or more, and at least 10% of the polymeric fibers in said layer are fine fibers having a fiber diameter of 2 μm or less. Also described herein is a method for making the nonwoven web, comprising melt-blowing a polymer mixture comprising two immiscible or partially miscible polymers.

A method for making a composite web comprises the steps of melt blowing a first flow of thermoplastic material including said first thermoplastic material towards at least one collecting suction surface moving in a feed direction; dispensing a flow of particulate material including a particulate material towards the collecting suction surface in such a way as to intercept the first flow of thermoplastic material in an intercept zone; the first flow of thermoplastic material and the flow of particulate material intercept each other in the intercept zone at an intercept angle of between 1 and 90 sexagesimal degrees, preferably between 15 and 40 sexagesimal degrees.

The present disclosure relates to a polyethylene fiber and a method for preparing thereof, and more particularly to a polyethylene fiber, a method for preparing thereof, and an apparatus for preparing thereof, which has excellent wearing and touch sensation with processing convenience into woven fabrics and knitted fabrics in use in applied products by reducing the stiffness of fiber having the same physical properties using an enforced necking method in a spinning process.

Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

A fiber-wrapped smokeless tobacco product includes smokeless tobacco and a plurality of polymeric fibers surrounding the smokeless tobacco. The polymeric fibers can have a basis weight of 5 gsm or less and a diameter of less than 100 microns. In some cases, the polymeric fibers are melt-blown polymeric fibers. In some cases, the polymeric fibers are centrifugal force spun polymeric fibers. A method of preparing a fiber-wrapped smokeless tobacco product includes melt-blowing or centrifugal force spinning a plurality of polymeric fibers to create an polymer deposition zone and passing a body comprising smokeless tobacco through the polymer deposition zone. In some cases, an electrostatic charge can be applied to the plurality of polymeric fibers, the body, or a combination thereof. In some cases, a spin is applied to the body when passing through the polymer deposition zone.

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.

Structures, for example fibrous structures, such as absorbent material, for example absorbent core material including particles, for example super absorbent polymer particles (SAP particles), and processes for making same are provided.

A method of making a nonwoven from continuous filaments is provided. The method comprises the steps of spinning continuous filaments from a spinneret to move along a vertical travel path in a vertical travel direction, cooling and stretching the filaments downstream of the spinneret in a cooler and a stretcher, and depositing the cooled and stretched filaments at a deposition location on a foraminous belt moving horizontally underneath the cooler and stretcher and having an array of openings of which a portion are plugged with a sealing compound to create a partially plugged foraminous belt. The method comprises drawing air downward through unplugged openings in the foraminous belt to stabilize the continuous filaments deposited on the foraminous belt, and pre-consolidating the deposited nonwoven into final form.

A nonwoven fabric including continuous filaments forms the nonwoven fabric. The nonwoven fabric having a first surface, a second surface, and a visually discernible zone on the second surface and extending from the first surface. The visually discernible zone has a pattern of three-dimensional features. The first surface is relatively flat. A first plurality of the three-dimensional features have different Z-direction maximum dimensions relative to the first surface. A second plurality of the three-dimensional features have substantially the same Z-direction maximum dimensions relative to the first surface. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property.
