[0001] The utility model belongs to the technical field of woven fabrics, in particular to a stitched shoe midsole fabric. Background Art

[0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. The common characteristics of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to adapt to the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it must be matched with the midsole, have a braking effect when changing feet while walking to avoid slipping and easy to stop, etc.

[0003] Traditional shoes mostly use cardboard as the midsole, but its strength is poor, it is easy to break when exposed to moisture and is not durable; if ordinary non-woven fabrics are used as the midsole, although it makes up for the defects of cardboard as the midsole and the physical structure is relatively stable, it still cannot meet the physical requirements of mid-to-high-end products.

[0004] Therefore, it is necessary to provide a material as the midsole fabric that has a stable structure, good folding toughness, good air permeability and moisture resistance, longer service life, higher breaking strength, and is not easy to deform. Utility Model Content

[0007] Furthermore, the bottom layer fabric is a closed warp pile structure woven from polyester low-elastic yarn; the middle layer fabric is formed by melting and bonding polyester staple fibers and low-melting-point fibers; and the surface layer fabric is a chain-knit structure woven from polyester low-elastic yarn.

[0008] Furthermore, the bottom layer fabric and the surface layer fabric are connected by melting and bonding the low melting point fibers in the middle layer fabric.

[0009] Furthermore, the polyester low-elastic yarn is DTY 150D / 48F polyester low-elastic yarn; the polyester staple fiber is PET2.5D*64mm fiber, and the low-melting point fiber is PET4D*51mm low-melting point fiber.

[0011] Furthermore, the bottom layer fabric accounts for 15% of the total mass of the fabric, the middle layer fabric accounts for 77% of the total mass of the fabric, and the surface layer fabric accounts for 8% of the total mass of the fabric; the low melting point fiber in the middle layer fabric accounts for 35% of the total mass of the fabric, and the polyester staple fiber accounts for 42% of the total mass of the fabric. Beneficial Effects

[0012] The utility model improves the structure of the fabric, sets the bottom layer fabric to a closed warp pile structure, and sets the surface layer fabric to a closed chain weave structure, so that the front side of the fabric presents a straight grain texture, and the back side presents a twill grain texture;

[0013] The utility model uses polyester staple fibers as support in the middle layer, and melts and bonds low-melting-point fibers to make the fabric fold-resistant and tough, with a more stable structure, thereby improving its air permeability and moisture resistance and extending the service life of the midsole fabric.

[0020] The following embodiments are combined with the accompanying drawings to further illustrate a stitched shoe midsole fabric of the present invention.

[0021] like Figure 1-3 As shown, this embodiment provides a stitched shoe midsole fabric, including a bottom layer fabric 1, a middle layer fabric 2 and a surface layer fabric 3.

[0022] The bottom layer fabric 1, the middle layer fabric 2 and the surface layer fabric 3 are stacked in sequence from bottom to top, and the bottom layer fabric 1 and the surface layer fabric 3 are fixed by melting and adhering the fibers in the middle layer fabric 2;

[0023] The bottom fabric 1 is a closed warp pile structure woven from low-elastic polyester yarn; the transverse tensile force of the fabric is increased, and its transverse elongation at break is reduced;

[0024] The middle layer fabric 2 is made of polyester staple fibers and low melting point fibers melted and bonded together, making the fabric structure more stable and less prone to deformation;

[0025] The surface fabric 3 is a chain-woven structure woven from low-elastic polyester yarn, which improves the longitudinal tensile strength of the fabric and reduces its longitudinal elongation at break;

[0026] The closed loops of the warp pile structure of the bottom layer fabric 1 pass through the closed loops of the chain-knit structure of the middle layer fabric 2 and the surface layer fabric 1 and fit each other; the extension lines of the warp pile structure of the bottom layer fabric 1 are neatly arranged in a "Z" shape.

[0027] Furthermore, the bottom layer fabric 1 and the surface layer fabric 3 are connected by melting and bonding the low melting point fibers in the middle layer fabric 2 .

[0028] Furthermore, the polyester low-elastic yarn is DTY 150D / 48F polyester low-elastic yarn; the polyester staple fiber is PET2.5D*64mm fiber, and the low-melting point fiber is PET4D*51mm low-melting point fiber.

[0029] The bottom layer fabric 1 accounts for 15% of the total fabric mass, the middle layer fabric 2 accounts for 77% of the total fabric mass, and the surface layer fabric 3 accounts for 8% of the total fabric mass; the low melting point fibers in the middle layer fabric 2 account for 35% of the total fabric mass, and the polyester staple fibers account for 42% of the total fabric mass.

[0030] The fabrics mentioned above must first undergo the process of raw material storage and raw material inspection during production;

[0031] Secondly, the low melting point fiber and polyester staple fiber that meet the requirements are mixed and opened and combed in a mass ratio of 5:6, and the net is laid by a net laying machine as the middle layer fabric 2 for standby;

[0032] After warping, polyester low-elastic yarn that meets the requirements is woven into a closed chain weave on one side of the middle layer fabric 2 as the surface layer fabric 3, and a closed warp pile weave is woven on the other side of the middle layer fabric 2 as the bottom layer fabric 1;

[0033] The woven fabrics are inspected for bad fabrics and put into storage;

[0034] Then the finished product is heated and shaped, so that the low melting point fibers in the middle layer fabric 2 are melted and the fabric is bonded as a whole;

[0035] Finally, the stitched shoe midsole fabric is obtained after finished product inspection and finished product storage.

[0036] The utility model uses polyester staple fibers for support in the middle layer and melts and bonds low-melting-point fibers to ensure that the fabric has good folding resistance and toughness, a more stable structure, improved air permeability and moisture resistance, and extended service life of the sole; by using different upper and lower weaving structures and utilizing the different properties of the warp pile structure and the chain structure, the sewn shoe midsole fabric has higher longitudinal and transverse breaking strengths and smaller breaking elongations than ordinary midsole fabrics, making the structure stable and not easily deformed.

[0037] The above are only preferred implementations of the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
