Jacquard process method of jacquard machine

The jacquard process originated from the primitive waist machine to pick flowers, and this process method was already used in diagonal looms and horizontal looms during the Han Dynasty. Usually use a crouch (foot pedal) to control a meridian (a device for lifting warp) to weave patterns, in order to weave patterns, it is necessary to increase the number of heald frames, two heald frames can only weave plain texture tissue, 3-4 heald frames can weave twill tissue, more than 5 heald frames can weave satin tissue. Therefore, in order to weave complex, flower-shaped flowers with large circulation, it is necessary to divide the warp yarn into more groups, and a multi-intricate flower machine is gradually formed. According to the "Miscellaneous Notes of Xijing": There was a giant deer man Chen Baoguang's wife weaving loose flowers and silk "machine with one hundred and twenty crouches", so many comprehensive weaving is very cumbersome to weave, when it came to the Three Kingdoms, Ma Jun "the old Aya machine lost merit and cost day is to think about the change of the Aya machine" changed sixty to twelve comprehensive tips, using the method of bunching jacquards, that is, it is convenient to operate and improves efficiency.
