Multilayered nonwoven fabric containing submicron fibers, a method of manufacture, an apparatus, and articles made from multilayered nonwoven fabrics
20240125021 · 2024-04-18 ·

This document presents a novel method of manufacturing multilayered nonwoven fabrics consisting of submicron fibers, hydroentangled, meltfibrillated, and/or spunlaid web layers. The composite multilayered webs contain one or more submicron fiber webs placed between inner and outer layers of hydroentangled, meltfibrillated, and/or spunlaid web, forming a fabric that may be utilized in the manufacture of articles which serve as barriers, wipes or sorbent materials, or may have other potential applications. The created novel composite multilayered fabric may have increased loft, softness and bending length, may not be solely dependent upon an electrostatic charge to repel small particles and microbes, and may be formed from a broad selection of natural, synthetic, and recycled polymers, including petroleum- and plant-based, allowing polymer selection based on article lifecycle.
