FIELD OF THE INVENTION

The present utility model relates to the technical field of fabric straps. Particularly to a new fabric strap with a multi-layer structure.

BACKGROUND OF THE INVENTION

Presently, fabric straps are widely used in the textile industry and daily life, specifically in the garment industry. For example, fabric straps are essential accessories for underwear. In recent years, dramatic improvements have been made in the design and appearance of fabric straps. In order to make fabric straps more beautiful, patterns, decorations and color designs are changing with each passing day, yet less improvement has been made in the structure and function of fabric straps. Taking underwear straps as an example, one sees that most regular-sized underwear adopt narrow fabric straps as their shoulder straps to make the appearance look more exquisite. But for developed females, in order to keep the figure, the underwear straps need to bear large amounts of tension. Narrow straps will press hardly against the shoulders, thus causing discomfort for the wearer. In addition, it is easy for the narrow straps to generate impressions on the skin. Due to these problems, the present method is to connect a length of softer, thicker and wider fabric strap at the shoulder position of the shoulder strap through sewing, so as to satisfy the function required. However, it has complicated working procedures and leads to low work efficiency, which hinders automated production. Moreover, due to the present stitching position, the fabric strap affects the integral aesthetics and can cause skin allergies, red impressions or uncomfortable feelings, etc. due to friction. Another example is underwear wire casing. At present, two types of steel casing straps for underwear are available in the market: those that contain hot-melt yarn and those that do not contain any hot-melt yarn. The steel casing straps without the hot-melt element are structurally loose and prone to perforation. The steel casing straps with hot-melt yarn in the weft, which during the drying process are hot-melt and adhered to the cross-points of other yarn within the fabric, have an enhanced strength to effectively prevent the steel wire from perforating. For example, U.S. Pat. No. 6,071,578 discloses a tubular fabric with a hot-melt yarn, which is hot-melt to form a barrier on the inner wall of the tubular fabric to prevent perforation by steel wire, yet has complicated working procedures and high costs. In addition, the steel casing strap for underwear has a double-layer tubular structure with uniform thickness and would form a layer of hard film after the hot-melt yarn is heated. After the underwear wire is embedded, it will form a hard embossment, create uncomfortable stress and generate impressions when the embossment touches the wearer's skin, which provides a poor level of wearing comfort.

SUMMARY OF THE INVENTION

The utility model aims to provide a new fabric strap with a multi-layer structure, to improve upon the limitations of present technology. The multi-layer structure of the present utility model can form a cushion with erect fine hairs, which can relieve the pressure on the skin caused by the fabric strap and steel casing, making the underwear more comfortable. Meanwhile, proneness to penetration from steel wired casing can be reduced. The steel casing with the present structure, not only contains no hot-melt yarn, but also has incredible anti-bursting strength far more than the steel casing fabric containing hot-melt yarn, which can reduce the cost and simplify production process.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a new fabric strap with multi-layer structure contains fabric with at a least two-layer structure. Said fabric strap itself is the fabric with at least a two-layer structure interwoven and connected by a group or multiple groups of yarn according to a certain weave structure.

Said fabric strap is formed by integral weaving.

Said fabric strap is divided into several groups according to the yarn connected with every layer.

Said fabric strap contains at least two groups of the above connected at every layer of yarn.

Said yarn connecting fabric of every layer form the air cushion with a structure of erect fine hairs.

The upper-layer fabric of said fabric strap is interwoven by upper-layer wefts and upper-layer warps, the middle-layer fabric is interwoven by middle-layer wefts and middle-layer warps while the lower-layer fabric is interwoven by lower-layer wefts and lower-layer warps.

Said upper-layer fabric, middle-layer fabric and lower-layer fabric are woven integrally, forming the fabric strap itself with a tubular structure.

Said fabric strap body has a folding part in the middle position and the body of fabric strap folds and sews along the above folding part, forming a tubular structure. The middle of said tubular structure will form a wire channel used as the outer package of the wire.

Every layer of fabric of said fabric strap is a plain structure or patterned structure.

The peripheral surface of said fabric strap itself is a napped or unnapped surface.

Said fabric strap itself can be an elastic fabric or a non-elastic fabric strap.

Below are the advantages of the present utility model:

1. The new fabric strap with multi-layer structure of said utility model can be interwoven to the fabric strap with air cushion by velvet loom. Said air cushion (1) is the layer with erect fine hairs formed by one or more groups of nap warps (17) interwoven and connected with the upper- and lower-layers of fabric according to a certain weave structure. Since the air cushion composed of erect fine hairs are thicker and softer and also has the effect of relieving pressure, so when said fabric strap with air cushion of the present utility model is used as an underwear strap, the pressure on the skin caused by the fabric strap can be effectively relieved, thus increasing comfort of wear. In addition, since said fabric strap with air cushion for protection of the present utility model is integrally woven, having a smooth and even surface without connection points and comfortable hand feel, it can not only reduce processing operations, therefore improving production efficiency, but also ensure beautiful appearance of the clothing.

2. Said new fabric strap with a multi-layer structure of the present utility model woven by velvet loom, which can form a cushion (2) by interweaving by connecting two layers or more of fabric with a group or more of yarn (24) in the body of the fabric strap. A wire channel (20) will be interwoven above or below the cushion. If the wire casing fabric strap with said structure is adopted in the female underwear, no uncomfortable stress will be generated in the touching point of skin after wearing underwear. In addition, it can avoid leaving impressions on the skin, improve comfort of underwear wear and greatly increase the anti-bursting strength of wire casing.

3. Said new fabric strap with multi-layer structure of the present utility model can be woven into high-strength and anti-bursting fabric strap by loom. The body of fabric strap is connected by every layer of fabric with one or more groups of yarn (35) according to a certain weave structure. By folding and sewing said new fabric straps, a tubular structure will form. It will form a wire channel used as the outer package in the middle of the tubular structure, which greatly increases the anti-bursting strength and reduces the probability of suffering bodily harm due to wire. In addition, it can provide a better hand feel of the wire fabric strap and improve the comfort of underwear.
