The invention provides a three-dimensional knitting technology. The three-dimensional knitting technology is characterized by being prepared by the following steps of: preparing axial yarn and knitting yarn, dividing the knitting yarn into two groups, wherein one group is composed of a first knitting yarn and a second knitting yarn, the other group is composed of a third knitting yarn and a fourth knitting yarn, and knitting the shaft yarn and each group of knitting yarn according to a two-step method. Compared with the prior art, the three-dimensional knitting technology provided by the invention has the advantages that the fabric thickness is increased by increasing the quantity of the knitting yarn relative to the traditional two-step method, so that the fabric intensity is effectively improved.
