Classification of Warp Knitting Machines

There are many kinds of warp knitting machines, but no matter what type of knitting machines, their main structure is basically the same, but the specific mechanism composition is different according to the different working requirements of various machines, and they are equipped with auxiliary mechanisms for different purposes.

1. Number of warp knitting machine's needle beds

According to the number of needle beds, it can be divided into single-needle bed warp knitting machine and double-needle bed warp knitting machine.

2. Types of warp knitting machine's knitting needles

According to the types of knitting needles, it can be divided into crochet warp knitting machine, tongue knitting machine and compound knitting machine. The compound warp knitting machine includes two types: grooved needle and tubular needle.

3. Direction of warp knitting machine's fabric drawing-out

According to the direction of fabric drawing-out, it can be divided into Trico warp knitting machine and Raschel warp knitting machine. In the general knitting industry, this classification is mainly used to distinguish the types of warp knitting machines.

The main difference between Trico warp knitting machine and Raschel warp knitting machine in structure is: Raschel warp knitting machine holds the fabric with a comb-shaped grid-shaped shedding plate; Trico warp knitting machine has no grid-shaped shedding plate, while the big drop plays the role of grid-shaped shedding plate and holding coil. When Terry warp knitting machine is knitting, the angle between the drawing direction of fabric and the plane of knitting needles is about 110. Because the pulling force is almost perpendicular to the needle plane, when the knitting tension is too large, the knitting needle will bend, especially when using fine crochet, this phenomenon is obvious. Composite needles have good rigidity, so they can bear relatively large knitting tension. However, when the yarn is laid in, if the tension is too large, the looped yarn will be drawn back, which will make the knitting work unable to proceed smoothly. On raschel warp knitting machine, the angle between the drawing direction of fabric and the plane of knitting needles is about 160. Because the fabric is roughly parallel to the knitting needle, the bending moment of the knitting needle is much smaller than that of the Rico warp knitting machine.
