spinning departments in full quantity at required time. The
minimum cost meeting all quantity parameters. The department
is responsible for the conversion of the dyed and grey tops to
recombed tops.
Objective Of The Department
 Blending of the fibre like Wool viscose, polyester, Lenin silk, etc.
 Removal of short fibre and undesired element like slubs, neps,
and pin point.

22. SPINNING

23. SPINNING
ROVING
 This is the final stage before spinning.
 Roving is actually a light twisting operation to hold the thin
slubbers intact.
Objectives of roving
 To produce wrapping (wt/unit length) as per requirement.
 To produce a package suitable for subsequent machine.
 To make uniform length in each package as per requirement
of next machine for proper run-out.
 It removes unevenness of yarn for further process.

24. SPINNING
Ring Frame
Ring spinning is a method of spinning fibre to make a yarn. Ring
spinning is a continuous process . In ring spinning, the roving is first
attenuaed by using drawing rollers, then spun and wound around a rotating
spindle which in its turn is contained with in an independently ring flyer.
Objectives of ring frame
 To produce single yarn of required twist and count as per the instruction
from ppo.
 To produce good quality of yarn
 To make ring cops means of building mechanism.
 The rubbing and roving frame bobbins are brought to ring frame dept the
roving is converted into yarn by drafting and twisting.
 All the three types of yarn made in ring frame.
ex:- Normal Yarn, Sarrow Yarn , Sarrow Lycra Yarn

25. SPINNING
Factors for promoting good spinning
 Count of yarn.
 Position of spindle rate.
 Correct type travellers.
 Satisfactory spindle speed.

26. AUTO WINDING
SECTION
Objective of auto winding
 Removal of objectionable yarn faults such as thick, thin place and
neps, to improve the yarn quality and subsequently reduce yarn
breakage in further processing.
 Rewinding of ring frame cops to a larger package, which is useful for
further processing.
 Auto-leveller sensor is attached which removes the shorts term
variation and medium term variation
 Online sensor passed through which gives signal for removal of fault
in the yarn

27. Doubling section
 Ply winding:- Assembly of two yarns are wound parallel as per
requirement such as solid to make the feed package for TFO
machine.
 Two for one twister:-To insert the required twist in required
direction (s/z).

28. WEAVING
 Weaving is the term used in relation to produce fabric by interlacing two
different series of yarns known as warp and weft. Warp ends are placed
longitudinal where as weft are horizontally placed. Weaving process is
commenced by dividing warp into two different sheets in opposite
direction and then inserting weft into the shed. By interlacing it into the
shed fabric is produced.
 There are total 112 looms, which includes 34 Picanol Gamma, 56
Nuovo Pignone (NP) and 22 Picanol Gammax looms.
 The total output of this department is 23000 meters per day.
 The machines are running with speed of in between 450-530 rpm.

29. Weaving section is divided into two sections.
 Warping
 Weaving
Warping: The yarns which are coming from double yarn room are going for
winding for preparing required amount of package.
Three primary process of weaving.
 Shedding- The process of separating the warp yarn into two layers by
raising the harness to form an open area between two sets of warps and
known as shed.
 Picking- The process of inserting the filling yarn through the shed by the
means of the shuttle less while the shed is opening.
 Beating- The process of pushing the filling yarn into the already woven
fabric at a point known as the fell and done by the reed.

30. Rapier loom
 In Rapier looms, the weft insertion element resembles a rapier or a
thin bladed straight sword, hence the name Rapier Weaving. There
are many varieties of Rapier systems such as single, double,
flexible, rigid, and two phased. A Rapier in its simplest form consists
of a single rigid bar, solid and a damp device called gripper head
screwed at its feed end.
 Manufacture name - Picanol Gamma,
Picanol Gammax looms
Nuovo Pignone (NP)
 No. Of machine - 112
 Input type - yarn
 Output type - fabric

31. Defects during weaving

32. FINISHING DEPT.
 Finishing department is the place where final treatment is done to
the fabric.
 It includes washing, drying and application of some chemical and
mechanical treatment to the fabric to make it aesthetically appealing
and add features to the fabric.
 The finishing dept. at Raymond Chhindwara has three sections, i.e. ,
grey room, wet section and dry section.
 Finishing dept. at Raymond Chhindwara is equipped with modern
machinery for washing, scouring, singeing, pressing etc.

33. Flow chart

34. The processes carried out in finishing dept are :
 Mending: To remove defects like knots formed during weaving.
 Batching: shortening each beam of fabric according to shades.
 Singeing: The fabric is exposed to flames and made to pass through it.
 Pre scouring: Extraction of dust and other particles.
 Drying: Fabric is dried in a chamber of temp 170*C.
 Heat set: Fabric is passed through a heated chamber of temp 185-190*C.
 Rope scouring: Scouring is done in rope form.
 Softening: To remove the harshness of fabric by adding softeners like
silicon in the solution.
 Pressing: It is done to remove wrinkles and make the fabric smoother.
 Decatising: To remove excess of lustre and prepare the fabric for pressing
and cutting.
