Description

Technical Field

[0001] This invention relates to the field of automotive interior fabric technology, and more particularly to a recycled fiber automotive seat fabric. Background Technology

[0002] Automotive seat fabrics typically cover the exterior of the seat foam, forming the seat surface that comes into direct contact with occupants. As automotive interior materials move towards low-carbon and resource-recycling principles, recycled polyester and nylon fibers, made from recycled materials such as waste textiles and plastic bottles, are increasingly being used in automotive seat fabrics.

[0003] Existing recycled fiber automotive seat fabrics typically employ a structure where the fabric layer and the sponge layer are directly composited. During extended periods of sitting, air circulation between the fabric and sponge layers is limited, leading to heat and moisture buildup in the contact area between the passenger and the seat. Simultaneously, the ordinary sponge layer is prone to localized compression deformation after repeated pressure, causing indentations or wrinkles on the fabric surface. Therefore, there is a need for a recycled fiber automotive seat fabric that combines elastic support with airflow. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a recycled fiber automotive seat fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recycled fiber automotive seat fabric includes a recycled fiber fabric layer, on one side of which an elastic spacer layer and a base fabric layer are sequentially laminated. The recycled fiber fabric layer has multiple air vents. The elastic spacer layer includes multiple elastic support strips extending along the fabric length and spaced apart, with an air channel formed between adjacent elastic support strips. The air vents are connected to the air channel. The base fabric layer has multiple transverse air grooves on the side facing the elastic spacer layer, and these transverse air grooves are connected to the multiple air channels. Each elastic support strip includes multiple alternately connected first support segments and second support segments. The first support segments are inclined towards and connected to the recycled fiber fabric layer, and the second support segments are inclined towards and connected to the base fabric layer.

[0007] Preferably, the first support segment and the second support segment are continuously and alternately arranged along the extension direction of the elastic support strip, so that the elastic support strip has a corrugated structure.

[0008] Preferably, the first support segment of two adjacent elastic support strips is staggered along the length of the fabric.

[0009] Preferably, the plurality of vent holes are arranged in multiple columns, and each column of vent holes corresponds to an air guiding channel.

[0010] Preferably, the plurality of transverse air guide grooves are spaced apart along the length of the fabric, and the transverse air guide grooves and air guide channels intersect each other.

[0011] Preferably, the base fabric layer has multiple anti-slip protrusions on the side opposite to the elastic spacer layer.

[0012] Preferably, the edges of the regenerated fiber fabric layer, the elastic spacer layer, and the base fabric layer are all connected by a binding strip.

[0013] Preferably, the end of the air guide channel extends to the edge strip, and the edge strip is provided with a lateral exhaust port that communicates with the air guide channel.

[0014] Preferably, the recycled fiber fabric layer is formed by interlacing recycled polyester fiber yarn and recycled nylon fiber yarn.

[0015] Preferably, the elastic support strip is a strip structure woven from elastic polyester monofilaments, and the base fabric layer is a recycled polyester fiber woven layer.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention incorporates an elastic spacer layer between the recycled fiber fabric layer and the base fabric layer, and utilizes spaced elastic support strips to form multiple air channels. When an occupant sits down or changes their posture, the elastic support strips deform under pressure, compressing the air within the air channels and causing it to flow between the vents, air channels, transverse air grooves, and side exhaust ports, thereby improving the ventilation and heat dissipation effect of the seat contact area.

[0018] 2. The elastic support strip consists of alternating inclined first and second support sections, providing elastic support in the fabric thickness direction. The staggered arrangement of the first support sections in adjacent elastic support strips can disperse the pressure applied by the occupant, reduce the possibility of excessive concentration of local support points, and improve the fabric's recovery ability after repeated compression.

[0019] 3. The recycled fiber fabric layer and the base fabric layer are made of recycled fibers, which can improve the utilization rate of recycled materials in automotive seat fabrics; the anti-slip bumps on the outside of the base fabric layer can increase the friction between the fabric and the seat foam, and reduce relative slippage during fabric assembly and use.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In the description of this invention, 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 this invention 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.

[0027] Reference Figures 1 to 4 A recycled fiber automotive seat fabric includes a recycled fiber fabric layer 1, an elastic spacer layer 2, and a base fabric layer 3, which are sequentially composited from the outside to the inside. The recycled fiber fabric layer 1 forms the exterior surface and human contact surface of the automotive seat, the base fabric layer 3 is used to connect with the foam or padding of the automotive seat, and the elastic spacer layer 2 forms an elastic support space between the recycled fiber fabric layer 1 and the base fabric layer 3.

