Description

Tubular fabric with reinforced fabric structure

technical field

The utility model relates to textiles, in particular to tubular fabrics in narrow-width woven fabrics.

Background technique

Certain undergarments, such as brassiere, typically have a textile casing, typically a woven tubular fabric, that accommodates a shaped underwire. At present, the underwire fabric covers for underwear on the market can be mainly divided into two categories: one is that the fabric components of the fabric covers contain thermal fuses; the other is that the fabric components do not contain thermal fuses. The structure of the steel ring fabric sleeve without thermal fuse is relatively loose, which makes the steel ring penetration phenomenon prone to occur at both ends of the fabric sleeve. The fabric cover with thermal fuse steel ring is added to the weft yarn, and the thermal fuse is melted by heat during the post-dyeing process of the fabric, which can stick the interweaving points in the fabric together, so as to improve the strength of the fabric and effectively prevent Steel ring penetration phenomenon, for example, US Patent No. 6,071,578 of Roy Richardson et al. discloses a tubular fabric containing thermal fuses, which form a barrier on the inner wall of the tubular fabric by thermal fuses to prevent steel rings from penetrating .

Utility model content

The utility model aims at the problem that the rim fabric cover without thermal fuse is easy to penetrate, and provides a tubular fabric (hereinafter also referred to as rim cover) containing spandex raw material yarn. The raw material composition of the tubular fabric does not contain any thermal Fuses or materials similar to thermal fuses can reach or even exceed the strength of steel ferrules containing thermal fuses after improved processing, effectively preventing penetration problems.

The utility model is achieved in that:

The utility model provides a tubular fabric, which is formed by interlacing weaving of several warp yarns and weft yarns, at least one of the raw warp yarns is spandex yarn, and the floating length of the spandex yarn on the inner tube wall surface of the tubular fabric is not less than 3 weft yarns.

The structure of the spandex yarn in the tubular fabric is preferably three-in-one-down, three-in-one-up. Of course, those skilled in the art can also choose other structures, as long as the selected structure can make the spandex yarn cover the inner wall surface of the tubular fabric in a large range.

Preferably, the spandex yarn accounts for not less than 6% of the total fabric weight, and the weft density is not less than 14 picks/cm.

The preferred range of the spandex yarn to the total weight of the fabric is 6%-12%, and the preferred range of the weft density is 14 weft/cm-30 weft/cm.

The spandex yarn accounts for more preferably 8% of the total weight of the fabric, and the weft yarn density is more preferably 15.7 picks/cm.

There are at least two kinds of warp yarns, one of which is spandex yarn, and the other or more can be nylon yarn, or other suitable raw material yarns.

The raw material yarn of the tubular fabric may not contain any thermal fuse, or other raw material yarns with properties similar to the thermal fuse.

The tubular fabric of the utility model uses a special structure different from the past, and the floating point of the spandex is longer, so that the inner wall of the tubular fabric is covered with a large amount of spandex yarn, thereby enhancing the strength of the fabric. When the steel ring penetrates the steel ring sleeve, it must first penetrate the inner wall, so appropriately increasing the spandex yarn on the inner wall can increase the strength of the steel ring sleeve and effectively prevent penetration. The utility model can be applied to clothing, especially tubular fabrics in the field of underwear, such as brassieres, women's jackets, swimsuits, and the like.

Detailed ways

Due to its excellent elasticity and good recovery performance, spandex can play a good shrinkage effect in the fabric, thereby achieving the effect of strengthening the penetration resistance of the fabric. Fig. 1 to Fig. 3 are the schematic structural diagrams of ordinary rim sleeve 1' class fabrics, as can be seen from the figure, the spandex yarn 2' is in the middle layer of the fabric, and the spandex warp floating point 3' is short.

