‘Beating’ is one of those weaving words that sounds much more dramatic than it really is. Each time a weaver throws a line (or ‘pick’) of weft, they need to push that weft into place to make a clean and even grid. This is called beating the weft. On a multi-shaft loom, you beat by swinging the beater bar towards you.
What is beating up in loom?
Introduction: The beating up is the third primary motion of weaving. It consists in driving the last pick of weft to the fell of the cloth. This is accomplished with the help of a reed fixed in the sley. The sley is given a sudden and quick movement direction to the fell of the cloth by the cranks in crank shaft.
What are the steps in weaving?
Steps of Fabric Strip Weaving
- Preparing the Warp. After designing the color way and color order of the warp the cotton yarn is measured onto a warping board.
- Preparing the Loom. The next process is to thread the loom and wind the yardage onto the loom.
- Fabric Selection. The fabric strips are like a palette.
What are the four types of weaving?

- Basket Weave. A basketweave fabric is an alternative form of the plain weave. …

- Satin Weave.
What does warp mean in weaving?
weaving, lengthwise yarns are called warp; crosswise yarns are called weft, or filling. Most woven fabrics are made with their outer edges finished in a manner that avoids raveling; these are called selvages. They run lengthwise, parallel to the warp yarns.
What is shedding in textile?
Shedding. Shedding is the process of creating an open path across and through the warp yarns by raising some warp threads by their harnesses and leaving others down. While the shed is open, the filling yarn is inserted.
What is negative tappet shedding?
Negative Tappet Shedding : It is the type of tappet shedding where shedding mechanism is done by means of negative tappet (cam). The negative shedding cam gives one direction movement that means it gives upward or downward movement.
Why beat up is done during weaving?
Introduction: The beating or beat-up is the third primary motion of weaving. It is also the last operation of the loom in weaving in which the last pick inserted in the fabric is ‘beat’ into position against the preceding picks. It consists in driving the last pick of weft to the fell of the cloth.
What is block weave?
Block weaves are structures in which groups of warp and weft threads can produce two different-looking interlacements, one that identify as “pattern,” the other as “background.” … Other writers say a block weave is a weave structure that produces a pattern area and a ground area.
Why warping is done?
Warping is the process of combining yarns from different cones together to form a sheet. The important point in the warping is to preserve the yarn elongation and maintain it at uniform level. This is done to achieve a better performance during weaving in terms of low end breakage rate.
What are the 3 basic weaves?
The basic weaves include plain (or tabby), twills, and satins.
What is dobby pattern?
Dobby, or dobbie, is a woven fabric produced on the dobby loom, characterised by small geometric patterns and extra texture in the cloth. The warp and weft threads may be the same colour or different. … Dobby usually features a simple, repeated geometric pattern. Polo shirts are usually made with dobby.
What weave pattern is cotton?
Plain-weave is the most common type of weave, where the horizontal (weft) yarns alternately pass over and under the vertical (warp) yarns to create strong, hard-wearing fashion and furnishing fabrics. As a technique and a fabric, plain-weave fabric dates to ancient times.
Which is stronger warp or weft?
Warps yarns are stronger compared to weft yarns. During the weaving warps are held under high tension, moves up and down for shed formation. Warp yarns are finer than weft yarns. The weft yarn is inserted over-an-under the warp yarns.
What are weft and warp threads?
Warp: Threads running the length of the loom across which threads are woven. Weft (filling): Threads which are woven crosswise to the warp to form the web.
What is Tabby in weaving?
Tabby weave is the simplest weave binding system. It is based on two or more warp threads (ends) and two or more weft threads (picks). … A balanced tabby weave is where there are the same number of threads per square centimetre in the warp and weft. Also called: cloth weave; plain cloth; plain cloth weave; plain weave.
