The invention relates to a process for manufacturing elastic woven upper. The process comprises the following steps: A, selecting warp yarns and weft yarns; B, designing the upper, and inputting upper parameters into a shuttle loom; C, starting the shuttle loom, and weaving an initial product; D, performing laser shaping on the initial product obtained in step C so as to process the upper, wherein the initial product in step C comprises an inner woven layer, an outer woven layer, and connecting yarns used for connecting the inner woven layer and the outer woven layer, a setting process is performed between step C and step D, and the initial product is subjected to setting in the setting process by adopting a scutching and setting machine. Decorative patterns are formed by mixing and interweaving covered spandex yarns and twisted threads/high-elasticity yarns on the outer layer of the upper, the stress is balanced due to equal distribution of the yarn texture, and the inner layer of the upper is woven by taking the high-elasticity yarns as the lining, so that the lining is soft. Therefore, the upper has the advantages of high elasticity and is comfortable to wear. Due to the setting process, the upper is difficult to deform and collapse, and an attractive wearing appearance is guaranteed.
