Winding is the process of transferring yarn or thread from one type of package to another to facilitate
subsequent processing. The rehandling of yarn is an integral part of the weaving process. Not only
must the package and the yarn itself be suitable for processing on the next machine in the production
process, but also other factors such as packing cases, pressure due to winding tension must be
considered.
Objectives:
To know about the winding process
To get knowledge of different parts of the winding machine.
To calculate the hardness of the cone
To measure the winding angle of the package
To get exact winding rate
To acquire perfect knowledge about winding and apply it in future.
Purpose of winding:
To remove objectionable faults from the yarns
To produce good package containing long continuous length of yarn.
The winding package should facilitate smooth operation of the subsequent
process
To make the suitable package for warping
To control the exact tension of the package
Types of winding:
Actually winding is divided into three types:
Parallel wound package
Near parallel wound package
Cross wound package
Winding faults:
Yarn faults
Weak yarn, Slub, Neps, Knots, Thick and thin places, Seed, leaf and other foreign matter,
Adhered loose fiber.
Package faults
Stitch or jail, Slough off, Entanglements, Wild yarns, Soft nose, Snarls.

Introduction:
The preparation of warp yarn is more demanding and complicated than that of the weft or
filling yarn. So correctly warping (Beaming) is very important for weaving and sizing
(slashing). It depends on some aspects as different condition.
What is warping?
Warping is transferring many yarns from a creel of single end package forming a parallel
sheet of yarns wound onto a beam or section beam.

Depending on the kind of intermediate carrier used, the industrial warping process can be
carried out according to two different technologies:
Sectional warping ( indirect or conical drum or dresser warping)
Beam warping or direct warping (preparatory beam warping)
Objectives:
To know about different warping systems and machines.
To get knowledge of various parts of the warping machine.
To calculate the different terminology for exact production.
To minimize the machine breakdown time.
Purpose of warping
To accelerate the next process.
To remove flies, dust, dirt particles from the yarns.
To find thin, weak place, large knots and modify.
To make the yarns uniform and control the yarn tension.
To increase the productivity and decrease the wastage of the yarns
To build a suitable package for the perfect sizing and weaving.
Direct or high speed warping:
Direct Warping Denotes the transference of yarns from single-end yarn packages, wound
packages, directly to a beam in a one step process. This means that there are an equal number
of packages in the creel area as there are ends on the beam, except in the case of a magazine
creel. A magazine creel connects the tail of one wound package to the beginning of a new
wound package for an easy package transfer, from the wound packages in the creel.
Direct warping can be used to directly produce the weavers beam in a single
operation. That is use for strong yarn such as mono filament or multifilament yarn
this is also called direct beaming.
In direct warping system there is a several method which is called intermediate
beams. This beam is used in sizing then it wind in weavers beam. If the weavers
beam contains 10000 warp ends, then there would be 9 warper’s beams of 1000 ends
each.

Operation procedure of direct warping:
The direct warping section each and every works are done accordingly. From creel to
warper’s beam the yarn are passes continues in a systematic device. Firstly input the cone in
to the cone stand in creel according to weight or length wise that can be measured previously.
Every stand contains nine package holders. The yarn are continues passes by the sensory
guide which can measure the tension of yarn and identify the yarn. In this guide there has a
suctioning system which cleans the device continuously. In Benninger warping machine the
creel capacity is 1224 and these types of creel is called v-creel. The yarn is transferred from
creel to warping machine by passes to the v-reed. The top of the machine contains v-reed
which separates each yarn eventually. Then the yarn is passing upon pre roller and winding
the warper beam. The warpers beam gets a pressure from pressure roller at the bottom of the
machine. The pressure roller supported the warper beam continuously and keeping the yarn
parallel.

