Description

Technical Field

[0001] The invention relates to the field of automobile ventilated seats, and in particular to a warp-knitted spacer fabric with large ventilation volume and stable structure. Background Art

[0002] ‌Car ventilated seats are a type of car configuration that increases the air circulation between the seat surface and the passengers to improve riding comfort. ‌The principle of car ventilated seats mainly relies on adding fans to the back of the seat cushion and the back of the backrest foam. The fan is used to suck in the air and then guide it into the ventilation layer. The air then penetrates upward from the surface of the ventilation layer through the heating pad to the surface of the seat cover (the seat cover is usually made of perforated leather), thereby realizing the function of seat ventilation. This ventilation function allows air circulation, helps dissipate sweat from the buttocks and back, and brings comfort to passengers, especially in hot weather. The design of ventilated seats is to improve the air circulation environment of the part where the human body contacts the seat surface, so that the contact surface between the body and the seat can remain dry and comfortable even for a long time. This configuration usually has two types: blowing type and negative pressure suction type, which take away the heat from the seat surface in different ways to improve riding comfort. ‌ As the name suggests, a car ventilated seat is a seat that can be ventilated. However, the existing warp knitted spacer fabric has too much longitudinal and lateral extensibility, which will lead to dimensional changes. It is easy to tilt left and right in the thickness direction, resulting in pressure drop and collapse. Specifically, there are the following problems: first, the current warp knitted spacer fabric has insufficient ventilation. Second, the mesh structure of the current warp knitted spacer fabric has too much longitudinal and lateral extensibility, is structurally unstable, and changes in size. Third, in order to increase the ventilation volume, traditional technology usually adopts a hole-to-hole process for the upper and lower layers, and a vertical support process for the middle layer, which results in the spacer layer being unable to provide a very stable support effect, which in turn leads to tilting left and right and collapse. Therefore, a warp knitted spacer fabric with large ventilation volume and stable structure is needed to solve the above problems. Summary of the invention

[0003] The purpose of the embodiments of the present invention is to provide a warp-knitted spacer fabric with large ventilation volume and stable structure, so as to solve the problem of insufficient ventilation volume and pressure of automobile ventilated seats.

[0004] An embodiment of the present invention is implemented as follows: a warp-knitted spacer fabric with large ventilation volume and stable structure includes: an upper layer and a lower layer, wherein the upper layer and the lower layer adopt a mesh structure with a hole diameter of 5-30 mm for increasing ventilation volume; a spacer layer, which is arranged between the upper layer and the lower layer for supporting the upper layer and the lower layer.

[0005] Preferably, the upper and lower layers are made of 150-2000D industrial high-strength polyester yarn.

[0006] Preferably, the spacer layer is supported by an X- or V-shaped structure with a triangular cross-section, so as to increase the stability of the upper and lower layers.

[0007] Preferably, resin or polyurethane additives are provided on the upper and lower layers to reinforce the warp-knitted spacer fabrics on the upper and lower layers.

[0008] The warp knitted spacer fabric with large ventilation volume and stable structure provided by the present invention has large and tight coil fastness of the upper layer and the lower layer, which increases the stability of the warp knitted spacer fabric. The spacer layer is supported by an X or V-shaped structure, which increases the stability of the structure. The fastness of the warp knitted spacer fabric can be further enhanced by further using resin or polyurethane additives, and the practicality is strong. BRIEF DESCRIPTION OF THE DRAWINGS
