Abstract
The invention relates to an adjacent-connection-type hollow knitted fabric. According to the invention, a hollow structure can easily be formed, and knitting yarn modulus utilization rate can be improved. According to the invention, all knitting yarns are distributed in the knitted fabric with a checkers-type arrangement manner around a mold; each knitting yarn in the knitted fabric forms and only forms exchanges with surrounding adjacent knitting yarns around a long-straight-shape position central line of itself. Therefore, all knitting yarns are connected into an integral hollow knitted fabric with the adjacent-connection manner. Each knitting yarn only extends in a limited range in which the position central line of itself is adopted as a center and the adjacent knitting yarns are adopted as a boundary, and the position central line is the long-straight-shape on the length direction of the knitted fabric. Therefore, the hollow shape is formed, and a bending degree and a bending distribution range of each knitting yarn are reduced. Therefore, the purpose for increasing knitting yarn tensile modulus utilization rate is achieved.
