[0123] Performance testing

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

[0125] Table 1

[0126] 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] As can be seen from Table 1, the knitted quick-drying fabrics in Examples 1-3 have good moisture absorption, moisture permeability, breathability, UV resistance, and short drying time, especially the lightweight and dry textured knitted fabric in Example 3. This may be because the knitted sun-protective fabric was prepared using more suitable parameters in Example 3. The lightweight and dry textured knitted fabrics in Examples 1-3 also have certain UV resistance, which may be due to the addition of zinc oxide to the profiled polyester fiber, thus giving the lightweight and dry textured knitted fabric certain UV resistance.

The variation in fabric structure allows for different tactile sensations in different directions, enhancing wearing comfort. The combination of loop and float structures provides better softness and elasticity; the alternating structure allows air to circulate within the fabric, increasing breathability and helping to maintain body temperature, especially providing better ventilation during exercise; the use of float structures in the lightweight, quick-drying textured knitted fabric improves abrasion resistance, reduces the likelihood of pilling, and extends its lifespan, making it suitable for high-intensity activities such as outdoor sports; the unique structure of this invention creates an interesting textured effect, enhancing the fabric's aesthetics and meeting consumers' demands for fashion and personalization.
