[0124] The water absorption of the light and dry texture knitted fabrics in Examples 1-3 was tested by the vertical water absorption method; the moisture permeability of the light and dry texture knitted fabrics in Examples 1-3 was tested by a moisture permeability tester; the moisture permeability of the light and dry texture knitted fabrics in Examples 1-3 was tested by a moisture permeability tester; the wet samples of the light and dry texture knitted fabrics in Examples 1-3 were weighed and recorded, the samples were dried at 25°C, and the drying time was recorded; the air permeability of the light and dry texture knitted fabrics in Examples 1-3 was tested by an air permeability tester; the light and dry texture knitted fabrics in Examples 1-3 were tested for UV resistance; the test results are shown in Table 1.

[0125] Table 1

[0126] Example 1 Example 2 Example 3 Moisture absorption rate (%) 60 69 76 <![CDATA[Water vapor transmission rate (g / m 2 ×24h -1 )]]> 950 1020 1236 Drying time (min) 26 28 24 <![CDATA[Air permeability (L / m 2 ×s -1 )]]> 3945 4785 5116 UPF 65 70 85

[0127] It can be seen from Table 1 that the knitted quick-drying fabrics in Examples 1-3 have good moisture absorption rate, moisture permeability, air permeability, UV resistance and shorter drying time, especially the light and dry texture knitted fabric in Example 3, which may be due to the use of more suitable parameters in Example 3 to prepare the knitted sunscreen fabric; the light and dry texture knitted fabrics in Examples 1-3 also have certain UV resistance, which may be due to the addition of zinc oxide to the used special-shaped polyester fiber, thereby giving the light and dry texture knitted fabric a certain UV resistance.

The combination of loop tissue and floating thread tissue can provide better softness and elasticity; the alternating tissue structure design allows air to circulate in the fabric, increasing breathability and helping to maintain body temperature, especially providing better ventilation effect during exercise; the use of floating thread tissue in the light and dry texture knitted fabric improves the wear resistance of the fabric, reduces the possibility of pilling, and extends the service life, making it suitable for high-intensity activities such as outdoor sports; the unique tissue structure in the present invention visually forms an interesting texture effect, improves the aesthetics of the fabric, and meets consumers' needs for fashion and personalization.
