Abstract
Provided is a warp knitting machine capable of irregularities conforming to a pattern in a warp knitted fabric. The warp knitting machine according to an embodiment is a double raschel machine, and includes at least one guide bar GB5 between a pair of jacquard bars at a front side (JB3, JB4), and a pair of jacquard bars at a back side (JB6, JB7).
Claims6
A method of manufacturing a warp knitted fabric, the method comprising:
- knitting a front-side base fabric and a back-side base fabric using a double raschel machine including a pair of jacquard bars at a front side, and a pair of jacquard bars at a back side;
- and
- forming a jacquard pattern in the front-side base fabric and the back-side base fabric using jacquard yarns fed from the respective jacquard bars, by operating jacquard mechanisms of the pair of jacquard bars at the front side, and the pair of jacquard bars at the back side, respectively,
- wherein a joining position where the front-side base fabric is joined to the back-side base fabric by the jacquard yarns due to the operation of the jacquard mechanisms, and a non-joining position where the front-side base fabric is not joined to the back-side base fabric are provided,
- insertion yarns are inserted between the front-side base fabric and the back-side base fabric by at least one guide bar disposed between the pair of jacquard bars at the front side, and the pair of jacquard bars at the back side, and
- the insertion yarns are pressed by the front-side base fabric and the back-side base fabric at the joining position of the front-side base fabric and the back-side base fabric.
