Jacquard flower is the main method of flowering in modern warp knitting machines. In the past ten years, the Jacquard warp knitting machine has developed rapidly, from the mechanical Jaka device to the electromagnetically controlled Jacqu device, and then from the electromagnetic type to the current piezoelectric type, namely the Piezo Jaka system. The successful development of Jica in Chiai has increased the speed of the machine by 50% to 1300 rpm, and the Jacquard flower principle has been further developed. According to the different principles of Jacquard flower, it can be divided into four types: loop type, weft type, press type and floating type.
The weft-inserted Jacquard warp knitting machine has the earlier RJ4/1 warp knitting machine. Since the warp knitting machine forms a flat pattern effect, this type of Jacquard warp knitting machine is generally not used alone. The inlaid Jacquard principle is currently also applied to MRPJ25/1, MRPJ 43/1, MRPJ73/1, MRPJF59/1/24 multi-comb warp knitting machine and RDPJ6/2 double needle bed Jaka warp knitting machine. In addition, the Jacquard comb in the back of the embossed Jacquard warp knitting machine is also based on the principle of weft insertion. These models are used to form the fancy base fabric.
The old models of the gauze type Jaccarat warp knitting machine are RJG5F-NE, RJG5/2F-NE and RJSC4F-NE with electromagnetic Jaka. The new model is RJPC4F-NE. Due to the control of JIA, the speed is increased to 700 rpm, and the effect of the pattern is more colorful. Domestic introduction began this year. The patterns produced by this type of machine have a steric effect and are mainly used for the production of curtains and tablecloths.
The floating-type Jaccarat Shear warp knitting machine mainly includes RJWB3/2F, RJWB 4/2 F, RJWB8/2F (6/2 F), RJWBS 4/2 F (5/1 F). Its successful development has further developed the Jacquard principle. Now it can not only control the lateral shift of the Jacquard needle, but also control the entry and exit of the Jacquard yarn in the longitudinal direction, thus forming an independent floating effect. .
