摘要： The present invention discloses a cotton-like knitted fabric, a polyester filament and a production method thereof. The fabric is a weft-knitted fabric obtained by material containing at least above 45% by weight of polyester filaments; the pore area distribution of the fabric is centered on 6000 to 22000 µm 2 and has a statistical variability of above 2σ, and the coefficient of variation of the pore area is greater than 40%. The polyester filament is formed from alternatingly arranged twist regions in a false-twist direction and twist regions in an opposite direction, wherein the twist regions in the false-twist direction have an average length of less than 0.3 cm, a coefficient of variation of length of above 60%, a diameter that is 30% to 70% of the diameter of the twist regions in the opposite direction, and a total length that is 20.0% to 40.0% of the total length of the polyester filaments. The knitted fabric of the present invention feels like real cotton, and is excellent in air permeability, bursting strength, hydroscopic and fast-drying performance, and ultraviolet resistance.
