  • 1. Green SolutionsMineral Technology in Textile Processing andWater Saving Program
  • 2. HistoryTANATEX Chemicals strongly believes in the use of minerals intextile processing. Over the years we have successfully launchedproducts like: TANNEX® GEO – Multi-functional product for pretreatment, dyeing and correction of faulty finishing TANNEX® NOVECO – Multi-functional product for pretreatment, dyeing and correction of faulty finishing TANATERGE® ELB – Nano-clay based composite for the pre- treatment of elastane blends TANASPERSE® MDA – Mineral desizing agent for PA & PES TANATERGE® M-RE – Mineral soaping agent TANNEX® RENA liquid 01 – Ecological stabilizer for hydrogen peroxide of an extraordinary quality Green Solutions. Slide <2>
  • 3. TANNEX® NOVECO Multi-functional product for pretreatment, dyeing and correction of faulty finishing
  • 4. TANNEX NOVECO Clay-based multi-functional agents• Clay is a so-called layered aluminosilicate of extremely small particle size• In water these particles are hydrated and they possess a negative charge.• There are many clay types, depending on their chemical structure and deposit area• e.g. Kaolinite, Vermikulite, Smektite, Illite• The clay used in TANNEX NOVECO has largest surface of approx. 800 m²/g Green Solutions. Slide <4>
  • 5. TANNEX NOVECO Scheme of a clay particle • The negatively charged particles have a large potential adsorption surface for:•(-) •(-) •(-) – hydrophilic materials and •(-) •(-) •(-) polymers •1 nm – hydrophobic waxes and oils – metal ions •200-10.000 nm • Excellent stabilising effect for H2O2 • Very good lubrication to prevent crease marks Green Solutions. Slide <5>
  • 6. TANNEX NOVECO Absorption of impurities/dirt Absorption of clay on oil Fat and impurities Clay sheetsGreen Solutions. Slide <6>
  • 7. TANNEX NOVECO The Stabilizer Concept Traditional Organic Stabilizer TANNEX NOVECOGreen Solutions. Slide <7>

TANNEX NOVECO Special Application• Stripping fluorcarbon & silicone finishes 1 ml/l DIADAVIN HLS Conc. 01 3 – 5 ml/l TANNEX NOVECO 3 – 5 ml/l Caustic Soda 50 % – repair at 90 – 100 ºC during 40 – 50 minutes – rinse thoroughly with warm & cold water – repair the dyeing (if required) and apply finish again Green Solutions. Slide <8>
  • 9. TANNEX NOVECO Special ApplicationPrevent the deposit of oil and As an lubricant in dyebath oligomer on machine Due to its absorption – TANNEX NOVECP shows properties the machines are excellent lubricant kept perfectly clean. Some properties on all cellulose polyester dyers use based fabrics and knits, e.g. Cotton, Viscose, Modal, 0,5 ml/l TANNEX NOVECO Polynosic and especially Lyocell fibres and give them To avoid soil and dyestuff a nice soft handle deposits in their machines – Also on synthetics good To remove the knitting oil results are being obtained from the fabric. Cleaning operations can drastically be reducedGreen Solutions. Slide <9>

  • 12. TANNEX® NOVECO Environmental awareness TANNEX® NOVECO is the answer for environmentally responsible textile processing. TANNEX® NOVECO is harmless for the aquatic environment, shows a high biological elimination (>70%) and is therefore not dangerous for all in water living species.TANNEX® NOVECO is our next step in sustainable textile processing. Green Solutions. Slide <12>
  • 13. TANNEX® NOVECO Positive effect on COD and BOD5Some practical measurements in a textile factory, which clearlyshowed the decrease of COD and BOD figures.Average reduction of COD values: 25%Average reduction of BOD values: 53%The organic substances, as soluble or dispersed substances, areabsorbed by the clay of TANNEX® NOVECO and thus removed fromthe water. Of course biodegradation will continue on the clay.But the cost for discharging this effluent water into communaleffluent streams will be reduced drastically.TANNEX® NOVECO helps you to respond to environmentalissues in a simple way Green Solutions.

  • 36. Water Savings ProgramsSome practical examples
  • 37. Water savings programs• Water shortage is an emerging word in textile processing industry• So everybody wants to save water in their process• A complete new way of thinking is necessary• TANATEX can and will play its part in this new challenge• This presentations will give you some ideas and some practical experiences Green Solutions. Slide <37>
  • 38. Water consumption in average textile company• Total average water consumption per kg textile will be around 45 l/kg, however specific cases are known where up to 100 l/kg will be used. (Information present customer: - 80.000 m production per day @ 400 g/m (32.000 kg) - Total effluent per day 1.500 m3/day (1.500.000 liter) - Total water consumption per day 47 l/kg (1.500.000 liter / 32.000 kg)• Average water consumption in the pretreatment only, will already be around 15 – 20 l/kg. Green Solutions. Slide <38>
  • 39. How does WATER fit in our philosophy ?We promote WATER from different points of view: - less total waste water and less effluent load - cost savings in water and energy - cleaner water by less chemical waste in effluent - specific biological treatments but most important:WE BELIEVE IN WATER ! Green Solutions. Slide <39>
  • 40. Example 1 Continuous bleachGreen Solutions. Slide <40>
  • 41. Less total waste waterEffect of TANNEX RENA liquid 01 Using TANNEX RENA liquid 01 makes it possible to reduce the amount of NaOH to max. 40% of the amounts use for classical organic stabilisers. This could easily result in a water reduction of 2 – 3 l/kg per application (cold pad batch and/or pad steam). Consuming less water directly reduces the energy consumption and therefore strongly reducing costs per kg. Green Solutions. Slide <41>
  • 42. Objective of industrial trials in this example• Optimize washing procedures and reduce total water consumption.• Create a single procedure (desizing and bleaching) for all processes (blanquear and descrudar) in order to replace the two different procedures as for actual standard procedures.• Replace actual alkaline boil off by an enzymatic desizing.• Increase productivity by simplifying procedures and reducing changing times for different procedures.• Create a green and sustainable process based on GOTS approved products, low harsh chemicals (NaOH and H2O2) and reduction of water and energy. Green Solutions. Slide <42>
  • 43. How to achieve these objectives ?• First pad steam treatment based on enzymatic desizing and strong hardness and heavy metal complexing. Without the use of NaOH in this first pad steam treatment water consumption can be reduced.• Reduce the amount of alkali in the second pad steam bleach so that also there water can be reduced.• Low alkali bleaching treatments are safer for the material, especially for the Elastane fibres.• Lower amounts of caustic and peroxide in combination with a good clean up of the material using complexing agents gives less fibre damage, higher Dp values and tearstrengths. Green Solutions. Slide <43>

  • 62. Technical features of TANALEV® K-DC 01TANALEV® K-DC 01: One of the main characteristics to be highlighted is that it remains active during the whole process with its wetting, detergent, emulsifying and dispersing actions. Its effectiveness is maintained in the whole temperature range even with large amounts of electrolytes. This differs from conventional nonionic products whose turbidity level decreases together with their best characteristics. (1) TANALEV® K-DC 01 (2 & 3) Conventional nonionics Due to its anionic characteristics it does not affect the dyeing agents during the dyeing process. Low foam level compared with other alternative anionic products. Pronouncing Right-First-Time processing.Green Solutions. Slide <62>
