Low z high performance carbon composite materials
09546438 · 2017-01-17 · ·

A carbon/carbon part and processes for making carbon/carbon parts are provided. The process involves forming steps, carbonization steps and densification steps. The forming steps may include needling fibrous layers to form fibers that extend in three directions. Pressure may be applied to a fibrous preform at an elevated temperature to increase the fiber volume ratio of the fibrous preform. The densification steps may include filling the voids or pores of the fibrous preform with a carbon matrix.

ABSORBENT COMPOSITE COMPRISING A HYDROENTANGLED NONWOVEN

Absorbent composites suitable for a wide variety of uses (e.g., sorbent drapes, sorbent patches around a fenestration area, tray liners for surgical tools, incontinence pads and liners, other liners, etc.) are provided. The composite includes an absorbent nonwoven. The absorbent nonwoven may comprise a hydroentangled spunbond web. The composite also may comprise a liquid-impermeable film. One or more absorbent nonwovens of a composite may additionally comprise a three-dimensional pattern, for example, a three-dimensional pattern that has been imaged using hydroentanglement. Optionally, any one or more layers of the composites may comprise an antimicrobial additive.

Nonwoven fabric for increasing the availability of chlorine in solution

Wipes for preventing chlorine depletion suitable for commercial applications (e.g., industrial and consumer disinfectant wipes) are provided. The wipe includes at least one nonwoven layer, at least one pulp layer, and a nonionic modified siloxane additive. The at least one nonwoven layer and the at least one pulp layer may be hydroentangled to form a hydroentangled nonwoven fabric having a first surface and a second surface. Additionally, the nonionic modified siloxane additive may be disposed on at least one of the first surface or the second surface.

Nonwoven entanglement system and methods of manufacture
12325938 · 2025-06-10 · ·

Aspects herein are directed to a composite nonwoven textile that includes non-linear entangled seams and method and systems for producing the same. The composite nonwoven textile includes at least a first nonwoven layer, a second layer, and a fill material positioned between the first nonwoven layer and the second layer. When the composite nonwoven textile is formed into a garment, the regions between the non-linear entangled seams may help store and retain heat to provide insulation, and the non-linear entangled seams may help prevent shifting or drift of the fill material.
