Description

Technical Field

[0001] This application relates to the field of spandex textile technology, specifically to an antistatic spandex fabric. Background Technology

[0002] Spandex fabrics are widely used in clothing, sports equipment, and home furnishings due to their excellent elasticity and comfort. Currently, most spandex fabrics on the market are made of a blend of nylon / nylon and spandex. During wear, static electricity is easily generated due to friction and other physical processes. Especially in dry environments, the accumulation of static electricity can affect the wearer's comfort and, in some cases, even pose a safety hazard (static electricity can cause fires).

[0003] To address the static electricity problem in spandex fabrics, existing technologies primarily employ three methods. The first is to incorporate conductive fibers (such as metal wires or silver-plated polyester / nylon) into the fabric. However, metal wires result in a stiff fabric with low elasticity, while silver-plated fibers are prone to oxidation and blackening, and are costly. The second method involves adding antistatic particles, such as carbon black or carbon nanotubes, to polyester or nylon fibers. This method also has high production costs, and the addition of carbon black and carbon nanotubes gives the material a black color, significantly limiting color choices and failing to meet diverse color requirements. The third method involves adding antistatic auxiliaries during the fabric finishing process. However, fabrics produced using this method have poor wash resistance, and the auxiliaries are easily lost during washing.

[0004] Therefore, there is an urgent need for a fabric that can maintain good elasticity and comfort while also having good antistatic properties to meet the needs of the modern textile market. Utility Model Content

[0005] The purpose of this utility model is to provide an antistatic spandex fabric that can effectively prevent the accumulation and release of static electricity on the fabric surface, maintain good elasticity and comfort, and has wide applicability, suitable for various clothing categories such as ordinary work clothes, suits, sweaters, shirts, sports yoga pants, and medical surgical gowns.

The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1

[0029] In view of the problems existing in the background technology, Figure 1 A diagram illustrating the weave structure of a covered yarn according to an embodiment of this application is shown. For example... Figure 1 As shown, this application embodiment provides an antistatic spandex fabric, which is made by weaving covered yarn or antistatic spandex fiber. The covered yarn includes a covering layer 1 and a core yarn 2, and the core yarn 2 includes antistatic spandex fiber.

[0030] Specifically, the resistance of the antistatic spandex fiber does not exceed 10 ohms. 9 Ω.

[0031] In one implementation, the covered yarn is wound onto the core yarn 2 by the covering layer 1 in a spiral, air-twisted or other manner.

[0032] To verify the antistatic effect of the antistatic spandex fabric described in this embodiment, some specific tests have been conducted on this application in accordance with the implementation method provided in this application and with reference to the evaluation of the electrostatic properties of textiles in the national standard GB / T 12703.4-2010. Specifically, the resistivity of the antistatic spandex fabric described in this embodiment under no stretching, stretching by 2 times, and stretching by 3 times is measured. The specific evaluation results are shown in Table 1.

[0033] Table 1. Resistivity Measurement Results of Antistatic Spandex Fibers under Different Tension Degrees

[0034]

[0035] As can be seen from the measurement results in Table 1, the resistance of the antistatic spandex fiber prepared in this embodiment all meet the Class B standard specified in the current standard, and it has an antistatic effect.

[0036] Therefore, this embodiment effectively solves the problem of static electricity generation in existing spandex fabrics by setting a coating layer 1 on the antistatic spandex fiber to form a coated yarn, which is then woven into a fabric. It also maintains the good elasticity and comfort of spandex fabrics, avoiding the disadvantages of existing technologies such as conductive fiber blending and the addition of antistatic particles, which result in stiffer fabrics, reduced elasticity, increased costs, and limited color options, as well as the poor wash resistance of finishing agents. Therefore, this antistatic spandex fabric not only meets the modern textile market's demand for diverse colors but also achieves a good balance between functionality and comfort, showing broad application prospects.

[0037] Example 2

[0038] Figure 2 A structural diagram of an antistatic spandex fabric according to an embodiment of this application is shown, as follows: Figure 2 As shown, in one implementation, the antistatic spandex fabric is a plain weave fabric, the covering layer 1 includes polyester / nylon with a specification of 30D~100D, the antistatic spandex fiber has a specification of 20D~70D, and the draw ratio is 2.2~3.5.

[0039] Specifically, the plain weave fabric is constructed by parallel interlacing of warp and weft yarns. Both warp and weft yarns are made of 30D~100D polyester / nylon covering 20D~70D antistatic spandex, with a spandex draw ratio of 2.2-3.5. The fabric composition of the antistatic spandex fabric is 3%-10% antistatic spandex and 93%-97% polyester, with a weight of 100g / ㎡~200g / ㎡.

[0040] Using a fabric with a composition of 10% antistatic spandex and 90% polyester as a sample, half-life and surface charge density were tested. The test results are shown in Table 2 below:

[0041] Table 2. Results of half-life and surface charge density tests of antistatic spandex fabrics in Example 2.

[0042]

[0043] Based on the above test results, the antistatic spandex fabric of this embodiment 2, which is based on a plain weave structure of 10% antistatic spandex and 90% polyester, has good antistatic properties, can effectively prevent static electricity accumulation, and can also improve the softness and elasticity of the fabric, making it suitable for making work clothes.

[0044] Example 3

[0045] Continue reading Figure 2In one implementation, the antistatic spandex fabric is a plain weave fabric, the covering layer 1 includes wool with a specification of 60S~130S, and the antistatic spandex fiber has a specification of 20D~70D and a draw ratio of 2.2~3.5.

