Weaving Technology Lab experiment 1,2 and 3
EX-01
Experiment No. 01
Experiment Name: Study on different types of winding package and winding process.
Theory:
This is a process of transfer yarns from ring, bobbin, hanks etc. into a convenient form of package containing considerably long length of yarn. This simple transfer of yarn from one package (bobbin) to another large package (cone, spool, pirn) is called winding. A process of accumulating yarn on a package to facilitate the next process is known as winding.
Objects:
v To improve the quality of yarn.
v To get a suitable package.
v To get a quality fabric.
v To empty the spinners bobbin so that it can be used again.
v To clean the yarn.
v To reduce labor cost.
v To store the yarn.
v To improve the efficiency of yarn for next process.
Different types of winding packages:
a) Pirn Winding Machine
b) Cop Winding Machine
c) Spool Winding Machine
d) Cone Winding Machine
e) Cheese (Cotton) Winding Machine (Spool-Jute)
f) Warp Beam Winding Machine
g) Flange Bobbin Winding Machine
EX- 02
Experiment No. 02
Experiment Name: Study on different types of warping system.
Theory:
The parallel winding of yarn from cone or cheese packages on to a warp beam is called warping. It is the process of preparing a double flanged beam of warp yarns arranged parallel to each other.
Objects:
1. To wound up fixed (required) length of yarn on to a warp beam.
2. To increase the weavability of yarn.
3. To make dynamic next process.
4. To increase production.
5. To increase quality of fabric.
6. To make re-useable small packages.
7. To make convenient yarn sheet for sizing process.
Different types of warping system:
Mainly three types of warping are commercially used in textile industry:-
1. Beam/Direct warping (Grey/Monocolour fabric)
2. Sectional/Indirect warping (Warp patterns: Stripes and Checks)
3. Ball warping(Denim fabric)
Beam warping
1. It is suitable for grey or monocolored fabric preparation.
2. The maximum number of warp yarns in a beam can be 600.
Sectional warping
1. It is suitable for all warp patterned fabrics e.g. stripes and checks.
2. Warping is carried out section by section.
3. A single beam is prepared which may or may not be sized.
4. Sometimes this process is carried out for 2-ply synthetic warps where no sizing is needed.
5. It is a two stage process. Warping onto the drum and Beaming.
6. Creel capacity can be lower.
Ball warping
1. It is a process in which warping is done in rope form.
2. A ball warp beam is prepared for subsequent process.
3. It is suitable for denim fabric manufacturing, involving rope dyeing process.
4. It is also a 2 stage process; Ball warps winding and long chain beaming.
5. Dyeing is done before beaming operation.
EX-03
Experiment No. 03
Experiment Name: Study on slasher sizing machine.
Theory:
The process of applying a protective adhesive coating upon the yarn’s surface is called sizing. This is the most important operation to attain maximum weaving efficiency especially for blended & filament yarns. It is called heart of weaving.
The slasher sizing machine consists of the following seven units:
· Back beam unit
· Sizing unit
· Drying unit
· Cooling unit
· Dividing unit
· Measuring & marking unit
· Beaming unit
Objects:
1. To improve the weaveability of warp yarn by making it more resistant to action of weaving i.e. absorption, friction, tension & flexing.
2. To maintain good fabric quality by reducing hairiness, weakness & by increasing smoothness, absorbency of yarn.
3. To increase the tensile or breaking strength for cellulosic yarn.
4. To increase the elasticity.
5. To increase the weight of yarn.
6. To increase the frictional resistance.
7. To reduce the projection of fibres.
8. To reduce electrostatic formation for synthetic or blended yarn.

Weaving technology have lot of lab experiment , most commonly experiment r listed and explain there. For study of textile engineering this 9 experiment are needed all time. At textile university this 9 experiment are done at lab and explain that by lab report.
For a good lab report create more information are need to add there . Add more drawing by hand for make a good lab report.
In this site more textile related post are available. If you need any help please contact me otherwise make a comment in comment box.
