the air permeable area comprises air permeable tissues arranged at intervals, and a plane tissue is arranged between two adjacent air permeable tissues;
the air permeable tissue includes one or more holes penetrating the upper and lower surfaces of the hollow unit to form a passage for air convection.
3. Sandwich fabric according to claim 2, wherein the upper dial of the air-permeable zone needle tracks of the hollow cells are looped and the lower cylinder needles form one or more continuous float cells and/or one or more continuous loop cells.
4. The sandwich fabric according to claim 1, wherein the upper surface of the hollow unit is provided with planar areas arranged at intervals, and a breathable area is arranged between two adjacent planar areas;
the air permeable area comprises air permeable tissues arranged at intervals, and a plane tissue is arranged between two adjacent air permeable tissues;
the breathable tissue includes one or more holes that penetrate through an upper surface of the hollow cell.
5. Sandwich fabric according to claim 4, wherein the upper dial of the air-permeable zone needle tracks of the hollow cells are looped and the lower cylinder needles form one or more continuous float cells and/or one or more continuous loop cells.
6. The sandwich fabric according to claim 1, wherein the upper and lower surfaces of the supporting unit are respectively provided with planar areas arranged at intervals, a breathable area is arranged between two adjacent planar areas, and the breathable areas of the upper and lower surfaces are arranged oppositely;
the air permeable area comprises air permeable tissues arranged at intervals, and a plane tissue is arranged between two adjacent air permeable tissues;
the breathable tissue comprises one or more holes, and the holes penetrate through the upper surface and the lower surface of the supporting unit to form a channel for air convection.
7. The sandwich fabric according to claim 1, wherein the upper surface of the supporting unit is provided with planar areas arranged at intervals, and a breathable area is arranged between two adjacent planar areas;
the air permeable area comprises air permeable tissues arranged at intervals, and a plane tissue is arranged between two adjacent air permeable tissues;
the breathable tissue includes one or more holes that penetrate through an upper surface of the support unit.
8. The sandwich shell fabric according to any one of claims 2 to 7, wherein the D-value of the needle yarns of the air-permeable zone is smaller than the D-value of the needle yarns of the remaining zones.
9. The sandwich shell fabric according to any one of claims 2 to 7, wherein the needle tracks of the air-permeable zones are made of yarns smaller than 50D, and the needle tracks of the remaining zones are made of yarns larger than 75D.
10. The sandwich shell fabric according to any one of claims 1 to 7, wherein the sandwich shell fabric is used for making a garment.
