  1. Total Textile Process at a Glance

  2. Water is very important resources in our Ecology. We use this resource in different purposes. In textile, water is a part & parcel component without this nothing can be dyed properly. We use a huge quantity of water in dyeing section. As a result waste water is increased makes water pollution and thus the amount of this vital resources is reduced.

  3. Usage of Water In Textile Boilers 10% Finishing 13% Batch Dyeing 50% Preparation 27% Batch Dyeing Preparation Finishing Boilers

  4. Water Resources are limited and we need to handle them reasonably and responsibly. The environmental impact of textile production is considerable due to the vast quantity of water required and the variety of chemicals used that generates waste. Therefore, Water consumption Should be reduced in textile.

  5.  Bio-Scouring Method  Solvent Dyeing  Air Dyeing  Plasma Dyeing  Enzyme Dyeing  Compressed & Pressurized CO2 Dyeing

  6. In bio- scouring process only one bath is used before the actual dyeing starts, whereas in conventional process a minimum of 5 baths are used. This leads to a total 4 bath saving. Considering an MLR of 1:7, the total amount of water that will be saved is about 28 liters for every Kg. processed. For a unit doing a 30 Mt. of bleaching every day, the amount of water that will be saved is 840,000 Liters per day. On annual basis the amounts comes to be 306600,000 liters of water.

  7. With pectinases(enzyme) have shown promise in replacing the traditional alkakine scouring treatment. Some auxiliaries’ suppliers have introduced an enzymatic process to remove hydrophobic and other non-cellulosic components forn cotton. The new bio-scouring process operates at mils pH conditions over a broad temperature range and can be applied using equipment such as jet machines. It is claimed that, due to a better bleach ability of enzyme-scoured textiles, bleaching con be carried out with reduced amounts of bleaching chemicals and auxiliaries. Bio-scouring enzymes actually make the substrate more hydrophilic (which could explain better bleach ability), but they are not able to destroy wax and seeds which are therefore removed in the subsequent bleaching process. There is no need for the use of caustic soda in enzymatic scouring. So this process reduced pollution loads, high TDS, BOD and COD in the effluent.

  8. A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyeing is a dyeing process carried out from a continuous non-acqueous phase. Here solvent is used as dyeing media. But water may be added to assist dyeing process. Since the introduction of hydrophobic fibers like cellulose acetate in 1920’s solvent have been considered for Dyeing because it was not possible to dye such Fibres with ionic dyes and water.

  9. Some solvents of chlorinated hydrocarbons of aliphatic series posses most of the mentioned requirements and hence are being used as solvents are extensively used such as – 1. Tri-chloro Ethylen (TCE). 2. Per-chloro Ethylen (PCE). 3. Methyl Chloroform (MC). All three solvents are almost equally suitable but tri-chloroethylene has very high stability to decomposition and hence isomers preferable.

  10. Air Dye technology manages the application of color to textiles without the use of water.It was developed and patented by Colorep, a California-based sustainable technology company.The process of making textiles can require several dozen gallons of water for each pound of clothing. The Air Dye process employs air instead of water to help the dyes penetrate fibers, a process that uses no water and requires less energy than traditional methods of dyeing, The technology works only on Synthetic material and is currently available only in the United States.

  11. Airflow Dyeing Machine

  12. Gas Evaporate Curve

  13. AirDye® Technology AirDye Solids AirDye Singles AirDye Wovens AirDye Contrast AirDye contrast dyes opposite sides of fabric two different colors. AirDye Singles prints one side of fabric while leaving the other side undyed. AirDye Wovens simulates dyed woven jacquard and dobby weave. AirDye Solids dyes both sides of a fabric a single color. Print-to-Solid AirDye Imprints Print-Contrast Print-Squared Print-Squared prints opposite sides of fabric with the same design. AirDye Imprints dyes or prints an image or logo on fabric. Print-Contrast prints opposite sides of fabric with different designs. Print-to-Solid prints one side of fabric and dyes the other.

  14. 1. Water and Chemical (Disperse agent, Leveling agent, and RC agent) is needlessness 2. Drain treatment and Dryer is needlessness 3. CO2 is possible for recovery use(Recovery Rate 96%) 4. From these merits, we can say that Super- critical Dyeing and Treatment contributes to the environmental damage and it is not influenced by water resources. 5. 43% of energy reduction is possible.