[0028] The recycled fiber fabric layer 1 is formed by interlacing recycled polyester fiber yarn and recycled nylon fiber yarn. The recycled polyester fiber yarn can be used as the warp yarn, and the recycled nylon fiber yarn can be used as the weft yarn, so as to take into account the dimensional stability, abrasion resistance and flexibility of the fabric layer. The recycled fiber fabric layer 1 is provided with multiple ventilation holes 4, which can be formed by the mesh reserved during the weaving process, thereby avoiding yarn breakage caused by punching holes later.

[0029] The elastic spacer layer 2 includes multiple parallel and spaced-apart elastic support strips 5 extending along the length of the fabric. A gap is maintained between adjacent elastic support strips 5, forming an air channel 6. The multiple air channels 6 are arranged along the width of the fabric to allow air to flow longitudinally along the car seat.

[0030] Each elastic support strip 5 includes a first support segment and a second support segment that are continuously and alternately connected. The first support segment is inclined toward and connected to the regenerated fiber fabric layer 1, and the second support segment is inclined toward and connected to the base fabric layer 3, so that the elastic support strip 5 forms a corrugated structure in the longitudinal section of the fabric.

[0031] The elastic support strip 5 can be woven from elastic polyester monofilaments. When the first support section and the second support section are subjected to vertical pressure, they can bend elastically in the inclined direction. After the pressure is released, they recover by their own elasticity, thereby providing continuous support for the regenerated fiber fabric layer 1.

[0032] The first support segments of two adjacent elastic support strips 5 are staggered along the length of the fabric, so that the upper support positions of different elastic support strips 5 are not located on the same horizontal straight line. This staggered structure can distribute the pressure among multiple support positions, reducing the possibility of continuous creases in the regenerated fiber fabric layer 1.

[0033] Multiple vents 4 are arranged in multiple rows, with each row of vents 4 located above and connected to an air guide channel 6. When the human body comes into contact with the regenerated fiber fabric layer 1, air in the contact area can enter the air guide channel 6 through the vents 4; when the elastic support strip 5 is compressed, the local volume of the air guide channel 6 decreases, causing air to flow along the air guide channel 6.

[0034] Multiple transverse air guide grooves 7 are provided on the side of the base fabric layer 3 facing the elastic spacer layer 2. The transverse air guide grooves 7 extend along the width of the fabric and intersect and communicate with multiple longitudinally arranged air guide channels 6. When some air guide channels 6 are compressed by the occupant's body, air can be transferred through the transverse air guide grooves 7 to the uncompressed air guide channels 6, preventing air from flowing only in one direction.

[0035] The edges of the regenerated fiber fabric layer 1, the elastic spacer layer 2, and the base fabric layer 3 are connected by a binding strip 9. The binding strip 9 is used to prevent the edges of the three-layer structure from separating and to cover the interlayer connection points. The end of the air guide channel 6 extends to the binding strip 9, and the binding strip 9 is provided with a lateral exhaust port 10 that communicates with the air guide channel 6, so that some air in the air guide channel 6 can be discharged from the side of the fabric.

[0036] Multiple anti-slip protrusions 8 are provided on the side of the base fabric layer 3 facing away from the elastic spacer layer 2. The anti-slip protrusions 8 can be formed by curing dot-shaped hot melt adhesive or by weaving them integrally with the base fabric layer 3. After the fabric is wrapped around the outside of the car seat foam, the anti-slip protrusions 8 come into contact with the surface of the foam to increase the friction between the two.

[0037] During use, when an occupant sits in the car seat, the regenerated fiber fabric layer 1 transmits pressure to the elastic support strip 5. The first and second support sections are compressed and undergo elastic bending, reducing the local volume of the air duct 6. The air in the air duct 6 flows to the vent hole 4, the transverse air duct groove 7, and the side exhaust port 10, respectively.

[0038] When the occupant changes their sitting posture or leaves the seat, the first and second support sections return to their original shapes, the volume of the air passage 6 increases, and external air re-enters the air passage 6 through the vent 4 and the side exhaust port 10. Through repeated compression and recovery, a passive ventilation process is formed, thereby improving the airflow inside the car seat fabric.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
