Jacquard
Jacquard is a large-scale pattern woven by a jacquard machine. The number of warp threads in the complete jacquard structure can reach thousands. Jacquard is mostly based on one kind of tissue, and uses another kind of tissue to show the pattern, such as plain weave and satin weave. Sometimes warp and weft yarns of different colors can be used to make the fabric show large colorful patterns. Different fiber types, yarn counts and different warp and weft densities can also be used to make various styles of jacquard fabrics. Jacquard weave is also widely used in bedding, curtains, blankets and other textiles.
The jacquard loom uses pattern needles to control the up and down motion patterns of the warp threads. Generally, the practical pattern needles of No. 1400 jacquard loom are 1480 needles, which means that there are 1480 kinds of warp thread motion patterns that can be controlled, which greatly increases the number of warp threads. The area of the flower shape.
Dobby
Dobby jacquard is a tissue that uses two or more tissue changes on the surface of the fabric to form a pattern, which is called dobby. Dobby jacquard is generally made of plain weave. Dobby jacquard fabrics are often used in high-end bedding, curtains, etc. because their patterns are finer and more delicate than large jacquard fabrics.
The small jacquard loom uses a dobby to control the lifting and lowering of the heald frame. The movement of the warp threads is determined by the lifting and lowering of the heald frame by the blades in the dobby. A general dobby can only control 16 heald frames, that is, only The movement patterns of 16 warp threads can be controlled. The patterns woven are relatively small. If you want to weave larger patterns, you can only achieve it by enlarging the cycle of drawing in and lifting out the healds. The dobby of the imported jacquard loom can control up to 24 heald frames. But this is rare, the most common ones are 16 and 20 pieces.
the difference
The main difference in the size of the jacquard pattern cycle is the difference between the looms. Small jacquard fabrics can generally be produced on a dobby loom, while large jacquard fabrics must be produced on a jacquard loom.
Jacquard fabric is a tissue with hundreds of circulating warp threads and needs to be woven with a jacquard machine. Dobby jacquard is a cotton fabric with a small pattern woven by a dobby loom, or is also called a dobby jacquard fabric.
