Description

Technical Field

[0001] This utility model belongs to the field of seat fabric technology, and in particular relates to a thickened and warm car seat fabric. Background Technology

[0002] In the automotive industry, the performance of seat fabrics has a significant impact on the driving and riding experience. As people's demands for automotive comfort continue to increase, especially during cold seasons, the warmth retention performance of seats has become a key focus for consumers.

[0003] Currently, common car seat fabrics on the market mainly suffer from the following problems. On the one hand, some traditional seat fabrics rely on a single material, such as ordinary textiles or leather, resulting in limited warmth retention and making it difficult to provide sufficient warmth for drivers and passengers in cold weather. On the other hand, some fabrics with certain warmth retention functions often fall short in terms of breathability, durability, and aesthetics. For example, while some thicker warm fabrics can improve warmth retention, their poor breathability can easily make drivers and passengers feel stuffy and uncomfortable; while some fabrics that emphasize aesthetics and durability may fail to achieve ideal warmth retention due to structural or material limitations.

[0004] In addition, existing seat fabrics have a relatively simple structural design and lack innovative structures to comprehensively improve various performance aspects.

[0005] Therefore, it is essential to invent a thicker, warmer car seat fabric. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a thickened and warm car seat fabric, including a blended base fabric, a backing layer, a warming interlayer, a leather fabric layer, stitching lines, pile openings, and fabric pile. The blended base fabric has the fabric pile and is located between the warming interlayer and the leather fabric layer. Numerous stitching lines sew the blended base fabric, backing layer, warming interlayer, and leather fabric layer together. Both the warming interlayer and the leather fabric layer are provided with pile openings.

[0007] Preferably, the blended base fabric is combined with the backing layer and the thermal insulation layer, and the thermal insulation layer is combined with the leather fabric layer. The thickness of the backing layer is greater than the thickness of the blended base fabric, the thermal insulation layer and the leather fabric layer.

[0008] Preferably, the density of the fleece pores in the insulating interlayer and the leather fabric layer is not less than ten per square centimeter.

[0009] Preferably, the stitching avoids the loopholes in the pile when stitching the blended base fabric, backing layer, thermal insulation layer, and leather fabric layer together.

[0010] Preferably, the fabric pile of the blended base fabric is exposed through pile holes, and the fabric pile is long pile.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention employs a blended base fabric combined with an insulating interlayer. The long fibers of the blended base fabric itself have excellent heat retention properties, capable of trapping a large amount of air to form an insulating layer. The insulating interlayer further enhances the heat retention effect. Together, the two effectively reduce heat loss, providing a warm and comfortable riding experience for passengers in cold weather.

[0013] Both the insulating interlayer and the leather fabric layer of this invention are provided with a density of no less than ten pile holes per square centimeter. These holes not only allow the long pile of the blended base fabric to pass through, but also provide channels for air circulation. Air can circulate inside the fabric, carrying away moisture and heat, avoiding discomfort caused by stuffiness and dampness, and effectively improving the breathability of the seat.

[0014] This invention uses numerous stitches to sew the blended base fabric, backing layer, thermal insulation layer, and leather fabric layer together, ensuring a tight bond between the layers and forming a unified whole. This robust structural design effectively prevents shifting and separation between the layers, extending the fabric's lifespan. Furthermore, the backing layer is thicker than the other three layers, further enhancing the overall strength and stability of the fabric. Attached Figure Description

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a thickened and warm car seat fabric, comprising a blended base fabric 1, a backing layer 2, a warming interlayer 3, a leather fabric layer 4, stitching threads 5, pile openings 6, and fabric pile 7. The blended base fabric 1 has the fabric pile 7 and is located between the warming interlayer 3 and the leather fabric layer 4. Numerous stitching threads 5 sew the blended base fabric 1, the backing layer 2, the warming interlayer 3, and the leather fabric layer 4 together. Both the warming interlayer 3 and the leather fabric layer 4 are provided with pile openings 6.

[0024] Furthermore, the blended base fabric 1, backing layer 2, and thermal insulation layer 3 are bonded together using a hot-melt adhesive process to form the underlying structure. Backing layer 2 utilizes 8mm thick polyurethane high-elasticity sponge with a Shore A hardness of 30A, providing both cushioning and support. This layer's thickness exceeds the total thickness (3.3mm) of the blended base fabric 1 (0.5mm wool-acrylic blend), thermal insulation layer 3 (2mm aerogel insulation), and leather fabric layer 4 (0.8mm microfiber leather) by 1.4 times. The edges of backing layer 2 are seamlessly connected to the other three layers using ultrasonic welding, forming a stable base support structure that effectively disperses the pressure stress on the seat, preventing the fabric from collapsing or deforming due to long-term use.

[0025] Furthermore, both the thermal insulation layer 3 and the leather fabric layer 4 are laser-cut with 1.2mm diameter circular perforations 6, distributed at a density of 12 per square centimeter. During the lamination process, the perforations in the thermal insulation layer 3 and the leather fabric layer 4 are precisely aligned, and the edges of the perforations in the two layers are fused and reinforced by a hot press roller under a pressure of 0.4MPa. The inner walls of the perforations in the leather fabric layer 4 are beveled to form a 15° chamfer to prevent snagging when the fabric fibers 7 puncture. This high-density perforation array ensures both the penetration rate of the fabric fibers 7 and maintains the structural strength of the leather layer. Tensile testing verified that the tensile strength of the perforated area is still 85% of that of the non-perforated area.

[0026] Furthermore, 40D nylon high-strength stitching thread 5 is used for the four-layer structure stitching, with the stitching path and the fleece openings 6 staggered by 3mm. The stitching thread 5 uses a double-needle chain stitch technique to pass through the backing layer 2, the thermal insulation layer 3, and the blended base fabric 1, forming a hidden flat seam on the surface of the leather fabric layer 4. Each section of the stitch is reinforced with backstitches at both ends, with the stitch length controlled at 3mm to ensure a stitch strength of 15N / 5cm. This design prevents the stitching thread from clogging the openings and affecting the fleece 7's passage, while also creating elastic seam nodes at fabric bends, improving overall durability.

[0027] Furthermore, the blended base fabric 1 is made of 38mm extra-long wool fibers blended with acrylic fibers, and the pile height 7 is achieved to 12mm through a napping process. During the lamination process, the temperature gradient is controlled by a customized pressing equipment (80℃ for the leather surface and 60℃ for the blended surface), allowing the pile 7 to naturally penetrate the pile holes 6 in the semi-cured state of the hot melt adhesive. The ends of the penetrated pile 7 are then subjected to low-temperature shaping treatment to form an outward-curling umbrella-like structure, which not only enhances the visual layering but also prevents the pile from falling off through the interlocking of the fibers. After abrasion resistance testing, the pile penetration area still retains more than 90% of its pile integrity after 5000 cycles of friction.

[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
