Types of Warping in Weaving:
There are two types of warping process used in woven fabric production. These are in the below:
- Pattern warping or sectional warping,
- Beam warping or high speed warping.

All the above two types have explained in the following:
1. Pattern warping or Sectional Warping:
In case of sectional warping, at first, equal length of warp yarn is wound in small section or sheets on a drum. After that, it is transferred to the warp beam from the drum in the format of a warp sheet.
Some important features of pattern warping or sectional warping are-
- It is costly process due to its lower production.
- It is used to produce warp beam from so many small amount of warp yarn.
- Here, tension of warp yarn cannot be kept uniform.
- It is used to produce warp beam by using twisted yarn.
- In case of sectional warping, hand weaving process is used.
- It is used to produce stripe or check fabric.
- It is also used to produce warp beam by using warp yarns which do not required any sizing materials to be applied before fabric weaving.
- After completing sectional warping, warp beam can be formed immediately here.
- In this warping process, a drum is used.
2. Beam warping or High Speed Warping:
Beam warping or direct warping is mostly used when several warp beams of same warp length have to be prepared.
Features or Characteristics of Beam Warping or High Speed Warping:
The main features of beam warping or high speed warping have listed in the below:
- It is also used to produce warp beam from larger amount of warp yarn.
- Here, the warp beam is produced after completing sizing process.
- It is used to produce warp beam from single yarn.
- It is used to produce common fabrics in large number of quantities.
- This process is sued for high speed production.
- In high speed warping, a simple flanged bobbin is used as beam.
