The invention discloses a tattered ripped effect imitation jean seamless knitted fabric. The fabric comprises a loop transfer stitch, inner and outer layer alternated layer figured texture stitches and other stitch structures, and the ripped and washed tattered appearance effect of a traditional jean product is simulated. The loop transfer stitch is a parallelogram formed by arranging vertical columns of one loop transfer loop and a plurality of non-woven loops in a stepped mode, the upper and lower edges of the parallelogram have the inclined angles of 45 degrees, and the loop column and rownumbers range from 10 to 150. The inner and outer layer alternated layer figured texture stitches are formed by alternating two or more sets of yarn, the tattered effect generated by surface color changes of the jean fabric and the garment can be simulated, and the washing tattered effect is formed. Due to the seamless knitted technology, the jeans fabric and the garment have the more soft and elastic texture, and the wearing comfort is improved; in addition, due to the integrated molded weaving technology, the complex old washing production technology and consumption of chemical agents can beomitted, and the fabric is environmentally friendly and efficient.
