To study the fully forming process implementation method of casual dress tops,based on the analysis of the pattern design of casual dresses,a two-dimensional pattern design of clothing is carried out,and the paper pattern size is transformed into knitting technology.By analyzing the principle of fully formed weaving,the key processes are studied and discussed.Finally,a fully formed round neck ruffle edge dress style top is completed using polyester yarn as the raw material.The results show that the degree of wrinkling on lotus leaf edges is related to the number of changing needles,weaving rows,and edge needles,but not to the number of stitches;The formation of flat shoulder sleeves requires the use of proportional weaving to achieve the weaving of hanging shoulder structures and flat-sleeve mountain structures.
