Description

Technical Field

[0001] This utility model relates to the technical field of automotive sunshade fabrics, specifically to high-strength, wear-resistant warp-knitted automotive sunshade fabrics. Background Technology

[0002] With the increasing popularity of automobiles, to prevent excessively high interior temperatures caused by prolonged exposure to the summer sun, which can damage interior leather and dashboard materials and lead to premature aging, sunshade fabrics will inevitably be widely used in automotive sunshade systems. Currently, commonly used fabrics for automotive sunshades on the market include coated polyester fabric, single-layer polyester fabric, and mesh polyester fabric.

[0003] For example, the existing publication number CN221740584U specifically discloses an M26 fleece-lined, light-blocking, environmentally friendly car sunshade fabric. This fabric body comprises a fabric body woven from recycled composite yarns of the first guide bar and high-elasticity shrinkage yarns of the second guide bar. The first guide bar is a 10 / 45 five-needle plain weave, and the second guide bar is a 12 / 10 two-needle plain weave. The recycled composite yarns include high-shrinkage yarns and high-elastic polyester yarns, which are spirally twisted together. The high-shrinkage yarns shrink when heated, thereby reducing the gap between the first and second guide bars, resulting in a higher overall fabric density. Simultaneously, the high-shrinkage yarns have poor overall elongation properties, making the entire fabric less prone to stretching under stress after weaving, thus preventing light from easily passing through the gaps in the fabric and enhancing the sun-shading effect.

[0004] However, the following problems were found in the implementation of the relevant technology: When the above-mentioned car sunshade fabric is used, due to its weaving structure, the fabric has low structural strength and poor wear resistance, which leads to the existing car sunshade fabric being easily damaged and having a short service life. Therefore, we propose a high-strength wear-resistant warp-knitted car sunshade fabric. Utility Model Content

[0005] To address the shortcomings of existing automotive sunshade fabrics, such as low structural strength, poor abrasion resistance, and frequent damage, this invention provides a high-strength, abrasion-resistant warp-knitted automotive sunshade fabric.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model relates to a high-strength, wear-resistant sunshade curtain warp-knitted automotive fabric, comprising a fabric body, a composite warp-knitted layer on the lower surface of the fabric body, a reinforcing layer on the lower surface of the composite warp-knitted layer, a wear-resistant inner layer on the lower surface of the reinforcing layer, and a wear-resistant outer layer on the upper surface of the fabric body.

[0008] As a preferred embodiment of the present invention, the composite warp-knitted layer includes a knitted outer fabric layer and a woven base fabric layer. The knitted outer fabric layer is connected to the lower surface of the fabric body, and the woven base fabric layer is connected to the upper surface of the reinforcing layer. An adhesive layer is provided between the knitted outer fabric layer and the woven base fabric layer.

[0009] As a preferred technical solution of this utility model, the pattern of the outer layer of the knitted fabric is the following structure: GB1 comb: 1-0 / 1-2 / 1-0 / 1-2 / 4-5 / 4-3 / 4-5 / 4-3 / / , GB2 comb: 4-5 / 4-3 / 4-5 / 4-3 / 1-0 / 1-2 / 1-0 / 1-2 / / , GB3 comb: 1-0 / 4-5 / / .

[0010] As a preferred embodiment of the present invention, the reinforcing layer includes a glass fiber cloth layer, which is disposed on the lower surface of the woven base fabric layer. A high-temperature ceramic fiber woven layer is disposed on the lower surface of the glass fiber cloth layer, and the high-temperature ceramic fiber woven layer is connected to the upper surface of the wear-resistant inner layer.

[0011] As a preferred embodiment of the present invention, the wear-resistant inner layer includes an aramid fabric, which is disposed on the lower surface of the high-temperature ceramic fiber woven layer, and a polyester fiber cloth layer is disposed on the lower surface of the aramid fabric.

[0012] As a preferred embodiment of this utility model, the wear-resistant outer layer includes a nylon fabric layer, which is disposed on the upper surface of the fabric body. An Oxford fabric layer is disposed on the upper surface of the nylon fabric layer, and an ultra-high molecular weight polyethylene fiber fabric layer is disposed on the upper surface of the Oxford fabric layer.