Operation procedure of direct warping:
The direct warping section each and every works are done accordingly. From creel to
warper’s beam the yarn are passes continues in a systematic device. Firstly input the cone in
to the cone stand in creel according to weight or length wise that can be measured previously.
Every stand contains nine package holders. The yarn are continues passes by the sensory
guide which can measure the tension of yarn and identify the yarn. In this guide there has a
suctioning system which cleans the device continuously. In Benninger warping machine the
creel capacity is 1224 and these types of creel is called v-creel. The yarn is transferred from
creel to warping machine by passes to the v-reed. The top of the machine contains v-reed
which separates each yarn eventually. Then the yarn is passing upon pre roller and winding
the warper beam. The warpers beam gets a pressure from pressure roller at the bottom of the
machine. The pressure roller supported the warper beam continuously and keeping the yarn
parallel.

Sectional warping is one of the most important and complicated section than high speed
warping. Because it contain varies types of section or repeat which is directly input in sizing
and weaving. In sectional warping total number of ends are added together then it sized.
Every repeat is important for producing accurate width of the fabric and perfect cloth. So it
will depend on good sectional warping, which is impossible in direct warping. For these
reason it’s called sectional warping. By sectional warping we can produce cheek and stripe
fabric.
The sectional warping depends on some parameters such as:
Head stock
Control device.
Creel arrangement.
Operation procedure of sectional warping:
In the sectional warping system the yarn path is same like as direct or high speed warping.
But it has some dissimilarity from high speed warping that is pattern drum, eye reed.
Headstock, and control device. The drum and other control equipment are totally different.
Firstly should have to calculate the repeat size, width and set the other parameters perfectly.
Then arrange the creel according to the pattern chart. The yarn is transferred from cone to eye
reed into a guide that contain some weight disk, because of getting parallel, separation and
uniform tension of yarn. In there is some lease rod that is helps to separate the yarns from
different creel. For winding purposes it passes in to v-reed, and then get the section width
and wound in drum perfectly. The movements of drum and head stock are constant, that
value is input into the device with respect to the repeat width. After finished the total length is
transferred to the sized beam.

Why sectional warping is different?
In sectional warping dyed yarns are used for making the sections according to the
construction and repeat size also the total number ends that the number of colored yarns is
required for completing the sections. Actually sectional warping is to done for check or stripe
fabric production. It is very different from high speed warping. Only gray yarns are used for
high speed warping so it has fewer hazards. For that reason check or stripe fabric is costly
than solid dyed fabric.
The computerized sectional warping can automatically calculates the following:
1. Number of sections on the beam and width of each section.
2. Constant warp tension regulation for uniform buildup
3. Automatic stops for predetermined length
4. Automatic stops for leasing
5. Constant warp tension over the full warp width
6. Memory of yarn breakage during warping for beaming
Faults in warping
1. Practically for winding
2. Machine fault
3. Operator misconception
4. Low quality yarn
5. others
Problems in warping
a. Overlapping problem
b. Soft yarn
c. Incorrect form of beam
d. Loose selvedge (depends on tension)
e. Incorrect warp length
f. Big knot
Checking have to done during warping:
1. Lot mixing
2. Count mixing
3. Color variation

What is sizing:
The process of applying a protective adhesive coating on the yarns surface of yarn is called sizing.
This is the most important operation to attain maximum weaving efficiency. Especially for blended
and filament yarns. Sizing increases elasticity of yarn, Yarn strength, weight of yarn, smoothness,
frictional resistance. Sizing consists of impregnating the yarn with particular things which form on the
yarn surface a film with the aim of improving yarn smoothness and tenacity during the subsequent
weaving stage. Thanks to its improved tenacity and elasticity, the yarn can stand without problems the
tensions and the rubbing caused by weaving.
Purpose of sizing:
To improve the weave ability of the warp yarn
To maintain good fabric quality by reducing hairiness, weakness and by increasing
smoothness, strength of yarn.
To increase the tensile or breaking strength for cellulose yarn.

