Fibers are the smallest elements that make up textile materials. Cotton is a natural fiber obtained from cotton plants, which belongs to the genus Gossypium. Cotton can fulfill 42% of global fiber demand and is produced in countries like the USA, China, India, Australia, and others. The blow room is the first processing section, which opens, cleans, blends, and mixes cotton fibers using machines like the bale opener, cleaner, and mixer to remove 40-70% of impurities. Carding further processes the fibers to individualize them and remove neps and short fibers in preparation for spinning. It drafts and orientates the fibers using components like the taker-in, cylinder, flats

27.  An efficient blow room process accomplishes the
basic objectives such as opening , cleaning ,
mixing of cotton without increasing fiber rupture ,
fiber nep and broken seed particles and extracting
more amount of trash without good fiber loss.
Parameter are listed below :
 Speed of the beater
 Speed of the feed roller , feed type
 Number of beating point , type of beater
 Beater to grid bar setting , grid bar angle
 Pneumatic air velocity
 Ambient condition

28.  Carding is defined as the reduction of entangled
mass of fiber to filmy web by working them
between two closely spaced relatively moving
surface closed with sharp points.
 Well carded is called half of spun . Carding is a
mechanical action of reducing tufts of entangled
fibers into a continuous web of individual fibers
suitable for subsequent processing.

29.  Individualization of fibers.
 Cleaning the fine trash particles that are not
removed in blow room.
 Removing neps and short fibers.
 Fiber blending.
 Drafting and orientation of fibers

31. Feed region
 To hold the flock securely over its full width.
 To hold the material back against the action of the
taker in .
 Setting between feed plate and taker in is around
.45-.7 mm.
Taker in
 In taker in where fiber are first opened in individual
stage.
 Taker in diameter is around 250 mm
 The disposition angle of the motes knife is
important , which influence on cleaning intensity.

32.  Amount of draft between taker in and feed
plate is around 1000.
 Now days three taker in are used for coarse &
more trashy cotton.
 Remove the impurities.
 To perform as a primary cleaning and
opening device.

33. Cylinder:
 It caries the fiber action with flat.
 Carding action means to separate fiber from
one to another.
 Cylinder diameter around 1200-1500mm.
 Cylinder rotate at 450-550 rpm.
 Amount of draft between cylinder ant taker in
is around 1.5-1.75

34. Flat:
 The top flat carried out an endless chain , they
move continuously forward to working area.
 Opening the flock to individual fibers.
 Elimination the remaining impurities.
 Number of flat is 74 to 120 ,continuously working
at 35 to 42.
 Flat speed is 8-20 cm/min

35. Doffer:
 Surface speed is 10-20 times less then cylinder .
 Primary function of doffer is collect the fiber from
cylinder and it is carry to calendar roller.
Precarding & postcarding segment:
 The carding zone essentially consists of precarding and
postcarding section.
 Precarding segment are installed in the feed side and
postcarding segment are installed in the deliver side .
 Both segment are improved cleaning efficiency of the
card by facilities the removal of motes , seed coat
fragment and dust.
