Shyamoli Textile Engineering College is affiliated with the University of Dhaka. Weaving involves interlacing two sets of threads at right angles to each other to form fabric - the warp runs longitudinally and the weft crosses it. The warping process transfers yarn from packages to a section beam, which must have uniform tension, no defects, and be smooth. Weaving requires three operations - shedding to separate warp threads into layers, picking to pass the weft through the shed, and beating-up to push the weft pick into the woven fabric.

4. Weaving is a method of textile production in which two distinct sets of
yarns or threads are interlaced at right angles to form a fabric or cloth.
The warp threads run lengthways of the piece of cloth, and the weft runs
across from side to side.
In general, weaving involves using a loom to interlace two sets of threads at
right angles to each other: the warp which runs longitudinally and the weft
(older woof) that crosses it. One warp thread is called an end and one weft
thread is called a pick.

6. The warping process transfers the yarn from multiple packages to a section
beam. To produce a quality beam suitable for weaving, the following must
be accomplished:
1) no lint, fly, wild yarn
2) no high or low selvage
3) maintain warper speed
4) maintain braking systems
5) no crossed or loose ends
6) uniform tension across beam
7) uniform tension beam to beam
8) smooth section beams, rollers

9. In order to interlace warp and weft threads to produce fabric on any type
of weaving machine, three operations are necessary :
A) Shedding: Separating the warp threads, which run down the fabric
into two layers to form a tunnel known as the shed
B) Picking: Passing the weft thread, which traverses across the fabric,
through the shed
C) Beating-up: Pushing the newly inserted length of weft, known as the
pick, into the already woven fabric at a point known as the fell