[0046] Specifically, this embodiment adopts a plain weave structure, with both warp and weft yarns made of 60S-130S wool covering 20D-70D antistatic spandex, and the spandex draw ratio is 2.2-3.5. The fabric composition of the antistatic spandex fabric is 2%-5% antistatic spandex and 95%-98% wool, with a weight of 200-300g / ㎡.

[0047] Using the antistatic spandex fabric, which comprises 2% antistatic spandex and 98% wool, as a sample in this embodiment, peak voltage, half-life, and surface charge density were measured. The results are shown in Table 3 below.

[0048] Table 3. Peak voltage, half-life, and surface charge density test results of the antistatic spandex fabric in Example 3.

[0049]

[0050] Based on the above test results, the antistatic spandex fabric of Example 3, woven with 2% antistatic spandex and 98% wool in a plain weave structure, exhibits excellent antistatic properties, effectively preventing static electricity accumulation and enhancing the fabric's softness and elasticity, making it suitable for suit production. Compared to existing technologies that achieve antistatic properties in suits by adding silver-plated fibers to the fabric, the antistatic spandex fabric of Example 3 has the advantage of lower production costs.

[0051] Example 4

[0052] In one implementation, the antistatic spandex fabric is a twill fabric, the covering layer 1 includes polyester or nylon with a specification of 30D~100D, and the antistatic spandex fiber has a specification of 20D~70D and a draw ratio of 2.2~3.5.

[0053] Specifically, this embodiment adopts a twill weave structure, using 30D~100D polyester or nylon to cover 20D~70D antistatic spandex, with a spandex draw ratio of 2.2-3.5. The fabric composition of the antistatic spandex fabric is 3%-6% antistatic spandex and 94%-97% polyester or nylon, with a fabric weight of 100-150g / ㎡.

[0054] Using the antistatic spandex fabric in this embodiment as a sample, peak voltage, half-life, and surface charge density were measured. The results are shown in Table 4 below.

[0055] Table 4. Peak voltage, half-life, and surface charge density test results of the antistatic spandex fabric in Example 4.

[0056]

[0057] Based on the above test results, the antistatic spandex fabric of Example 4 exhibits excellent antistatic properties, effectively preventing static electricity accumulation and making it suitable for shirt manufacturing. This example, by adding antistatic spandex to the polyester and nylon components of the shirt fabric, not only significantly improves the antistatic effect but also enhances the fabric's wearing comfort.

[0058] Example 5

[0059] Figure 3 A structural diagram of another antistatic spandex fabric in this embodiment is shown. Figure 3 As shown, in one implementation, the antistatic spandex fabric is a 1+1 pseudo-rib knit structure fabric, the covering layer 1 includes polyester, and the antistatic spandex fiber has any one of the specifications of 20D, 30D or 40D, with a draw ratio of 2.2~3.5.

[0060] Specifically, this embodiment employs a 1+1 faux rib structure, a structure typically used for the edge portions of fabrics. It achieves a unique effect by forming different loop structures on the front and back sides. In this structure, the loop on the front side is formed by a single yarn, while the loop on the back side is formed by two yarns. This creates a rib-like texture on the fabric surface, but it is not actually a true rib structure. Longer floats on the back of the faux rib can create a faux terry effect, as the longer floats form raised bumps on the back of the fabric, similar to terry loops. This effect increases the fabric's softness and warmth, while also adding a special texture. In this embodiment, the antistatic spandex fabric composition is 5%~15% antistatic spandex and 85%~95% polyester, with a fabric weight generally between 200~300 g / m².

[0061] Optionally, in this embodiment, the yarn used to weave the antistatic spandex fabric can be either covered yarn or bare spandex.

[0062] Using the antistatic spandex fabric in this embodiment as a sample, peak voltage and surface charge density were measured, and the results are shown in Table 5 below:

[0063] Table 5. Peak voltage and surface charge density test results of antistatic spandex fabric in Example 5

[0064]

[0065] Based on the above test results, it can be seen that the antistatic spandex fabric of Example 5 has good antistatic properties, can effectively prevent static electricity accumulation, and is suitable for making seamless underwear.

[0066] Example 6

[0067] In one implementation, the covering yarn is an empty-covered yarn, the specification of which is 30~100D polyester or nylon covered with 20D~70D antistatic spandex fiber, and the draw ratio of the antistatic spandex fiber is 2.2~3.5.

[0068] Figure 4 A schematic diagram of an empty-covered yarn structure in this embodiment is shown. Specifically, as shown... Figure 4 As shown, air-covered yarn is formed by simultaneously drawing an outer layer of polyester or nylon fiber (as the covering layer 1) and a core yarn (2) of antistatic spandex fiber through a nozzle and regularly spraying it with highly compressed air to create a yarn with a rhythmic air network of dots 3. In this embodiment 6, spandex fiber is combined with other fibers (polyester or nylon) to form a yarn with good elasticity and strength. The spandex content in the fabric composition is typically 5% to 20%.

[0069] Using the antistatic spandex fabric in this embodiment as a sample, peak voltage and half-life were detected, and the results are shown in Table 6 below:

[0070] Table 6. Peak voltage and half-life test results of antistatic spandex fabric in Example 6

[0071]

[0072] Based on the above test results, it can be seen that the antistatic spandex fabric of Example 6 has good antistatic properties, elasticity and breathability, and can effectively prevent static electricity accumulation, making it suitable for making socks and panties.

[0073] In summary, the antistatic spandex fabric provided in this application has excellent antistatic properties, effectively preventing the accumulation and release of static electricity on the fabric surface, maintaining good elasticity and comfort, and has wide applicability, suitable for various clothing categories such as general industrial clothing, suits, sweaters, shirts, socks, tights, and medical surgical gowns.
