Brassiere construction using multiple layers of fabric

Abstract

A body-shaping garment and fabric is provided. The garment includes an inner fabric layer and an outer fabric layer. The inner fabric layer is placed in an angular orientation relative to the outer fabric layer. Further, the inner fabric layer and the outer fabric layer have sufficiently isotropic hysteresis.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 248,787 filed on Oct. 11, 2005, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to fabrics and garments that provide support, shaping, and / or comfort to formable body areas, such as soft tissue areas. Body-shaping garments such as a brassiere or other body-shaping garment construction are fabricated with multiple layers of elastomeric fabric. [0004] 2. Summary of Related Art [0005] In the garment industry designers seek to develop women's body-shaping garments (e.g., brassieres, lingerie, girdles, stretch pants, and swimsuits) that are comfortable to wear, figure-enhancing, lightweight and aesthetically pleasing. In particular, brassiere constructions have two principal goals: (a) wearer comfort and (b) lift support for the breasts. The two principal...

Benefits of technology

[0014] Some embodiments utilize advances in the development of new fabrics in body-shaping garments including an engineered brassiere construction that contains multiple layers of fabric to provide for maximum comfort, shaping and control of the body of the wearer of a brassiere or other body shaping garment during movement and / or static conditions. It has been found advantageous to include multiple layers of particular materials in selected locations in a body-shaping garment such as a brassiere (e.g., bra cups or wings) in order to better provide the desirable features of comfort, body shaping and support. In the present invention, the layers of these fabrics may take on predetermined shapes and may be arranged in predetermined orientations relative to each other in the design of the cups of the brassiere construction. The layers of these fabrics may be used either alone or in combination with other materials that are sewn or otherwise applied to the fabrics. The layers of fabrics in the garment of the present invention may be molded.

[0017] Another embodiment includes a brassiere comprising a pair of cups, each of which further comprises an inner fabric layer and an outer fabric layer. In addition, the brassiere may include an angular orientation of the inner fabric layer relative to the outer fabric layer that can be determined by a value of a first angle, Θ1. Further, the inner fabric layer and the outer fabric layer have sufficiently isotropic hysteresis as defined further in the specification that allows the brassiere to conform to movements of the breasts with minimal slippage on the body.

[0020] Variation of the first angle Θ1, the second angle Θ2 and the isotropic hysteresis of each the inner fabric layer and outer fabric layer may determine the shaping, comfort and control of the brassiere. The first angle Θ1 and the second angle Θ2 may be predetermined in accordance with at least one of bust shape, bust density, and bust volume. By varying the angles Θ1 and Θ2, it can be possible to change the bust appearance, shape, and volume by changing the cup construction.

[0021] The shaping further comprises at least one of a minimizing effect, an up-lifting effect and a fuller bust effect. The shaping may be fully maintained during movement in multiple directions while at the same time the garment may stay in full contact with the wearer's body.

[0023] In a further embodiment is a garment including a body-shaping area including a multi-layer fabric having an inner layer and an outer layer; wherein the inner fabric layer defines a first X-X′ axis and first Y-Y′ axis and the outer fabric layer defines a second X-X′ axis and second Y-Y′ axis, and the inner fabric layer and outer fabric layer are oriented such that the first X-X′ axis of the inner fabric layer is at a first angle Θ1 to the second X-X′ axis of the outer fabric layer; and the inner fabric layer and the outer fabric layer each include an elastomeric fabric and each provide a multi-directional elasticity.

[0028] In a non-limiting example of some embodiments, the fabrics have elastomeric properties and isotropic hysteresis values. By using these types of fabrics, the some embodiments may provide softer and suppler body shaping garments with an even greater level of comfort and shaping ability than those produced by the known methods.

Problems solved by technology

For example, constrictive materials may press the breasts against the body with such pressure as to cause irritation and discomfort.

These changes may impact negatively the comfort of the wearer.

The separation of the garment from the formable body area during movement typically results in an undesirable loss of body shaping or support.

In other words, when the garment moves as a result of body movement, it may fail to return to its original position.

The lack of stretch in the cup after molding, limits wearer comfort and garment shaping ability.

Although the use of these stretchable woven fabrics was yet another step forward, the limitation of the stretchable direction to only one axis restricts the potential level of comfort and control provided by the brassiere formed with such fabrics.

It should be noted that three dimensional shaping ability with minimal garment slippage on the body and dynamic body shaping typically is not available in body-shaping garments such as brassiere cup designs (e.g., cups made from two-ply stretchable fabrics).

In fact in typical brassieres, wearer movement causes loss of shaping ability and garment slippage.
