Description

Technical Field

[0001] This utility model belongs to the field of warp knitting fabric technology, and in particular relates to a breathable mesh fabric with an uneven surface. Background Technology

[0002] Three-dimensional spacer fabric (commonly known as 3D mesh / sandwich mesh) using double needle bed warp knitting technology has a three-layer structure of "mesh on the top and bottom + connecting monofilament in the middle", which can provide good breathability, resilience and cushioning, and is suitable for making sofa seats, backrests and various cushions (such as office chair cushions, car cushions and leisure cushions).

[0003] Currently, the thickness of warp-knitted mesh fabrics used in the production of sofa seats, backrests, and various cushions is generally preferred to be within the range of 5-15mm to ensure good support, resilience, high load-bearing capacity, and abrasion resistance. However, precisely because of this, its breathability and heat dissipation are weakened to some extent. Even if the fabric itself has mesh holes for heat dissipation, its heat dissipation capacity still cannot meet consumers' requirements in the hot summer. Utility Model Content

[0004] The purpose of this invention is to provide a breathable mesh fabric with an uneven surface. Through the weaving process, the surface of the fabric is made into an alternating uneven structure, which increases the contact gap between the user's skin and the fabric, thereby effectively improving the breathability and heat dissipation effect. At the same time, it also has an aesthetically pleasing uneven visual effect and enhances the quality of the fabric.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a breathable mesh fabric with an uneven surface, including a surface layer, a bottom layer, and connecting yarns that are padded on the surface layer and the bottom layer respectively and connect the surface layer and the bottom layer; the surface layer is formed by the padded yarns of the connecting yarns to form a raised area and a recessed area; the raised area and the recessed area are both rectangular grids, and the raised area and the recessed area are arranged alternately on the surface layer, with gaps between adjacent raised area and recessed area.

[0006] Furthermore, the breathable mesh fabric is a double-needle bed warp-knitted fabric, using six guide bars, namely GB1, GB2, GB3, GB4, GB5, and GB6; the surface layer is woven from guide bars GB1 and GB2; the bottom layer is woven from guide bars GB5 and GB6; the raised areas and recessed areas of the surface layer are formed by guide bars GB3 and GB4 padding yarn on the surface of the surface layer, respectively.

[0007] Furthermore,

[0008] The organizational structure of GB1 is: 1-0-0-0 / 1-2-2-2 / 2-3-3-3 / 2-1-1-1 / / , 1 through 1 empty;

[0009] The organizational structure of GB2 is: 2-3-3-3 / 2-1-1-1 / 1-0-0-0 / 1-2-2-2 / / , 1 through 1 empty;

[0010] The organizational structure of GB3 is: (0-1-0-1)*16 / 3-3-3-4 / 6-6-6-7 / (9-10-9-10)*16 / 6-6-6-7 / 3-3-3-4 / / , 9 through 9 empty;

[0011] The organizational structure of GB4 is: (0-1-0-1)*16 / 3-3-3-4 / 6-6-6-7 / (9-10-9-10)*16 / 6-6-6-7 / 3-3-3-4 / / , 10 empty spaces, 7 through spaces, 1 empty space;

[0012] The structure of GB5 is: 1-1-1-0 / 1-1-1-2 / / , fully penetrated;

[0013] The structure of GB6 is: 1-1-1-2 / 1-1-1-0 / / , fully penetrated;

[0014] In the GB3 weave structure, “(0-1-0-1)*16” and “(9-10-9-10)*16” have double-sided padding on both the top and bottom layers, forming a raised area on the top layer. In the GB4 weave structure, “(0-1-0-1)*16” and “(9-10-9-10)*16” have double-sided padding on both the top and bottom layers, forming a recessed area on the top layer. In the GB3 and GB4 weave structures, “3-3-3-4 / 6-6-6-7 / ” and “6-6-6-7 / 3-3-3-4” have single-sided padding only on the bottom layer, forming the gap area on the top layer.

[0015] Furthermore, the yarn used in GB3 is thicker than that used in GB4, which can further ensure that the raised area of ​​the surface layer is higher than the recessed area of ​​the surface layer.

