10. DRAWING FRAME
Drawing is a operation by which slivers are blended, doubled or leveled
and by drafting reduced to proper sized sliver suitable of being fed to
simplex
It influence on quality of yarn(final product), as draw frame is the last
point of compensation for the elimination of error to produced by
subsequent m/c
OBJECTIVES:
Drafting
Parallelization
Improved Evenness
Dust Removal

13. Manufacturing of the fibre forming polymer.
Spinning ( extrusion through spinneret)
Stretching/Drawing ( improving strength and crystanillity)
Texturing/Crimping ( developing natural fibre properties)
Intermingling/Interlacing (applied instead of twisting)
Heat setting (made dimensionally stable)
Cutting: According to requirements.
Flow chart of Man Made Fiber production
14. The conversion of polymer into fibre is called spinning. The fibre forming
substance is made temporarily fluid, extruded through spinneret and then
returned to solid state (by solidification) in fibre form
Three types of spinning process:
– Melt spinning (Synthetic).
–Wet spinning.
– Dry spinning.
MAN MADE FIBRE SPINNING
16. PARAMETERS MELT SPINNING DRY SPINNING WET SPINNING
Process The process of spinning by
which fibre or filament is
produced from melted
polymer chips by extruding
through spinneret
continuous filament
produced here.
In dry spinning, the fibre
forming polymer dissolved
in a volatile solvent is
introduced into a heated
drying chamber where the
solvent is evaporated and
solid fibre is obtained
through spinneret
In wet spinning the dope
is extruded through
spinneret and in contact
of coagulant cellulose is
regenerated.
Solvent Not Required Only volatile organic solvent Both organic or non
organic solvent can be
used

SPINNING DIFFERENCE
17. DRY JET WET SPINNING
Dry jet wet spinning is a modification of wet spinning, where the spinneret
is kept just outside the surface of coagulation bath. In this case, the fibre is
extruded into air/gaseous environment and then is pulled inside a
coagulation bath
Example : Meta-aramide Fibre (Kevlar, Nomex)
General Characteristic of Meta-aramide
Fibre :
•Good resistance to abrasion
•Good thermal insulation
•Nonconductive under normal condition
•No melting point, degradation start from
500◦C
•Low Flammability
•Good Fabric integrity at higher temp Dry – Jet Wet Spinning Process
20. WEAVING
• Interlacement of yarn is called Weaving

27. Shedding
To Separate the warp thread in to
two layers, one is raised and other is
lower
Picking
To insert weft thread across the
warp through shed
Beat Up
To push the weft yarn that has
been inserted across the warp ,to
the fell of the cloth

29. Take Up Motion
To draw the fabric to the
cloth roller regularly as it
woven, maintaining the pick
density and pick spacing
through out the cloth
Let-Off Motion
To regulate the amount of warp
delivered from the warp beam
during weaving
To maintain the necessary
tension upon the warp
To influence the number of picks
per unit space in a fabric being
subsidiary to take up motion

32. WET CHEMICAL PROCESSING OF TEXTILE
There are three step of wet processing sector
Preparation process Coloration process Finishing Process
These process ensure
that textile have the
right physical and
chemical properties to
enable them to be
colored or finished
Examples:
Singeing
De-sizing
Scouring
Bleaching
Heat Setting etcs .
The processes exist to
provide the textile with
color either for
aesthetic reasons or
for some functional
purpose determined by
the product
Examples:
Dyeing
Printing
These processes exist
to provide the textile
with the properties that
the end- use demand
and which have not
already been provided
by any earlier process.
Examples:
Starch Finish
Resin Finish
Water Repellent
Flame Retardant
33. Dyestuff is organic or inorganic substances which can absorb light
and reflect some lights to show color . Actually the dyestuff is water
soluble substance
Pigment is a substance that can absorb light and reflect some light to
show color but it is water insoluble substances. Normally it is used for
printing(with the presence of binder) or mass –coloration of the
synthetic fibres
Mechanism of Dyeing:
1. Moving of dyestuff from dye bath to surface of fibre
2. Adsorption of the dyestuff into the surface of the fibre
3. Diffusion of dyestuff in to the interior of the fibre

35. Dyeing process can be applied in many stages such as :
CLASSIFICATIONS OF DYEING PROCESS
1.Mass coloration method is for dyeing of molten
fibre or plastic chip or textile polymer with pigment
dyes. After that the molten or polymer will extrude
from a spinneret to form fibre
2.Fibre Dyeing is method of dyeing fibre dyeing
before it blend with other color to giver fancy
yarn or fabric
3.Yarn Dyeing is a method of dyeing yarns in hank
form s or package dyeing. This is used in
handloom weaving
4.Fabric Dyeing is the method after weaving,
knitting or non woven to make fabric. This is
very popular method of dyeing as the dyed
fabric will be processed further to garment
industries easily.

38. What is Printing ?
Printing is a branch of dyeing and is generally defined as the “
Localised Dyeing” i.e dyeing which is confined to certain portion
of the fabric that constitute the design
Defined as the application of dye or pigment in a different
pattern on the fabric and by Subsequent after treatment of fixing
the dye or pigment to get a particular design
In cotton , dye likes vat, reactive are used
In man made , dye likes disperse and cationic

39. In printing style means the manner in which a printed effect
produced
There are three approaches to printing a color on fabric:
1. DIRECT PRINTING
2. DISCHARAGE PRINTING
3. RESIST PRINTING
DIFFERENT STYLE OF PRINTING
40. In this type of printing dye is applied on to the fabric by craved block,
stencil, screen, Engraved roller etc.
The Dye is imprinted on fabric in paste form and any desire pattern may be
produced
Example : Block printing, Roller Printing, Screen Printing
DIRECT PRINTING
41. In this method the fabric is dyed and then printing with chemical that
will destroy the color in designed area.
Some time the base color is removed and another color printed in its place

43. In this method bleached fabric are printed with a resist paste ( a resinous
substance that cannot be penetrated when the fabric is immersed in a dye .
The dye will only affect the parts that are not covered by the resist paste.
After the fabric has passed through a subsequent dyeing process the resist
paste is removed leaving a pattern on a dark background

47. Fabric finishes are used to improve the fabric in some way. This could be:
Improve appearance - color, pattern
Change the texture of fabric - embossing, brushing/ smoothing
Improve the feel- softer, crisper, firmer
Improved wearing qualities- crease recovery, waterproof, flame retardant
Provide aesthetic value
Soften fabric or change the hand
Add to durability
Adds to comfort
Provide safety
Improves performance
Why are fabric finishes used ?
What Finishing Do?
48. CLASSIFICATION OF FINISHES
Finishing mainly falls in to three category -
1.Temporary Finish: not stable goes off after 1st wash
Mechanical – Calendring , Embossing etc
Chemical – Starching, Softening (except reactive softener)
2.Permanent Finish : Not effected or disappear through out all condition
Mechanical – Sanforizing , Milling,
Chemical - Resin finish, water proof, FR finish
3.Semi- Permanent : stable not more that 5 to 10 washes
Mechanical – Schreiner Calendring
Chemical - Buckram finish
49. FLAME RETARDANT FINISH
FR finishes provide textile with an imp performance characteristic that is it
stopped the propagation of fibre when it comes in contact with fire

the production of flames to prevent the spread of fire
Element of FR finish:
1. Bromine, Phosphorus, Nitrogen &
Chlorine
2. Inorganic Compound
Process:
Pad – Dry- Cure
50. WATER REPELLENT FINISH
Characteristics:
