Altranol GEO.Natural Clay based cotton pretreatment

  1. 2. Minerals <ul><ul><li>The most widely known mineral in the textile industry is sodium silicate as a mineral stabilizer for hydrogen peroxide bleaching </li></ul></ul><ul><ul><li>L.N.’s challenge: look for other minerals with the good properties of sodium silicate and with success!! </li></ul></ul><ul><ul><li>Clay minerals have been selected on the specific characteristics and formulated in new auxiliaries for the textile industry </li></ul></ul>
  2. 3. A selection of high quality minerals for excellent results <ul><li>In hydrogen peroxide bleaching, both continuously and discontinuously </li></ul><ul><li>In continuous desizing of synthetics </li></ul><ul><li>In post scouring reactive dyed and printed cellulosics </li></ul>
  3. 4. <ul><li>Amongst the big number of minerals, clays have </li></ul><ul><li>very useful characteristics for textile </li></ul><ul><li>applications </li></ul><ul><li>Some clay-classifications: </li></ul><ul><li>Kaolin (Aluminium: “China clay”) </li></ul><ul><li>Semectite (Aluminium + Magnesium) </li></ul><ul><li>Hormite (more Iron) </li></ul><ul><li>Some exceptional properties of clay: </li></ul><ul><ul><ul><li>Thickening agents in paints </li></ul></ul></ul><ul><ul><ul><li>Oil and dirt absorber </li></ul></ul></ul><ul><ul><ul><li>Absorber of inks in e.g. paper industry </li></ul></ul></ul><ul><ul><ul><li>Stabilizer for hydrogen peroxide bleaches </li></ul></ul></ul><ul><ul><ul><li>Softening agents in household products </li></ul></ul></ul>CLAYS
  4. 5. CLAYS
  5. 6. <ul><li>All these classes (and many sub-classes) have different characteristics </li></ul><ul><li>Because of this different special industrial applications e.g. paper coating </li></ul><ul><li>In the past clays were used by Indian and Egyptian women to clean and smoothen their faces and to shampoo their hair. Clay masks and still popular! </li></ul><ul><li>The clay structure is based on sheets </li></ul><ul><li>By separating these sheets e.g. by stirring, a very big surface is created </li></ul><ul><li>This surface (till 800 M 2 per gram) makes it possible to absorb all kind of components like dirt, oil, greases etc. </li></ul><ul><li>This gives an unique detergency effect </li></ul>CLAYS
  6. 7. CLAYS
  7. 8. CLAYS <ul><li>Clay mainly consists of SiO 2 and Al 2 O 3 </li></ul><ul><li>Other ions may be present Mg, Ca, Fe, Li, Mn,….. </li></ul><ul><li>Some clays can stabilize H 2 O 2 bleaches </li></ul>
  8. 9. <ul><ul><li>One of the new applications for clays is as a one-shot product for the discontinuous bleaching applications </li></ul></ul><ul><ul><li>It is based on this mineral technology </li></ul></ul><ul><ul><li>A clay based multifunctional auxiliary for the discontinuous bleaching of cotton with hydrogen peroxide on jets, winches and overflows </li></ul></ul><ul><ul><li>Prescouring of PES/EL and PA/EL </li></ul></ul><ul><ul><li>Alternative for the ecologically unfriendly hypochlorite bleach </li></ul></ul>ALTRANOL-GEO
  9. 11. <ul><li>Excellent hydrogen peroxide stabilizer </li></ul><ul><li>Unique wash performance </li></ul><ul><li>Good wetting out of the fabric </li></ul><ul><li>Excellent lubrification properties </li></ul><ul><li>Low foaming; no defoamer required </li></ul><ul><li>Ecologically very friendly </li></ul><ul><li>Gives fabric a smooth handle </li></ul>ALTRANOL-GEO
  10. 12. Why Should One Use Altranol GEO <ul><li>Altranol GEO allows almost 35% reduction in the BOD & COD levels in the wash effluent </li></ul><ul><li>Altranol GEO further reduces the COD/BOD levels by eliminating/reducing the need for additional auxiliaries in treatment baths i.e. wetting agents, chelating agents, surfactants, lubricants & defoamers. </li></ul><ul><li>The effluent of treated textiles is easily & readily treated by flocculating, precipitating or filtering the natural clays & its adsorbed /precipitated contaminants, which are removed by any standard separation technique like filtering etc. </li></ul><ul><li>The resultant effluent is significantly more environmentally acceptable than current effluents containing organic components & inorganic contaminants. </li></ul>
  11. 13. Why Should One Use Altranol GEO <ul><li>Altranol GEO, besides reducing pollution due to lower BOD & COD levels, also results in lower volatile organic chemicals(VOC’s) </li></ul><ul><li>Altranol GEO is an outstanding lubricating agent providing a softer hand for treated textile goods </li></ul><ul><li>Altranol GEO is non-foaming & extremely effective in removing processing oils & excess auxiliaries & other impurities from the substrates. Treated substrates are cleaner which improves dyeability & dye penetration resulting in increased colour yields of 10~30% </li></ul><ul><li>Altranol GEO is suitable for processing all textile materials i.e. all fibres, filament, yarns, fabric & all products made from them. They include textured & non textured filaments & yarns, woven, knitted or non-woven fabrics. </li></ul>
  12. 14. <ul><li>Bleach for dyeing indication recipe: </li></ul><ul><li>95-98ºC during 20-30 minutes: </li></ul><ul><li>1-2 ml/l Altranol-GEO </li></ul><ul><li>2-3 g/l Caustic flakes </li></ul><ul><li>2-5 ml/l Hydrogen peroxide 35% </li></ul><ul><li>Neutralize peroxide with Quench-PN </li></ul>ALTRANOL-GEO
  13. 15. <ul><li>Bleach for whites indication recipe: </li></ul><ul><li>1-3 ml/l Altranol-GEO </li></ul><ul><li>2-3, 5g/l Caustic flakes </li></ul><ul><li>6-10 ml/l Hydrogen peroxide 35% </li></ul><ul><li>X % Optical brightening agent </li></ul><ul><li>95-110ºC during 90-30 minutes </li></ul>ALTRANOL-GEO
