Sectional Warping or Pattern Warping:
Sectional warping is a two stage process which is normally used to produces fancy fabrics by using weave and color effect. In textile weaving, this system is known as indirect system or indirect warping. The other names of this warping are band warping, pattern warping and drum warping.

Beam Warping or High Speed Warping:
Beam warping or direct warping is carried out in two different steps. The main parts of beam warping or direct warping are beam, creel, pressure roller and expending comb.
Comparison Between High Speed Warping and Sectional Warping:
High Speed Warping
Uniform tension here.
Uniform tension is not available here.
Single yarn is used.
Twist yarn is used here.
Here, warp beam is produced after completing sizing process.
Here, warp beam is produced after completing warping process.
It provides higher amount of production.
It provides lower amount of production than high speed warping.
It is used to produce grey and colored fabric named common fabric.
It is used to produce fancy fabric.
Larger amount of warp yarn is required here.
Small amount of warp yarn is required here.
Here, cheese and cone winding packages are used.
Flanged bobbin is used here.
It is a cheap process.
It is ultimately a costly process.
Here, creel capacity is greater than 12000.
Here, creel capacity ranges 300 to 400.
The using of this process is very much.
It is not used as high speed warping process.
Here, production speed is high.
Lower production speed than high speed warping process.
It is used to produce warp beam from large amount of warp yarn.
It is used to produce warp beam from small amount of warp yarn.
One stage is involved here.
Two stages are involved here.
Cotton, linen, woolen and worsted yarns are processed by using this process.
It is mostly used for man-made and silk fibres.
It is a popular process.
It is not popular as high speed warping.
