Description

Technical Field

[0001] The utility model relates to a sofa fabric, in particular to an antistatic and breathable sofa fabric. Background Art

[0002] Sofa fabrics are significantly different from ordinary fabrics in many aspects, and these differences are mainly reflected in the following aspects: durability. Sofa fabrics usually pay more attention to durability because they need to withstand higher frequency of use and stronger friction. Polyester fabrics and leather fabrics are more durable and suitable for long-term use, while cotton and linen fabrics are more easily worn and need to be replaced regularly; comfort. Flannel fabrics and cotton fabrics are soft to the touch and more comfortable. They are suitable for use in resting places such as bedrooms. Although leather fabrics look high-end, they feel hard and may not be suitable for sitting or lying for a long time; breathability. Since sofas are usually used for rest and relaxation, the breathability of sofa fabrics is also required.

[0003] In summary, the fabrics used in common sofas are generally made of polyester fibers, which are weft-knitted. Weft-knitted fabrics have good elasticity and breathability, which can meet the requirements of comfort and breathability, while the wear resistance and high strength of polyester fibers themselves are sufficient to meet the requirements of durability. However, polyester is a chemical fiber, and due to the poor water absorption of chemical fibers, their antistatic properties are also poor.

[0004] If the sofa fabric is prone to static electricity, it will not only affect the user experience, but also easily absorb fine impurities such as dust, making it more difficult to clean. For this reason, the sofa fabric production industry urgently needs to develop an anti-static fabric that meets the characteristics required for sofa fabric applications. Summary of the invention

[0005] The utility model provides an antistatic breathable sofa fabric, which solves the problem in the prior art that chemical fiber sofa fabrics are prone to generate static electricity.

[0006] The above technical problems of the utility model are mainly solved by the following technical solutions: an antistatic breathable sofa fabric, comprising a knitted fabric layer, characterized in that it also includes an elastic wear-resistant layer compounded on the bottom of the knitted fabric layer, and a plurality of evenly dense air holes are opened on the elastic wear-resistant layer; the knitted fabric layer is weft-knitted by a first weft yarn, a second weft yarn, a first face yarn and a second face yarn, the first weft yarn is a wear-resistant yarn, the second weft yarn is a natural fiber yarn, the first weft yarn and the second weft yarn are evenly distributed and weft-knitted with each other in a ratio greater than 1, the first face yarn is a wear-resistant yarn, the second face yarn is a mixed conductive yarn, the knitted fabric layer is formed with a plurality of longitudinal grains L (L1, L2, L3, L4...) composed of curved weft yarns, the knitted fabric layer is formed with a plurality of longitudinal grains l (l1, l2...) composed of curved face yarns, and the spacing of the longitudinal grains l is 2 to 4 times (integer multiples) of the spacing of the longitudinal grains L.

[0007] The knitted fabric layer has good air permeability and anisotropic elasticity, but due to its knitting process, the distribution of the yarn is relatively loose, and it is more likely to have defects such as pilling, fuzzing, and broken threads caused by the yarn being hooked. The utility model compounds a layer of elastic wear-resistant layer at the bottom of the knitted fabric layer. The elastic wear-resistant layer can be used to reinforce the knitted fabric and strengthen the positioning of the yarn on the fabric. This can prevent the yarn from being severely deformed when being hooked. Even if the yarn is broken, it can prevent the broken yarn from being further derailed. At the same time, densely distributed air holes are arranged on the elastic wear-resistant layer to ensure that the air permeability of the knitted fabric layer is not greatly affected. The first weft yarn constituting the knitted fabric layer is a wear-resistant yarn, which is a chemical fiber yarn with the characteristics of high wear resistance and high strength. The second weft yarn is a natural fiber yarn with the characteristics of easy water absorption, breathability, and anti-static. By mixing natural fiber yarn and chemical fiber yarn, the fabric has the characteristics of both yarns. The first veil and the second veil mainly play a raising effect, making the fabric as a whole thicker and smoother. At the same time, since the second veil is a mixed conductive yarn, it further enhances the conductive properties of the fabric and reduces the accumulation of static electricity.

[0008] Furthermore, the hybrid conductive yarn is twisted from wear-resistant yarn and conductive yarn, and the strand ratio of the wear-resistant yarn to the conductive yarn is greater than 2.

[0009] Furthermore, the elastic wear-resistant layer is made of PU (polyurethane), and its thickness is between 0.5 and 1.2 mm; the diameter of the air holes on the elastic wear-resistant layer is between 1 and 2 mm, and the mesh number of the air holes is between 4 and 10. Polyurethane has excellent wear resistance and good elasticity, which just meets the performance requirements of the elastic wear-resistant layer.

[0010] Furthermore, the constituent fibers of the wear-resistant yarn are polyester or nylon, and the constituent fibers of the conductive yarn are metal wires.

[0011] Therefore, compared with the prior art, the utility model has the following characteristics: 1. An elastic wear-resistant layer is provided to reinforce the knitted fabric, which has the effect of strengthening the positioning of the yarn on the fabric, and densely distributed air holes are provided on the elastic wear-resistant layer to ensure that the air permeability of the knitted fabric layer is not greatly affected; 2. By mixing natural fiber yarns and chemical fiber yarns, the fabric has the characteristics of breathability, anti-static and high strength. BRIEF DESCRIPTION OF THE DRAWINGS
