Description

{HOSIERY WITH GRADUATED COMPRESSION PANTY}

The present invention relates to hosiery apparel having pants specifically designed for comfortable wear without a conventional waistband.

The main function of the waistband is to hold clothes. For this purpose in hosiery, a narrow band is knitted with a strong elastic yarn on top of the panty part. This conventional waistband may include an elastic band or welt knitted as described in U.S. Patent No. 6,276,176. All these structures generally form a narrow, high compression band at the waist. Due to the high compression, localized to a small area, hosiery with this type of conventional waistband are sometimes uncomfortable to wear. Another drawback of this type of structure is the curvature of the waistband.

What is needed is a garment structure for a comfortable hosiery without a conventional waistband. Despite the absence of a conventional waistband, the garment must not slip down and the upper portion of the panty portion should not curl.

In one aspect, the hosiery having legs and panties excludes conventional waistbands that are replaced by a specially designed, incremental compression panty. The pressure from the bottom of the panty to which the leg is attached corresponds roughly to the waist of the wearer but increases progressively from the bottom of the waist to the top of the panties that can rest on the waist or waist. This incremental compression panty is selected from a single layer structure, a double layer structure, and a partial double layer structure. The panties include a single layer, a double layer, or a partial double layer that includes incremental compression in such a way as to provide sufficient compression to hold the garment while preventing curling.

As used herein, the term "spandex" means a manufacturing filament in which the filament forming material is a long chain synthetic polymer comprising at least 85% by weight of segmented polyurethane. A variety of different spandex compositions are useful among others, in some embodiments, such as pantyhoses of polyether and co-polyether-based spandex. Specific examples of commercially available spandex yarns include the trade names LYCRA® 162B, Lycra® 163C, and Lycra® 163C available from INVISTA S.Ar.l. of Wichita, KS, Include those available under LYCRA® 163A, LYCRA® 178C, LYCRA® 902C, and LYCRA® 777C (especially useful for anti-laddering hosiery).

The terms "panty hose" and "hosiery" are used interchangeably herein and include a panty that has at least a circular knit structure and typically extends from around the wearer's waist to the crotch, It is interpreted to include apparel that includes.

The panty hose includes any suitable combination of elastic yarns or elastomer yarns with hard yarns. Elastic yarns or elastomer yarns may be included in every course or every once-through course (other structures may be useful if patterned hosiery is required). A suitable elastomer yarn is a spandex that can be used bare or covered by itself. The coating may be single or double coating, air coating, air jet textured, entangled, core-spun, and the like.

Examples of hard yarns include polyamide yarns such as nylon 6, nylon 6/6 (PA 66), nylon 10, nylon 12, nylon 6/10, nylon 6/12, and combinations thereof. The hard yarn can be flat or textured. The panty hose may include yarns selected from polyamide-coated spandex yarns and blends of polyamide-coated spandex yarns and polyamide yarns.

Increasing compression of the panties can be achieved by changing and / or increasing the tensile strength of the yarn at the time of knitting as well as by use of yarns that change and increase linear density (decitex). One device for measuring and controlling the tensile strength of a yarn is BTSR International SpA, a constant tension available from Italy, Constant tension feeder (KTF).

The amount of suitable spandex fibers may be from about 10% to about 30%, including from about 12% to about 26%, and from about 15% to about 22% of the total yarn weight.

The incremental compression panties can be selected from a single layer structure, a full double layer structure, and a partial double layer structure. Each of these structures excludes waist bands that are no longer needed due to the incremental structure. Increasing compression is provided by a series of areas with different compression levels increasing from the area near the bottom (leg attachment) to the top (waist). In the final structure of the garment, the top of the panties has the highest level of compression. Suitable area The number may include from about 2 to about 10 regions, such as from about 3 to about 5 regions, with different levels of compression. This includes about 3 regions of different pressures.

The different pressing areas may differ depending on any suitable amount to provide the required comfort while maintaining the ability to keep the panties in place on the wearer. The increased pressure may be from about 2 times to about 20 times as high as from the bottom to the top. Which includes about 3 to about 10 times, and about 4 to about 9 times as high, depending on the overall level of compression of the panties.

The percentage of the number of courses in each area depends on the incremental pressure required and the total number of areas required . 3 region, the lower region can comprise from about 10% to about 50% of the total number of courses of panties, which can range from about 15% to about 40% and from about 20% to about 30%, and from about 15% About 25%.

The three different structures are described in more detail below:

Fully double layer panty:

In this structure, the double layer is knitted in the panty portion over the entire length of the panty. This double layer can be provided by knitting in an individual layer. The double layer panty can also be produced by knitting a single layer and then folding and sewing the layers together. This is accomplished by knitting a single layer that increases the compression from the leg attachment point to the center point of the highest compression and then reduces the compression to the top. This upper portion is folded in a folded manner to touch the leg attachment portion, and wrinkles are formed at the highest pressing point which can roughly correspond to the waist of the wearer. As completed, there is sufficient pressure on the upper portion of the pant (roughly corresponding to the wearer's waist) to hold the garment and also to prevent curling of the garment; The compression of the panty portion is increased as it goes from the lower portion (leg attachment portion) to the upper portion (waist) of the panty. The increase in compression is achieved by a combination of yarn selection and knitting machine settings, such as elastic tension and sealing length.

Partial double layer:

Alternatively, similar to that described above for the fully double layer, the double layer is knitted only at the top of the panty portion. However, this double layer portion is significantly larger than the standard (double layer) waistband, which is a conventional waistband. The partial bilayer may be from about 10% to about 50% of the total number of courses of the panties, which comprises from about 15% to about 40% and from about 20% to about 30%. Also in this structure, the compression of the panties portion is increased as it goes from the lower portion to the upper portion of the panty in order to hold the garment and also to provide the upper portion of the panty with sufficient pressure to prevent curling of the garment. The increase in compression is achieved by a combination of yarn selection and knitting machine settings, such as elastic tension and sealing length.

Single layer:

Another alternative is single-layer incremental compression panties. This includes an incremental compression panty with a lower compression at the lower portion of the pant (leg attachment portion) and a higher compression at the upper (waist portion). This structure includes multiple regions similar to fully doubled and partial double layer panty structures while also avoiding the need for a conventional waistband (i.e., a narrow band with higher compression at the top of the panties). The increase in compression is achieved by a combination of yarn selection and knitting machine settings, such as elastic tension and sealing length.

The legs may include yarns having the same denier (linear density), lighter denier or heavier denier as yarns of the panties. The legs (left and right) may have a structure selected from the group including sheer, translucent, and opaque. To further reduce pain and enhance comfort when worn, the legs may each include an upper thigh portion, the upper thigh portion including a stiffening sheath.

The structure of the legs can be any of a variety of well known in the art. This includes the entire range from panty to toe, toe exposure, ankle length, knee length or any other length required for legs.

The features and advantages of the present invention will be more fully described by the following examples presented for purposes of illustration and should not be construed as limiting the invention in any way.