[0016] Furthermore, the feed rate of GB3 is greater than that of GB4, which can further ensure that the raised area of ​​the surface layer is higher than the recessed area of ​​the surface layer.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] 1) The surface layer of this utility model forms a circular concave-convex structure, which increases the contact gap between the user's skin and the fabric, thereby effectively improving the breathability and heat dissipation effect.

[0019] 2) The present invention leaves a gap between the raised area and the recessed area of ​​the surface layer, which not only makes the boundary between the raised area and the recessed area clearer, but also improves the flexibility of the fabric, making the fabric easy to fold or bend in the gap area.

[0020] 3) The surface layer of this utility model presents a cyclical concave-convex structure, which is more visually appealing and enhances the quality of the fabric.

[0021] 4) GB3 and GB4 adopt a multi-speed warp feeding mode, which can adjust the warp feeding amount of GB3 and GB4. Through the padding structure of GB3 and GB4 on the surface layer, the yarn thickness of GB3 is greater than that of GB3, and the warp feeding amount of GB3 is greater than that of GB4, the synergy of these three factors makes the raised area and the recessed area of ​​the surface layer form a distinct uneven state.

[0028] Example:

[0029] A breathable mesh fabric with an uneven surface is woven by a double needle bed warp knitting machine and uses six guide bars, namely GB1, GB2, GB3, GB4, GB5 and GB6.

[0030] The breathable mesh fabric includes a surface layer 1, a bottom layer, and connecting yarns that padded the surface layer 1 and the bottom layer and connect the surface layer 1 and the bottom layer, respectively. The connecting yarns padded the surface layer 1 to form a raised area 2 and a recessed area 3; for example... Figure 1As shown, the raised area 2 and the recessed area 3 of the surface layer are formed by the yarn padding on the surface of the surface layer 1 by the comb GB3 and comb GB4, respectively; the raised area 2 and the recessed area 3 of the surface layer are both rectangular grids, and the raised area 2 and the recessed area 3 of the surface layer are arranged alternately on the surface layer 1, and there is a gap area A between adjacent raised area 2 and recessed area 3; the surface layer 1 is woven by comb GB1 and comb GB2; the bottom layer is woven by comb GB5 and comb GB6.

[0031] like Figures 2-4 As shown:

[0032] GB1's organizational structure: 1-0-0-0 / 1-2-2-2 / 2-3-3-3 / 2-1-1-1 / / , 1 through 1 empty;

[0035] GB4's organizational structure: (0-1-0-1)*16 / 3-3-3-4 / 6-6-6-7 / (9-10-9-10)*16 / 6-6-6-7 / 3-3-3-4 / / , 10 spaces, 7 through spaces, 1 space;

[0037] GB6's organizational structure: 1-1-1-2 / 1-1-1-0 / / , fully penetrated.

[0038] The yarns used in each comb are as follows: GB1 and GB2 use 75D / 36F DTY (DTY is polyester low elastic yarn); GB3 uses 300D / 96F DTY recycled yarn (DTY recycled yarn is recycled polyester low elastic yarn); GB4 uses 75D elastic yarn (75D elastic yarn is P75+40 spandex covered yarn); GB5 and GB6 use 66D / 24F FDY (FDY is fully drawn yarn).

[0039] like Figures 1-4As shown, in the GB3 weave structure, “(0-1-0-1)*16” and “(9-10-9-10)*16” are double-sided padded with yarn on both the top layer 1 and the bottom layer, forming a raised area 2 on the top layer 1; in the GB4 weave structure, “(0-1-0-1)*16” and “(9-10-9-10)*16” are double-sided padded with yarn on both the top layer 1 and the bottom layer, forming a recessed area 3 on the top layer 1; in the GB3 and GB4 weave structures, “3-3-3-4 / 6-6-6-7 / ” and “6-6-6-7 / 3-3-3-4” are only padded with yarn on one side on the bottom layer, that is, a gap area A is formed on the top layer 1 (the gap area A not only makes the boundary between the raised area 2 and the recessed area 3 clearer, but also improves the flexibility of the fabric, making the fabric easy to fold or bend at the gap area A).
