Note tree
The warp beam or partial warp beam is a roller that is required in the weaving preparation.
Yarn, the later warp yarn , is wound onto the card beam from a creel. The yarn from several warp beams is then brought together or assembled into a warp beam . This process is often combined with sizing , in which the yarn is coated in order to cause less friction in the weaving process.
The number of yarns on the warp beam is not as high as the warp thread density on the warp beam and in the fabric itself. Several thousand warp threads are often required next to each other for a fabric. These threads are pulled off a gate that only has space for a few hundred spools. Therefore, the threads are only wound in small numbers onto note trees before several note trees are brought together.
Note trees are always used when long warp thread lengths and only simple patterns are required. An alternative method is warping , which is more complex but allows larger patterns.
Calculation example
A 1.2 m wide fabric should have a thread count of 15 threads per cm. The fabric consists of 1800 warp threads. The creel only holds 400 bobbins. So you have to create 5 slip beams with 360 threads each, which are rewound onto a warp beam.
