[0067] 2. The fabric of the present invention has the properties of comfortable hand feeling, quick-drying, antibacterial and deodorizing properties: (1) 40S microporous blended yarn is interwoven with 50D / 36F DuPont SORONA two-component fully stretched polyester FDY filament; wherein the 40S microporous blended yarn is mixed with three kinds of fibers in a certain proportion: polyester accounts for 50%, cotton accounts for 25%, and modal accounts for 25%; this microporous blended yarn is covered on the 50D / 36F DuPont SORONA two-component fully stretched polyester FDY filament, and the close contact with the skin will bring a soft and comfortable wearing experience, which is more suitable for autumn Sportswear; (2) The fabric is woven with a jersey structure. The 40S microporous blended yarn on the front has a unique hollow structure due to the alkali reduction process during the dyeing and finishing process. The fabric can store some air and reduce air circulation, thereby having a better warming effect; (3) The fabric of the present invention is woven on a single-sided circular knitting machine with a cylinder diameter of 30 inches and a machine number of 28 needles / inch. The fabric has the characteristics of being light, thin and soft; (4) The fabric is subjected to an antibacterial process during the dyeing and finishing process, which gives the fabric the functions of antibacterial, deodorizing, moisture absorption and breathability, making it more comfortable and healthy to wear.

[0068] 3. The production method of the fabric of the present invention is simple: the fabric can be woven on a single-sided circular knitting machine with a cylinder diameter of 30 inches and a needle arrangement of 28 needles / inch, and has the characteristics of simple preparation process.

[0069] The single-layer alkali-reduced lightweight quick-drying antibacterial weft-knitted fabric produced by the method is left to stand for 48 hours under standard conditions, and then the moisture absorption and quick-drying properties of the fabric are tested with reference to the standard. The corresponding standards and test results are shown in Table 2.
