Problems solved by technology

It is not practical for bras, and bra straps, to be specially designed for each wearer.
Because straps cannot be made shorter, certain wearers obtain no or little support.
Thus, as the elastic is stretched, the force applied by the strap rapidly increases and the bra becomes uncomfortable to the wearer.
First, the ring and slide system creates a thick bulky area near the slider which is uncomfortable to the wearer and visible through outer garments.
Second, the slider may move during use so as to loosen the strap, causing discomfort, a lack of support, and a loose fit.
Third, the ring and slide system adds to the cost of the bra.
The straps on this bra provide very little support.
However, such a bra fails to provide adequate support during normal use.
Additionally, the straps of this bra are prone to slide off the shoulder of the wearer.

example 1

[0061]According to a first exemplary embodiment of the present invention, a strap is formed by weaving a covered elastomeric yarn, a face yarn, a back yarn, a binding yarn, two weft yarns, and a catch thread. The details for these yarns are provided below.

[0062]The details of the covered elastomeric yarn are as follows. A core elastomeric yarn of 400 decitex is provided. The core yarn is stretched to a draft of 4.9 and is covered by a bottom cover yarn and a top cover yarn while the core yarn is stretched. Draft is a unitless measure of how much a single unit of elastomeric yarn will be stretched to at the point at which the elastomeric yarn is covered. For example, a draft of 4.9 indicates that 1 unit of an elastomeric yarn will be stretched to 4.9 units. The bottom cover yarn is 1 / 20 / 20 Polyamide 6.6 Z textured. The top cover yarn is 1 / 20 / 20 Polyamide 6.6 Z textured. The core yarn is covered by the bottom cover yarn at a rate of 800 Turns Per Meter (“TPM”). TPM refers to number of...

[0068]According to a second exemplary embodiment of the present invention, a strap is formed by weaving a covered elastomeric yarn, a face yarn, a back yarn, a binding yarn, two weft yarns, and a catch thread. The details for these yarns are provided below.

[0069]The details of the covered elastomeric yarn are as follows. A core spandex yarn of 400 decitex, is provided. The core yarn is stretched to a draft of 3.4 and is covered by a cover yarn while it is stretched. The cover yarn is 1 / 20 / 20 Polyamide 6.6 Z textured. The core yarn is covered by the cover yarn at a rate of 900 TPM.

[0070]The details of the remaining yarns are as follows. The face yarn is 1 / 44 / 12 / 150 Polyamide 6 BT flat. The back yarn is 2 / 44 / 12 / 100 Polyamide 6 SD textured yarn. The binding yarn is 1 / 44 / 12 / 150 Polyamide 6 BT flat. The first weft yarn is 1 / 44 / 12 Polyamide 6 BT flat. The second weft yarn is 1 / 44 / 12 Polyamide 6 BT flat. The catch thread is 1 / 44 / 12 Polyamide 6 SD textured.

example 3

[0088]According to a third exemplary embodiment of the present invention, a strap has two sections: a body part and a Jacquard area. The Jacquard area comprises a split-strap part and a binding area as shown in FIGS. 9 and 10. The details of these yarns are provided below. The strap is formed by weaving a covered elastomeric yarn, two weft yarns and a binder yarn. A gut yarn is provided inside the tubular strap to fill the tubular strap and thereby provide improved comfort for the wearer.

[0089]The details of the covered elastomeric yarn are as follows. A 78 decitex spandex yarn is provided as the core elastomeric yarn. The core yarn is stretched to a draft of 2.9 and is covered by a cover yarn while the core yarn is stretched. The cover yarn is 1 / 78 / 24 Polyamide 6 SD Textured z twist. The core yarn is covered by the cover yarn at a rate of 804 TPM.

[0090]The details of the remaining yarns are as follows. The gut yarn is 2 / 78 / 24 Polyamide SD textured N6. The first weft yarn is 1 / 44 / 12...

Abstract

A bra strap has stretch properties such that the strap exerts a force that is sufficient to provide adequate support but does not exceed that which is comfortable to the wearer over a wide range of elongation. Thus, the bra strap may be worn by women of varying heights without the need to change the length of the strap prior to use.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 369,539 filed Jul. 30, 2010, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to straps, and more particularly, to straps for use in brassieres, sports bras, swimwear, and the like.[0004]2. Discussion of the Related Art[0005]It is not practical for bras, and bra straps, to be specially designed for each wearer. Instead, a given bra style may be intended to be worn by women of varying heights. For example, the distance from the top of a bra cup to the top of the shoulder of a wearer may vary substantially requiring bra straps to be shorter or longer for different wearers. Because straps cannot be made shorter, certain wearers obtain no or little support. In other cases, the straps must be stretched to fit a wearer; however, conventional bra straps are made of an elastic having a high modulus. Thus, as the elastic is st...
