Introdu"tion

• Dyeing is the process of imparting coloursto a textile material in loose bre, yarn,cloth or garment form by treatment with a

dye.• Dyeing can be done during any stage.

•  Textiles may be dyed as bers, yarns,fabrics or as garments.

• It occurs in the most ecient stage whichwill meet the requirements of the intendedend users.

• According to the dyeing process used

S&ray Dy%ing Ma"hin%'• Dened as an improed ersion of

roller dyeing machines or hybrid typeof machines with combination offeatures of roller dyeing and cabinetdyeing.

• &ade of rectangular shaped box type

enclosed main body, in which thespray arms are located, there iscollection tan( with heating coils atthe bottom.

•  These machines hae remoableloading arms, same as in rollerdyeing machines ,but haingperforations for spraying the dyeliquor from inside the rollers.

•  These arms hae an arrangementalso tted with suitable spray pipesfor spraying the dye liquor from

Hank dy%ing ma"hin%•

 These machines are designedto hae liquor *ow parallel tothe yarn

•  They wor( with low liquorratios to sae substantially in

consumption of thermalenergy ,water and chemicals.

•  The liquor circulation and*ow remains the same as inordinary cabinet machine.

•

 The dye liquor in thesemachines moes while thematerial remains stationary.

•  The *ow direction is reersedfrequently to ensure leel

dyeing.

H(HP dy%ing ma"hin%'

• In this process the system isconerted into a totally enclosed'T'+ system. +ressure is generatedby means of a power circulationpump and arranging closed steamcoils. This raises the temperature ofthe dye bath. Increase of steampressure creates a high temperature.

• In the case of synthetic and blended

yarns, the temperature is raised up to"$- . In extreme cases, there areproisions to hae temperatures upto "/0-.

• It was only after the adent of the synthetic bres thatdyeing recipes recommending high temperaturesbecame quiet common and hence the machinesbrought out later were suitable uniersally, for normalas well as high temperatures.

• 1sed in treating bobbins, loose bre, yarn, cotton,

polyester, wool, acrylic, nylon, iscose and more.•  The machines are designed for low liquor dyeing

process at a liquor ratio of "#.$ to "#2.

S&a"% Dy%ing Ma"hin%

• In this type of machine up to 3

colors, can be dyed, each colorhaing a di4erent feed tan( as wellas in5ector pump .

•  The color is in5ected at a xedplace at high pressure and

collected through acuum.•  This type of machine is used to

create beautiful patterns of dyedpatches on pac(ages , with goodsharpness.

•6pace dyeing in han( form is asimpler process to produce tie diee4ects in the (nitting yarns andembroidery threads.

•  The yarn printing process or The

warp system•  The (nit7de7(nit process.

B%am dy%ing ma"hin%•

A machine for dyeing yarns orfabrics that hae been wound ontoa special beam that has eenlyperforated holes along its barrel.

•  The dye is forced through the barrelinto the yarn)fabric from inside tooutside and ice ersa

•  The fabric or yarn hae betterdyeing results because there is nodimensional changes as well asthere is no mechanical force appliedto it.

•  The high performance pumpscirculate the dye liquor in ecientmanner to achiee een dyeingresults.

 )igg%r dy%ing ma"hin%'•

 Two main rollers running on smooth rollersand can be reersed.

•  The fabric moes from one of the mainrollers, and passes through the dye trough.It9s a series of intermittent paddingoperation.

•  The fabric from the main roller passesthrough the dyebath and ta(en up byanother roller on the other side.

• :hen all the fabric has passed, the direction

is reersed.•  The temperature is maintained by a

perforated pipe at the bottom of the trough,across the width of the 5ig that in5ects liesteam.

•

 )%t Dy%ing Ma"hin%'

•

A machine used for dyeing of fabric inrope form.

•  ;et dyeing is a process that can be usedfor batch dyeing.

• 'ere dyeing is done in a closed tubular

system, basically composed of animpeller pump and a shallow dye bath.

•  The fabric to be dyed is looselycollapsed in a form of a rope, and tiedinto a loop. The impeller pump supplies

a 5et of dye solution, propelled by waterand)or air, which transports the fabricwithin the dyeing system, surroundedby dye liquor, under optimumconditions.

• an be operated een at hightemperatures and pressures.

Paddl% Dy%ing Ma"hin%'• A process of dyeing textiles in a machine

that gently moes the goods usingpaddles similar to a paddle wheel on aboat.

• 6low process, but ery little abrasion onthe goods.

•

'ori=ontal paddle dyeing machineconsist of a cured bec( li(e lowersuction tocontain the materials and the dye liquor.

•  The goods are moed by a rotating

paddle, which extends across the widthof the machine.

•  The temperature can be raised up to>3o in such system.

• !ateral ) oal paddle machines consist of

oal tan( to enhance the *uid *ow andthe processing the of the goods.

• :or(s on the principle ofmoement of textile material anda stationary liquor.

• onsists of a rotating perforatedcylindrical drum , which rotatesinside a essel.

• 'igh temperature drum machinesare capable of processing thegarments up to "/0 degreeelcius.

• Also called ?multipurpose drum

machines@ or ?multi7rapid dyeingcentrifuging machines@

• an operate at ery low liquorratios.

• 6uitable for (nits as well as othergarments.
