Embodiment Construction

[0019] As used herein, the following terms shall have the meanings specified below:

[0020] "Absorbent article" means a wearable device that absorbs and / or contains fluids, and more specifically, a device that is placed next to or adjacent to the wearer's body to absorb and contain various exudates from the body. Absorbent articles may include diapers, training pants, adult incontinence underwear, feminine hygiene products.

[0021] A "longitudinal" direction is a direction extending parallel to the largest linear dimension of an article (typically the longitudinal axis), and includes directions within 45° of the longitudinal direction. As used herein, the "length" of an article or part thereof generally refers to the size / distance of the largest linear dimension, or generally refers to the size / distance of the longitudinal axis of the article or part thereof.

[0022] "Lateral" or "transverse" is orthogonal to the longitudinal direction, ie lies in the same principal plane ...

Abstract

The invention discloses a hydroentangled fiber structure. The hydroentangled fibrous structure can be incorporated into absorbent articles. The present invention also provides methods for forming hydroentangled fibrous structures.

Description

technical field [0001] The present disclosure generally relates to hydroentangled fibrous structures having improved performance characteristics, including flexural stiffness and fluid handling characteristics. Background technique [0002] Disposable absorbent articles such as feminine hygiene products are designed to absorb fluid from the wearer's body. Users of feminine hygiene products have several concerns. Leakage from products such as menstrual pads, and sanitary napkins in particular, is an important concern. How the product feels on the wearer's body is also an aspect of concern. To provide better comfort, current sanitary napkin products typically have a topsheet that is flexible, soft feeling, and non-irritating to the wearer's skin. The topsheet itself does not contain drained fluids. In contrast, the topsheet is fluid pervious to allow fluid to flow into the absorbent core. [0003] Over the years, topsheets have been improved to provide a cleaner, drier, a...
