Weaving
• Interlace between two sets of yarn
• Weaving is the crossing of yarns at
right angles or strips of other
materials to produce a flat, more or
less compact surface.

Weaving Preparatory Process
• Before weaving, the weaver beam
needs some few operations before
placing the beam on loom
• Warping
• Sizing
• Drawing

Warping
• To make bigger package to supply
warp yarn
• Yarn with uniform tension

Sizing
• The purpose of sizing to increase
weaving resistance
• Resistance against abrasion
5

Drawing in
• The drawing-in of the sized warp
threads through the heald eyes, reeds
and drop-wires of the loom
• May be done either manually by a pair
of workers

Types of Looms
• Hand loom
• Power Loom
• Jacquard Looom
• Air Jet Loom
• Water Jet Loom
• Rapier Loom
• Sulzer Loom
• Projectile

Loom Chart

• Handloom :
weaver could sit at the centre of the loom and
merely pull the handle to make the shuttle move
from one end of the fabric to insert a weft
thread.

• Power loom :
Earlier version of power loom were run by two man. Soon
power looms were driven by steam and most of the
wooden parts were replaced with iron. The average
speed of the power loom had increased from 60 to 140
picks per minute with the rise on productivity.
• Productivity of this m/c is very low upto 20 to 24 meter
per day
• The weft insertion is done thru shuttle which has a
capecity of 10 meter, iot means after every 10 meter
there will be a knot

• Automatic Loom/Shuttleless loom :
Traditional Power looms were stopped every few minutes
in order to replace the empty weft pirns in the shuttle and
this limited the number of looms, a weaver could operate
to about four. Later an automatic weft transfer system
which replaced the weft pirn in the shuttle without slowing
or stopping the loom. The average speed of the
Automatic loom is 100 to 200 meter per day.
•

• Shuttleless Loom :
The dynamic problems created by the picking
and checking mechanism and the inherent
process of pirn winding for shuttle looms had
encouraged the loom makers to develop
alternative means of weft insertion in which
heavy shuttle is not projected forwards and
backwards across the width of the loom. It is
customary to refer these looms as shuttleless
looms.

• MAJOR FAULTS
• Starting Mark
• Double Pick
• Brocken Pick
• Thick Place
• Miss Pick
• CUTTABLE FAULTS
• Crack
• Tear
• Fabric Cut
• Multiple Breakage
• Float
• CONTINUOUS FAULTS
• Wrong Pattern
• Missing End
• Stitches
• Reed Cut
• Temple Cut
• MENDABLES
• Loom Fly
• Bent Pick
• Hanging Thread
• Snarling
• Loops

Woven structures Plain weave

Woven structures
Twill weave
Twill weave, the secondbasic
weave, is characterized by
diagonal lines running at angles
varying between 15° and 75°. A
twill weave is denoted by using
numbers above and bellow a line
(such as 2/1 twill which may be
interpreted as two up and one
down in the shedding sequence).

Woven structure
Satin and Sateen weave
Sateen weave is the third basic
weave, in which the interlacing
points are arranged in a similar
way to twill weaves but without
showing the twill line. The satin
weave is warp face weave and
the sateen is a filling face weave.
Fig. Shows 5 ends (Harness)
satin. In this case, the repeat is on
5 ends x 5 picks.
