Abstract
A tubular double-needle bed warp knitting machine includes a warp let-off mechanism, and a loop-forming mechanism. The loop-forming mechanism includes guide needles in a circular pattern, two circular needle beds arranged internally and externally, knitting needles in a circular pattern along the internal and external needle beds, and knitting components that move in coordination with the knitting needles. Some of the guide needles form loops on the internal and external circular needle beds to connect sections of the two fabric pieces to create a three-dimensional tubular fabric. The formed three-dimensional tubular fabric gradually exits the knitting area.
