Properties: Appearance Ionic Nature pH Composition Solubility Compatibility
: : : : : :
Transparent liquid Non-ionic 2.5 Âą 0.5 Blend of ethoxylated alcohols Miscible in all proportions in water. Compatible with anionic, cationic & nonionic products & preparation / bleaching chemicals.
Benefits: Smoother running of ropes, less floatation leading to fewer tangles and more efficient pump performance. Uniform extraction of oil and waxes providing consistently clean foundation for level dyeing and whiter whites. Improved reproducibility Cost savings by improved overall dye processing Trouble free liquid dispersing Low dosages required. Minimised organic pollutant load on dye house effluent. Features: Has excellent emulsifying and soil suspending properties with sustained low foam character throughout heating, cooling and rinsing cycles. Excellent emulsifying properties for knitting and weaving lubricants, oils and waxes.Very good soil suspension and anti-re-deposition properties. Very high detergent action, which ensures rapid removal of synthetic sizing agents and spinning oils from polyester and polyamide based fabrics. Eliminates the need for defoamers /anti foaming agents. Free flowing liquid form. High active content. Low odour – no unpleasant smell. Extremely high primary biodegradability and is readily bio-eliminable. Stable to hard water, acids and oxidizing agents and in caustic alkali upto 50 g/l concentration.
2 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 hosierySet 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 fabricSet 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 fabricSet 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. Combined preparation scour-bleach on cotton hosiery and terry-towelling on winch or soft-flow machinesSet 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 and raise to 90-95ยบC in 20 mins. Maintain the temperature for 60-90 mins., cool to 70ยบC and drain. Rinse in a fresh bath for 10 mins at 6070ยบC 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-BoxImpregnate 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 100ยบC for 90 mins followed by wash-off at boil. In Continuous KierThe process is carried out at 90-95ยบC 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 โ 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 60ยบC to quench residual peroxide, followed by acidification to maintain pH at 6-6.5. (ii)
