Cotton-like knitted fabric, polyester long fiber and method for producing the same

摘要

The present invention relates to a cotton-like knitted fabric, a polyester long fiber, and a method for producing the same. This fabric is a weft knitted fabric knitted with a raw material containing at least 45% by weight of polyester long fibers. The pore area distribution of this fabric is centered at 6000 to 22000 μm 2, the dispersion is dispersed in a range of 2σ or more, and the variation coefficient of the pore area is larger than 40%. The polyester continuous fibers are alternately formed by twisted portions in the false twist direction and twisted portions in the reverse direction, the average length of the twisted portions in the false twist direction is 0.3 cm or less, and the length variation coefficient is 60% or more. Yes, the diameter is 30% to 70% of the reverse twist diameter, and the total length is 20.0% to 40.0% of the total length of the polyester filament. The knitted fabric of the present invention has a cotton-like appearance and has good breathability, bursting strength, water-absorbing quick-drying property and ultraviolet ray-preventing property.
