[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1-4 As shown, a breathable composite fabric, the basic layer 100 is woven by a first inlay yarn 400 and a second inlay yarn 500, the first inlay yarn 400 is ultrafine fiber, the second inlay yarn 500 is cotton fiber, and the first inlay yarn 400 and the second inlay yarn 500 are both 1 through 1 hole when threading. In this embodiment, referring to Figure 3, the longitudinal direction is 4 wales as a cycle, and the transverse direction is 6 rows as a cycle. The starting points of the first inlay yarn 400 are located at wale 1 and wale 3 respectively. When the first inlay yarn 400 takes wale 1 as the starting point, the first inlay yarn 400 passes through wale 1, wale 2, and wale 3. When the first inlay yarn 400 takes wale 3 as the starting point, the first inlay yarn 400 passes through wale 3, wale 4, and wale 1. Therefore, when the first inlay yarn 400 makes an inlay yarn movement between wale 1 and wale 2, the first three rows of rows 10, 11, and 12 are woven, and the last three rows of rows 13, 14, and 15 are not woven. When the first inlay yarn 400 makes an inlay yarn movement between wale 2 and wale 3, the rows The first three rows of row 10, row 11 and row 12 are not woven, and the last three rows of row 13, row 14 and row 15 are woven. When the first inlay yarn 400 makes an inlay yarn movement between wales 3 and wales 4, the first three rows of row 10, row 11 and row 12 are woven, and the last three rows of row 13, row 14 and row 15 are not woven. When the first inlay yarn 400 makes an inlay yarn movement between wales 4 and wales 1, the first three rows of row 10, row 11 and row 12 are not woven, and the last three rows of row 13, row 14 and row 15 are woven. Therefore, when the first inlay yarn 400 makes an inlay yarn movement between the four wales, its inlay yarn movement trajectory is cross-configured.
[0019] However, the wales cannot be separated continuously, and the first three rows need to be woven and connected with the last three rows. Therefore, the last row among rows 10, 11, and 12, namely row 12, is taken, and the first row among rows 13, 14, and 15, namely row 13, is taken, and the two perform inlay movement, because in the first three rows, there is inlay movement between wales 1 and wales 2, and there is inlay movement between wales 3 and wales 4, while in the last three rows, there is no inlay movement between wales 1 and wales 2, and there is no inlay movement between wales 3 and wales 4. In the first three rows, there is no inlay movement between wales 2 and wales 3, and there is no inlay movement between wales 4 and wales 1. In the last three rows, there is inlay movement between wales 2 and wales 3, and there is inlay movement between wales 4 and wales 1. There is inlay movement, so when the first inlay 400 moves to row 12, it cannot connect the adjacent points between row 12 and row 13, so it will be connected with the inlay movement between the cross-arranged wales 2 and wales 3, and the inlay movement between wales 4 and wales 1. When the first inlay 400 moves to row 15, it cannot connect the adjacent points between row 15 and row 10, so it will be connected with the inlay movement between the cross-arranged wales 1 and wales 2, and the inlay movement between wales 3 and wales 4. This cycle is repeated so that the wales will not be separated. Therefore, the inlay movement trajectory of the first inlay 400 is 1-2 / 2-1 / 1-3 / 3-2 / 2-3 / 3-1 and 3-4 / 4-3 / 3-1 / 1-4 / 4-1 / 1-3.
[0020] The starting points of the second yarn inlay 500 are located at wale 2 and wale 4, respectively. Figure 4 , when the second inlay yarn 500 takes wale 2 as the starting point, the second inlay yarn 500 passes through wale 2, wale 1, and wale 4. When the second inlay yarn 500 takes wale 4 as the starting point, the second inlay yarn 500 passes through wale 4, wale 3, and wale 2. Therefore, when the second inlay yarn 500 makes an inlay movement between wales 1 and wale 2, the first three rows of rows 10, 11, and 12 are woven, and the last three rows of rows 13, 14, and 15 are not woven. When the second inlay yarn 500 makes an inlay movement between wale 2 and wale 3, the first three rows of rows 10, 11, and 12 are not woven, and row 1 When the second inlay yarn 500 makes an inlay movement between wales 3 and 4, the first three rows of rows 10, 11 and 12 are woven, and the last three rows of rows 13, 14 and 15 are not woven. When the second inlay yarn 500 makes an inlay movement between wales 4 and 1, the first three rows of rows 10, 11 and 12 are not woven, and the last three rows of rows 13, 14 and 15 are woven. Therefore, when the second inlay yarn 500 makes an inlay movement between the four wales, its inlay movement trajectory is cross-configured.
