Among them, the first warp yarn 11 includes at least one of a first polyester fiber 111 and a first polyester fiber 112, the first weft yarn 12 includes at least one of a first pure cotton fiber and a second polyester fiber, the ice silk yarn 21 includes a fourth pure cotton fiber 211 and a third polyester fiber 212 and / or a first modal fiber 213 spirally wound on the fourth pure cotton fiber 211, the second warp yarn includes at least one of a first viscose fiber and a second pure cotton fiber, and the second weft yarn includes at least one of a third pure cotton fiber and a second polyester fiber.

[0024] In this embodiment, the first warp yarn 11 is formed by twisting the first polyester fiber 111 and the first polyester fiber 112, and the first weft yarn 12 is formed by twisting the first pure cotton fiber and the second polyester fiber. The accompanying drawings only show the schematic diagram of the winding structure of the first warp yarn 11, and the winding forms of the first weft yarn 12, the second warp yarn, and the second weft yarn are the same as the first warp yarn 11.

[0025] In this embodiment, the ice silk yarn 21 is composed of a fourth pure cotton fiber 211 and a third polyester fiber 212 and a first modal fiber 213 spirally wound around the outside of the fourth pure cotton fiber 211, and the ratio of the third polyester fiber 212 to the first modal fiber 213 is 1:2.

[0026] In this embodiment, the second warp yarn is formed by twisting the first viscose fiber and the second pure cotton fiber, and the second weft yarn is formed by twisting the third pure cotton fiber and the second polyester fiber.

[0027] In this embodiment, the surface fabric 1, the middle fabric 2 and the inner fabric 3 are all woven fabrics. With the same yarn material, the woven finished product is lighter and more sun-proof. The three layers of fabric in this embodiment are all woven according to the plain weave. The attached figure only shows the organizational structure diagram of the surface fabric 1, and the organizational structures of the middle fabric 2 and the inner fabric 3 are the same as the surface fabric 1. In another preferred embodiment of the utility model, the surface fabric 1, the middle fabric 2 and the inner fabric 3 are all woven according to the texture jacquard weave. With the same yarn material, the UV resistance of the fabric formed by weaving the texture jacquard weave is much higher than that of the basic plain weave.

[0028] In this embodiment, the connection methods of the surface fabric 1, the middle fabric 2 and the inner fabric 3 mainly include the following three methods: suturing connection, adhesive connection and connection through a knotted tissue. At least one of these connection methods can be selected according to actual needs.

[0029] In the bonding method, in order to ensure the air permeability of the fabric, a plurality of adhesive points 4 distributed in an array are respectively arranged on the surface of at least one of the surface fabric 1 and the middle fabric 2, and on the surface of at least one of the middle fabric 2 and the inner fabric 3, and the surface fabric 1 and the middle fabric 2, and the middle fabric 2 and the inner fabric 3 are bonded by the adhesive points 4.

[0031] The functional fabric provided in this embodiment is tested according to the test method specified in GB / T 18830-2009, and the result is that the ultraviolet protection factor (UPF) is 142, and the ultraviolet (UPF) AV 158.9, which is greater than the standard value of 100, and the ultraviolet transmittance T (UVA) AV0.81%, which is much less than the standard value of 5%, which shows that the fabric has outstanding sun protection performance.

[0032] The greater the heat shielding rate of clothing fabrics, the more light radiation the fabric blocks; the lower the maximum temperature, the lower the body temperature after the fabric is worn. Currently, the heat shielding rate of clothing fabrics on the market is mostly 30%-40%; FZIT 73067-2020 "Contact Cool Knitted Clothing" stipulates that the instantaneous coolness coefficient qmax of superior clothing is

[0033] Not less than 0.25, first-class products not less than 0.20, qualified products not less than 0.18; GB / T 5453-1997 uses air permeability (referring to the rate at which air flows vertically through a sample under specified sample area, pressure drop and time conditions) to indicate the air permeability of fabrics. In the industry, air permeability greater than 200 mm / s is generally appropriate. According to the performance test results in the table below, the sunscreen functional fabric of this embodiment has excellent thermal insulation and air permeability and touch coolness.

[0034]

[0035] The utility model provides the fabric with richer heat insulation and sun protection functions through the composite layer structure formed by the surface fabric 1, the middle fabric 2 and the inner fabric 3, wherein the middle fabric 2 is woven with ice silk yarn 21, which can not only bring better breathability but also bring a cool experience.
