Special elastic warp-knitted fabric applicable to weft-direction cutting and preparation method of special elastic warp-knitted fabric

The invention discloses a special elastic warp-knitted fabric applicable to weft-direction cutting and a preparation method of the special elastic warp-knitted fabric. The preparation method is characterized by including steps: 1, according to customer demands, selecting fabric pattern styles, components and specifications, making a process and determining process data; 2, selecting a base material according to the process, and selecting an elastic material matched with the base material in weaving performance and dyeing performance; 3, subjecting the base material and the elastic material tobeaming; 4, carrying out onsite adjustment in warp knitting, and checking the process; 5, making a fabric reference finishing process, and making a warp-direction elasticity guaranteeing scheme. The special elastic warp-knitted fabric applicable to weft-direction cutting has advantages that by taking advantages of warp knitting, stretchability of the fabric in a natural weft direction is reduced and controlled to 10% or b
