The production principle of jacquard knitted fabric
Jacquard knit jacquard jacquard's Jacquard principle. There are two points in the production of jacquard fabric and jacquard fabric. One is the complex combination of big jacquard without brown frame, and a complex combination of faucet + wire + eye plate + brown silk; two is the long jacquard plate curtain, and a N weft in a jacquard back position must be fitted with a N block plate, and a special bracket is used to hang a plate curtain and wear a line. The board is exquisite, which plate is wrong or right and right side, or both sides of the position, can weave the wrong flower shape, find the wrong pattern plate is also very troublesome, the scaffold with the board curtain is usually arranged with the jacquard faucet above the loom. There are generally 24 stripes on the small striped board, which are used to control the palm frame lifting and the selection of the weft, and a large jacquard plate has several thousand striated holes. They correspond to the number of stitches in the jacquard's faucet. Each hole is aligned with a stitch to control whether the palm is raised or not, and a grain hole controls the movement of several warps. These warps are each flower in the width of the cloth. One or a few of them, the principle is that the warp with the same track can be hung on a dragon hook through its own wire. If the number of roots is too many, more than the bearing capacity of the Dragon hook can be taken into account, in many cases, the number of threads in a hook is the number of flowers in the whole cloth. The process of information transmission are plate - lines - - - long needle hook wire harness - warp.
The advanced computerized jacquard loom jacquard machine can save the trouble of making patterns and arranging a lot of patterns. At the same time, the time from design to driving is greatly shortened, it is easy to modify, and the efficiency has been greatly improved, but the input of the equipment is much higher, which is often ten times or more of the ordinary machine.
The jacquard fabric, like the general fabric, can only do a limited amount of gauze and density, and not all the styles can be raised, because it is the big jacquard, the warp has many different weaving structures, and it may have different loom tightness so that the warp tension is uneven during the weaving process. If the tension is not mild, it can be produced and there are some unequal phenomena in the cloth face. Or easy to have a star jump. If not serious, or weaving, the weaving efficiency is very low, with a lot of defects. This requires the design of jacquard technology to take full consideration of the production feasibility, mainly depending on what tissue in the flower and ground parts, the size of the part of the jacquard, and the distribution of the flowers on the cloth surface. The factory technicians will estimate the difficulty of the production of a variety according to these factors, for the business department to offer the quotation and to refer to the order, meet the variety of production difficulty too much, the factory will give up more. The more common jacquard methods are to do the positive and negative organizations, or close organizations, such as the tribute flowers, the 1/3 flower of 3/1, the 2/2 flower of 3/1, the 1/2 flower of 2/1, or the change of the flower and ground tissues. The organization structure of the flower Department and the ground is not a moment, such as the jacquard cloth, which is the best line pattern. At the same time, it is evenly distributed on the cloth surface, trying to make the interlaced points of each warp same or similar. If we cannot do this, consider double warps or three warps, arrange the warp with similar tension on the same warp shaft, and pull the warp with different lengths separately.
