Benefits of technology

[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

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 st

[0102] The last column of the table, coefficient of variation (S), provides a basis for comparison of the variation of the three results: L&L, W&W, and L&W for each fabric. The coefficient of variation (S) is the standard deviation of the 3 measurements divided by the mean and then multiplied by 100%.

[0103] Fabric 1A (commercially available from Penn Asia, Thailand) was made with Lycra® T902C spandex and the S value was within the limits for the invention. Fabric 1C (commercially available from H. Warshow and Sons, Inc., Milton, Pa.) was made with Lycra® T162B spandex and the S value is too high for the invention. Fabric 2C (commercially available from Ruey Tay, Taipei, Taiwan) was made with Lycra® T162C spandex and the S value is too high for the invention.

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...