Fig. 4 to Fig. 6 show the structure diagram of an embodiment of the tubular fabric of the present invention. The fabric cover (or steel ring cover) 1 is composed of sheet structures 11, 12, and the two sheets 11, 12 are sewn together by seaming threads to form a hollow tubular cover body. Each ply is woven from one weft yarn and several warp yarns. After testing, we found that a large amount of spandex yarn is covered on the inner wall of the inner layer of the steel ring, which can effectively strengthen the strength of the fabric. The warp raw material of the fabric cover of the present utility model contains at least spandex yarn, and the surface of the inner wall of the fabric cover after weaving is covered with spandex yarn 2, and the floating thread 3 of the spandex warp yarn on the fabric surface is longer, at least more than three weft yarns, the fabric structure It can be achieved by the warp arrangement shown in FIG. 7 and the warp weave shown in FIG. 8 .

Please refer to Fig. 9, the curves in the figure represent the spandex warp yarns, the circles represent the weft yarns, and the figure only shows the direction of the spandex warp yarns and weft yarns of the upper and lower layers. In this embodiment, the floating threads of spandex warp yarns on the surface of the inner wall of the fabric sleeve span three weft yarns at intervals of one weft yarn, that is, the structure is three-in-one-down, three-in-one-up. Of course, other fabric structures similar to this structure to make the floating lines on the surface of the spandex warp yarns longer can also be used.

The following are the comparison results of the spandex yarn percentage content and the puncture strength test of the steel ring between the prior art and the utility model.

samples thermal fuse   Spandex yarn content Weft density (weft/cm) Average strength (Kg) Martha requirements (25.0Kg) A have 3.6% 11.7 20.0 no B none 8.0% 15.7 29.0 Yes

Note: Sample A is the steel ring cover fabric containing thermal fuse, and sample B is the steel ring cover fabric without thermal fuse of the utility model.

In this embodiment, the spandex yarn accounts for 8% of the total fabric weight, and the weft density is 15.7 weft/cm, which is the test data for better results. According to the test results, the purpose of the utility model can be achieved, and the parameters of the spandex content and weft density of the fabric to effectively prevent the steel ring from being pierced are as follows: the spandex yarn accounts for not less than 6% of the total weight of the fabric; the weft density is not less than 14 weft/cm～30 Weft/cm. Preferably, the spandex yarn accounts for 6% to 12% of the total weight of the fabric, and the weft density ranges from 14 weft/cm to 30 weft/cm.

It can be seen from the above table that the spandex yarn of sample A is in the middle of the fabric and the spandex content is only 3.6%, the weft density is 11.7 weft/cm, and its average strength does not reach the 25.0Kg required by Martha.

The spandex yarn of sample B is covered on the inner wall of the fabric sleeve, and when the spandex content increases to 8.0%, the strength is obviously improved. The fabric cover of the utility model is suitable for weaving, and the greater the weft density is when the woven fabric is weaved, the harder the handle is, and the better the strength is, the less likely it is to burst the fabric. It can be seen from the above table that when the weft yarn density is increased from 11.7 weft/cm to 15.7 weft/cm, the strength is enhanced, exceeding the 25Kg required by Martha.

At present, all tubular fabrics on the market are of double-layer structure, and the structure of the spandex yarn in the fabric is one middle, one upper, and one middle lower. This structure is very common, only spandex yarn is interwoven in the middle of the tubular fabric. However, the spandex yarn weave structure of the tubular fabric of the present invention is three middles and one upper, and three middles and lower, which breaks the thinking forbidden zone of the tubular fabric structure. The spandex yarn has a structure of three middles, one upper and three middles, which can cover the inner wall of the tubular fabric with spandex to the greatest extent, effectively improving the strength of the tubular fabric, and the tubular fabric has been tested by relevant testing institutions in line with Martha's test standards.

The used machine of the fabric of the present utility model is preferably made by Muller of Switzerland, and the machine model is a narrow loom of NF 6/27. The spandex yarn product is preferably 420D, 40 spandex yarns produced by Japan Asahi Kasei. Of course, the fabric cover of the present utility model can also be implemented by selecting other suitable machines or spandex raw material yarns of other models by those skilled in the art.

The above-mentioned embodiments are only for explaining and describing the fabric cover of the present utility model, and the implementation includes but not limited to the above-mentioned examples. It should be understood that various other variations or modifications can be made without departing from the scope of the present invention.
