What are the specifications of jacquard loom?
Jacquard loom According to the structure of the fabric, jacquard tissue is divided into simple jacquard tissue and complex jacquard tissue.
In short, with warp and weft, the organization that uses the original position and small pattern organization to form the pattern is called simple jacquard organization. In two or more warp, weft, multi-layer structure to form a pattern of the organization is called a complex jacquard organization.
what are the specifications of jacquard loom?
The size of the jacquard loom is distinguished by the amount of vertical needles. represented by a number (usually the number of mouths). The larger the number, the more the number of stitches. Generally, the longitudinal number of jacquard longitudinal needles is 4, 8, 12 and 16, and the transverse number of longitudinal needles depends on the jacquard number. When designing patterned fabrics (I. e. jacquard fabrics), the number of stitches used should usually be equal to the number of warp yarns in one pattern cycle (simple packaging). In addition, the number of stitches must be equal to an integer multiple of the total number of warp yarns. Otherwise, the continuity of the tissue at the intersection of the pattern may be destroyed. The number of stitches is preferably an integer multiple of the number of holes per row on the plate. This facilitates processing, rolling, manufacturing, etc.
The jacquard loom uses the diamond plate holes hung on the fire cylinder to adjust the movement of the horizontal and vertical needles, and then lifts the warp yarn through the silk connected to it. There are thousands of horizontal needles, vertical needles and thread threads in the jacquard machine, so we should deal with them one by one in order to accurately adjust the warp movement and weave the designed pattern.
jacquard loomThe positional relationship of each component is related to the installation position. On the right-hand loom, the jacquard device is installed in the upper left corner. On the left hand loom, the magnetizing machine is installed in the upper right corner. Take the right hand loom as an example to explain the sorting order and numbering of the main parts of the jacquard. The warp numbers of the jacquard fabric volunteer paintings are arranged from right to left, and the weft numbers are arranged from bottom to top. On the jacquard machine, the first end of the board is in front of the machine, and the front is close to the horizontal needle. The numbering sequence of the pattern holes is arranged from top to bottom, and the top column is the first column. The first row from front to rear is most dependent on the first action in front of the machine. The last hole in the first row in front of the machine is the first hole, and the last hole in the last row behind the machine is the last hole. The crosshead pins are arranged in a one-to-one correspondence with the plank holes, with the top pin in the front row of the cabin being the first pin (corresponding to the first hole in the plank) and the bottom pin in the last row being the last pin (corresponding to the ending hole in the plank). The order in which the vertical needles are arranged corresponds to the horizontal needles, with the leftmost needle in the first row being the first needle (corresponding to the first horizontal needle) and the rightmost needle in the last row being the endmost needle (corresponding to the last horizontal needle).
jacquard loomThe numbering order of the holes of the board corresponds to the longitudinal needle. The board is divided into multiple areas according to the number of flowers of the fabric. The direction of the holes of the board is transverse (parallel and weft), from front to back. Longitudinal (parallel and warp direction) from left to right. The first hole on the circuit board is the first hole in the leftmost row of each partial circuit board (corresponding to the first mullion), and the last hole on the circuit board is the last hole in the rightmost row of each partial circuit board (corresponding to the last mullion). The numbering sequence of this plate hole is widely used. The slope order on the plane is from left to right, opposite to the slope order on the volunteer map. The pattern direction of the meat fabric is opposite to the medical guidance.
