use of steaming in textile processing machinery

UNDER THE GUIDANCE OF
(Dr.) USHA SAYED

Introduction
 Steaming is one of the most important processes in textile processing
such as well as being widely used in pretreatment, dyeing, finishing and
printing processes has come a long way from its traditional associations
with locomotives and the Industrial Revolution.
 Steam today is an integral and essential part of modern technology.
Without it, our food, textile, chemical, medical, power, heating and
transport industries could not exist or perform as they do.
 Steam provides a means of transporting controllable amounts of energy
from a central, automated boiler house, where it can be efficiently .

Reasons for using steam
 Steam is efficient and economic to generate
 Steam can easily and cost effectively be distributed to the
point of use
 Steam is easy to control Energy is easily transferred to
the process
 The modern steam plant is easy to manage Steam is
flexible

BEN-BLEACH
Pretreatment system Desizing, scouring and bleaching in one single run
 In the REACTA steamer the chemicals react with the fibers themselves
and the accompanying substances.
 The combination steamer with tight strand cloth run and plaiting on a roller
bed permits reaction times of 1 to 60 minutes.
 An automatic steam conditioning and regulating station guarantees
constant conditions and an air free atmosphere.
 An absolute must for high pretreatment quality.

REACTA – Modular steamer and retention accumulator
 Crucially important to any continuous pretreatment range is the steamer.
Here especially therefore, economy and flexibility must be combined in
optimum fashion.
 The building block system devised by Benninger enables a steamer ideally
suited to industrial requirements to be assembled for any duty from proven
basic modules.
 Alternatively used as a steamer, or retention accumulator for soaping, with
spray water circulation and saturated steam atmosphere

Crease free operation is a matter of course
Fabric inlet
 The cloth is let into the steamer through a steam lock, guided over big drive rollers and
brought at once to the reaction temperature.
Steamer draw-off section
 While still in the steamer, the fabric is drawn off over a short distance to the appropriate
guiding elements, expanded and centered fed into the steamer outlet with water lock to secure
steam tightness.
 Both counter current and high temperature generate the high washing effect. Liquor
separation is created by the pulling device at the exit.

BEN-COLOUR
 The advantages of the continuous dyeing process and the flexibility of a small size range
are here combined! EXTRACTA-BECOFLEX compartments are utilized for post
treatment
Possible applications
 PAD-STEAM process for vat and reactive dyestuff (PAD-DRY is carried out in a separate
range)
 1-bath (all in) PAD-STEAM process with sulfur dyestuff (cotton)
 2-bath (wet/wet) PAD-STEAM process vat dyestuff (cotton)
 1-bath (all-in) PAD-STEAM process with reactive dyestuff (cotton)
 2-bath (wet/wet) process with direct dyestuff (cotton)
 ARTDENIM ring dyeing process with reactive or sulfur dyestuff

 Bifunctional dye steamer for reproducible
 Constant saturated steam conditions
 Benninger feeds to steam for humidity control through a steam
conditioning station.
 The steamer roof is heated; roof and front and back side are well insulated.
The water lock at the steamer exit is a critical part of equipment for a
successful process. The temperature is controlled via the water feed and
low water volume ensures constant process parameters.
 Automatic cleaning device
 Geometry and drive system ensures crease free cloth run. Tension
differences caused by shrinking or stretching of the cloth in the steaming
process are equalized immediately.
 At the entry of the fabric into the steamer, a lip heating and an exhaust
suction fan for excess steam prevent condensate drops at the entry area.
REACTA

Continuous PAD-DRY -PAD-STEAM Process
Possible applications
 PAD-DRY/PAD-STEAM process with reactive or vat dyestuff (cotton)
 PAD-THERMOSOL/PAD-STEAM process with reactive and disperse dyestuff
(cotton/polyester)
 PAD-THERMOSOL/PAD-STEAM process with vat and disperse dyestuff
(cotton/polyester)

 COLD PAD BATCH dyeing process with reactive dyestuff (cotton)

