Embodiment 1
[0021] A method for preparing an elastic knitted fabric, comprising the following steps: rough weaving→width cutting→presetting→dyeing→dehydration→finished product shaping→packaging. In the rough weaving step, high F-number yarns and elastic shrinkage yarns are selected as raw materials, wherein, 50D / 72F polyester yarn and 75D / 48F polyester yarn are used for high F-number yarn, the elastic shrinkage yarn is 100D / 48F PTT / PET blended filament, and when threading on the loom, the elastic shrinkage yarn has a high line length ratio The thread length of F number yarn is increased by 10%, and then weaves double-sided fabric, the inner layer is woven with 50D / 72F polyester yarn, and the outer layer is woven with 75D / 48F polyester yarn and 100D / 48F PTT / PET blended filament Weaving; the cutting width adopts conventional technology; in the pre-setting step, the setting temperature is 150°C, and the frame width of the pre-setting machine is set to 90% of the width of the blank of the fabr...
