    • LNC Technical Information TDS-P-52 ALTRANOL-EPLFDescription:Is a low foaming, high performance detergent designed for the preparation of cotton,synthetic and blended fabrics in machines of high liquor turbulence such as jet, soft flow andpackage dyeing machines as well as in continuous processing systems.Properties: Appearance : Transparent liquid Ionic Nature : Non-ionic pH : 2.5 ± 0.5 Composition : Blend of ethoxylated alcohols Solubility : Miscible in all proportions in water. Compatibility : 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.
    • 2Application :Due to its powerful detergent activity and low foam property Altranol-EPLF advantageouslyreplaces conventional scouring surfactants employed in batchwise and continuouspreparation processes Altranol-EPLF allows significant improvement in productivity. It isparticularly useful in single-stage combined desize/scour/bleach operations for woven andknitted fabrics, terry-towelling and yarn packages.On polyester-based fabrics, removal of synthetic sizing agents (especially acrylates which areused 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 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 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 Caustic Soda solid 15-25 g/l MODSTAB-MS 7-10 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.Storage: Good shelf life under normal storage conditions. Containers must be tightly closedwhen not in use.Packing: 30, 50, 100 & 200 kg HMHDPE containers.The information in the datasheet is based on our present state of knowledge & is published without any obligation on our part.