Universal steamer «DH» / «DHe»
 The Universal steamer type «DH» / «DHe» is equipped with the «UNIVISION» process
controller. This gives it wide adjusting ranges for temperature, humidity, dwell time and fan
speed. Single and serial trials with small material samples are possible with the «DH» /
«DHe».
 High-temperature steaming, i.e. short time curing and setting of printings and pad dyeing in
superheated steam (hydro-dry) within a temperature range of 100 – 250 °C and at a steam
content between 10 and 100%.
 Optional additional components enable treatments in the Econtrol procedure at low steam
content of 25% for reactive dyes.
 Drying, curing and setting at temperatures up to 250 °C.
 Steaming with saturated steam (100 °C).
optional process oriented add-on components
 Econtrol procedure
 MXL procedure
 Infrared radiation pyrometer: enables the exact, current surface temperature and the resulting
residual humidity to be determined.
 Electric steam generator: The «DHe» type is equipped with an integrated electric steam
generator..this makes the «DHe» independent of a steam system. The steam quality is also
constant
 Exhaust steam cooler
 Material holders in various designs

Flash Ager For Two Phase Prints
 Specially designed to wet out the fabric for two-phase steaming.
 Two-phase printing is usually used for women cloths printed with
reactive or vat dyes.
 After printing and drying, the cloth passes through a chemical mangle and
then into a steaming chamber for fixation.
 The machine is complete with chemical pad mangle with two horizontal
rollers particularly suitable for two-phase liquor application.
 One chrome-plated roller contacts the printed side of the fabric whereas a
viscous elastic rubber roller works on the reserve side of fabric.
 Special pneumatic pistons ensure a regular and uniform squeezing.
 For reactive dyes, fixation process requires about 15 seconds at 130°C
 For vat discharge fixation process, it requires 30 seconds at a temperature
of 130°C.

Steamer for Garment
 Steamer for garment has the concept of just like our sample steamer for
fabric. There is a continuous chain on which at the operator can hand the
garments which is already place on hanger, chain is moving with slow
speed according to the process time required.
 After the process is over it comes out at the opposite side where one
person can take out the garment hanged on hanger
 The machine is suitable for dyes like Reactive, VAT, Disperse, Acid and
Pigment. Chamber temperature can be maintain from 102°C to 108°C
for low temperature application, 160°C to 180°C for high temperature
application and 130°C to 160°C hot air for pigments.

Laboratory Loop Ager for Digital Printing
 To develop fabric of any quality like Polyester, Cotton, Viscose and Silk printed
with disperse, reactive, vat and acid dyes.
 Printed fabric of 500mm to 10 meters can be steam in continues fashion in
compact steaming chamber.
 Steam can generate in the chamber itself with the help of electrical heater if
desire or can be supplies team from boiler house and steam can be super
heated by electrical heater or Thermic fluid heater, if oil boiler is available at
site.
 Machine is made up from complete stainless steel, constructed with gear motor
and electric control panel.
 Capacities available : 800 mm x800 mm, 1000 mm x1000 mm

Curing / Polymerizing Machine
 The fixation of dyes on fabric is made by a polymerization in hot air at 150°C.
 Improved the polymerization process on fabric moves in tension-less condition,
there is no rubbing and no lengthwise stretching on printed fabric.
 The machine is essentially built on a steel frame with insulation panels containing
mineral wool. Inside the machine, centrifugal blowers are mounted that suck
surrounding air through a filter and blow into the machine chamber. This blowing is
done from the bottom, underneath the heaters. In this way, the fresh air is first
heated and then mixed with the circulation air.
 Eventually oil condenses or hydrocarbons, which develop during fixation, are
removed through an exhaust fan partially and partially re circulated air-to-air heat
recover within the chamber.
 The fabric transports on free loops, quantity of fabric contain from 50 meters to 250
meters and working fabric width available from 1200mm to 3300mm.
 Deionization bars are installed at the inlet and outlet to reduce the fabric
electrification phenomena.
 Electric control panel is possible to supply logic programmer.
