Fiber Production
Varies widely, but producing 1 kg of polyester can consume over 500 liters of water. Sustainable alternatives include recycled polyester and lyocell.
Cotton Growing
Approximately 2,700 liters of water per T-shirt. Sustainable alternatives include organic cotton, rain-fed cotton, and better irrigation technology.
Washing Raw Fibers
Water consumption is high but varies; sustainable alternatives include using recycled water and efficient washing machines.
Wet Processing
Involves high water use; sustainable alternatives are plasma treatment, laser etching, and ozone treatment.
Dyeing and Finishing
Can use up to 100-150 liters of water per kg of fabric. Sustainable alternatives include using natural dyes, digital printing, and waterless dyeing technologies.
Printing
Uses large volumes of water; sustainable alternatives include digital printing and using water-based inks.
Yarn Preparation
Water usage is moderate; sustainable alternatives include using dry spinning techniques and closed-loop systems.
Fabric Production
Water usage depends on the technique; weaving uses less than knitting. Sustainable alternatives include air-jet weaving and sustainable knitting technologies.
