very thin, bad yarn. The small cops will be feed in to winding ma-
chine to make big bobbins weighing around 2kg. and winding sen-
sors detect the yarn faults.
After winding : For 9Nm and 5Nm - The label will be pasted on eve-
ry bobbin and send to dye house for dyeing. After dyeing process,
the dyed yarn will be subjected to yarn quality test like shades, ap-
pearance etc. & after quality checking we will rewind the dye pack-
age to get big bobbins weighing around 4 kg. bobbins for getting
better efficiency in fabric production. Small package leads frequent
bobbin changes in feeding section of rapier loom but big package
will eliminate frequent changes. For 4Nm - 4Nm yarn is coloured
yarn because raw material itself dyed yarn and this yarn will not be
sent to dye house. The yarn is captively used in their weaving sec-
tion for fabric production.
(g) Poly Propylene Extrusion Yarn : The raw material Poly Propylene
white chips and colored Poly Propylene granules are procured from
outside. The PP white chips will be fed into extrusion machine
along colored granules through colortronics system in the required
ratio. The chips and granules are churned, grinded and melted in
screw and barrel. The semi-solid liquid (melt) will flow through the
pipes in pressure, which are heated by chemical vapour. The melt
will be metered through pump to get the desired denier and it will
be squeezed out in filament from packs. Then it will be cooled by
cool air as well as by natural cooling. After cooling, spinfinish oil is
applied to cohesing the multi-filaments into single yarn form. Air is
applied to distribute spinfinish (1.1kg./Cm ). Thereafter, stretching

through the number of godets and intermingled points are applied
through air (5 kg/Cm ). Finally wound on a paper cone in winder

machine to get the final bobbin weighing around 7.5 Kg., which will
be subject to testing for all properties and the required norms. This
yarn is captively used in the manufacture of fabric. In future, may
go for commercial sales also.
(h) Polypropylene Texturized Yarn : Harmolan 100D - 2 ply - The raw
material Polypropylene fully drawn yarn (450D/144F). The yarn
will be creeled on trolley (Two Bobbin as core only), which will be
threading to the godets through water jets, where water treatment is
given and through air jet, where air jet is blown at 10kg./Cm .
2
Again threading to the godets is carried out. Then it is wound on
paper cone to get the final bobbin weighing around 4 Kg., which
will be subject to testing for all properties and the required norms.
Then it will be graded and packed in boxes and exported. This yarn
is captively used in the manufacture of fabric also.
(i) Polyester Texturized Yarn : Taslan 1100D - 4 ply - The raw material
Polyester Partially Oriented Yarn (350D/96F) from outside. The
yarn will be creeled on trolley (Two Bobbin as core and two bobbins
as effect), which will be threading to the godets. The core yarn will
be passed through water jets, where water treatment is given and
through air jet, where air is blown at 10kg./Cm . The effect will be
2
passed through air jet, where air is blown at 10kg./Cm . All 4 plyed
2
yarn will pass through heater (220°). Again, it will be threaded
