3. Warping
The parallel winding of warp ends from
many winding packages (cone, cheese) on to a common
package (warp beam) is called warping.

4. Warping process involves

5.  To wound up fixed length of yarn on to a warp beam
 To increase the quality of yarn
 To make re-useable small package
 To make convenient yarn sheet for next sizing process
 To make dynamic next process
 To increase the production
Objects of warping

6.  Construction of a beam of warp yarn.
 Construction of a parallel yarn sheet.
 Modifying the faults of yarn like thick or thin place.
 Winding the pre- determined length of yarn.

Importance of Warping:

7. Types of Warping
Sectional warping.
High speed warping.
 Features of sectional warping:
 To produce fancy fabric.
 Hand weaving used in Sectional warping.
 To produce weavers beam from small amount of warp yarn.
 To produce weavers beam from twist yarn.
 Production is less, so it is costly process.
 Yarn tension can not be kept uniform.
 A tapered beam or drum is used.

8. Features of high speed warping:
 To produce common fabrics in large quantities.
 To produce weavers beam from single yarn.
 For high speed production.
 The weavers beam is produced after sizing.
 A simple flanged bobbin is used as beam.

9. Difference between High speed
warping and Sectional warping:
High speed warping Sectional warping
1. To produce common fabric. 1. To produce fancy fabric.
2. High production. 2. Lower production.
3. Large amount of yarn required. 3. Small amount of yarn required.
4. Creel capacity is greater than 12000. 4. Creel capacity is 300 to 400.
5. Cone, cheese winding is used. 5. Flanged bobbin is used.
6. Single yarn is used. 6. Twist yarn is used.
7. Cheap process. 7. Costly process.

10. • High Speed Warping or Beam warping :
High speed warping also called Beam warping/Direct warping. In high speed
warping the yarn is wound parallel on the warping beam. All the yarns are
wound at once and simple flanged beam is used. It is a very high speed
process and is used for making fabric of single color

11. The main machine elements are:
1. Creel 2.Expending comb 3. pressure roller 4. Beam

12. Working principle of High speed warping:
This warping is carried in two separate stages:
• At first the proper warping takes place : the available threads are wound
on a large cylinder beam and so many beams are prepared.
• In second stage the threads wound on the beams are together unwound
to form the weavers beam.

13. Features of High Speed Warping
• It is used to make common fabrics in large quantities
• It is used to produce weavers beam from single yarn
• The production is high
• Large amount of yarn is required to produce a weavers beam
• Sizing is done
• Simple flanged beam is used and drums are not required

14. Advantage or disadvantage
of sectional and high speed
warping
Warping is important for weaving process. Warping process
are mainly two types they are as follow. Advantage or
disadvantage of sectional and high speed warping.

15. 1. Sectional warping or pattern warping.
2. High speed warping or beam warping or direct warping.
Sectional warping process Picture

16. Comparison Between High Speed Warping and
Sectional Warping:
Uniform tension here
Uniform tension is not available here.
Single yarn is used. Twist yarn is used here.
It provides higher amount of
production.
It provides lower amount of
production than high speed
warping.
Larger amount of warp yarn is
required here.
Small amount of warp yarn is
required here.

17. Creel capacity is high. Lower creel capacity.
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.
One stage is involved here. Two stages are involved here.
It is a popular process. It is not popular as high speed
warping.

19. COMPONENTS OF CREEL
1.Cone or cheese spindle for high speed & peg for sectional warping.
2.Thread guide: To pass through the yarn in the required way.
3.Tensioner: To keep the yarn always in a uniform tension.
4.Yarn cleaner: To remove various faults of yarn like slubs, neps etc.
5 Suction fan or blower: To remove the dirt and dust from the yarn.
6.Breakage indicator: To indicate breakage in package.
7.Stop device: To stop the machine when yarn will be broken.

20. COMPONENTS OF HEAD
STOCK
1.Adjustable or variable v-reed or wraith: To control the width of the warp beam.
2.Measuring and marking device: Measure the amount of warp yarn on the beam
and marks the yarn.
3.Yarn speed controlling device: To control the speed of yarn.
4.Pneumatic pressure unit: To press the warp beam with the surface contact of
driving drum.
5.Break assembly: It stops the machine instantly in case of yarn breakage.

21. Creel
What is creel ?
A structure for mounting supply packages in textile processing. It is
situated behind the headstock in an upright position.
 Objectives of creel:
 The creel is a stand for holding the supply packages in the form of wound packages.
 It enables to hold the supply packages in proper position for warping
 No single type of creel can give the same beaming efficiency for different types of yarns or
applications

22. Figure of creel:

23. Creel structure:
Spindle
Pegs
Guides
Tensioners
Creel capacity:
The amount of package which is contained in creel is called Creel capacity.
Creel capacity depend upon the
Number of the rod of the creel
Number of the spindles that holds the cones on the creel
• In Sectional warping Creel capacity is 300-400.
• In high speed warping 1200.

24. Types of creel:
1. Single end Creel.
a) Track creel (Creel moves)
b) Duplicated creel (Headstock moves)
2. Magazine creel.
3. Traveling creel.
Single end creel: Single package is associated with each end being wound on
beam. The creel packages contain same amount of yarn to produce an integral
no of beams.

25. Figure of Single End Creel:
Magazine creel: Magazine creel is a multiple package creel. Two packages are
used for winding on beam. The tail of first package is tied with the loading end
of the second package.

26. Figure of Magazine Creel:
Traveling creel:
In traveling creel the package carriers move in loops. Here
while the yarns outside the loops being with drawn the inside yarns are
creeled at a time.

28. Total length of warp yarn produced
No of beam produced = ……………………………………………………..
Length of warp yarn on a beam
Total warp yarn length X No. of ends
Total weight of yarn per drum = ………………………………………………………….
Yarn count
Total weight of yarn per drum
Weight of yarn of a beam = …………………………………………………….
No of beam produced
Total length of warp produced = Calculated production per min X Efficiency
 Formulas for Warping:

29. Calculate the length of warp that can be produced per day of 8 hrs on a
improved high speed beam warper if the warping speed is 610 yds per
min. The efficiency is 75%.
Solution:
We know,
Actual length of warp produced per 8 hrs =Calculated production per min X
Efficiency X 60 X 8
=610 X 60 X 8 X (75/100) yds
= 219,600 yds

30. Calculate the beam count of the yarn on a set of 6 slasher
beams, each of which contains 525 ends of 12,000 ends of
12,000 yds , at wt of warp on back beams is 12,000 lbs.
Solution: Total ends = 525 × 6 = 3150
We know,
Beam count =
=
= 37.5 S

31. 8 sets of 6 warpers beams each is to be produced on 4 warping
machines. The length of warp on each beam is required to be 14,000 yds.
If the production (actual) of each machine is 2800yds per hr. How long
will it take to complete the sets ?
Solution: Total length of warp in yds =Length of warp in ydr required
per beam X No of ends X No of Beam
= 14000 X 6 X 8 yds
= 672000 yds.
Time required =
=
=61 hrs