[0021] However, the wales cannot be separated continuously, and the first three rows need to be woven and connected with the last three rows. Therefore, the last row among rows 10, 11, and 12, namely row 12, is taken, and the first row among rows 13, 14, and 15, namely row 13, is taken, and the two perform inlay movement, because in the first three rows, there is inlay movement between wales 1 and wales 2, and there is inlay movement between wales 3 and wales 4, while in the last three rows, there is no inlay movement between wales 1 and wales 2, and there is no inlay movement between wales 3 and wales 4. In the first three rows, there is no inlay movement between wales 2 and wales 3, and there is no inlay movement between wales 4 and wales 1. In the last three rows, there is inlay movement between wales 2 and wales 3, and there is inlay movement between wales 4 and wales 1. There is inlay movement, so when the second inlay 500 moves to row 12, it cannot connect the adjacent points between row 12 and row 13, so it will be connected with the inlay movement between the cross-arranged wales 2 and wales 3, and the inlay movement between wales 4 and wales 1. When the second inlay 500 moves to row 15, it cannot connect the adjacent points between row 15 and row 10, so it will be connected with the inlay movement between the cross-arranged wales 1 and wales 2, and the inlay movement between wales 3 and wales 4. This cycle is repeated so that the wales will not be separated. Therefore, the inlay movement trajectory of the second inlay 500 is 2-1 / 1-2 / 2-4 / 4-1 / 1-4 / 4-2 and 4-3 / 3-4 / 4-2 / 2-3 / 3-2 / 2-4.
[0022] Because the inlay movement trajectory of the first inlay yarn 400 is 1-2 / 2-1 / 1-3 / 3-2 / 2-3 / 3-1 and 3-4 / 4-3 / 3-1 / 1-4 / 4-1 / 1-3, and the inlay movement trajectory of the second inlay yarn 500 is 2-1 / 1-2 / 2-4 / 4-1 / 1-4 / 4-2 and 4-3 / 3-4 / 4-2 / 2-3 / 3-2 / 2-4, refer to Figure 2 Therefore, there is a movement of the yarn between the rows 10, 11, and 12 of wales 1 and 2, so an extension line will be formed. Similarly, there are extension lines between the rows 13, 14, and 15 of wales 2 and 3, and there are extension lines between rows 12 and 13. Therefore, the wales with extension lines will gather together, and the wales without extension will separate. The wales without gathering will form a mesh, and the gathered wales will form the edge of the mesh. Figure 2 As shown, a hexagonal mesh 600 is formed, and two adjacent meshes 600 are cross-arranged.
[0023] Therefore, the base fabric layer 100 will form a hexagonal mesh structure, and the existence of the mesh 600 can allow the air in the fabric to flow freely, and the mesh structure is relatively sparse, so when the user wears it, the generated hot air can enter and circulate through the mesh in the fabric, so that the fabric can achieve the effect of fast heat dissipation and not easy to get stuffy, so that the fabric has good breathability and can keep dry continuously, and the sparse mesh structure not only improves the comfort of the fabric, but also makes the fabric lighter and softer.
[0024] The first pad yarn 400 of the base fabric layer 100 is a superfine fiber of 35dtex / 48F-60dtex / 48F, and the second pad yarn 500 is a cotton fiber of 50-75 ne. In the present embodiment, the yarn count of the first pad yarn 400 is a superfine fiber of 50dtex / 48F, and the yarn count of the second pad yarn 500 is a cotton fiber of 60 ne. The longitudinal density of the base fabric layer 100 is 13.5 cpc, and the transverse density is 16 wpi. The single filament of the superfine fiber is fine, and the fiber has capillary voids. As a natural fiber, cotton fiber is relatively skin-friendly. Therefore, after being woven into a mesh structure with a longitudinal density of 13.5 cpc and a transverse density of 16 wpi, the gram weight of the fabric is between 78g / m^2-100g / m^2, making the fabric relatively light and thin, and the formed mesh holes are more conducive to air circulation, thereby making the fabric more breathable.
[0025] The leather layer 300 is made of PU leather, which has excellent waterproof properties and is relatively light. As an environmentally friendly material, PU leather, after being softened, can not only reduce the weight of the overall fabric when worn by the user, but also increase the softness of the overall fabric without causing skin irritation.
[0026] The bonding layer 200 is a bonding layer, which is made of ultrafine fibers and polyurethane through composite spinning. The filaments are laid into a mesh, and the fiber mesh is then thermally bonded to form a double-sided bonded non-woven fabric without a weaving process, thereby forming a fibrous non-woven fabric with micropores on the surface. The fibrous non-woven fabric feels lighter and softer, and the presence of micropores makes the fabric more breathable.
[0027] The adhesive layer 200 is heat-pressed to simultaneously bond the base fabric layer 100 and the leather layer 300 to form a composite fabric, the overall weight of which is 200g / m^2-250g / m^2. When the user wears it, the leather layer 2 is not tightly fitted to the human skin. Therefore, when worn, the hot air generated between the leather layer 300 and the skin will pass through the mesh holes of the base fabric layer 100, and the mesh holes allow air to flow freely. Therefore, after the hot air flows through the mesh holes, it flows through the air in the place that is not in contact with the skin, thereby discharging the generated hot air. Therefore, when wearing the leather, the human body remains continuously dry and comfortable, without increasing the feeling of stuffiness, and the composite fabric is relatively thin, so the user will not feel heavy when wearing it.
[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
