each interlocked course of the plurality of interlocked courses (720A-C) comprising a plurality of interlocking cross overs (1424, 1426, 1428, 1430), each of which comprises the first yarn strand (116, 1418) and the second yarn strand (118, 1420) crossing over one another to change positions between a respective front-stitch course and a respective back-stitch course; in each interlocked course, the plurality of interlocking cross overs (1424, 1426, 1428, 1430) dividing the respective front-stitch course and the respective back-stitch course into a plurality of front-stitch subsets and a plurality of back-stitch subsets, wherein each interlocked course includes a plurality of knit tubular structures, each of which is comprised of a pair of adjacent interlocking cross overs (1424, 1426), a front-stitch subset, and a back-stitch subset, wherein the plurality of knit tubular structures are arranged side by side across the tubular-jacquard knit region; the tubular-jacquard knit region being divided into a first knit zone, a second knit zone, a third knit zone, a forth knit zone, and a fifth knit zone, which are consecutively arranged in a side-by-side configuration, wherein each interlocked course includes a first subset of knit tubular structures corresponding with the first knit zone, a second subset of knit tubular structures corresponding with the second knit zone, a third subset of knit tubular structures corresponding with the third knit zone, a fourth subset of knit tubular structures corresponding with the fourth knit zone, and a fifth subset of knit tubular structures corresponding with the fifth knit zone; the second subset of knit tubular structures and the fourth subset of knit tubular structures including two or more knit tubular structures each having at least two and fewer than seven front stitches and at least two and fewer than seven back stitches; and the first subset of knit tubular structures, the third subset of knit tubular structures, and the fifth subset of knit tubular structures each comprising a single knit tubular structure that comprises at least seven front stitches and at least seven back stitches. the plurality of front-stitch courses (112, 1414) and the plurality of back-stitch courses (114, 1416) being constructed of a first yarn strand (116, 1418) and a second yarn strand (118, 1420), wherein each front-stitch course of the plurality of front-stitch courses (112, 1414) intermittently interlocks with a back-stitch course of the plurality of back-stitch courses (114, 1416) to form a plurality of interlocked courses (720A-C); each interlocked course of the plurality of interlocked courses (720A-C) comprising a plurality of interlocking cross overs (1424, 1426, 1428, 1430), each of which comprises the first yarn strand (116, 1418) and the second yarn strand (118, 1420) crossing over one another to change positions between a respective front-stitch course and a respective back-stitch course; in each interlocked course, the plurality of interlocking cross overs (1424, 1426, 1428, 1430) dividing the respective front-stitch course and the respective back-stitch course into a plurality of front-stitch subsets and a plurality of back-stitch subsets, wherein each interlocked course includes a plurality of knit tubular structures, each of which is comprised of a pair of adjacent interlocking cross overs (1424, 1426), a front-stitch subset, and a back-stitch subset, wherein the plurality of knit tubular structures are arranged side by side across the tubular-jacquard knit region; the tubular-jacquard knit region being divided into a first knit zone, a second knit zone, a third knit zone, a forth knit zone, and a fifth knit zone, which are consecutively arranged in a side-by-side configuration, wherein each interlocked course includes a first subset of knit tubular structures corresponding with the first knit zone, a second subset of knit tubular structures corresponding with the second knit zone, a third subset of knit tubular structures corresponding with the third knit zone, a fourth subset of knit tubular structures corresponding with the fourth knit zone, and a fifth subset of knit tubular structures corresponding with the fifth knit zone; the second subset of knit tubular structures and the fourth subset of knit tubular structures including two or more knit tubular structures each having at least two and fewer than seven front stitches and at least two and fewer than seven back stitches; and the first subset of knit tubular structures, the third subset of knit tubular structures, and the fifth subset of knit tubular structures each comprising a single knit tubular structure that comprises at least seven front stitches and at least seven back stitches.
