Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, specifically to an imitation suede fabric. Background Technology

[0002] In automotive interiors and high-end furniture, faux suede fabric is highly favored for its luxurious appearance and comfortable feel.

[0003] To improve the breathability of products, perforations are often made in the fabric. However, in actual use, especially when used as a covering material for car door panels, the perforations of existing single-layer perforated faux suede fabrics disrupt the fiber continuity of the fabric, creating stress concentration points at the edges of the holes. Under the repeated friction and stretching during daily use, the stress concentration causes the fibers to loosen and fall off from the edges, leading to irreversible enlargement of the openings and eventually tearing along the perforation line, thus affecting the service life.

[0004] To address the above issues, a faux suede fabric is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a faux suede fabric.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a faux suede fabric, comprising a top layer, a filling layer, and a bottom layer stacked sequentially from top to bottom, wherein the filling layer is a flexible porous material layer, and the top layer and the bottom layer are both faux suede fabric layers, and both have several rows of parallel and staggered openings, and the top layer has a hot stamping area around the openings by hot stamping.

[0007] The present invention is further configured such that: the surface layer is sewn close to the bottom layer by several quilting threads with several rows of openings in parallel, and the quilting threads are sewn on both sides of each row of openings.

[0008] The present invention is further configured such that the openings on the surface layer and the openings on the bottom layer overlap in vertical projection.

[0009] The present invention is further configured such that the openings on the surface layer and the bottom layer are staggered, and the diameter of the openings located at the staggered points is 1.5 to 3 times the diameter of the openings at the non-staggered points.

[0010] The present invention is further configured such that the filling layer is a sponge.

[0011] The present invention is further configured such that the surface layer, the filling layer and the bottom layer are bonded together by adhesive or hot pressing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] A type of faux suede fabric, such as Figure 1 as well as Figure 2 As shown, the structure includes a top layer 1, a filling layer 2, and a bottom layer 3 stacked sequentially from top to bottom. The filling layer 2 is a flexible porous material layer. The top layer 1 and the bottom layer 3 are both imitation suede fabric layers woven from specific raw materials and specifications, with a knitted plain weave structure. The three layers are bonded together by adhesive or hot pressing to form a stable multi-layer structure. In this embodiment, the imitation suede fabric used in the top layer 1 and the bottom layer 3 is composed of 90% polyester and 10% spandex. This ratio ensures that the fabric has both the strength and abrasion resistance of polyester and the excellent elasticity of spandex, which is the key to resisting deformation from repeated stretching. Its specifications are 40D*105D, woven by a water-jet loom. This weaving method makes the fabric structure uniform and the surface flat. The finished fabric has a width of 57 / 58 inches and a weight of 180g / m². This structural design aims to improve the breathability and durability of the fabric, and is especially suitable for high-frequency use scenarios such as automotive door panel wrapping. The surface layer 1 is made of imitation suede fabric with the above-mentioned raw materials and specifications, with a thickness of 0.5-1.0mm. Several rows of parallel and staggered openings 5 ​​are provided on the surface layer 1. The diameter of the openings 5 ​​is 0.5-2.0mm. A hot stamping area 4 is provided around the openings 5. The hot stamping area 4 is fixed by hot stamping process. Its material is electroplated aluminum foil, with a width of 0.5-1.0mm. The hot stamping area 4 not only enhances the appearance, but also strengthens the edge of the openings 5 ​​through thermosetting and prevents the fibers from loosening. The filling layer 2 is a flexible porous material layer. In this embodiment, sponge is used, with a thickness of 2-5mm. The density of the sponge is 20-40kg / m³, and the porosity is 70-90%. The filling layer 2 provides cushioning and breathability. Its porous structure allows air to flow between layers, improving the overall breathability. The bottom layer 3 also uses the above-mentioned 90% polyester + 10% spandex imitation suede fabric with a specification of 40D*105D and a thickness of 0.5-1.0mm. The bottom layer 3 has several rows of parallel and staggered openings 5. The diameter of the openings 5 ​​is the same as that of the top layer 1, which is 0.5-2.0mm. The openings 5 ​​of the top layer 1 and the bottom layer 3 overlap in the vertical projection. That is, when viewed from the top of the fabric, the openings 5 ​​of the top layer 1 and the openings 5 ​​of the bottom layer 3 are completely aligned, with an overlap error of less than 0.2mm. This overlapping design ensures smooth airflow and avoids local blockage. The openings 5 ​​on both the surface layer 1 and the bottom layer 3 are staggered, forming a honeycomb-like structure. The row spacing of the openings 5 ​​is 3-6 mm, and the column spacing is 2-4 mm. At the staggered points, the diameter of the opening 5 increases to 1.5 to 3 times the diameter of the openings 5 ​​at the non-staggered points. In this embodiment, 2 times is preferred. For example, the diameter of the openings 5 ​​at the non-staggered points is 1.0 mm, and the diameter of the openings 5 ​​at the staggered points is 2.0 mm. This design disperses stress concentration, especially in areas of frequent friction, and prevents the openings 5 ​​from enlarging. The surface layer 1 is sewn close to the bottom layer 3 by several quilting threads 6 with several rows of parallel openings 5. The quilting threads 6 are made of high-strength polyester thread with a diameter of 0.1-0.3mm and a stitching spacing of 5-10mm. The quilting threads 6 are sewn on both sides of each row of openings 5, 1-2mm away from the edge of the openings 5, forming a reinforcing band. The stitching depth penetrates the filling layer 2, but does not completely penetrate the bottom layer 3, to ensure the integrity of the bottom layer 3. The quilting threads 6 not only enhance the interlayer bonding, but also further disperse stress and prevent the fibers from falling off the edges of the openings 5.

[0018] Composite method: The surface layer 1, the filler layer 2 and the bottom layer 3 are bonded together by adhesive or hot pressing. In this embodiment, hot pressing is preferred. The parameters are: temperature 100-150°C, pressure 0.5-1.0MPa and time 10-20 seconds. These composite parameters match the material characteristics of the surface layer 1 and the bottom layer 3, which can achieve a strong bond without causing the spandex elasticity to fail. If adhesive is used, polyurethane adhesive can be used, and the coating amount is 20-40g / m².

[0019] Operating procedure: In the manufacturing process, the imitation suede fabric is first cut into surface layer 1 and bottom layer 3 according to the size. Then, the surface layer 1 and bottom layer 3 are punched with laser or precision mechanical molds to ensure that the openings 5 ​​are staggered and the diameter meets the requirements. Next, electroplated aluminum foil is applied around the openings 5 ​​of the surface layer 1 to form a hot stamping area 4. Then, the sponge of the filling layer 2 is placed on the bottom layer 3, and the prepared surface layer 1 is covered. The quilting is then stitched with quilting thread 6 using a quilting machine. Finally, it is bonded together by hot pressing or adhesive bonding. The entire process is carried out continuously to ensure that the fabric is flat and wrinkle-free.