  15. Low liquor ratio based dying machine

  16. Plasma, as a very reactive material, can be used to modify the surface of a certain substrate (typically known as plasma activation or plasma modification), depositing chemical materials (plasma polymerisation or plasma grafting) to impart some desired properties, removing substances (plasma cleaning or plasma etching), which were previously deposited on the substrate (Pane, et al 2001).

  17. Plasma technology is a surface-sensitive method that allows selective modification in the nm-range. By introducing energy into a gas, quasi-neutral plasma can be generated consisting of neutral particles, electrically charged particles and highly reactive radicals. If a textile to be functionalized is placed in a reaction chamber with any gas and the plasma is then ignited, the generated particles interact with the surface of the textile. In this way the surface is specifically structured, chemically functionalised or even coated with nm-thin film depending on the type of gas and control of the process.

  18. Various application of plasma in textile. APPLICATION MATERIAL TREATMENT Hydrophilic finish PP, PET, PE Oxygen plasma, Air plasma Hydrophobic finish Cotton, P-C blend Siloxane plasma Plasma consisting of dimethyl silane Oxygen plasma Antistatic finish Rayon, PET Reduced felting Wool Crease resistance Wool, cotton Nitrogen plasma Improved capillarity Wool, cotton Oxygen plasma Improved dyeing PET SiCl4 plasma Improved depth of shed Bleaching UV protection Polyamide Air plasma Wool Cotton/PET PAN, Cotton, Rayon Oxygen plasma HMDSO plasma Flame retardancy Plasma containing phosphorus

  19. There are many different ways to induce the ionization of gases. i)Glow discharge ii)Corona discharge iii)Dielectric Barrier discharge iv)Atmospheric pressure plasma technique.

  20. What BASF offers # Products that can bring the desired effect using fewer amount of chemical # Solutions that increase the efficiency of a process resulting in saving water and energy, as well as time and costs

  21. Eco-efficient Solutions Cyclanon®XC-W New: After-soaping agent for reactive- dyed cellulose fibers. Compared to the conventional process, it considerably shortens the processing time, saving both water and energy. Helizarin®ECOSOFT Printing System: Eco-efficient pigment printing solution that significantly reduces the consumption of water and energy compared to reactive printing due to its shorter processing time.

  22. Water-friendly enzymes enter the fashion world China is one of the world’s largest textile producing countries, contributing a sizable portion of the estimated 9 million tons of knitwear manufactured globally every year. With the production of 1 ton of cotton knitwear consuming what corresponds to the daily water usage of 600–700 urban Chinese people, the Chinese government recently intervened in an attempt to improve this use of resources. As of 2011, new legislation caps the maximum water consumption by textile plants at 100 tons of fresh water per ton of cotton knitwear. A life cycle assessment (LCA) reveals that enzymes can help manufacturers to overcome this challenge. Clear benefits of using enzymes Chinese manufacturer Esquel has performed several trials incorporating Novozymes’ enzyme-based solution known as elemental textiles. In the LCA, for the concept in use Esquel reported savings of 30 m3 (or 30 tons) of water per ton of knitted fabric in just a single bleaching process when substituting enzymes for chemicals.

  23. Eco-efficient Solutions Cyclanon®XC-W New: After-soaping agent for reactive- dyed cellulose fibers. Compared to the conventional process, it considerably shortens the processing time, saving both water and energy. Helizarin®ECOSOFT Printing System: Eco-efficient pigment printing solution that significantly reduces the consumption of water and energy compared to reactive printing due to its shorter processing time.

  24. As water is a viatl resources but it is poluued by different ways day by day. As a textile related persion it is our concern to minise the water consumption in textile sector to save the water resources from being polluted. We have already discussed about the some methods to reduce the use of water in textile sector

  25. • Evolution or revolution? – Right first time – Best available technology – Re-cycling – Liquid carbon dioxide – Marginalisation of cotton (Kyoto style targets) – Product labelling based on facts not hype

  26. • Water ‘use’ is not always an issue • Pollution is the major issue • Energy use associated with water use is a major issue • Focus on industry not domestic • Best practice could halve water consumption in dyeing