[0013] The beneficial effects of this utility model are:

[0014] This high-strength, wear-resistant warp-knitted automotive sunshade fabric, through the addition of reinforcing layers—combining glass fiber cloth layers and high-temperature ceramic fiber woven layers—enhances the structural strength of the warp-knitted automotive fabric. The wear-resistant inner layer, combining aramid and polyester fiber cloth layers, improves the wear resistance of the inner surface. Furthermore, the wear-resistant outer layer, combining nylon, Oxford cloth, and ultra-high molecular weight polyethylene fiber cloth layers, enhances the wear resistance of the outer surface. This improves the overall structural strength and wear resistance of the warp-knitted automotive fabric, effectively extending its service life. It overcomes the shortcomings of existing automotive sunshade fabrics, such as low structural strength, poor wear resistance, and frequent damage. Attached Figure Description

The reinforcing layer 3 enhances the structural strength of the warp-knitted automotive fabric, the wear-resistant inner layer 4 improves the wear resistance of the inner surface of the warp-knitted automotive fabric, and the wear-resistant outer layer 5 improves the wear resistance of the outer surface of the warp-knitted automotive fabric. This improves the overall structural strength and wear resistance of the warp-knitted automotive fabric, solving the defects of existing automotive sunshade fabrics, such as low structural strength, poor wear resistance, and frequent damage.

[0024] The composite warp-knitted layer 2 includes a knitted outer fabric layer 21 and a woven base fabric layer 22. The knitted outer fabric layer 21 is connected to the lower surface of the fabric body 1, and the woven base fabric layer 22 is connected to the upper surface of the reinforcing layer 3. An adhesive layer 23 is provided between the knitted outer fabric layer 21 and the woven base fabric layer 22. The pattern of the knitted outer fabric layer 21 is the GB1 guide bar structure: 1-0 / 1-2 / 1-0 / 1-2 / 4-5 / 4-3 / 4-5 / 4-3 / / , and the GB2 guide bar structure is: 4-5 / 4-3 / 4-5 / 4-3 / 1-0 / 1-2 / 1-0 / 1-2 / / , GB3 comb structure: 1-0 / 4-5 / / , By setting this pattern on the outer layer 21 of the knitted fabric, the strength and abrasion resistance of the fabric can be improved, avoiding frequent damage and pilling; By setting the woven base layer 22, the woven base layer 22 adopts a twill woven structure made of high light fastness colored yarn, which can improve the high light fastness performance of the warp-knitted automotive fabric.

[0025] The reinforcing layer 3 includes a glass fiber cloth layer 31, which is disposed on the lower surface of the woven base fabric layer 22. A high-temperature ceramic fiber woven layer 32 is disposed on the lower surface of the glass fiber cloth layer 31 and is connected to the upper surface of the wear-resistant inner layer 4. The glass fiber cloth layer 31, woven from glass fibers, possesses properties such as high-temperature tensile strength, low thermal shrinkage, anti-aging, and corrosion resistance. The high-temperature ceramic fiber woven layer 32, woven from high-temperature ceramic fibers, can withstand high temperature and pressure, and exhibits properties such as corrosion resistance, wear resistance, and thermal shock resistance. Therefore, the combined use of the glass fiber cloth layer 31 and the high-temperature ceramic fiber woven layer 32 effectively improves the overall structural strength of the warp-knitted automotive fabric.

An Oxford cloth layer 52 is disposed on the upper surface of the nylon fabric layer 51, and an ultra-high molecular weight polyethylene fiber fabric layer 53 is disposed on the upper surface of the Oxford cloth layer 52. The nylon fabric layer 51 provides high strength, good wear resistance, and excellent elasticity; the Oxford cloth layer 52 provides soft color, a soft fabric body, good breathability, good waterproofness, and good durability; and the ultra-high molecular weight polyethylene fiber fabric layer 53 provides extremely high strength and wear resistance, as well as low density and light weight. Therefore, the combined use of the nylon fabric layer 51, the Oxford cloth layer 52, and the ultra-high molecular weight polyethylene fiber fabric layer 53 improves the wear resistance of the outer surface of the warp-knitted automotive fabric.
