Application :
Due to its powerful detergent activity and low foam property Altranol-EPLF advantageously
replaces conventional scouring surfactants employed in batchwise and continuous
preparation processes Altranol-EPLF allows significant improvement in productivity. It is
particularly useful in single-stage combined desize/scour/bleach operations for woven and
knitted fabrics, terry-towelling and yarn packages.
On polyester-based fabrics, removal of synthetic sizing agents (especially acrylates which are
used to facilitate the weaving operation on water-jet looms) poses a major problem.
Altranol-EPLF expeditiously cleans out such polymers in short treatment times.
A. Batchwise Processing-
(i) Scouring of cotton hosiery-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 – 1.0 g/l
Caustic Soda solid 3.0 g/l
Start at 50ºC, raise gradually to 95ºC and run for 30 mins. Cool to 70ºC.
drain and neutralise with
Acetic acid (80%s) 0.5 g/l
at 70ºC for 10 to 20 mins.
(ii) Scouring of polyester-cellulosic blended fabric-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 – 1.0 gl/
Soda Ash 5.0 g/l
Sodium Perborate 2.0 g/l
Start at 40ºC, raise to 95ºC in 15 min., run for 30 mins. Cool to 70ºC
drain and hot rinse at 70ºC.
(iii) Desize-scour of Polyester or Polyamide fabric-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 1-2 g/l
Soda Ash 5.0 g/l
Run for 30-40 mins at 100ºC for polyester (or 80ºC for polyamide), cool
to 70ºC, drain and wash thoroughly at 70ºC.
(iv) Combined preparation scour-bleach on cotton hosiery and terry-towelling on
winch or soft-flow machines-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 - 1.0 g/l
ECOSOFT-400 0.5 g/l
and load the fabric while raising to 60ºC then add
Hydrogen Peroxide 50% 2.0 -5.0 g/l
Caustic Soda Solid 2.0 - 3.0 g/
MODQUEST-WS/PEROSTAB-BLN or 1.0 - 2.0 g/l
MODSTAB-MS
LUBASSIST-JET 0.5 - 1.0 g/l

3. 3
and raise to 90-95ºC in 20 mins. Maintain the temperature for 60-90
mins., cool to 70ºC and drain. Rinse in a fresh bath for 10 mins at 60-
70ºC with 0.5-1.5 g/l NEUTROX-ALN and acidify to pH 6-6.5 before
draining.
For fabrics to be marketed as white, an initial scouring treatment
followed by the bleaching process (preferably incorporating a
compatible optical whitener) yields optimum results.
B. Continuous Processing-
(i) Single-stage desize-scour-bleach for cotton hosiery and low-sized terry-toweiling
in J-Box-
Impregnate in saturator at 100-120% pick-up with
ALTRANOL-EPLF 1-2 g/l
ECOSOFT-400 2-3 g/l
Caustic Soda solid 4-6 g/l
MODSTAB-MS 5-6 g/l
Hydrogen Peroxide 50% 20-35g/l
and steam at 100ºC for 90 mins followed by wash-off at boil.
In Continuous Kier-
The process is carried out at 90-95ºC employing a liquor ratio of 10:1-8:1 with
fabric treatment for 1 hour followed by a squeeze, and washing-off/souring in
a separate washer. A continual gravity feed maintains the effective
concentrations in the kier-liquor. A full white can be obtained with the
following recipe (percentage on weight of material):
ALTRANOL-EPLF 0.5 - 1.0%
ECOSOFT-400 0.5 – 1.0%
MODSTAB-MS 1.0 - 2.0%
Caustic Soda solid 1.0 - 1.5%
Hydrogen Peroxide 50% 3.0 - 5.0%
alongwith a compatible optical whitener. For fabric to be subsequently dyed,
NEUTROX-ALN may be added in the washer at 60ºC to quench residual
peroxide, followed by acidification to maintain pH at 6-6.5.
(ii) Desize-scour-bleach on Pad-Steam range-
Desize by padding at 60ºC and 80-100% pick-up with
ALTRANOL-EPLF 1 g/l
Enzyme desizing agent 2 g/l
and roller-bed steam at 98-100ºC for 10 mins. followed by wash-off at 80ºC.
Scour by padding at 85ºC and 80-100% pick-up with
ALTRANOL-EPLF 3-5 g/l
Caustic Soda solid 10-15 g/l
and roller-bed steam at 98-100ºC for 10 mins followed by thorough wash-off at
boil. Bleach by padding at room temperature and 80-100% pick-up with
ALTRANOL-EPLF 3-5 g/l

4. 4
Caustic Soda solid 10-12 g/l
Modquest-WS / Perostab-BLN 4-5 g/l
or MODSTAB-MS
Hydrogen Peroxide 50 15-20 g/l
and roller-bed steam at 98-100ºC for 3 mins. followed by thorough wash-off at
near boil.
Alternatively, a combined single-stage preparation can be employed for low-
sized grey-
Pad the fabric at room temperature at 80-100% pick-up with
ALTRANOL-EPLF 5-7 g/l
Caustic Soda solid 12-15 g/l
ECOSOFT-400
MODQUEST-WS / PEROSTAB-BLN 5-8 g/l
Hydrogen Peroxide 50% 40-60 g/l
and roller-bed steam at 98-100ºC for 15 mins. followed by thorough wash-off at
near boil.
(iii) Desize-scour-bleach by Cold Pad-Batch for woven cotton and polyester-cotton
fabrics-
Desize by padding at room temperature and 80-100% pick-up with
ALTRANOL-EPLF 2-3 g/l
Enzyme desizing agent 5-10 g/l
and batching overnight at room Temperature followed by thorough
wash off at boil,
Scour-bleach by padding at room temperature at 80-100% pick-up with
ALTRANOL-EPLF 5-8 g/l

Hydrogen Peroxide 50% 30-45 g/l
and batch at room temperature for l5-24 hours followed by thorough
wash-off at boil.
