The invention discloses a finishing technology of a warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyed fabric, and relates to a finishing technology of a cotton type elastic easy-care fabric. The technology comprises the steps of singeing, desizing, mercerizing, washing, preshrinking, high-temperature setting, easy-care finish and baking. An ordinary yarn-dyed fabric production route is changed in the technology process, wherein washing is conducted after mercerizing is conducted, and then sufficient alkali removing can be guaranteed; preshrinking is conducted directly,it is guaranteed that large enough elasticity is achieved in the radial direction. Accordingly, it can be guaranteed that the warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyedshirt fabric is produced smoothly, a shirt is made by adopting the warp and weft cotton type elastic easy-care fabric, when people do body movement, limitation does not exist in the four directions, and people feel comfortable and free when wearing the shirt; due to the fact that elastic yarns exist in four directions, after deformation, the elastic yarns can return to the original position, and the aesthetic feeling of being neat in shape is guaranteed.
