Read the following passage and answer the questions:

Sustainable textiles are centred around manufacturers switching to organic cotton or making textiles from natural, easily renewable materials such as bamboo or hemp. But little attention has been paid to the dyeing process, which can be a potentially destructive industry in terms of chemicals, waste and water use. 4000 years ago humans first used water to carry colour to a piece of cloth. Initial water pollution began. Since then, more and more chemicals have been added to dye textiles, leading to the current worsening water pollution. Today the World Bank estimates that 17-20% of industrial pollution is caused by the dyeing and treatment of textiles. They have also identified 72 toxic chemicals in our waters that are caused solely by the dyeing of textiles, 30 of these are persistent.

Traditional dyeing can use 7 to 75 gallons of water per pound of fabric to dye just one piece of fabric.

Air Dye technology from California-based Sustainable Technologies is the solution our planet needs today. Air Dye technology prints and dyes without consuming water or emitting pollutants. By using air instead of water to dye fabrics, this technology reduces water consumption and pollution.

A sustainable technology of colouring textile is-

  1. Dyeing technology
  2. Traditional dyeing technology
  3. Air-Dye technology
  4. Water - Dye technology

Answer (Detailed Solution Below)

Air-Dye technology is considered a sustainable method for coloring textiles. Unlike traditional dyeing techniques that require large volumes of water, Air-Dye technology uses air to apply color to fabrics. This innovative approach significantly reduces water consumption and minimizes the environmental impact associated with textile production. Additionally, Air-Dye technology cuts down on energy usage and chemical waste, making it an eco-friendly alternative. The process also offers enhanced precision in color application, leading to less material waste and higher quality finished products. As the fashion and textile industry increasingly seeks sustainable solutions, Air-Dye technology stands out for its efficiency and environmental benefits.