Sizing Technique:
All beams previously wound on the beam warper are mounted on a special beam creel. The threads
are taken off in sequence from all beams and introduced into a vat containing the proper size. The
warp enters then a drying unit, where the water contained in the threads is evaporated, this result is
obtained by direct contact of the threads with cylinders having decreasing temperature having steam
line. These last are a real innovation and operate as follows: the electromagnetic field generated by
radio-frequency permits to extract the water contained in the glue, without heating the threads. By
avoiding the thermal shock caused by hot air ovens, it is possible to maintain unchanged the chemical
and physical properties of the yarn; this is a must when yarns sensitive to heat are processed. It is
important to take care that during sizing the threads do not stick together, but remain separate in order
not to create problems during the downstream processes. The drying unit is followed by a waxing
device which is aimed at increasing the threads smoothness. The process concludes with the winding
by an end frame of the threads on a weaver’s beam at a speed up to 80 meters/min. Between the
drying unit and the end frame there are lease rods: these are available in the same number as the
beams under process minus one and have the function of keeping the threads separate and of
preventing that they get entangled and are not wound up with the correct sequence.
A recent variation to the traditional system carries out sizing during beam warping and therefore
assembles already sized beams. The advantage is the possibility of sizing beams, each with a warp
rate (threads per cm) x times (x = number of beams) lower than the effective warp rate in the weaver’s
beam.
Reason for different sizing recipe:
Sizing is a complementary operation which is carried out on warps formed by spun yarns with
insufficient tenacity or by continuous filament yarns with zero twist. In general, when sizing is
necessary, the yarn is beam warped, therefore all beams corresponding to the beams are fed, as soon
as warping is completed, to the sizing machine where they are assembled.
There is not just one sizing ″recipe″ which is valid for all processes, on the contrary the sizing
methods depend on the type of weaving machine used, the construction of fabric, on the yarn type
and count, on the technician’s experience and skill, but all kinds of material in progress. The only
common consideration of the various sizing materials is that they have to be easily removable after
weaving in order to allow carrying out without any problems for the selected finishing cycle. The
substances used as sizing material are potato flour, starches, glues, fats but also talc and kaolin, when
a particularly thick size is required.

rate (threads per cm) x times (x = number of beams) lower than the effective warp rate in the weaver’s
beam.
Reason for different sizing recipe:
Sizing is a complementary operation which is carried out on warps formed by spun yarns with
insufficient tenacity or by continuous filament yarns with zero twist. In general, when sizing is
necessary, the yarn is beam warped, therefore all beams corresponding to the beams are fed, as soon
as warping is completed, to the sizing machine where they are assembled.
There is not just one sizing ″recipe″ which is valid for all processes, on the contrary the sizing
methods depend on the type of weaving machine used, the construction of fabric, on the yarn type
and count, on the technician’s experience and skill, but all kinds of material in progress. The only
common consideration of the various sizing materials is that they have to be easily removable after
weaving in order to allow carrying out without any problems for the selected finishing cycle. The
substances used as sizing material are potato flour, starches, glues, fats but also talc and kaolin, when
a particularly thick size is required.

Sizing Technique:
All beams previously wound on the beam warper are mounted on a special beam creel. The threads
are taken off in sequence from all beams and introduced into a vat containing the proper size. The
warp enters then a drying unit, where the water contained in the threads is evaporated, this result is
obtained by direct contact of the threads with cylinders having decreasing temperature having steam
line. These last are a real innovation and operate as follows: the electromagnetic field generated by
radio-frequency permits to extract the water contained in the glue, without heating the threads. By
avoiding the thermal shock caused by hot air ovens, it is possible to maintain unchanged the chemical
and physical properties of the yarn; this is a must when yarns sensitive to heat are processed. It is
important to take care that during sizing the threads do not stick together, but remain separate in order
not to create problems during the downstream processes. The drying unit is followed by a waxing
device which is aimed at increasing the threads smoothness. The process concludes with the winding
by an end frame of the threads on a weaver’s beam at a speed up to 80 meters/min. Between the
drying unit and the end frame there are lease rods: these are available in the same number as the
beams under process minus one and have the function of keeping the threads separate and of
preventing that they get entangled and are not wound up with the correct sequence.
